摘要： PURPOSE:To make it possible to obtain a polyurethane molded item having excellent moldability, physical properties and electrostatic coating characteristics by using a low-molecular active hydrogen compd. contg. diaminotoluene and a low-molecular polyol at a specified ratio. CONSTITUTION:A polyurethane having a bulk density of 0.3g/cm or larger is obtd. by reacting an org. polyisocyanate (A) (NCO equivalent: 130-200), a high-molecular polyol (B) (a polyester polyol contg. a polyoxyethylene chain contg. 2-4 OH groups and a hydroxyl equivalent of 750 or larger) and a mixture (C) of a low-molecular active hydrogen compd. (diaminotoluene) with a low- molecular polyol (hydroxyl equivalent: 30-100), wherein the equivalent ratios of the components are C/B=8-12, diaminotoluene/B=0.15-1.0 and low-molecular polyol/B=8-12, in the presence of a catalyst and, if necessary, a foaming agent, a foam stabilizer and other auxiliaries by reaction injection molding.

摘要： PURPOSE:To markedly reduce the number of coating operations applied on the cavity surface of molds at molding operation by a method wherein magnetic powder is dispersed in polymer forming flat releasant films, which do not break at the removal from the molds, when applied on the molds. CONSTITUTION:Polymer 10 with high cohesive failure strength is employed as the main component of releasant 7a so as to form flat releasant films, which do not break at removal from molds, when applied on the cavity 6 made by the molds. Fluoroplastic such as polytetrafluoroethylene or the like, fluororubber- based polymer such as copolymer mainly consisting of propyrene hexafluoride and vinylidene fluoride or the like and silicone-based polymer such as polymethyl phenylsiloxane or the like is used as the polymer 10. Magnetic powder 10 is contained in the releasant 7a. Because normally ferrous material, which is magnetic, is used for a mold 1, the releasant 7a is attracted to a bottom force 3 side and brought under the state being kept on adhering to the surface of the bottom force 3. Consequently, when a worker touches the releasant film on the mold or when a molded part is removed from the molds, the probability of the separation of releasant film from the mold surface is small and no separation breakdown in the interior of the releasant occurs.

摘要： PURPOSE:To improve the fine reflecting property of the surface of coating without receiving any restriction in coloring and permit to apply this method on the molding of a large-sized molded product by a method wherein a resin is injected into a mold after adding and mixing either one of or both of polyether and isocyanate with specified transparent fibers as a filler. CONSTITUTION:Either one of or both of polyether and isocyanate is added and mixed with transparent fibers, having 6mum or less of an average fiber diameter and 250mum or less of an average fiber length, as a filler, thereafter, the resin is injected into a mold. According to this method, the microdispersion of the particles of the filler in the material of R.RIM is effected and a molded product having a smooth surface and good coloring property may be obtained. As a result, the coating surface of the molded product after coating becomes smooth uniformly and the fine reflective property of the coating surface may be improved remarkably. On the other hand, the filler can be obtained without necessitating a complicated manufacturing process such as in the preparation of a needle crystal type filler, therefore, the cost thereof is inexpensive.

摘要： PURPOSE:To mold laminated structure reliably and stably, by a method wherein synthetic resin for a skin material is cast to a boundary part with a gate casting the synthetic resin for a core material of a cavity through an injection runner which is different from that for core material injection and then the synthetic resin for the core material is injected through the gate. CONSTITUTION:In case of molding, for example, of a laminated structural body in a plate form, the bottom of a top force 1 and the top of a bottom force 2 are formed symmetric. In other words, a gate 4 narrowed so that a fluidized cross section becomes narrower than the inside of a cavity 3 is formed one one end side of the cavity 3 formed to a rectangular cross section of predetermined depth along the widthward direction of the cavity 3, a core material injection runner 5 is formed on the opposite side of the cavity 3 by placing the gate 4 between and a skin material injection runner 6 is opened at an end part of a gate 4 side of the cavity 3. When a skin material made of synthetic resin is cast within the cavity 3 through the skin material injection runner 6 and then the core material made of synthetic resin is injected from the core material injection runner 5 through the gate 4, it follows that the core material is made into the laminated structure wherein the same is wrapped in the skin material wholly.

摘要： PROBLEM TO BE SOLVED: To produce a composite resin composition having excellent physical properties by effectively utilizing semi-rigid or rigid polyurethane resin waste and formulating reactive resins, non-reactive resins, polymer alloy of thermoplastic resins thereto. SOLUTION: The objective composite resin composition is formed by kneading crosslinked polyurethane resin together with reactive resins, non-reactive resins or alloy resins over a specific temperature to give the objective composite resin composition of cross-linked polyurethane resin with a reactive resin, non- reactive resin and alloy resin. The objective composite resin composition is obtained by formulating crosslinked polyurethane resin hydrolyzate and the solid fillers to the non-reactive resin and the alloy resins and kneading the mixture.

摘要： PURPOSE:To rapidly and satisfactorily decompose a reinforcing material- containing urethane resin to monomers while satisfactorily keeping the uniform dispersibility of the reinforcing material so that the reinforcing material may be used for reproduction of the resin or as a raw material for another use by decomposing a waste of the urethane resin in the presence of a specified amount of a decomposing agent at a specified temperature for a specified time. CONSTITUTION:A waste of a urethane resin containing a uniformly dispersed reinforcing material such as a whisker or a glass fiber is decomposed to monomers by applying a decomposition treatment to 100 pts.wt. waste of the reinforcing material-containing urethane resin in the presence of 5 to 20 pts.wt. decomposing agent composed mainly of an alcohol such as an aliphatic glycol at 240 to 350 deg.C for 1 to 30min.

摘要： PURPOSE:To obtain the title molding excellent in impact resistance, dimensional stability, etc., and can be electrostatically coated safely by adding a specified amount of a thiocyanate to a polyurethane resin molding. CONSTITUTION:An active hydrogen compound (e.g. polyether polyol) containing specified amounts of a thiocyanate (e.g. ammonium thiocyanate), a crosslinking agent, a catalyst, etc., is mixed with an isocyanate compound (e.g. diphenylmethane diisocyanate), and the mixture is poured into a sealed mold and reacted. The product is released from the mold to obtain the title molding comprising 100 pts.wt. polyurethane resin and 0.01-5 pts.wt. thiocyanate.

摘要： PURPOSE:To improve physical properties of a material such as dimensional stability or strength/rigidity, by containing a specific surface active agent in a mixed solution containing polyol, isocyanate and titanium acid potassium whiskers as a filler. CONSTITUTION:A surface active agent of a formula 1 is contained into a mixed solution, in a reaction injection molding method containing a reinforced material where the mixed solution containing polyol, isocyanate and titanium acid potassium whiskers as a filler is injected within a mold, reacted and a molded product is obtained. It becomes that the titanium acid potassium whisker does not display a sudden thickening to be followed by a mixed quantity and mixing of far larger quantity of the whisker becomes possible due to existence of the surface active agent of the formula 1. Therefore, the thickening can be controlled even if a mixed quantity of the titanium acid potassium whisker is increased up to an effective quantity as a urethane reinforced material. A facial defect such as agglomeration blobbing or a blister of a urethane injection molded product containing a titanium acid potassium whisker reinforced material is not generated, dimensional stability ascribable to strength and rigid properties, thermal expansion and a molding shrinkage factor such as the modulus of elasticity in binding and Izod impact strength are improved drastically especially and a further high-quality urethane molded product can be materialized.
