摘要： PROBLEM TO BE SOLVED: To obtain a composite resin composition excellent in uniform dispersibility, improved in mechanical characteristics after molding and useful for effective utilization, etc., of a waste material of automobile bumper made of a polyurethane resin by kneading a crosslinked polyurethane resin with a reactive resin at a specific temperature. SOLUTION: (A) A crosslinked polyurethane resin [e.g. a (semi)cured urethane resin consisting essentially of a hydroxy compound, an isocyanate group- containing compound and a crosslinking agent and obtained by a reacting injection such as (R-)RIM molding] is kneaded with (B) a reactive resin (e.g. a thermoplastic resin having ester group, carboxyl group, carboxylic acid group, acid anhydride group, epoxy group, acryl group, amino group, hydroxyl group or oxazoline group, specifically, a polyamide resin or a polyamide resin-based alloy resin) at a temperature not lower than a melting temperature of the component B.

摘要： PURPOSE:To provide a method for recovering a useful reinforcing material (e.g. whisker) contained in a composite plastic in such a manner that deterioration, damage, lowering of physical properties and aggregate formation of the reinforcing material is suppressed and the reinforcing material is recovered in a dispersed state and can be recycled without requiring additional treatment. CONSTITUTION:This recovering method is applied to a composite plastic composed of a ceramics reinforcing material and a resin matrix for embedding the reinforcing material. The recovering method is composed of the first process where the composite plastic resin is subjected to alcohol decomposition, amine decomposition or hydrolysis by reacting with an alcohol, an amine or water, respectively to obtain a liquid decomposed product and the second process where the recovered reinforcing material having a resin residue on it is heated in a temperature range, in which the reinforcing material is free from deterioration nor damage, to decompose and remove the remained resin to obtain the reinforcing material free from the resin.

摘要： PURPOSE:To provide a method for recycling a resin component in which an operating efficiency is improved, safety of a molding operation is improved, and a recycled molded product having excellent external appearance quality and rigidity can be obtained. CONSTITUTION:A waste resin component is finely pulverized, finely pulverized waste material 14 is sealed in a fiber sheet bag 13 formed of a fiber sheet, the bag 13 is preliminarily heated, then set in molds 10, 11, 12, and hot-pressed. The bag 13 is formed by so sewing the sheet along a peripheral end of a product 16, and a metered material 14 is sealed. The product 16 is formed of a three-layer structure having a base material and fiber-reinforced plastic layers disposed at both sides of the material, and its rigidity can be effectively improved without increasing its thickness.

摘要： PURPOSE:To provide the recycling method of a polyurethane resin bumper, which is capable of obtaining a form, comparatively high in rigidity and suffi cient in the appearance of the surface thereof, simply with a low cost. CONSTITUTION:The method is provided with the process of pulverizing the waste material of a polyurethane resin bumper, a subsequent preheating process and a press molding process, effected by filling the pulverized waste material into a mold and, thereafter, effecting the press molding of the form by a hot press. A fiber sheet 14 is mounted previously on either one or both of the molding surfaces of a top force 12 and a bottom force 11 of the mold and, subsequently, hot-pressing is effected after filling the mold 10 with the pulverized waste material 13 whereby a fiber reinforced plastic layer 15a, consisting of the waste material and the fiber sheet, is formed on the surface of the molded form 15.

摘要： PURPOSE:To suppress the generation of flash to a large extent, to almost eliminate the generation of voids caused by the remaining of gas and to mold a foamed object excellent in quality in high yield by supplying a foamable raw material to which a flash seal material obtained by finely grinding a foaming material is added into a mold to foam the same. CONSTITUTION:A foamable raw material E to which a flash seal material A obtained by finely grinding a foaming material (e.g. polyurethane foaming material) is added is supplied into a mold 2 to be foamed. During this foam molding, the flash seal material added to the foamable raw material E is precipitated on a foamed object to enter the clearance between molds 2, 3 to prescribe the outflow of the molded object from the clearance and gas is discharged to the outside of the molds 2, 3 through the voids of the flash seal material A. By this method, the terminal flash generated on the obtained molded product becomes slight and the generation of voids caused by the remaining of gas is almost eliminated.
