摘要： 1328010 Aminoplast/addition copolymer compositions FORD MOTOR CO Ltd 22 Nov 1971 [1 March 1971] 54198/71 Headings C3G C3P and C3R A non-aqueous dispersion of a thermosetting film-forming polymer is obtained by copolymerizing at least one ethylenically unsaturated monomer containing an epoxy, hydroxy, cyanato or carboxylic acid group with at least one ethylenically unsaturated monomer lacking such a group in the presence of a copolymer of at least two ethylenically unsaturated monomers, all of which contain at least 4 carbon atoms and at least one contains at least 11 carbon atoms, and at least one of which contains an epoxy, hydroxy, cyanato or carboxylic acid group, in a medium which is non-solvent for the copolymer formed, and blending an aminoplast resin with the resultant dispersion. In the examples a first copolymer is prepared in butanol from 2 - ethylhexyl acrylate and hydroxypropyl methacrylate, plus, in Examples 2 and 4, butyl methacrylate, styrene, and acrylic acid; to the product solution is added an aliphatic naphtha and styrene, butyl and methyl methncrylates and acrylic acid, plus, in Examples 3 and 4, acrylonitrile and hydroxypropyl methacrylate; the catalyst used is butyl peroctoate in all cases; to the product dispersions is added an alkylated melamine-formaldehyde resin in xylene/butanol plus a mixed aliphatic/aromatic hydrocarbon solvent to give a lacquer.

摘要： 1315191 Thermosetting acrylic resin coating GENERAL MILLS Inc 11 June 1970 [11 June 1969] 28299/70 Heading B2E [Also in Division C3] Thermosetting acrylic resin compositions suitable for coating substrates such as steel, copper, aluminium, tin, glass and wood comprise (a) an acrylic resin obtained by copolymerising a monohydric alcohol ester of acrylic or substituted acrylic acid with an ethylenically unsaturated alcohol and (b) a sufficient amount (e.g. 0.1-80% based on the weight of acrylic resin) of a polyisocyanate to improve the impact resistance of the thermoset product obtained from the composition, said polyisocyanate having the formula: where y is 0 or 1, x is 2, 3 or 4 and R" is the hydrocarbon residue obtained after removal of the carboxyl groups from polymerised unsaturated fat acid(s). Preferred unsaturated fat acids from which the polyisocyanates are derived contain 16-22 carbon atoms. The ester component of the acrylic resin is preferably an alkyl acrylate or methacrylate; esters such as alkenyl, cycloalkyl, aralkyl and aryl esters may also be used. The alcohol component of the acrylic resin is preferably a partial acrylic ester of a polyhydric alcohol, e.g. a hydroxyalkyl acrylate or methacrylate; components such as allyl alcohol can also be used. The acrylic resin may optionally contain units of additional monomers, e.g. styrene, vinyl toluene, vinyl chloride, vinyl fluoride, vinyl acetate and acrylonitrile. The compositions may also include an aminoplast cross linking agent, e.g. a urea- or melamineformaldehyde resin such as a hexaalkoxyalkyl -melamine. The acrylic resin is preferably employed in an organic solvent solution, e.g. in an aliphatic or cycloaliphatic ketone or ester, an aromatic or aliphatic hydrocarbon, dioxane and glycol ether-esters. Optional additives which may be present include pigments and fillers, e.g. titanium dioxide; urethanation catalysts such as dibutyl tin dilaurate and stannic chloride pentahydrate; and acidic curing catalysts such as p-toluene sulphonic acid. The compositions can be applied to substrates by brushing, spraying, roller coating, dipping or by doctor blade, and the coatings can be cured by heating to 120‹-230‹C.

摘要： 1,232,162. Polyacrylate- and polyurethanecontaining coating lacquers. FARBENFABRIKEN BAYER A.G. 27 June, 1969 [10 July, 1968], No. 32577/69. Heading B2E. [Also in Division C3] Lacquer mixtures comprise at least one polyacrylate resin which contains carbonamide groups, is free from hydroxyl groups and has a molecular weight above 600, and at least one poly-N-alkoxymethyl urethane as cross-linking agent. The polyacrylate resin is a copolymer of (meth)-acrylamide with acrylic or methacrylic acid or an ester or nitrile thereof and, optionally, one or more other comonomers, e.g. allyl ethers, vinyl esters, maleic esters, styrene and vinyl toluene. The carbonamide groups of the polyacrylate resin may be partly reacted with formaldehyde and etherified. The poly-N-alkoxymethyl urethane is a reaction product of an N-alkoxymethyl urethane and a low or high molecular weight polyol. Suitable solvents for the lacquer mixtures include toluene, xylene, chlorobenzene, ethyl acetate, butyl acetate, #-methoxyethyl acetate, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, ethanol, butanol, ethylene glycol and mono-(C 1 -C 4 -alkyl) ethers thereof, and butylene glycol. The mixture may optionally include a melamine-formaldehyde or urea-formaldehyde resin; other optional components include inorganic or organic pigments, e.g. titanium dioxide, fillers, aluminium, bronze or zinc dust (anti corrosive and decorative agents), alkyd resins, adipate or phthalate plasticisers, levelling agents such as cellulose acetobutyrate, and acidic cross-linking catalysts, e.g. p-toluene sulphonic acid, phosphoric acid or maleic acid. Coatings obtained with the lacquers are cured by stoving. The lacquers are useful for application to implements and tools, for coating the insides of tins, for use as motor car lacquers, as luminous paint lacquers, for the production of chemically resistant protective coatings and for coating metallic tape. In Examples the lacquers are applied, by spraying, to degreased steel sheets which, in some cases, have first been treated with zinc phosphate or polyvinylbutyral-phosphoric acid zinc chromate.

摘要： 1,146,432. Laminates and laminating. DUNLOP CO. Ltd. 17 June, 1966 [20 July, 1965], No. 30730/65. Heading B5N. [Also in Divisions B2 and C3] A fibrous web of sheet material such as paper or a textile fibre, which may be in the form of a woven fabric or a non-woven fabric may be impregnated with a material comprising the reaction product of (a) a polymer of one or more episulphides having at least two reactive terminal groups and (b) a potentially thermosetting aminoplast by spraying, brushing, spreading and especially dipping techniques and composite laminate structures may subsequently be formed and if desired a layer of a non-fibrous material such as a strip of aluminium or other heat-resistant material may be included to confer heat-resistant properties on the impregnated fibrous material. The fibrous layers may be united together before the impregnating material is applied or they may be non-united layers which are united by the impregnating material itself giving a flexible composite fabric. Layers of fibrous web may be mechanically locked together, for example, by needling, or they may be impregnated and laminated together by means of conventional laminating resins, for example, aminoplastics or phenolin resins and the top web is then impregnated with the impregnating material giving a laminate, which is not usually flexible, having a working surface very resistant to alkali and to chipping. Drying of the impregnated fibrous web is effected at room temperature or at 70-80 C. and curing may be effected at 140-200 C. while the coated web is compressed between press platens. The examples describe the formation of laminates whereby both surfaces of a decorative paper web are coated with the impregnating material and also both surfaces of a white overlay paper web are similarly coated and the two coated webs air-dried, superimposed and pressed together for 10 minutes at 180 C. between chromium plates previously coated with a silicone release agent. The resulting sheet materials may be provided with a backing of adhesive, which may be covered with a release paper. The cured surfaces are resistant to staining by household liquids and cleaners. Uses:-Covering materials for kitchen shelves, walls and tables.
