Title: Improvements in the manufacture and production of coating and adhesive compositions and films therefrom
IPC: C08L1/08
Filed: 1930-04-17
Abstract: Coating and adhesive compositions and films are produced by incorporating cellulose drivatives or synthetic resins or both, with oily polymerization products of diolefines prepared for instance as described in Specification 328,908, [Class 95, Paints &c.], but without the employment of alkali metals as catalyst for the polymerization.  Suitable cellulose derivatives are corboxylates such as the acetate, nitrates, and ethers such as methyl, ethyl, and benzyl cellulose; and suitable synthetic resins are the condensation products of formaldehyde with a phenol or with urea, thiourea, &c., or condensation products of dicarboxylic acids with polyhydric alcohols.  Solvents or diluents are necessary for the production of lacquers and coating compositions, but for adhesive and binding agents the quantity of solvent may be very small or it may be dispensed with altogether. If desired, there may be added also natural resins, waxes, drying oils, driers, anti-agers, fillers, sulphur, sulphur chloride, or other vulcanizing agents and vulcanizing accelerators.  With considerable quantities of colouring materials and/or inorganic or organic fillers such as asphalt, lignin, &c., moulded articles may be made or solid structures may be used instead of pulverulent fillers such as fabrics, preferably wire fabrics such as are used for the production of reinforced glass.  The plastic mixtures may be employed for caulking, packing, or jointing purposes.  In examples (1) an oily polymer of butadiene is prepared by heating a mixture of butadiene, toluene, and benzene to 200 DEG C. in a pressure vessel while forcing in air until a pressure of 80 atmospheres is attained, and the product is dissolved in a mixture of butanol, toluene, xylene, and a solution of cellylose benzyl ether in methyl-cyclohexanone and butyl acetate; the mixture is an elastic lacquer; (2) an oily polymerization product from a mixture of butadiene and dihydrostyrene in air under pressure at 195 DEG  C. is mixed with butyl acetate butyl alcohol, cellulose nitrate and chromium green, yielding a lacquer; (3) an oily polymer of butadiene is prepared by heating butadiene mixed with benzene ligroin and xylene at 180 DEG  C. with air under pressure, is mixed with coumarone resin, butyl acetate, butyl alcohol and toluene yielding a lacquer; (4) an oily polymer of isoprene and tetrahydrostyrene is prepared by heating at 200 DEG  C. and is mixed with boiled linseed oil, cellulose acetate, coumarone resin, butyl acetate, butyl alcohol, toluene and little cobalt, naphthenate yielding a lacquer; (5) a mixture of butadiene, toluene and benzine is heated to 200 DEG C. in a pressure vessel, and air is forced in until the pressure reaches 80 atmospheres, the mixture is cooled, and the treatment repeated at 100 DEG  C. with the addition of toluene; the mixture is then mixed with a solution of cellulose benzyl ether in toluene, methyl cyclohexanone, and butyl acetate, yielding a lacquer; (6) an oily polymer of butadiene is prepared by heating a mixture of butadiene with toluene and ethylene-chlorhydrin at 200 DEG  C. in a closed vessel and separating the volatile constituents, is mixed with a solution of coumarone resin and gum dammar in toluene and butanol, while adding additional toluene, yielding a varnish which dried at 80 DEG  C. is highly resistant to chemical and mechanical influences. Specifications 328,812, [Class 70, Indiarubber &c.], and 334,961, [Class 95, Paints &c.], also are referred to.ALSO:Coating and adhesive compositions and films are produced by incorporating cellulose derivatives or synthetic resins or both, with oily polymerization products of diolefines prepared for instance as described in Specification 328,908, [Class 2 (iii), Dyes &c.], but without the employment of alkali metals as catalyst for the polymerization.
