Abstract
995,019. Moulding by spraying. IMPERIAL CHEMICAL INDUSTRIES Ltd. Sept. 30, 1963 [Oct. 4, 1962; Nov. 16, 1962], Nos. 37645/62 and 43401/62. Heading B5A. [Also in Division B2] In a spraying process for manufacturing a plastics article use is made of a former of electrically conducting material and an electrostatic atomising spray gun. The gun 2, 3 ejects atomized spray of a vinyl chloride polymer paste in the form of particles having an electrical charge opposite to that on the former 1 which is thereby coated. The coating is then heated to gel and is subsequently stripped from the former. The spraying and heating may be repeated several times. The former may be rotated during spraying. The former may receive a fabric covering prior to spraying. A plurality of formers carried by a rotating support may be provided. The vinyl chloride polymer can be a homopolymer of vinyl chloride or a copolymer of vinyl chloride containing up to 20% by weight of a copolymerizable monomer. Suitable monomers include vinyl acetate, vinylidene chloride, ethyl acrylate, methyl methacrylate and the dialkyl fumarates and maleates. Mixtures of copolymerizable monomers, such as vinyl acetate and maleic anhydride may be used. Suitable plasticizers include alkyl phthalates, isophthalates and tenephthalates. Other ingredients such as fillers, thickening agents, pigments, stabilizers and release agents such as ethyl palminate or silicone compounds may be used. Spraying may be aided by the addition of diluents such as white spirit, toluene, xylene.
