Patent ES-267701-A1 (ES)
Title: Production of foamed thermoplastic articles
Inventor: LIGHTNER GENE E
IPC: B29C44/28
Filed: 1961-05-26
Abstract: Foamed thermoplastic articles, e.g. sheets, are made by forming a dry, friable, foraminous mass of desired shape from particles of one or more thermoplastic materials, with average particle size less than 100 microns and a glass transition temperature of at least 50 DEG C., applying to the shaped mass a vaporizable foaming agent, and heating the mass to expand the particles and cause them to adhere to one another. The foaming agent is an organic compound boiling at -10 DEG to 80 DEG C. at atmospheric pressure, and with not more than a slight solvent action on the thermoplastic material, or is a mixture of 70-98% by weight of one or more such compounds with 30-2% of an organic solvent for the thermoplastic. Suitable thermoplastic materials are ethyl cellulose, cellulose acetate, cellulose acetatebutyrate homopolymers and interpolymers of substances such as vinyl chloride, vinyl bromide, vinylidene chloride, ethylene, propylene, isobutylene, vinyl acetate, vinyl propionate, vinyl <PICT:0997583/C3/1> <PICT:0997583/C3/2> benzoate, vinyl methyl ether, vinyl isobutyl ether, acrylic or methacrylic acid or ester, acrylamide, acrylonitrile, styrene, vinyl toluene, ethyl styrene, dimethyl styrene, chlorostyrene, dichlorostyrene, vinyl naphthalene, maleic anhydride, diethyl maleate and dibutyl fumarate. Blends, e.g. of polystyrene with rubbery diene polymers, or graft copolymers, e.g. of styrene with a rubbery diene polymer may be used. Suitable vaporizable foaming agents are listed. The dry, friable shaped mass is preferably prepared by a layer of latex of thermoplastic material by removal of water at temperatures below the fusion point of the thermoplastic polymer, or by coagulating a film of latex on to the surface of a mould dipped therein. Examples describe the formation of foamed polystyrene sheets either unsupported or bonded to backing sheets, e.g. of paper. Foaming agents employed are: pentane and a pentane-acetone mixture. Fig. 1 illustrates apparatus in which a sheet of paper 20 is coated on one side in the nip of rollers 21, 22 with a film 24 of latex and passes through oven 32 when water is evaporated, and between rolls 37, 38 where a film of vaporizable foaming agent is applied. The coated, impregnated sheet passes into steam chest 46 in which the thermoplastic particles are foamed and caused to adhere together to form a foamed sheet 48 attached to paper sheet 20. Fig. 4 shows a similar arrangement for foaming an unsupported foamed sheet, the layer of latex, e.g. of polyvinyl chloride, being evenly spread by doctor blade 56 on endless band 54, dried by infra-red heaters 60, sprayed at 62 with foaming agent, e.g. dichlorodifluoromethane, and foamed in steam chest 64.
