4 results about "Chlorinated polyethylene" patented technology

The invention relates to a method for preparing a chloroprene rubber adhesive agent. The current products contain a large amount of methylbenzene and are poisonous. The invention comprises the following steps: firstly adding the chloroprene rubber and chlorinated polyethylene into a mixed solution (the compositions are 120# solvent oil, acetic ether, butanone, acetone and methyl carbonate) and mixing; after being entirely dissolved, filling nitrogen into the reactor; then adding methyl methacrylate and vinyl acetate and heating up to 80-100 DEG C; adding benzoyl peroxide to initiate a polymerization reaction; after 2-3 hours of the polymerization reaction, adding acroleic acid and adding additional benzoyl peroxide to continue reacting for 1-2 hours; after that, stopping the filling of the nitrogen and cooling to 30-50 DEG C; then adding 2,6-ditertiary butyl-p-cresol, mixing and discharging to obtain the chloroprene rubber adhesive agent. Therefore, the chloroprene rubber adhesive agent prepared by the method of the invention is environmental-friendly and has higher bonding strength to EVA soles. The method has the advantages of simple process and can realize large-scale production.

The invention belongs to the technical field of plastic and discloses a shell plastic for computer display screens and a preparation method of the shell plastic. The shell plastic is prepared from, by weight, 35-40 parts of acrylonitrile-butadiene-styrene copolymer, 15-20 parts of polycarbonate, 8-10 parts of polyvinyl chloride, 6-8 parts of polytetrafluoroethylene, 3-5 parts of chlorinated polyethylene, 5-7 parts of silicon rubber, 3-5 parts of polybismaleimide, 5-8 parts of 2-hydroxy-4-octoxydiphenyl ketone, 4-6 parts of molybdenum disulfide, 8-12 parts of red phosphorus, 7-9 parts of melamine polyphosphate, 16-18 parts of calcium carbonate, 10-13 parts of magnesium hydroxide, 7-11 parts of a plasticizer, 2-4 parts of a lubricant, 1-2 parts of a stabilizer and 2-4 parts of an antistatic agent. The shell plastic is simple in preparation, excellent in physical performance and great in fire resistance and high temperature resistance.

The invention discloses an alkali-resistant anticorrosive paint. The paint consists of two components A and B, wherein the component A consists of the following raw materials in parts by weight: 67-74 parts of epoxy resin E44, 20-25 parts of high chlorinated polyethylene resin, 10-16 parts of mica powder, 4-6 parts of titanium dioxide, 5-7 parts of sodium carboxy methyl cellulose, 4-6 parts dimethyl terephthalate, 4-6 parts of glycerol, 2-4 parts of ethyl acrylate, 2-3 parts of tung oil, 2-3 parts of polyacrylamide, 2-3 parts of diethylamine, 2-3 parts of triethyl O-acetylcitrate, 3-4 parts of ammonium dihydrogen phosphate, 4-5 parts of sodium molybdate, 2-4 parts of 2, 6-butylated hydroxytoluene, 9-12 parts of a compound modifying agent, 25-30 parts of dimethyl benzene, 8-10 parts of n-butyl alcohol, 0.8-1 part of anilino-methyl-triethoxysilane and 0.5-1 part of dimethicone. The produced paint has the advantages of good adhesion with metal, small structural pores, compact structure, excellent adhesion, good flexibility, high shock strength, strong corrosion resistance and efficient base metal protection function.
