| titleOfInvention | A kind of high temperature resistant modified filter membrane and preparation process thereof |
| abstract | The invention discloses a high temperature-resistant modified filter membrane and a preparation process thereof, comprising a polypropylene base membrane and a modified membrane. The upper and lower sides of the polypropylene base membrane are each coated with a layer of modified membranes. The raw materials are as follows, in parts by weight, including 50-60 parts of polyvinylidene chloride, 5-6 parts of ethylene-alkyl acrylate copolymer, 5-7 parts of benzophenone, and 1-3 parts of butyl lithium , 2-4 parts of 4-hydroxymethyl piperidine, 0.5-1 part of heat stabilizer, 1-3 parts of dispersant, 5-7 parts of adhesive, 0.5-1 part of inorganic filler, 2.5-3 parts of plasticizer , the heat stabilizer is one or more mixtures of barium stearate, lithium stearate and epoxy stearate. Polyvinylidene chloride has symmetrical properties, strong flame retardancy, corrosion resistance and biodegradation resistance. It is modified with ethylene-alkyl acrylate copolymer, and the modified polyvinylidene chloride is Flexibility, cold and heat resistance have been improved. |
