Abstract

The invention aims to provide alloy plastic, and in particular relates to PC-PPO (Poly Carbonate-Poly-p-Phenylene oxide) alloy plastic, and belongs to the technical field of high molecular materials. The plastic comprises the following components in parts by weight: 100-140 parts of polycarbonate, 40-60 parts of polyphenyl ether, 5-15 parts of a methyl ester-butadiene-styrene copolymer, 5-10 parts of dibutyl phthalate, 10-14 parts of polyvinyl butyral, 3-5 parts of tertiary butyl phenol-formaldehyde resin, 2-4 parts of polydimethylsiloxane, 3-5 parts of polyvinyl ethyl ether, 5-20 parts of aluminum silicate fiber, 15-25 parts of epoxy resin, 5-10 parts of white carbon black, 1-6 parts of anhydrous calcium sulfate, 1-3 parts of nanoscale titanium dioxide, 4-8 parts of polystyrene granules, 6-12 parts of chitosan, 3-5 parts of an antioxygen, 4-12 parts of a coupler and 3-5 parts of an uvioresistant agent. The mechanical property of the plastic corroded by acids and alkalis is decreased to a small extent. After high temperature and high humidity destructive test, the plastic still has good mechanical property which is superior to that of a control sample.

Description

[0001] technical field [0002] The purpose of the present invention is to provide an alloy plastic, in particular to a PC-PPO alloy plastic, which belongs to the technical field of polymer materials. [0003] Background technique [0004] Polycarbonate refers to a class of polymers whose macromolecular chains are composed of carbonate-type repeating structural units. The English name Polycarbonate, referred to as PC, is the second largest variety of general-purpose engineering plastics. According to the specific composition, PC can be divided into three types: aliphatic, alicyclic, and aromatic aliphatic-aromatic, but aromatic PC has practical application value in engineering, and bisphenol A with the largest output and widest application Mainly type PC, pure PC resin is an amorphous, tasteless, odorless, non-toxic, transparent, slightly yellow, white or colorless rigid and tough thermoplastic polymer; the relative molecular weight is generally 20,000 to 70,000 ;Slow burn...
