Abstract

The invention relates to anti-aging polycarbonate-polyformaldehyde plastic. The anti-aging polycarbonate-polyformaldehyde plastic comprises 150 parts of polycarbonate, 80 parts of polyformaldehyde, 2 parts of dicapryl phthalate, 7 parts of zirconium phosphate, 4 parts of dioctadecyl thiodipropionate, 5 parts of silver oxide, 6 parts of ethene diamine, 1 part of isocyanurate, 7 parts of bisphenol A, 8 parts of aluminum hydroxide and 8 parts of barium sulfate. The anti-aging polycarbonate-polyformaldehyde plastic also comprises 6 parts of potassium isooctanoate. The anti-aging polycarbonate-polyformaldehyde plastic has high plastic strength, strong corrosion resistance, good weatherability, strong impact resistance, a low thermal aging degree, glycol resistance and high strength, produces small pollution on the environment, comprises domestic raw materials, accessory materials and additives, satisfies environmental protection requirements and greatly improves product market competitiveness.

Description

technical field [0001] The invention relates to a plastic, more specifically to an anti-aging polyphenylene ether plastic. Background technique [0002] Polycarbonate polyoxymethylene plastics are prone to aging, hardening and brittleness in long-term high-temperature and high-humidity environments, low thermal deformation temperature, high water absorption, low impact strength before water absorption, and a sharp drop in rigidity after water absorption. This limits the application of nylon 66, which in turn reduces the material selection options for design engineers in downstream industries. This shortcoming has become unacceptable and must be substantially improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-aging polycarbonate polyoxymethylene plastic. [0004] In order to solve the above-mentioned technical problems, the anti-aging polycarbonate polyoxymethylene plastic of the prese...
