Abstract

The invention relates to weather-proof polycarbonate plastic which comprises the following components: 140 parts of polycarbonate, nanoscale titanium dioxide, 6 parts of polystyrene, 12 parts of chitosan, 2 parts of suberic acid, 20 parts of liquid paraffin, 4 parts of a plasticizer, 12 parts of zirconium phosphate, 2 parts of silver oxide, 7 parts of barium stearate, 1 part of polyoxyethylene ether, 2 parts of suberic acid, 5 parts of pentaerythritol, 5 parts of an antioxidant, 5 parts of a coupling agent and 9 parts of an uvioresistant agent. The plastic also comprises 12 parts of octadecanamide. After the plastic prepared by the invention is corroded by acid and alkali, the mechanical property is not reduced greatly; after a high-temperature high-humidity destructive test, the weather-proof polycarbonate plastic still has good mechanical properties.

Description

technical field [0001] The present invention relates to a kind of plastic, more specifically relates to a kind of weather-resistant polycarbonate plastic. Background technique [0002] Polycarbonate refers to a class of polymers whose macromolecular chains are composed of carbonate-type repeating structural units. It has excellent comprehensive properties and is an important engineering plastic. It has huge market potential in architectural lighting and automotive glass, but its disadvantages are low fatigue strength, easy stress cracking, high notch sensitivity, and poor wear resistance. Formic acid and acetic acid are also slightly corrosive to it. Polycarbonate has good stability to heat, oxygen, atmosphere and ultraviolet light. However, if it is used outdoors for a long time or exposed to strong light, its surface will become dark, tarnished, yellowed, and even cracked. Contents of the invention [0003] The technical problem to be solved by the invention i...
