Abstract

The invention relates to a high strength PCN engineering plastic and a preparation method thereof. The high strength PCN engineering plastic is composed of the following raw materials in parts by weight: 10 parts of SAN resin, 35 parts of ASA resin, 4 parts of SMA resin, 0.3 part of antioxidant, 0.7 part of ultraviolet resisting agent, and 50 parts of PC resin. The high strength PCN engineering plastic is obtained by modifying common engineering plastic, and can be made into traffic protection products. The protection products (guard bar ends) made of the high strength PCN engineering plastic overcome the problems caused by traffic protection products made of common plastic of low strength, bad anti-aging property, and harms to humans and vehicles, can be used for a long time while the main properties will not degrade, greatly exceeds the weatherability of common engineering plastic, have a simple processing technology, and are suitable for being promoted and applied.

Description

technical field [0001] The invention relates to a high-strength PCN engineering plastic and a preparation method. Background technique [0002] For a long time, engineering plastics have been used more and more widely due to their high strength and easy processing properties, but the disadvantage of engineering plastics is that they cannot be used outdoors for a long time, and their products are prone to aging and cannot continue to play their due role; road guardrails The ends are usually made of metal. When the vehicle collides, the metal of the guardrail is easily inserted into the vehicle body, causing the accident of overturning and injuring the occupants of the vehicle. The use of high-strength plastics can greatly reduce the accidents of guardrails that injure the body and occupants. However, the strength of general-purpose plastics is not high, and it is easy to age, resulting in a decrease in the performance of the plastics, which cannot protect vehicles and person...
