Problems solved by technology

[0006] Although ABS has many advantages, due to the double bond produced by butadiene, its weather resistance is poor, and it is prone to aging, discoloration, and even cracking after long-term outdoor exposure, thereby reducing the impact strength and toughness of the material. It is flammable and thermally deformable. Low temperature

Abstract

The invention discloses a nano-modified ABS electric four-wheel vehicle reinforced anti-aging special material and a preparation method thereof. The raw materials are composed of the following components in parts by weight: 100-120 parts of ABS resin, 15-30 parts of polycarbonate, 5-15 parts of modified nanocrystal composite oxide, 8-14 parts of ethylene bis stearamide, 0.5-0.9 part of chlorinated polyethylene and 0.2-0.6 part of antioxidant. The nanocrystal composite oxide is shown in the following formula: TiaAlbMgcZndOX, wherein a is 0.1-0.5, b is 0.3-0.7, c is 0.2-0.5, d is 0.1-0.3 and X is greater than or equal to 1; the modified nanocrystal composite oxide is benchmarked against the weight of the nanocrystal composite oxide; and the nanocrystal composite oxide is obtained through the surface modification of 0.5wt% of the titanate coupling agent. On the basis of guaranteeing the original performance of the ABS resin material, the shock strength and the ageing resistance are increased, and the material is particularly suitable for being taken as the four-wheel vehicle fitting material.

Description

Technical field [0001] The invention relates to an ABS resin material, in particular to a nano-modified ABS electric four-wheel vehicle reinforced anti-aging special material and a preparation method thereof. Background technique [0002] In 1873, the British Robert Davidson invented the electric car using primary batteries as power, but it was not included in the international confirmation range. It is recognized internationally that the first electric car was born in 1881. The inventor was French engineer Gustave Truve. This is a tricycle powered by lead-acid batteries. Later, nickel-cadmium, nickel-hydrogen batteries, Lithium ion batteries and fuel cells are used as electric vehicles. [0003] The four-wheel electric vehicles currently on the market refer to pure electric vehicles with a maximum speed of less than 50 km / h, including electric sightseeing cars, electric golf carts, electric patrol cars, electric sanitation vehicles, electric transport vehicles, electric tractors,...
