Abstract

The invention discloses an anti-light aging nano TiO2-ABS (Acrylonitrile Butadiene Styrene) composite material. The composite material is composed of the following raw materials in parts by weight: 55-85 parts of ABS resins, 8-25 parts of nano TiO2, 0.1-1 part of a coupling agent and 0.2-0.5 part of a hyperdispersant. The nano TiO2-ABS composite material disclosed by the invention is high in anti-light aging property, environmental-friendly and resistant to high-temperature deformation and has an excellent mechanical property.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an anti-light aging nano TiO 2 -ABS composite material. Background technique [0002] As a thermoplastic engineering plastic, ABS is widely used in industrial fields such as machinery, automobiles, home appliances, and construction. However, after the addition polymerization of ABS is completed, there are still more active tertiary allyl hydrogen groups in a small number of chains. Under the action of light and oxygen, the butadiene chains are easily broken, resulting in the photoaging degradation of ABS. Therefore, after the products made of ABS are used outdoors for a long time, macroscopic deterioration phenomena such as yellowing, cracking, loss of gloss, and decline in mechanical properties will occur, which further deteriorates the high-temperature deformation resistance of the ABS material, which has a low thermal deformation temperature. Therefore, the pros ...
