Problems solved by technology

[0003] Although ABS has become one of the most widely used polymer materials due to its excellent performance, it is easily affected by external forces such as stretching, bending, and impact during molding and use, such as in the demoulding process of some special structures Affected by stretching and bending external forces, stress whitening occurs, which will affect the performance and quality of the product in severe cases
[0004] Existing patents on stress whitening are limited to PP materials and other materials that are prone to stress whitening, and have not covered materials such as ABS that have stress whitening under special circumstances.

Abstract

The invention belongs to the technical field of ABS materials, and discloses a stress whitening resistance ABS (Acrylonitrile Butadiene Styrene) composite material as well as a preparation method and an application thereof. The composite material comprises the following components in percentage by mass: 45-99% of ABS resin, 0.5-50% of modifying agent, 0.3-1% of antioxidant and 0.1-5% of machining additive. Due to addition of the modifying agent and by utilizing a formed 'island structure', microcrack is prompted to occur in the composite material, so that the impact energy can be absorbed, and the ABS composite material which maintains the good mechanics properties of the ABS resin and has the excellent stress whitening resistance effect can be prepared. As no additive for fixing color is needed to add, the stress whitening resistance ABS composite material provided by the invention can be also prepared into products with various requirements on color, and can be widely applied to different fields.

Description

technical field [0001] The invention belongs to the technical field of ABS materials, and in particular relates to a stress-whitening-resistant ABS composite material and a preparation method and application thereof. Background technique [0002] ABS plastic is a kind of engineering plastic with excellent performance. It is a terpolymer of polyacrylonitrile (A), butadiene (B) and styrene (S). It is a thermoplastic engineering plastic developed in the 1940s. The introduction of acrylonitrile in the ABS structure retains its rigidity and heat resistance, the introduction of butadiene improves its flexibility and impact resistance, and the introduction of styrene optimizes its gloss and processing fluidity. Due to its excellent electrical properties, chemical stability and impact resistance, it is widely used in household appliances, office equipment, instruments, transportation, building materials, daily appliances and packaging materials and other fields. In the production a...
