Embodiment Construction

[0024] The present invention will be further described below by way of examples and comparative examples. Under the condition of not violating the purpose of the present invention, the present invention should not be limited to the specific express contents of the following experimental examples.

[0025] (1) Examples 1-3 and Comparative Example 2 are mainly to evaluate the influence of adding different amounts of glass fiber on the system. Example 1, Example 2, Comparative Example 2, and Example 3 have glass fiber ratios of 2%, 5%, 10%, and 15% of the main components (except processing aids and antioxidants) respectively. Comparative example 3 is to replace the impact modifier 1 with the impact modifier 2, the impact modifier 1 is a silicone acrylic anti-impact agent, and the impact modifier 2 is polymethyl methacrylate-butadiene -Styrene core-shell structure anti-impact agent. The weight of each raw material is shown in Table 1. After drying and mixing, enter the twin-scre...

Abstract

The invention relates to a fiberglass reinforced black acrylonitrile-butadiene-styrene modified plastic capable of heat resistance and impact resistance, and its preparation method, which solves the problem of poor impact resistance of fiberglass reinforced composite material and simultaneously increases the heat resistance of a composite system. According to the invention, heat resistance and compatibility can be enhanced by adding multiunit random copolymers like heatproof styrene and maleimide, the rigidity can be raised by adding alkali-free staple glass fiber, and the linear expansion coefficient and molding shrinkage of the material can be reduced, simultaneously the impact resistance of a whole system can be improved by adding a silica acrylic acid system impact resistance modifier with small influence on mechanical property and heat resistance. The invention solves the problem that the impact resistance is rapidly decreased when the heat resistance and rigidity are raised. The method of the invention has the advantage of simple and clear technical scheme, and large scale production can be carried out.

Description

technical field [0001] The invention relates to a modified plastic material and a preparation method thereof, in particular to a heat-resistant, impact-resistant, glass fiber-strength black acrylonitrile-butadiene-styrene (ABS) modified plastic and a preparation method thereof. Background technique [0002] Glass fiber reinforced acrylonitrile-butadiene-styrene (ABS) composite material is a composite material made of acrylonitrile-butadiene-styrene as the matrix and glass fiber as the reinforcing material. Butadiene-styrene and glass fiber properties. Acrylonitrile-butadiene-styrene is a thermoplastic engineering plastic with a wide range of uses, used in machinery, electronics, electrical, instrumentation, household appliances, military and other fields. However, its tensile and bending strength is low, and its heat resistance is insufficient, so it cannot meet the application requirements of acrylonitrile-butadiene-styrene in automobiles. Glass fiber reinforced acrylonit...
