Embodiment Construction

[0013] The invention of this application has been concretely implemented, wherein 40 parts of magnesium hydroxide whisker material is added to 100 parts of ABS matrix material by mass, the mixing temperature is 170°C, and the mixing time is 10 minutes. After testing, the tensile strength of the prepared composite material is increased by 73.19%, the elastic modulus is increased by 71.4%, the elongation at break is reduced to 46.90% of the pure ABS base material index, and the oxygen index is 23.6.

Abstract

The application relates to a method for preparing ABS-based composite material and a product thereof. In the method, ordinary ABS material is used as a base stock; magnesium hydrate is used as additive; and under a certain technical condition, the base stock and the additive are mixed and refined in the weight proportion of 10-50 portions to be made into ABS-based magnesium hydrate whisker composite material. The diameter of the magnesium hydrate whisker used in the method is required to be less than or equal to 0.5 micrometer, and the length diameter ratio is more than or equal to 50. Compared with pure ABS material, the prepared composite material has good flame retardance and smoke suppression performances, and the tensile strength and the elasticity modulus of the material are all improved greatly.

Description

technical field [0001] A method and product for preparing an ABS composite material. Background technique [0002] ABS engineering plastics have excellent comprehensive properties, such as excellent impact strength, good dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and mechanical processing, and regeneration. It is widely used in various fields of the national economy, but this kind of material is easy to burn, the flame is yellow, and there is black smoke. After burning, the plastic softens and burns, and emits a special cinnamon smell, so a certain amount of cinnamon is usually added to this kind of material. Flame retardant, forming composite materials, thereby reducing the flammability of materials. Magnesium hydroxide powder is a new material for inorganic flame retardants. It does not release any toxic and harmful gases during the decomposition process, and it has better smoke suppression effect than inor...
