Problems solved by technology

In the process of daily use of the car, people accidentally touch these parts, especially if hard objects touch and scratch, it will cause whitening and other phenomena on the interior parts, which will affect the appearance. Developed relevant test standards for scratch resistance
At the same time, as an automotive interior material, it also needs to meet the requirements of low odor. Some anti-scratch agents have irritating odors, which cannot meet the odor requirements of automotive interiors.
[0003] At present, the scratch resistance is mainly improved by adding additives to reduce the surface friction coefficient of the modified PP material. There are two main methods, the first: erucamide, which has the advantage of meeting the scratch resistance requirements and lower price, but The weather resistance test exceeds 350 hours, and the surface has precipitation and stickiness, which cannot meet the standards of the automotive industry
Second: p

Abstract

The invention relates to a talcum powder master batch and a preparation method thereof. The talcum powder master batch is prepared from the following raw materials in parts by weight: 11-30 parts of polypropylene, 3-10 parts of a compatilizer, 5-10 parts of a siloxane master batch, 60-70 parts of talcum powder, and 0.3-0.6 parts of an anti-oxidant, wherein the compatilizer is formed by polyolefinresin and dialkyl-terminated amino silicon oil; and the polyolefin resin is a copolymer of propylene and ethylene. The polyolefin resin is specifically selected to be combined with the dialkyl-terminated amino silicon oil, the effect of the compatilizer is achieved, and good infiltrating and coating effects are realized for the talcum powder. Dispersion of the talcum powder in PP resin is improved, scratch resistance is improved, and a dosage of the siloxane master batch can be reduced, so rigidity of a material can be further improved, and cost is reduced under the precondition of the good scratch resistance.

Description

technical field [0001] The invention relates to the field of polymer compositions, in particular to a talcum powder masterbatch and a preparation method thereof. Background technique [0002] Talc powder filled polypropylene materials have been widely used in automotive interior parts such as door panels, instrument panels, sub-dashboards, glove boxes, etc. In the process of daily use of the car, people accidentally touch these parts, especially if hard objects touch and scratch, it will cause whitening and other phenomena on the interior parts, which will affect the appearance. Relevant test standards for scratch resistance have been formulated. At the same time, as an automotive interior material, it also needs to meet the requirements of low odor. Some anti-scratch agents have pungent odors, which cannot meet the odor requirements of automotive interiors. [0003] At present, the scratch resistance is mainly improved by adding additives to reduce the surface friction co...
