Problems solved by technology

[0003] At present, when polypropylene materials are used in automotive interiors such as dashboards and door panels, the surface is easily scratched and scratched during use, which affects the appearance of the car. Due to the poor scratch resistance of polypropylene, its application in automotive materials is affected
Therefore, automotive materials often need to add scratch-resistant additives. Due to the uneven dispersion of scratch-resistant additives, it is easy to cause inconsistent scratch resistance on the surface of the product, and easy scratches at local positions, which directly affect the appearance of the car, which seriously affects the appearance of the car. The qualification rate of automotive interior parts, and the use of traditional dispersant carriers such as PE wax and PP wax to improve the dispersion of scratch resistance additives will lead to sticky product surfaces and poor product odors.

Abstract

The invention discloses a low odor high dispersion scratch resistant additive masterbatch and a preparation method thereof, the scratch resistant additive masterbatch comprises the following raw materials by weight: 75-94.9% of low molecular weight polypropylene, 5-25% of a scratch resistant additive and 0.1%-2% of an antioxidant, by use of the lubricity of the low molecular weight polypropylene and polypropylene excellent compatibility, the prepared scratch resistant additive masterbatch improves the scratch resistant additive dispersion, reduces the scratch resistant additive dosage, and improves the compatibility of the scratch resistant additive and the polypropylene material, the product is good in flavor, and the scratch resistant additive masterbatch can be used for an alternative for traditional scratch resistant additive adding method.

Description

technical field [0001] The invention relates to a low-odor, high-dispersion anti-scratch auxiliary agent masterbatch and a preparation method thereof, in particular to a preparation method of an auxiliary agent masterbatch with simple process, good dispersion of anti-scratch auxiliary agent and low odor, which can be used in Replace traditional PE, PP-based masterbatch products. Background technique [0002] Polypropylene is one of the five general-purpose plastics. Due to its rich source of raw materials, low price, easy processing and excellent overall performance, it has a wide range of uses and has become the fastest-growing variety of general-purpose resins. It is widely used in automotive interior and exterior decoration of products. [0003] At present, when polypropylene materials are used in automotive interiors such as dashboards and door panels, the surface is easily scratched and scratched during use, which affects the appearance of the car. Due to the poor scr...
