Embodiment 2

[0024] The preparation method of embodiment 2 is: take the raw material according to the proportion by weight; step 2: add the polypropylene, styrene-butadiene transparent impact resin, SEBS grafted maleic anhydride and antioxidant that are weighed in step 1 Stir in a high-speed mixer until uniform to obtain a mixture; step 3: Put the mixture obtained in step 2 into a granulator for kneading, melting, extrusion, cooling, and pelletizing to obtain a low-gloss polypropylene material. Wherein, the granulator adopts a twin-screw extruder, the processing temperature is 195° C., and the screw speed is 400 rpm.

Embodiment 3

[0025] The preparation method of embodiment 3 is: take the raw materials according to the weight ratio; step 2: add the polypropylene, styrene-butadiene transparent impact resin, SEBS grafted maleic anhydride and antioxidant in step 1 Stir in a high-speed mixer until uniform to obtain a mixture; step 3: Put the mixture obtained in step 2 into a granulator for kneading, melting, extrusion, cooling, and pelletizing to obtain a low-gloss polypropylene material. Wherein, the granulator adopts a twin-screw extruder, the processing temperature is 210° C., and the screw speed is 200 rpm.

Abstract

The invention discloses a low-gloss polypropylene material and a preparation method thereof. The low-gloss polypropylene material comprises the following raw material components in parts by weight: 75-90 parts of polypropylene, 5-20 parts of butylbenzene transparent impact-resistant resin, 1-5 parts of SEBS grafted maleic anhydride and 0.1-1 part of an antioxidant. According to the invention, under the condition of not adding inorganic filler, the glossiness of polypropylene can be effectively reduced, and the application range of polypropylene is expanded.

Description

technical field [0001] The invention relates to the field of polypropylene materials, in particular to a low-gloss polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a widely used general-purpose plastic. It has many advantages such as abundant raw material sources, low density, low price, good comprehensive mechanical properties, non-toxic, corrosion resistance, and easy processing and molding. With the development of the automobile industry, the safety and comfort requirements of automobiles are getting higher and higher. The low-gloss polypropylene material makes the light inside the car soft and does not produce obvious mirror reflections, which reduces the interference to the driver and improves the driving experience. Safety and comfort. In addition, the surface of decorative materials in the home also tends to require a soft effect. Therefore, low-gloss polypropylene materials for automobiles, electrical appliance...
