Low-luster polypropylene composite material and method for producing the same

Abstract

The invention discloses A polypropylene composite material with low luster and a preparation method thereof. The invention is characterized in that the material is formed by following raw materials by weight part: 56.5 to 98 parts of polypropylene, 0.2 to 1.5 parts of heat stabilizer, 0.3 to 1 part of light stabilizer, 0 to 20 parts of elastic bodies, 0.2 to 1 part of processing agent, 0 to 30 parts of inorganic filler, and 0.5 to 5 parts of silicon dioxide. The product of the invention has lower material luster, and the luster for the angle of 60 degrees on a smooth surface is lowered by 10 to 20 degrees than the primary product, thereby satisfying the requirement of low luster for material of people.

Description

technical field [0001] The invention relates to a low-gloss polypropylene composite material and a preparation method thereof, which can be used as an automobile interior material and belongs to the technical field of chemical materials. Background technique [0002] In the field of automotive materials, materials for cars represent the current highest level. At present, the maximum amount of interior materials used in cars is modified polypropylene, which accounts for more than 70% of the total amount of materials used. [0003] With the continuous progress of the society and the continuous development of the automobile industry, the automobile is not only a simple means of transportation, but the requirements for the safety and comfort of the automobile are also increasing. For example, when the car is driving, the external light is relatively strong, and if the interior material has a high gloss, it will form a relatively obvious light reflection, which will greatly inte...

Problems solved by technology

[0004] At present, no matter whether it is foreign or domestic materials, although the material properties meet the needs of the product, there are still deficiencies in some processing aspects. It needs to be made up by the manufacturer to increase the processing technology, thereby increasing the production cost, but it cannot fully meet the requirements. The user's requirements, the typical problem is: due to the high gloss of the existing materials, the injection molding factory can make matte texture or spray matte paint when making the texture to reduce the gloss of the product, but the cost increases , and sometimes it is still difficult to meet the usage requirements
