Abstract

The invention discloses a novel layered material composite long glass fiber reinforced polypropylene composite material and a preparation method thereof. The formula of the composite material is prepared from the following components in parts by weight: 5-15 parts of a layered material, 35-65 parts of conventional polypropylene resin, 20-30 parts of glass fiber, 1-3 parts of a compatilizer, 1-2 parts of carbon black master batch, 0.5-1.5 parts of an antioxidant and 0.5-1.5 parts of a light-resistant additive. Compared with a common long glass fiber reinforced material with the same trademark on the market, the long glass fiber reinforced polypropylene composite material prepared by the invention has the advantages that the basic raw materials comprise a certain layered composite material,and thelayered material has the specific physical adsorption characteristic and layered structure characteristic, so that the problem of emission of odor VOC and the like in the production and subsequent use processes of the long glass fiber reinforced material is reduced, and meanwhile, the long glass fiber reinforced material has relatively good lubricity. The final product not only has excellent emission performance and is easy to demould, but also keeps higher physical properties, and can be widely applied to the fields of automobile materials, municipal engineering and the like.

Description

technical field

[0001] The invention relates to the technical field of polypropylene materials, in particular to a novel layered material composite long glass fiber reinforced polypropylene composite material and a preparation method thereof. The material is suitable for the manufacture of automotive appearance parts, electrical accessories, municipal engineering supplies, etc. Background technique

[0002] With the gradual deepening of the concept of replacing steel with plastic and reducing the total weight to achieve energy conservation and environmental protection, more and more metal parts have begun to be replaced by high-performance resin products. Reinforced polypropylene has high tensile, flexural strength and modulus, which helps to realize the wide application of plastics in load-carrying parts of the automotive industry, and is also conducive to enterprises' goals of reducing energy consumption and costs and improving efficiency. Therefore, in recent years, rein...
