Abstract
The invention belongs to the technical field of polymer materials and relates to a modified polypropylene material and a preparation method thereof. The modified polypropylene material is prepared from the following components in parts by weight: 74-81.2 parts of polypropylene resin, 12-15 parts of a fire retardant, 4-5 parts of a flame retardant synergist, 0.3-1 part of a compatilizer, 0.2-0.5 part of an antioxidant, 0.3-0.5 part of a lubricant and 2-4 parts of a scratch-resistant agent. According to the high-gloss scratch-resistant V-0 flame-retardant polypropylene material, the bromine flame retardant with low melting point and the flame retardant synergist are reasonably proportioned, so that high glossiness of the material is guaranteed while the flame retardant grade V-0 of the material is reached; in addition, the material has the advantages of excellent scratch resistance, low cost, easiness for large-scale industrialization production and the like.
Description
technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a modified polypropylene material and a preparation method thereof. Background technique [0002] Now the V-0 flame retardant PP technology is very mature, and the common flame retardants used in polypropylene can be mainly divided into halogen flame retardants and halogen-free flame retardants. Halogenated flame retardants mainly include chlorine-based flame retardants and bromine-based flame retardants. If the surface gloss of the modified material is high, brominated flame retardants with low melting points, such as octabromo-S ether, have a low melting point. , It will melt during processing and can be well dispersed in PP, and because the S atom in the molecule is very compatible with PP, it will form a high-gloss surface, and the anti-scratch agent is made of high molecular weight Silane polymers also do not migrate to the surface of the material. In the existing ...
