Problems solved by technology

Yet the epoxy resin auxiliary agent that this invention prepares is white lump, adds polypropylene material after grinding, thereby there is following problem: (1) because the particle diameter of this auxiliary agent is relatively large, even if grinding for a long time, also It is impossible to obtain a very fine particle size, which affects its dispersion in the material system, and uneven dispersion will affect the light transmittance of the material; (2) Since the additive particles and the polypropylene material are physically blended, Therefore, it is impossible to achieve complete uniform distribution. Therefore, in the material system, some places have high mechanical properties, and some places have low mechanical properties, resulting in uneven distribution.

Abstract

The invention discloses a polyolefin composition, which mainly consists of the following components: 20-100 parts of polyolefin resin, 1-60 parts of epoxy-based polyhedral oligomeric silsesquioxane, 0.1-5 parts of crosslinking agent, Auxiliary cross-linking agent 0.01 to 1 part. The present invention adds a small amount of epoxy-based polyhedral oligomeric silsesquioxane, because polysilsesquioxane has many reactive groups, under the action of a crosslinking agent, it can form crosslinked bonds with polypropylene resin. The network structure realizes the strong chemical bond between the inorganic phase and the organic phase, thereby improving the mechanical properties such as rigidity and impact strength of the polyolefin material.

Description

technical field [0001] The invention relates to a polyolefin composition with high mechanical performance and a preparation method thereof, belonging to the technical field of polyolefin functional masterbatch. Background technique [0002] Polypropylene PP is one of the five general-purpose plastics. It has abundant sources of raw materials, is cheap, easy to process and shape, and has excellent comprehensive performance, so it has been widely used. As a semi-crystalline polymer material, PP has excellent properties such as high rigidity, corrosion resistance, and electrical insulation. In the polypropylene resin produced in general industry, the isotactic structure content is about 95%, and the rest is atactic or syndiotactic polypropylene. Due to its regular structure and high degree of crystallization, the melting point of polypropylene can be as high as 167 ° C. It has good heat resistance, corrosion resistance, surface stiffness and scratch resistance. However, polypr...
