Problems solved by technology

However, due to defects such as low mechanical strength, poor heat resistance, large shrinkage deformation, and poor creep resistance, polypropylene is greatly limited in application, especially as a structural material, and cannot be used as a high-performance engineering plastic.

Embodiment 1

[0017] A modified polypropylene material, which is composed of the following raw materials in weight percentage: 100 parts of polypropylene, 25 parts of ethylene-octene copolymer, 2 parts of modifier, 2 parts of acetyl triethyl citrate, and 7 parts of reinforcing agent 3 parts, 3 parts of diphenylguanidine, 10 parts of filler, 3 parts of zirconium silicate, 10100.2 parts of antioxidant.

[0018] As mentioned, the modifying agent is prepared by the following steps: according to the molar ratio of dimethyl diallyl ammonium chloride: acrylamide: itaconic acid is 1:1:1 In the reaction kettle with 60% distilled water and 1.5% sodium methacrylate in the total mass of the reactants, after 15 minutes of deoxygenation with nitrogen, add 3% of the total mass of the reactants with a mass ratio of 1:1. Block and hydrogen peroxide are used as initiators, react for 6 hours to obtain a copolymer aqueous solution with a molecular weight in the range of 4000-6000, which is the modifier.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a modified polypropylene material. Background technique [0002] Polypropylene is a semi-crystalline material that is harder and has a higher melting point than polyethylene. As a large class of general-purpose materials, polypropylene is widely used for its small specific gravity, easy processing, corrosion resistance, non-toxicity and excellent comprehensive performance. The PP engineering plastics and alloys that emerged in the mid-1970s replaced some general-purpose engineering materials and were used in industries such as automobiles, machinery, electronics, and electrical appliances due to their high performance and price ratio. However, due to defects such as low mechanical strength, poor heat resistance, large shrinkage deformation, and poor creep resistance, polypropylene is greatly restricted in application, especially as a structural material, an...
