Anti-reflection and toughening high-isotactic PP material and preparation method thereof

Abstract

The invention discloses an anti-reflection and toughening high-isotactic PP material and a preparation method thereof.The anti-reflection and toughening high-isotactic PP material comprises the following raw materials in parts: 90-95 parts of polypropylene, 0.08-0.095 part of a nucleating agent, 1-4 parts of a stabilizer, 0.5-1 part of an antioxidant, 0.001-0.95 part of a flame retardant, 0.2-2 parts of alkyl peroxide, 0.04-0.2 part of a toughening agent and 2-4 parts of a transparent agent, and the proportion of the polypropylene to the nucleating agent is 1000: 1. The peroxide is specifically prepared by mixing hydrogen peroxide and dibenzoyl peroxide according to the proportion of 1: 4, the nucleating agent is prepared by mixing silicon dioxide, alum and calcium oxide according to the proportion of (2-6): (4-6): (6-9), and the stabilizer is prepared by mixing zinc stearate, calcium carbonate and calcium hydroxide according to the proportion of (1-2): (4-5): (5-10). The transparency of the PP material can be improved by adding various additives, the nucleating agent and the transparent agent on a common PP material, the toughness of the PP material can be improved by the flexibilizer, the stability of the PP material in the preparation process can be improved by the stabilizer, and the service life of the PP material can be prolonged by the antioxidant.

Description

technical field [0001] The invention relates to the technical field of PP materials, in particular to an antireflection and toughening high isotactic PP material and a preparation method thereof. Background technique [0002] PP material generally refers to polypropylene polypropylene, which is a polymer formed by addition polymerization of propylene; it is a white waxy material with a transparent and light appearance; the chemical formula is (C3H6)n, the density is 0.89-0.91g / cm3, and it is flammable , with a melting point of 189°C, softens at about 155°C, and has a service temperature range of -30 to 140°C; it can withstand the corrosion of acids, alkalis, salt solutions and various organic solvents below 80°C, and can decompose under high temperature and oxidation; Propylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc., and is also used in food and dru...

Problems solved by technology

[0003] In the prior art, the PP materials produced by traditional preparation methods and raw materials do not have high transparency and high toughness, and cannot adapt to the higher requirements of the use environment. Therefore, we propose an antireflection and toughening high isotactic PP material and its preparation method to solve the above problems
