High-toughness antistatic foamed polypropylene and preparation method thereof

Abstract

The invention discloses high-toughness antistatic foamed polypropylene and a preparation method of the high-toughness antistatic foamed polypropylene. The high-toughness antistatic foamed polypropylene comprises the following components in parts by weight: 20-25 parts of colorless polypropylene particles, 10-15 parts of colored polypropylene particles, 2-4 parts of carbon black, 5-10 parts of an antistatic agent, 2-3 parts of a bacteriostatic agent, 3-5 parts of an anti-aging agent, 2-5 parts of a lubricant, 8-10 parts of cyclic fatty acid methyl ester, 4-8 parts of methyl phosphate and 3-5 parts of sodium dodecyl benzene sulfonate. The preparation method has the advantages of light weight and heat insulation, twice screening is carried out in the preparation process, particles with uniform sizes can be screened out each time, and uniform sizes of foamed polypropylene particles are guaranteed; added phenol can be mixed with trichlorotoluene and N-N '-diphenyl-p-phenylenediamine for use, the ageing resistance of the product is improved, bromine water is added in the preparation process, inert gas can be emitted in the combustion process, then the oxygen content is reduced, the certain flame retardant purpose is achieved, and the flame retardant property is improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene materials, in particular to a high-toughness antistatic foamed polypropylene and a preparation method thereof. Background technique [0002] Expanded polypropylene has the advantages of light weight and heat insulation, so it is widely used in daily necessities, industry, and agriculture. Expanded polypropylene needs to be obtained by cutting and foaming polypropylene. When cutting, the size of the cutting will be different, and the size of the foamed polypropylene particles produced at the end will be uneven. When the product is subsequently hot-pressed into a board, the internal cavity will be formed due to the different size, resulting in a decrease in strength. During the use of polypropylene, it is unavoidable to come into contact with air, water, etc., which will cause some fungi to form colonies on the surface of polypropylene, which will corrode polypropylene. The polypropylene avail...
