Problems solved by technology

[0006] However, the wear resistance of traditional polypropylene is poor, and it is easy to cause damage after long-term friction. In order to improve the wear resistance of polypropylene, inorganic lubricants, such as graphite powder, are often added to it. These inorganic lubricants are compatible with polypropylene. Poor tolerance, easy to reduce the stability of the finished polypropylene

Abstract

The invention discloses an aerogel lubrication plastic material. The aerogel lubrication plastic material is prepared from, by weight, 3-4 parts of linoleic acid, 0.1-0.2 part of copper naphthenate, 0.7-1 part of 2-bromo-4-methylphenol, 1-2 parts of diisopropyl ethanol amine, 4-6 parts of hydroxyethyl cellulose, 0.8-2 parts of 3-aminopropyl trimethoxy silane, 1-2 parts of sucrose acetate isobutyrate, 13-20 parts of silicon dioxide aerogel, 1-2 parts of dithiosalicylic acid and 110-130 parts of high-density polypropylene. By adding of cellulose ester solution, oxidation resistance of finished products of the plastic material can be improved to further improve storage stability, and toughness and dynamic strength of the finished products can be improved. By adding of the silicon dioxide aerogel, high compatibility to a polypropylene base material is achieved after organic treatment, and high dynamic stability and excellent comprehensive performances of the finished products are realized.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to an airgel lubricating plastic material and a preparation method thereof. Background technique [0002] Polypropylene is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials; [0003] The chemical stability of polypropylene is very good, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to various other chemical reagents, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can soften polypropylene and Swelling, and its chemical stability increases with the increase of crystallinity, so polypropylene is suitable for making various chemical pipes and fittings, and has good anti-corro...
