Problems solved by technology

[0002] As a plastic lubricant, the lubricant needs to have good penetration and polarity to improve the stability of the plasticizing torque of plastic products. At the same time, in order to prevent the discoloration of plastics during processing, the lubricant should have good thermal stability; and in order to maintain the production efficiency and product quality of plastic products, it is best to require lubricants to have good dispersibility and low viscosity; and the existing lubricants do not have the above characteristics, thus affecting plastics. The production efficiency of products and the quality of plastic products need to be improved

Abstract

The invention relates to a compound lubricating agent and a preparation method thereof. The compound lubricating agent contains the following components in parts by weight: 5-15 parts of stearic acid, 10-30 parts of Fischer-Tropsch wax, 5-15 parts of oxidized polyethlene wax and 60-70 parts of polyethylene wax. According to the preparation method, the internal lubricating effect of stearic acid is well combined with an external lubricating effect of polyethylene wax, and Fischer-Tropsch wax and oxidized polyethlene wax are added, so that the needle penetration and polarity of the lubricating agent are increased, the plastifying time and plastifying torque of a plastic product are stabilized, and the integrated lubricating system is simply and conveniently used by customers. Production equipment is simple and high in economic benefit.
