Abstract

The invention relates to special lubricating oil for production of PVC plastics and a preparation method of the special lubricating oil. The special lubricating oil comprises the following raw material components in parts by weight: 10-15 parts of propanediol, 2-4 parts of phosphite ester, 2-4 parts of magnesium stearate, 2-3 parts of tin stabilizer, 3-5 parts of a silane coupling agent, 2-3 partsof phenolic resin, 2-3 parts of sorbitol, 2-4 parts of dichloropropane, 1-2 parts of polyoxypropylene glycerol ether and 30-45 parts of dimethyl silicone polymer. The materials are easily obtained, stability is high, the lubricating effect is good, the moisturizing property of the PVC plastics is improved effectively, the toughness of the PVC plastics is enhanced, the pressure resistance is improved, the special lubricating oil is anti-bacterial, anti-oxidant, high-temperature-resistant, corrosion-resistant, waterproof and insulating, and the service life of the PVC plastics is prolonged.

Description

technical field [0001] The invention relates to a special lubricating oil for PVC plastic production and a preparation method thereof. Background technique [0002] During the production process of PVC plastic, lubricating oil needs to be added to achieve its own self-lubricating effect, otherwise it will easily lead to breakage and other phenomena. As far as the lubricating oil in the current market is concerned, none of them are special lubricating oils for PVC plastics. Desired effect, with less stability and reduced lubricity.
