Abstract

The invention relates to the technical field of lubricant, in particular to water-based lubricant for paper making. The water-based lubricant for paper making is prepared, by weight, by the following raw materials of 10-20 parts of sulfated castor oil, 8-16 parts of hydroxyl silicone oil, 1-5 parts of hydroxyethyl cellulose, 2-6 parts of hydroxy propyl methyl cellulose, 1-5 parts of methyl cellulose, 5-10 parts of polyphenylene sulfide, 8-15 parts of alkyl glycoside, 0.5-3.5 parts of polytetrafluoroethylene, 1-5 parts of sodium diacetate and 30-40 parts of water. According to the water-based lubricant for paper making, the good lubricating effect is achieved, the friction coefficients of coating paper are greatly reduced, the coating adaptability and the smoothness, glossiness and surface strength of finished paper are improved, no carcinogenic ingredient is contained in the raw materials, and environmental protection is achieved; the water-based lubricant for paper making is mainly applied in paper making coatings of the coating paper.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to water-based lubricants for papermaking. Background technique [0002] Lubricants are used in papermaking coatings to reduce the friction coefficient of the coating and improve the rheology of the coating to prevent paper powder from being produced during the manufacture of coated paper and subsequent modifications such as calendering, planting, etc., or to reduce the friction of coated paper In addition, it also has the function of improving the coating suitability of the coating (such as improving the rheology of the coating, etc.), improving the smoothness of the coating, and improving the gloss of the finished paper. At the same time, it can also prevent the sticking phenomenon of the coating roller. Lubricants for papermaking currently on the market are mainly high-grade fatty acid salts and high-molecular oxidized polyethylene, and also include wax emulsions, etc., all of...
