Abstract

The invention relates to the technical field of lubricating agents, in particular to a papermaking water-based lubricating agent which is made of raw materials including, by weight, 11-21 parts of hydroxy silicone oil, 10-20 parts of sulfated castor oil, 10-20 parts of sodium stearate, 5-10 parts of triisopropanolamine, 20-30 parts of polyaspartic acid, 15-25 parts of propylene glycol and 150-450 parts of water. The invention further provides a preparation method of the papermaking water-based lubricating agent. Flowability of a coating is effectively improved by the papermaking water-based lubricating agent, the friction coefficient of coated paper is reduced, coating adaptability and paper smoothness and glossiness are improved, sticking of a coating roll is prevented, the lubricating agent is mainly applied to the papermaking coating of the coated paper, the preparation method is simple, and the water-based lubricating agent prepared by the method achieves the best effect.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a water-based lubricant 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 o...
