Abstract

The invention belongs to the technical field of surface sizing agents, particularly relates to a formula of a high-performance anionic surface sizing agent, and provides the following scheme aiming atthe problems that the existing sizing agent is mainly cationic, is rarely disclosed by an anionic sizing agent technology and cannot meet the use requirements. The high-performance anionic surface sizing agent comprises the following important components in parts by weight: 2-4 parts of a flocculating agent, 3-6 parts of an inorganic waterproof agent, 3-5 parts of a reinforcing agent, 4-8 parts of an active agent, 1-3 parts of a defoaming agent, 3-6 parts of glycerol resin, 2-6 parts of a preservative, 4-8 parts of a thickener, 3-6 parts of an odor adsorbent, 2-4 parts of a bactericide, 2-4 parts of a buffer agent, 3-6 parts of an anionic emulsifier, 12-18 parts of a polyacrylamide solvent, 4-9 parts of a cationic adsorbent, 3-4 parts of an initiator, 4-8 parts of ammonia water and 10-24parts of water. The method is convenient to operate for producing the anionic surface sizing agent; the use performance is improved, and the use requirements can be met.

Description

technical field [0001] The invention relates to the technical field of surface sizing agents, in particular to a formulation of a high-performance anionic surface sizing agent. Background technique [0002] The surface sizing agent is applied on paper or cardboard to improve the water resistance, anti-fouling and ring pressure strength of the paper. Water-based polyurethane as a paper-making surface sizing agent is a research hotspot in recent years. For the emulsion of the sizing agent, Its biggest advantage lies in the formation of highly dispersed polyurethane sizing agent without adding other surfactants such as Tween, Span, and dodecyltrimethylammonium bromide as emulsifiers. The obtained emulsion sizing agent has Excellent stability and high dispersion performance, but relatively poor water resistance; with the excellent water repellency of silicone, it is widely used-polyurethane to form water-based silicone-polyurethane emulsion, which can combine the dual advantages...
