Abstract

The invention belongs to the technical field of production processes of surface sizing agents, particularly relates to a production process of a high-performance anionic surface sizing agent, and provides the following scheme aiming at the problems that the quality of an existing animal glue surface sizing agent cannot be controlled in the production process, so that the use of a product is influenced in the later surface sizing process. According to the technical scheme, the method comprises the following steps: W1, preparing a reaction vessel, a crushing tank, a mixing and stirring kettle, atemperature controller, a filter, an evaporator, a gel machine and a dryer, wherein the temperature controller is connected with the mixing and stirring kettle; W2, crushing the animal raw materialsare put in the crushing tank; and W3, putting the crushed animal raw materials into a reaction vessel, and carrying out degreasing, alkali treatment and acid treatment. The production process is easyto operate and convenient to carry out, it can be guaranteed that the quality of a sizing agent is better when the sizing agent is produced, and therefore the product practicability is better when sizing is conducted on the surface.

Description

technical field [0001] The invention relates to the technical field of production technology of surface sizing agents, in particular to a production technology of high-performance anionic surface sizing agents. Background technique [0002] Surface sizing agent and neutral sizing agent. The common model QT-7N surface sizing is mainly to improve the smoothness of the paper surface, reduce the porosity, and prevent the surface from fluffing and shedding. Modified and unmodified starches are mostly used, and PVA is also used. Others include paraffin emulsion, animal glue, carboxymethyl cellulose, polyurethane, styrene-maleic anhydride copolymer, acrylic acid and acrylate copolymers, dihydroxy fatty acid compounds, etc. [0003] The quality of the existing animal glue surface sizing agent cannot be controlled during production, which affects the use of the product in the later stage of surface sizing. Therefore, we propose a production process for a high-performance anionic su...
