Problems solved by technology

Originally, due to the limitation of technical level and paper type requirements, surface sizing agents could only be used on special paper types. However, there are a variety of putty powder products on the market, but none of the surface sizing agents can really play a role. Obvious effect, but also there will be corresponding toxicity, affecting human health

Abstract

The invention discloses a styrene acrylic emulsion surface sizing agent and a preparation method thereof, and relates to the technical field of chemical raw materials. The sizing agent is prepared by compounding N-hydroxymethylacrylamide, acrylamide, an initiator, a compound emulsifier, styrene, acrylonitrile, and glyoxal according to a reasonable formula, processing the mixture, drying, and grinding. The preparation method has the advantages of simpleness, convenience, environment-friendliness, no pollution, easily-available raw materials, little equipment investment, and convenient operation. The prepared sizing agent has the advantages of good using effect, strong adhesive force, no side or toxic effect, and safety and reliability in application.

Description

technical field [0001] The invention relates to the technical field of chemical raw materials, in particular to a styrene-acrylic emulsion surface sizing agent and a preparation method thereof. Background technique [0002] Surface sizing is a process in the process of paper or cardboard processing. It is usually located at the end of the drying section of the paper machine. When the paper is not completely dry but has a certain strength, a layer of glue is sprayed on the paper and paper after subsequent drying. A layer of adhesive film is formed on the surface of the cardboard to achieve the purpose of changing the surface properties of the paper or cardboard. From the perspective of the development of the paper industry, surface sizing of paper is one of the indispensable processes. Through surface sizing, surface additives can be added to improve the performance of paper sheets or increase the water resistance of paper or cardboard. Originally, due to the limitation of t...
