Problems solved by technology

In recent years, research on improving and perfecting the application performance of styrene-acrylic emulsions has become increasingly active. Researchers have used polymer solutions or emulsions as emulsifying dispersants for styrene-acrylic emulsions to eliminate some of the shortcomings of traditional emulsifiers, but their emulsifying performance is poor. Disadvantages of high emulsion viscosity and poor stability

Abstract

The invention discloses a high-strength wrapping paper polymer surface sizing agent and a preparation method thereof. The high-strength wrapping paper polymer surface sizing agent has the molecular structure as shown in the specification. The preparation method comprises the following steps: causing polyethylene glycol, octadecanol and maleic anhydride to react to obtain maleic acid macrogol ester octadecanol ester; and carrying out copolymerization on maleic acid macrogol ester octadecanol ester, styrene, vinyl acetate, ethyl acrylate, hydroxyethyl acrylate and diallyl dimethyl-ammonium chloride with potassium persulfate and sodium bisulfate as initiators to prepare the high-strength wrapping paper polymer surface sizing agent. The obtained high-strength wrapping paper polymer surface sizing agent can favorably combine with paper fiber and has good film forming performance, and the water resistance and the ring crush compression resistance of the high-strength wrapping paper can be obviously improved.

Description

technical field [0001] The invention relates to the field of preparation of wrapping paper surface sizing agents, in particular to a high-strength wrapping paper polymer surface sizing agent and a preparation method thereof. Background technique [0002] my country has become a big country in paper production, consumption and import. The consumption of packaging paper accounts for more than half of the total output of paper and cardboard in the country. Among all packaging papers, the consumption of corrugated base paper and white board paper is the largest. Especially in recent years, with the rapid growth of my country's commodity exports, the quality requirements for commodity packaging paper have been continuously improved, which has put forward higher requirements for my country's corrugated base paper and white board paper manufacturers. Due to the long sea transportation time of export commodities and the high humidity of the sea air, it is easy to cause the packaging...
