Abstract

The invention provides an environment-friendly papermaking coating using biological latex. The coating comprises the following components in percentage by weight: 10 to 20 percent of biological latex, 65 to 80 percent of heavy calcium carbonate and 1 to 15 percent of auxiliary material, wherein the biological latex is nanoscale modified starch, phosphate ester starch or modified soy protein. Paper produced by the environment-friendly papermaking coating using the biological latex has high printing surface intensity, high paper glossiness and printing glossiness and high food contact safety; by the produced environment-friendly papermaking coating, the cost of the papermaking coating is reduced, the quality of the paper can be improved when the coating is coated on the paper, the consumption of petroleum is reduced, the content of harmful substances in the coated paper is reduced, and the application of packaging paper is enlarged; and the coating is a real low-carbon environment-friendly papermaking coating.

Description

Technical field:

[0001] The invention relates to a preparation method of an environment-friendly coating for papermaking. Background technique

[0002] The existing market has higher and higher requirements for coated paper and cardboard. For packaging paper that is closely related to human life, it is required that it cannot contain harmful substances such as benzene series and other aromatic hydrocarbons. At present, most of the adhesives used for paper coating are based on Synthetic latex such as styrene-butadiene latex and styrene-acrylic latex are mainly used. The main raw materials of this synthetic latex are butadiene, acrylate and styrene. There are two disadvantages. One is that the raw material of synthetic latex is extracted from petroleum refining products. Petroleum is currently a relatively tense and important non-renewable resource in the world. With the rising price of petroleum, the price of synthetic latex for papermaking has gradually increased. Up to now,...
