Problems solved by technology

[0002] The purpose of sizing during papermaking is mainly to make paper or cardboard have the ability to resist liquid diffusion or penetration. Surface sizing is mainly to apply appropriate amount on the surface of paper after the wet paper web is dehydrated to a fixed value in the drying section. The process engineering of sizing materials. At present, the surface sizing agents of corrugated paper are mainly liquid glues such as AKD and styrene-acrylic emulsion.

Abstract

The invention relates to a solid surface sizing agent for papermaking. The sizing agent comprises the following components by weight: 78-90 parts of ferrous sulfate, 5-20 parts of aluminum sulfate, 1-5 parts of maltodextrin and 2-8 parts of sodium sulfate. The invention has the advantages of simple preparation method, low cost and good sizing effect, can replace 30% of starch to reduce amount of starch, and has water resistance of 25g / m<2> and ring crush strength index of 8 N.m / g.

Description

technical field [0001] The invention belongs to the field of sizing agents, in particular to a solid surface sizing agent for papermaking. Background technique [0002] The purpose of sizing during papermaking is mainly to make paper or cardboard have the ability to resist liquid diffusion or penetration. Surface sizing is mainly to apply appropriate amount on the surface of paper after the wet paper web is dehydrated to a fixed value in the drying section. Currently, the corrugated paper surface sizing agent is mainly liquid glue such as AKD and styrene-acrylic emulsion. The process is complicated and the product stability is poor. In addition, 1 ton of paper needs 60~80kg of starch for sizing. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a solid surface sizing agent for papermaking. The sizing agent has a simple preparation method, low cost, good sizing effect, and effectively reduces ...
