Abstract

The invention relates to a solid surface sizing agent for paper-making as well as a preparation method and application thereof. The solid surface sizing agent for paper-making comprises the following raw materials in parts by weight: 75-90 parts of ferrous sulfate, 1-5 parts of manganese sulfate, 1-5 parts of paraffine, 2-5 parts of sodium sulfate, 1-3 parts of boric acid, 1-10 parts of bentonite and 1-5 parts of polyvinyl alcohol. The solid surface sizing agent is simple in preparation method, high in curing speed and low in cost and can be cured immediately after leaving a machine; the water resistance and the annular pressure index of paper can be improved on the premise of replacing 20%-30% of sizing starch with the solid surface sizing agent; in addition, paper or a paperboard subjected to sizing with the surface sizing agent disclosed by the invention does not have the problem of damping in summer.

Description

technical field [0001] The invention relates to a solid surface sizing agent and its preparation method and application. Background technique [0002] With the rapid development of the paper industry, waste paper pulp has become the main source of paper pulp in my country. This move can solve the shortage of pulp, but the recycled fiber in the recycled waste paper pulp becomes shorter, which has a great impact on the quality of the paper, and the ring compressive strength is reduced, which cannot meet the requirements of customers. In recent years, the industry has made many technological innovations, including trying to add PVA to increase the ring pressure during the surface sizing process. Although the ring pressure has been improved to a certain extent, the high production cost has discouraged enterprises, and the summer paper The phenomenon of resurgence is obvious. Therefore, the paper industry urgently needs a new surface sizing agent product with low cost and good ...
