Abstract

The invention provides glue coated test paper, as well as a preparation method and application thereof. The coated test paper comprises raw paper and paint coating the raw paper, wherein the paint is mainly prepared from the following raw materials in parts by absolute dry weight: 10-20 parts of calcined earth, 40-90 parts of porcelain clay, 10-20 parts of precipitated calcium carbonate, 2.5-3.5 parts of latex, 0.5-1.5 parts of coating starch and the balance of water. According to the preparation method, the paint formula in the glue coated test paper is regulated, and the coating process conditions are optimized, so that the prepared glue coated test paper has proper strength, smooth surface and low cost, is convenient and practical, and can meet the requirement of consumers for testing glue coated paper.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and relates to a sticky substance coated test paper, a preparation method and application thereof. Background technique [0002] Stickies in the paper industry are generally divided into two categories, one is natural stickies, such as resins, etc.; the other is recycled stickies, which are mainly derived from sticky substances in recycled fibers. With the increasing use of recycled fiber materials and the improvement of the white water sealing cycle in the paper industry, these stickies will gradually become larger and may generate secondary stickies that block the forming fabric, felt or dryer fabric, causing breakage. paper or downtime. [0003] If the existence of stickies can be predicted in advance during the production process, and corresponding measures are taken to deal with such stickies in the papermaking process, the operating rate of the paper machine can be improved. [0004] ...
