Abstract

The invention discloses a starch adhesive. The starch adhesive is prepared from raw materials in parts by weight as follows: 40-50 parts of corn starch, 8-10 parts of borax, 10-12 parts of water, 6-8 parts of solid sodium hydroxide, 5-7 parts of pressure-sensitive adhesive composition, 6-10 parts of polypropylene glycol, 6-8 parts of polyol, 5-7 parts of potassium pyroantimonate and 1-2 parts of a synergist. The starch adhesive has the characteristics that surface strength of finished paper is excellent, linting and dusting trend is reduced obviously and the usage amount of latex is reduced.

Description

technical field [0001] The invention relates to the field of adhesives, in particular to a starch adhesive. Background technique [0002] In the laminating industry, adhesives are used for sizing, coating, glazing, and priming of various paper and cardboard. Compared with polyvinyl alcohol adhesives, starch adhesives have lower cost and better quality due to the lower price of raw materials and simpler manufacturing process. However, the existing starch binders are not reasonable and perfect because of their composition and content, and the water retention, fluidity and paper-forming performance of the coating cannot meet the specific needs of high-quality coated paper and cardboard. Contents of the invention [0003] The present invention provides a starch adhesive, the starch adhesive is almost tasteless, has wide application occasions and is suitable for wide use. Moreover, the formula is simple, the preparation method is simple, and it is easy to master. [0004] To...
