Abstract

The invention discloses a papermaking coating granular superfine starch adhesive and a preparation method thereof. The starch adhesive is prepared from the following ingredients in parts by weight: 35to 60 parts of potato starch, 12 to 17 parts of bamboo carbon, 6 to 13 parts of sodium tetraborate, 5 to 10 parts of ethyl acetate, 7 to 14 parts of sodium acrylate, 10 to 22 parts of polyvinyl akohol, 7 to 13 parts of water glass, 6 to 10 parts of EDTA, 3 to 7 parts of dibutyl phosphate, 5 to 10 parts of zinc borate and 5 to 9 parts of nanoscale silver oxide. The starch adhesive disclosed by theinvention has the advantages of high stability, uniform particle size, good physical and chemical performance, ability in improving paper strength, simpleness and convenience in operation and abilityin reducing cost and reducing carbon emission; furthermore, the raw materials have wide source and can be generated again, and the particle size of an obtained product is small.

Description

technical field [0001] The invention relates to the technical field of starch adhesives, in particular to a granular superfine starch adhesive for papermaking coating and a preparation method thereof. Background technique [0002] Adhesives are the most important component of paper coating raw materials. It plays a decisive role in determining the viscosity, rheology, water retention and curing time of the coating, and has an important influence on the printing performance of coated paper. With the continuous development of paper coating technology, the types of coating adhesives are gradually changing. Synthetic latex adhesives are petrochemical products with non-renewable resources. They are high-carbon emission products with high cost. The starch used for coating comes from raw materials such as crop corn or potato starch. Its resources are widely renewable and have low carbon emission characteristics. The cost is low; therefore, in recent years, starch has been used mo...
