Starch-based adhesive with high binding power and good heat conductivity for paperboard

Abstract

The invention discloses a starch-based adhesive with high binding power and good heat conductivity for a paperboard. The starch-based adhesive with high binding power and good heat conductivity for a paperboard comprises the following raw materials in parts by weight: 40-80 parts of an acrylate adhesive, 20-40 parts of modified plant protein, 5-15 parts of lotus root starch, 1-3 parts of diphenylmethane diisocyanate, 1-2 parts of sodium hypochlorite, 1-2 parts of hydrogen peroxide, 1-3 parts of borax, 2-6 parts of a silane coupling agent KH-570, 2-6 parts of vinyl acetate, 1-2 parts of calcium carbonate, 2-10 parts of urea resin, 1-4 parts of sodium hydroxide, 2-10 parts of silicon dioxide, 1-6 parts of aluminium hydroxide, 1-4 parts of aluminium oxide, 1-5 parts of magnesium oxide, 0.1-0.8 part of ammonium persulfate, 1-5 parts of croscarmellose sodium, 1-3 parts of a stabilizer, 1-2 parts of a defoamer, and 10-30 parts of water. The starch-based adhesive is good in heat conductivity, high in binding power and excellent in waterproofing, toughness and stability.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a starch-based adhesive for cardboard with strong cohesive force and good thermal conductivity. Background technique [0002] Everyone in the glue production industry knows that the glue currently used to produce cartons, cartons and various cardboards not only has many steps and equipment, but also has a long production cycle, low production efficiency, and high cost. The functional groups and the outstanding characteristics of being able to meet the requirements of environmental protection, people have once again shifted their attention to starch adhesives. As an environmentally friendly natural adhesive, starch adhesives have attracted more and more attention from scholars. Starch is a kind of Natural polymer materials with a wide range of sources, low prices, and environmental friendliness are non-toxic, odor-free, and non-polluting. Starch-based adhesives have become one o...

[0002] Everyone in the glue production industry knows that the glue currently used to produce cartons, cartons and various cardboards not only has many steps and equipment, but also has a long production cycle, low production efficiency, and high cost. The functional groups and the outstanding characteristics of being able to meet the requirements of environmental protection, people have once again shifted their attention to starch adhesives. As an environmentally friendly natural adhesive, starch adhesives have attracted more and more attention from scholars. Starch is a kind of Natural polymer materials with a wide range of sources, low prices, and environmental friendliness are non-toxic, odor-free, and non-polluting. Starch-based adhesives have become one of the most potential natural adhesives. Usually, they need to obtain With high thermal conductivity, filling a large amount of inorganic fillers not only leads to a decrease in the adhesion of the product, but also the water resistance, toughness and stability cannot meet the needs
