Abstract

The invention relates to a starch based biomass functional adhesive and a preparation method thereof, and is particularly applied to the field of papermaking. The biomass functional adhesive comprises the following components: 30-45% of a biomass main raw material, 5.5-22.5% of a plasticizer, 0.55-3.5% of a lubricant, 0.55-5.5% of a crosslinking agent, 0.01-5.5% of a modifier, 0.55-5.5% of an auxiliary film-forming agent, 0.1-0.55% of a preservative, 0.01-5.5% of a pH regulator and the balance of water. The preparation method is as follows: adding the biomass main raw material, the modifier and the water into a reaction kettle, heating to 60 to 100 DEG C for reaction; performing digestive treatment; adding the lubricant, the plasticizer and the crosslinking agent for reaction at 60 to 90 DEG C, then adding the preservative, adding the pH regulator and the auxiliary film-forming agent, mixing, discharging and filtering to obtain the biomass functional adhesive. The biomass functional adhesive has low cost and excellent adhesive performance.

Description

technical field [0001] The invention relates to a starch-based biomass functional adhesive and a preparation method thereof, which is especially used in the field of papermaking. Background technique [0002] With the rapid development of China's economy and the continuous improvement of people's living standards, the requirements for paper quality are also increasing. Therefore, the current cultural and packaging papers are generally surface-coated. Adhesives, pigments and some functional additives are required in the coating process of paper. Among them, the proportion of pigment is the largest, followed by adhesive; the proportion of adhesive in the cost of coating is relatively high. At present, the main types of coating adhesives are: petrochemical synthetic emulsion, coated starch; the price of synthetic emulsion is high, and all raw materials are not renewable; coated starch has the problems of high viscosity and poor rheology, so the amount of coated starch is also...
