Problems solved by technology

However, the starch adhesives on the market generally have problems such as low solid content, low initial cohesive force, poor moisture resistance, poor flame retardant effect, poor stability of the glue itself, short storage time, and easy to mold, and some even cause waste paper. Adhesive issues during recycling
Moreover, the traditional production process is complicated, and the production efficiency and product quality cannot be guaranteed.
In the process of improvement, people will add other chemical components to it, but these chemical additives contain more volatile substances of benzene series, which are harmful to the human body

Abstract

The invention relates to the technical field of adhesive manufacturing, in particular to a starch adhesive paste preparation method which comprises the following specific steps: (1) sieving granular components by a 1000 to 1200-mesh sieve one by one; (2) fully mixing and uniformly stirring all the raw materials sieved in the step (1); (3) adding a hydrophilic agent, a gelatinizing agent, a preservative and a catalyst into distilled water, and fully stirring until the components are completely dissolved; (4) adding a mixture obtained in the step (2) into an aqueous solution obtained in the step(3); (5) heating a stirred mixed product to 60-80 DEG C, and continuously stirring in the heat preservation process; and (6) naturally cooling to room temperature to obtain the pasty starch adhesive.According to the starch adhesive paste preparation method, the powder is fully mixed, the auxiliaries are dissolved in the water, and then mixing and paste preparation are performed, so that the mixing sufficiency is greatly improved, the bonding strength of the product is improved, and the starch adhesive paste preparation method is more environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of adhesive production, in particular to a starch adhesive paste preparation method. Background technique [0002] In the prior art, there are many types of adhesives used in paper products, mainly including starch series, polyvinyl alcohol, vinyl acetate emulsion, sodium silicate and the like. At present, the most widely used adhesives are starch series. However, the starch adhesives on the market generally have problems such as low solid content, low initial cohesive force, poor moisture resistance, poor flame retardant effect, poor stability of the glue itself, short storage time, and easy to mold, and some even cause waste paper. Adhesive issues during recycling. Moreover, the traditional production process is complicated, and the production efficiency and product quality cannot be guaranteed. In the process of improvement, people will add other chemical components to it, but these chemical additives ...
