Embodiment 1

[0023] The formula of the heat sealant is 1200 grams of light magnesium oxide, 2460 grams of potassium alum, 2140 grams of light calcium carbonate, 300 grams of sodium thiosulfate, 1800 grams of borax, 800 grams of polyvinyl alcohol, 700 grams of sodium benzoate, and 600 grams of starch. According to the above-mentioned method, it is added to the stirring tank in sequence, mixed and stirred uniformly, dried and sieved to obtain a powdery product.

Embodiment 2

[0025] The formula of the heat-sealing agent is 100 grams of light magnesium oxide, 250 grams of potassium alum, 250 grams of light calcium carbonate, 200 grams of borax, 100 grams of polyvinyl alcohol, 50 grams of sodium benzoate, and 50 grams of starch. Mix and stir evenly, dry and sieve to obtain powdery finished product.

Embodiment 3

[0027] The formula of the heat-sealing agent is 150 grams of light magnesium oxide, 200 grams of potassium alum, 250 grams of light calcium carbonate, 50 grams of sodium thiosulfate, 150 grams of borax, 80 grams of polyvinyl alcohol, and 120 grams of sodium benzoate. Add the mixing tank to mix and stir evenly, and then dry and sieve to obtain a powdery product.

Abstract

The invention discloses a process for producing cardboard adhesion starch slurry thermal sealing agent for the raw materials including magnesium hydroxide, potassium alum, calcium carbonate, antiseptic, adhesion promoter, stabilizing agent, wherein the antiseptic is borax, the adhesion promoter is polyvinyl alcohol, the stabilizing agent is sodium benzoate, through agitating, mixing, drying and sieving.

Description

Technical field [0001] The invention relates to a production method of an additive, in particular to a production method of a starch slurry thermal bonding agent for cardboard bonding. Background technique [0002] Cardboard is mainly used to make cartons (boxes) for packaging items, which is convenient for storage and transportation. Ordinary cardboard is generally made of two or more layers of paper bonded together, such as single-sided corrugated paper and composite corrugated paper. The binder used in paperboard is generally starch slurry. In the course of use, people found that the adhesive strength of the cardboard is not enough, and it is easy to regain moisture, which causes the cardboard to shrink and deform, bubble and corrugate. For this reason, people add various additives to the starch slurry, trying to improve the performance of the starch slurry so that it can overcome the above-mentioned problems when it is used in the production of paperboard. But from the curren...
