Problems solved by technology

Polyvinyl formal solid glue sticks have the advantages of low cost and fast drying speed, but the residual free formaldehyde in polyvinyl formal solid glue greatly reduces the environmental protection performance; and artificially synthesized polyvinyl pyrrolidone is used as glue Although the solid glue stick prepared by the polyvinylpyrrolidone has the characteristics of strong adhesion, smooth coating, safety and non-toxicity, it also has the disadvantage of reducing the K value and reducing the viscosity due to the degradation of polyvinylpyrrolidone.

Abstract

The invention relates to an environment-friendly degradable plant solid glue stick which comprises the following components in percentage by weight: 30-60% of deionized water; 10 to 25% of hydroxypropyl starch ether; 5 to 10% of oligosaccharide; 17 to 40 percent of 28 percent polyvinylpyrrolidone; 4-10% of glycerin; 3-10% of stearic acid; 0.4 to 2.5 percent of sodium hydroxide; 0.1-1% of a preservative; and 0.1%-0.5% of a defoaming agent. Fatty acid salt is used as an excipient, glycerin is used as a humectant, raw materials are easy to obtain, the production cost is low, biodegradable plant starch hydroxypropyl starch ether and oligosaccharide are used as adhesives, the prepared solid glue stick has the original characteristics of a common solid glue stick, and the solid glue stick is easy and convenient to use, high in initial stickiness, large in bonding strength, good in adhesive force and capable of being used for a long time. The paint has the advantages of high drying speed, long adhesion time, no cracking, no shedding, safety, environmental protection and no harm to human bodies, is a novel environment-friendly product, accords with novel European and American stringent environmental protection laws and regulations, improves the competitiveness of the product, and undertakes the social responsibility of environmental protection.

Description

technical field [0001] The invention relates to an environment-friendly degradable plant solid glue stick and a preparation method thereof. Background technique [0002] Solid glue is a new product in adhesives. Its main features are: easy to obtain raw materials, simple production, long shelf life, easy to carry, easy to use, and firm bonding. Solid glue can be used to bond various paper and paper products, suitable for office workers, accountants, secretarial staff, teachers, students and related personnel. [0003] Most of the solid glue stick products on the existing market use modified polyvinyl alcohol, polyvinylpyrrolidone, etc. as adhesives, and add modifiers, excipients, and wetting agents to prepare. Polyvinyl formal solid glue sticks have the advantages of low cost and fast drying speed, but the residual free formaldehyde in polyvinyl formal solid glue greatly reduces the environmental protection performance; and artificially synthesized polyvinyl pyrrolidone is...
