Problems solved by technology

[0003] The existing solid glue generally uses polyvinyl formal as the main adhesive component, which has low cohesiveness, short storage period, and is easy to gel, but the cost is low, and the existing solid glue mostly uses sodium stearate As an excipient, although potassium hydroxide is used as a pH regulator, since the miscibility with the adhesive components cannot be fundamentally improved, the hardness of the solid glue is likely to increase, the bonding performance and storage stability need to be improved, and it is easy to soften when heated. At the same time, the existing solid glue does not have environmental protection performance, therefore, the present invention proposes a preparation method of polyvinyl alcohol cellulose composite solid glue to solve the problems existing in the prior art

Abstract

The invention discloses a preparation method of a polyvinyl alcohol cellulose composite solid gum. The preparation method comprises the following steps: preparing materials, preparing a base gum, adding an excipient, preparing a mixed reagent, mixing to obtain a colloid, and carrying out cold pressing solidification. The polyvinyl alcohol, glutinous rice starch, gelatin, carboxymethyl cellulose and acrylic resin are used as adhesives; a subsequent neutralizer is matched to neutralize the viscous effect of the concentrated material; cohesiveness is improved, sodium palmitate, agar and betaine are used as excipients; through tests, softening of gelatin is matched; the viscosity is ensured; the hardness of solid gum is reduced, meanwhile, the colloid is better in reset performance, not proneto deformation and stable, the heat resistance and flame retardance of the colloid are effectively improved through the effect of polyurethane matched with a heat stabilizer, the colloid is not proneto softening after being heated, the bonding performance is guaranteed, and in addition, by adding the silver-loaded zirconium hydroxyphosphate nano antibacterial agent and a mildew preventive, bacterium breeding and damage are not prone to occurring.

Description

technical field [0001] The invention relates to the technical field of solid glue preparation, in particular to a preparation method of polyvinyl alcohol cellulose composite solid glue. Background technique [0002] Solid glue is a kind of adhesive with one or more polymer materials such as polyvinyl alcohol (PVA), cellulose, polyvinylpyrrolidone (PVP), acrylic resin, vinyl acetate resin, etc., and fatty acid salt as excipient. Glycerin, propylene glycol, ethylene glycol, etc. are moisturizing antifreeze agents, water is a solvent, react in an environment of 70°C to 90°C, and fill the solid adhesive prepared after cooling; [0003] The existing solid glue generally uses polyvinyl formal as the main adhesive component, which has low cohesiveness, short storage period, and is easy to gel, but the cost is low, and the existing solid glue mostly uses sodium stearate As an excipient, although potassium hydroxide is used as a pH regulator, since the miscibility with the adhesive ...
