Abstract

The invention provides a low-temperature setting environment-friendly water-based flocking adhesive which consists of the following components in parts by weight: 30 to 40 parts of modified glutinous rice glue, 5 to 8 parts of citric acid, 3 to 5 parts of thickener, 1 to 3 parts of emulsifier, 1 to 3 parts of antifoaming agent, 3 to 5 parts of preservative, 2 to 4 parts of D-glucose, 3 to 5 parts of silane coupling agent and 8 to 10 parts of deionized water. A preparation method of the improved glutinous rice glue comprises: after uniformly mixing glutinous rice flour, potato starch and water, carrying out high-temperature gelatinization, compound enzyme enzymolysis and enzyme denaturing; cooling to a temperature of 50 to 60 DEG C; then sequentially adding organic improved montmorillonite, chitosan and beta-cyclodextrin. The flocking adhesive provided by the invention uses the natural environment-friendly glutinous rice glue as a main ingredient, has the advantages of high environment-friendliness, low-temperature setting and good weather resistance and meanwhile, solves the problems of low cohesiveness, poor antibacterial property and easiness for generating cracks of common glutinous rice glue.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a flocking adhesive, in particular to a low-temperature curing environment-friendly water-based flocking adhesive. Background technique [0002] Electrostatic flocking is prepared by planting electro-treated short fibers on the surface of the substrate coated with adhesive in a high-voltage electrostatic field, and then pre-baking, baking and other processes. As a surface processing technology, electrostatic flocking has its unique advantages. It can be flocked on various three-dimensional and non-three-dimensional substrates such as fabric, paper, plastic, rubber, wood, glass, metal and ceramics. It has been widely used in Automobiles, stationery, packaging, decoration, instruments and meters and many other industries, and have the functions of wear resistance, lubrication, sealing, sound insulation, heat insulation, anti-scalding, anti-corrosion and anti-fouling, ...
