Problems solved by technology

At present, solvent-based adhesives are widely used in production. Since a large amount of organic solvents are volatilized when the solvent-based adhesives are coated and dried, a large amount of solvent emissions will not only cause great pollution to the environment, but also cause different degrees of pollution. Hazardous to the health of production workers

Abstract

The invention discloses an environmentally friendly high speed alumite hot stamping gum and a manufacturing method thereof. The gum comprises, by mass, 15-30% of water-based acrylic emulsion, 15-30% of water-based phenolic emulsion, 0-10% of water-soluble modified abietic resin, 15-30% of water-based polyurethane emulsion, 0-3% of triethylene ammonia, 0-20% of ethanol, 5-30% of deionized water and 0-8% of various necessary auxiliaries. According to the preparation method, components of the gum are stirred and then mixed well, and by adjusting different stirring time and speed, the optimum mixing effect and stability can be achieved. The gum of the invention basically employs water-based materials. Thus, on the basis of meeting the demand of reduced harm to operators and the environmental requirement of reduced VOC (colatile organic compounds) in products, an environmentally friendly gum can be manufactured by means of the functional characteristics of the manufacturing materials and reasonable proportioning. Characterized by moderate brittleness and flexibility, high solid content and low viscosity, the gum of the invention is especially suitable for cases with big surface density, low surface energy, difficulty in transferred bonding, or need for multiple times of high speed hot stamping.

Description

technical field [0001] The invention relates to a method for manufacturing an anodized aluminum hot stamping adhesive for packaging, in particular to an environment-friendly high-speed anodized aluminum hot stamping adhesive and a manufacturing method thereof, belonging to the technical field of adhesive preparation. Background technique [0002] With the rapid development of my country's economy and the improvement of people's living standards, there are higher requirements for the exquisiteness of the packaging of social consumer products such as cigarettes, wine bags, tea and food, and the demand continues to increase. Therefore, electrification The field of aluminum hot stamping has broad development prospects, especially the preparation method of anodized aluminum adhesive is far behind that of foreign countries, and there are dual pressures on the production process that are not environmentally friendly and high cost, which makes anodized The development of hot stamping ...
