Abstract
The invention discloses an adhesion agent for a double-component packaging material. The adhesion agent consists of two components A and B. The adhesion agent has the characteristics of reasonability in formula design, easily obtained raw materials, simplicity in production technology, easiness in equipment matching, stability in product quality and strong adhesion, and the physical performance, medium resistance, storage stability and the like are all improved as compared with a conventional adhesion agent; through adding the treated plant ash, the damage of water molecules to the adhesion agent is effectively reduced, so that the water resistance of the adhesion agent is greatly improved; the adhesive hydrophilic performance is reduced, so that the adhesion agent has good quick drying characteristic; and through adding an improved polyvinyl chloride resin, the adhesiveness of the adhesion agent is increased, the fluidity of the adhesive is improved, and the adhesion property of the product is further increased.
Description
technical field [0001] The invention mainly relates to an adhesive, in particular to an adhesive for two-component packaging materials. Background technique [0002] Packaging adhesives are produced and developed on the basis of the rapid development of the packaging industry. The performance and quality of packaging adhesives directly affect the packaging effect and quality. At present, packaging adhesives generally have poor heat resistance. Poor, poor cold resistance, poor storage stability, poor medium resistance and other shortcomings, in order to overcome these shortcomings of traditional binders, a new, high-performance binder is invented for people's daily life, production and development appear to be particularly important. Contents of the invention [0003] The object of the present invention is to provide a binder for two-component packaging materials in order to remedy the defects of the prior art. [0004] The present invention is achieved through the follow...
