Problems solved by technology

[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 are particularly important

Abstract

The invention discloses an adhesive containing modified PVC (polyvinyl chloride) resin for packaging materials. The adhesive comprises an A component and a B component. The adhesive disclosed by the invention has the advantages of reasonable formula design, easily avaliable raw materials, simple production process, easiness in matching with equipment, stable product quality and strong adhesion force, and can be used for improving the physical properties, medium resistance, storage stability and the like in comparison with a traditional adhesive; by adding plant ash after treatment, the damages of water molecules to the adhesive are effectively reduced, the water resistance of the adhesive is greatly improved, and the adhesive has great quick-drying property because the hydrophilicity of the adhesive is reduced; and by adding the modified PVC resin, the viscosity of the adhesive is increased, the flowability of colloid is improved and the adhesion performance of a product is further enhanced.

Description

technical field [0001] The invention mainly relates to a binder, in particular to a binder for packaging materials containing modified PVC resin. 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 packaging materials containing modified PVC resin in order to remedy the defects of the prior art. [0004] The present invention ...
