Problems solved by technology

[0003] In the process of producing multi-layer fabrics, it is necessary to use composite glue to bond different fabrics. The existing glue has poor initial viscosity and low fastness, which leads to changes in tension during the process of laminating and unloading multi-layer fabrics. Causes foaming at the head of the multi-layer fabric, resulting in lower yield, increased production cost, waste of resources, and does not meet the requirements of environmental protection and high efficiency

Abstract

The invention belongs to the field of adhesive, and particularly discloses a method for preparing glue. The glue comprises 30%-50% of dimethyl carbonate, 20%-40% of polyester components and other auxiliaries. The polyester components are made from toluene, diethylene glycol, adipic acid and 1,4-butanediol. The method has the advantages that the glue prepared by the aid of the method is high in adhesive force, can be used for stickers or can be used for adhering cloth, accordingly, objects are difficult to fall off, and adhered articles can be prevented from deforming; glue systems are stable,and the problems of deterioration of adhesive force, dryness and hardness and the like due to long-term storage can be solved.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a preparation method of glue. Background technique [0002] Glue is an intermediate that connects two materials. It mostly appears as a water agent. It belongs to the fine chemical industry and has a wide variety. It is mainly classified by adhesive, physical form, hardening method and adherend material. The common ones are instant glue, epoxy resin bonding, anaerobic glue, UV glue, hot melt adhesive, pressure sensitive adhesive, latex and so on. [0003] In the process of producing multi-layer fabrics, it is necessary to use composite glue to bond different fabrics. The existing glue has poor initial viscosity and low fastness, which leads to changes in tension during the process of laminating and unloading multi-layer fabrics. It causes foaming at the head of the multi-layer fabric, resulting in reduced yield, increased production cost, waste of resources, and do...
