Problems solved by technology

[0003] Although the current two-component epoxy resin glue is rigid and brittle, it has good bonding strength and is currently a good woodworking glue. However, this oily and solvent-based epoxy resin is often due to the addition of active diluents. And the solvent and the curing agent used are inevitably non-toxic and safe for construction. Cleaning the sizing equipment is also a very troublesome thing.

Abstract

Belonging to the technical field of chemical adhesives, the invention relates to an environment-friendly high performance waterborne epoxy woodworking glue. Specifically, a component A is composed of emulsified epoxy resin, a modifier, a thickener and water; and a component B is a modified amine curing agent. All the used epoxy resin, modifier, thickener and modified amine curing agent are non-toxic or basically non-toxic. The material has the characteristics of high bonding strength, good tear resistance, good flexibility, good permeability and fast film forming speed. The fastest dry curing can be achieved within 40min-1h (depending on humidity) at 25DEG C. The glue can be applied to brush coating at -5DEG C, and the highest strength can be reached in 7 days. The glue is waterborne, green and environment-friendly, can be diluted with water, and is convenient for gluing. Gluing machines and tools can be washed with water. The glue can be used for bonding of wood, cement boards, PVC, expanded polystyrene and other materials.

Description

technical field [0001] The invention belongs to the technical field of chemical adhesives, and in particular relates to a modified water-based epoxy resin adhesive which is green, environmentally friendly, dilutable with water, has good bonding strength, good flexibility, good permeability and good tear resistance . Background technique [0002] At present, many woodworking glues are toxic. In the synthetic glue process, the addition of formaldehyde is necessary to ensure the performance of the glue, but it is very difficult to completely remove unreacted formaldehyde in the post-treatment. However, the residual formaldehyde inside the glue film It will be released slowly and cause great harm to the human body. [0003] Although the current two-component epoxy resin glue is rigid and brittle, it has good bonding strength and is currently a good woodworking glue. However, this oily and solvent-based epoxy resin is often due to the addition of active diluents. And the solven...
