Problems solved by technology

With the improvement of living standards, consumers' awareness of quality and environmental protection is increasing, and the human body has put forward new requirements for adhesives that are environmentally friendly and low-toxic. The production of low-toxic, non-polluting environmentally friendly glue has become a development trend. However, many existing Glue, not only insufficient in environmental protection, but also weak in bonding strength, easy to detach

Abstract

The invention discloses high-performance strong glue. The high-performance strong glue is prepared from the following components: modified cassava starch, polyvinyl alcohol, vinyl acetate, nano-diatomite, a yam and wolfberry mixed extracting solution, lauryl methacrylate, sodium lignosulfonate, butyl acrylate, propolis and lanolin. The high-performance strong glue is environment-friendly and has excellent comprehensive performance; the high-performance strong glue can generate very low stress to a contact object during cold-hot impact cycle at -12 to 180 DEG C after being cured, and can still resist destructive power above 60N after being subjected to 200 cold-hot impact cycles at -12 to 180 DEG C; and water resistance and heat resistance are excellent, fast bonding is realized, the falling is avoided, and the cementing strength is high.

Description

technical field [0001] The invention relates to the field of glue, in particular to a high-performance super glue. Background technique [0002] There are many types of glue, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc. according to the application method; according to the application object, it can be divided into structural type, non-configuration or special glue; the joint form can be divided into water-soluble type. , water-emulsion type, solvent-type and various solid-state types, etc. With the improvement of living standards, consumers' awareness of quality and environmental protection is increasing, and the human body has put forward new requirements for adhesives that are environmentally friendly and low-toxic. The production of low-toxic, non-polluting environmentally friendly glue has become a development trend. However, many existing Glue is not only insufficient in environmental protecti...
