AI Technical Summary

Problems solved by technology

At present, some non-marking adhesives on the market still have more restrictions in terms of application range and environment, such as can only be used on smooth surfaces, have poor oil and moisture resistance, can only be used once or claim to be multiple times In fact, there are various short boards such as short stickiness maintenance time and poor load-bearing bonding effect. Therefore, it is necessary to develop a non-marking adhesive that can break through the current use restrictions and have more complete and optimized functions to adapt to more and more varieties. and complex usage requirements

Abstract

The invention discloses a moisture-proof, non-marking and movable high-strength viscose glue. The viscous glue is prepared from cyanate ester resin, butyl rubber, chlorobutyl rubber, diphenylmethane diisocyanate, toluene diisocyanate, 2-bis(hydroxymethyl)butyric acid, trimethylolpropane, 1,2- propylene glycol, dodecanedioic acid, sebacic acid, nanometer calcium carbonate and aminotriethanol. The invention also discloses a preparation method of the moisture-proof, non-marking and movable high-strength viscose glue.

Description

technical field [0001] The invention belongs to the field of viscose manufacture, and more specifically, the invention relates to a moisture-proof traceless removable high-strength viscose and a preparation method thereof. Background technique [0002] With the development of the times and people's pursuit of a higher quality of life, a non-marking adhesive that is faster and safer than hot melt adhesives, and cleaner and more environmentally friendly than liquid adhesives has been more and more widely used.
