Abstract

The invention relates to the technical field of adhesives, and more specifically, the invention relates to a thermally vulcanized adhesive. The first aspect of the present invention provides a thermal vulcanization adhesive, calculated by weight percentage, the thermal vulcanization adhesive at least includes 5-15% phenolic resin, 5-15% film forming agent, 0.5-5% absorbent Acid agent, 5-10% adhesion promoter, balance solvent.

Description

Technical field[0001]The present invention relates to the field of adhesives, and more particularly, the present invention relates to a thermal vulcanized adhesive.Background technique[0002]Due to frequent earthquakes in Yunnan, Sichuan and other regions, these areas must consider the demand for earthquake resistance in architectural design. The current mainstream mode is to add seismic support. The obsolete support is bonded to the multi-layer steel plate and rubber, and the steel sheet is used as a rubber support. It has changed the characteristics of the vertical stiffness of the rubber body, so that it can reduce the horizontal seismic effect and to withstand Large vertical load. At present, the most demanding evaluation means for isolation support is extreme shear displacement, and the specific mode is to apply a large load vertically, and then perform horizontal shear dismissal test. At present, the national standard is that the support is not damaged during 350%, and Japan ha...
