Abstract

The invention provides an enhancement paster matrix, an enhance paster and a steel plate composite material. The enhancement paster matrix, which contains epoxy resin, nitrile rubber, a filling material and a curing agent, is characterized in that the enhance paster matrix also contains adhesion promoting resin and the adhesion promoting resin contains styrene-ethene / butylene-styrol copolymer or styrene-butadiene-styrene copolymer. The enhancement paster prepared by the enhancement paster matrix has a high adhesion on the surface of steel plates, and especially antirust oil on the surface of steel plates has no impact on the adhesion.

Description

technical field [0001] The invention belongs to the field of automobile steel plate reinforcement, and in particular relates to a reinforcement patch matrix, a reinforcement patch and a steel plate composite material. Background technique [0002] At present, the world's climate continues to deteriorate, and the greenhouse effect is becoming more and more serious. As a major source of greenhouse gases, the emission of automobile exhaust has attracted more and more attention. [0003] In order to reduce the emission of automobile exhaust, reduce the weight of the vehicle body and reduce the average load of the automobile, it has become an effective method for energy saving and emission reduction. In actual automobile manufacturing, the weight of the body is generally reduced by reducing the thickness of the steel plate of the body to achieve the purpose of energy saving and consumption reduction. However, while reducing the thickness of the steel plate of the vehicle body, ...
