Problems solved by technology

[0003] However, the reinforcing effect of the sheet molded from the composition is poor, and when the reinforced sheet molded from the composition is adhered to the automobile metal panel for a long period of time, the reinforced sheet is usually will be oxidized, resulting in the gradual weakening of the vibration suppression function and sound absorption function of the sheet
Moreover, the reinforced sheet molded from the liquid epoxy resin series shrinks with the vehicle panel through a shrinkage reaction when hardened, or such a sheet falls off during transportation, and when they are applied to the metal panel, It is difficult to adhere to the board with a certain thickness and width, because the hardness of this sheet is low, so it can only be adhered to the board with a thicker thickness, which causes the weight of the vehicle with these sheets to be greatly increased rise
As a result, the quality of the vehicle decreases and its production cost increases

Abstract

The invention provides a reinforced sheet composition for vehicle metal plate and reinforced sheet material formed therefrom, wherein the composition comprises epoxy resin modified by acrylonitrile butadiene, the combination of bisphenol A type epoxide resin and / or carboxyl-terminated butyronitrile modified epoxy resin as adhesive with reinforcing agent, polychloroethylene (PVC) resin or pure PVC resin, mixture formed by adhesion promoter, blowing promoter, latent curing agent and asphaltic resin, the mixture is also mixed by bulking agent, heat stabilizer, coloring agent, reinforcing agent, foaming agent and moisture absorbent.

Description

technical field [0001] The present invention relates to a reinforcing sheet composition for a metal sheet such as an automobile (vehicle) sheet metal, and more particularly, the present invention relates to a metal sheet for a vehicle such as a door, a roof, a hood, a trunk, and a side panel The reinforced damping sheet used. Background technique [0002] Generally, conventional reinforcement sheet compositions for vibration and sound absorption of metal panels such as vehicle metal panels contain butyl rubber or liquid epoxy resin series. [0003] However, the reinforcing effect of the sheet molded from the composition is poor, and when the reinforced sheet molded from the composition is adhered to the automobile metal panel for a long period of time, the reinforced sheet is usually All will be oxidized, resulting in the gradual weakening of the vibration suppression function and sound absorption function of the sheet. Moreover, the reinforced sheet molded from the liquid...
