ADHESIVE EPOXY COATING, LAYER STRUCTURE OF PLASTIC-COATED METAL AND METHOD OF METAL PAPER REINFORCEMENT Russian patent published in 2008 - IPC C09J163/00 C09D163/00 C09J7/02 B32B7/12 B32B15/08 B32B15/92 

FIELD: chemistry.

SUBSTANCE: invention relates to adhesive epoxy coating of metallic substrate, to layer structure containing such coating and also relates to the method of metal paper reinforcement. Coating is prepared from two-can epoxy composition. The composition contains epoxy material with 25% of total solids and hardening material with 32% of total solids. Epoxy material contains the following components: 3-35% of liquid diglycidyl ethers diphenol-A, 35-60% of solid diglycidyl ethers diphenol-A, 10-30% of epoxy novolac resin and 5-18% of solid butadiene acrylonitrile resin elastic with terminal carboxyl. Hardening material is chosen from a group including up to 0.2% chrome octoate and 4.4'-diaminodiphenylsulfone or its blend. This composition is used as adhesive while deriving layer structure of metallic element/fiber class. Thickness of adhesive coating in layer structure is 0.00254 cm. The method of metallic element reinforcement includes preparation of metallic element surface and application of above mentioned epoxy composition.

EFFECT: thin adhesive coating is derived and economic way of strong adhesion is developed.
