A method of obtaining a release agent layer on a substrate and a composite material comprising a substrate and a release agent layer

Abstract

The invention relates to the field of release agents, in particular to a method for obtaining a release agent layer on a substrate and a composite material containing a substrate and a release agent layer prepared by the method. The method for obtaining a release agent layer on a substrate includes coating a release agent on the substrate and drying to form a release agent layer on the substrate, wherein the release agent contains water, alcohol, epoxy resin and Al2O3 powder , wherein relative to 100g of Al2O3 powder, the consumption of the water is 300-600mL, the consumption of the alcohol is 300-600mL, and the consumption of the epoxy resin is 5-15mL. The release agent of the present invention can be directly sprayed online on the surface of the composite titanium plate, can be quickly solidified, and forms a self-drying coating to play the role of isolation, so that the titanium steel composite plate can be neutralized at a constant temperature of 800 ° C to 1000 ° C for 4 to 6 hours. During the rolling process, the phenomenon of adhesion and surface roughness increase will not occur at the titanium-titanium interface, which improves the yield and production efficiency of titanium-steel clad plate processing.

Description

technical field [0001] The invention relates to the field of release agents, in particular to a method for obtaining a release agent layer on a substrate and a composite material containing a substrate and a release agent layer prepared by the method. Background technique [0002] At present, domestic and foreign manufacturers have not reported the use of release agent coating in the process of producing titanium steel composite panels, and they are now keeping secrets from China. In order to save time, save rolling process and surface treatment process, Panzhihua Iron and Steel's titanium-steel clad plate usually adopts such as figure 1 The "sandwich" rolling method shown. In the "sandwich" rolling method, a titanium-titanium interface release agent must be used. The release agent plays a role in the titanium-titanium interface isolation during the rolling process to prevent the titanium-titanium interface from sticking; at the same time, the substances in the release agen...

AI Technical Summary

Problems solved by technology

In the "sandwich" rolling method, a titanium-titanium interface release agent must be used. The release agent plays a role in the titanium-titanium interface isolation during the rolling process to prevent the titanium-titanium interface from sticking; at the same time, the substances in the release agent formula cannot Decomposition reactions occur at high temperatures, or volatile gas substances appear, resulting in poor bonding of the steel-titanium interface and failure of the production of titanium-steel clad panels. Importantly, improper use of release agent will seriously affect the cost and yield of titanium materials
