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

Abstract
The invention relates to the field of an isolating agent, and particularly relates to a method for obtaining an isolated layer on a base plate and a composite material containing the base plate and the isolated layer. The method for obtaining the isolated layer comprises the steps of spraying the isolating agent onto the base plate, drying and forming the isolated layer on the base plate, and is characterized in the isolating agent contains water, ethyl alcohol and Al 203 powder, wherein the use amount of the water is 300 to 600mL, the use amount of the ethyl alcohol is 300 to 600mL relative to 100g of the Al 203 powder, and the particle size of the Al 203 powder is 20 to 90mum. The isolating agent provided by the invention is capable of being directly spayed on the surface of a composite titanium plate, curing rapidly, and forming an air-drying coating, and the isolation effect is achieved, so that phenomena that adhesion and surface roughness of a titanium-titanium interface do not occur during a process of heating at 800 to 1000 DEG C of constant temperature for 4 to 6 hours and a rolling process of a titanium-steel clad plate, and the yield and production efficiency of the titanium-steel clad plate are improved.
Description
technical field [0001] The invention relates to the field of isolating agents, in particular to a method for obtaining an isolating layer on a substrate and a composite material containing the substrate and the isolating 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 agent...
