Method for obtaining release agent layer on base plate and composite material containing base plate and 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 base plate and a composite material containing the base plate and the release agent layer. The method for obtaining the parting agent layer on the base plate comprises coating a release agent on the base plate, and drying to form the parting agent layer on the base plate. The method is characterized in that the release agent comprises water, alcohol, epoxy resin and Al2O3 powder, wherein relative to 100g of Al2O3 powder, the dosage of the water is 300-600mL, the dosage of the alcohol is 300-600mL, and the dosage of the epoxy resin is 5-15mL. The release agent can be online directly sprayed on the surface of a composite titanium board, and can be quickly cured to form a self-drying type coating to achieve a parting effect, so that in a 4-6h constant-temperature process at 800-1000 DEG C and a rolling process of a titanium steel composite board, adhesion and surface roughness increase phenomena of a titanium-titanium interface are avoided, and the yield and the production efficiency for titanium steel composite board processing are improved.

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...

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
