Problems solved by technology

If the content of phenolic resin is too small, the adhesion ability of alumina will be low; if the content of resin is too high, the spacer will degas a lot during the heating process of the slab, which will affect the bonding quality of zirconium steel

Abstract

The invention belongs to the technical field of separants, and particularly relates to a high temperature resistant separant for a compound board and a preparation method thereof. The separant is formed through blending of aluminum oxide powder and phenolic resin powder and water, wherein the adding amount of phenolic resin powder accounts for 0.01-10% of the weight of aluminum oxide powder. The adherence capability of aluminum oxide can be low if the content of phenolic resin is too low; and the separant can emit a great amount of gas in the heating process of a board green body if the content of resin is too high, so that the binding quality of zirconium steel is affected. The prepared separant is high in dispersion performance, malleability and adherence capability.

Description

technical field [0001] The invention belongs to the technical field of release agents, and in particular relates to a high-temperature-resistant release agent for composite boards and a preparation method thereof. Background technique [0002] With the development of petrochemical, marine construction, pharmaceutical and other industries, the requirements for wear resistance, corrosion resistance, high temperature resistance and structural strength of materials are getting higher and higher. A single metal or even an alloy cannot provide good comprehensive performance, while metal Composite technology largely solves this problem. Composite panels are common titanium-steel composite panels, stainless steel-steel composite panels, copper-steel composite panels, titanium-nickel composite panels, nickel-steel composite panels, copper-aluminum composite panels, nickel-copper composite panels, zirconium-steel composite panels, etc., metal composite panels The advantages of the bo...
