Composition of surface protective agent for metal mold

Abstract

The invention relates to a composition of a surface protective agent for a metal mold. Raw materials in the composition respectively comprise the following components in percentage by weight: 1-5% ofa waterborne epoxy resin, 1-5% of nickel sulfate, 2-4% of nickel ammonium thiocyanate, 5-13% of benzotriazole, 15-20% of sodium isooctanoate, 8-10% of ethyl acetate and 5-7% of mixed tung oil. The product prepared by the method is wide in raw material sources, low in cost, fast in drying speed, has no fluorine and chlorine elements in the components, is safe and environment-friendly, and does notaffect the conductivity, insulation and weldability of coated parts, so that the product is suitable for protecting the surface of the metal mold. The preparation method provided by the technical scheme is simple in process, convenient and practical, and suitable for popularization and application.

Description

technical field [0001] The invention discloses a formula of a surface protective agent for a metal mould. Background technique [0002] After the metal is corroded, its shape, color, electrical properties and mechanical properties will change, which will cause equipment damage, pipeline leakage, product pollution and other accidents. Therefore, the surface of the metal needs to be protected or treated. At present, The technical solution used to solve the above problems is generally to coat the metal surface with paint or electroplating, so as to achieve the protective effect, but the main problems of coating the metal surface with paint or electroplating are: first, the adhesion of the paint is poor, and the time is long It is easy to fall off; the second is that coating or electroplating will cause environmental pollution problems, which cannot meet the needs of the product. Therefore, a protective agent for the surface of a metal mold with a wide range of raw materials, lo...
