Abstract

The invention discloses an organic-inorganic composite coating material, a preparation method, and a method for preparing a wear-resistant coating by using the organic-inorganic composite coating material. The preparation method of the organic-inorganic composite coating material comprises the following steps: taking tetraethoxysilane as a precursor, and adding a silane coupling agent to prepare ahybrid silica sol; and reacting the hybrid silica sol with a titanium dioxide sol to obtain the organic-inorganic composite coating material. A matrix is pretreated, then is impregnated in the organic-inorganic composite coating material for 1-2 min, then is pulled out at a constant speed and stands for 2-4 h, and then the coating material is dried to form the wear-resistant coating on the matrix. The prepared organic-inorganic composite coating material can form the flat and compact coating on the surface of the matrix, so the wear resistance of the matrix is remarkably improved; the preparation method is simple, the production efficiency is high, and the organic-inorganic composite coating material has wide application prospects in the field of explosion-proof materials.

Description

technical field [0001] The invention relates to the technical field of wear-resistant coating materials, in particular to an organic-inorganic composite coating material, a preparation method and a method for preparing a wear-resistant coating using the same. Background technique [0002] Explosion-proof tools are collectively referred to as safety tools and non-sparking tools internationally. They are made of non-steel materials and are hand-held tools used in flammable and explosive places. At present, the materials of explosion-proof tools produced, sold and distributed in China are mainly divided into two categories: aluminum-copper alloy (commonly known as aluminum bronze) and beryllium bronze alloy (commonly known as beryllium copper). These two alloys have very good thermal conductivity and electrical conductivity. No sparks will be generated under the condition of impact and friction, and it is suitable for manufacturing explosion-proof tools used in flammable, explo...
