Problems solved by technology

Due to the large filler particles, the formed coating has poor compactness and thick paint film, so it cannot be used for the inner wall of the pipeline, and can only be used for ballast water tanks and other equipment of ships.

Abstract

An anticorrosion and antiwear ceramic paint is prepared from epoxy resin (28.5-35 wt.portions), dibutyl phthalate (3.75-6), mixed solvent of xyrene and n-butyl ester (20-24), gas-phase SiO2 (0.5-1) and ceramic powder (38-45) which contains TiO2 (3-6.3), Al2O3 (11.7-20) and Si3N4 (16-20.45). The weight ratio of main component to slidifying agent is (14.5-17):1. It can be directly applied to the surfaces of metal, glass fibre, plastic, or concrete with the advantages of high antiwear performance and adhesion, and thin and compact coated layer.

Description

(1) Technical field [0001] The invention relates to an anti-corrosion and wear-resistant coating mainly composed of epoxy resin and ceramic powder, and the ceramic powder is made of TiO 2 、Al 2 o 3 and Si 3 N 4 Composition, especially the heavy-duty anti-corrosion and wear-resistant coating for the inner wall of the pipeline. (2) Background technology [0002] The methods of improving the wear resistance of coatings are divided into two categories: one is to improve the film-forming substances; the other is to add wear-resistant fillers to the coatings. The method of adding wear-resistant fillers in coatings, for example: Hahalina et al. of the former Soviet Union disclosed a modified epoxy resin in "Wear-resistant Composite Coating" (Russian Patent SU 1742284 A1 АНТИΦРИКЦИННАЯ КОМПОЗИЦИЯ ДЛЯПОКРЬIТИЯ УЗЛОТ РЕНИЯ СКОЛЬЖEНИЯ) It is a film-forming substance, graphite, acid-resistant powder and quartz powder are used as fillers, and it is a wear-resistant coating cured wit...
