Abstract

The invention provides an environmentally friendly galvanized metal repair agent and a preparation method thereof. The environmentally friendly galvanized metal repair agent is prepared from, by mass, 15-20 parts of attapulgite, 20-30 parts of amino clay, 1-7 parts of aluminum distearate, 4-8 parts of ceramic ultrafine powder, 4-15 parts of composite nano-powder, 3-6 parts of sodium potassium silicate, 3-5 parts of gamma-thionyl trimethoxysilane, 2-6 parts of gamma-aminopropyl triethoxysilane, 12-18 parts of waterborne polyurethane, and 3-5 parts of poly trimethoxysilane. The preparation method of the environmentally friendly galvanized metal repair agent comprises the steps of mixing, heating, kneading, grinding and the like, the prepared environmentally friendly galvanized metal repair agent has the advantages of being good in abrasive resistance, anti-corrosion and lubricating, high in metal bonding strength, and long in service life.

Description

technical field [0001] The invention relates to the technical field of metal restoration agents, in particular to an environment-friendly galvanized metal restoration agent and a preparation method thereof. Background technique [0002] Metal repair agent refers to an industrial auxiliary product that applies adhesives or polymer composite materials added with special materials (aggregate) to the surface of the metal parts to be repaired to repair the metal or endow the metal surface with special functions. With the development of industrial modernization, the requirements for the safe and continuous operation of various mechanical equipment are getting higher and higher, and the long-term operation of equipment under harsh environmental conditions such as high temperature, high pressure, impact, and corrosion often causes the entire part to be damaged due to local damage. Scrapping will eventually lead to equipment shutdown. In recent years, industrial enterprises hope to a...
