Water-based novel special coating for metal fastener anticorrosion, and preparation method thereof

Abstract

The invention discloses a water-based novel special coating for metal fastener anticorrosion, and a preparation method thereof, and belongs to the field of preparation of anticorrosive coatings. The water-based novel special coating for metal fastener anticorrosion mainly comprises water, a steel wetting agent, a metal coupling agent, ammonia water, a dispersing agent, NaNO2, mica oxide powder, ground iron red paste, an antirust emulsion, isomeric alcohol, methanol, a coalescing agent, butyl cellosolve, a stabilizer and a polycarboxylic acid alkali swelling comprehensive thickener. The coatingprovided by the invention has the advantages of fastness in drying and film forming, good corrosion resistance, little harmful smell, non-flammability, low cost, simple process, material environmental protection, good later stability, non-hydrolysis, prolongation of the time of resistance of metal fasteners to weather, rain, salt spray corrosion and other natural factor hazards, enhancement of the rust resistance and corrosion resistance of the metal fasteners, saving of the resource cost, and solving of the technical difficulties of environmental pollution, peeling, rusting, discoloration and the like of traditional metal anticorrosive fastener coatings under the repeated actions of natural factors.

Description

technical field [0001] The invention relates to a metal anti-corrosion paint and a preparation method thereof, in particular to a water-based new metal fastener anti-corrosion special paint and a preparation method thereof. Background technique [0002] With the development of China's economy, the scale of urbanization continues to grow, and the level of urbanization continues to popularize. Steel structures can be seen everywhere in cities, towns and even rural areas. The scale of building bracket fasteners continues to expand, resulting in a huge economic market. Develop a Water-based new metal fastener coatings are the subject of research and development in the coatings industry. The traditional oil-based coating dispersion medium is generally organic solvents (VOC). The organic solvents volatilized from the coating film are toxic and harmful substances, causing harm to the human body and the environment Pollution, due to the continuous implementation of national environm...

[0002] With the development of China's economy, the scale of urbanization continues to grow, and the level of urbanization continues to popularize. Steel structures can be seen everywhere in cities, towns and even rural areas. The scale of building bracket fasteners continues to expand, resulting in a huge economic market. Develop a Water-based new metal fastener coatings are the subject of research and development in the coatings industry. The traditional oil-based coating dispersion medium is generally organic solvents (VOC). The organic solvents volatilized from the coating film are toxic and harmful substances, causing harm to the human body and the environment Pollution, due to the continuous implementation of national environmental protection policies in recent years, polluting enterprises have been gradually eliminated; however, ordinary and common water-based fastener coatings in the market have slow film formation, poor weather resistance, and poor corrosion resistance. Severe corrosion in the sun and rain, discoloration, peeling off, lost the role of protecting the metal
