Problems solved by technology

At present, the antirust paints used in the market are generally oily and water-based. Oily antirust paints are easy to use and low in price, but because they contain toxic substances such as nitrite and chromate, they are more harmful to operators, and the country has restricted them. Therefore, there are more and more varieties of water-based antirust paints. Water-based paints can be divided into three types: water-soluble, water-dispersed, and water-diluted. Water-based paints have relatively high requirements for surface cleanliness during construction and materials. If it is not very clean, the effect of water-based paint will be greatly affected

Embodiment 1

[0011] A kind of preparation method of antirust paint of this example, the composition and weight percent of its prescription are: 8% polyvinyl butyral resin, 40% ethanol, 9% phenolic resin, 18% toluene, 1.5% Rust turning agent, 5% talcum powder, 5% iron oxide red, 5% stabilizer, 3.5% zinc oxide are fully stirred and put into a pulverizer for crushing and grinding into powder, and then the powder and 5% water Mix and stir for more than 30 minutes until a thick liquid is formed. The antirust paint prepared in this embodiment is used for coating smooth metal without rust.

Embodiment 2

[0013] A kind of preparation method of antirust paint of this example, the composition and weight percent of its formula are: 9% polyvinyl butyral resin, 35% ethanol, 13% phenolic resin, 14% toluene, 3% Rust turning agent, 7% talcum powder, 8% iron oxide red, 6% stabilizer, 5% zinc oxide are fully stirred and put into a pulverizer for crushing and grinding into powder, and then the powder is mixed with 2% water Mix and stir for more than 30 minutes until a thick liquid is formed. The antirust paint prepared in this example is used for coating metals with rough surface and rust.

[0014] The antirust paint of the present invention has good complexing force with the metal surface, long antirust life, fast drying, convenient use, low cost, high temperature resistance, can be directly sprayed or brushed on the metal surface with embroidery, and can be used at -20°C Can still work as usual in low temperature

Abstract

A method for preparing anti-rust paint comprises the steps of fully stirring, by weight percentage, 7-10% of polyvinyl butyral resin, 30-45% of ethyl alcohol, 8-16% of phenol-formaldehyde resin, 10-20% of toluene, 1.5-3% of rust conversion agent, 4-8% of talc powder, 5-9% of iron oxide red, 4-7% of stabilizer and 3-6% of zinc oxide and placing the raw materials in a pulverizer to pulverize and grind the raw materials into powder, and stirring the powder and 1-5% of water for 30 min or more until thick liquid is formed. The anti-rust paint is good in complexation force with the metal surface and long in anti-rust service life, dries quickly, is convenient to use, low in cost and resistant to high temperature, can be directly sprayed or brushed onto the metal surface having rust, and can still operate as usual at a low temperature of -20 DEG C.

Description

technical field [0001] The invention relates to the field of paints, in particular to a preparation method of an antirust paint. Background technique [0002] Metal rusting is the most common and costly form of corrosion. Antirust work has always been one of the major scientific research topics at home and abroad. People have studied various measures to prevent and inhibit metal corrosion, and antirust with paint is an effective method. Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. At present, the antirust paints used in the market are generally oily and water-based. Oily antirust paints are easy to use and low in price, but because they contain toxic substances such as nitrite and chromate, they are more harmful to operators, and the country has restricted them. Therefore, there are more and more varieties of water-based antirust paints. Water-based paints can be divided into three ...
