example 1

[0032]In parts by weight, 30 parts of rice husk, 3 parts of biogas slurry, 2 parts of sucrose, and 50 parts of water were placed in a fermentation tank, and mixed and fermented for 5 days at a temperature of 35 °C and a rotation speed of 200 r / min, followed by Adding a sodium hydroxide solution with a mass fraction of 30% to the mixing tank to adjust the pH to 9.6 to obtain a fermentation mixture, then filtering the fermentation mixture to obtain a filter residue, then freezing the filter residue in liquid nitrogen to obtain a frozen filter residue, and then Place the frozen filter residue in a ball mill and pass through a 280-mesh sieve to obtain a ball mill, then wash the ball mill with glacial acetic acid until the washing liquid is neutral, then place the washed ball mill in an oven at a temperature of 110°C Under the same conditions, dry to constant weight to obtain dry ball abrasive, then put the dry ball abrasive in a carbonization furnace, and fill the furnace with nitr...

example 2

[0034] Ball mill the medical stone and pass through a 100-mesh sieve to obtain medical stone powder; put the medical stone powder and urea solution with a mass fraction of 20% in a beaker at a mass ratio of 1:30, then place the beaker in an ultrasonic disperser, and Under the condition of frequency of 75kHz, after mixing with ultrasound for 60min, filter and filter the cake, then place the filter cake in an oven, and dry it to constant weight at a temperature of 110°C to obtain pretreated medical stone powder; calculated in parts by weight , put 30 parts of pretreated medical stone powder, 20 parts of carbomer 934, and 40 parts of ethanol with a mass fraction of 50% in a single-necked flask, and stir and mix for 60 minutes under the condition of a rotating speed of 500r / min to obtain a mixed slurry, then Put the mixed slurry in a rotary evaporator, and concentrate under reduced pressure for 60 minutes at a temperature of 70°C to obtain a concentrated solution, then place the co...

Abstract

The invention discloses a metal surface anti-corrosive paint, and belongs to the technical field of building material. A preparation method comprises following steps: rice husk, biogas slurry, cane sugar, and water are mixed for fermentation, a sodium hydroxide solution is added to adjust the pH value, filtering, refrigeration, ball milling, sieving, washing, drying, and nitrogen filling thermal insulation carbonization are carried out so as to obtain a modified filling material; Chinese medical stone is subjected to ball milling and sieving so as to obtain Chinese medical stone powder; the Chinese medical stone powder and a urea solution are mixed, and are subjected to ultrasonic treatment, filtering, and drying so as to obtain pre-treated Chinese medical stone powder; the pre-treated Chinese medical stone powder, carbomer 934, and ethanol are mixed, pressure reduction condensation and drying are carried out so as to obtain a modified additive; epoxy resin, a diluent, a curing agent,the modified filling material, the modified additive, a silane coupling agent, nanometer zinc oxide, phosphatide, ephedrine, polyisocyanate, and a mineral filler are stirred and mixed so as to obtainthe metal surface anti-corrosive paint. The metal surface anti-corrosive paint possesses excellent corrosion resistance.

Description

technical field [0001] The invention discloses an anticorrosion coating for metal surfaces, which belongs to the technical field of building materials. Background technique [0002] With the rapid development of modern industry, the anti-corrosion of metal surfaces has been paid more and more attention by all walks of life. It is an economical and effective method to use paint to coat anti-corrosion. For industrial and mining enterprises, the huge economic losses caused by metal corrosion are incalculable. It can be seen how important the protection against corrosion is. There are many ways to prevent metal corrosion, such as the use of electroplating and cathodic protection, which cause emission pollution and are not conducive to environmental protection; there is also the use of corrosion-resistant alloys, which play an anti-corrosion role, but the project cost is high. It has been proved by practice that the protection of the coating layer is the most effective and most ...
