Agricultural machine environment-friendly anti-rust coating and preparation method of same

Abstract

The invention discloses an agricultural machine environment-friendly anti-rust coating which includes, by weight, 40-50 parts of acrylic resin, 3-5 parts of antimonous oxide, 8-10 parts of polyethylene glycol, 7-9 parts of a composite filler, 6-10 parts of a processing aid, 0.4-0.8 parts of polydimethylsiloxane, 0.6-0.8 parts of SiO2, 5-9 parts of a sodium salt additive, 6-10 parts of a composite synergist, 4-6 parts of EDTA, 3-7 parts of glycerol and 15-25 parts of deionized water. The anti-rust coating has strong adhesive force on metal products and has excellent anti-rust protective effect on the metal products, can be used repeatedly, is free of discharge of waste liquid and acid fog which causes environment pollution, is free of burning skin during use, is irritation-free and damage-free on human body and is easy to use. The raw materials are low in cost and easy to obtain. The preparation method has simple processes, high practical value and excellent application prospect.

Description

technical field [0001] The invention relates to the technical field of mechanical protection, in particular to an environmentally friendly antirust coating for agricultural machinery and a preparation method thereof. Background technique [0002] The anti-rust and anti-corrosion protection products currently used in the field of agricultural machinery and vehicles are roughly divided into three types: paint protection wax, inner cavity anti-rust wax and chassis anti-rust armor wax. The paint protective wax and inner cavity antirust wax mostly use petroleum wax as the film-forming component. Chassis armor wax uses asphalt as a film-forming component (first generation), or olefin polymer and elastomer rubber as a film-forming component (second and third generations), or composite polymer resin as a film-forming component ( Fourth Generation).

AI Technical Summary

Problems solved by technology

[0003] The main material of paraffin-based paint protective wax and agricultural machinery inner cavity anti-rust wax is petroleum wax with a crystal structure. After the film is formed, the film layer is loose and dull, with low flexibility and hardness. The melting point is low, and it is easy to melt and lose and become thinner after being exposed to the sun in summer. When used in severe cold areas in winter, the film layer becomes hard, brittle, cracked or falls off in pieces, which cannot achieve an ideal protective effect.

Therefore, the anti-rust protection effect of some brands of agricultural machinery is not good, and it is difficult to meet the anti-corrosion requirements of more than ten years

[0004] The first-generation "asphalt-based oil-based paint" and the second-generation "rubber-based oil-based paint" in the traditional agricultural machinery chassis armor wax are all non-environmental-friendly, and the diluent is mostly toluene, and toluene is a harmful substance to the human body. Highly toxic ingredients, and the film layer formed after construction is very hard, easy to crack, and the sound insulation effect is also very general, so it has been gradually eliminated from the market

The third generation of "polymer water-based paint" is environmentally friendly, but because the construction is greatly affected by temperature and humidity, it takes a long time and is not welcomed by car owners.

At present, the domestic fourth-generation "composite polymer resin" quick-drying chassis armor paint genuine products are high in price and low in profit, and very few people use them. Most of them are counterfeit and inferior products, which harm car owners.

The defect of this composite polymer resin "quick-drying chassis armor paint" is a multi-component material grafted entirely from polymer synthetic materials, which still retains its own performance defects. At the same time, due to its relatively large molecular weight, high carbon number, and low temperature The performance is not very ideal. After a long time of high and low temperature alternating action, the low temperature hardness increases, becomes brittle, and the adhesion becomes poor. After a long time, it is easy to fall off
