Problems solved by technology

[0004]At present, most of the epoxy resin anti-corrosion coatings with rust on the market are of a single type (penetration type, stable type or conversion type), with limited rust removal ability and corrosion resistance. , environmental protection and construction performance still need to be improved; the commercially available epoxy anti-corrosion coating with rust with tannic acid as penetrating agent has a fragile texture after film formation, and its promotion is restricted; ) conditions, these coatings often cause a decrease in adhesion due to water vapor adsorption on the steel substrate, affecting construction

Embodiment 1~ Embodiment 4

[0045] The preparation technology of epoxy band rust anticorrosion coating in embodiment 1~embodiment 4 is as follows:

[0046] Weigh the ingredients contained in component A as shown in Table 1, first put epoxy resin E51, ethylene glycol butyl ether, zirconate coupling agent, and silane coupling agent into the mixer in sequence, and mix at 800~1000 rpm Stir for 10 min, and add zinc phosphate, sericite powder, aluminum tripolyphosphate, and red iron oxide in sequence under stirring, and continue stirring for 10 min to obtain component A.

[0047] Weigh the components contained in component B as shown in Table 1, first put the amino-terminated epoxy-amine adduct and n-butanol into the mixer in sequence, stir at 800~1000 rpm for 10 min, and in the stirring state Add tannic acid, phytic acid, and ethanol in turn, and continue stirring for 10 min to obtain component B.

[0048] When in use, mix component A and component B according to the weight ratio of 4:1, and stir evenly...

Abstract

The invention provides an epoxy anticorrosion decoration paint. The epoxy anticorrosion decoration paint is characterized by being prepared by mixing a component A and a component B according to the weight ratio of 4:1, wherein the component A contains 30-50% of low molecular weight epoxy resin, 5-10% of zinc phosphate, 5-10% of packing, 5-10% of aluminium triphosphate, 20-30% of iron oxide red, 0.2-0.5% of tetra-n-propyl zirconate, 0.1-0.3% of silane coupling agent and 5-20% of butyl cellosolve, and the component B contains 30-50% of amino-terminated epoxy-amine affixture, 0.1-0.5% of penetrant, 0.1-0.5% of phytic acid, 30-48% of ethanol and 30-48% of n-butyl alcohol. The paint has excellent corrosion resistance, strong base material adhesion, good flexibility and shock resistance, high solid content, low viscosity, strong tolerance to environment humidity and strong construction adaptability.

Description

technical field [0001] The invention belongs to the technical field of anticorrosion coating for iron and steel materials, and in particular relates to an epoxy anticorrosion coating with rust. Background technique [0002] One of the most commonly used anticorrosion methods for iron and steel materials is to coat the surface with heavy-duty anti-corrosion coatings, but this type of coating has relatively high requirements for the surface treatment of steel substrates, and generally requires spraying (shot, sand) and other derusting treatments to achieve Sa2. Level 5 requirement. Rust coating is a new development trend of anti-corrosion coatings. Its advantage is that it can be directly coated on the steel surface with incomplete or incomplete rust removal. According to its mechanism of action, it can be roughly divided into penetrating type, stable type and Three types of conversion. The penetrating type mainly uses the highly penetrating resin as the paint base, with th...
