Solvent-free cardanol epoxy heavy-duty antiseptic paint and method for producing the same

Abstract

The invention provides a solvent-free cardanol epoxy heavy anticorrosive paint, comprising 40-60 wt% of butyronitrile modified epoxy; 20-40 wt % of cardanol epoxy firming agent; 5-20 wt % of reactive diluent; 10-30 wt % of color filler and 5-8 wt% of additive. The invention further provides a preparation method of the solvent-free cardanol epoxy heavy anticorrosive paint, comprising the following steps: evenly mixing, stirring and milling the butyronitrile modified epoxy, the reactive diluent, the color filler and the additive so as to obtain component A according to mixture ratio of the solvent-free cardanol epoxy heavy anticorrosive paint; taking the cardanol epoxy firming agent as component B; and evenly mixing and stirring the component A and comment B when in use. The invention has the advantages of good high-temperature resistance property, good oil resistant property, strong chemicals corrosion resistance property, good construction matching property, good matching use property with the cathode protector of a storage tank, stable curing reaction in low-temperature moist environment, long service life, outstanding paint film insulating property, no environmental pollution, no irritating gas as well as simple, safe, environmental protection and healthy use.

Description

technical field [0001] The invention relates to a solvent-free cardanol epoxy heavy-duty anticorrosion paint and a preparation method thereof. Background technique [0002] The existing epoxy resin used for anti-corrosion coatings has many disadvantages as a film-forming agent: the paint film is brittle, and its temperature resistance and ultraviolet resistance are poor. Epoxy resin curing agent is highly toxic, and after cross-linking with epoxy, the pot life is short, the proportion range is narrow, and some properties are not satisfactory (large internal stress, oil resistance, water resistance, heat resistance, weather resistance, etc.); use A large number of organic solvent diluents can adjust viscosity and pollute the environment. Construction in a closed system is likely to cause "flash explosion" and cause personal safety and property damage. The above drawbacks are difficult to meet the requirements of heavy-duty anti-corrosion coatings in various modern applicati...

Problems solved by technology

[0002] The existing epoxy resin used for anti-corrosion coatings has many disadvantages as a film-forming agent: the paint film is brittle, and its temperature resistance and ultraviolet resistance are poor. Epoxy resin curing agent is highly toxic, and after cross-linking with epoxy, the pot life is short, the proportion range is narrow, and some properties are not satisfactory (large internal stress, oil resistance, water resistance, heat resistance, weather resistance, etc.); use A large amount of organic solvent diluent, adjust the viscosity, pollute the environment

Construction in a closed system is likely to cause "flash explosion" and cause personal safety and property damage

The above disadvantages are difficult to meet the requirements of heavy-duty anti-corrosion coatings in various modern application fields, especially the heavy-duty anti-corrosion coatings for closed space systems (various oil storage tanks, pipelines, cabins, submarines, containers, etc.)
