Abstract
The present invention provides an epoxy modified acrylic resin emulsion aqueous anti-rust coating material, which comprises the following raw materials by weight: 60-70 parts of an epoxy modified acrylic resin emulsion, 10-15 parts of iron red, 2-6 parts of talc powder, 1-5 parts of a dispersant, 1-5 parts of an anti-settling agent, 1-5 parts of an infiltration agent, and 10-25 parts of distilled water. According to the present invention, by organically combining the acrylic emulsion coating material and the epoxy resin, the characteristics of high hardness, good sealing property and corrosion resistance of the two materials are completely provided, and the prepared water emulsion type room temperature self-cross-linking emulsion has great application value.
Description
Technical field
The present invention relates to a kind of antirusting paint, more particularly to a kind of epoxy modified acrylic resin emulsion aqueous rust-proof coatings.
Background technology
Coating protection is a kind of using quite varied rust-proofing method; because water paint has relatively low VOC contents, free from extraneous odour, does not burn and low toxin; the trend of existing progressively replacement organic solvent type coatings; most water paint is acrylic emulsion coating on existing market; but traditional acrylic emulsion coating has good weatherability, resistance to water and chemical resistance; but hot sticky cold crisp phenomenon is also easy to produce, anti-after tack, heat resistance be not good.And epoxy resin has, and intensity is high, the characteristic that adhesiveness is good, it is widely used, but its outdoor weathe resistance is poor, and there is shortcoming in above two coating, cause coating not reach corresponding effect, it is impossible to meet the demand of particular customer, cause the vacancy on market.
