Water industrial paint based on organosilicon acrylic acid epoxy ester water dispersion and preparation method thereof

Abstract

The present invention provides one kind of water thinned industrial paint based on water dispersed organosilicon epoxy acrylate. The water thinned industrial paint is prepared with water dispersed organosilicon epoxy acrylate, inert antirust pigment, active antirust pigment, nanometer material modified antirust pigment, stuffing, dispersant, wetting agent, thickener, drying agent, mildew inhibitor, preservative, defoaming agent, deionized water and other materials. The water thinned industrial paint with water dispersed organosilicon epoxy acrylate as base material can form coating with the features of high mechanical strength and high anticorrosive performance similar to that of epoxy resin as well as the features of high weather resistance and good decoration performance like acrylate resin. The water thinned industrial paint has convenient use and wide application range.

Description

technical field [0001] The invention relates to water-based industrial paint technology, in particular to a water-based industrial paint based on a silicone acrylate epoxy ester aqueous dispersion and a preparation method thereof. Background technique [0002] According to statistics, the annual corroded and rusted metals in the world account for more than 20% of the annual output, which brings huge economic losses to the world. The annual economic loss caused by metal corrosion in my country accounts for about 4% of the gross national product, exceeding the sum of the losses caused by fire, wind disaster and earthquake. Using paint to prevent metal corrosion is the simplest, most economical and most effective method. However, most of the current metal protective coatings are solvent-based coatings, in which the volatile organic compound content (VOC) is about 50%, which will evaporate during production and construction, causing harm to the environment and human health and ...

Problems solved by technology

There are also some patent announcements in water-based metal coatings, such as the disclosed coatings of patents CN1255935A, CN 1055747A, etc., the formed coating film is either easy to pulverize, has poor weather resistance, or has unsatisfactory adhesion, or cannot be crosslinked at room temperature, resulting in The compactness of the coating film is poor, so the promotion and application status is not good

U.S. Patent US6172159 has prepared a kind of water-based polyester resin, and is directly coated on the water-based paint of metal with it as base material, but this water-based paint can only be used as primer, and is not suitable for as topcoat; Patent US5770657 Although the water-based epoxy-amine curing system provided and the water-based polyurethane system prepared by the patent US6395820 have high comprehensive performance, they are all two-component water-based coatings with a short pot life and inconvenient transportation and construction; therefore, At present, it is still necessary to develop high-performance waterborne metal industrial coatings that can be cured at room temperature with good durability, flash corrosion resistance, excellent wet adhesion, and low water vapor and oxygen transmission rates.
