Single-component room-temperature industrial water crosslinked coating

Abstract

The invention provides a kind of water industrial paint which is single group multi-room cross linking. The paint uses water filming polymer as the base material, the active paint filler and the film surface modifying agent is used as the modification material, and adds in other color fillers, dispersant, antifoam agent, thickener, rot-proof and sterilization agent, filming assistant and water. The paint can form the paint film through cross linking in room temperature, it needn't heating and solidification, it has excellent film rigidity and dirt resisting performance; there can acquire three layers of film only by on time painting; the rot-proof performance is great; the construction of the product is convenient, the applied range is spread, it can upgrades the efficiency of working, saves the cost, reduces the consumption, the product has a good prospect.

Description

technical field [0001] The invention relates to coatings, in particular to a single-component room-temperature crosslinking water-based industrial coating. Background technique [0002] At present, the vast majority of metal protective coatings are solvent-based coatings. The volatile organic compounds (VOC) released during the production and construction process have seriously damaged the environment on which human beings live, and have attracted widespread attention from the international community. As a main environment-friendly coating, water-based coatings have become more and more research hotspots. Since the 1930s, developed countries such as Europe, America, Japan, and Australia have successively developed water-based coatings, and in some fields such as water Towers, storage tanks and other surfaces began to be applied. However, the current application of water-based coatings is mainly concentrated in cathodic electrophoretic paint and ...

Problems solved by technology

U.S. Patent US6172159 has prepared a kind of water-based polyester resin, can make the water-based coating that is directly coated on metal with it, but this water-based coating can only be used as primer, and is not suitable for being used as middle paint and topcoat; U.S. Patent The silicone component in the water-based coating prepared by US4713410 can be enriched on the surface of the coating film due to self-stratification during film formation, but this water-based coating cannot be crosslinked at room temperature and needs to be cured by heating. convenient

Although U.S. Patent No. 5,362,847 has prepared a one-component room-temperature cross-linking water-based coating system by introducing cross-linking groups into the film-forming polymer system, it does not involve a self-delamination coating system that integrates the bottom surface
