Efficient anionic water-based inorganic environmental protection coating

Abstract

The invention relates to efficient anion water-based inorganic environmental protection coating, characterized by being prepared from the following components in parts by weight: 15-25 parts of silicate aqueous solution, 10-20 parts of silica sol, 5-10 parts of polyvinyl alcohol, 10-15 parts of rare earth oxide, 10-15 parts of tourmaline powder, 10-20 parts of deionized water, 4-5 parts of silanecoupling agent, 1-2 parts of defoamer, 0.5-1 part of flatting agent, 3-5 parts of nano zinc oxide dispersion liquid, 10-20 parts of zinc powder and 2-5 parts of talcum powder. A film forming matter ofthe efficient anionic water-based inorganic environmental protection coating is inorganic silicate, and is environmentally friendly and free of VOC; based on the valence alternation property of unpaired electron of rare earth element 4f track, the electrolytic capability of tourmaline electric field on water molecules in air is enhanced, and anion is efficiently produced; the addition of nano zinc oxide improves the capability of the coating decomposing formaldehyde and purifying air; compared with similar products on the market, the coating is strong in environmental protection and formaldehyde removal capabilities, has good adhesion and corrosion resistance on a metal substrate, and fills the blank of anion coatings on the metal substrate.

Description

technical field [0001] The invention belongs to the technical field of environmental protection coatings, in particular to a water-based, anti-corrosion and environmental protection coating for metal substrates that can efficiently release negative ions. Background technique [0002] Negative oxygen ions are known as "air vitamins", which can combine with positively charged particles such as dust, smoke, PM2. The substance reacts, breaking it down into carbon dioxide and water, thereby purifying the air. Small particle size negative oxygen ions can also pass through the blood-brain barrier of the human body, pass through the nervous system and respiratory system, exert its biological effects such as anti-oxidation, scavenge free radicals in the body, reduce blood viscosity, and enhance cardiopulmonary function and body immunity. [0003] Based on the function of negative oxygen ions to purify the air and promote physical health, coupled with the severe smog in recent years,...

AI Technical Summary

Problems solved by technology

[0004] (1) Most of the existing mature negative oxygen ion coatings are interior wall coatings, which have poor bonding force with metal substrates

[0005] (2) Most of the existing negative ion paint thinners are water, but due to the existence of organic resins, film-forming aids, etc., it cannot really achieve zero VOC

[0006] (3) The migration distance of negative ions is affected by air quality and wind speed, and the concentration added to the paint often makes the effect of removing formaldehyde insignificant
