Water-based fluff paint containing negative oxygen ions and preparation method thereof

Abstract

The invention relates to the technical field of paint, and particularly discloses a water-based fluff paint containing negative oxygen ions. The water-based fluff paint containing negative oxygen ionsis composed of an elastic emulsion, a primer, a wetting agent, a defoaming agent, a film-forming assistant, a thickening agent, negative oxygen ions, fluff powder and deionized water. The negative oxygen ion water based fluff paint prepared according to the invention has the properties of removing methanol, insulating heat, resisting flame, proofing water and containing negative oxygen ions, andis high in reusability, green and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water velvet paint containing negative oxygen ions and a preparation method thereof. Background technique [0002] Paint, the so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding pigments and fillers , add corresponding additives, and prepare viscous liquid with organic solvent or water. [0003] Decorative coatings are used to decorate and protect the exterior walls of buildings, so as to make the buildings look beautiful and tidy, so as to achieve the purpose of beautifying the urban environment and giving people a refreshing space. At the same time, it can also protect the building wall and prolong its service life. Wall decoration coatings can be roughly divided into exterior wall coatings and inter...

Problems solved by technology

[0004] However, in the prior art, because conventional decorative coatings only have basic waterproof and moisture-proof functions, and because the primer and the topcoat are not matched, the coating film is affected by external influences (mechanical action, temperature change, etc.) and shrinkage stress is generated, causing the paint The film is cracked or cracked; the top coat (spray, brush, roller) is applied before the primer is completely dry, or the first coat is too thick, and the second coat is applied before it is completely dry, so that the two coats of paint stretch inside and outside Inconsistency; indoor paint is used for outdoor or metal surface primer is used for wood; wooden substrates contain turpentine that has not been removed and treated, and the paint film will ooze out over time, causing local cracks; the moisture content of wood is too high, and it will occur over time Deformation causes cracking; too much curing agent is added, or the wrong curing agent is used; the construction is too thick; the construction environment is harsh, the temperature difference is large, the humidity is high, and the paint film is stretched and contracted by cold and heat, causing cracking

Inadequate base and top coats result in poor adhesion between layers; the surface is unclean, stained with oil, water or other dirt; improper surface treatment, such as putting putty or painting on the wood surface without sanding , so that the oil of the topcoat is absorbed by it and causes it to fall off. The wood surface is not effectively sealed; The paint is too hard or the primer is very smooth, and the topcoat is applied directly without sanding; it will cause pathological phenomena such as paint film peeling, peeling, drumming, and peeling

[0005] Secondly, the practical time of decorative paint is short. The overall protection time of the coating of exterior wall paint is only 1-2 years in the case of sun-exposed rainforest, and the overall protection time of the coating of interior wall paint is also short. In a maximum of 3-4 years, the old paint film layer needs to be removed again, and then the second spraying is carried out to resume work. Not only the amount of work is large, but also when the paint film layer is removed, a large amount of paint film layer powder is flying and solid residue, causing secondary pollution
