Problems solved by technology

[0003] To sum up: the existing wall paint only removes formaldehyde through physical adsorption, and cannot achieve the real effect of removing formaldehyde. The absorbed formaldehyde has the disadvantage of secondary release, and the construction smell is heavy, producing annoying smell, which affects the health of construction workers

Abstract

The invention provides a wall paint which comprises water, titanium pigment, a natural inorganic material which can adsorb oxymethylene, a combining sodium silicoaluminate and a polymer emulsion of functionality group with a molecular structure which is H2N-CO-NH2. The wall paint provided by the invention comprises the following steps of: firstly carrying out rapid physical adsorption on the oxymethylene through the natural inorganic material and the combining sodium silicoaluminate, then, utilizing the functionality group with the molecular structure which is H2N-CO-NH2 and the oxymethylene to generate a chemical reaction to degrade the oxymethylene, generating an innocuous substance and water, achieving the effect of fully eliminating aldehyde and protection decoration. In addition, polarity which is negative ion nature mineral and an accessory ingredient is also utilized, hydroxy negative ion can realize permanence release, the action of high efficiency antibiosis and eliminating peculiar smell is achieved, and finally, the novel wall paint is formed and has the advantages of fully eliminating aldehyde, protecting wall face, and has a good decorative effect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wall paint. Background technique [0002] At present: the wall paints sold on the market are all based on adding fillers with a network structure such as sodium aluminosilicate to achieve the effect of removing formaldehyde. This method is to physically adsorb formaldehyde through fillers with a network structure such as sodium aluminosilicate. The disadvantage of secondary release also affects other properties of the paint film, such as the paint film is not easy to clean. Therefore, ordinary wall paints cannot achieve the effect of removing aldehydes; and the formaldehyde-free wall paints sold on the market are only replaced with additives, and cannot achieve the effect of removing aldehydes, and the construction smell is heavy and produces annoying odor, affecting the health of construction workers. [0003] To sum up: the existing wall paint only removes formaldehyde thr...
