A kind of interior wall latex paint containing selva powder and preparation method thereof

Abstract

The invention discloses interior wall emulsion paint with sesbania cannabina powder and a method for manufacturing the interior wall emulsion paint. The interior wall emulsion paint comprises, by weight, 5-7 parts of sesbania cannabina powder, 0.6-0.9 part of trimethylamine, 1-2 parts of bamboo charcoal powder, 0.2-0.4 part of photocatalysts, 12-18 parts of acetic styrene-acrylic emulsion, 0.2-0.6 part of hydroxyethyl cellulose thickeners, 0.1-0.3 part of wetting dispensing agents, 0.1-0.3 part of defoaming agents, 0.6-0.9 part of coalescing agents, 6-10 parts of titanium dioxide powder, 15-20 parts of triple superphosphate, 4-9 parts of calcined kaolin, 4-10 parts of talc powder, 0.15-0.35 part of preservatives and 0.15-0.35 part of antiseptics. The method includes sequentially manufacturing the sesbania cannabina powder and the trimethylamine; adding assistants into the sesbania cannabina powder and the trimethylamine, respectively mixing the assistants, the sesbania cannabina powder and the trimethylamine with one another and enabling the assistants, the sesbania cannabina powder and the trimethylamine to react with one another to obtain the final product. The interior wall emulsion paint and the method have the advantages that the interior wall emulsion paint with the sesbania cannabina powder is non-toxic and environmental friendly, and effects of adsorbing and dissipating volatile organic gas [VOC (volatile organic compounds)] generated by various indoor home ornaments can be realized.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an interior wall latex paint containing safflower powder. Background technique [0002] The pollution of interior decoration materials and furniture is the main cause of indoor air pollution; materials such as paint, plywood, shaving filler, interior wall paint, and plastic veneer all contain organic volatiles such as formaldehyde, benzene, ethanol, and chloroform. [0003] The main components of organic volatile gases (VOC) are: hydrocarbons, halogenated hydrocarbons, oxygen hydrocarbons and nitrogen hydrocarbons, including: benzene series, organic chlorides, Freon series, organic ketones, amines, alcohols, ethers, esters , acid and petroleum hydrocarbon compounds, etc.; when the VOC in the room reaches a certain concentration, it will cause symptoms such as headache, nausea, vomiting, fatigue, etc., and even cause convulsions and coma in severe cases, damage the liver, kidneys, br...

AI Technical Summary

Problems solved by technology

[0005] At present, the adsorption method is often used to remove formaldehyde and other harmful organic volatiles; the basic principle of the adsorption method is: add some natural or synthetic materials with more capillary pores and adsorption effect to the paint, and absorb formaldehyde in the capillary pores The disadvantage of this method is that it damages the physical properties of the paint; because in order to achieve sufficient adsorption, it is necessary to ensure that the capillary pores of the porous material are exposed to the surface of the paint film, so that the paint film cannot be too dense, so its scrub resistance is affected accordingly; adsorption Another disadvantage of the method is that when the formaldehyde content in the air is low, the adsorbed formaldehyde will be dissociated or replaced by other gases, which cannot achieve a good adsorption effect, and the adsorption capacity of the adsorbent material is very limited. It is easy to reach saturation; in addition, in the prior art, auxiliary materials such as bamboo carbon powder, photocatalyst, and vinegar-acrylic emulsion are also added as means for adsorbing formaldehyde and chemically reacting harmful elements in the coating body, although this scheme has certain effects, but There are still considerable harmful residues such as formaldehyde in the final latex paint, and the effect is not optimal; therefore, it is necessary to provide a formaldehyde-free, low content of other harmful organic volatiles, and can effectively remove formaldehyde, other harmful organic Volatile latex paint for interior walls has practical significance
