Interior wall latex paint containing sticky rice glue and preparation method of interior wall latex paint

Abstract

The invention discloses an interior wall latex paint containing sticky rice glue and a preparation method of the interior wall latex paint. The interior wall latex paint is prepared from the following raw material components in parts by weight: 3-6 parts of sticky rice glue, 0.8-1.2 parts of robinia pseudoacacia powder, 1-2 parts of bamboo coal powder, 0.2-0.4 part of a photo-catalyst, 12-18 parts of a vinyl acetate-acrylic emulsion, 0.2-0.6 part of a hydroxyethyl cellulose thickening agent, 0.1-0.3 part of a wetting dispersant, 0.1-0.3 part of a defoaming agent, 0.6-0.9 part of a coalescing agent, 6-10 parts of titanium dioxide, 15-20 parts of triple superphosphate, 4-9 parts of calcined kaolin, 4-10 parts of talcum powder, 0.15-0.35 part of an anticorrosive agent and 0.15-0.35 part of a mildew preventive. The preparation method comprises the following steps: firstly preparing sticky rice glue and the robinia pseudoacacia powder sequentially, and then adding additives, and respectively mixing to have a reaction to prepare a final product. The interior wall latex paint containing the sticky rice glue, disclosed by the invention, is non-toxic and environment-friendly and also has adsorption and decomposition effects on organic volatile gas (VOC) generated by various indoor home decorations.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an interior wall latex paint containing glutinous rice glue. 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...

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
