Description
Technical field
The invention belongs to indoor decorating wallcovering field, be specifically related to a kind of antibiotic emulsion paint.
Background technology
Emulsion paint has easy construction, the feature that color is various, dominate in inner wall decoration at home, but conventional latex paint does not have anti-microbial effect, in hospital, children or room, classroom easily because bacterial adsorption is on body of wall, people just becomes easily infected by bacterium with body of wall contact because of carelessness, thus produces harm to health.At present, common antibiotic emulsion paint on the market generally adopts the mixture of organic antibacterial agent CMIT/MIT/ organic bromine, or inorganic silver ion antimicrobial agent, the mixture of organic antibacterial agent CMIT/MIT/ organic bromine is responsive to PH, addition is large, and toxicity is relatively greatly, irritant to people and animals.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide a kind of for indoor wall decoration, has the emulsion paint of good antibacterial effect.
The technical solution used in the present invention: a kind of antibiotic emulsion paint, is characterized in that being made up of the raw material of following masses part: water soluble acrylic acid 150 ~ 350 parts, defoamer 1 ~ 5 part, sanitas 2 ~ 4 parts, dispersion agent 5 ~ 10 parts, pigment 150 ~ 300, filler 150 ~ 350 parts, thickening material 2 ~ 9 parts, flow agent 1 ~ 10 part, nano inorganic negative ion antibiotic agent 6 ~ 15 parts, nanometer polymer tiny balloon 50 ~ 90 parts, bamboo vinegar liquid 50 ~ 90 parts, solubility promoter 1 ~ 5 part, pamorusa oil 10 ~ 20 parts, water 100-350 part.
Described defoamer comprises silicone antifoam agent, polyether antifoam agent.
Described sanitas is selected from one or more in 1,2-benzisothiazole-3-ketone, methylisothiazolinone, CMIT.
Described dispersion agent is selected from sodium polyacrylate salt, modified polypropene acid solution class or modified polycarboxylic acid salt.
Described pigment comprises rutile TiO_2, modified phosphate.
Described filler be selected from calcined kaolin, water-ground limestone, diatomite, talcum powder, wollastonite or process white more than one.
Described thickening material is nano fumed silica or Natvosol.
Described flow agent is selected from cross-linking organosilicon polyoxyalkylene acrylate lipin polymer, dimethyl polysiloxane emulsion or polysiloxane-polyether copolymer.
