Abstract
The invention relates to antibacterial paint harmless to human body health. The paint is composed of the following compositions in parts by weight: 18-29% of titanium dioxide, 15-30% of acrylic acid copolymerization emulsion, 5-10% of polyethylene wax emulsion, 3-5% of butyldiglycol, 1-3% of a thickening agent, 2-5% of a dispersant, 0.5-3% of an antifoaming agent, 16-28% of deionized water, 3.5-8% of propylene glycol, 2-3% of a coalescing solvent and 10-20% of a chitosan-inorganic metal ion complex. The antibacterial paint is prepared by employing a routine paint preparation method. The paint is simple in preparation technology and convenient to use, and has good inhibiting and killing effect on multiple bacteria and fungi.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of harmless antibacterial bacteriostatic coating.
Background technology
Along with people's standard of living constantly improves, people are also more and more higher to the requirement of living-hygienic quality, and how effectively antibacterial, degerming is the challenge that people propose the modern life.Antibiotic paint industry is still in developmental stage at present, solves the application art of anti-biotic material in coating, is pendulum common problem in face of coating industry.The coating with anti-microbial effect is called antibiotic paint, is generally in coating, to add sterilant.
Modal commercial sterilization agent is based on following several activeconstituentss: ZPT (ZPT), 3-iodo propinyl-n-normal-butyl carbamate (IPBC), 2-n-n-octyl-4-isothiazoline-3-ketone (OIT), 4, the chloro-2-of 5-bis-(n-octyl group)-4-isothiazoline-3-ketone (DCOIT), derosal (CBZ) and m-tetrachlorophthalodinitrile (CTL).Above-mentioned sterilant is knownly can effectively stop fungi and part algal grown mostly, but its effect for bacterium is completely unclear.And because it is chemosynthesis composition, human body is had to injury in various degree, particularly derosal and m-tetrachlorophthalodinitrile, European sterilant instruction (BPD) more has strict restrictive clause to it.Derosal is strictly reclassified as: in the time containing this active ingredient that exceedes 1000ppm in paint, must indicate " toxicant R46 " (may cause the infringement of heredity gene), and corresponding posting " raw and bloody bones " symbol, emphasize " being only limited to professional person uses ".In the chemical producting safety specification sheets of paint, must show " causing transgenation classification 2 ".M-tetrachlorophthalodinitrile will have R40 label (minority evidence shows carcinogenic consequence).
Money base sterilant is the antibacterial and protective method that another kind is widely known by the people, and in the technical literature of many medical facilities and other polymkeric substance, all has and relates to.But its using method in paint is not still by people is known.Because it has anti-microbial activity, therefore money base sterilant uses as benchmark under study for action.At the isothiazoline base sterilant of U.S.'s new registration, n-butyl-1,2-benzisothiazole-3-ketone is also in research range.
And along with the development of biotechnology, increasing natural radioactivity antimicrobial substance is found, this also provides new thinking for people seek a kind of non-harmful natural antibacterial coating.Chitosan claims again chitin, chitin, chitin.In weak acid solvent, be easy to dissolve, it is worthy of note especially dissolve after solution in contain amino (NH
2 +), these amino are by carrying out anti-bacteria in conjunction with negatron.The Antibacterial activity of chitosan, makes it have a wide range of applications in fields such as medicine, weaving and food.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of coating that contains natural radioactivity antimicrobial factors, harmless, manufactures simple, easy to use.
Antibiotic paint of the present invention is grouped into by the one-tenth of following weight part:
Titanium dioxide 18～29%, acrylate copolymer emulsion 15～30%, polythene wax emulsion 5～10%, butyl carbitol 3～5%, thickening material 1～3%, dispersion agent 2～5%, defoamer 0.5～3%, deionized water 16～28%, propylene glycol 3.5～8%, agglomerated solvent 2～3%, chitosan-inorganic metal ion title complex 10～20%.
Described film coalescence aid is selected from a kind of in ethylene glycol phenyl ether, phenylcarbinol, propylene glycol phenylate or their mixture.
Described thickening material is selected from a kind of in polyacrylic acid, BK-887A, WT-105A or their mixture.
Described dispersion agent is selected from a kind of in lithium magnesium silicate, OP-5035, OP-8146 or their mixture.
Described defoamer is selected from a kind of in SP-202, XP-1273, F-111, NXZ or their mixture.
The preparation method of antibiotic paint of the present invention is general preparation method in the industry.
The invention has the beneficial effects as follows: adopt crude substance chitosan as antiseptic-germicide, the amount of the harmful chemical in coating is dropped to minimum, can not be detrimental to health.Meanwhile, this coating can kill airborne mould and other bacteriums effectively.This fungicidal paint is easy to use, both can brush with common brush, also can be sprayed on building or decoration surface.
