Abstract
The invention discloses a waterborne multifunctional composite coating, which has disinsection, sterilization and formaldehyde decomposing functions. The composite coating consists of the following components in percentage by weight: 10 percent of polyvinyl alcohol aqueous solution, 15 percent of waterborne epoxy resin, 20 percent of calcium carbonate, 15 percent of anatase nano-titanium oxide, 10 percent of sodium hexametahposphate, 10 percent of pyrethrum, 5 percent of veratrum, 2 percent of isothiazolizone and 13 percent of water, wherein the polyvinyl alcohol aqueous solution contains 20 percent of polyvinyl alcohol. The coating has complete functions, outstanding comprehensive performance and high adaptability, and contributes to improving the environmental quality.
Description
Technical field
The present invention relates to a kind of multi-functional composite coating, the water-soluble multifunctional composite coating of particularly a kind of desinsection, sterilization and decomposing formaldehyde.
Background technology
Mosquitos and flies is human public hazards, interference people's life, existing people generally use spray-type sterilant and heating evaporation type sterilant; It has convenience, desinsection advantage rapidly, but its toxicity is big, and peculiar smell is arranged; Environment is had pollution, and the anti-area that kills is little, timeliness short, and the toxic residue amount is big; And a kind of sterilant of life-time service is prone to develop immunity to drugs, and needs constantly more new variety; This disinsection method needs people often to carry out desinsection work, almost must carry out every day.Along with the development people of technology have invented sterilant is made an addition in the coating, process insecticidal coating, apply body of wall, thereby when insect rests on the body of wall, touch the sterilant death of tagging leaving sterilant on the body of wall with this coating.And mosquitos and flies can land, so this method obtained good effect, and the user also needn't carry out killing mosquito everyday, and insecticidal coating can be permanently effective, but this method has also been brought toxicity, to the also toxic effect of people on body of wall when killing mosquitos and flies.The objective of the invention is to provide a kind of improved coating, this coating not only has good decoration effect and insecticidal effect simultaneously and people and animals is not constituted harm, but also will guarantee that price is cheap extensive with use range.
Coating is contaminated owing to raw material in process of production, equipment reasons such as clean or water source be not unholiness all possibly cause bacterium being incorporated in the coating material production prescription in any stage of manufacturing processed; Coating is in case pollute upward bacterium; The mikrobe that adheres to production at coatingsurface can bring a series of troubles such as a series of loss of gloss, distortion to coating; Even can make coating produce cracking, inharmonious, even more serious also can cause paint coatings corrosion spalling etc.Therefore exploitation has the trend that the coating of fungi-proofing effect is coating development industry.
Along with growth in the living standard, and the continuous reinforcement of health perception and environmental consciousness, people are to own indoor environment growing interest.People use the various type materials such as wood-based plate to carry out interior decoration mostly; But wood-based panel products such as the wood veneer that is pressed into by urea-formaldehyde resin adhesive, Phenol aldehyde resin, melamine-formaldehyde resin adhesive etc., shaving board, density board, fine workmanship's plate become the main source of indoor formaldehyde again when beautifying the room.Producing and use the free formaldehyde that discharges in the wood-based plate, pollute living environment, infringement people's health.The reason of wood-based plate release formaldehyde is roughly following: remaining unreacted free formaldehyde when (1) resin is synthetic; When (2) resin is synthetic, participated in reacting the formaldehyde that generates unstable group, in hot pressing, can discharge again; (3) when resin is synthetic, be adsorbed on colloidal particle protonated formaldehyde molecule on every side, under electrolytical effect, also can discharge.
Formaldehyde can change methyl alcohol in human body, thus can cause more weak anesthetic action, influential to optic nerve.Formaldehyde can cause cns, the active change of body endoenzyme and internal secretion, immune change; The formaldehyde of high density is all toxic for neural system, immunity system, liver, and exciting eye conjunctiva, respiratory mucosa and producing shed tears, runny nose, the conjunctivitis that causes, pharyngolaryngitis, asthma, bronchitis and allergic disorder.As suspect carcinogen, multiple animal shows that formaldehyde has clear and definite carinogenicity with formaldehyde for American National Occupational safety in 1981 and health institute.Formaldehyde is long latent period, and the artificial board release period is 3~5 years, and by formaldehyde-caused occupational asthma, be several weeks to the several years its latent period.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of above-mentioned coating, make this coating can satisfy above-mentioned requirements, this coating is made up of following components in weight percentage:
Polyvinyl alcohol water solution 10%,
Aqueous epoxy resins 15%,
Lime carbonate 20%,
Dichloride in anatase type titanium oxide 15%,
Sodium hexametaphosphate 99 10%,
Pyrethrum 10%,
Black false hellebore 5%,
Isothiazoline 2%,
Water 13%;
The weight content of Z 150PH is 20% in the said polyvinyl alcohol water solution.
Coating of the present invention all has good killing effect and has very long residual effect mosquito, fly and cockroach etc. through units concerned's probationary certificate, its desinsection speed even surpass the desinsection paint of France, the catalytically decomposed of nano titanium oxide PARA FORMALDEHYDE PRILLS(91,95) simultaneously; And the sterilization of sterilant isothiazoline reached the effect of integrated control, and three kinds of function match, synergy are obviously; Can desinsection; More can sterilization, and remove formaldehyde, be a kind of coating of very environmental protection.
In addition, detect proof to the person poultry harmless, also do not constitute other untoward reaction through health and epidemic prevention department.This coating low cost of manufacture, price is cheap, the use in enormous quantities that is very suitable for urban and rural housing, hospital's schoolhouse, army's barracks, stock-farms and the multiple scopes such as mill store of hygienic requirements are arranged.
It is easy, easy to operate that the method for manufacturing coating of the present invention is implemented, and it can make the product that produces satisfy These characteristics.
Embodiment
To combine embodiment to come coating of the present invention and method of manufacture thereof are done more detailed description below.
Embodiment 1:
1) earlier 10% polyvinyl alcohol water solution and 15% aqueous epoxy resins are put into container and carry out even mechanical stirring; Stirring velocity is 300r/min, adds lime carbonate 20% then, Sodium hexametaphosphate 99 10%; And be equipped with the ultrasonic stirring of auxiliary machinery down 15min; Ultrasonic frequency is 500Hz, and power is 280W, and stirring velocity is 280r/min;
2) add pyrethrum 10%, black false hellebore 5%, isothiazoline 2% continues to stir 5min, and rotating speed is 100r/min;
3) add dichloride in anatase type titanium oxide 15% again, ultrasonic echography 10min, power are 500W, and frequency is 500Hz;
4) add entry 13%, promptly make multi-functional composite coating.
Table 1 performance comparison
Bactericidal property | Insecticidal properties | The decomposing formaldehyde ability | |
Embodiment 1 | 93% | 95% | 88% |
