Abstract
The invention discloses a medical waterproof bactericidal paint and a preparation method thereof. The medical waterproof bactericidal paint is prepared from water, calcium carbonate, styrene, acrylic acid, acetic acid, dimethylbenzyldodecyl ammonium bromide, silicon dioxide, magnesium oxide, methyltrimethoxy silane, isopropanol and acetic acid. After the medical waterproof bactericidal paint is applied to a nonwoven fabric or aluminum sheet, the surface drying time is 45-65 minutes, the solid drying time is 95-115 minutes, and the scrub resistance is 2000-4000 times. The product is nontoxic, does not have abnormity after the alkali resistance test for 3-5 days, and does not blister or shed after the water resistance test for 15-35 days. The medical waterproof bactericidal paint is bactericidal and antitoxic, has the advantages of vapor permeability, bactericidal property, simple preparation method and simple and accessible raw materials, and is a thixotropic paint.
Description
Technical field
The present invention relates to medical material tech field, particularly relate to a kind of medical waterproof fungicidal paint and preparation method thereof.
Background technology
HHT higher high tensile antibiotic paint develops a kind of HHT higher high tensile antibiotic paint for fields such as building, decorations by liquid plastics company of Britain, and this coating can kill mould in air and other bacteriums effectively.It is reported, the sterilant containing stronger germicidal action in this fungicidal paint, this sterilant can realize organically combining with various composition in coating, therefore can permanently effective sterilization.This coating can not be detrimental to health, and this fungicidal paint is easy to use simultaneously, both can brush with common brush, also can be sprayed on building or decoration surface.After brushing or spraying, body surface can form the Elastic Film of at least thick than common coating 5 times, durable, water-fast, chemicals-resistant corrosion.
Nearly all inanimate surfaces has microorganism.Also each quasi-microorganism is had in other place, as: MCO; The public place of high-risk infection: station, hotel, hotel, airport; Bathroom under wet environment, spa is cooling tower in one's power.In above-mentioned sensitizing range, so-called multi-drug resistant bacteria and pathogenic bacteria, fungi has rising tendency.Have the surface, place of bacterial growth to threaten human health, it also have impact on the actual use value of body surface or causes surface denaturation simultaneously.
Reduce cross infection probability: exceed much than general private place with germ density public place on body of wall in air, if can not get effective control, cause cross infection easily.Use antibiotic paint, can effectively purify air in institute, greatly reduce cross infection probability.
The control effect of the progressive transmissible disease occurred frequently to burst: the control device of domestic public place in purifying air still seems not enough, the case once rise, just have in larger institute and propagate risk, if use antibiotic paint, for other risk prevention instruments, a comparatively ideal solution of can yet be regarded as.
Eliminate metope mildew: mould is the one of bacterium, and common environmental protection coating material cannot be killed, therefore the mould long-standing exercise question becoming a lot of public place of puzzlement of body of wall, brushing repeatedly that can only be passive.And the mildew-resistant grade of antibiotic paint reaches 0 grade of not mildew, use the antibiotic paint of mildew-resistant 0 grade that body of wall not only can be kept attractive in appearance, also can save the manpower, material resources and financial resources that specialized hospital safeguards.
Put things right once and for all: the coating products reaching national industry yardstick, its sterilization function can keep not random sterilization, bacteriostasis in for a long time.Increasing public organizations and the Designers specializing in specialized hospital's design at present, so design institute has progressively appreciated this point, is designed to antibiotic paint to new project at the beginning of design by interior wall coating.
