Description
Technical field
The invention belongs to and building material technical field, particularly relate to a kind of preparation method of interior operating room wall putty powder.
Background technology
Kind and the output of current China putty product are all many, but there is brand, have the putty product of standard less, major part prepares at building-site, materials are careless, formula arbitrarily, as long as levelling body of wall, the performance few people such as cohesive strength, water tolerance, alkali resistance, freeze-thaw resistance and construction are concerned about.A good building coating kind, based on the putty layer matched with it that must have, its decorative effect of guarantee.Domestic use comparatively widely building putties is Mierocrystalline cellulose great Bai putty and gesso.There is the shortcomings such as cohesive strength is low, poor water resistance in tradition putty, its quality is wayward.Operation theatre is the place for patient provides operation and rescues, and is the important technology department of hospital.Operation theatre metope and top ceiling adopt can sound insulation, solid, smooth, tight, fire prevention, material damp proof, easy to clean, ensure the gnotobasis of Operation theatre.Therefore, high, the water-tolerant of cohesive strength, smooth, firm solid, fungi-proofing, interior operating room wall putty powder that workability is excellent is urgently developed, to meet the decoration requirements of hospital.
Chinese patent CN200810187826.8 discloses a kind of single component water-based natural antibacterial inner and production method thereof.Its composition and weight part thereof are: water 334.5, frostproofer 15, neutralizing agent 1.5, wetting agent 2, dispersion agent 6, defoamer 2, pigment 200, natural mineral anti-biotic material 25, natural phant anti-biotic material 100, anticorrosion and bactericidal agent 2, emulsion 300, defoamer 2, thickening material 10.But the phenomenon faded easily appears in putty powder prepared by the method, and slickness is inadequate, can not UV resistant, ozone sterilization repeatedly, the putty powder being not suitable as interior operating room wall uses.
Chinese patent CN201410491176.1 discloses a kind of ceramic simulating coating and preparation method thereof, and ceramic simulating coating comprises the following raw material according to mass fraction meter: polyvinyl alcohol 30-40 part, talcum powder 25-28 part, light calcium carbonate 20-22 part, tributyl phosphate 0.5-1 part, trimeric cyanamide 5-10 part, boric acid 2-5 part.But this coating can not play anti-microbial effect, also easily produces obnoxious flavour, the putty powder be difficult to as interior operating room wall uses.
Therefore be badly in need of that a kind of anti-microbial property is good, water-tolerant, pollution-free, cohesive strength large, long service life, radiation hardness, erosion-resistant smooth putty powder preparation method, to meet the needs of interior operating room wall finishing.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of preparation method of interior operating room wall putty powder is provided.
