Description

The processing technology of one species granite water paint
Technical field
The present invention relates to the processing technologys of building material technical field more particularly to a species granite water paint.
Background technology
Granite is a kind of natural stone material, is widely used in the outdoor facing of building.But granite cost is sufficiently expensive, and Make facing with public danger in external wall, the veneer for being not easy large area or external wall of high-rise building uses.Therefore, in order to build The luxurious effect of granitic appearance can be reached by building object, copied granitic material and constantly gushed out, due to granitic color polyisocyanate Property so that its imitating technology is sufficiently complex, and people need a kind of material for manufacturing simplicity to simplify the complexity of its imitating technology, In this context, class granite coating comes into being.In China, the research of class granite coating starts from the eighties in last century, when When class granite coating based on oil-in-water type (O/W) class, bin stability is best, and most widely used, but contains in its coating There are a large amount of volatile organic compounds (VOC), the health and ambient enviroment of construction personnel are harmful to, unfavorable environmental protection.In productivity Today of high development, people propose increasingly higher demands to the health of itself and the living environment of surrounding, " energy saving " and " environmental protection " has become our state basic policy.Water-in-water type (W/W) class granite coating (hereinafter referred to as aqueous class granite coating) is just It is the hot spot for having become major water paint manufacturing enterprise research in such a situa-tion.Aqueous class granite coating is at first U.S. Compatriots are studied, and the 1990s, mid-term, just became the coating products that can be applied on building, aqueous class granite coating Appearance be a quantum jump in traditional architecture paint field, it overcomes the O/W oil-in-water type classes that 20th century, 80 mid-term occurs Granite coating contains the shortcomings that poisonous and harmful substances such as volatile organic compounds, more energy-saving and environmental protection.It is that new generation of green is built Build coating.Have a vast market prospect.Recent years, the manufacturing enterprise of the aqueous class granite coating of studies in China is more, but Most of aqueous class granite coating quality ginsengs time are uneven on the market, and some color tablets are unstable, broken;Some color tablets borders are not Clearly, but all there is defect such as storage period is short, easy bleeding, muddy water, drastically influence the popularization of aqueous class granite coating and make With.
Diatomite is that a kind of have that natural nano microcellular structure, large specific surface area, heap density is small, main component is unformed The natural siliceous porous nonmetallic mineral of SiO2, be widely used in the filtering of beer, beverage, drinking water, commercial grease etc. with And the fields such as sewage disposal, building materials, chemical industry, agricultural, rubber and plastic filler, papermaking filler, it is that many industries are essential Functional mineral material, has broad application prospects, and with the raising year by year of people's level of consumption, environmental protection finishing concept is already It is rooted in the hearts of the people, and diatomite is added in into finishing field, especially coating, be the class that recent years, technical staff seek assiduously Topic.
China is diatomite reserves big country, is only second to the U.S. in the world, occupies second.But the diatomite reserves in China In, the overwhelming majority is Low grade resource, and the direct applied high-quality diatomite resource of energy is less.In exploitation level-one diatomite resource In the process, more than 75% low-grade diatomite resource is discarded, not only the diatomite resource of serious waste preciousness, but also is polluted Local environment.The comprehensive utilization of low-grade diatomite ore is current and following diatomite utilization industry with deep process technology It is badly in need of.In low-grade diatomite physical upgrading, scouring is very important link.The effect of scouring mainly makes ore Mill stripping is generated between grain and particle, achievees the purpose that cleaning, polishing and size degradation.
Since diatomite is usually to be formed by the remains deposition of unicellular water plant diatom, the uniqueness of this diatom Its anatomy can be formed in the free silica in it can absorb water, deposit after its end of life, formed under certain geological conditions Diatomite Deposit in existing diatomaceous production, uses after fine powder is crushed to after generally being dried after scouring, just because of The long-term deposition of Diatomite Deposit, although internal distribution micropore, micro-pore shape and not of uniform size under microscope is applied particularly to During class granite coating, noise reduction, absorption, adjusting air humidity, remove formaldehyde effect and have with the conjugation of pigment It waits to improve.
Through retrieval, Chinese patent application, application number:201210182067.2 publication date:2016.1.20, one kind is disclosed Water paint, water paint fraction by weight include following component:White cement 70-150;Rutile type titanium white 5-15; Urushiol-based emulsifier 30-70;Urushiol-formaldehyde polymer emulsion 70-110.Water paint of the present invention is added with raw lacquer, Hard, bright, wear-resisting, heat-resisting, the corrosion resistant advantage of film of raw lacquer has been given full play to, and has coordinated and adds urushiol-based emulsifier Emulsify raw lacquer, it is ensured that it is good in the compatibility of raw lacquer, fine and close, rigid interfacial film is advantageously formed, and laccol base emulsifies Agent can participate in the film formation reaction of raw lacquer, avoid harmful effect of traditional emulsifier to film performance, have extremely strong hard Degree.But when the invention is applied to interior decoration, after roller coating smoothes out, adsorption capacity is not good enough.
The content of the invention
