Abstract
The invention relates to a sandstone-like indoor building coating, and providing an indoor building coating which aims at solving the problems that an existing building coating is poor in thermal insulation, sound insulation and antibiosis and detoxication property, and is improved by using a photocatalyst. A titanium dioxide doped nano powder photocatalyst for decomposing pathogenic bacteria and harmful gases in a photocatalysis manner is added into the building coating, air micro capsules for improving the thermal insulation property of the coating are further added, the viscosity and the internal stress of the coating are reduced, the hollow glass microspheres with leveling property are added, and the rigid polyurethane foam powder which is good in thermal insulation, light in weight, large in specific strength and convenient to construct is added. The sandstone-like indoor building coating has the advantages that the packaging, the transportation, the storage and the use of the product are all convenient and simple when compared with those of a paste product, the production cost is low, and the property is excellent.
Description
Technical field
The present invention relates to a kind of building coating, particularly relate to a kind ofly improve that building coating is heat insulation, the sandstone shape indoor architectural paints of sound-proofing properties and antibacterial and detoxicating performance.
Background technology
Traditional inner wall of building latex coating needs because of it organic solvent such as frostproofer and film coalescence aid adding more amount in coating, cause the content of volatile organic compound of coating higher, in addition in order to when preventing coating to store become morally degenerate and film mouldy, the harmful organic antimildew disinfectant adding more amount is also needed in coating, this not only directly has influence on the physical and mental health of occupant, and have ageing, through after a period of time, just lose mildew-resistant effect.In indoor decoration, due to the organic volatile larger to human toxicity such as a large amount of formaldehyde, benzene class can be discharged in the timber such as wood furniture, three-ply-wood and solvent-borne type wood lacquer, people after fitting up complete two to April, just must can move in the new home after strong smell is thin out.Even if like this, the indoor organic volatile that still extended residual is harmful.For solving the problem, in recent years, both at home and abroad all in the research improving improvement latex coating correlated performance by nano material of throwing oneself into, as JPI00254352 describes a kind of weathering resistance antibiont coating, crystal fine particle is burnt till by the oxide compound section of parcel containing Ag, Cu or Zn on lime glue, be added to again in ACRYLIC EMULSION, form weathering resistance antimicrobial coating.CN1277234A by adding nano material in formula, makes the performances such as ageing-resistant, ultraviolet radiation preventing, the antiseep of coating significantly improve, thus improves the cost performance of coating.But the coating involved by above-mentioned patent, its content of volatile organic compound is higher, and the film that these coating are formed all can not decompose toxic odor.
Summary of the invention
The object of the invention is to solve that existing building coating is heat insulation, sound-proofing properties, antibacterial and detoxicating poor performance, a kind of sandstone shape indoor architectural paints adopting photocatalyst material modification is provided.
To achieve these goals, the present invention is by the following technical solutions:
A kind of sandstone shape indoor architectural paints, its component by weight, comprising:
Silicate white cement 30 ~ 50, doping titanium dioxide nano powder 1 ~ 10, hollow glass micro-ball 5 ~ 15,
Air microcapsules 5 ~ 15, hard polyurethane foam powder 20 ~ 30, dye 0 ~ 0.5.
This coating shape is powdery, and separately packs by component, each component is mixed by weight ratio at the construction field (site), and the degree of mixing well suitable spray-coating that adds water can use.
In the technical program, silicate white cement is normal silicate white cement.Can purchase in addition at the construction field (site), reach and reduce coating traffic capacity and use cost.
Doping titanium dioxide nano powder has excellent photocatalysis performance and chemical property.Its stable chemical nature, nontoxic, be desirable photocatalyst material, be widely used in the fields such as purifying air, antibacterial, sewage disposal.But for simple nanometer titanic oxide material, its performance still can not meet actual needs, because its greater band gap, can only absorb the UV-light accounting for sunlight about 5%, can not effectively utilize visible ray, make to receive constraint greatly and restriction in the middle of the application of reality.For this reason, in order to widen the scope of nano titanium oxide spectral response, modification is carried out to photocatalysis material of titanium dioxide, the nanometer titanium dioxide photocatalysis material of modification is added in existing building coating, the microbial virus be attached on coating, bacterium can be decomposed, and harmful indoor organic volatile matter.
Air microcapsules is a kind of fine and smooth powdery white microcapsule, is to adopt chitosan, yeast extract and sodium alginate to produce by crosslinking reaction the powdered granule that complex coacervation forms the heat insulation good air of encapsulation or carbon dioxide.Adding air microcapsules makes coating have heat-insulation and heat-preservation, energy-conservation and the effect of insulating noise, reaches indoor cool in summer and warm in winter, the target that room is more comfortable.
Hollow glass micro-ball is a kind of lightweight non-metallic multifunctional material, its diameter is between 15-135 μm, outward appearance is pure white, good fluidity, becomes circle rate more than 97%, its hardness is high, quality is light, water-fast, corrosion-resistant, nontoxic, radioprotective, fire prevention, sound insulation, insulation.It adds correctability building coating, has the advantageous characteristic that wear resistance is strong, ultimate compression strength is high, thermal conductivity is low.It also reduces viscosity and the inherent strain of coating, thus bring benefit to coating property, increase levelling property; Stop " fish tail " and " tangerine peel " phenomenon that application produces.
Hard polyurethane foam powder adopts excellent polyethers to be major ingredient, adds other auxiliary material, small powder combinations produce forms.Hard polyurethane foam mostly is unicellular structure, has that insulation effect is good, lightweight, a good characteristic such as specific tenacity is large, easy construction, also has the features such as sound insulation, shockproof, electrical isolation, heat-resisting, cold-resistant, solvent resistant simultaneously.Hard polyurethane foam, as material of construction, in European and American developed countries, about usage quantity accounts for the half of total flow of hard bubbling, at home, hard bubbles also general unlike western developed country in the application of construction industry, so the potentiality of development are very large.
Dye, for meeting the collocation of colour requirement needed for architectural design, also can.
The invention has the beneficial effects as follows: packaging, transport, the storage of product and use is all convenient and simple than creamy product, low cost product, excellent property; In indoor architectural paints, add photocatalyst material improve the performance that building coating decomposes harmful microorganism and obnoxious flavour, add air microcapsules, heat insulation, sound-proofing properties that hard polyurethane foam powder improves coating; Add the spraying application performance that hollow glass micro-ball improves coating.
