The viscosity of the silica sol interior wall coating is 80-90 Pa.s, the fineness of the silica sol interior wall coating is 80-90 microns, the stability of the silica sol interior wall coating is 8-12 months, and the phenomena of frothing, shedding and wrinkling after the coating is soaked in water for 24 hours are avoided; the film coating has a smooth appearance and is uniform in color; the coating can resist xerotripsis for 400-500 times, is good in heat resistance and short in drying time, can be produced extensively and can replace an existing material continuously.
Description
Technical field
The application belongs to paint field, relates in particular to a kind of silicon sol interior wall coating.
Background technology
Coating is construction most convenient, and price is cheaper, and the good results are evident, a kind of Chemicals that value-added rates is high.Be applied to building, boats and ships, vehicle, bridge, machinery, chemical industry equipment, electronic apparatus, ordnance, canned food, the every field such as school supply and stationery.China's coating circle more authoritative < < coating process > > mono-book is definition like this: " coating is a kind of material; this material can be coated in article surface by different construction technologies, forms and adheres to firmly, has some strength, continuous solid film.The film common name forming is like this filmed, and claims again paint film or coating." paint finishing can and form the material of complete and tough and tensile protective membrane with the fine bonding of body material in body surface, is called coating.Coating and paint are identical concepts.Paint is people's custom titles used for a long time, introduces after China, just utilizes in building trade always.The effect of coating may be summarized to be three aspects: provide protection, decoration function, specific function effect.The general composition of coating: comprise filmogen, color stuffing, solvent, auxiliary agent.
China's paint industry grows stronger day by day under the promotion of downstream industry, and as the building coating of one of them branch, has also obtained significant progress.Statistic data demonstration, within 2011, Chinese architecture coating amounts to approximately 351.82 ten thousand tons of output, increases by a year-on-year basis more than 30%.As can be seen here, although Chinese architecture paint industry has experienced the impact of global financial crisis in 2008, the pressure that the prices of raw and semifnished materials go up and Central Bank increases the interest and brings, its growth momentum does not still subtract, and is also keeping higher rate of increase.
Interior wall coating is exactly the emulsion paint of generally fitting up use.Emulsion paint is emulsion coating, according to the difference of base material, is divided into polyvinyl acetate emulsion and the large class of ACRYLIC EMULSION two.In the making composition of interior wall coating, substantially water, pigment, emulsion, weighting agent and various auxiliary agent, consist of, these starting material are not contain what toxicity.As emulsion paint, may be toxic be mainly that ethylene glycol in film coalescence aid is with the organic mercury in Fang Mildew agent.Emulsion paint be take water as thinner, be a kind of easy construction, safe, water-fastness, good permeability coating, it can mix according to different scheme of colo(u)r different color and lusters.Kind: water-based inner wall paint, oiliness interior wall paint, dry powder type interior wall paint, belong to water-borne coatings, mainly by water, emulsion, pigment, filler, five kinds of compositions of additive form.And universal along with humanity concept, and the formation of novel harmonious society, the silicon sol interior wall coating that designs a kind of water tolerance and resistance to xerotripsis excellence is very important.
