Description
Technical field
The present invention relates to technical field of aqueous paint, particularly relate to a kind of environment-friendly type multiple-effect nano-waterborne coating.
Background technology
Building trade water-proof material used is generally divided into three major types: coiled material class, solvent based, pitch ointment class.But all there is high temperature trickling, low-temperature embrittleness, the problems such as tensile strength is low, unit elongation is little, poor adhesive force, meanwhile, three kinds of material color and lusters are black, therefore strong, the easily be full of cracks of these product heat absorptivities, aging and contaminate environment etc.And, do not accomplish the effect of seamless waterproof at all, the global problem of buildings waterproof cannot be solved.
China's existing concrete structure exterior wall major part decoration still at use exterior wall tile, exterior wall tile generally the weight of every square more than eight kilograms because the increase of wall weight has influence on the work-ing life of buildings greatly.And wall brick is non-watertight, easily come off and potential potential safety hazard.Meanwhile, a large amount of uses of wall brick are passive large to the Nonrenewable resources such as soil, coal.
In addition, solvent based coating only has single effect, does not possess the function of multiple-effect, in use must add conditioning agent again, and the content of formaldehyde and organic compound VOC is high, and digestion time is short, big for environment pollution.Meanwhile, coating is rigid, and thickness can only accomplish 0.02-0.03mm.And water-borne coatings seldom, does not fire the advantages such as not quick-fried high security, non yellowing, brushing area be large with its asepsis environment-protecting, odorlessness, volatilizable thing, along with the enhancing of people's environmental consciousness, more and more be subject to the welcome in market, but, how to make water-borne coatings have more function simultaneously, such as high resilience, waterproof, the performance such as antirust, weather-proof, thus make water-borne coatings have more wide application market, be a problem needing constantly research.
The application of nanotechnology is the mark of world technology.Nanotechnology, at the application and development of coating industry, impels coating to update, and has started breakthrough new era for coating becomes real Green Product.Nano paint has been identified as the special product of Olympic Village's construction work, shows the using value of nano paint in building field.It utilizes unique photocatalysis technology to have strong decomposition, eliminating effect to toxic gas in air.The obnoxious flavour such as PARA FORMALDEHYDE PRILLS(91,95), ammonia has the function absorbing and eliminate, and makes room air more pure and fresh.After tested, to various mould kill press down rate reach more than 99%.There is long-term mildew-resistant algae preventive effect, be suitable for the application of family, hospital, hotel and school.Nano-external wall paint, the two thin mechanism of the lotus leaf utilizing nano material binary collaborative, lower surface tension, there is high-strength sticking power, the high and flexible of hardness of paint film, excellent self-cleaning function, powerful anti-dust and the adhesive capacity of anti-foul, hydrophobicity is splendid, easily the performance of cleaning dirt.Washing fastness is more than 10000 times, and have good guarantor's light and protect look function, anti-uv-ray is extremely strong.Work-ing life reaches more than 10-15.Particle footpath is tiny, can go deep into body of wall, and the silicates material coordination reaction with metope, makes it firmly be combined into one, strong adhesion, non-scale, do not peel off, anti-aging.Its nanometer frost resistance functional paint, except possessing the various Optimality of Nano type coating, can within 0 degree Celsius to-25 degrees Celsius normal construction.Breach the precedent that building coating can not be constructed below 0 degree Celsius.And nano paint again can wet coating, has broken the regulation of building coating requirement body of wall humidity below 10%, building trade is constructed and shortens the duration, improve effect.How nanotechnology is applied to paint field processability and the more excellent product of security, needs further research.
