Description
Technical field
A kind of the present invention relates to building material field, more particularly to the water-repellent paint that colour is heat-insulated.
Background technology
With the enhancing of people's environmental consciousness, hot product of the water paint into market, the development of China's water-repellent paint
Started from for the 60's with application, early stage, once with various chemical industry leftover bits and pieces as raw material developing products, stops because capability and performance is unstable
Only develop.In the same period, in terms of China is for asphalt configuration water-repellent paint is improved with high polymer, it has been also carried out relatively large
Work.The mid-1960s occur in that chloroprene rubber asphalt waterproofing coating, the initial stage seventies occur in that reclaimed rubber Colophonium
Water-repellent paint, and more successful application is obtained in engineering.As China synthesizes the stable development of Macromolecular materials industry, with each
The water-repellent paint that high-quality synthetic rubber and synthetic resin are developed for raw material is planted, is come into operation in the eighties in succession：As bi-component is gathered
Urethane water-repellent paint, the light water-repellent paint of esters of acrylic acid, cationic chloroprene latex asphalt waterproofing paint and silicone rubber waterproof
Coating etc., rubber asphalt class and synthesis high score subclass water-repellent paint are just occupying increasing in China's waterproofing work application
Proportion.Based on asphalt, the technological approaches that are modified with high polymer, in the longer history of China, its raw material comes
Extensively, cost is relatively low, it is adaptable to measure the general waterproofing work of big face light in source；The coating that is made based on synthesis macromolecular material,
Performance is more excellent, but price is higher；Due to building deformation, body of wall cracking reduces waterproof effect so as to cause coating surface to ftracture.Cause
This, the use of Colophonium class water-repellent paint is fewer and feweri, and polyurethane water-proof paint is due to excellent elasticity, durability, preventing
Water layer is light, working drawing review is convenient, receives many advantages, such as component can easily be accommodated, can be used for building different parts and good integrity
To attention.
At present, compared with developed countries, China's polyurethane water-proof paint overall performance is poor, and quality is also unstable.Poly- ammonia
Ester water-repellent paint divides one-component and double-component again.Mono-composition poyurethane water-proof paint easily because of air in humidity not enough cause
Hardening time is longer, schedule delays.And often using in double-composition polyurethane waterproof paint has carcinogen suspected of to human body
MOCA（3,3- bis- chloro- 4,4- diaminodiphenyl-methanes, are commonly called as mocha）As firming agent, and have containing substantial amounts of volatility
Machine solvent（Such as toluene, dimethylbenzene and coumarone indene resin etc.）, bicomponent polyurethane coating is complicated due to material component, during use
Limited by field condition again, difficult quality is stable；Though aqueous polyurethane coating meets development trend, because introducing parent in molecule
Aqueouss group, the resistance to water of its film, chemical resistance are poor, are particularly unsuitable for long-term Soaking environment.
Now water-repellent paint is not only satisfied with the performance such as water-fast, also has new requirement, mesh to heat-insulated, decoration effect
Front architectural reflective heat-insulation paint adds feature color stuffing with synthetic resin emulsion as base material with water as disperse medium（Predominantly
Sunlight reflection, radiation, obstruct class color stuffing）And auxiliary agent, through certain technical process make with reflective insulation effect
Water-repellent paint.Therefore, a kind of modified water-proof coating with water-tolerant environment-protecting asepsis is developed, and is had heat-insulated and ornamental
The water-repellent paint of energy, remains the important topic of people's research.The weatherability and thermal insulation for being specifically designed for now water-repellent paint is ground
Study carefully and can be found everywhere, the weatherability and water resistance of coating, example can be improved by the use of nano material as the raw material of waterproof material now
As disclosed in Chinese patent CN 105254234A《A kind of double-component aqueous Nano waterproof paint and preparation method thereof》But, into
This is high, using double-component as material component is complicated, is limited by field condition during use again, and difficult quality is stable；Also favourable
Improve heat resistance and the decorative cover of the coating being prepared into the formula of pigment and filler is changed, but its technique stream for preparing
Journey is complicated, it is desirable to higher, and unreasonable stain resistance of arranging in pairs or groups is poor, causes the effect for losing heat-insulating decorative.
