Description
Technical field
The present invention relates to building material field, more particularly to a kind of color modified water-repellent paint.
Background technology
With the enhancing of people's environmental consciousness, water paint has become the hot product in 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, all 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, and the initial stage seventies occurs 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, with the technological approaches that high polymer is modified, in the longer history of China, its raw material comes
Source is extensive, and cost is relatively low, it is adaptable to measure the general waterproofing work of big face light；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 is easily because the humidity of in the air is not enough caused
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 due to material component complexity, 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.With environmental protection concept
Strengthen the appearance with environmental regulation, the GB/T 19,250 2013 of the enforcement on the 1st of August in 2014《Polyurethane water-proof paint》Middle increase
Limits of harmful substances, now direction of the polyurethane water-proof paint just towards environmental protection, health develop.Therefore, develop a kind of new
Modified water-proof coating with water-tolerant environment-protecting asepsis, remains the important topic of people's research.
Present water-repellent paint, is specifically designed for the weatherability of water-repellent paint and heat-resisting Journal of Sex Research can be found everywhere, and utilizes now
Nano material can improve weatherability and the water resistance of coating, such as Chinese patent CN as the raw material of waterproof material
Disclosed in 105254234A《A kind of double-component aqueous Nano waterproof paint and preparation method thereof》, but cost is high, using double
Component is limited by field condition during use again due to material component complexity, and difficult quality is stable；Also have using change pigment and fill out
The formula of material is improving heat resistance and the decorative cover of the coating being prepared into, but its technological process complexity for preparing, it is desirable to relatively
Height, and unreasonable stain resistance of arranging in pairs or groups is poor, causes to lose the effect of heat-insulating decorative.
