Description
Technical field
The present invention relates to polyurethane water-proof paint fields.In particular it relates to which a kind of monocomponent polyurethane waterproof applies
Material, a kind of method preparing single-component polyurethane water-proof paint and a kind of group being used to prepare the single-component polyurethane water-proof paint
Close object.
Background technology
The proposition of Green Chemistry makes we have seen that the brighter future of the mankind.Green Chemistry is also known as Environmental benign chemistry, ring
The friendly chemistry in border, cleaning chemistry, corresponding technology are also known as green technology.Corresponding product is also known as green product.In China,
The developing direction of architectural chemistry conduct industry is：Water-borne modification, high solid differentiation and Non-toxic.Regardless of a kind of substance be it is toxic,
It, which must only enter in organism, can just work, this is known as bioavilability.Bioavilability is smaller, and harm is smaller.To the greatest extent
Pipe people have also looked for some effective solution methods to the pollution problem of chemical products, but thoroughly to solve chemicals pair
The harm of human health and environment for human survival also needs us constantly to produce the substitute of toxic chemical --- green
Chemical products.
Waterproof material should be sent out in the greenization of product, Non-toxic change certainly as the major class in architectural chemistry product
Wave oneself due effect.For As-Is, although various waterproof materials emerge one after another, wherein most production
Product also greatly differ from each other from greenization.
Polyurethane water-proof paint is a kind of potentially possible Green Chemistry product.Polyurethane water-proof paint has 40 in China
The applicating history in or so year, thus have become a ripe technology in production, design and construction etc..National chemical building material
' 95 ' plans and development planning outlines in 2010 and ' 15 ' plans are all classified as polyurethane water-proof paint and give priority to
Water-repellent paint kind successively promulgates national building material industry standard JC/T500-92《Polyurethane water-proof paint》With standard GB/T/
T19250-2003《Polyurethane water-proof paint》.GB/T19250-2013《Polyurethane water-proof paint》、JC1066-2008《Building is anti-
Limits of harmful substances in water paint》.
Currently, polyurethane waterproof material in the market is divided into one-pack type polyurethane waterproof material and two-component-type polyurethane
Waterproof material.Compared with two-component type polyurethane water-proof paint, one-pack type polyurethane water-proof paint eliminates when in use to be applied
Burden process before work, without metering, proportioning, use is easy to operate；Film coated surface is smooth, bubble-free, pin hole；Applicable time
It is long.Therefore one-pack type polyurethane waterproof material exists than two-component-type polyurethane waterproof material on materials'use apparent excellent
Gesture.
Either one-pack type polyurethane waterproof material or two-component type polyurethane waterproof material, its group in conventional formulation
Point be all by polyethers, toluene di-isocyanate(TDI) (Toluene-2,4-diisocyanate, TDI), plasticizer, solvent, catalyst,
The auxiliary agents such as color stuffing and amine or alcohols curing agent composition.Wherein toluene di-isocyanate(TDI) (TDI) be it is colourless have it is strong pungent
The liquid of taste, boiling point are 251 DEG C, and proportion 1.22 meets light blackening.Since the vapour pressure of TDI is high, so using smell weight when TDI,
Toxicity is big.In addition, there are surface drying times especially to grow when the one-pack type polyurethane waterproof material winter containing TDI constructs, it is certainly real
The dry time is also extremely long, long so as to cause the winter construction duration.And methyl diphenylene diisocyanate (Diphenyl-
Methane-diisocyanate, MDI) at 160 DEG C, steam pressure is only that (steam pressure is just at 120 DEG C by TDI by 0.8mmHg
Reach 10mmHg, 1mmHg=133.322Pa), volatility is minimum during production and use.In addition, MOCA is anti-as polyurethane
The crosslinking agent of water paint has carcinogenesis by strong suspicion.Therefore, requirement of the people based on green product be increasingly
It mostly is considered as using water as the one-pack type polyurethane water-proof paint based on MDI of crosslinking agent.
In addition, the organotin, the organolead catalysts that contain in polyurethane waterproof material currently on the market are more toxic, and
And content is also very high in the formula having.The organic bismuth catalyst developed recently has been obtained in terms of the requirement of green product
Prodigious development.
However, it is generally the case that for the poly- ammonia of one-pack type without solvent and the use MDI more environmentally friendly relative to TDI
The viscosity of ester water-repellent paint, the material is very big, and surface drying time is still longer, this make the material in winter can application property obtain not
To guarantee, so that the application of this preferred water-repellent paint is extremely restricted.
