Description
Technical field
The invention belongs to water-repellent paint technical field, and in particular to a kind of HBS Two-component Waterproof Polyurethane Coatings and its system
Preparation Method.
Background technology
Two-component Waterproof Polyurethane Coating is widely used industrial one of with civilian waterproof material both at home and abroad at present, but by
Generally it is crosslinked using MOCA in market, containing poisonous and harmful substances such as pitch, coal tar, organic solvents, there is penetrating odor, environmental protection
Property is poor.
Because market is commonly mocha（MOCA classes）Solidification crosslinking, or contain coal tar, pitch, liquid Gu in B component
The harmful substances such as the grand resin of horse, dimethylbenzene, in process of production, material must be warmed up to 110~130 by B component with reactor
DEG C vacuum dehydration is carried out, increased the release of harmful substance, human body and environment are caused harm, meanwhile, rise gentle temperature-fall period
Alternately, 110~130 DEG C need to be warmed up to during dehydration carries out vacuum dehydration, and dehydration needs to cool to reactor water flowing after terminating
100~105 DEG C plus MOCA, also need to cool to 60 DEG C or so ability blowings, otherwise, blowing temperature high material viscosity after MOCA dissolvings
Precipitation easily is produced during small storage, this process throughput time is more long, increase the consumption of the energy and the unstability of product；
In sum, the shortcoming of prior art：
1st, B component production temperature is higher, increased the release of harmful substance；
2nd, production must be carried out in reactor, and material must be dehydrated, and such as moisture is not de- clean, will result in product unqualified；
3rd, complex process increases energy resource consumption, it is necessary to carry out water content detection, the production cycle is long.
The content of the invention
For deficiencies of the prior art, the technical problem to be solved in the present invention is：It is double how a kind of HBS is provided
Part polyurethane water-repellent paint and preparation method thereof, to solve existing weak point.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that：
A kind of HBS Two-component Waterproof Polyurethane Coatings, including two kinds of components of A, B.
Described component A is to contain isocyanates（-NCO）Prepolymer composition；Described B component is to contain hydroxyl（-
OH）Resin, plasticizer, water（H2O）The mixture constituted with other function additives.
Polyurethane water-proof paint refers to the water-repellent paint that a great deal of ammonia ester bond is contained within film, and main composition is removed and contained
Outside carbamate, it is also possible to contain ehter bond, urea bond, amido link and intermolecular hydrogen bonding.This project HBS two component polyurethane waterproofs
Coating is made up of two components, and component A is to contain isocyanates（-NCO）Prepolymer composition；B component is to contain hydroxyl（-OH）Tree
Fat, plasticizer, water（H2O）The mixture constituted with other function additives.
Preferably, the particle diameter of described B component is 60~100 μm.
Reaction principle of the invention is：
1、（1）Isocyanates and PPG reaction generation carbamate（Urethane）,（2）Urethane can also continue to and isocyanic acid
Ester reaction generation allophanate.
2nd, (1) isocyanates and the water reaction unstable carbamic acid of generation, it is decomposed into carbon dioxide and amine, (2) amine and
Excessive isocyanates reaction generation urea.(3) while with the special defoamer of polyurethane and Ca（OH）2To absorb CO2Gas prevents from applying
Film generation stomata makes film densification tough and tensile.
It is below the basic chemical equation of bi-component water-cured polyurethane waterproof coating of the present invention.
(1)R-NCO + H2O →〔R-NHCOOH〕→ R-NH2 + CO2
(2)R-NH2+ R-NCO → RNHCONHR
(3)Ca（OH）2+ CO2 → CaCO3 + H2O。

Step one：Component A production technology：
Various PPGs are weighed by proportion speed, is added in reactor, stir 5~10min, be warming up to 110~125 DEG C and take off
Water 2 hours, then cools to 65~75 DEG C；Weighed during various isocyanates and polymerization inhibitor add reactor by formula；Gradually rise
Temperature is to 80~85 DEG C of 2.5~3h of insulated and stirred；60~65 DEG C are cooled to, stop stirring sampling analysis；Cooling blowing after qualified.
Step 2：B component production technology：
During PPG, plasticizer added into agitator tank by proportioning, then by emulsifying agent with adding tank after quantitative warm water dissolving
Middle stirring, finally adds agitator tank by powder, material stirring is uniformly crossed triple-roller mill afterwards and is ground twice, adds catalyst（Can root
Added according to season）, blowing after being stirred in agitator tank below.
Step 3：By component A when using：B component=1：2（Mass ratio）Film-forming is reacted after stirring.
Compared to existing technology, the present invention has the advantages that：
