A kind of White environment-friendlywaterproof waterproof paint
Technical field
The present invention relates generally to a kind of coating, particularly relates to a kind of White environment-friendlywaterproof waterproof paint.
Background technology
Polyurethane water-proof paint is the performed polymer containing isocyanate group become through polyaddition reaction by isocyanic ester, polyethers etc., it is equipped with catalyzer, anhydrous auxiliary agent, anhydrous weighting agent, solvent etc., through the mono-composition poyurethane water-proof paint that the operations such as mixing are processed into. The feature such as such coating is reaction-curable (moisture-curable) coating, have intensity height, unit elongation is big, water resistance is good. That basic unit is out of shape is adaptable. Polyurethane water-proof paint is the single component Environmental-protecwaterproof waterproof paint of a kind of liquid state construction, is taking imported polyurethane performed polymer as basic composition, without the additive such as tar and pitch. It is the contact after fixing of the moisture in air, forms one layer in substrate surface firm tough and tensile without the seam anti-film of entirety.
Summary of the invention
The object of the invention is just to provide a kind of White environment-friendlywaterproof waterproof paint.
The present invention is achieved by the following technical solutions:
A kind of White environment-friendlywaterproof waterproof paint, it is made up of the raw material of following weight parts:
Aqueous polyurethane 90-100, titanium dioxide 10-20, mica powder 5-10, sodium silicate 3-4, coumarone indene resin 3-4,4-TBP 1-2, boric acid 2-3, sodium wolframate 3-4, tolyltriazole 1-2, dehydrated alcohol 2-3, vinyltrimethoxy silane 1-2, modified additive 3-5, polypropylene glycerol aether 0.1-0.2, deionized water 5-20;
Being made up of the raw material of following weight parts of described modified additive:
Aqueous acrylic emulsion 60-70, polyvinylpyrrolidone 4-6, Sodium Silicofluoride 2-3, dipropylene glycol butyl ether 1-2, polyacrylamide 1-2, hydroxypropyl Staragel 90V 0.1-0.2;
Above-mentioned aqueous acrylic emulsion is mixed with polyacrylamide, polyvinylpyrrolidone, Sodium Silicofluoride is added after fully stirring, 400-600 rev/min dispersed with stirring 10-20 minute, obtain dispersion liquid, dipropylene glycol butyl ether is joined in 3-4 times of water, is steam heated to 70-80 DEG C, it is added drop-wise in above-mentioned dispersion liquid, add hydroxypropyl Staragel 90V after dropwising, stir evenly, obtain described modified additive.
A preparation method for White environment-friendlywaterproof waterproof paint, comprises the following steps:
Above-mentioned tolyltriazole is joined in dehydrated alcohol, it is heated to 60-70 DEG C, fully stir, add mica powder, sodium silicate, titanium dioxide, it is cooled to normal temperature, add vinyltrimethoxy silane, 300-400 rev/min dispersed with stirring 4-5 minute, add coumarone indene resin, 4-TBP, boric acid, sodium wolframate, 500-600 rev/min dispersed with stirring 10-15 minute, aqueous polyurethane is slowly poured into, after fully stirring, add residue each raw material, 600-700 rev/min dispersed with stirring 20-25 minute, obtain described White environment-friendlywaterproof waterproof paint.
It is an advantage of the invention that:
The waterproof paint that the present invention produces is nonpoisonous and tasteless, and nonpollution environment, environmental protection, weather resisteant is good, and high temperature does not trickle, and low temperature does not chap, and has good ageing-resistant performance, and over-all properties is outstanding.
