Abstract
The invention provides an aliphatic polyurea coating. The coating comprises the following components in a mass ratio of: 630-670 parts pf hybrid hindered amine adduct(HybridHAA), 2.5-4 parts of color pastes, 140-160 parts of titanium dioxide, 55-60 parts of silane treated calcium metasilicate, 4-6 parts of defoamers, 45-50 parts of aspartic acid ester amine, and 55-60 parts of polyoxypropylene diamine. The components are mixed according to the ratio, ground at a high speed to 6N.s, then added with 900-950 parts of urethane modified HDI (Hexamethylene Diisocyanate) trimers, and mixed uniformly to obtain the coating. The aliphatic polyurea coating provided by the invention has the advantages of good elongation at break and tensile strength, excellent abrasion resistance, weather resistance and strong adhesion, the capability of being sprayed manually or mechanically, no discoloring, no chalking, no blistering and no cracks after a long-term use.
Description
Technical field
The present invention relates to technical field of coatings, refer in particular to a kind of aliphatic Polyurea paint.
Background technology
The development of the development of railway, especially high-speed railway is had higher requirement to the coating that is used for railway bridge and dyes, and the property indices of the domestic fat brain family waterproof paint that railroad bridge is used has been made strict and detailed regulation.And well-known, traditional urethane (polyureas) waterproof paint mainly comprises mono-composition poyurethane water-proof paint, Two-component Waterproof Polyurethane Coating and two-component spraying type polyurea waterproof coating material.These coating use isocyanate compound as film forming matter or co-reactant, in use, xanthochromia and powder phenomenon-tion occur under physical environment due to long-term exposure, not only affect mechanical property and the work-ing life of water-proof coating.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of spraying rear without variable color, without efflorescence, non-foaming, flawless aliphatic Polyurea paint.
For achieving the above object, technical scheme provided by the present invention is: a kind of aliphatic Polyurea paint, and the mass ratio of described each component of coating is:
Add 630 ~ 670 parts of mould assembly hindered amine adducts (HybridHAA)
2.5 ~ 4 parts of mill bases
140 ~ 160 parts of titanium dioxides
55 ~ 60 parts of the calcium metasilicates that silane treatment is crossed
4 ~ 6 parts of defoamers
45 ~ 50 parts of aspartate amine
55 ~ 60 parts of polyoxypropylene diamine;
Above-mentioned formula is mixed rear speed lapping to 6Ns by proportioning, then add 900 ~ 950 parts of urethano modification HDI tripolymers, stir, and get final product.
The invention has the advantages that: the coating of this coating has good elongation at break and tensile strength, have good wear resistance, weathering resistance, strong adhesion, can adopt craft or mechanically spraying, after the coating life-time service also without variable color, without efflorescence, non-foaming, flawless.
Embodiment
Below the invention will be further described, preferred embodiment of the present invention is: the mass ratio of described each component of aliphatic Polyurea paint of the present embodiment is:
Add 639.7 parts of mould assembly hindered amine adducts (HybridHAA)
3.1 parts of mill bases
152 parts of titanium dioxides
57 parts of the calcium metasilicates that silane treatment is crossed
4.8 parts of defoamers
47.5 parts of aspartate amine
57 parts of polyoxypropylene diamine;
During preparation, the preparation method first mixes rear speed lapping with above-mentioned formula to 6Ns by proportioning routinely, then adds 930 parts of urethano modification HDI tripolymers, stirs, and get final product.
The coating of this programme coating has good elongation at break and tensile strength, has good wear resistance, weathering resistance, strong adhesion, can adopt craft or mechanically spraying.
The embodiment of the above only is the present invention's preferred embodiment, is not to limit practical range of the present invention with this, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
