Abstract
The present invention provides a kind of aspartate high-strength weather-resistant waterproof finishing coats and preparation method thereof, are related to technical field of coatings, especially macromolecule organic coating.The program is for waterproof finishing coat poor mechanical property in the prior art, the problems such as construction is not easy, and novel waterproof finishing coat is formed by main component of polyaspartic ester resin, titanium dioxide, barium sulfate, toner, dispersant, anti-settling agent, antifoaming agent, levelling agent, coupling agent, ultra-violet absorber and curing agent.Waterproof finishing coat in the present invention is weather-proof good, excellent in mechanical performance, can be not necessarily to add any solvent during coating application, and airless spraying, roller coating and batch a variety of forms of construction work of painting, lifting construction efficiency may be implemented.
Description
Technical field
The present invention relates to macromolecule organic coating technical fields, refer in particular to a kind of aspartate high-strength weather-resistant
Waterproof finishing coat and preparation method thereof.
Background technology
Currently, water-repellent paint mainly has solvent type water-proof system and no-solvent type water-proof system in the prior art.Traditional
Polyurethane water-proof belongs to solvent type water-proof system, and coating solid part content is low, and solvent volatile quantity is big, the mechanical property of paint film
Difference, the case where being susceptible to cracking, fall off.No-solvent type water-proof system mainly has a mono-component polyurethane at present, single-component polyurea,
Aqueous polyurethane water-repellent paint and spray polyurea.The single-component polyurea cost of raw material is high, and at least contains 15%- in system
20% organic solvent can only pass through roller coating or batch painting construction.The hydrolytic resistance and mechanical property of aqueous polyurethane water-repellent paint
It can be poor relative to oiliness.Spray polyurea water-proof system needs special spraying equipment that could construct, and rate of drying is led very much soon
It causes to be easy to fall off with base material poor adhesive force, paint film.
Invention content
The technical problem to be solved by the present invention is to：The bottleneck for overcoming the prior art is developed a kind of with more excellent
Mechanical property, compared with low viscosity, be easy to the new waterproof finishing coat of construction usage.
In order to solve the above-mentioned technical problem, the invention discloses a kind of aspartate high-strength weather-resistant waterproof surfaces
Paint, the finishing coat by with the use of component A and B component form, by weight,
The component A includes：30-90 parts of polyaspartic ester resin, 10-30 parts of titanium dioxide, 10-20 parts of barium sulfate,
1-10 parts of toner, 0.1-0.5 parts of dispersant, 0.5-3 parts of anti-settling agent, 0.1-1 parts of antifoaming agent, 0.1-0.2 parts of levelling agent, coupling agent
1-5 parts, 1-2 parts of ultra-violet absorber；
The B component is curing agent, and parts by weight are 80-200 parts.
Further, the aspartate high-strength weather-resistant waterproof finishing coat by with the use of component A and B component
Composition, by weight,
The component A includes：57 parts of polyaspartic ester resin, 16 parts of titanium dioxide, 17 parts of barium sulfate, toner 6 part, point
0.3 part of powder, 1.1 parts of anti-settling agent, 0.5 part of antifoaming agent, 0.1 part of levelling agent, 1 part of coupling agent, 1 part of ultra-violet absorber；

The B component is curing agent, and parts by weight are 80-200 parts.Specific embodiment is as follows：
Embodiment 1
A kind of aspartate high-strength weather-resistant waterproof finishing coat, including component A and B component.
Component A includes：
B component：
72 parts by weight of decanedioic acid 3- methyl 1,5- pentanediols polyester polyol
16 parts by weight of isophorone diisocyanate
10 parts by weight of dicyclohexyl methyl hydride diisocyanate
B component NCO% is 6.2%
In use, by component A and B component proportionally 1：1.4 are uniformly mixed and can construct.
Wherein, the preparation method of component A is：Titanium is added into polyaspartic ester resin according to above-mentioned each parts by weight
White powder, barium sulfate, toner, dispersant, anti-settling agent, antifoaming agent, levelling agent, coupling agent, ultra-violet absorber simultaneously stir evenly i.e.

Wherein, the preparation method of B component curing agent is：By raw material decanedioic acid 3- methyl 1,5- pentanediols polyester polyol,
Isophorone diisocyanate and dicyclohexyl methyl hydride diisocyanate are mixed evenly by the parts by weight, and in 80
Heat preservation drops to 6.2% to NCO% in system and can be obtained curing agent B component at DEG C.
Because above-mentioned formula belongs to water-repellent paint topcoat formulation, coating need preferable mechanical property, surface effect, with
And weather-proof, chemical resistance.Coating raw material formula is selected according to above requirement.It is to use poly-aspartic-acid first
Based on ester resin, elastic cured dose synthesized with saturated polyester provides excellent mechanics and weather resistance for coating.With dispersion
Agent, levelling agent, antifoaming agent provide coating excellent surface effect.Other powders and auxiliary agent selection are with reference to as follows.
For titanium dioxide as a kind of white pigment, tinting strength, tinting power is good, and surface wettability is good, is easily dispersed.
Barium sulfate is white or linen crystalline powder, has chemical inertness strong, and stability is good, and acid and alkali-resistance, density is big,
Hardness is moderate, and proportion is high, high whiteness, the advantages that capable of absorbing harm ray.Therefore barium sulfate is big better than other for top coat
Most fillers.
Anti-settling agent generally selects aerosil, grain size very little, therefore large specific surface area, and superficial attractive forces are strong, table
Face can be big, and chemical purity is high, and dispersion performance is good.Stability, thickening property and the thixotropy of coating storage can be enhanced in coating,
With anti-sedimentation effect.
Coupling agent is a kind of substance having there are two types of heterogeneity functional group, and the maximum feature of molecular structure is in molecule
Containing two different groups of chemical property, one be close inorganic matter group, easily with mineral surfaces chemically reactive；It is another
A is organophilic group, chemical reaction can occur or generate hydrogen bond with synthetic resin or other polymer to be dissolved in wherein.Cause
This coupling agent is referred to as " molecular bridge ", compound to greatly improve to improve the interface interaction between inorganic matter and organic matter
The performance of material.This programme may be used such as silicone coupling agents, and the principle using siloxanes chance water hydrolytic polymerization enhances coating
With the adhesive force of base material.
Ultra-violet absorber is a kind of light stabilizer, can absorb the ultraviolet part in sunlight and fluorescent light source, and in itself
It does not change again.This programme topcoat formulation may be used such as 3- [3- (2-H- benzotriazole -2- bases) -4- hydroxyl -5- tertiary butyls
Phenyl]-propionic acid-macrogol ester and bis- (1,2,2,6,6- pentamethyl -4- piperidyls) two kinds of light stabilizers of sebacate
Mixing has superpower weather resistance and stability.
In addition, in the preparation of B component curing agent, the purpose of being down to predetermined NCO% is to allow two isocyanide of isophorone
The monomer of acid esters fully reacts, and cannot have the presence of isophorone diisocyanate monomer during coating use, because right
In the effect that human body is toxic.
In hardener formula, saturated polyol polyester is soft chain, and isocyanate-monomer is hard chain.Soft or hard chain is according to different
Ratio mixes so that the crosslink density of curing agent increases.The mechanical property for the coating that curing agent is mixed with paint could have
There is excellent effect.
