Abstract
The invention relates to the technical field of aqueous finishing coats and particularly provides a high-performance aqueous UV finishing coat and a preparation method thereof. The aqueous UV finishing coat includes following components, by mass, 5-35% of an aliphatic polyurethane-acrylic acid co-polymer emulsion, 58-88% of a polyurethane dispersion, 1-15% of a high-elastic polyurethane dispersion, 0.2-0.5% of a polysiloxane mixture, 0.1-0.3% of a polysiloxane mixture and 0-3% of precipitated silica which is subjected to surface organic treatment. In the invention, by means of combination of the three aqueous resins, including the aliphatic polyurethane-acrylic acid co-polymer emulsion, the polyurethane dispersion and the high-elastic polyurethane dispersion, a coating film of the aqueous UV finishing coat is higher in transparency, is quick to dry and is easy to polish when compared with a product in the prior art. The aqueous UV finishing coat is excellent in environment-friendly property due to very-low TVOC and is a representative energy-saving and environment-protecting product which is strongly advocated in our country.
Description
Technical field
The present invention relates to aqueous finish paint technical field, specifically a kind of high-performance water-based UV finish paint and preparation method thereof.
Background technology
Water-based UV finish paint product is desirable solidifying product, has outstanding plane spraying effect.Be coated with attractive in appearance, the silk of facing sliding fine and smooth, filling properties is good, operational safety is simple, pollution-free; The features such as be mainly used in timber floor aspect to environment this product that has no adverse effect, have fillibility good, transparency is strong, and hardness is high, and cost performance is good, easy sanding, and environmental-protecting performance is excellent.Existing water-based UV finish paint, low, the dry feature of slowly, not easily polishing of transparency, to special base material, as the timber, plastic cement etc. of polyurethane foam material, high grease, there is the problem of base material difficulty attachment, the hardness of paint film is not high, easily cause sagging, paint film flexibility is bad, well can not comply with the flexible of base material, easily cause cracking and repeatedly after recoat paint film easy to crack, also there is the plastic cement materials such as ABS, PC, PS are easily stung end problem by solvent.
Therefore, for overcoming the deficiency of above-mentioned technology and designing a paint film and have that transparency is high, fast drying, easily to polish, the problem of special base material difficulty attachment can be solved, the cross-linking density of film forming matter is high, thus significantly promote the hardness of paint film and anti-performance of sinking, paint film is heat-resisting, water-fast, the high-performance water-based UV finish paint of the one of excellent chemical resistance and preparation method thereof, contriver's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide a kind of high-performance water-based UV finish paint and preparation method thereof, its paint film has that transparency is high, fast drying, easily polish, the problem of special base material difficulty attachment can be solved, the cross-linking density of film forming matter is high, thus significantly promoting the hardness of paint film and anti-performance of sinking, paint film is heat-resisting, water-fast, excellent chemical resistance, has extraordinary practical value.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-performance water-based UV finish paint, it is characterized in that formula is in mass ratio:
First part's component:
Second section component:
Alpha-alcohol ketone 0.4-0.8%
Benzoyl formiate 0.1-0.4%
1-Methoxy-2-propyl acetate 0.3-0.6%
Part III component:
The preparation method of above-mentioned a kind of high-performance water-based UV finish paint comprises following steps:
Step one: be uniformly mixed 10 minutes with rotating speed 800RPM after adding with above-mentioned first part six components;
Step 2: by first for second section three components premix, and then slowly add under rotating speed 1000-1200RPM stirs, disperse 20 minutes;
Step 3: Part III five components are added under rotating speed 800-1000RPM stirs, disperses 20 minutes.
The invention has the beneficial effects as follows:
1, this invention formula adopts the collocation of aliphatic polyurethane acroleic acid interpolymer latex emulsion, polyurethane dispersions and high resilience polyurethane dispersion three kinds of water-base resins, compared with existing product of the same trade paint film have that transparency is high, fast drying, the feature of easily polishing.
2, to special base material, as the timber, plastic cement etc. of polyurethane foam material, high grease, there are good sticking power and adaptability widely, solve the problem of above-mentioned base material difficulty attachment.
3, the cross-linking density of film forming matter is high, thus significantly promotes the hardness of paint film and anti-performance of sinking, and paint film is heat-resisting, water-fast, excellent chemical resistance.
The high resilience polyurethane dispersion of 4, arranging in pairs or groups appropriate, guarantees that paint film flexibility is good, well can comply with the flexible of base material, prevents from ftractureing and problem that repeatedly paint film is easy to crack after recoat.
5, owing to being Water-borne modification product, the plastic cement materials such as ABS, PC, PS are easily stung end problem by solvent is solved.
6, extremely low TVOC has splendid environment friendly, and it is energy-conservation to be that country vigorously advocates at present, the mainstream product of environmentfriendly products.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further, should be understood that these embodiments are only not used in for illustration of the present invention and limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values drop on application appended claims limited range equally.
A kind of high-performance water-based UV finish paint, the formula of concrete mass ratio and preparation method are:
Step one, with rotating speed 800RPM is uniformly mixed 10 minute after adding with above-mentioned first part six components;
Alpha-alcohol ketone 0.4-0.8%
Benzoyl formiate 0.1-0.4%
1-Methoxy-2-propyl acetate 0.3-0.6%
Step 2, by first for second section three components premixs, and then slowly to add under rotating speed 1000-1200RPM stirs, disperse 20 minutes;
