Abstract
The invention provides polyurethane paint. The polyurethane paint is prepared from the following components in parts by weight: 40 to 65 parts of aliphatic polyurethane, 10 to 15 parts of hydrophilic polyisocyanate, 2 to 8 parts of acrylic acid, 2 to 10 parts of hydrophilic colloid, 1 to 5 parts of an emulsifier and 3 to 5 parts of a dispersion stabilizer. The dispersion stabilizer is sodium dodecylbenzene sulfonate and a dispersion phase can be dispersed very well in a dispersion medium; the dispersion stabilizer can also be adsorbed by surfaces of particles of the dispersion phase, so that the particles can be kept at a stable dispersion state for long time, and the paint can be prevented from being precipitated and caked in a storage process; the hydrophilic colloid is a nano super-hydrophilic light energy water solution; the polyurethane paint is constructed by adopting a spraying manner. The polyurethane paint provided by the invention has high definition and a paint system is stable; the polyurethane paint has relatively high practicability and generalization and can meet the requirements of people on high-quality paint.
Description
Technical field
The present invention relates to technical field of coatings, more particularly to a kind of polyurethane coating.
Background technology
The coating direction of the positive environment-friendly and higher performance of China Today develops, and in high-performance with both competitions being combined environment-friendly, polyurethane coating turns into one of raw material supplier's preferred product of coatings industry.Polyurethane is in the aspect excellent performance such as corrosion resistance, weatherability, scratch resistance；There is environment-friendly this characteristic simultaneously.
It is used for the polyurethanes technology of coatings industry in China（Do not include building coating）Shared ratio is more than 25%.Polyurethane coating is occupied an leading position in woodwork coating industry, accounts for 75% market share, and followed by car refinishing paint, it accounts for the market share more than 40%.Application of the polyurethanes technology in terms of anticorrosive paint, plastic paint and original factory of vehicle paint is also increasing, accounts for 10% market share.Recently, polyurethane coating is just being increased in Chinese Coating Market with 15% average growth rate.
Polyurethane coating has that weathering is good, gloss retention is good, color stability is good, corrosion-resistant, acid rain resistant, low temperature application performance are good, it is good that coating can cover painting performance, easily repair, good film flexibility simultaneously has excellent ductility, impact resistance and the good performance advantage of anti-vibration effect, and its remarkable combination property makes it be widely used in antiseptic project.
In general, aqueous polyurethane coating need not additionally add emulsifying agent or dispersant, because its molecular structure and size can carry out flexible modulation according to performance.Compared with latex paint, with more preferable film formation at low temp characteristic, it is not necessary to extra addition coalescents or plasticizer.The film of aqueous polyurethane coating has good tack to nearly all conventional base material, with outstanding durability and impact resistance.Furthermore it is possible to strengthen its solvent resistant and chemical-resistant, and be made the film of bloom come modified aqueous polyurethane coating by cross-linking reaction.Therefore, aqueous dispersion aqueous polyurethane coating has a wide range of applications field.
The content of the invention
It is an object of the invention to provide a kind of easy construction, there is the polyurethane coating of fabulous adhesive force and chemical-resistant.
To realize above-mentioned purpose of the invention, the present invention provides a kind of polyurethane coating, is made up of the component of following parts by weight：Aliphatic polyurethane 40-65 parts, 10-15 parts, acrylic acid 2-8 parts, hydrophilic colloid 2-10 parts, emulsifying agent 1-5 parts, dispersion stabilizer 3-5 parts of hydrophily PIC.
The dispersion stabilizer is neopelex, and dispersed phase can be made to disperse very well in decentralized medium, can also enable these particles muchly in the dispersity of stabilization by dispersion particle adsorption, is precipitated when can prevent coating from storing, lumpd.
The hydrophilic colloid is the super hydrophilic luminous energy aqueous solution of nanometer.
The polyurethane coating is constructed using spraying method.
Beneficial effects of the present invention compared with prior art.
The polyurethane coating that the present invention is provided, definition is high, coating system is stable, with stronger practicality and generalization, disclosure satisfy that demand of the people to high-quality coating.
Specific embodiment
The present invention is further described with reference to specific embodiment.
Embodiment 1.
The present embodiment provides a kind of polyurethane coating, is made up of the component of following parts by weight：50 parts of aliphatic polyurethane, 12 parts of hydrophily PIC, 5 parts of acrylic acid, 8 parts of hydrophilic colloid, 2 parts of emulsifying agent, 3.5 parts of dispersion stabilizer.
The dispersion stabilizer is neopelex, and dispersed phase can be made to disperse very well in decentralized medium, can also enable these particles muchly in the dispersity of stabilization by dispersion particle adsorption, is precipitated when can prevent coating from storing, lumpd.
The hydrophilic colloid is the super hydrophilic luminous energy aqueous solution of nanometer.
The polyurethane coating that the present embodiment is provided, the thickness that can once construct needed for obtaining, it is easier to construct.For from performance, aliphatic polyurethane spray system for roofing have high intensity, it is seamless, can walk, the characteristic such as anti-plant roots are penetrated, chemicals-resistant, can possess excellent weatherability, there is provided relatively long-term protection, and easily safeguard.
The polyurethane coating is constructed using spraying method.Specifically construction technology is：Cleaning basic unit：Basic unit is cleaned up；Basic unit should accomplish to look for slope accurate, and draining is smooth, surfacing, it is solid, without playing ash, a dusting, flake and the phenomenon such as ftracture.Before brushing base treatment agent, substrate surface should reach drying regime.It is polyurethane coating is correct deployed and stir, spray one time, want thickness consistent during operation.After after the drying of first pass coating curing of coating, to scrape method painting by first pass painting and scrape second time coating.Coating blade coating direction should be perpendicular with first pass, and material quantity is identical with first pass.
The polyurethane coating is stored in drying, ventilation, shady place, and the shelf-life, oneself did not broke seal 6 months from producing；Transport is handled by non-dangerous article.
The polyurethane coating must be stored in dry, ventilation warehouse, Storage period 1 year.
The polyurethane coating is applied to roofing and toilet bath room, basement, cistern, the waterproof of metope, antiseepage, protection against the tide.
