Abstract
The invention discloses a self-repairing waterborne woodware finishing coat, which is prepared from the following raw materials in parts by weight: 55-75 parts of self-crosslinked polyacrylic modified polyurethane resin, 0-10 parts of a pigment, 4-10 parts of a nano self-repairing assistant, 1-3 parts of nano silica dispersion, 2-8 parts of a coalescing agent, 0.75-3.1 parts of a function additive and 5-15 parts of water. According to the self-repairing waterborne woodware finishing coat designed aiming at the problems that the current waterborne paint is low in hardness, poor in scratch resistance and the like, self-repairing of micro cracks on the woodware surface can be achieved; the service life of the woodware is prolonged; and meanwhile, artificial repairing is avoided.
Description
Technical field
The present invention relates to technical field of coatings, particularly relate to a kind of selfreparing aqueous wooden ware finish paint.
Background technology
Woodenware use or handling process in scratched unavoidably, cause scuffing crackle to a certain degree, or envrionment temperature and humidity change paint film there is crackle, these not only affect the attractive in appearance of woodenware, also can make reduce its work-ing life.
In recent years, world wide ecotope constantly worsens, government for environmental protection pay attention to day by day, environmental regulation day by day improve and strict, in the use of wood lacquer, water-miscible paint development is rapidly.Compared to traditional solvent-thinned paint, water-miscible paint has good environmental protection characteristic, low or Diamond Search discharge, pollution-free, to human body fanout free region, more meets the pursuit of modern.Aqueous woodware paint is using water as solvent, hydrophilic resin, as filmogen, is present in water in paint film and auxiliary agent plays plastification after film forming, therefore make hardness of paint film not high, resistance to marring and wearing no resistance, thus preparation has, and to scratch tiny crack selfreparing aqueous woodware paint significant.
Summary of the invention
Based on this, the object of this invention is to provide a kind of selfreparing aqueous wooden ware finish paint, this coating can strengthen the anti-zoned wear resistance on woodenware surface, has self-healing properties for fine crack.
Concrete technical scheme is as follows:
A kind of selfreparing aqueous wooden ware finish paint, is prepared from by the raw material of following weight part:
Wherein in an embodiment, selfreparing aqueous wooden ware finish paint is prepared from by the raw material of following weight part:
An embodiment wherein, the solid content of described self-crosslinking acrylic modified polyurethane resin is 40% ~ 50%.
Wherein in an embodiment, described nanometer selfreparing auxiliary agent be selected from nanometer selfreparing auxiliary agent A, nanometer selfreparing auxiliary agent B one or both, be respectively DA305 and DA607 of ToNa company.
Wherein in an embodiment, the particle diameter of described Nano silicon dioxide dispersion is 10-20nm.
Wherein in an embodiment, described functional agent is wetting agent, defoamer, dispersion agent, flow agent, photostabilizer and sanitas.
Wherein in an embodiment, functional agent is made up of the component of following weight part:
Principle of the present invention is as follows:
Principle of the present invention mainly comprises three aspects: adopt on the one hand self-crosslinking acrylic modified polyurethane as filmogen, has not only had acrylic acid rigidity but also has had the toughness of urethane, made paint vehicle have good surface property; Second aspect adds Nano silicon dioxide dispersion, significantly improves the hardness of paint film, intensity and scratch resistance, improves sticking power simultaneously; The third aspect adds selfreparing auxiliary agent, can when paint film sustains damage reparation.
The present invention has the following advantages:
(1) compared to traditional solvent-borne lacquer as woodenware finish, contained by the present invention, harmful substances obviously reduces, and it is even zero that VOC content significantly reduces, and free formaldehyde, TDI significantly reduce, and is high-efficiency environment friendly coating, harmless for Health Status For Workers Exposed.
(2) the present invention is directed to current water-miscible paint hardness low, the problem design preparation selfreparing aqueous wooden ware finish paints such as resistance to marring difference, can realize the fine crack selfreparing of woodenware surface, extend the work-ing life of woodenware, avoid artificial reparation simultaneously.
(3) advantages such as preparation method of the present invention is simple, and the paint vehicle obtained has that hardness is high, good springiness, weathering resistance strong, construction is simple, seasoning, usability are strong.
