Abstract
The invention discloses a nano modified abrasion resistant polyurethane varnish. Components of the polyurethane varnish comprise 30-45% of hydroxyl-containing acrylic resin, 10-30% of hydroxyl-containing polyester resin, 20-30% of HDI trimer, 1-5% of polyether modified organosiloxane, 2-10% of a nano filling material and 2-5% of a polyurethane modified wetting-dispersing agent. The nano modified abrasion resistant polyurethane varnish consisting of the components has no obvious difference in workability compared with the normal polyurethane varnish, has stronger mechanical friction resistance and weathering resistance, can provide comprehensive protection and good decorative effect for products, and is safe and environmentally friendly.
Description
Technical field
The present invention relates to a kind of organic coating, particularly a kind of polyurethane lacquer.
Background technology
Most of Industrial products all can be extensive use of organic coating and carry out external coating, decorating and protecting is two big purposes of application, the motorcycle surface relies on transparent varnish to carry out decorative appearance, it is domestic that what generally adopt is polyurethane lacquer, the plentiful light of appearance of film, improve product specification greatly, have extremely strong ornamental.Two large problems puzzlement application circle is arranged at present: the one, the organic coating film long-term exposure is out of doors the time, be subjected to sunlight easily, especially ultraviolet destruction and produce free radical, and then destroy organic polymer segment in filming, produce problems such as loss of gloss efflorescence, not only influence outward appearance, serious also can cause filming peel off the protectiveness of forfeiture to body; The 2nd, when cleaning locomotive,, have a strong impact on outward appearance because early stage loss of gloss, especially dark color that problems such as dust friction cause filming are filmed more obviously.For addressing the above problem; the organic polymer photostabilizer of generally taking in the row at present to add benzo three file classes reduces the destruction of light to filming; this auxiliary agent has good assimilation effect for the ultraviolet ray of 300～400 nano wave lengths; shortcoming is to have certain ageing; simultaneously can't prevent the destruction of mechanical friction to filming; the more important thing is that for the purpose of environment protection, more and more countries (as Japan and Germany) is classified benzo three files as banned substance and forbidden to use in any field.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of nano modified abrasion resistant polyurethane varnish, has stronger anti-mechanical friction performance and weather resistance, and safety and environmental protection.
In order to solve the problems of the technologies described above, a kind of nano modified abrasion resistant polyurethane varnish of the present invention, the component of described polyurethane lacquer comprises: hydroxy acryl acid resin 30～45%, hydroxyl group containing polyester resin 10～30%, HDI tripolymer 20～30%, organic silicon modified by polyether oxygen alkane 1～5%, Nano filling 2～10%, polyurethane-modified wetting dispersing agent 2～5%.
As improvement of the technical scheme, the component of described polyurethane lacquer also comprises dimethylbenzene 3～10%.
As further improvement in the technical proposal, the component of described polyurethane lacquer also comprises butyl ester 3～10%.
The invention has the beneficial effects as follows: the nano modified abrasion resistant polyurethane varnish of employing said components is compared workability with common polyurethane lacquer is not had obvious difference; have stronger anti-mechanical friction performance and weather resistance; can be for product provide thorough protection and good decoration effect, and safety and environmental protection.
Embodiment
A kind of nano modified abrasion resistant polyurethane varnish of the present invention, the component of described polyurethane lacquer comprises: hydroxy acryl acid resin 30～45%, hydroxyl group containing polyester resin 10～30%, HDI tripolymer 20～30%, organic silicon modified by polyether oxygen alkane 1～5%, Nano filling 2～10%, polyurethane-modified wetting dispersing agent 2～5%; The component of described polyurethane lacquer also comprises dimethylbenzene 3～10%; The component of described polyurethane lacquer also comprises butyl ester 3～10%.Wherein hydroxy acryl acid resin, hydroxyl group containing polyester resin and HDI tripolymer are filmogens, organic silicon modified by polyether oxygen alkane is leveling auxiliary agent, Nano filling is the wear-resisting scratch-resisting auxiliary agent, and polyurethane-modified wetting dispersing agent is to be used for the stabilized nanoscale filler, and dimethylbenzene and butyl ester are thinners.
Adopt the nano modified abrasion resistant polyurethane varnish of said components to be widely used in motorcycle application, car repair and bumper field of coating; compare workability with common polyurethane lacquer and do not have obvious difference; have stronger anti-mechanical friction performance and weather resistance; can be with solving conventional polyurethanes varnish because not washability and the early stage loss of gloss that causes and weather resistance deviation and the problem of the middle and later periods loss of gloss that occurs; can be for product provide thorough protection and good decoration effect, and safety and environmental protection.
(full spectral light is about 2160MJ/m according to energy in the weathering resistance test of 1000h
2, be equivalent to the solar radiation energy that outdoor use was accepted in 2 years), the problem of early stage loss of gloss or middle and later periods loss of gloss does not appear.Below be the performance comparison of nano modified abrasion resistant polyurethane varnish of the present invention and conventional polyurethanes varnish:
| Film performance and testing method | Conventional polyurethanes varnish | Nano modified abrasion resistant polyurethane varnish |
| Hardness | B | H |
| Impact (Kg.cm) | >50 | >50 |
| Visible light transmissivity | >95％ | >95％ |
| Water tolerance | 240h | 1000h |
| Anti-dimethylbenzene wiping | 10 times | 30 times |
| Washability (100 times) | Protect light rate 70% | Protect light rate 90% |
| Weathering resistance | 1000H | >2000H |
