Abstract
The present invention relates to use polyurethane coating in a kind of car, be made up of the raw material of following weight part: aqueous polyurethane emulsion 15-50 part, fire retardant 10-20 part, flame retardant 1-10 part, flow agent 10-20 part and water 30-50 part.In car of the present invention, use polyurethane coating has the water tolerance of enhancing, can be widely used in coating in Automobile.
Description
Technical field
The present invention relates to automotive field, specifically, the present invention relates to use polyurethane coating in a kind of car.
Background technology
In recent years, along with the development of productivity and the continuous lifting of people's quality of life, aqueous polyurethane take water as primary solvent, there is pollution-free, nontoxic, the advantage such as good film-forming property, film snappiness are good, strong adhesion, just in time with people, the requirement of VOC low-emission in coating is catered to mutually, thus water-based polyurethane coating was developed rapidly in nearly decades.But the water tolerance of aqueous polyurethane coating comparatively its application & development of official post own is restricted.Therefore research and development have the significant and huge market outlook of the novel aqueous polyurethane coating of good water resistance.
Summary of the invention
The object of the present invention is to provide use polyurethane coating in a kind of car.
In order to realize object of the present invention, the invention provides use polyurethane coating in a kind of car, be made up of the raw material of following weight part: aqueous polyurethane emulsion 15-50 part, fire retardant 10-20 part, flame retardant 1-10 part, flow agent 10-20 part and water 30-50 part.
Preferably, in car of the present invention, use polyurethane coating is made up of the raw material of following weight part: aqueous polyurethane emulsion 25 parts, fire retardant 15 parts, flame retardant 8 parts, flow agent 10 parts and 45 parts, water.
More preferably, in car of the present invention in use polyurethane coating, described aqueous polyurethane emulsion is PUD-336.
In the present invention, PUD-336 can be such as commercially available prod, and it is purchased from ShangHai SiSheng polymer Materials Co., Ltd, are detail file see http://www.siwochem.com/products.asp? types=4.
More preferably, in car of the present invention in use polyurethane coating, described fire retardant is tetramethylolmethane.
More preferably, in car of the present invention in use polyurethane coating, described flame retardant has following structural:
More preferably, in car of the present invention in use polyurethane coating, described flow agent is HY-6410.In the art, HY-6410 such as can purchased from Beijing Mayor Chemical Technology Co., Ltd., and its detail file can reference: http://www.mr-chem.com/canp/product/118/2014-01-23/289.html.
Present invention also offers the material with following structural and be used as the purposes in flame retardant, described flame retardant has following structural:
In car of the present invention, use polyurethane coating has the flame retardant resistance of enhancing, can be widely used in coating in Automobile.
Embodiment
Below by way of the description of embodiment, the invention will be further described, but this is not limitation of the present invention, those skilled in the art are according to basic thought of the present invention, various amendment or improvement can be made, but only otherwise depart from basic thought of the present invention, all within the scope of the present invention.
Embodiment 1
Take tetramethylolmethane 15 kilograms,
kilogram, HY-641010 kilogram and 45 kilograms, water, add and be equipped with in the there-necked flask of agitator, after abundant stirring 30min, aqueous polyurethane emulsion PUD-33625 kilogram is added in 10 minutes, stir 50min at 500 rpm, last again with SRH high-shear homogenizing emulsifying pump at 50 DEG C, output speed 3000rpm, motor power 3kW, import and export the condition down cut 60min of dimension D N40/DN32, obtained aqueous polyurethane coating.
Embodiment 2
Prepare aqueous polyurethane coating according to the mode identical with embodiment 1, difference is not use HY-6410.
Experimental example
The flame retardant resistance of embodiment 1 coating is measured with reference to GB15442.2-1995 " big panel method ".The duration of fire resistance of the coating of embodiment 1 is 553.0 ± 2.0 seconds.
Water resistance test
According to standard GB/T/T1733-1993 " paint film water tolerance assay method " production standard sample, be immersed in the water 2/3 of sample, coating is allowed fully to contact with water, every 24h observes once, and test the result that is positioned in water after 240h, whether observe model has loss of gloss, variable color, foaming, wrinkling, the phenomenon such as to get rusty.
There is not loss of gloss, variable color, foaming, wrinkling, the phenomenon such as to get rusty through observing in the sample of embodiment 1, and the sample of embodiment 2 is observed film in water, soaked wrinkling foaming in 144 hours after 240h, and film turns white.
