Abstract
The invention discloses an impact-resistant aqueous polyurethane finishing varnish which includes following raw materials, by weight, 80-90 parts of aqueous polyurethane, 10-15 parts of epoxy acrylic resin, 3-4 parts of zinc stearate, 5-6 parts of triethanolamine, 8-15 parts of polyacrylamide, 2-4 parts of aluminium dihydrogen phosphate, 4-5 parts of zirconium sol, 6-8 parts of trimethylene ether, 3-4 parts of hydrogen peroxide, 8-10 parts of tricresyl phosphate, 2-4 parts of trichloroacetic acid, 15-20 parts of ferric hydroxide, 3-4 parts of tetraethylammonium bromide and 5-7 parts of sodium silicate. The aqueous polyurethane finishing varnish is low in smell after construction and a varnish film is good in scratch resistance, wear resistance and environment protection performance. The finishing varnish is increased in solid content so that the finishing varnish can be cured more quickly and further the cured finishing varnish is enhanced significantly in impact-resistant strength and adhesivity. In addition, the polyurethane finishing varnish is simple in production process and low in production cost.
Description
Technical field
The present invention relates to a kind of impact-resistant aqueous polyurethane clear finish, belong to technical field of coatings.
Background technology
Transparent priming is generally overlying on outside colored paint layer, for increasing brightness and the reflectance of spraying goods, plays the effect of sematic color enamelled coating simultaneously, avoids colored paint to fade and come off, reduce the thickness of colored paint layer simultaneously, make the paint film of formation more smooth; Transparent priming adhesion property is poor, and be very easily scratched, the corrosion of acid-base material is also more vulnerable to than common paint, the natural weather such as carbonic acid gas, acid rain acid mist as given off in Vehicular exhaust all can have a negative impact to transparent priming, once these foreign material drop on spraying goods and moisture in air is combined, the modified solution of corrosion transparent priming will be become, namely start after pre-heating temperature elevation chemical reaction occurs, corrode clear primer layer.
Summary of the invention
The object of the present invention is to provide a kind of impact-resistant aqueous polyurethane clear finish.
The present invention adopts following technical scheme to achieve these goals:
Impact-resistant aqueous polyurethane clear finish, the weight part of its constitutive material is: aqueous polyurethane 80-90, epoxy acrylic resin 10-15, Zinic stearas 3-4, trolamine 5-6, polyacrylamide 8-15, aluminium dihydrogen phosphate 2-4, zirconium colloidal sol 4-5, trimethylene ether 6-8, hydrogen peroxide 3-4, Tritolyl Phosphate 8-10, trichoroacetic acid(TCA) 2-4, ironic hydroxide 15-20, tetraethylammonium bromide 3-4 and water glass 5-7.
Impact-resistant aqueous polyurethane clear finish, the weight part of its constitutive material is: aqueous polyurethane 85, epoxy acrylic resin 12, Zinic stearas 3.5, trolamine 5.5, polyacrylamide 12, aluminium dihydrogen phosphate 3, zirconium colloidal sol 4.5, trimethylene ether 7, hydrogen peroxide 3.5, Tritolyl Phosphate 9, trichoroacetic acid(TCA) 3, ironic hydroxide 18, tetraethylammonium bromide 3.5 and water glass 6.
Advantage of the present invention:
Aqueous polyurethane clear finish prepared by the present invention not only construct after smell low, and paint film adhesion strength is good, wear resistance is good, good environmental protection; The present invention can improve solid content, accelerate solidification, and significantly can increase resistance to impact shock and the sticking power of the rear product of solidification; In addition, the present invention also has the advantages such as production technique is simple, production cost is low.
Embodiment
Embodiment 1: impact-resistant aqueous polyurethane clear finish, the weight part (g) of its constitutive material is: aqueous polyurethane 85, epoxy acrylic resin 12, Zinic stearas 3.5, trolamine 5.5, polyacrylamide 12, aluminium dihydrogen phosphate 3, zirconium colloidal sol 4.5, trimethylene ether 7, hydrogen peroxide 3.5, Tritolyl Phosphate 9, trichoroacetic acid(TCA) 3, ironic hydroxide 18, tetraethylammonium bromide 3.5 and water glass 6.
The above is only preferred embodiment of the present invention, is not restriction the present invention being made to any other form, and any amendment done according to technical spirit of the present invention or equivalent variations, still belong to the present invention's scope required for protection.
