The nano zirconium dioxide used of raw lacquer of the present invention is the nano oxidized zirconium powder of Hefei Jian Kun company, and its particle size range is preferably 20-70nm.
What viscosity herein represented is specific viscosity, and namely a certain amount of sample is at a certain temperature from the time that the hole of specified diameter is flowed out, and represents with second (s).As within 40 seconds, being namely represent that raw lacquer of the present invention uses coating-4 viscosity meter (the special viscometer of coating), getting the time that 100ml raw lacquer of the present invention flows out from the hole of 4mm diameter at 25 DEG C is 40s (being coated with-4,25 DEG C).
Raw lacquer of the present invention introduces inorganic nano SiO in traditional raw lacquer
2particle, nano zirconium dioxide have the feature of high rigidity, and they are dispersed in the anti-scratch performance that effectively can improve paint film in paint film uniformly, utilize inorganic nano SiO
2the disperse enhancement of particle to the strong shielding properties of ultraviolet and particulate improves ageing resistance and other mechanical property of raw lacquer.These nanoparticles are main because their semiconductor property to the absorption of UV-light, and under ultraviolet irradiation, electronics is excited, and is caused to conduction band transitions by valence band.Meanwhile, because the small size of nanoparticle, can not only space in material for repairing, even can also and matrix resin (natural raw lacquer or refining raw lacquer) between there is the combination of certain bond energy, enhance the mechanical property of material.
The raw lacquer coating manufacture method of a kind of high rigidity of the present invention, by adding high-content nanometer silicon dioxide material, thus forming paint film, greatly improving the hardness of paint film, the paint film of gained also has excellent toughness simultaneously, therefore makes the scratch-resistant performance of coating of the present invention and wear resisting property improve.The present invention is carried out raw lacquer by methods such as the cooling to raw lacquer mixture, ultrasonic agitation and intensifications, that brings into when moisture and allotment paint in removing raw lacquer crosses multi-solvent, and nanometer silicon dioxide material enters in raw lacquer through ultrasonication by raw lacquer more uniformly simultaneously; Raw lacquer of the present invention needs to keep comparatively high temps to use in use, only has comparatively high temps just to can be made into the raw lacquer film of high rigidity.Hardness of paint film of the present invention detects by GB/T6739-1996 assay method, and hardness can reach 7H.
