Abstract
Wear-resistant nanometer coating is disclosed. The nanometer coating comprises 12-18% by mass of acrylic resin, 15-20% by mass of polyurethane resin, 0.2-0.8% by mass of a coalescing agent, 3-5% by mass of a photoinitiator, and 56-66% by mass of a liquid mixture of an organic-inorganic nanometer dispersion liquid and monomers. The liquid mixture of the organic-inorganic nanometer dispersion liquid and the monomers is mainly prepared from 10-20 wt% of nanometer particles, 0.3-0.5 wt% of a dispersant and an organic solvent through a mechanical method. A coating process mainly includes electrostatic layer-removing, automatic positioning, automatic spraying, levelling, ultraviolet light curing, cooling and film attaching for protection. The nanometer coating has advantages of a low production cost, a simple process, convenience in large-scale production, and the like. After hard case surfaces are coated with the coating, wear resistance and scratch resistance of the case surfaces can be significantly improved.
Description
Technical field
The present invention relates to a kind of coating and application thereof, more specifically to a kind of wearproof nano paint and at case
The application on bag surface.
Background technology
Growing along with nanotechnology, uses rigidity nanoparticle to improve organic coating hardness and wearability
Method gradually favored by researcher.The hardness of rigidity nano-particle is much larger than polymeric material, it is possible to
Coating hardness is promoted in a big way；And nano-particle also contributes to improve some long-acting performance of coating
(such as fatigue crack extended capability, creep resistant, weatherability, dimensional stability etc.)；Appropriate nanometer
Grain the least on coating adhesion and flexible impact, even also have use nano-particle improve polymer with
The report of base material adhesive force.Therefore, organic-inorganic nano hydridization/complex technique be considered as regulation and control and improvement have
A kind of new tool of organic coating performance.The rigidity nanometer used in organic-inorganic nano clear dope at present
Grain based on nano silicon, nano aluminium oxide, be not only because both nanoparticle structure various,
Wide material sources, cheap, hardness is higher, especially because their refraction index compares with polymeric matrix
Close, it is easy to accomplish the high grade of transparency of coating.
Due to huge specific surface area and high surface, nano-particle is all deposited with the form of micron order aggregate
?.Micron order aggregate can greatly reduce visible transparency and gloss, the mist degree of rising coating of coating.
It addition, micron order aggregate is unstable in dispersion liquid, after long-time placement, aggregate can precipitate.
Therefore, how by nano-particle uniformly, stable dispersion to coating system is the crucial section prepared of nano paint
Learn and technical problem.In terms of prior art, the process for dispersing of nano-particle mainly has sol-gel process and machinery
Blending method two kinds.During the greatest problem that sol-gel process presently, there are is gel drying, due to solvent,
Little molecule, the volatilization of water may cause Material shrinkage embrittlement.It addition, work in predecessor hydrolytic process
Acid, alkali, solvent be also possible to monomer cure process is produced impact；And sol-gel technique is typically only suitable for
In water paint, the cost of raw material is high, system impurity is more, be difficult to industry amplification.Relative to sol-gel
For method, the equipment that mechanical dispersion technology is used is good with coatings industry dispersing apparatus compatibility, technique is simple,
Nano paint can be prepared with scale；Coating matrix both can be aqueous can also be Organic substance；Nanometer is coated with
The manufacturing cost of material is the most much lower.And this method is it is further an advantage that prepare nano-particle and coating material
Synthesis carry out respectively, the form of nano-particle, size can be selected as required.
The surface of plastic products of high glaze (as resin eyeglass, cell phone keyboard, notebook panel, timber floor,
Suitcase, Automobile Coatings, canopy etc.) in use it is easily subject to scraping and cut occurs,
This has negative impact to the outward appearance of plastic, the quality of product even with performance, the most how to carry
Scratch resistance and the wearability of these surface of plastic products high become the problem that must account in actual applications.
The most conventional measure is to improve its hardness in surface of plastic products coating layer of transparent, wear-resisting coating.
Conventional transparent, wear-resistant coating include heat cured polymeric coating layer and silicone resin coating.Macromolecule is coated with
Layer (such as polyurethane) is although frosting hardness can be improved to a certain extent, but the limited extent improved,
Use needs can not be fully met under many circumstances.Silicone resin coating is higher to frosting hardness,
But silicone coatings is typically the most crisp, easily ftracture, the most very poor with the adhesive force of plastic-substrates.
