Description

A kind of sprayed coating and its spraying method of haze fine definition
Technical field
The invention belongs to sprayed coating and its spraying side of technical field of coatings, more particularly to a kind of haze fine definition Method.
Background technology
With the continuous improvement of people's living standards, people are to the outer of some electronic products, electrical equipment, equipment, ornament etc. Sight requires more and more higher, at present, on display coversheet or some decorative appearances, usually using matte appearance.At present, outside cloudy surface The realization of sight mainly has two methods:
(1)It is coated with the surface of transparent base in last layer film layer, film and is dispersed with silicon dioxide granule, the dioxy SiClx is used as flatting silica, utilizes the silicon dioxide granule disperseed in film so that the surface of film has concavo-convex fluctuating, profit Light is scattered with this ups and downs surface, thereby to reach the appearance of cloudy surface.
(2)Last layer film layer is coated with the surface of transparent base, film surface is imprinted into out concavo-convex fluctuating using mould, Light is scattered using this ups and downs surface, thereby to reach the appearance of cloudy surface.
But, in above two method, no matter which kind of method, in haze change, the optics such as its glossiness and definition Property still suffers from the limitation of many.Particularly under the outward appearance demand of haze, it is impossible to reach the visual effect of fine definition.Cause This, is having appearance Tong Time concurrently, how to lift the optical characteristics of film, be current a great problem.

As a further improvement on the present invention, the sprayed coating of the haze fine definition also includes dispersant, stably At least one of agent, light trigger or solvent.
Present invention also offers a kind of spraying method of the sprayed coating using haze fine definition as described above, bag Include following steps:Workpiece to be sprayed is put on spraying equipment board, under enclosed environment, using described haze high definition The sprayed coating of clear degree is sprayed on the surface of bottom material of workpiece, and spraying thickness is 2 ~ 20 μm;By the good workpiece of surface spraying Toasted.
As a further improvement on the present invention, provided with atomization mouth in the spray gun of the spraying equipment.It is preferred that, the spraying Equipment is provided with filter screen.
As a further improvement on the present invention, the resin is photosensitive resin, and the spraying of the haze fine definition is applied Material also includes light trigger, after workpiece surface spraying is good, workpiece is baked into surface drying with infrared ray at 60 ~ 80 DEG C, so Carry out curing reaction under ultraviolet light afterwards, finally toasted 10 ~ 60 minutes at 60 ~ 80 DEG C.Using this technical scheme, nothing Solvent discharge, safety non-pollution;Hardening time is short, and solidification temperature is low, and volatile matter is low, saves the energy, simple to operate.
It is preferred that, the time that workpiece is toasted at 60 ~ 80 DEG C with infrared ray is 3 ~ 10 minutes.
It is preferred that, the intensity of the ultraviolet light is 300 ~ 1000 mJ.
It is preferred that, the Facing material of the workpiece is lucite PMMA, PC or glass.
Compared with prior art, beneficial effects of the present invention are:It is high in the haze using technical scheme In the sprayed coating of definition, the filler of solid particle and hollow granule is arranged in pairs or groups, it is mixed into resin, using micro- The change of kernel structure and the difference of refractive index cause the optical phenomenas such as the scattering, refraction and reflection of light, apply the surface of workpiece Layer still ensures that the visual effect of fine definition under the visual condition for realizing haze.
