Abstract

The invention provides a fluorocarbon-coated surface treatment process for conducting laser treatment on a metal surface. Through the process, the surface of a product is subjected to four times of spraying and four times of roasting; the surface texture is etched into the surface of a base material through lasers so that the surface texture and the surface concave-convex effect of the product can remain permanent; and moreover, because the surface of the product is coated with fluorocarbon coatings known for weather resistance, the service life of the product is further prolonged. Accordingly, the surface of the product produced through the process is more obvious in three-dimensional effect, resistant to abrasion and realistic, and space and time conversion can be further allowed, so that the durable, economical and practical effects are achieved.

Description

A kind of (fluorocarbon-sprayed) process of surface treatment carrying out laser radium in metal surface

Technical field

The present invention relates to the technical field of spraying section bar technique, refer in particular to a kind of (fluorocarbon-sprayed) process of surface treatment carrying out laser radium in metal surface.

Background technology

Know in the industry and know; conventional all section bar spraying coating process are simply put in time and energy at Surface of profile; this makes it have some limitations; hardly result in substantial variation to meet the different requirements of client; and the surface effect of product that surface spray coating process is produced also tends to be uneven; some defects often occur, and the practical time limit of most product is also comparatively short, is extremely difficult to intended beneficial effect.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, a kind of (fluorocarbon-sprayed) process of surface treatment carrying out laser radium in metal surface is provided, by this technique, the product surface stereoeffect produced is become apparent from, wear-resisting, true to nature, more can receiving space, the conversion of time, to reach prolonged, durable, economic, economical effect, breach the limitation of conventional all section bar spraying coating process, obtain substantial change.

For achieving the above object, technical scheme provided by the present invention is: a kind of (fluorocarbon-sprayed) process of surface treatment carrying out laser radium in metal surface, having main steps that of this technique:

Step one, chromaking (pre-treatment);

Step 2, on numerical-control full-automatic production line, the veined template of tool that computer is drawn is used to cover substrate surface, pressed powder is sprayed at substrate surface by the texture gap of crawler belt template, formation and template texture have the surface effect of identical patterns, then in the middle temperature of 100-150 degree, radiate gel through the Thermal Infra-Red of 13-20 minute to fix, the base material that surface powder texture gel is fixing is carried out 180-200 degree, the hot setting of 25-30 minute, texture is made to be attached to substrate surface firmly, after this step, substrate surface has veined place and is covered by powdery paints, do not have veined place still exposed, prepare for next step laser,

Step 3, on laser equipment, through metal principle of induction, the base material row laser ablation through step 2, and the place that covered by powdery paints is protected completely, exposed place, after laser ablation, is falling in inwards, makes substrate surface produce rough effect;

Step 4, surface shedding process, and after step 3, base material is being put into de-painting in acid pond and is soaking, making the region that substrate surface is covered by powdery paints exposed out;

Step 5, just through step 4 process after base material clear water be carried out, now base material tangent plane is all exposed, and face and tentatively had rough stricture of vagina reason;

Step 6, base material is carried out primary fluorine carbon basecoat paint by full-automatic spraying production line, temperature in 180-200 degree, last baking in 18-22 minute, make fluorine carbon priming paint uniform fold at substrate surface, and the concave-convex effect primary solidification according to texture, then carry out second time fluorine carbon finishing paint spraying again, through 200-220 degree high temperature, last baking in 20-25 minute, just fluorine carbon finishing paint coating fully covers substrate surface, and along with the Z-Correct bump mapping Z-correct of substrate surface forms the translucent protective layer of a sealing, superpower adhesive force; Spray followed by fluorocarbon varnish, through 200-220 degree high temperature, last baking in 20-25 minute, make product surface coating more tightly, effect more perfect; Product finally carrying out Lacquer finish process, uses the metal cap lac varnish even application of Gao Guang at product surface, then through 200-220 degree high temperature, last baking in 25-30 minute, allow high light texture fully demonstrate, make product surface gloss mellow and full, metal-like becomes apparent from.

So far, this technique completes, because product surface is coated with four bakings through four, and the texture on surface is etched in substrate surface through laser, the concave-convex effect making product surface texture and surface can occasionally forever embody, it is with weather-proof and famous fluorocarbon coating because of product surface spray coating again, the useful life making product extends further, so the product surface stereoeffect at explained hereafter place become apparent from, wear-resisting, true to nature, more can receiving space, the conversion of time, to reach prolonged, durable, economic, economical effect, it is worth promoting.

The embodiment of the above is only the preferred embodiments of the invention, not limits the practical range of the present invention with this, therefore all changes made according to the shape of the present invention, principle, all should be encompassed in protection scope of the present invention.
