The absorbent is coated on the surface of a ceramic in a technological process for cutting the ceramic by the aid of the fiber laser. The absorbent is characterized in that an oily material and acetone are proportioned to manufacture the absorbent, and colorants, colorant assistants, stabilizers, resists, wetting agents and preservatives are proportioned to manufacture the oily material. The absorbent has the advantages that a light absorption effect of the ceramic is excellent after the absorbent is used for the ceramic, a phenomenon of light interruption is prevented, the ceramic can be cut by the aid of the laser at one step, the absorbent is environment-friendly, can be easily coated on the surface of the ceramic and is easy to clean, the ceramic can be cleaned in alcohol after being cut, intrinsic characteristics of the ceramic cannot be changed, corrosion is prevented, the appearance of the ceramic is identical to that of a ceramic which is not coated with the absorbent, and the like.
Description
Technical field
The present invention relates to optical-fiber laser cutting ceramic field, relate in particular to a kind of absorbent for optical-fiber laser cutting pottery.
Background technology
Laser cutting parameter is that the energy that discharges when adopting laser beam to shine ceramic surface makes pottery fusing and evaporation, pass through focus set, make laser beam concentrate on very little zone, energy height is concentrated cutting part is carried out rapid local heat, make the material evaporation, along with light beam moves relative to linear with material, make hole form the joint-cutting of narrower in width continuously, side cut is influenced by heat very little, and laser beam does not apply any power to material, be untouchable processing, so it is little or not have an advantage of being out of shape that the pottery of Laser Processing has distortion, in current laser cutting ceramic industry, what great majority adopted is traditional carbon dioxide laser cutting ceramic technology, lasing light emitter generally adopts the carbon dioxide high-power laser beam, because its cutting speed and smooth substantially cutting section efficiently at present also are the main flow technology that pottery divides plate processing.
Yet the carbon dioxide laser cutting has for the ceramic cutting processing of some requirements at the higher level
Following shortcoming: cost is higher, efficient is low, the cut edge is uneven, for example the straight cuts of circuit unit profile just can't be suitable for, concavo-convex with as the ceramic substrate marginal existence stamp edge of carbon dioxide high power laser light cutting, the fluctuating scope is bigger, for the while efficiently at assurance laser cutting ceramic substrate, reduce similar stamp edge, someone has proposed to use optical-fiber laser to cut the method for pottery, but because the problem of ceramic material behavior own, absorption efficiency to laser is not high enough, disconnected optical phenomenon can appear, can't disposable cutting pottery, and efficient is not high enough.
Summary of the invention
Technical problem solved by the invention is: at the existing fiber laser cutting technique exist disconnected optical phenomenon cause can't disposable cutting pottery problem, provide a kind of new absorbent to be coated in ceramic surface, assurance improves cutting efficiency to the absorption of ceramic surface to laser.
The technical solution used in the present invention is, a kind of absorbent for optical-fiber laser cutting pottery, in the technological process of optical-fiber laser cutting pottery, absorbent is coated in ceramic surface, described absorbent is formed by oily material and acetone proportioning, and described oily material is formed by pigment, pigment auxiliary agent, stabilizing agent, resist, wetting agent and anticorrisive agent proportioning.
As further optimization of the present invention, the volume ratio of described oily material and acetone be 1:500 to 1:550, stirring after the dilution gets final product.
As further optimization of the present invention, described pigment adopts ferric tannate and gallic acid iron, described pigment auxiliary agent adopts dark blue dyestuff, described stabilizing agent adopts oxalic acid solution, described resist adopts the resin type cure polymer, described wetting agent adopts glycerine, and described anticorrisive agent adopts the penta sodium pentachlorophenate medicament.
As further optimization of the present invention, the mass percent that described pigment accounts for oily material is 10% to 30%, the mass percent that the pigment auxiliary agent accounts for oily material is 10% to 30%, the mass percent of stabilizer comprises oily material is 10% to 30%, the mass percent that resist accounts for oily material is 10% to 30%, the mass percent that wetting agent accounts for oily material is 10% to 30%, and the mass percent that anticorrisive agent accounts for oily material is 10% to 30%, and being added in stirs in the container can obtain oily material.
The invention has the beneficial effects as follows, use the extinction effect of pottery behind this absorbent fine, disconnected optical phenomenon no longer appears, the laser cutting pottery can disposablely be finished, and this absorbent itself also has advantages such as environmental protection, easy Tu, easy cleaning, and pottery can be placed directly in and clean in the alcohol after cutting is finished, and can not change the characteristic of pottery itself, also corrosion phenomenon can not take place, outward appearance is the same with the pottery that is not coated with absorbent.
