Abstract
The invention relates to light absorption paint for laser quenching and a preparation method thereof. The invention is characterized in that the light absorption paint for laser quenching is prepared by evenly mixing the following components by weight or volume: 20-30g of SiO2, 2-4g of graphite powder, 8-12g of paint flake and 100-130mL of absolute alcohol. The preparation method comprises the following steps: (1) preparing 20-30g of SiO2, 2-4g of graphite powder, 8-12g of shellac and 100-130mL of absolute alcohol; (2) soaking 8-12g of paint flake in the absolute alcohol until the paint flake is completely dissolved; and (3) adding SiO2 and graphite powder into the absolute alcohol with dissolved paint flake, and evenly mixing. The light absorption paint can obviously increase absorbance and enable the energy density distribution to be more uniform. The invention obviously enhances the quenching hardness, avoids partial burnt phenomenon on the workpiece and increases the hardening layer thickness (up to 1.2-2.0mm). The invention has the advantages of reasonable formula, simple preparation, high safety, environmental protection, simple use and low cost.
Description
Technical field
The present invention relates to a kind of extinction coating and preparation method thereof, particularly a kind of laser quenching extinction coating and preparation method thereof.
Background technology
At present, because laser facula energy density distribution inequality, when laser quenching, laser directly scans workpiece, causes the phenomenon of hardness inequality, topical burn easily.Because it is lower that workpiece directly scans the laser energy absorption rate, laser quenching hardened layer is thinner, and 0.3-0.5mm only has an appointment.
Now there is the cost height in the extinction coating of widespread usage on the market, the shortcoming that light absorption ratio is low, and preparation has stricter requirement to production unit and environment, thus strengthen input and the production cost of implementing, when producing, also easily cause environmental pollution.
Therefore, provide a kind of prescription rationally, simple, the significant laser quenching of effect of preparation is with extinction coating and preparation method thereof, is one of these those skilled in the art problem that should address.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, provide the simple and tangible laser quenching of practical function of a kind of safety non-toxic, technology with extinction coating and preparation method thereof.
The technical solution adopted in the present invention is for achieving the above object: a kind of laser quenching extinction coating is characterized in that by weight or volumeter is mixed by following composition and is prepared from: SiO
2: 20-30g, Graphite Powder 99: 2-4g, coating agent which has to be dissolved in alcohol before use: 8-12g, raw spirit: 100-130ml.
A kind of laser quenching according to claim 1 preparation method of extinction coating is characterized in that implementation step is as follows:
(1) gets the raw materials ready: SiO
2: 20-30g, Graphite Powder 99: 2-4g, coating agent which has to be dissolved in alcohol before use: 8-12g, raw spirit: 100-130ml;
(2) with coating agent which has to be dissolved in alcohol before use: 8-12g is immersed in the raw spirit of described amount, dissolves fully until coating agent which has to be dissolved in alcohol before use;
(3) with SiO
2, Graphite Powder 99 adds in the raw spirit behind the dissolving coating agent which has to be dissolved in alcohol before use by described amount, stirring gets final product.
The invention has the beneficial effects as follows: adopt this novel extinction coating, can significantly increase light absorption ratio, make energy density distribution more even.Quenching hardness significantly improves, and avoids workpiece topical burn phenomenon, increases quench-hardened case thickness, can reach 1.2-2.0mm.
Do not pollute the environment in the production process of the present invention, do not need more equipment in addition, production technique is simple, easy to operate, the production environment condition is loose, need not the supporting facility that decontaminates, and uses storage safe reliable; And adopt raw material sources abundant and extensive, have significant use value and economic benefit.
In a word, the present invention fills a prescription rationally, prepares simple, safety and environmental protection, easy to use, with low cost.
