Then, as shown in FIG. 8 , the laser processing apparatus 1 may produce a plurality of processed products Q through a laser.

And it further includes a coating device (not shown) for applying a coating solution for slowing rust generation on the surface of the classified workpiece (Q), and applies the coating solution to the sorted workpiece (Q) through the coating device (not shown).

Such a coating solution prevents the hydrophilic component from being absorbed or reacted into the body by the lipophilic component, thereby preventing rust of the processed product (Q).

Therefore, according to the embodiment of the present invention, a coating liquid was introduced to prevent rust on the surface of the processed product (Q).

In this case, the coating solution may be formed by applying a coating solution containing 30% by weight of bisphenol A phenoxy, 20% by weight of a photosensitive liquid epoxy, and 50% by weight of a functional additive. Bisphenol A phenoxy and a photosensitive liquid epoxy are used to form the adhesive.

Here, the bisphenol A-type phenoxy may be substituted with bisphenol F-type phenoxy, bromide-modified bisphenol A-type phenoxy, or bromide-modified bisphenol F-type phenoxy.

In addition, the photosensitive liquid epoxy may be substituted with a bisphenol A liquid epoxy, a bisphenol F liquid epoxy, a trifunctional or more polyfunctional liquid epoxy, a rubber-modified liquid epoxy, a urethane-modified liquid epoxy, or an acrylic-modified liquid epoxy.

The functional additive, which is a core component of the coating solution, effectively removes nitrogen oxides, organic halogen compounds, and odor gases present in the atmosphere, and prevents absorption or reaction of hydrophilic components into the body by lipophilic groups ( Q) can prevent rust formation.

Anatase titanium dioxide is stirred with a platinum chelate catalyst to produce titanium dioxide maintaining high hydrophilicity, and the produced titanium dioxide can make an active state not only in the ultraviolet region but also in the visible region, and electrons and holes in the active state It moves to the surface and combines with oxygen and hydroxyl groups to form radicals, so nitrogen oxides and organic halogen compounds can be removed.

And anatase titanium dioxide contains 12 parts by weight, and when used in less than 12 parts by weight, nitrogen oxides, organic halogen compounds, etc. cannot be effectively removed, and when used in excess of 12 parts by weight, to form a narrow energy band gap Hard.

Next, the platinum chelate is stirred with anatase titanium dioxide to produce titanium dioxide, and stirred with organosilane to produce an undecyl group in which an alkoxy alcohol and a polyether group are combined to have both hydrophilicity and lipophilicity. The platinum chelate contains 2 parts by weight, and when used in less than 2 parts by weight, the energy band interval of titanium dioxide cannot be effectively reduced, and when used in excess of 2 parts by weight, it is not economical.

Diallyl ester acetal is a curing agent, N-vinyl caprolactam is a hydrophilic monomer, and is stirred with a vinyl polysiloxane resin to have hydrophilicity.

Such diallyl ester acetal contains 4 parts by weight, and when used in less than 4 parts by weight, the curing rate is reduced, and when used in excess of 4 parts by weight, the optimum curing rate cannot be maintained, resulting in reduced economic efficiency and lowered physical properties can occur

In addition, N-vinyl caprolactam contains 10 parts by weight, and when used in less than 10 parts by weight or in excess of 10 parts by weight, hydrophilicity above a certain level cannot be secured.

The organosilane includes an undecyl group in which an alkoxy alcohol and a polyether group are bonded together using platinum chelate as a catalyst.

In this case, the undecyl group to which the alkoxy alcohol and the polyether group are bonded together includes a hydrophilic group and a lipophilic group.

Here, the organosilane contains 20 parts by weight, and when used in less than 20 parts by weight, the alkoxy alcohol and polyether groups do not bind to the undecyl group, and when used in excess of 20 parts by weight, it is not economical.

That is, the coating liquid is applied to the outer surface of the processed article (Q), the coating liquid contains a lipophilic component (L) on the surface of the processed article (Q), and a hydrophilic component (HL) on the upper end of the lipophilic component (L) By preventing the absorption or reaction of the hydrophilic component (HL) into the processed product (Q) by the lipophilic component (HL), including can do it

Various modifications and changes to the present invention described above with reference to the accompanying drawings are possible by those skilled in the art, and such modifications and changes not limited through the claims should be construed as being included in the scope of the present invention.
