Description

Has lining part of anti-fingerprint coating and preparation method thereof
Technical field
The present invention relates to a kind of lining part and preparation method thereof with anti-fingerprint coating.
Background technology
Along with the use of 3C electronic product is more and more frequent, the human consumer has also had increasingly high requirement to the outward appearance of product.Except requiring attractive in appearance, the hand feel and drape of product casing color, also require its surface to have wear resistance, scratch resistance and anti-fingerprint (anti-fingerprint) performance preferably.
The more anti-fingerprint method of industry use at present is at base material spraying one deck organic chemicals, like anti-fingerprint coating or anti-fingerprint wet goods, makes it bright in luster attached to forming on the base material through heating or drying, the organic coating with certain anti-fingerprint effect.But this preparation technology of coating is very loaded down with trivial details, but also exists free formaldehyde etc. to be unfavorable for the chemical substance of environmental protection and HUMAN HEALTH.In addition, above-mentioned organic coating wear resisting property is relatively poor, easy abrasion after use for some time.
Summary of the invention
In view of this, be necessary to provide a kind of environmental protection, attrition resistant lining part with anti-fingerprint coating.
A kind of lining part with anti-fingerprint coating comprises base material and is formed at the anti-fingerprint coating on this base material, and this anti-fingerprint coating comprises a transparent SiO 2A layer and a transparent CaF 2Layer, this SiO 2Layer is positioned at this base material and this CaF 2Between the layer.
A kind of preparation method with lining part of anti-fingerprint coating comprises the steps:
Base material is provided;
On this base material, deposit an anti-fingerprint coating through vacuum coating method, this anti-fingerprint coating comprises a transparent SiO 2A layer and a transparent CaF 2Layer, this SiO 2Layer is positioned at this base material and this CaF 2Between the layer.
Compared to prior art, the anti-fingerprint coating of deposition on the above-mentioned employing vacuum coating method base material, this anti-fingerprint coating comprises SiO 2Layer and CaF 2Layer is because this CaF 2Contain the existence of fluorine in the layer, thus its surface tension less (less than the surface tension of water), thus make water at this CaF 2Laminar surface is difficult to sprawl, and has hydrophobic preferably, anti-fingerprint effect.And, CaF 2Layer and SiO 2Layer is transparent, can not influence the appearance of other decoration coatings between base material and the anti-fingerprint coating.On the other hand, because anti-fingerprint coating has higher hardness, stable performance does not contain Toxic matter, makes that lining part wear resisting property is better, environmentally friendly.

Embodiment
See also Fig. 1, the lining part 10 that preferred embodiment of the present invention has anti-fingerprint coating comprises base material 12 and is formed at the anti-fingerprint coating 14 on this base material 12.
Said base material 12 can be processed by metallic substance or non-metallic material.This metallic substance can comprise stainless steel, titanium, titanium alloy, copper, copper alloy, aluminium, duraluminum and magnesiumalloy etc.These non-metallic material can comprise plastics, pottery, glass etc.
This anti-fingerprint coating 14 comprises a transparent SiO 2Layer 141 and one transparent CaF 2Layer 143.This SiO 2Layer 141 is positioned at base material 12 and CaF 2Between the layer 143.SiO 2141 on layer connects transitional function, is used to increase CaF 2The bonding force of layer 143 and base material 12.SiO 2The thickness of layer 141 is approximately 0.02~0.05 micron.CaF 2Layer 143 is formed at this SiO 2On the layer 141, CaF 2The thickness of layer 143 is approximately 0.1~0.5 micron, and preferred thickness is 0.1~0.3 micron.
A surface-coated CaF of above-mentioned lining part 10 2 Layer 143, this CaF 2In the layer 143 because the existence of fluorine, so its surface tension less (less than the surface tension of water), thereby make water at CaF 2Layer 143 surface are difficult to sprawl, and have hydrophobic preferably, anti-fingerprint effect.
This covering member 10 can be housing, furniture, kitchen utensils or other decoration part of 3C electronic product.
The preparation method of above-mentioned lining part 10 mainly comprises the steps:
At first, base material 12 is provided, and this base material 12 is carried out the plated film pre-treatment.This pre-treatment mainly comprises: base material 12 is put into the ultrasonic cleaner that is loaded with ethanol and/or acetone soln shake cleaning, with the impurity of removing base material 12 surface and greasy dirt etc.
Plasma clean is carried out on surface to the base material after above-mentioned cleaning 12, and further cleaned base material 12 surfaces are to improve base material 12 surfaces and follow-up coating's adhesion.Concrete operations and processing parameter that this plasma cleans are: base material 12 is put into the Vakuumkammer of a vacuum coating film equipment, and being evacuated to vacuum tightness is 2 * 10 -3~8.0 * 10 -3Pa, feeding high-purity argon gas is ion source gas, opens the ion source power supply, and plasma bombardment is carried out on base material 12 surfaces, bombardment time is 3~10min.
Base material 12 through above-mentioned pre-treatment is carried out vacuum plating handle, to form this anti-fingerprint coating 14 on base material 12 surfaces.The concrete film coating method that forms this anti-fingerprint coating 14 can adopt a kind of in rf magnetron sputtering and the vapor deposition.
Present embodiment adopts this anti-fingerprint coating 14 of rf magnetron sputtering plating, and concrete operations and processing parameter are following: after base material 12 is carried out plasma clean, open SiO 2The target power supply; Power is 100~400W; Control base material 12 temperature are at 20~200 ℃, and feeding flow to Vakuumkammer is that the argon gas of 100~200sccm is a sputter gas, and to feed flow be that the oxygen of 10~30sccm is as reactant gases; To replenish the Sauerstoffatom that lacks in the sputter deposition process, beginning plating SiO 2 Layer 141, the plated film time was controlled at 6~15 minutes.Then, close SiO 2Target and oxygen are opened CaF 2Target power supply, power is 100~400W, argon flow amount remains unchanged, and opens deposition CaF 2Layer 143, depositing time is approximately 10~20 minutes.Close CaF 2Target power supply stops to feed argon gas, treat 14 coolings of said anti-fingerprint coating after, bubbling air in Vakuumkammer is opened door for vacuum chamber, takes out the base material 12 that plating has anti-fingerprint coating 14.
Understandable, deposition should be anti-fingerprint coating 14 before also can be on base material 12 plating one color layers 13.Correspondingly, this lining part 10 can also comprise a color layers 13 between base material 12 and anti-fingerprint coating 14, to strengthen the aesthetic property of this lining part 10.
Said preparation method with lining part 10 of anti-fingerprint coating adopts the vacuum coating method SiO transparent prior to deposition on the base material 12 one 2 Layer 141 is as connecting transition layer, again in this SiO 2Layer 141 deposition one CaF 2Layer 143.Because this CaF 2Contain the existence of fluorine in the layer 143, thus its surface tension less (less than the surface tension of water), thus make water at CaF 2Layer 143 surface are difficult to sprawl, and have hydrophobic preferably, anti-fingerprint effect.And, CaF 2Layer 143 and SiO 2 Layer 141 is transparent, can not influence the appearance of other decoration coatings between base material 12 and the anti-fingerprint coating 14.On the other hand, because anti-fingerprint coating 14 has higher hardness, stable performance does not contain Toxic matter, makes that lining part 10 wear resisting propertys are better, environmentally friendly.
