Manufacturing method and product of anti-fingerprint plastic parts

Abstract

The invention discloses a manufacturing method of a fingerprint-resisting plastic part and a product of the manufacturing method. The manufacturing method comprises following steps: firstly, a plastic part material is molded through injection; secondly, the plastic part is material is sprayed through adoption of an ultrasonic gradual layer, and according to spraying of the gradual layer, the plastic part material is sequentially subject to spraying heads with different spraying coatings; and thirdly, the coatings are cured. According to the manufacturing method, through adoption of the ultrasonic gradual layer spraying method, the fingerprint-resisting layer on the surface of the manufactured product is a nano thin layer, attaching performance is good, and the production cost is low.

Description

[0001] 【Technical field】 [0002] The invention relates to a method for making a plastic part and its product, and in particular to a method for making an anti-fingerprint plastic part and its product. [0003] 【Background technique】 [0004] As people increasingly pursue high-quality life, consumers have higher and higher requirements for 3C products. In addition to having more and stronger functions, they also pay more and more attention to their shape and appearance decoration effect. Therefore, the shell of 3C products Higher requirements are put forward, such as hoping for high light, no bonding lines, etc. However, high-gloss products are prone to fingerprints, which is against the wishes of consumers. [0005] At present, the methods for making fingerprints on the product surface easy to wipe are mainly applied in the application and development of touch screens (such as glass, acrylic or their composite materials, etc.), and the application area is relatively narrow. ...

However, high-gloss products are easy to stick fingerprints, which is against the wishes of consumers

[0005] At present, the methods to make the fingerprints on the surface of the product easy to wipe are mainly used in the application and development of touch screens (such as glass, acrylic or their composite materials, etc.), and the application area is relatively narrow.

[0006] In the prior art, in order to better suppress fingerprints, sweat, dirt, etc. generated by finger touch when using the touch screen, the usual treatment method is to vacuum sputter (PVD) a layer of inorganic silicon film on the touch screen panel to reduce the surface tension to achieve hydrophobicity. The purpose of anti-fouling, but the investment in PVD coating equipment is expensive

In addition, another treatment method is to form a thin film coating of oxysilane compound additives or fluorine-based compound additives and attach it to the substrate. However, this wet coating is easy to implement, but the pollution effect is limited. and short life

[0007] In the Chinese patent whose publication number is CN103540183A, it is mentioned that the UV coating method containing 0.1-0.9 μm particles is coated on the touch screen, or the method of using atmospheric plasma activation treatment on the glass touch screen and then spraying a thin layer of anti-fingerprint agent to achieve However, the products processed by the above-mentioned glass-like process have disadvantages such as poor adhesion between the anti-fingerprint layer and the material, and easy peeling off.

[0008] In the Chinese patent whose publication number is CN103073934A, it is mentioned that the UV-curable anti-fingerprint coating for the mirror substrate of acrylic (PMMA, commonly known as plexiglass) substrate or acrylic / polycarbonate composite substrate (PMMC / PC), but Applies only to touch screen products

[0009] In Japanese Patent JP0716940, a kind of anti-pollution paint is also disclosed, but it needs to be coated twice to increase the production cost

In addition, currently known anti-fingerprint coatings all adopt conventional coating methods (such as slit coating, knife coating, flow coating, dimple coating, dip coating, roller coating or spray coating, etc.), and the film thickness is relatively thick. It is impossible to realize micro-nano spray coating, which will affect the texture and anti-fouling effect. Although an anti-fingerprint coating is mentioned in US20120251706A1, the film thickness can reach 20-50nm, but the specific implementation of the coating method is not mentioned.

[0010] In view of this, it is necessary to provide a method of making anti-fingerprint plastic parts and its products to solve the problems of easy peeling off of the above-mentioned anti-fingerprint layer, relatively thick film layer and high cost.
