Abstract

The invention discloses a method for coating and hardening the surface of an HDPE plastic optical product, which comprises the following specific steps: A. carrying out static electricity removal treatment on the surface of the HDPE product; B. SiO is put into a film coating machine2A material; C. putting the processed HDPE product into a film coating machine; D. vacuumizing the coating machine until the set vacuum degree is reached; E. start of SiO Evaporation2So that the film is uniformly attached to the surface of the HDPE product, and the evaporation is stopped after the film reaches the set film thickness, and the film coating is finished. Has the advantages that: the invention plates a layer of SiO on the surface of HDPE plastic product2The hard coating layer is added, so that the original HDPE plastic product with the softer surface and the hardness of 2-grade Mohs hardness is changed into harder HDPE plastic product, the coated film reaches 6-grade Mohs hardness, the hardness of the coated film is effectively improved, and the scratch resistance is improved.

Description

Method for coating and hardening surface of HDPE plastic optical product
Technical Field
The invention discloses a method for coating and hardening the surface of an HDPE plastic optical product, belonging to the technical field of coating of HDPE plastic optical products.

In order to achieve the purpose, the invention provides the following technical scheme: the method for coating and hardening the surface of the HDPE plastic optical product comprises the following specific steps:
A. carrying out static electricity removal treatment on the surface of the HDPE product;
B. SiO is put into a film coating machine2A material;
C. putting the processed HDPE product into a film coating machine;
D. vacuumizing the coating machine until the set vacuum degree is reached;
E. start of SiO Evaporation2So that the film is uniformly attached to the surface of the HDPE product, and the evaporation is stopped after the film reaches the set film thickness, and the film coating is finished.
Preferably, SiO in step B2The material adopts high-purity silicon dioxide microspheres.
Preferably, the vacuum degree set in the step D is 3*10-3Pa。
Preferably, the thickness of the film layer set in the step E is 400-600 nm.
Compared with the prior art, the invention has the following beneficial effects:
the invention plates a layer of SiO on the surface of HDPE plastic product2The hard coating layer is added, so that the original HDPE plastic product with the softer surface and the hardness of 2-grade Mohs hardness is changed into harder HDPE plastic product, the coated film reaches 6-grade Mohs hardness, the hardness of the coated film is effectively improved, and the scratch resistance is improved.
