Abstract
The present invention discloses an ultraviolet ray absorption improving computer protection film which is characterized in that the computer protection film is prepared by adding modified tombarthite, pigment powder and crosslinking agent. The modified tombarthite is one or two of mixtures of lanthanum nitrate and yttrium nitrate. The computer protection film prepared by the method of the present invention has a high transparency, has significantly enhanced mechanical properties, and in particular has a strong absorption capacity for ultraviolet rays and can effectively prevent the damage of ultraviolet rays to eyes.
Description
Technical field
The present invention relates to a kind of computer protection film, be specifically related to a kind of computer protection film improving ultraviolet radiation absorption.
Background technology
The life of computer and modern has close relationship, a lot of people most of the time of one day facing to computer screen.The principle of work of computer can cause stored charge on computer screen, causes attract dust, with adverse consequencess such as surrounding objects electric discharges.Meanwhile, computer produces stronger ultraviolet, the microwave radiation light of low frequency, and when for a long time in the face of computer, eyes are easily tired, rubescent silk, and visual deterioration even has a strong impact on healthy, as dizziness, and headache, absent minded etc.
There is the radiation-resistant product much preventing computer radiate at present, as radiation proof computer protection film etc., but also effectively do not reduce the product of computer ultraviolet radiation.
Summary of the invention
The invention provides a kind of computer protection film improving ultraviolet radiation absorption.
Technical scheme of the present invention is as follows:
A kind of computer protection film improving ultraviolet radiation absorption; this computer protection film in PVC film raw material, adds modified RE, pigmented powder and linking agent be prepared from, and wherein said modified RE is one or both the mixture in lanthanum nitrate rare earth, Yttrium trinitrate rare earth.
In the present invention, the content of described modified RE is the 2-4% of PVC film raw material weight, and the content of described pigmented powder is the 0.0002-0.0004% of PVC film raw material weight, and the content of described linking agent is the 1-3% of PVC film raw material weight.
In the present invention, described PVC film raw material is prepared with the following method: be dissolved in by PVC in THF, adds photosensitizers and softening agent, and obtain the PVC solution that mass percentage is 5%, in described PVC solution, the content of photosensitizers is 1-3%, and the content of softening agent is 3-6%.
In the present invention, described pigmented powder is one or both the mixture in VK3 or T416.
In the present invention, the mass ratio of described VK3 and T416 is 1:1.
The present invention does not do special restriction to described linking agent, photosensitizers and softening agent, all can adopt at linking agent, photosensitizers and the softening agent that can realize this area of the present invention conventional.
Beneficial effect of the present invention: computer protection film transparency prepared by method of the present invention is high, mechanical property has
Remarkable enhancing, especially has very strong receptivity to ultraviolet, effectively prevents ultraviolet to the injury of eyes.
Embodiment
Following non-limiting example can make the present invention of those of ordinary skill in the art's comprehend, but does not limit the present invention in any way.Test method described in embodiment, if no special instructions, is ordinary method; Described reagent and material, if no special instructions, all can obtain from commercial channels, or can prepare in conventional manner.
