Problems solved by technology

However, the protective screen materials of existing touch screens are mainly glass products. One is that the glass protective screen is easily broken when squeezed, and it is very sharp after being broken, which is very easy to cause human injury. The other is that it does not have the function of anti-electromagnetic radiation. The glass protective screen is harmful to the health of the human body

Abstract

The invention discloses an electromagnetic radiation-proof transparent material for a touch screen and a preparation method of the electromagnetic radiation-proof transparent material. The electromagnetic radiation-proof transparent material is prepared from the following raw materials in parts by weight: 15 to 20 parts of dichloromethane, 9 to 12 parts of tetrahydrofuran, 12 to 16 parts of cyclohexene oxide, 0.18 to 0.25 part of boron trifluoride diethyl etherate, 0.05 to 0.12 part of ethylene glycol, 60 to 70 parts of isophorone diisocyanate, 0.15 to 0.20 part of dibutyltin dilaurate, 35 to40 parts of methacrylic acid-beta-hydroxyethyl ester, 0.7 to 1.0 part of azobisisobutyronitrile, 1 to 2 parts of carbon nanotubes, 10 to 20 parts of iron nitrate and 3 to 4 parts of polyvinyl alcoholaqueous solution. By adopting the transparent material prepared by the preparation method, under the combined effect of the carbon nanotube and the iron oxide, the reflective loss and the absorptive loss can be simultaneously performed on the electromagnetic radiation, the transfer of surface energy can be obstructed, so that the electromagnetic radiation energy is converted to heat energy, the electromagnetic radiation energy is reduced, and the harm to the physical and psychological health of the human being can be reduced.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to an electromagnetic radiation-proof transparent material used for a touch screen and a preparation method thereof.
