Abstract

The invention discloses a preparation method of a high polymer material with high infrared light transmittance and belongs to the field of material modification. The method comprises the following steps: steps A: dissolving an MAH monomer, unsaturated silane containing carbon-carbon double bond and a peroxide initiator in an organic solvent to prepare a solution; step B: mixing PTFE resin powder with the monomer produced in the step A; step C: performing graft modification on the mixture obtained in the step B by melt grafting reaction equipment to obtain a PTFE-g-MAH modified polymer; and step D: preparing the high polymer material by modification of 100 parts of the modified polymer, 0.2-2 parts of toner, 1-5 parts of nano inorganic material and 1-5 parts of telluride metallic material.

Description

technical field [0001] The invention relates to the field of material modification, in particular to a polymer material with high infrared light transmittance. Background technique [0002] Infrared remote control is widely used in commonly used household appliances or electronic devices such as TVs, set-top boxes, and infrared 3D glasses. On these remote control devices, in order to receive infrared light, a hole is usually made on the appearance of the product, and the second is to make a hole on the appearance of the product to inlay a transparent product (remote control window). In this case, the appearance of the product is seriously affected and the difficulty and cost of product manufacturing are increased. Contents of the invention [0003] The object of the present invention is to: aim at the above-mentioned existing problems, provide a kind of macromolecule material with high infrared light transmittance, it is characterized in that, described macromolecular mat...
