Abstract

The invention relates to the technical field of plastic, and in particular relates to infrared reflection / emission thermal-insulating plastic functional master batch and a preparation method thereof. The master batch comprises the following components in percentage by weight: 5-40% of pre-dispersed infrared reflection nano material, 5-50% of infrared emission pigment packing, 5-20% of hollow micros beads, 0.1-5% of surface treating agent, 20-48.9% of synthetic resin and 1-10% of additive. Infrared reflection / emission thermal-insulating plastic made of the master batch can replace infrared reflection thermal-insulating coatings in multiple fields, and not only is the time and labor waste in spraying coatings avoided, but also environment pollution caused by organic solvent volatilization is avoided.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to an infrared reflection / emission thermal insulation plastic functional masterbatch and a preparation method thereof. Background technique [0002] The light and heat that the sun gives to the earth enable all things to grow and continue. As a kind of energy, solar energy has been fully recognized by human beings and continuously utilized. The sun benefits the earth, nature and mankind. But just like everything has positive and negative effects, excessive solar heat has also brought many troubles to the earth, nature and human beings, and even caused disasters. In modern society, with the continuous warming of the earth, excessive solar heat radiation has dried up rivers and lakes and desertified land, endangering the survival of human beings; the strong urban heat island effect has made people endure unbearable high temperatures. Human beings have overcome the troubles brought...
