Abstract

The invention discloses a heat insulation and heat preservation composite film with an air purifying function and a preparation method of the heat insulation and heat preservation composite film. The heat insulation and heat preservation composite film comprises an inorganic fiber gridding cloth layer, a heat insulation and heat preservation composite layer, an adhesive layer and an air purification composite layer, wherein the inorganic fiber gridding cloth layer comprises glass fiber gridding cloth or basalt fiber gridding cloth or ceramic fiber gridding cloth or carbon fiber gridding cloth; the heat insulation and heat preservation composite layer comprises a plastic layer and a metal oxide coating; and the air purification composite layer comprises a microporous polytetrafluoroethylene film, a charcoal layer and a plastic layer film. The heat insulation and heat preservation composite film has an efficient air purification function, is capable of durably eliminating harmful substances such as benzene and formaldehyde in air, plays a role in protecting the health of a human body, has a molecule controlled release function, and has a series of advantages of controlling release speed and space concentration, prolonging service life, being simple in manufacture process, saving the production cost, playing roles of saving energy and reducing emission, and the like.

Description

technical field [0001] The invention relates to a thermal insulation membrane material and a preparation method thereof, in particular to a thermal insulation composite membrane with air purification function and a preparation method thereof. Background technique [0002] In recent years, excessive energy consumption has led to environmental pollution, and environmental pollution has led to a decline in air quality. Human living environment and health are being threatened more and more than ever before. It is imminent to provide a healthy living environment for human beings with the simultaneous development of energy saving and consumption reduction and air purification. In this context, the use of new molecular slow-release thermal insulation film materials with air purification function has become imminent. However, the above-mentioned membrane materials have not been successfully developed in China at present. In order to solve the above problems, this patent, on the ba...
