Self-cleaning heat-insulating reflective material and preparation method thereof

Abstract

The invention provides a self-cleaning heat-insulation reflecting material. The self-cleaning heat-insulation reflecting material comprises an aerogel layer, a first aluminum foil layer, a first inflaming-retarding adhesive layer, an inflaming-retarding foam layer, a second inflaming-retarding adhesive layer, a second aluminum foil layer and a self-cleaning layer which are arranged in sequence. The self-cleaning layer is a modified teflon layer; the second inflaming-retarding adhesive layer comprises, by weight, 20-25 parts of polyurethane adhesive, 5-10 parts of curing agent, 40-50 parts of ethyl acetate, 20-30 parts of methyl alcohol, 5-10 parts of aminated graphene, 5-10 parts of nanometer silicon nitride and 10-15 parts of dopamine. The invention further provides a preparation method of the self-cleaning heat-insulation reflecting material. The self-cleaning layer with modified teflon being a main component is arranged and combined with the inflaming-retarding adhesive layers and the aerogel layer, and in this way, the reflecting material has the functions of low heat conduction, high inflaming retardance and self-cleaning, is suitable for building of breeding sheds, and reduces energy consumption and cleaning intensity.

Description

【Technical field】 [0001] The invention relates to the field of thermal insulation materials, in particular to a self-cleaning thermal insulation reflective material and a preparation method thereof. 【Background technique】 [0002] In recent years, under the call of promoting agriculture through science and technology, my country's modern aquaculture industry has developed rapidly. In the breeding industry, maintaining a suitable and constant temperature in the house is the first condition that must be met, and requires uniform temperature distribution, which is also the biggest problem that plagues the majority of farmers in our country. In order to meet the temperature requirements, coal is used in winter and physical cooling is used in summer, which consumes a lot of energy and the temperature is not uniform. At the same time, it also produces a lot of toxic gases such as CO and dust that are not fully burned, and the cleaning of the shed is labor-intensive. , greatly red...

In order to meet the temperature requirements, coal is used in winter and physical cooling is used in summer, which consumes a lot of energy and the temperature is not uniform. At the same time, it also produces a lot of toxic gases such as CO and dust that are not fully burned, and the cleaning of the shed is labor-intensive. , which greatly reduces the farming income
