Energy-saving material with thermal insulation function

Abstract

The invention discloses an energy-saving material with a thermal insulation function. The energy-saving material comprises raw materials as follows: aerogel, coal ash, isocyanate, decabromodiphenyl ethane, sulfonated acetone formaldehyde, a liquid epoxy resin dispersing agent, polyurethane, rice hulls, a coupling agent, mullite fibers, ceramic microbeads, bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate, 2-hydroxy-4-methoxybenzophenone and an ultraviolet light absorber. According to the energy-saving material, the thermal insulation performance is good, the dry density of a product is 160-200 kg / m<3>, the heat conductivity coefficient is 0.02-0.03 W / (m*K), and the product has good thermal insulation and energy saving effects; the fireproof performance is good, the fire endurance is longer than 3 h and can meet the level-A fire protection standard, and accordingly, good fire resistance is achieved; the sound insulation performance is good, and noise influence can be greatly reduced; the endurance is good, and the material has the characteristics of high-temperature and low-temperature resistance, corrosion resistance, ultraviolet irradiation resistance and good weather fastness.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thermal insulation and energy-saving material Background technique [0002] Energy saving and environmental protection have become a major issue that human beings must face in the 21st century, and it has also become an important issue that our construction industry must focus on solving. Improving the thermal insulation performance of houses is an important measure for building energy saving and consumption reduction. Under the advocacy of the state, many new buildings and many old buildings are applying thermal insulation layers on the outer walls and inner walls to reduce energy consumption. To achieve the effect of heat insulation in the house, that is, to prevent heat radiation from being transmitted to the house through the heat insulation material of the inner and outer walls in hot summer, and reduce the energy consumption of household appliances such as air ...

Problems solved by technology

Among them, the main advantages of organic material boards are low density, high heat preservation efficiency, and good toughness. The disadvantages are poor fire resistance, easy to ignite after fire, and will produce toxic smoke during the combustion process, which seriously endangers life safety, and also has aging resistance. Defects such as poor performance, short service life, complicated installation procedures, and high cost

The advantages of inorganic material thermal insulation layer are: low cost, flame retardant, no smoke generated during fire, good aging resistance, same lifespan as the building, easy installation, low cost, etc. The disadvantage is that it will increase the overall cost of the building. Weight, material lack of toughness
