Heat insulation energy-saving material and preparation method thereof

Abstract

The invention discloses a heat insulation energy-saving material. The heat insulation energy-saving material comprises the following components in parts by weight: 60-80 parts of cement, 30-40 parts of mineral cotton, 20-30 parts of sodium silicate, 10-30 parts of natural zeolite powder, 10-20 parts of coal ash, 5-15 parts of mullite fibers, 3-8 parts of floating beads, 5-10 parts of polyvinyl alcohol, 2-8 parts of carboxymethyl cellulose, 5-10 parts of a nano inorganic oxide, 8-15 parts of glass beads, 3-8 parts of glass fibers and 4-10 parts of an additive. The heat insulation energy-saving material is prepared by such processes as grinding dispersion, high-temperature mixing, standing cooling, sieving separation, pressing molding and high-temperature sintering. The heat insulation energy-saving material has the advantages of fire resistance, long service life, small heat conduction coefficient, environmental friendliness and the like, and meanwhile, has good acid and alkali corrosion resistance and ultrahigh weatherability.

Description

technical field [0001] The invention relates to the technical field of energy-saving materials, in particular to a thermal insulation and energy-saving material and a preparation method thereof. Background technique [0002] Energy conservation 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 the 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 con...

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, difficult to burn, 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
