Abstract
The invention discloses a composite heat-insulating heat-preserving material. The heat-preserving material is prepared from a solid feedstock and a thickening and water retention agent, wherein the solid feedstock is prepared from the ingredients in parts by weight: 28 parts of staple lead silicate fibers, 12 parts of staple basalt fibers, 4 parts of basalt fiber powder, 6 parts of floating beads, 13 parts of perlite powder, 9 parts of sodium oxide and 20 parts of cement 425#. The composite heat-insulating heat-preserving material disclosed by the invention is excellent in heat-insulating heat-preserving performance, is non-toxic, odorless, pollution-free and non-irritating and has class-A incombustible fireproof performance; and during construction, the composite heat-insulating heat-preserving material can be prepared into paste through being added with water and then is directly smeared to the surface of a building, so that the construction is simple and easy.
Description
technical field [0001] The invention relates to a thermal insulation material, in particular to a thermal insulation material which can be used for inner and outer walls of buildings, roofs, thermal insulation pipes and thermal equipment. Background technique [0002] With the rapid development of the domestic economy, the living standards of Chinese people are also rising steadily. A very prominent performance is the vigorous development of the domestic construction industry. More and more people have moved from low-rise bungalows to high-rise buildings. In order to live comfortably and save energy, the outer walls of high-rise buildings are usually equipped with thermal insulation materials. Although there are many kinds of insulation materials commonly used at present, they generally have defects such as poor fire protection rating, difficult construction, poor bonding ability, easy detachment, and poor wind pressure resistance and impact resistance. Therefore, it is of ...
