Problems solved by technology

The problem is that the thermal conductivity is 1.60-2.00w / m.k lower than that of ordinary concrete walls, which is 0.8W / m.k-1W / m.k lower than the existing technology, which is far from meeting the needs.
Solving the problem of poor thermal insulation performance has become an urgent need

Abstract

A novel efficient energy-saving fireproof thermal insulation concrete and a preparation method thereof. The thermal insulation concrete is composed of cement, redispersible latex powder, composite fiber, methyl cellulose ether, glazed hollow bead and an air entraining agent. The concrete has the characteristics of fire resistance, water resistance, thermal insulation resistance, severe cold resistance and light weight, and is suitable for all base materials of walls and insulation of various complex shapes of walls, and is all closed, seamless, cavity-free and free of hot and cold bridge. The concrete has coefficient of thermal conductivity in the range of 0.05 W / m.k-0.06 W / m.k, saves the energy consumption of buildings, and is applicable to all types of buildings. The concrete not only can be applied to external thermal insulation of external wall as well as interior thermal insulation of external wall, or external and interior thermal insulation of external wall, roof heat insulation and geothermal insulation layer. The concrete not only can replace traditional mixed plastering mortar but also can substitute on-site composite wall insulation construction of complex paste warming plate, due to its good heat insulation and energy saving effect. The invention has the advantages of simple construction operation, easy quality control and high construction efficiency, and is convenient for large-scale popularization and application.

Description

Technical field: [0001] The invention relates to fire-proof and heat-preserving concrete for buildings and a preparation method thereof, in particular to a formula and a preparation method of a novel high-efficiency and energy-saving fire-proof and heat-retaining concrete material suitable for various wall base materials and various complex-shaped walls. Background technique: [0002] At present, polystyrene styrene panels (EPS) and extruded polystyrene panels (XPS) for thermal insulation of buildings are superior in thermal insulation performance, but their safety performance is not high. Because they are not resistant to high temperature and flammable, As a result, fire accidents occur frequently, but because there is no special fireproof insulation material to replace it, it has become a major problem in the building insulation industry. In order to solve this problem, people have made various efforts. For example, people have invented some thermal insulation mortar p...
