Problems solved by technology

For example, the widely used air-entrained concrete structure has unique physical, chemical, and mechanical properties. Although it has many advantages as building roof insulation and external wall insulation materials, the biggest disadvantage of air-entrained concrete is that it is easy to produce cracks, thereby affecting i

Abstract

The invention relates to the technical fields of research and production of fireproof and thermal-insulation materials for buildings and discloses a fireproof and thermal-insulation composite for a building. After being modified, basalt fibers can be uniformly distributed on a macromolecular chain of high-density polyethylene, so that the fireproofness and the flame retardance are improved; and ifthe fireproof and thermal-insulation composite is mixed into cement, the crack resistance of a cement structure can be effectively improved, and other performances of a thermal-insulation material cannot be basically changed while the fireproof grade is increased. The fireproof and thermal-insulation composite provided by the invention is capable of coordinating thermal insulation and fireproofness and resisting to 500 DEG C high temperature and small in heat conductivity coefficient smaller than 0.02W/m.K and also has the overall performances such as stable size, wear resistance, chemical corrosion resistance, moth resistance and corrosion resistance.
