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 its overall performance
[0004] Traditional thermal insulation materials only focus on thermal insulation performance, and seldom consider other characteristics such as fire resistance
However, most of the existing thermal insulation materials have poor fire performance, and their strength will decrease rapidly at high temperatures.

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.

Description

technical field [0001] The invention belongs to the technical field of building fire-proof and heat-preservation materials, and in particular relates to a fire-proof and heat-preservation composite material for buildings. Background technique [0002] The rapid development of the national economy has driven the continuous heating up of the building materials industry, and energy and the environment are [0003] Two issues that have attracted increasing attention in the industry have gradually been put forward based on new requirements for building energy conservation and environmental protection. However, the overall architectural design is unreasonable, the energy-saving effect is poor, and it is not coordinated with a series of safety protection measures such as the environment and fire protection, which seriously affects the overall performance of the building, making energy conservation and environmental protection useless, and thus affecting the entire construction indu...
