Fire-retardant heat-insulation material

Abstract

The invention discloses a fire-resisting heat-insualting material. Its composition comprises 1.5-2.0 portions of component A and 0.8-1.2 portions of component B, said component A contains (wt%) low-calcium flyash 55-62%, calcium hydroxide 15-22%, kaolin 15-22%, glass fibre 0.6-0.9% and magnesium hdyroxid3 4-7%. Said product possesses excellent fire-resisting and heat-insulating properties, and is a new building material.

Description

technical field [0001] The invention relates to a building material, in particular to an exterior wall building material, in particular to a thermal insulation wall material. Background technique [0002] With the continuous development of science and technology, people have put forward higher requirements for building materials, but the building materials currently used for exterior walls are not ideal in their various properties, especially in terms of energy saving, fire prevention, and heat preservation. According to the needs of the department, most exterior wall building materials use black cement as the binder, which has a large specificity, generally about 2.7, high thermal conductivity, poor bonding performance, easy to fall off, and difficult construction operation. Contents of the invention [0003] The technical problem to be solved in the present invention is to disclose a fire-proof and heat-insulating material to overcome the above-mentioned defects in the p...
