Problems solved by technology

At present, the wall insulation materials are mainly polystyrene and polyurethane foam materials. The thermal conductivity of this material reaches 0.04w / m.k, and the thermal insulation performance is poor, especially in terms of fire resistance. Combustible materials that emit a large amount of toxic gases after burning have caused many vicious fires in recent years. Therefore, this material is hardly used in energy-saving and thermal insulation buildings in developed countries such as Europe and the United States.

Abstract

The invention discloses an external wall heat-insulation and fire-retardant material and a preparation method thereof. The external wall heat-insulation and fire-retardant material is characterized by being prepared from 60-70 parts of foamable thermoset phenolic resin, 30-40 parts of thermoset linear urea resin, 3-8 parts of Tween 80, 10-30 parts of quartz powder, 10-15 parts of micro powder aluminium hydroxide, 10-20 parts of 4A zeolite, 5-12 parts of n-pentane and 2-6 parts of concentrated sulfuric acid. The external wall heat-insulation and fire-retardant material product disclosed by the invention is characterized in that the oxygen index is more than or equal to 55%, the water absorption is less than or equal to 2% (soaked for 24 hours), the heat conductivity coefficient is 0.02-0.029w / mk, the stability and weather resistance of the product are good, and the external wall heat-insulation and fire-retardant material product is non-toxic, odourless and environmentally-friendly. The external wall heat-insulation and fire-retardant material product is ideal fireproof, heat-insulation, energy-saving and beautiful environmentally-friendly decorative material. Detections carried out by national fireproof construction material quality supervision and inspection center show that the combustion performance of the external wall heat-insulation and fire-retardant material product disclosed by the invention is up to the grade A of the standard GB8624-2006 classification for burning behaviour of building materials and products.

Description

technical field [0001] The invention relates to a thermal insulation and flame retardant material, in particular to an external wall thermal insulation and flame retardant material and a preparation method thereof. Background technique [0002] Since my country put forward the development concepts of "sustainable development", "saving renewable resources", and "building a harmonious society", environmental protection, energy saving and emission reduction, and weather safety have been truly implemented. The State Environmental Protection Administration and the Ministry of Housing and Urban-Rural Development implement mandatory thermal insulation for residential, office, and commercial buildings. At present, the wall insulation materials are mainly polystyrene and polyurethane foam materials. The thermal conductivity of this material reaches 0.04w / m.k, and the thermal insulation performance is poor, especially in terms of fire resistance. Materials that are combustible and em...
