Abstract

The invention discloses an external heat insulation system for an external wall with a rock wool belt composite heat insulation board. The external heat insulation system comprises a bonding layer, a heat insulation layer, a rendering layer, a facing layer and a fitting, wherein the bonding layer is prepared from the following raw materials in parts by weight: 350 to 400 parts of 42.5-grade cement, 600 to 650 parts of oven-dried river sand, 22 parts of dispersible latex powder, 4 parts of wood fiber, 1 to 3.5 parts of hydroxypropyl methyl cellulose and 0.1 to 3 parts of water reducing agent; the rendering layer is prepared from the following raw materials in parts by weight: 300 to 350 parts of 42.5-grade cement, 650 to 700 parts of oven-dried river sand, 28 parts of dispersible latex powder, 4 parts of wood fiber, 1 to 3.5 parts of hydroxypropyl methyl cellulose, 0.1 to 3 parts of water reducing agent and 3 to 5 parts of polypropylene staple fiber.

Description

technical field [0001] The invention relates to the technical field of external wall thermal insulation, in particular to an external thermal insulation system for an external wall of a rock wool belt composite thermal insulation board. Background technique [0002] The energy consumption per unit area of ​​my country's buildings is 3-5 times that of developed countries. With the vigorous promotion and use of residential buildings, the use of wall panels for interior wall decoration and insulation has been widely promoted and recognized. But at the same time, the problem of fire protection of wall panels is also in front of us. In recent years, fires have occurred in building interior wall panels in China, causing serious casualties and property losses. Building flammable and combustible internal insulation materials have become a class New fire hazards, therefore, the upgrading of the fire performance of the wall panels used in building interior walls has become an urgent p...
