High strength external wall heat insulation board and preparation technology thereof

Abstract

The invention discloses a high strength external wall heat insulation board and a preparation technology thereof. The high strength external wall heat insulation board is characterized by comprising the following raw materials by weight: 22-32 parts of portland slag cement, 16-26 parts of quicklime, 14-20 parts of quartz sand, 22-28 parts of hydrogen peroxide, 10-20 parts of steel slag, 14-20 parts of sawdust, 22-28 parts of expansive clay, 10-20 parts of fly ash, 12-20 parts of dolomite powder, 12-20 parts of paraffin powder, 12-22 parts of dihydrogen phosphate, 12-18 parts of cement powder,12-18 parts of water glass, 10-16 parts of calcium oxide, 9-16 parts of foam polyurethane, 6-12 parts of aerogel, 6-12 parts of phenol formaldehyde resin, and 15-25 parts of foam concrete. According to the high strength external wall heat insulation board and the preparation technology thereof, steel slag, sawdust, dolomite powder and other assistants are added on the basis of portland slag cement, expansive clay, foam concrete and the like, the high strength external wall heat insulation board has the characteristics of high strength, good heat insulation effect and light weight, can bear high pressure, also has simple preparation process, is low in product cost, and can be applied and promoted on a large scale.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a high-strength external wall thermal insulation board and a preparation process thereof. Background technique [0002] With the continuous advancement of urbanization, high-rise buildings are being built in many places, and the outer surfaces of many buildings need a large number of insulation boards. Most of the insulation boards on the market have mediocre strength. After several years of use, there are risks such as cracking and falling off. In recent years, high-altitude insulation boards have frequently fallen, which poses a problem for the strength and other mechanical properties of the insulation board. higher requirement. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a high-strength external wall insulation board and its preparation process, the insulation board is made of slag Port...
