Abstract

The invention discloses a phosphate cement thermal insulation wall body material, which is characterized by comprising the following components in parts by weight: 100 parts of phosphate, 100-400 parts of metal oxide, 5-100 parts of solidification-regulating agent, 0.3-3 parts of foaming agent, 0.1-2 parts of foam stabilizer and 15-300 parts of water. The phosphate cement thermal insulation wall body material consists of metal oxide powder, phosphate, the solidification-regulating agent, pulverized fuel ash, ground slag, the foaming agent and the foam stabilizer; phosphate cement is taken as a substrate; and the cement has the characteristics of high early curing speed, high intensity, stable size, high corrosion resistance and the like. By adding the pulverized fuel ash and the ground slag, the construction cost of the thermal insulation wall body material can be lowered, cost can be saved, and the aims of utilizing waste and protecting the environment are fulfilled.

Description

[0001] technical field [0002] The invention relates to the technical field of building material engineering, in particular to a wall material, in particular to a phosphate cement thermal insulation wall material. [0003] technical background [0004] The development of wall materials is closely related to resources, energy, environment and building energy conservation. Clay solid bricks consume high energy, threaten land resources, and pollute the environment; lime-sand bricks have a high density and poor thermal insulation effect; concrete hollow blocks have large deformation and are prone to cracking. Air-entrained concrete has a high water absorption rate, which affects the thermal insulation performance of the wall. The construction of thermal insulation materials outside the wall is cumbersome, which increases the workload and poorly maintains the structural integrity of the building. Above-mentioned shortcoming has limited the application and popularization of ex...
