Abstract

The invention discloses a high-strength thermal-insulation wallboard for a building. The wallboard comprises an inner bearing plate, an outer bearing plate and a middle thermal-insulation core. The inner bearing plate and the outer bearing plate comprise the following components in parts by weight: 34-44 parts of cement, 27-37 parts of river sand with 30-70 meshes, 24-34 parts of natural-grading building sand with 50-160 meshes, 0.20-0.30 part of 19-mm polystyrene fibers, 0.05-0.11 part of redispersible latex powder and 0.08-0.15 part of a water reducing agent, and also comprises 3-8 parts byweight of additional lime putty. The wallboard disclosed by the invention is a bearing plate which is made by taking cement as a cementing material, and the strength is as high as 10 MPa. The wallboard can meet the requirements of secondary construction of all walls of the building, the surface is level and smooth, and surface treatment is not needed after installation.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength thermal insulation building wallboard. Background technique [0002] Among the wall materials in the construction market, there are many varieties of lightweight wall panels. Although these wallboards have integrated many modern technologies to varying degrees, in order to achieve the effect of large size, light weight and heat preservation. Due to excessive emphasis on the above effects, on the contrary, some basic properties that must be possessed as wall materials are ignored. The most prominent thing is that the surface strength of wall panels is generally low, generally between 3-5MPa, and some are even lower than 2MPa. Such wall surface strength and its adhesion are limited. And cause a lot of difficulties for building exterior wall surface insulation layer construction and decoration engineering construction, and greatly reduce the service life of exter...
