High-strength heat insulation wall plate and production technique thereof

Abstract

The invention discloses a high-strength heat insulation wall plate which comprises an inner and an outer bearing plates as well as a middle heat insulation core, wherein the inner and the outer bearing plates respectively comprise components in parts by weight: 34-44 cement, 27-37 river sand of 30-70 meshes, 24-34 natural-grade building sand of 50-160 meshes, 0.20-0.30 19mm polypropylene fiber, 0.06-0.16 12mm polypropylene fiber, 0.05-0.11 dispersible latex powder, 0.08-0.15 water reducing agent and 3-8 additionally added lime paste. The wall plate is a bearing plate manufactured by taking the cement as a cementing material, has the strength reaching up to 10MPa, meets the requirement of secondary construction of all wall bodies of buildings, has flat and smooth surface, and does not need surface treatment after being installed.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-strength thermal insulation wallboard and its production process. 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 ser...
