Accurate composite heat-insulation building block

Abstract

The invention provides an accurate composite heat-insulation building block. The accurate composite heat-insulation building block comprises a surface layer material and a filling material and has a multilayered structure; the surface layer material which is in the shape of a sheet is arranged on the outer layer of the building block; the filling material is foamed by nitrogen; and the surface layer material wraps the filling material. The accurate composite heat-insulation building block is a silicate product; the service life of the accurate composite heat-insulation building block is the same with that of a building; a heat conductivity coefficient is low, desiccated bulk weight is light, and self heat insulation of a wall body can be implemented; and the accurate composite heat-insulation building block is simple in structure, facilitates construction, and is accurate in self external dimension, high in structure, stable in physical performance indexes and long in service life; secondary plastering is not required; and the accurate composite heat-insulation building block gives a way for reform and development of a wall material.

Description

technical field [0001] The invention relates to the field of building energy conservation, in particular to a precision composite thermal insulation block. Background technique [0002] The country vigorously advocates green and energy-saving buildings, and uses filling materials with high apparent strength, good flatness, precise dimensions, and self-insulation functions. It can save a lot of resources, reduce labor costs, reduce energy consumption, and effectively reduce environmental pollution. [0003] At present, all kinds of block and wall board filling materials have not fundamentally solved the problems of energy saving of the outer protective wall of the building and the need for secondary plastering of the inner partition wall of the building. Moreover, some products have complex structures and difficult construction, which has caused problems such as increased costs and high quality hidden dangers in the later stage. Contents of the invention [0004] Based on...
