Light composite heat-preserving building blocks

Abstract

A light composite thermal insulated block is that a miniature hollow block of a light aggregate concrete and a polystyrene foam plate are integrated as a whole. The raw materials and the mixture ratio are that 15 to 16 percent of Portland cement, 69 to 71 percent of slag, 7 to 8 percent of sand, 0.3 to 0.5 percent of bubble bath, 0.7 to 1 percent of perlite, 3 to 4 percent of fibre, and 2 to 2.5 percent of polystyrene foam plate. The block is made by the steps that the materials are crashed and prepared; the water of 35 percent of the total weight of the raw materials is added to mixing uniformly; the mixture is poured into a mould and laid flatly as the thickness of 2 to 3 cm; a thermal reflection film is laid; the polystyrene foam plate is put into; the well mixed material is poured and laid flatly as the thickness of 2 cm; the polystyrene foam plate is put into; the thermal reflection film is laid again; the well mixed material is poured and plastered to be level with the mould; the material inside the mould and the mould are sent into a plastic film shed to keep the temperature; the mould is demounted after six hours; the material is covered by the plastic film to keep the temperature for three days; the material is watered and conserved for seven days; the material is piled as tallies and watered and conserved till 28 days; the material can leave factory after being inspected as eligible. The present invention reduces the working procedures of construction and reduces the cost of building and does not pollute the environment.

Description

technical field

[0001] The invention relates to the field of building wall materials, in particular to a lightweight composite thermal insulation block, and also relates to a process of the block. Background technique

[0002] Building a conservation-oriented society is the future development direction of all human beings. Facing the increasing depletion of resources and energy, conservation creates value. Therefore, the Ministry of Construction requires that the exterior walls of buildings must be treated with external insulation to reduce energy consumption, save resources, and reduce environmental pollution.

[0003] At present, the lightweight exterior wall materials used in the construction market are mainly aerated blocks, small hollow blocks of lightweight aggregate concrete, etc. The insulation material is mainly polystyrene foam board and so on. The main structure is to use the above-mentioned wall materials to build the outer wall, fix the polystyrene foam board ...
