Inverted-type roofing heat-insulation light plate and preparation method thereof

Abstract

The invention relates to an inverted-type roofing heat-insulation light plate which is in a double-layer composite structure comprising a mixed mortar surface layer and a light granule material bottomlayer through pouring formation, wherein the material of the mixed mortar surface layer is prepared from cement, fly ash, rough sand, additives and water, and the material forming the light granule bottom layer is prepared from cementing agent, granule material, water reducing agent, foaming agent, waterproof agent and water. The cement agent is prepared from fly ash, cement, calcium carbide ash,salt plaster and excitant. The granule material is polystyrene foaming material. The heat-insulation light plate has good heat insulation, waterproof, anti-leakage and weathering resistance, long service life and no protection layer on the surface, simplifies the construction technology, uses the industrial waste material, and has energy saving, environment protection, low volume weight of the heat-insulation plate and good strength.

Description

technical field [0001] The invention relates to a thermal insulation board of a house, in particular to an inverted roof thermal insulation lightweight board and a preparation method thereof. Background technique [0002] The building roof is an important part of the building envelope, and its energy consumption accounts for about 10% of the building as a whole. Due to the cold winter and hot summer, the invasion of wind and rain, and the weathering of the sun, the selection and construction of roof insulation, waterproof, and weatherproof materials are more and more valued by the industry. The current technical scheme of roof construction is basically that on the concrete hollow slab (or cast-in-place concrete) on the roof of the building, there are: cement mortar leveling layer, air barrier layer, thermal insulation layer, slope layer, leveling layer, waterproof layer, waterproof protective layer , reinforcement layer, etc. In the inverted roof structure, the waterproof ...

AI Technical Summary

Problems solved by technology

As far as the inverted roofing material products appearing at present, most of them are cast-in-place insulation layers, and the construction process is still relatively complicated.

At present, although there are some cases where heat insulation boards are used, due to rain erosion and weathering, the insulation boards used are easily damaged, and it is necessary to make another protective layer on the insulation board, which not only increases the construction cost, but also complicates the construction. Not easy to repair
