preparation example Construction

[0041] A method for preparing a thermal insulation board in an embodiment includes the following steps S110-S160:

[0042] S110 , laying surface layer raw materials to form a first surface layer.

[0043] Among them, the surface layer raw materials include glass fiber cotton and airgel.

[0044] It can be understood that glass fiber wool is an inorganic non-metallic material with excellent performance. It has a wide variety and has good insulation, heat resistance, corrosion resistance and mechanical strength. Airgel is a form of solid matter with extremely low density. Since more than 80% of airgel is air, it has a very good heat insulation effect. One inch thick airgel is equivalent to 20 to 30 pieces of ordinary glass. Thermal insulation function. Therefore, using glass fiber wool and aerogel as surface layer raw materials can take advantage of the loose structure of glass fiber wool to adsorb airgel in the pores of glass fiber wool, greatly improving the toughness and st...

Embodiment 1

[0068] (1) Pretreatment of construction waste: take out the steel bars in the construction waste, sort and crush the construction waste after drying, sieve with a 0.4mm sieve hole, and take the under-sieve as the production raw material for subsequent use;

[0069] (2) Pretreatment of glass fiber cotton: dry glass fiber cotton, remove harmful substances and impurities, and set aside;

[0070] (3) Preparation of surface layer raw materials: mix the pretreated glass fiber cotton and airgel evenly for standby; mix the desiccant, bactericide and mildewproof agent evenly for standby;

[0071] (4) Preparation of raw materials for the middle layer: mix the foamed plastic particles and the pretreated construction waste in a ratio of 1:2, and set aside;

[0072] (5) Lay the mixture of glass fiber cotton and airgel obtained in step (3) evenly in the die, and the thickness is determined according to the thickness of the wall or roof hollow layer of the prefabricated building with thin-wa...

Abstract

The invention relates to a heat preservation and insulation board, a preparation method thereof and an application of the board. The heat preservation and insulation board comprises a middle layer andsurface layers arranged on two opposite sides of the middle layer, the middle layer is prepared from foamed plastics and building rubbishes, and the surface layers are prepared from glass fiber cotton and aerogel. The heat preservation and insulation board has good heat preservation, heat insulation and sound insulation effects, uniform heat preservation and insulation effects and good strength and toughness, is not easy to age and applicable to thin-walled steel assembly buildings and has the advantage of light weight.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a thermal insulation board, its preparation method and application. Background technique [0002] Prefabricated buildings refer to buildings assembled on site using prefabricated components, including prefabricated concrete buildings, thin-walled light steel structure prefabricated buildings, modern wood structure buildings and other buildings that meet the characteristics of prefabricated buildings, with standardized design, factory Six characteristics of production, assembly construction, integrated decoration, information management, and intelligent application. The development of prefabricated buildings is conducive to saving resources and energy consumption, reducing construction pollution, improving labor production efficiency and quality and safety levels, and is conducive to promoting the deep integration of the construction industry and information industrialization. ...
