Embodiment Construction

[0021] Such as figure 1 As shown, the present invention is a hydrophobic perlite insulation board with a sandwich structure. There are 5 layers in total, which are multi-layer mesh cloth layer (2), hydrophobic expanded perlite layer (3), and single-layer mesh cloth layer ( 4), hydrophobic expanded perlite layer (3), multi-layer grid cloth layer (1).

[0022] In the above example, the multi-layer mesh cloth layer (1) contains 8 layers of mesh cloth, and the multi-layer mesh cloth layer (2) contains 3 layers of mesh cloth;

[0023] In the above example, the grid cloth is PET grid cloth or PA6 grid cloth or glass fiber grid cloth;

[0024] In the above example, the auxiliary material is PET staple fiber or PA6 staple fiber or glass fiber staple fiber with a length of 10-20mm;

[0025] The density of perlite in the above example is 100~400kg / m 2 , The thickness of hydrophobic expanded perlite layer is 20mm~50mm.

[0026] The implementation process of the present invention is: ...

Abstract

The invention provides a preparation technology of a novel sandwich insulation board. The preparation technology is characterized in that multilayer gridding cloth and inorganic lightweight aggregate form a sandwich structure, and a main structure is divided into five layers, which is shown as the attached figure. After expanded perlite is subjected to special hydrophobic processing, the expanded perlite is compounded with three layers of different gridding cloth, and the five-layer-structure sandwich insulation board is finally obtained. The preparation technology of the novel sandwich insulation board has the advantages that the technology is simple, the fireproof and insulating effects are good, and the insulation board can be widely applied to energy conservation and insulation of various buildings.

Description

technical field [0001] The present invention relates to a preparation process for a sandwich structure insulation board. The insulation board can be applied to the insulation of various building exterior walls, used as a heat insulation material, and also used as a pouring formwork. technical background [0002] With the rapid development of the global economy, the problem of energy shortage has gradually emerged, and energy conservation has become a research hotspot worldwide. As a developing country with high energy consumption, the heating energy consumption per unit building area in my country is about three times that of developed countries under similar climate conditions, and building energy consumption accounts for more than 25% of the total energy consumption in society. The issue of building energy conservation is directly related to the development of the national economy. sustainable development. [0003] Rock wool, expanded perlite, etc. are used as insulation m...
