A new type of three-dimensional sandwich flame retardant composite insulation board

Abstract

The invention discloses a novel three-dimensional sandwich flame-retardant composite heat-retaining board. A fabric material comprises an upper fabric face, a middle core material structure and a lower fabric face, wherein a three-dimensional sandwich fabric material is used as a support body of the middle core material structure, a lightweight aggregate is used as a filling matrix, and the middle core material structure connects the upper fabric face with the lower fabric face; the upper fabric face is a plane structure; and the lower fabric face is a geometric plane structure. Under the premise of meeting the waterproofing and strength use requirements, the combustion performance of the material achieves non-combustible grade A. The material has the advantages of light weight, high strength, excellent fireproof, heat-retaining and heat-insulating properties, corrosion resistance, good sound insulation, noise reduction functions, and the like and has broad application prospects in the fields of buildings, traffic transportation, petrochemical industry, aerospace, ships and energy sources.

Description

technical field [0001] The invention relates to a three-dimensional sandwich fabric material, in particular to a novel three-dimensional sandwich flame-retardant composite thermal insulation board, which belongs to the field of building materials. Background technique [0002] With the global energy shortage and the implementation of the mandatory energy-saving standards of the Ministry of Construction, more and more attention has been paid to energy-saving building walls, and external insulation of building walls has gradually become the development direction. However, the existing external thermal insulation wall is directly used as a decorative surface outside the thermal insulation layer, and most of the thermal insulation materials used are organic thermal insulation materials or thermal insulation materials with relatively high organic content. Under the action of a strong heat flow, it will also burn and melt, and at the same time produce a large amount of toxic smoke...

AI Technical Summary

Problems solved by technology

However, as a traditional thermal insulation method, the energy-saving effect is not good, prompting people to look for a more effective combination with lightweight aggregates to improve the thermal insulation performance of these products

The traditional masonry mortar and plastering mortar have defects in use, such as heavy weight, poor thermal insulation performance, and cracks after use.
