Problems solved by technology

However, the phenolic foam sold in the market in the prior art also has problems such as long construction period and complicated construction procedures when applied to the insulation of walls and roofs.
Chinese patent CN2789018Y, published on June 21, 2006, discloses a honeycomb core reinforced phenolic foam. The material is filled with a phenolic foam in the honeycomb core. Although the material is light in weight and good in strength, its impact resistance Not ideal, the cost is better, and the production is more complicated

Abstract

The invention discloses a three-dimensional sandwich textile material filled by phenolic aldehyde foams. The textile material is characterized by comprising an upper textile surface, a middle sandwich structure, and a lower textile surface; the middle sandwich structure takes a three-dimensional sandwich textile material as a support body, and takes phenolic aldehyde foams as a filling substrate; the middle sandwich is connected with the upper textile surface and the lower textile surface; the upper textile surface is a plane structure; and the lower textile surface is a polygons structure. Compared with the prior art, the three-dimensional sandwich textile material filled by phenolic aldehyde foams has the advantages of heat preservation, sound insulation, pressure resistance, high strength and good fireproof performance.

Description

technical field [0001] The invention relates to a three-dimensional sandwich fabric material, in particular to a three-dimensional sandwich fabric material filled with phenolic foam. Background technique [0002] The traditional honeycomb sandwich composite material has the characteristics of light weight, heat insulation, and sound insulation. However, due to its poor flat tension and double-layer shear performance, the material is easy to delaminate and has poor impact resistance, which affects its application range. [0003] Phenolic foam has obvious characteristics of flame retardancy, low toxicity, low temperature and high temperature resistance. Due to the unique porous structure and a certain proportion of open structure, the product has waterproof and breathable functions. The wall can maintain water and gas balance in various climates. Prevent wall volume water mildew and blackening and other phenomena. At the same time, the special material structure of phenolic f...
