Abstract
Description
technical field
[0001] The invention belongs to the technical field of functional composite materials, and in particular relates to an environment-friendly water-resistant superfine glass fiber felt for building heat preservation and a preparation method thereof. Background technique
[0002] In order to save energy and protect the environment, the demand for thermal insulation of the building envelope will continue to increase. However, neither the traditional red brick nor the rapidly developing new wall materials can meet the energy-saving requirements of the envelope. Glass fiber cotton is a kind of loose fiber material, and its bulk density changes greatly. Because when the thermal conductivity increases correspondingly and the bulk density is small to a certain extent, air circulation convection heat transfer will occur in the material, while the loose glass fiber There is an optimal bulk density with the smallest thermal conductivity. In recent years, glass fiber, as...
