Problems solved by technology

[0006] However, in the above-mentioned three patents, the disclosed glass fibers for thermal insulation are all glass wool with a fiber diameter of 6-15 μm, and the glass fiber wool used has not been subjected to water-resistant modification treatment, resulting in the prepared glass wool for building thermal insulation Fiber cotton has defects such as low thermal resistance, poor bulkiness, low rebound rate under pressure, and failure of glass wool to absorb moisture.

Abstract

The invention relates to environment-friendly waterproof ultra-fine fibre glass cotton felt for building heat insulation and a preparation method of the environment-friendly waterproof ultra-fine fibre glass cotton felt, and belongs to the technical field of a functional composite. The cotton felt comprises the following components: 73-92wt% of ultra-fine fibre glass cotton, 2.5-4.55wt% of a processing agent and 5.5-22.5wt% of aluminum-foil coated fiberglass cloth, wherein the ultra-fine fibre glass cotton consists of the following components in percentage by mass: 82-93wt% of centrifugal cotton and 7-18wt% of flame cotton. The invention further relates to the preparation method of the ultra-fine fibre glass cotton felt. According to the method, the ultra-fine fibre glass cotton and the processing agent are compounded, and are uniformly distributed in the aluminum-foil coated fiberglass cloth, and through baking, the ultra-fine fibre glass cotton felt is manufactured. The ultra-fine fibre glass cotton felt also has the advantages of being high in thermal resistance value, high in fluffiness, high in depressing rebound degree, good in water resistance and the like, and can be widely used for heat insulation of building envelope structures.

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...
