Abstract

The invention relates to a felt board with heat insulation and sound absorption. The felt board with heat insulation and sound absorption comprises a first fireproof fabric layer, a heat insulating and sound absorbing layer and a second fireproof fabric layer stacked in sequence from top to bottom. The heat insulating and sound absorbing layer comprises the following compositions of, by weight, 40-60 parts of copper ammonia fiber, 24-30 parts of aluminum silicate fiber, 15-20 parts of ethylene-vinylidene fluoride copolymers, 8-14 parts of polyethylene terephthalate fiber, 20-40 parts of wollastonite, 10-20 parts of sound absorbing agents and 6-12 parts of heat insulating agents. The felt board with heat insulation and sound absorption structurally comprises the first fireproof fabric layer, the heat insulating and sound absorbing layer and the second fireproof fabric layer, so that the felt board with heat insulation and sound absorption felt board has more excellent fireproof performance and heat insulation and sound absorbing properties, and the fire rating reaches the class A.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a felt board with heat insulation and sound absorption. Background technique [0002] With the development of economy and technology, people have higher and higher requirements for the indoor acoustics of buildings. For example, in hotel conference rooms and large sports venues, in order to achieve good acoustics, the interior decoration and decoration materials are put forward. A high sound absorption coefficient is required. With the development of science and technology, more and more materials and their composite components with both sound absorption and heat insulation and decoration functions are used for interior decoration and decoration. [0003] At present, the thermal insulation and sound absorption materials on the market mainly include mineral fiber products such as rock wool, glass wool, and aluminum silicate wool. polyethylene foam etc. These materia...
