Abstract

The invention provides a sound absorption and insulation sheet material and a preparation method thereof. The sound absorption and insulation sheet material is composed of, by weight, 50 to 80 parts of cement, 20 to 30 parts of pottery sand, 30 to 40 parts of waste haycite, 6 to 10 parts of silica sol, 5 to 8 parts of starch, 3 to 5 parts of a water repellent, 1 to 8 parts of carbon fiber, 1 to 3 parts of a foaming agent, and 7 to 15 parts of water. The preparation method is simple; operation is convenient; rive sand can be replaced with pottery sand; broken stone can be replaced with waste haycite; a large amount of solid waste in urban garbage can be used; the preparation method is beneficial for changing wastes into valuables, realizing resource cyclic utilization, reducing mineral mining and consumption, and protecting the environment; and the obtained sound absorption and insulation sheet material is high in noise reduction coefficient, and possesses excellent thermal insulation properties.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a sound-absorbing and sound-insulating board and a preparation method thereof. Background technique [0002] In modern society, indoor pollution has seriously threatened human health. With the improvement of people's living standards and living tastes, people pay more and more attention to the environment optimization and purification of public places, living spaces, daily life and medical facilities. With the advancement of science and technology and the continuous change and development of mainstream social values, the requirements for building panels are getting higher and higher, which urgently requires ceramic manufacturers to speed up the pace of new product development and continuously introduce new products to meet the different needs of consumers. Thermal insulation and sound insulation panels are a common building material in modern buildings, an...
