Problems solved by technology

[0004] However, with the progress of society, people's requirements for building materials are also constantly improving. Traditional hollow bricks only focus on weight and toughness, but little research has been done on their sound insulation effects. Therefore, the purpose of the present invention is to further improve the quality of finished hollow bricks. quality, enhanced sound insulation

Abstract

The invention discloses a sound-insulating hollow brick, which comprises the following raw materials in parts by weight: mineral wool fiber 5-8, slag 30-40, modified polyurethane foam material 6-9, bentonite 10-20, limestone 20-25 , straw powder 10-14, cellulose acetate 2-5, coal gangue 20-27, vermiculite powder 10-17, chitosan 2-4, fatty alcohol polyoxyethylene ether 1-2, the hollow brick of the present invention has very good Strength, and good sound insulation effect, high quality.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a sound-insulating hollow brick and a preparation method thereof. Background technique [0002] Coal gangue is one of the largest industrial solid wastes in China. Moreover, the annual discharge of coal gangue is equivalent to about 10% of the coal production in that year. The annual emission rate will be greater than 160 million tons. Stacking coal gangue not only takes up a lot of land, but also pollutes the environment and affects people's life and health. In addition, the spontaneous combustion of coal gangue can release a variety of harmful gases, etc., and at the same time it is accompanied by a large amount of smoke and dust and has the risk of explosion. Therefore, the spontaneous combustion of coal gangue has different degrees of impact on the surrounding atmospheric environment, human health, and animal and plant growth. Fly ash is one of the largest in...
