Problems solved by technology

Although the sound-absorbing panel has certain characteristics of moisture-proof, waterproof and sound-absorbing, but using hard polyvinyl chloride as the base material, the base material layer will gradually age and lose its effect as the use time prolongs, resulting in the sound-absorbing panel not being able to achieve the desired effect.

Abstract

The invention discloses a sound-absorption and waterproof attapulgite board and a preparation method, which belong to the technical field of attapulgite. The sound-absorption and waterproof attapulgite board comprises an abrasion-resistance and waterproof layer, a rubber buffer layer, a sound absorption layer, a board body and a waterproof protection layer in sequence from top to bottom, wherein the board body is prepared by taking attapulgite as a basic material; the sound absorption layer comprises an elastic layer and sound absorption fillers; a plurality of small holes are formed in the elastic layer and are filled with the sound absorption fillers; the sound absorption fillers are prepared by taking attapulgite as a basic material; the sound absorption layer is connected with the board body by adhesive; the sound absorption layer is connected with the rubber buffer layer by adhesive. The sound-absorption and waterproof attapulgite board has comparatively good sound-absorption, sound-insulation and waterproof effects and has the comparatively good characteristics of stable performance, high strength and good weather resistance; in addition, the preparation method has the characteristics of being simple and being convenient in operation and low in manufacturing cost, so that the current market requirement is met, and the application value is comparatively good.

Description

technical field [0001] The invention relates to the technical field of attapulgite, in particular to an attapulgite sound-absorbing waterproof board and a preparation method thereof. Background technique [0002] With the development of the times, people's living standards are improving day by day, and at the same time, the requirements for residences are also increasing accordingly, and people are gradually pursuing residences with good sound insulation effects. At present, most of the traditional construction companies use solid bricks. Solid bricks are dense inside and outside without holes. They are heavy and have poor sound insulation effect, so they are not easy to be used in high-altitude buildings. Therefore, in order to ensure a quiet and comfortable home environment, usually in the process of interior decoration, soundproof materials are used to rearrange the interior, which greatly takes up the indoor space and also increases the cost of home decoration. In addit...
