Abstract

The invention provides a manufacturing method for a modified damping material. The technical problems that no corresponding manufacturing method exists for an existing damping material, the damping material needs to be manufactured based on experience, and manufacturing is complex are solved. The manufacturing method for the modified damping materials includes the following steps that a, 16 weightparts of cotton fibers, 6 weight parts of glass fibers, 11 weight parts of aluminum fibers, 9 weight parts of gypsum powder, 7 weight parts of asbestos powder, 5 weight parts of wood fibers, 3 weightparts of nanocarbon, 4 weight parts of magnesium oxide and 1 weight part of anti-aging agent are weighed; b, the raw materials are poured into a stirring machine to prepare a mixture; c, the mixtureis subjected to hot pressing to form a strip-shaped board, wherein the thickness of the strip-shaped board is 80 mm; d, the surface of the strip-shaped board is sprayed with protective liquid throughspraying equipment, and the strip-shaped board is dried through a drying system; e, the strip-shaped board is punched into a needed shape, and then the damping material is obtained. The manufacturingmethod has the advantage of providing convenience in manufacturing.

Description

technical field [0001] The invention relates to a method for making an improved sound-absorbing material. Background technique [0002] Almost all the owners who live in the building have this kind of trouble. The various sounds from the neighbors are very disturbing, especially when falling asleep at night, it is easy to be woken up by the sudden sound, and it is difficult to fall back asleep after waking up. , This kind of voice is especially reflected in the days when there are major competitions like the European Cup. It is really not easy to interfere with others. You must let them stay in your own home. In fact, the solution is very simple, that is, to use professional sound-absorbing materials to achieve. Most of the sound-absorbing materials are loose and porous materials, such as slag wool, blankets, etc. The sound-absorbing mechanism is that the sound waves penetrate into the pores of the material, and the pores are mostly open holes that communicate with each oth...
