Problems solved by technology

[0003] At present, sound-absorbing materials commonly used in the construction field, such as asbestos, glass wool, rock and mineral wool, etc., although these materials have certain sound-absorbing properties, their sound-insulating properties are poor, and the above-mentioned materials are harmful to the human body, especially during construction operations. , more harmful to the human body and the surrounding environment
Although imported materials have good sound absorption and sound insulation properties, the cost is too high
In addition, in indoor swimming pools, indoor skating rinks,...

Abstract

The invention discloses a construction material with the effects of sound absorption, sound insulation, heat preservation, anti-condensation, etc., a preparation method and the application thereof. The construction material consists of the following independent constituents: constituent I, constituent II and constituent III; wherein, the constituent I is a water-base interfacial agent; the constituent II mainly consists of the following constituents according to certain weight portion: 55 to 65 portions of plant fiber and 35 to 45 portions of caking agent; the constituent III is a sealing agent. The construction material of the invention is made of wood fiber by chemical treatment and the construction material is sprayed on the base surface of buildings, which has the effects of sound absorption, sound insulation, heat preservation and anti-condensation, fire protection, moulding prevention, etc. The construction material of the invention is completely suitable for being used on a base surface configuration of any building, such as arc form, waveform, etc., and also is suitable on large-scale public places needing sound absorption, sound insulation, heat preservation, anti-condensation, fire protection, etc. such as a gymnasium, a natatorium, an opera house, a cinema, an exhibition center, an airport, tunnel, an industrial factory building, a machinery room, etc.

Description

technical field [0001] The invention relates to a building material, in particular to a building material with functions of sound absorption, sound insulation, heat preservation, anti-condensation, etc. The invention also relates to a preparation method and application of the building material, belonging to the field of building materials. Background technique [0002] At present, noise has become a major environmental pollution, and the acoustic environment of buildings has attracted more and more attention. It is one of the most commonly used and most basic technical measures in building noise control engineering to select appropriate materials for sound absorption and sound insulation treatment of buildings. The interior surfaces of buildings include floors, walls and ceilings. Traditional decorative materials are stone, panels and plaster. Due to the physical properties of these materials, sound waves are strongly reflected. If you have a meeting, listen to a report o...
