Description

Gray powder lining soundproof cotton and preparation method thereof
Technical Field
The invention relates to the technical field of soundproof cotton manufacturing, in particular to ash-based liner soundproof cotton and a preparation method thereof.
Background
Noise pollution is a big public hazard of human living environment, which not only seriously damages the auditory nerve, cardiovascular system and nervous system of people, but also accelerates the aging of buildings and industrial machinery, and influences the precision and service life of instruments. With the increasing emphasis on the noise control problem, various sound insulation and noise reduction methods are also brought forward. The traditional sound insulation material, glass wool, has many defects, such as low noise reduction coefficient, short service life, environmental pollution, secondary pollution, etc., and the application of the glass wool is limited, so that the glass wool is out of the market and is replaced by a novel sound absorption material. The fiber sound-absorbing material can have a good sound-insulating effect in a wide frequency band, so that the fiber sound-absorbing material can replace the traditional porous partition material represented by centrifugal glass wool and the like, and the sound-insulating material which has the advantages of environmental protection, reutilization, decoration function and excellent acoustic performance can be more and more accepted by the market.
On the other hand, with the increasing requirements on life practicality and fire safety, people have higher and higher flame retardant requirements on soundproof cotton. At present, the flame retardant technology enters a new development stage, and the flame retardant technology of the sound-absorbing material is developing towards the direction of high efficiency, economy and environmental protection in the future. Since the inorganic flame retardant has: low toxicity and good thermal stability; does not precipitate and has lasting flame retardant effect; no corrosive gas is generated; the price is low; the inorganic flame retardant has the advantages of small smoke generation amount and the like, so the application of the inorganic flame retardant in various aspects is gradually replacing the organic flame retardant, and the research significance of synthesizing the inorganic flame retardant is great; however, since organic flame retardants are still being used in large amounts at present, the use of inorganic flame retardants in combination with organic flame retardants is a desirable transition.
At present, the social demand for sound insulation materials is rapidly increased, and the traditional sound insulation materials cannot meet the higher requirements of people on environmental protection, decoration and flame retardance; in addition, the tensile strength of the general soundproof cotton is not good, and the soundproof cotton is easy to break or form cracks during the stretching process, thereby affecting the use of the soundproof cotton. Therefore, research and development of new environment-friendly soundproof and flame-retardant materials with high tensile strength have been the direction of effort.
