Description

Method for improving viscosity of soundproof cotton
Technical Field
The invention belongs to the technical field of soundproof cotton materials, and particularly relates to a method for improving viscosity of soundproof cotton.
Background
Viscosity (Viscosity), also written as "Viscosity". Two blocks with the area of 1m2The plates of (2) are immersed in a liquid at a distance of 1m, and if a shear stress of 1N is applied so that the relative velocity between the plates is 1m/s, the viscosity of the liquid is 1 Pa.s. The flowing liquid is regarded as a plurality of liquid layers moving parallel to each other, and the velocities of the layers are different, so that a velocity gradient (dv/dx) is formed, which is the basic characteristic of the flow. The slower flowing liquid layer retards the flow of the faster liquid layer due to the velocity gradient, and therefore, the liquid creates a resistance to movement. In order to maintain a certain velocity gradient of the liquid layer, a counter force opposite to the resistance force must be applied to the liquid layer.
In today's society, noise pollution has become one of the major environmental pollution problems that are of worldwide concern following water pollution and air pollution. Sound-absorbing and sound-insulating materials are used for sound insulation and sound reduction, which are common means for treating noise pollution. The sound insulation cotton commonly used in the market at present comprises glass fiber sound insulation cotton, sponge, polyester fiber sound insulation cotton and the like. The glass fiber cotton is easy to cause skin itch and respiratory tract allergy, is harmful to human bodies and is not suitable for indoor use. Most of the sponge is a closed-cell foam material, has limited sound absorption performance and is more suitable for the field of heat preservation. The common polyester fiber soundproof cotton has narrow sound absorption bandwidth, only has good absorption for middle and high frequency sound, and has limited absorption effect for low frequency sound. The soundproof cotton used for the interior materials of automobiles or household electrical appliances not only needs good soundproof performance, but also needs to meet the requirements of safety, flame retardance, environmental protection, comfort, durability and the like.
On the one 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 insulation 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 demand of society for sound insulation materials is rapidly increased, and the traditional sound absorption materials can not meet the higher requirements of people on environmental protection, decoration, flame retardance, aging resistance and viscosity. Therefore, research and development of new environment-friendly sound-absorbing flame-retardant and anti-aging high-viscosity materials have been the direction of effort.
