Abstract

The invention discloses a molecule hybridization noise reduction material and its fabrication method, which comprises the following ingredients with different weight shares: base material of 15 to 30 weight shares; filler of 30 to 55 weight shares; biological contact agent of 1 to 3 weight shares; pigment of 0.01 to 0.05 weight shares; water of 5 to 15 weight shares. The preparation method of the material: mix the filler, contact agent and pigment to acquire filler mixture; mix and agitate the base material, a colloid, a crosslinking agent, a plasticizer, a stabilizer and water as 80 rounds/minute to acquire cementation material; agitate the mixture and the cementation material and then vibrate and filter them to get the material. The material, which has excellent light, heat and pH stability and prevents ageing; excellent noise reduction effect, can reduce the noise averagely by 10 to 50 dB in average; safe, which does no harm to human body; convenient for engineering.

Description

technical field [0001] The invention relates to a noise reduction material, in particular to a molecular hybrid noise reduction material and a preparation method. Background technique [0002] With the increase of urban building density, the increase of population congestion and the development of industrialization, noise is becoming one of the pollutants that affect human health. Noise levels exceeding 50 decibels will affect sleep and rest. Due to lack of rest, fatigue cannot be eliminated, and normal physiological functions will be affected to a certain extent; more than 70 decibels interfere with conversation, causing distraction, lack of concentration, affecting work efficiency, and even accidents; long-term work or living at noises above 90 decibels The environment can seriously affect hearing and lead to the occurrence of other diseases. In addition to damaging hearing, noise affects other systems as well. Nervous system manifests as neurasthenia symptoms mainly in...
