Abstract

The invention relates to a flame-retardant sound insulation composite material. The flame-retardant sound insulation composite material comprises the following components in percentage by weight: 5 to 30 percent of PVC, 5 to 30 percent of chlorinated polyethylene, 15 to 80 percent of iron powder of which the grain diameter is 10 to 100 microns, 0.5 to 2 percent of coupling agent and 9.5 to 23 percent of aid. The invention provides the flame-retardant sound insulation composite material, which is prepared from the PVC, the chlorinated polyethylene, the iron powder with the grain diameter of 10to 100 microns, the coupling agent and the aid, has good flame-retardant sound insulation effect, and also has the characteristics of flame retardancy, innocuity, no lead, high strength, good construction property and low cost. Because the chlorinated polyethylene is particularly introduced into the material components of the flame-retardant sound insulation composite material, the using amount of a plasticizer of the material is reduced, and the composite material has better softness and can be widely applied to sound insulation treatment in the construction industry, decoration field and the like; and the sound insulation composite material can effectively reduce the noise, and the sound insulation index of the material can reach 25 to 32 decibels.

Description

technical field [0001] The invention relates to a composite material and a sound-insulating component, in particular to a flame-retardant and sound-insulating composite material and a sound-insulating component using the flame-retardant and sound-insulating composite material. Background technique [0002] With the development of social industrialization, the problem of noise pollution, one of the three major pollutions, is becoming more and more prominent. Noise can harm people's auditory system. If people are in a noisy environment for a long time, it will make people tired, deaf, and even endanger their lives. At the same time, noise will also accelerate the aging and damage of buildings and machine structures, and affect the accuracy and lifespan of equipment and instruments. Therefore, the prevention and control of noise has become one of the important issues to be solved urgently. [0003] The prevention and control of noise should take into account the acoustic syst...
