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 10 to 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
The present invention relates to a kind of matrix material and sound proof member, relate in particular to a kind of flame-proof sound insulation matrix material and use the sound proof member of described flame-proof sound insulation matrix material.
Background technology
Along with the industrialization development of society, also seem more and more outstanding as the three big sound pollution problems of one of polluting.Noise can endanger people's auditory system, if for a long time under noise circumstance, can make the people tired, deaf, even jeopardize people's life.Simultaneously noise also can quicken to build, machine construction aging and damaging, influence the service precision of equipment and instrument and life-span etc.Therefore, the control of noise has become one of important topic that needs to be resolved hurrily now with control.
The control of noise should be taken into account the sound system of being made up of sound source, route of transmission and three links of recipient with control.Because first and the 3rd link belongs to outwardness, old friends mainly focus on and propagate control.At present, the method for Chang Yong control noise is sound absorption and sound insulation.So-called sound absorption promptly takes sound-absorbing material, sound absorption structure to reduce the reverberant sound that reflection causes, thereby reaches the purpose of control noise; Sound insulation promptly utilizes soundproof material or sound insulating structure to isolate or stop the propagation of acoustic energy, and noise and other environment are kept apart control and control to reach noise.Though the principle of the two is not quite similar, the former is for same environment, is by the internal friction that the loss of the VISCOUS FLOW of sound wave and intermolecular relative movement cause acoustic energy to be changed into heat energy dissipation to fall, and material mostly is porous loose structure; The latter then be another environmental facies for noise circumstance, material mostly is fine and close abundant structure.But sound insulation also comprises the sound absorption part, i.e. also help sound insulation in the time of sound absorption.
The defening effect of soundproof material characterizes with oise insulation factor.Theoretical analysis and experimental study show, partiting sound member for the individual layer homogeneous, its sound insulation property mainly is to change along with the area density harmony wave frequency difference of member, its defening effect is obeyed mass law: R=18 * lg ρ+12 * lgf-25, in the formula, R (dB) is the oise insulation factor under a certain frequency, ρ (kg/m
2) be the area density of material, f (Hz) is the incident sound wave frequency.From on can find out that the defening effect that improves material can realize by the mass area ratio that improves material.
About the existing lot of experiments in aspects such as sound-absorbing material and dependency structure thereof, and develop many widely used novel materials and new technology.Though and last for a long time about the development and the application of soundproof material, but all there are some either-or shortcomings in general soundproof material at present, such as the cost height, contain Toxic matter, mostly be that mechanically resistant material is difficult for secondary processing and the difficult sound insulation that is applied to irregularly shaped object is handled, thereby make its application limited.Find by literature search, China Patent No. is: 02157782.X, patent name is: hyperbaric sound insulation composite material, announced a kind of high-density sound insulation composite material, this patent the tungsten powder combination of PVC and diameter 2-60 micron, is made better, the nontoxic soundproof material of a kind of defening effect by coupling agent.Its material composition is tungsten powder and PVC and coupling agent, by injection moulding, compression molding, be used to do the soundproof material at city aerial conveyor traffic, aviation and harbour, and the sound insulation of building trade Light trabs interlayer processing, use this kind sound insulation composite material can reduce noise effectively.But this material is owing to adopted plumbiferous stablizer, and tungsten powder is on the high side, thereby has limited the use range of material.
