Abstract
The purpose of a composite sound insulation material disclosed by the invention is achieved as follows: according to the composite sound insulation material, a vinyl chloride-vinyl acetate resin material with an excellent sound insulation effect is prepared by virtue of the following steps: mixing and stirring raw materials in a predetermined proportion, performing first mixing polymerization and second mixing at normal temperature to ensure that the materials are mixed more uniformly, performing second rolling and mixing to prepare plates and cutting boards with proper sizes and shapes by virtue of calendering, and the like. The composite sound insulation material is characterized by being prepared by uniformly mixing the following components in percentage by weight: 10-75% of vinyl chloride-vinyl acetate resin, 10-20% of methyl vinyl silicone rubber, 2-7% of low density polyethylene, 10-55% of precipitated barium sulfate and 1-10% of superfine fibers. The vinyl chloride-vinyl acetate resin sound insulation material disclosed by the invention has the significant characteristics that noises with relatively low frequency can be insulated; and when the sound insulation material is in use (for example, the material is used as the sound insulation material for vehicles), conventional filling materials or cotton can be matched, and noises with relatively high frequency (such as the noises generated by a vehicle power system or a vehicle body) can be insulated, so that a good sound insulation effect can be achieved.
Description
Technical field
The present invention is a kind of composite sound isolating material, refers in particular to a kind of vinyl chloride-vinyl acetate resin sound-proof material.
Background technology
Current China's economic is fast-developing, and every field there occurs fundamental change, comprehensive vertical strive in line with international standards.In construction industry too, in recent years in waterproof, the problem of the aspects such as indoor pollution obviously increased, and wherein topped the list for lodging a complaint of noise, and noise pollution has caused ubiquitous puzzlement to the life of people.The requirement prevented for noise can be more and more higher, and increasing individual and mechanism, from changing in idea, start living environment and the Working environment of wishing to improve oneself, thirst for liberating from life noise and public noise.Based on such situation, nation-building committee member is also in the management improved and strengthen noise gradually and requirement, to new building acts be had to come out in the near future, when the time comes national standard is had to the requirement of noise, this is the inexorable trend of Chinese development, is also that the one that China steps into globalization social is now levied.The best means abated the noise is exactly the sound-proof material adopting high efficiency low cost, and will have free from environmental pollution, the characteristic do not contained hazardous substance.Most export dependence of China, the effect of domestic like product does not reach international standard at all.So the invention provides a kind of novel vinyl chloride-vinyl acetate resin sound-proof material.
Summary of the invention
The present inventor, for the shortcoming of traditional sound insulating sheet material, studies sample through design search in many ways, provides a kind of novel vinyl chloride-vinyl acetate resin sound-proof material.
Main purpose of the present invention is to provide provides a kind of vinyl chloride-vinyl acetate resin sound-proof material.By changing its raw material composition and proportioning, the better and material of the molecule associativity between each material being evenly distributed, by it, there is the noise blocking lower frequency, reach the object of preferably soundproof effect.
The object of the present invention is achieved like this: a kind of composite sound isolating material, it is by the raw material mix and blend of predetermined proportion, pass through first time mixing polymerization at normal temperatures, the mixing material mixing that makes of second time is more even, carry out that secondary roll-in is mixing rolls the sheet material appropriate size and shape, cut out the steps such as plate, make the good vinyl chloride-vinyl acetate resin material of sound insulation, it is characterized in that: be made up of the component of following weight per-cent: vinyl chloride-vinyl acetate resin 10-75%, methyl vinyl silicone rubber 10-20%, Low Density Polyethylene 2-7%, process white 10-55%, ultra-fine fibre 1-10% Homogeneous phase mixing forms.
Embodiment 1
A kind of composite sound isolating material is characterized in that: the parts by weight proportioning of described material composition is: vinylchlorid
Vinyl acetate resin 50%, methyl vinyl silicone rubber 10%, Low Density Polyethylene 5%, process white 30%, ultra-fine fibre 8% Homogeneous phase mixing form.It is by the raw material mix and blend of predetermined proportion, at normal temperatures through first time mixing fusion, second time mixing make material mixing more even, carry out that secondary roll-in is mixing rolls the sheet material, the step such as sanction plate etc. that appropriate size and shape, make the vinyl chloride-vinyl acetate resin material that soundproof effect is good.
The outstanding feature of vinyl chloride-vinyl acetate resin sound-proof material of the present invention has the noise blocking lower frequency.During use, (such as the sound-proof material of automobile) can arrange in pairs or groups traditional weighting material or cotton, can block the noise (noise that such as automobile dynamic system or car body produce) of upper frequency, and then reach good soundproof effect.
Claims (2)
