Abstract
The present invention relates to a kind of sound insulation rubber material, and it is mixed by each raw material of following parts by weight：30 40 parts of polyurethane powder；10 25 parts of Polystyrene powder；12 20 parts of stabilization agent；5 10 parts of plasticizer；58 parts of foaming agent；6 20 parts of flake asbestos；59 parts of glass fibre powder；26 parts of Zinc oxide powder；25 parts of uvioresistant synergist；13 parts of free radical scavenger.Beneficial effect is：Overcome deficiency of the sound insulation rubber material generally using PVC as main material in the prior art, the present invention is so that polyurethane and polystyrene is main materials and spoke is with inorganic material such as asbestos, glass fibre and zinc oxide, add the additives such as plasticizer, stabilization agent and UV resistant agent simultaneously, obtained sound insulation rubber material is substantially better than the existing soundproof effect using PVC as the rubber material of main material, while the weather resisteant of obtained acoustic material of the invention, decay resistance are more preferably.
Description
Technical field
The invention belongs to field of new materials, and in particular to a kind of sound insulation rubber material.
Background technology
Every material that can be used for blocking noise, is referred to as acoustic material.Acoustic material is multifarious, and daily people compare
It common are solid fragment of brick, reinforced concrete wall, plank, plasterboard, iron plate, deadening felt, fiberboard etc..On stricti jurise
Say, almost all of material all has deadening, and it is exactly the of different sizes of sound transmission loss between different materials that it, which is distinguished,.It is same
Kind material, because surface density is different, there is bigger change in its sound transmission loss.Sound transmission loss follows mass law principle, be exactly every
The intensive surface density of unit of sound material is bigger, and sound transmission loss is bigger, and surface density is proportional with sound transmission loss.
Acoustic material physically has certain elasticity, and when sound wave incident, just excited vibrational is propagated in interlayer.Work as sound wave
It is not vertical incidence, but during θ incidence at an angle with interlayer, acoustic wavefront reaches interlayer surface successively, and arrives first interlayer
Sound wave excites in interlayer flexural vibrations ripple laterally to be propagated along interlayer, if bending velocity of wave propagation and sound wave in air reach gradually every
When the gait of march of layer surface is consistent, sound wave just strengthens the vibration of bending wave, and this phenomenon claims coincidence effect.At this moment bending wave shakes
Dynamic degree of convergence is especially big, and the energy of radiative acoustic wave is also especially big into another side air, so as to reduce soundproof effect.Exist at present
When manufacturing acoustic material, it can be manufactured using different materials, and rubber is then one kind therein.And making sound insulation at present
During the rubber of material, usually used is exactly that simple PVC material is manufactured, and at most increases moulding dose and foaming agent, still
Rubber heat resistance, corrosion resistance and the ductility that above-mentioned formula is made is not high.
The content of the invention
The present invention provides a kind of sound insulation rubber material, it is desirable to provide a kind of soundproof effect is good, weathering, corrosion resistant acoustic mastic
Leather material.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of sound insulation rubber material, it is by following parts by weight
Several each raw materials mix：Polyurethane powder 30-40 parts；Polystyrene powder 10-25 parts；Stabilization agent 12-20 parts；Plasticizer
5-10 parts；Foaming agent 5-8 parts；Flake asbestos 6-20 parts；Glass fibre powder 5-9 parts；Zinc oxide powder 2-6 parts；Uvioresistant increases
Imitate agent 2-5 parts；Free radical scavenger 1-3 parts.
Optimal, above-mentioned sound insulation rubber material, is mixed by each raw material of following parts by weight：Polyurethane powder 30
Part；20 parts of Polystyrene powder；18 parts of stabilization agent；7 parts of plasticizer；6 parts of foaming agent；16 parts of flake asbestos；Glass fibre powder 5
Part；26 parts of Zinc oxide powder；5 parts of uvioresistant synergist；2 parts of free radical scavenger.
Optimal, the plasticizer is diisooctyl phthalate.
Optimal, the foaming agent is azo foaming agent or nitroso group foaming agent.
Optimal, the free radical scavenger is 1,4-benzoquinone.
Compared with prior art, the beneficial effects of the invention are as follows：Overcome in the prior art sound insulation rubber material generally with
PVC is the deficiency of main material, and the present invention is so that polyurethane and polystyrene is main materials and spoke is with nothings such as asbestos, glass fibre and zinc oxide
Machine material, while the additives such as plasticizer, stabilization agent and UV resistant agent are added, obtained sound insulation rubber material is substantially better than existing
Soundproof effect of some using PVC as the rubber material of main material, while the weather resisteant of obtained acoustic material of the invention, corrosion resistance
Can be more preferably.
