Description
Technical field
The application relates to acoustical material, relates in particular to a kind of underfloor acoustical material that is layed in.
Background technology
Acoustical material especially is layed in underfloor acoustical material, is generally formed by gum particle mixing sticker bonding.Material composition is single, but sound-absorbing effect is not good enough.In addition; The gum acoustical material is frangible not; Behind the ceramic tile or stone floor laying completion of surface layer; Because the degree of expanding with heat and contract with cold of ceramic tile or stone floor is less than the rubber acoustical material of lower floor, after the contraction of lower floor's acoustical material or expansion can cause ceramic tile or the stone floor and the fracture of the seam crossing between them of surface layer.
Summary of the invention
In view of this, the purpose of the application embodiment provides a kind of acoustical material with preferable sound-absorbing effect, and said acoustical material is difficult for causing breaking of surface layer floor when conduct is layed in underfloor interlayer.
The application embodiment has disclosed a kind of acoustical material and has been formed by two or more material medium mixing sticker.Said material medium comprises rubber medium and other media such as cork.Said rubber medium can show as rubber foam (or be called " rubber pange ") and rubber grain.At least a portion of said material medium is processed by salvage material.For example, at least a portion of said rubber foam and rubber grain can derive from the elastomeric material of multiple waste and old recycling.Said acoustical material can be used as interlayer and is layed between surface layer floor and the ground after being compressed to coiled material.
Existing acoustical material is generally formed by gum particle mixing PU sticker bonding, and material composition is single, but sound-absorbing effect is not good enough.The acoustical material that the application embodiment discloses is made up of multiple material medium.Research shows that sound wave has incident angle and reflection angle when running into medium.Different medium, reflection angle is different with incident angle.Because the multimedium acoustical material has multiple medium, when sound wave runs into these different mediums, can produce incidence angles and reflection angle, the sound wave between incidence angles and the reflection angle can be cancelled each other, thereby reaches the effect of sound insulation.Except that superior sound absorption properties, said acoustical material also has fire-retardant and antibiotic advantage.
