Top layer in the raw material on floor helps to ensure that the mechanical performance of sheet material, and sandwich layer is more beneficial for ensureing the heat-insulating property of sheet material.
To realize above-mentioned technique effect, the technical scheme is that：A kind of sandwich type Sound insulation flooringses, it is characterised in that
The first top layer, sandwich layer and the second top layer including stacking, sandwich layer are the raw material composition bag of cork layer, the first top layer and the second top layer
Include 10~20 parts of 40~60 parts of natural rubber, wood substance grain or powder, 20~40 parts of inorganic filler, vulcanization accelerator 0.05~
0.25 part, inorganic filler is selected from least one of diatomite, perlite, micropore ceramics powder, flyash.
Preferable technical scheme is that wood substance grain or powder are granulated cork and/or the chopped silk of flaxen fiber, or for selected from jade
At least one of rice stalk, wheat stalk, sesame stalk and cotton stalk, the particle diameter of wood pad is 40~100 mesh.
Preferable technical scheme is also to include 1~3 part of fire retardant, the fire retardant in the raw material of sandwich type Sound insulation flooringses
For phosphonium flame retardant, phosphonium flame retardant is selected from least one of APP, phosphate, phosphite ester, encapsulated red phosphorus.
Preferable technical scheme is that the thickness of cork layer is the 1/2~1/4 of floor layer thickness.
Preferable technical scheme is, vulcanization accelerator is selected from guanidine vulcanization accelerator, aldehyde amines vulcanization accelerator and secondary
At least one of sulfonamides vulcanization accelerator.
Preferable technical scheme is that vulcanization accelerator is that guanidine vulcanization accelerator and sulfenamide vulcanization accelerator combine
Form, the percentage by weight of sulfenamide vulcanization accelerator is 35~50% in vulcanization accelerator.
The advantages of the present invention are：
Sandwich type Sound insulation floor structure of the present invention is simple, by by soft high resilience and the good cork of heat preservation and soundproof performance
Layer is arranged in the first top layer and the second top layer, and the natural rubber in the first top layer and the second top layer has certain elasticity, because
This gained plate surface has certain elasticity, in top layer the inorganic filler with micropore also contribute to improve the sound-proofing on floor
Energy.
Embodiment
