Description

A kind of novel high recovery sponge

Technical field

The utility model relates to sponge technical field, specially a kind of novel high recovery sponge.

Background technique

Sponge is a kind of porous material, has good water imbibition, can be used in clean article, the common sponge of people It is made of wood cellulose fibers or foamed plastic polymer, in addition, also have the natural sponge made of spongia, most a couple of days Right sponge is used for clean body or drawing, in addition, respectively low-density is poly- there are also synthetic sponge made of three classes other materials Ether, polyvinyl alcohol and polyester.

Most of sponge usually makes for household, footwear material, clothes, the industries such as automobile and electronics, sponge in household industry For people to use at mattress, traditional mattress sponge is due to its own material problem, when people lie on mattress, is easy to absorb The heat that people distribute, thermal insulation effect is poor, and is easily deformed under long-time service, follows the string, and drops the comfort of people It is low, a kind of novel high recovery sponge is released thus.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of novel high recovery sponge, have high resilience, every The good advantage of temp effect solves the problems, such as traditional mattress sponge due to its own material, when people lie on mattress, is easy The heat that distributes of people is absorbed, thermal insulation effect is poor, and is easily deformed under long-time service, follows the string, and makes that people's is comfortable Property reduce the problem of.

The utility model provides the following technical solutions: a kind of novel high recovery sponge, including stretch-resistant layer, the OK a karaoke club are stretched The top of layer is compounded with puigging, and insulating layer is compounded at the top of the puigging, and high return is compounded at the top of the insulating layer Bullet layer, the top of the high resilient layer and the bottom of stretch-resistant layer are compounded with water absorption layer.

Preferably, the material of the stretch-resistant layer is natural rubber, and the elasticity modulus of the stretch-resistant layer is 1MPa- 3MPa, the relative density of the stretch-resistant layer are 0.94.

Preferably, the thickness value of the puigging is 2-3 centimetres, and the material of the puigging is polyurethane, the sound insulation The relative density of layer is 0.915, and the oise insulation factor of the puigging is 20dB-25d.

Preferably, the material of the insulating layer is alumina silicate fibre, fibre diameter≤4 of the insulating layer, the thermal insulation The thermal conductivity of layer is 0.037W/mK.

Preferably, the material of the high resilient layer is TPE, the relative density 0.9-1.1 of the high resilient layer, the height time The surface of bullet layer is pressure surface effect, and the use temperature of the high resilient layer is -50 DEG C -100 DEG C.

Preferably, the material of the water absorption layer is polyvinyl alcohol, and the moisture content of the fiber of the water absorption layer is up to 30%- 50%, the moisture percentage under the water absorption layer room temperature is 4.5%.

Be compared with the prior art, the utility model have it is following the utility model has the advantages that

1, the novel high recovery sponge makes it have extremely low heat by the way that the insulating layer made of alumina silicate fibre is arranged Conductance, and then make novel high recovery sponge that mattress be made and distributed downwards in use, the heat that people distribute can be obstructed, reduce heat The loss of amount, to achieve the purpose that novel high recovery sponge has good thermal insulation performance.

2, the novel high recovery sponge makes it have good high resilience by the way that the high resilient layer made of TPE is arranged Energy gas permeability and higher compression load ratio can generate the rebound of different support forces when being pressurized under different deformation state Power, power fatigability is good, therefore when people's use is fabricated to mattress by novel high recovery sponge, has very high comfort, To achieve the purpose that novel high recovery sponge has high resilience.

3, the novel high recovery sponge makes it have good sound-proofing by the way that the puigging made of polyurethane is arranged Can, make novel high recovery sponge when for door and window or bonnet, the propagation of sound can be obstructed, reduce the propagation of noise, To improve the sound insulation value of novel high recovery sponge.

4, the novel high recovery sponge has it at normal temperature by the way that the stretch-resistant layer made of natural rubber is arranged Good ductility be broken novel high recovery sponge will not when being squeezed or stretching, and can restore to the original state, and mention The service life of novel high recovery sponge is risen, to improve the tensile resistance of novel high recovery sponge.
