In the said nonwoven layer away from being provided with impervious barrier between the layer 6 of watertight composition and the layer 5.

Impervious barrier solved effectively since horticultural covering film damaged or soak after the problem that thermal insulation quilt soaked or soak into, if horticultural covering film is damaged or soak, the bottom of thermal insulation quilt is soaked or soaks into, and can not soak or soak into other nonwoven layer again.

Said impervious barrier is fixed through layer 5, the layer 6 of heat seal and nonwoven layer, upwards fixes with the watertight composition heat seal after the bending around the impervious barrier.

Equally, layer 5, the layer 6 of impervious barrier and nonwoven layer are fixed through heat seal, have solved the problem that the back pinprick causes not antiseepage of thermal insulation quilt of making effectively.Simultaneously, because the upwards bending all around of impervious barrier, last and watertight composition heat seal is fixed, and can guarantee that rainwater can not enter in the thermal insulation quilt from the both sides of thermal insulation quilt.

Said impervious barrier is PVC thin layer or foaming rete.

The foaming rete has waterproof, protection against the tide, anti-freezing dew performance, and the fine and closely woven netted microvesicle that evenly distributes owing to film is inner has formed a barrier layer, has produced the iris action that cushions variations in temperature, reaches the purpose of waterproof, protection against the tide, anti-freezing dew.

The utility model is taked above technical scheme, has the following advantages: 1, solved and stayed the problem that pinprick can not waterproof after thermal insulation quilt is made; 2, solved the problem that thermal insulation quilt soaks inwards or soaks into from internal layer; 3, waterproof, good seepage-proof property; 4, cost is low, easy to process; 5, long service life.

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Description of drawings
