Problems solved by technology

[0003] There are many problems in the current sound-absorbing and heat-insulating floor: (1) Since the sound-absorbing layer is not continuously produced, the thickness deviation is difficult to control, resulting in a large thickness deviation of the product; The stability is different, resulting in a more serious height difference after the pavement is used for a period of time, which affects the aesthetic effect; (3) The environmental protection is poor, and the sound-absorbing layer will emit an unpleasant smell after being soaked in water during use, which will affect people's physical and mental health; (4) It is not recyclable and can only be landfilled or incinerated, which causes great troubles for enterprises to dispose of waste, and is also extremely harmful to environmental protection
(5) The fire resistance performance is poor, and it will continue to burn when it leaves the fire source
(6) shock absorption but no heat insulation

Abstract

The invention discloses a sound-absorption heat-insulation floor and a processing method thereof. The floor comprises a surface layer and a bottom layer, wherein the bottom layer is attached under the surface layer, the surface layer comprises a polyvinyl chloride (PVC) sheet layer, the bottom layer comprises a PVC foaming coiled material layer, and the PVC foaming coiled material layer is a foaming coiled material layer added with glass fiber felt, a glass fiber net or non-woven fabrics. The processing method of the sound-absorption heat-insulation floor comprises the steps of preparing a PVC foaming coiled material, attaching, molding as well as checking quality and packaging, wherein the PVC foaming coiled material is obtained through foaming inside a high-temperature foaming furnace according to a chemical foaming principle. The sound-absorption heat-insulation floor is free from shrinkage and arching deformation phenomena after being laid, the product evenness is good, the sound-absorption and shock-absorption effect is good, the floor is environment-friendly, nontoxic and simple to recover, and the floor is not required to be separated separately.

Description

technical field [0001] The invention relates to an interior decoration material, in particular to a sound-absorbing and heat-insulating floor and a processing method thereof. Background technique [0002] In the fields of ground building materials and various decorations, people have increasingly higher requirements for sound absorption and heat preservation of ground materials, and sound-absorbing and heat-insulating floors have become an increasingly indispensable requirement for people. Vinyl foam sound-absorbing layer or cork compounded with PVC elastic floor. [0003] There are many problems in the current sound-absorbing and heat-insulating floor: (1) Since the sound-absorbing layer is not continuously produced, the thickness deviation is difficult to control, resulting in a large thickness deviation of the product; The stability is different, resulting in a more serious height difference after the pavement is used for a period of time, which affects the aesthetic eff...
