Electric heating floor rug and method of manufacturing same

Abstract

An electric carpet is formed by laminating a surface material 1, a surface heating element 2, a heat insulating rear material 3 and an anti- slippage material 4 with a nature of preventing slippage. The anti-slippage material is made of a resin material with a styrene-butadiene rubber added to an olefin based resin. As compared with the material 4 comprising an SBR resin as a whole, this anti-slippage material properly resists thermal aging while eliminating adhesion on the floor even with a rise in the temperature. As compared with the material 4 comprising an acrylic resin as a whole, this also eliminates the adhesion to the floor even with a rise in the temperature as caused by failure in the intensifying of coagulation forces. As compared with the material 4 comprising a vinyl chloride resin as a whole, with no phenomenon of transferring a plasticizer or the like, this further eliminates transfer of color onto the floor. The invention provides an electric carpet which eliminates adhesion to the floor even with a rise in the temperature along with a proper resistance to thermal degradation, achieves a better production environment without complicating the production equipment and further eliminate color transfer.

Description

technical field [0001] The invention relates to an electric heating carpet laid on a residential floor and used as a heating appliance and a manufacturing method thereof. Background technique [0002] In recent years, wooden floors have been used to replace tatami mats on residential floors, and since the backing of electric heating carpets is mostly formed by non-woven fabrics (hereinafter sometimes referred to as felts) composed of polyester fibers, so when used on wood When the electric heating carpet is laid on the floor, it is easy to slip and will move with people's walking. For this reason, it is proposed to laminate a layer of non-slip material under the underlayment (floor side surface) to prevent the electric heating carpet from moving with walking. (For example, refer to Patent Document 1) [0003] Figure 6 It is the electric heating carpet in the past. This electric heating carpet has an electric heating carpet main body 10 and a controller 11 . The controll...

Problems solved by technology

[0009] Specifically, when the anti-slip material 4 is made of SBR resin, its heat resistance is poor, and it is prone to thermal deterioration. When the temperature rises, it will be bonded to the floor, requiring a cross-linking manufacturing process, which leads to complex manufacturing equipment.

In addition, the problem with the non-slip material 4 made of acrylic resin is that its cohesive force will increase and it will stick to the floor after the temperature rises, and it needs to be heated to volatilize the solvent after coating the material that dissolves the acrylic resin in the solvent, which will Seriously affect the working environment and complex manufacturing equipment

When the non-slip material 4 is made of polyvinyl chloride resin, if the floor is made of polyvinyl chloride resin, the plasticizer contained in the polyvinyl chloride resin anti-slip material will transfer to cause color shift and pollute the floor, especially when the temperature is high. When rising, color shift occurs in a short time, and after coating the gel-like polyvinyl chloride resin on the substrate 3, it needs to be heated and formed, and the manufacturing equipment is complicated.
