Problems solved by technology

[0004] However, the existing floor materials contain toxic phthalate plasticizers because they mainly use PVC materials. Therefore, harmful substances such as environmental hormones and toxic gases (hydrogen chloride) are released when incinerated or fired, and they are buried and discarded. Sometimes it can remain almost permanently in the natural environment, so there is a problem of placing a large burden on the environment
[0005] And, for the floor material, although the surface treatment layer is formed thereon to prevent scratches and stains, the surface treatment layer is gradually worn away and may disappear as time goes by, and in this case, the laminated The transparent PVC layer formed on the lower part is exposed to the outside, and when the transparent PVC layer of this PVC material directly contacts the human body, there is a problem that harmful substances released from the PVC material have adverse effects on the human body.

Embodiment 1

[0130] From the bottom to the top, the balance layer 10, buffer layer 20, backing paper layer 30, dimensionally stable layer 40, printing layer 50, transparent layer 60, elastic layer 70', and surface treatment layer 80 are stacked in sequence, and the transparent layer 60 A transparent PVC film is used, and the elastic layer 70' uses an elastic layer in which a composite resin of acrylic elastic resin and polylactic acid is mixed at a mixing ratio (weight ratio) of 60:40, and based on 100 parts by weight of the composite resin, The PEwax of 1 weight part of resin meter as lubricant has been mixed, and the elastic layer of making with the thickness of 0.2mm, thus made the buffer floor material 1 (referring to that the total thickness of the present invention is 4.5mm) Figure 5 ).

Embodiment 2

[0132] In Example 1, the same method as in Example 1 was carried out except that the elastic layer 70' manufactured with a thickness of 0.5 mm was used instead of the transparent layer 60.

experiment example 1

[0136] The TVOC (Total Volatile Organic Compounds) emission of the buffer floor materials of Examples 1 and 2, and the commercialized existing floor material (Comparative Example 1) in which the transparent layer 60 constitutes the surface layer was compared. , and the results are shown in Table 1 below.

[0137] The measurement method of TVOC emission is carried out according to the Ministry of Environment Announcement No. 2010-24, the small chamber method of the indoor air quality engineering experiment standard, and the sample of the floor material as the experimental material is put into the mass spectrometer / high performance liquid In a small chamber with a volume of 20 L connected to chromatography (MS / HPLC), the TVOC released from the sample is collected from the small chamber and directly flows into the mass spectrometer / high performance liquid chromatography, thereby determining the The method of TVOC in the inflowing air is carried out, and other experimental conditi...

Abstract

The present invention relates to a cushioning flooring material and a manufacturing method therefor, and more particularly, to a cushioning flooring material which is non-toxic, eco-friendly, and excellent in sound insulation performance by applying an elastic layer including an acryl-based elastic resin or a composite resin comprising an acryl-based elastic resin and polylactic acid as a surface layer forming the cushioning flooring material, so that a user is not exposed to harmful substances even when a surface treatment layer, disposed on the upper portion of the surface layer, is worn out and the surface layer is exposed, and a manufacturing method therefor.

Description

technical field [0001] The present invention relates to a buffer floor material and a manufacturing method thereof, and more particularly, to a method in which an elastic layer comprising an acrylic elastic resin or a composite resin containing an acrylic elastic resin and polylactic acid is used as a material for constituting a buffer floor material A surface layer whereby the user is not exposed to harmful substances even when the surface treatment layer on the upper part of the surface layer is worn to expose the surface layer, and is non-toxic, environmentally friendly, and excellent in sound insulation Cushioning floor material and method of manufacture thereof. Background technique [0002] Recently, with the improvement of the quality of life, there is an increasing interest in not only health but also eco-friendly products. As an example, flooring materials that are closely related to residential life are increasingly using materials that can impart environmental pr...
