Problems solved by technology

[0005] But existing floor decoration material mainly uses PVC material as lower floor (100), transparent layer (300) etc., owing to have halogen group element, although the propagating speed of flame is slow during fire, produces quite a lot of smog
Moreover, since it contains toxic phthalic acid-based plasticizers, environmental hormones and toxic gases (hydrogen chloride), etc. are produced during incineration or fire, and they remain almost permanently in the natural environment during landfill disposal. Problems that place a heavy burden on the environment

preparation example Construction

[0060] And, the present invention provides a kind of preparation method of flame-retardant floor decoration material, it is characterized in that:

[0061] The flame-retardant floor decoration material includes a lower layer, a substrate layer, a printing layer and a transparent layer from bottom to top, and the method includes:

[0062] (1) The lower layer preparation step is used to prepare the lower layer using a composition containing 100 parts by weight of polyvinyl acetal resin and 100-400 parts by weight of filler;

[0063] (2) substrate layer preparation step, for preparing the substrate layer made of glass fibers impregnated with PVC sol;

[0064] (3) A printing step for forming a printing layer by printing on the substrate layer or laminating a film or paper printed with a printed pattern to the substrate layer;

[0065] (4) transparent layer preparation step, for preparing a transparent layer made of transparent PVC film or transparent PET film; and

[0066] (5) A...

Embodiment 1

[0088] A transparent layer having a thickness of 0.2 mm was prepared by calender molding from a composition containing a PVC resin.

[0089] And, a composition including 100 parts by weight of polyvinyl butyral as a polyvinyl acetal resin and 150 parts by weight of calcium carbonate as a filler was calender-molded to prepare a lower layer having a thickness of 1.5 mm.

[0090] The PVC sol impregnated glass fiber plate (30g / m2) that forms by adding the polyvinyl chloride of 100 weight parts polyvinyl chloride, 60 weight parts dioctyl terephthalates, 100 weight parts calcium carbonate, 2 weight parts barium-zinc heat stabilizer of polymerization degree 1000 2 ), drying to prepare a substrate layer, and giving a printing pattern on its upper part by a gravure printing method to form a printing layer.

[0091] After that, after the substrate layer and the transparent layer on which the printing layer was formed were thermally pressed, the bottom surface of the substrate layer and ...

Embodiment 2

[0093] In Example 1, the composition of the lower layer was changed and prepared as follows.

[0094] A composition comprising 100 parts by weight of polyvinyl butyral as a polyvinyl acetal resin and 300 parts by weight of calcium carbonate as a filler was used to prepare a lower layer having a thickness of 1.5 mm by calender molding. Other than that, the components and processing methods of other layers are the same as in Example 1.

Abstract

The present invention relates to a flame-retardant floor decoration material comprising a lower layer, a base layer, a print layer, and a transparent layer, which are in order from bottom to top, wherein at least one of the layers contains a polyvinyl acetal resin. In addition, the present invention relates to a method for preparing a flame-retardant floor decoration material comprising a lower layer, a base layer, a print layer, and a transparent layer, which are in order from bottom to top, wherein the method comprises: (1) a lower layer preparation step for preparing a lower layer using a composition containing 100 parts by weight of a polyvinyl acetal resin and 100-400 parts by weight of a filler; (2) a base layer preparation step for preparing a base layer composed of a glass fiber immersed in a PVC sol; (3) a printing step for forming a print layer by printing the print layer on the base layer or binding a print pattern-printed film or paper to the base layer; (4) a transparent layer preparation step for preparing a transparent layer composed of a transparent PVC film or a PET film; and (5) a binding step for binding the layers such that the base layer with the print layer formed thereon is disposed between the lower layer and the transparent layer.

Description

technical field [0001] The present invention relates to a flame-retardant floor decoration material and its preparation method, in particular, to such a flame-retardant floor decoration material and its preparation method: by making at least one layer of the flame-retardant floor decoration material contain polyvinyl acetal Resin, thereby reducing the smoke density and toxic gas that occur due to the burning of the resin in the event of a fire, and the flame-retardant floor decoration material is excellent in flame retardancy. Background technique [0002] Recently, with the improvement of the quality of life, there has been an increasing interest in not only health but also environmentally friendly products. As an example, there is a tendency to gradually use environmentally friendly materials for floor decoration materials that are closely related to residential life. At the same time, restrictions on materials and the like used in the preparation of such floor finishing ...
