Problems solved by technology

However, due to the formation of the PVC foam layer of the PVC floor, the mechanical foaming method (mechanically injecting air into the PVC foaming sol, followed by gelation) has been used instead of the traditional chemical foaming method (mainly using azodicarbonate

Example Embodiment

[0044] Example 1

[0045] All layers except for the size-reinforcing layer 4 are formed by a calendering method.

[0046] (Forming the middle resin layer)

[0047] Use 100 parts by weight of polyvinyl chloride with a degree of polymerization of 1,000, 50 parts by weight of dioctyl phthalate, 2 parts by weight of epoxidized soybean oil, 1.8 parts by weight of barium zinc stabilizer, and 60 parts by weight of calcium carbonate as the intermediate resin Layer 5 raw material.

[0048] The above mixture was mixed in a Banbury heavy-duty twin-shaft mixer at 150°C, and then first mixing and second mixing were performed in a two-roll rolling mill at 150°C. Subsequently, the resulting mixture was formed into a sheet having a thickness of 0.3 mm using a calender.

[0049] (Form printing layer)

[0050] Use 100 parts by weight of polyvinyl chloride with a degree of polymerization of 1,000, 50 parts by weight of dioctyl phthalate, 2 parts by weight of epoxidized soybean oil...

Example Embodiment

[0064] Example 2

[0065] In the same manner as in Example 1, all layers except for the elastic foamed layer 6 were formed. The elastic foam layer 6 is formed according to the following method.

[0066] (Form an elastic foam layer)

[0067] Except for the components and contents of the raw materials, the elastic foamed layer 6 is formed in the same way as the intermediate resin layer 5 is formed. The raw materials used to form the elastic foam layer 6 are 100 parts by weight of polyvinyl chloride with a degree of polymerization of 1,000-1,700, 30 parts by weight of pre-crosslinked acrylonitrile-butadiene-polyvinyl chloride copolymer resin, and 10 parts by weight of ions. Crosslinked polymer (Surlyn, Dupont) as modified olefin resin, 15 parts by weight of thermoplastic polyurethane resin, 60 parts by weight of dioctyl phthalate as plasticizer, and 3 parts by weight of barium as foaming stabilizer Zinc stabilizer, 6 parts by weight of azodicarbonamide as a foaming...

Example Embodiment

[0068] Example 3

[0069] In the same manner as in Example 1, all layers except for the elastic foamed layer 6 were formed. The elastic foam layer 6 is formed according to the following method.

[0070] (Form an elastic foam layer)

[0071] The raw materials used to form the elastic foam layer 6 are 100 parts by weight of polyvinyl chloride with a degree of polymerization of 1,000-1,700, 30 parts by weight of pre-crosslinked acrylonitrile-butadiene-polyvinyl chloride copolymer resin, and 60 parts by weight as Dioctyl phthalate as a plasticizer, 3 parts by weight of barium zinc stabilizer as a foaming stabilizer, 6 parts by weight of azodicarbonamide as a foaming agent, 10 parts by weight of calcium carbonate, and 1 part by weight Parts of pigment. The above mixture was mixed in a Banbury heavy-duty twin-shaft mixer at 120°C, and then the first mixing and the second mixing were performed in a two-roll rolling mill at 150°C. Subsequently, the resulting mixture was...

Abstract

A floor covering with a sound damping function and a preparation method thereof are provided to maximize a sound damping function, an impact absorption, a restoring force and a repulsion elasticity which a conventional PVC floor covering does not have. The synthetic resin floor covering with a sound damping function comprises polyvinyl chloride; and an elastic foaming layer(6) containing a pre-crosslinked acrylonitrile butadiene-vinyl chloride copolymer resin. The synthetic resin floor covering with a sound damping function comprises an elastic foaming layer(6) further containing a modified olefin resin. The synthetic resin floor covering with a sound damping function comprises an elastic foaming layer(6) further containing an ethylene vinyl acetate resin(EVA) or thermoplastic urethane resin(TPU).

Description

technical field [0001] The invention relates to a sound-insulating floor and a method for preparing the same. The present invention provides a floor with special functions, which has superior properties such as sound insulation, impact absorption, elasticity and resilience compared with conventional PVC floors, thereby minimizing sound transmission between floors of an entire apartment. Background technique [0002] Many patent specifications disclose conventional soundproof materials made using waste fibers or tire chips, such as Korean Patent Unexamined Publication 1998-28832. According to the patent, waste fibers or tire fragments are mixed directly into the concrete structure, or they are mixed with an adhesive to make tiles, which are then laid on top of the concrete slab for sound insulation. However, the former method, that is, the method of directly mixing waste fiber or tire chips into the concrete structure, is time-consuming, and it requires a...
