Problems solved by technology

[0002] At present, most block carpets are covered with PVC or asphalt. The carpet with asphalt has poor temperature resistance, easy to crack in winter, easy to dissolve in summer, and has poor foot feel.
In addition, most of the domestic PVC tiled carpets contain the plasticizer dioctyl phthalate (DOP), which is harmful to the environment due to its phthalate content, and cannot meet the environmental protection requirements for export to the United States and the European Union.

Abstract

The invention discloses an environment-friendly carpet, which is formed by a carpet side and a gum side, wherein the gum side is separated into an upper gum layer and a lower gum layer, and the lower gum layer is prepared from the following raw materials in parts by weight: 200 parts of PVC (polyvinyl chloride) paste resin, 700 parts of calcium carbonate with the particle size between 100 and 120 meshes, 180 parts of dioctyl terephthalate, 2 parts of heat stabilizer, 15 parts of viscosity reducer, and 1 part of carbon black. The preparation process of the environment-friendly carpet comprises the following steps of: (1) preparing a PVC gum material; (2) preparing a complete gum side by the prepared PVC gum material, coating the carpet side on the upper gum layer of the gum side, pressing the carpet side to the gum side, and feeding into a drier; and (3) performing conventional air cooling, roller cooling and air-conditioner cooling after the product is taken out from the drier to prepare a finished product. The non-toxic dioctyl terephthalate is adopted as a plasticizing agent instead of a conventional toxic plasticizing agent, so that the carpet is harmless to the environment, and has the advantages of good temperature resistance, cracking resistance in winter, dissolving resistance in summer and good foot feel.

Description

technical field [0001] The invention relates to an environment-friendly carpet. Background technique [0002] At present, patchwork carpets are mostly covered with PVC or asphalt. Carpets covered with asphalt have poor temperature resistance, are easy to crack in winter, dissolve easily in summer, and have poor foot feel. In addition, most domestic PVC tiled carpets contain the plasticizer dioctyl phthalate (DOP), which is harmful to the environment due to its o-phthalate content, and cannot meet the environmental protection requirements for export to the United States and the European Union. Contents of the invention [0003] Aiming at the above-mentioned prior art, the present invention provides an environment-friendly carpet, which has a simple preparation process, and the obtained carpet is environment-friendly and comfortable, and can meet the environmental protection requirements for export to the United States and the European Union. [0004] The present invention ...
