SUPER-STRONG AND ANTI-SLIP COMPOSITE CARPET WITH THREE-DIMENSIONAL TPE ELASTIC STRUCTURE AND COMPOUNDING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/220488
Kind Code:
A1
Abstract:
Disclosed is a super-strong and anti-slip composite carpet with a three-dimensional TPE elastic structure, which is formed by compounding a fabric layer (1) and a TPE layer (2), wherein TPE is composed of 80-90% of a styrene oxide-butadiene block copolymer and 10-20% of a polypropylene, and the thickness of the TPE layer (2) is 1-2 mm. The compounding process therefor comprises the following steps: firstly, preheating the transparent TPE to 80ºC, then adding same to a material barrel of a casting machine, stirring the TPE via a screw, and heating same in a heating temperature ranging from 140ºC-200ºC and in 6-9 sections, such that the heated TPE forms a paste; secondly, extruding the paste-like TPE through a metal joining pipe into a die head; and thirdly, the paste-like TPE flowing in a planar cascade shape out through the die head, and at the same time, passing out together with the back part of the carpet fabric so as to be compounded between an embossed roller and a rubber roller, and subjecting same to compound forming with the bottom part of the fabric layer. The carpet has a good anti-slip effect and no edge warping, and is light resistant, aging resistant, non-toxic and tasteless, safe and reliable.
