Problems solved by technology
The existing Teslin mesh covering material is mainly composed of PVC resin and various plasticizers, stabilizers, lubricants, and flame retardants. The material will release vinyl chloride monomer as the temperature increases during processing. , it is a toxic substance that seriously endangers human health, and the material will produce a lot of black smoke during combustion, and at the same time produce a large amount of harmful gases and substances such as hydrogen halide, pollute the surrounding environment, and cause personal injury to people; in addition Most of the additives used in this material contain harmful substances such as lead, cadmium, mercury, polybrominated biphenyl and polybrominated diphenyl ether, which are banned by developed countries and regions such as the European Union, Japan, and the United States.

Embodiment Construction
[0020] In order to better understand the present invention, examples are given to further describe the present invention.
[0021] Table 1 is the raw material component composition of embodiment 1~embodiment 6.
[0022] Table 1
[0023]
[0024]
[0025] The preparation method is as follows:
[0026] (1) Add the formula raw materials into the high-speed mixer in turn and mix evenly, without heating during the mixing process;
[0027] (2) Place the homogeneously mixed raw materials in an ordinary twin-screw extruder, extrude at 170°C to 195°C, draw strips, cool in a water tank, and granulate to obtain a thermoplastic elastomer material for replacing PVC-coated polyester filaments;
[0028] (3) Co-extruding the thermoplastic elastomer material and the polyester filament in an ordinary extruder can make the thermoplastic elastomer material of the present invention firmly coat the polyester filament to make a high-strength, elastic textile yarn product That is, Teslin mes...

The invention discloses a thermoplastic elastomer material for replacing polyvinyl chloride (PVC) coated polyester yarns and a preparation method thereof. The thermoplastic elastomer material consists of the following raw materials in part by weight: 50 to 80 parts of matrix resin, 5 to 20 parts of softening plasticizer, 3 to 15 parts of mineral filler, 5 to 15 parts of compatilizer, 0.2 to 2 parts of lubricant and 0.2 to 0.5 part of stabilizer. All the raw materials are mixed uniformly in a high-speed mixer according to the proportion, and the uniformly mixed raw materials are extruded, pulled, cooled and granulated on a common double-screw extruder to form the thermoplastic elastomer material for replacing the PVC coated polyester yarns. The invention has an obvious advantage that the thermoplastic elastomer material for replacing the PVC coated polyester yarns has no special requirement for the equipment in a coated polyester yarn extrusion processing technique, namely the conventional stand for PVC extrusion can meet the extrusion requirement of the thermoplastic elastomer material for replacing the PVC coated polyester yarns, so the production cost is saved for a manufacturer.
Description
technical field [0001] The invention relates to the field of polymer materials, more specifically a thermoplastic elastomer material which is co-extruded with polyester filaments and firmly covers polyester filaments. Background technique [0002] Teslin mesh fabric technology, with high-strength industrial polyester industrial tube wire as the inner core, and PVC coated sheath for the outside. Used in outdoor leisure products, beach chairs, bags, curtains and other products. The existing Teslin mesh covering material is mainly composed of PVC resin and various plasticizers, stabilizers, lubricants, and flame retardants. The material will release vinyl chloride monomer as the temperature increases during processing. , it is a toxic substance that seriously endangers human health, and the material will produce a lot of black smoke during combustion, and at the same time produce a large amount of harmful gases and substances such as hydrogen halide, pollute the surrounding en...
