no. 1 example

[0013] The present embodiment provides a kind of STPU plastic formula, and it is used in sole production material, and the product composition of this STPU plastic formula is:

[0014]

[0015]

[0016] Among them, SEBS is an ethylene-butene copolymer obtained by hydrogenating polybutadiene with polystyrene as the terminal segment. SEBS does not contain unsaturated double bonds, so it has good stability and aging resistance, and also has Good fluidity, good compatibility, and can also improve the weld line strength of the product. The POE is a copolymer of ethylene and octene, the PP is polypropylene (English name: Polypropylene), the AC is a foaming agent, and the BIBP is a vulcanizing agent.

no. 2 example

[0018] The present embodiment provides a kind of STPU plastic formula, and the product composition of this STPU plastic formula is:

[0019]

[0020] The invention also provides a preparation method of STPU plastic formula. During preparation, put SEBS and POE into the mixer first, then add PP, AC, BIBP, zinc oxide and tackifying resin into the mixer and stir evenly, and then add the mixture into the double Screw extruder extrusion granulation.

[0021] The beneficial effects of the STPU plastic formula and the preparation method thereof of the present invention are: using SEBS and POE as the main raw materials of the plastic formula, the prepared STPU plastic is cheap, high in yield, excellent in performance, environmentally friendly, light in specific gravity, good in elasticity, and effective Improve the physical properties of the sole and improve the comfort of the user. The product produced has a good anti-wrinkle effect. When molding the product, it can be directly fo...

Abstract

The invention discloses an STPU plastic formula applied to a production material of a sole. The STPU plastic formula comprises product ingredients as follows: SEBS (styrene-ethylene-butadiene-styrene), POE (polyolefin elastomer), PP (polypropylene), AC (azodicarbonamide), zinc oxide, BIBP and tackifying resin. The invention also provides a preparation method of the STPU plastic formula. During preparation, firstly, SEBS and POE are put in a stirring machine, PP, AC, BIBP, zinc oxide and the tackifying resin are added to the stirring machine to be stirred uniformly, and the mixture is added to a double-screw extruder for extrusion palletization. The prepared STPU plastic is cheap, high in yield, good in performance, environmentally friendly and light in specific gravity, the physical performance of the sole is effectively improved, the comfort of a user is improved, the prepared product has a good crease-resistant effect; during product forming, low-temperature injection modeling for direct foaming can be realized, the preparation method is simple to operate, foaming is conducted in a 1:1 mold during injection molding, and the accuracy of a formed finished product is high; besides, the tackifying resin is added to raw materials, and cohesion of the product is effectively increased.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a STPU plastic formula and a preparation method thereof. Background technique [0002] Shoes are a tool for people to protect their feet from injury, and shoes have been developed to the present, and shoes of various styles and functions can be seen everywhere. Shoes are mainly composed of soles and uppers. However, most of the existing sole materials are rubber, TPR, EVA and other materials, which are heavy, have poor physical properties, poor comfort, and are not environmentally friendly enough to satisfy consumers. usage requirements. Therefore, there is an urgent need for a new material that is environmentally friendly, non-toxic, and has good physical properties to replace traditional shoe sole materials. Contents of the invention [0003] Based on this, it is necessary to provide a STPU plastic formulation and a preparation method thereof to address the deficiencies in the prior art...
