preparation example Construction

[0064] The preparation method of degradable antifouling thermoplastic micro-airbag polymer elastomer material may preferably comprise the following steps:

[0065] (1) Feed polymer raw materials, nucleating agents and environmentally friendly degradable organic perfluorinated materials from the feed port at the front end of the twin-screw extruder, and feed the foaming agent from the feed port in the middle of the twin-screw extruder, so that the raw materials are heated After the melting and mixing are sufficient, it enters the static mixer for further homogenization, and then is pressure-controlled and quantitatively transported by the melt pump;

[0066] (2) The hot melt pumped out by the melt pump enters the underwater pelletizing chamber through the die head to be pelletized, and is taken out by the process water for separation, and the obtained pellets are screened and dried to form the target product.

[0067] More preferably as the preferred technical solution above, t...

Abstract

The invention relates to a degradable antifouling thermoplastic micro-airbag polymer elastomer material which is prepared from the following ingredients in percentage by weight: 88 to 98% of polymer raw material, 0.05 to 0.5% of nucleating agent, 0.4 to 2% of foaming agent and 0.1 to 10% of environment-friendly degradable organic perfluorosebacamidine material. A preparation method specifically comprises the steps: (1) feeding the polymer raw material, the nucleating agent and the environment-friendly degradable organic perfluorosebacamidine material from a feeding opening in the front end of a twin-screw extruder, feeding the foaming agent from a feeding opening in a middle section of the twin-screw extruder, hot melting and fully mixing all the raw materials, then sending into a static mixer to be further homogenized and then controlling pressure and quantitatively conveying by a melt pump; (2) sending hot melt sent out by the melt pump into an underwater pelletizing chamber to be pelletized, bringing out by technological water to be separated and screening and drying the particles to obtain a target product. Compared with the prior art, the degradable antifouling thermoplastic micro-airbag polymer elastomer material disclosed by the invention effectively achieves performance of antifouling, soiling-resistant, oil-resistant, contamination-resistant, attractive and good touch and is especially suitable for being applied to the fields of shoe materials, food package and the like.

Description

technical field [0001] The invention relates to the field of polymer material preparation, in particular to a degradable antifouling thermoplastic micro-airbag polymer elastomer material and its preparation. Background technique [0002] Thermoplastic polymer elastic materials are widely used in the manufacture of production and living facilities, equipment, tools and consumables. With the development of society to meet the requirements of environmental protection, energy saving and consumption reduction, the demand for lightweight materials has become more and more urgent. Thermoplastic polymer elastic materials have also begun a large number of lightweight experiments and verifications and continued to promote their applications. However, when thermoplastic foamed polymer elastomers are directly applied to direct consumer goods, without modification and special preparation, the conductivity of thermoplastic foamed polymers is generally greater than 10 to the 11th power and...
