Embodiment 1～13

[0052] Examples 1-13 provide a high wear-resistant barrier and moisture-permeable material, the formula of which is shown in Table 1 in parts by weight, and the preparation method is as follows:

[0053] (1) carbon nanotubes, ethanol and lauric acid are mixed according to the weight ratio of carbon nanotubes: ethanol: lauric acid=20:1:80, and stirred at 40°C to obtain an oily carbon nanotube mixture;

[0054] (2) Add HDPE, UHMWPE, processing aids, antioxidants and lubricants into the high mixer, and mix at 1000-2000rpm for 1-3 minutes to obtain a uniform premix;

[0055] (3) Put the premixed material into the twin-screw extruder for melt extrusion, inject the carbon nanotube mixture prepared in step (1) into the melting section, the temperature of each zone of the screw is 190-230°C, and vacuum out small molecular substances in two sections , the vacuum pressure is controlled below -0.06MPa, and vacuum granulation is used to produce a highly wear-resistant barrier moisture-per...

Abstract

The invention discloses a high-wear-resistance barrier moisture-permeable material as well as a preparation method and application thereof, and belongs to the technical field of protective materials. The high-wear-resistance barrier moisture-permeable material comprises the following components in parts by weight: 65-80 parts of HDPE (High-Density Polyethylene), 5-20 parts of UHMWPE (Ultra High Molecular Weight Polyethylene) and 0.2-1 part of carbon nanotubes, the weight-average molecular weight Mw of the HDPE is less than or equal to 300,000, and the weight-average molecular weight Mw of the UHMWPE is 500,000-1,000,000. By optimizing and selecting PE, the material with excellent film-forming property, wear resistance and barrier property is obtained. The carbon nanotubes are introduced into the PE material, so that the moisture permeability of the material is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of protective materials, and in particular relates to a high wear-resistant barrier and moisture-permeable material and its preparation method and application. Background technique [0002] In order to achieve a good virus barrier, the materials used to make protective clothing need to have excellent sealing performance, and excellent sealing performance will make it difficult for the gas and sweat discharged from the wearer's body to escape, especially the existence of sweat will greatly It affects the wearing comfort of protective clothing. Therefore, while ensuring good barrier performance of protective clothing, it is necessary to make it have good moisture permeability. [0003] Prior art CN 111690195 A discloses a nano-microporous membrane, a method for making a nano-microporous membrane and its application. By mixing polyolefin with a certain molecular weight and a processing aid in a certain proporti...
