Embodiment 1

[0045] Take 15 grams of montmorillonite with the sample number PK802 after purification and sodium ion exchange modification, its average particle size is 2 μm, and the average emissivity of far-infrared radiation in the range of far-infrared wavelength 4 to 20 μm at 40 ° C is 0.919, the montmorillonite and CPL (caprolactam), H 2 O, H 3 PO 4 Mix according to the ratio of 15:1500:23.5:5.1 to carry out normal pressure polymerization. Blow with nitrogen for about 5 minutes, stir at 90°C for 1 to 3 hours, then raise the temperature to 260°C and dehydrate. Then pour in 15 C.C. of water at 260° C. for 1 hour. At 260°C, react for 5 hours. Blanking, cutting into pellets, washing with water until the CPL residual amount is less than 5 wt%, and drying to obtain the polymer / clay nanocomposite material containing far-infrared radiation function clay of the present invention. The micrographs of the scanning electron microscope were measured as figure 1 , it can be seen from the figur...

Embodiment 2

[0047] Manufacture the polymer / clay nanocomposite material that contains far-infrared radiation function clay of the present invention in the same manner as Example 1, but use the nontronite 15 grams that the sample number of sodium ion exchange modification is PK805 through purification, its The average particle size is 5 μm, and the average emissivity of far-infrared radiation in the range of far-infrared wavelength 4 to 20 μm at 40° C. is 0.927, replacing montmorillonite. Nontronite and CPL, H 2 O, H 3 PO 4 The mixing ratio was 15:1500:23.5:5.1. The micrographs taken by scanning electron microscope are as follows: figure 2 , it can be seen from the figure that the layered clay material is dispersed in the polymer matrix nylon 6 with a nanoscale size. And the average emissivity of far-infrared radiation measured at 40°C is 0.888.

Embodiment 3

[0049] Manufacture the macromolecule / clay nanocomposite material that contains far-infrared radiation functional clay of the present invention in the same manner as Example 1, but use is purified, and the sample number that sodium ion exchange is modified is CL11 sericite 15 grams, and its average The particle size is 5 μm, and the average emissivity of far-infrared radiation in the range of far-infrared wavelength 4 to 20 μm at 40° C. is 0.873, replacing montmorillonite. Sericite and CPL, H 2 O, H 3 PO 4 The mixing ratio was 15:1500:23.5:5.1. The micrographs taken by scanning electron microscope are as follows: image 3 , it can be seen from the figure that the layered clay material is dispersed in the polymer matrix nylon 6 with a nanoscale size. And the average emissivity of far-infrared radiation measured at 40°C is 0.847.

Abstract

The nano composite polymer/clay material includes polymer as basic material and laminated clay material with far infrared radiation emitting function. The laminated clay material in nano size is dispersed in the polymer as basic material. The nano composite polymer/clay material of the present invention has low hardness, capacity of being recovered, ability of emitting far infrared ray at 40 deg.c, lasting far infrared ray emitting function and other advantages, and may be used in synthetic fiber and fabric.

Description

technical field [0001] The invention relates to a polymer / clay nanocomposite material, in particular to a polymer / clay nanocomposite material containing far-infrared radiation functional clay. It can be applied to artificial fibers, fabrics, objects for heat preservation, health care warming patches, etc. Background technique [0002] Today in the 21st century, due to the increasing living standards of human beings, the requirements for clothing fabrics (such as hats, umbrellas, clothing) and housing (building materials, curtains) have gradually changed from just asking for food and clothing in the past to now paying attention to their health. The special functional requirements, and the far-infrared function with thermal storage function and health care requirements, is one of the most important requirements, and its product is far-infrared fiber. Far-infrared fiber is the abbreviation of far-infrared radiation function fiber. After the fiber absorbs body heat, it can emi...
