Embodiment 1

[0029] Add 14g of naphthalene, 21g of durene and 0.5g of Cu powder in sequence in a three-neck flask with a ground mouth, heat the oil bath to 100°C to melt the naphthalene and durene, and use magnetic stirring to form a liquid dispersion system containing Cu powder. Raise the temperature of the medium (water) in the ultrasonic cleaning machine to about 82° C., transfer the three-neck flask to the ultrasonic cleaning machine, and oscillate ultrasonically for 2 hours. Then transfer the three-neck flask to an oil bath, raise the temperature to about 180° C., add 1.3 g of PMP, and stir until the PMP is completely dissolved. Transfer the solution to a mold, and cool at room temperature until the mixed solvent is completely solidified. The solid dispersion system together with the mold is processed into a sheet with a diameter of 8 mm and a thickness of 2 mm by a lathe. Vacuum drying at 40°C for 5 days to obtain a density of about 50mg / cm 3 1. A Cu-doped low-density poly-4-methyl...

Abstract

A kind of foam material made from metal adulterated by low-density poly-4-methyl-pentylene and its preparation are disclosed. It is produced by: blending with the dissolvent / non-solvent system and metal power, heating and melting, forming the dispersive system including the metal power through stirring, dispersing the metal power using supersonic wave, putting in the poly-4-methyl-pentylene, shifting it into die after heated and dissolved, lower the temperature at a fixed rate, getting the need shapes from the solid mixture after condensation, vacuum drying or supercritical extraction. Its advantages include: good doped uniformity, large content of the doped element, realizable to adulterate one element or several elements.

Description

1. Technical field [0001] The invention belongs to the field of polymer foam material preparation, and in particular relates to a metal-doped low-density poly-4-methyl-1-pentene foam material and a preparation method thereof. 2. Background technology [0002] Because low-density polymer foam has a series of special properties such as low dielectric constant, low thermal conductivity, and high specific surface area, it is a very widely used functional material. Specific application fields include dielectric materials, heat insulation materials, catalyst supports, etc. Achieving metal doping in polymer foams can bring about some meaningful changes in the material's properties and broaden its range of potential applications. [0003] Most of the existing metal-doped polymer foams are prepared by doping with metal compounds, and some unnecessary impurity elements are also brought in when doping elements are added. Inhomogeneous dispersion of doping compounds in the foam. Due ...
