Problems solved by technology

Regardless of whether the above two methods are blending powders or adding powders as fillers to polymers, no matter how long the blending time is, it is impossible to ensure that the materials of each phase are truly evenly distributed, and the orientation of the powders is also random. The uniformity of the prepared composite functional material is greatly affected
"Powder compacting device and method for making rare earth alloy magnetic powder compact" disclosed in the invention patent with the patent application number 00119155.1 discloses a method of orienting the powder in a magnetic field and then pressing it. This method can make the powder distribution relatively Uniform, but does not guarantee that the oriented powder will not mess up during pressing

Embodiment 1

[0024] The inventive method adopts figure 1 The mold shown is used to prepare functional composites with magnetic properties, by figure 1 It can be seen that the mold includes a female mold 1, an upper male mold 5, a lower male mold 10, a heating wire 8, and a coil 9. The lower male mold 10 is inserted into the female mold 1 to form a mold cavity 11, and the upper male mold 5 is opposite to the mold cavity 11. It can be inserted into the mold cavity 11 to make the mold cavity 11 a closed space. In the female mold 1, a heating wire 8 and a cooling channel 2 are arranged, and a coil 9 for forming a magnetic field is surrounded outside the female mold 1. Inside the female mold 1 There are also through holes connected to the vacuum tube 3 and the liquid input tube 7 respectively, the vacuum control valve 4 is arranged in the through hole connected to the vacuum tube 3, and the liquid input control valve is arranged in the through hole connected to the liquid input tube 7 6. The v...

Embodiment 2

[0027]This embodiment is still realized by using the mold described in Embodiment 1, and what is to be prepared is a functional composite material of polymer semiconductor. When the functional composite material is stressed, the resistivity of the material can change. The specific steps of realizing the method of the present invention are as follows: open the liquid input control valve 6 on the female mold 1, input the N-200 type resin liquid in the mold cavity 11 through the liquid input pipe 7, and then transport the copper powder with an average particle diameter of 100 nm into In the mold cavity 11, the copper powder is located on the N-200 type resin liquid, and then the upper male mold 5 descends, so that the lower surface of the upper male mold 5 forms a closed space with the inner wall of the female mold 1 and the upper surface of the lower male mold 10, and then the female mold is opened. Vacuum the control valve 4 on the mold 1, and evacuate the mold cavity 11 through...

Embodiment 3

[0029] What is to be prepared in this embodiment is a semiconductor functional composite material. The specific steps for realizing the method of the present invention are as follows: put the sulfur powder in a glass test tube, place it in a heating furnace and heat it to 130°C to liquefy the sulfur, then add the iron powder preheated to 100°C with an average particle size of 80 μm In the test tube with liquid sulfur, since the specific gravity of iron is greater than that of sulfur, the iron powder is deposited in the liquid sulfur in the test tube under the action of gravity field, and the iron powder in the liquid sulfur is stirred slowly with a glass test rod to make the iron powder adsorb The gas is discharged, and the stirring is stopped after the gas is released. The deposition time is determined according to the needs, and then the test tube is taken out of the furnace to cool. After the sulfur in the test tube is solidified, the iron powder is in contact with each othe...

Abstract

The present invention provides a method for preparing functional composite material, which includes the following steps: firstly, placing the powder with functional action in a container cavity, applying field action to said powder, impregnating the powder with liquid material, finally solidifying the liquid material or firstly, placing the liquid material in the container cavity, then adding the powder with functional action into the container cavity in whith the liquid material is held, and applying field action to the power in the container cavity, and finally solidifying the liquid material. Said functional composite material can have the functions of electric conductivity, semi-conduction, superconductance, magnetism, piezoelectricity, damping, sound-absorbing, light sensation and thermal sensation, etc.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a functional composite material and a preparation method thereof. Background technique [0002] Functional composite materials refer to composite materials that provide other physical properties in addition to mechanical properties and include some chemical or biological properties, such as conductive, semiconducting, superconducting, magnetic, piezoelectric, damping, sound absorption, wave absorption, friction, Composite materials with photosensitive and heat-sensitive functions; functional composite materials are mainly composed of one or more functional bodies combined with a matrix. Most of the existing functional composite materials are composed of functional powder materials. To manufacture parts or bulk materials together, it is generally necessary to combine the powder particles together to form a green body through large compressive ...
