[0042] see figure 1 , figure 1 It is a flow chart of the preparation method of the ceramic polymer composite material provided in the embodiment of the present application. The ceramic polymer composite material can be the ceramic polymer composite material described in any of the above-mentioned embodiments, and the preparation method of the ceramic polymer composite material can include:

[0043] 110. Provide a first raw material, the first raw material includes a ceramic material and an organic small molecule dispersant, and mix the first raw material to obtain an inorganic composite material;

[0044] 120. Provide a second raw material, the second raw material includes an inorganic composite material and a prepolymer resin dispersant, and mix the second raw material to obtain a premix;

[0045] 130. Provide a third raw material, where the third raw material includes a premixed material and a polymer material, and mix the third raw material to obtain a ceramic-polymer com...

Embodiment 1

[0069] A ceramic polymer composite material, in parts by weight, comprising: 20 parts of polymer material, 70 parts of ceramic material, and 1.25 parts of dispersant;

[0070] The polymer material is polyphenylene sulfide, the ceramic material is zirconia with a particle size of 1 μm to 5 μm, the dispersant includes amino KH550 and epoxy resin with a molecular weight of 200 to 1500, and the mass ratio of amino KH550 to epoxy resin is 1: 2.

Embodiment 2

[0072] A ceramic polymer composite material, in parts by weight, comprising: 20 parts of polymer material, 70 parts of ceramic material, 1.25 parts of dispersant, 3 parts of pigment, 0.1 part of antioxidant, 0.15 part of lubricant, 2 parts of toughening agent share;

[0073] The polymer material is polyphenylene sulfide, the ceramic material is zirconia with a particle size of 0.5 μm to 5 μm, the dispersant includes amino KH550 and epoxy resin with a molecular weight of 200 to 1500, and the mass ratio of amino KH550 to epoxy resin is 1 : 2, the pigment is titanium dioxide, the antioxidant is pentaerythritol tetrakis (3-lauryl thiopropionate), the lubricant is pentaerythritol stearate, and the toughening agent is epoxy resin.

[0074] It can be seen that the difference between Example 2 and Example 1 is that: 3 parts of pigment, 0.1 part of antioxidant, 0.15 part of lubricant, and 2 parts of toughening agent are added.

Abstract

The embodiment of the invention provides a ceramic polymer composite material and a preparation method thereof, a shell and a preparation method thereof, and electronic equipment. The ceramic polymer composite material comprises the following components in parts by weight: 10-30 parts of a polymer material, 60-80 parts of a ceramic material and 0.5-2 parts of a dispersing agent. The dispersing agent comprises an organic small molecule dispersing agent and a prepolymer resin dispersing agent, and the mass ratio of the organic small molecule dispersing agent to the prepolymer resin dispersing agent is (0.3-1): (0.1-5). The organic small molecule dispersing agent comprises one or more of a coupling agent and triethylamine, the prepolymer resin dispersing agent comprises one or more of epoxy resin, polyacrylic resin and polyimide resin, and the molecular weight of the prepolymer resin dispersing agent is 300-5000. According to the embodiment of the invention, the organic small molecule dispersing agent and the prepolymer resin dispersing agent are used together, so that the melt flowability of the ceramic polymer composite material can be improved, and the processability of the ceramic polymer composite material is improved.

Description

technical field [0001] The present application relates to the technical field of composite materials, in particular to a ceramic polymer composite material and a preparation method thereof, a casing and a preparation method thereof, and electronic equipment. Background technique [0002] With the development and progress of materials and technology, the appearance of mobile phones and other terminals is changing faster and faster. Ceramic materials are loved by more and more consumers because of their high hardness, high toughness and gentle texture like jade. At present, structural parts made of ceramic materials have been applied to appearance structural parts such as covers of various mobile phones and smart wearables. However, the use of ceramic materials to make mobile phone casings has the following problems: 1) The production cycle is long, and the sintering process takes at least one week; 2) The production cost is high, and a set of ceramic battery covers requires a...
