Problems solved by technology

Products made of ceramic materials have the advantages of high temperature resistance, chemical corrosion resistance, high hardness, and high compressive strength, but the disadvantages are low tensile strength, poor plasticity and toughness, insufficient mechanical strength, poor wear resistance, and poor drop resistance. It is also easy to break; the advantages of products made of polymer materials are good plasticity and toughness, and light weight, but the disadvantages are flammable, easy to oxidize, easy to deform and low hardness, poor protective effect, and long-term use can easily cause surface gloss out of shape

Abstract

A ceramic polymer composite material is disclosed. The composite material comprises following components by mass: 47-85% of 3Y-ZrO2, 0-8% of polyethylene, 0-8% of polypropylene, 3-15% of paraffin, 0-10% of microcrystalline wax, 0.3-4% of a dispersant, 0-5% of a plasticizer, and 5-25% of graphite particles with the particle size of the graphite particles ranging from 1 [mu]m to 1 mm. The 3Y-ZrO2, the polyethylene, the polypropylene, the paraffin, the microcrystalline wax, the dispersant, the plasticizer and the graphite particles are sintered at a high temperature to obtain a ceramic material with a spongy porous crosslinking structure. The ceramic composite material with light weight and good toughness is formed by injecting the ceramic material with the spongy porous crosslinking structure into a polymer resin material. A preparing method of the ceramic polymer composite material is also disclosed.

Description

【Technical field】 [0001] The invention relates to the preparation of ceramic materials, in particular to a ceramic polymer composite material and a preparation method thereof. 【Background technique】 [0002] Existing mobile phone casings, watch casings, watch chains, accessories, etc. are mostly made of plastic, metal or glass materials. Parts made of plastic materials are very easy to wear and scratch; parts made of metal materials are very easy to Paint peeling or rusting will cause users to feel uncomfortable allergic reactions during use; while parts made of glass are easy to scratch and break, making them often poor in wear resistance, easy to scratch, and poor in drop resistance, easy to fall broken. [0003] Therefore, some common daily necessities that require decorative functions, such as mobile phone casings, watch casings, watch chains, and jewelry, choose to use ceramic materials or polymer materials. Products made of ceramic materials have the advantages of hi...
