Example Embodiment

[0018] A method for preparing a graphene-enhanced thermal conductivity silicon carbide ceramic pot includes the following specific steps:

[0019] (1) Add 100g of silicon carbide powder, 1g of boron carbide powder, 8g of liquid phenolic resin, and 5g of graphene to the ball milling tank, and add 1.5-2 times the amount of absolute ethanol as the solvent, and each component is 30% A large amount of silicon carbide ceramic balls are used as the ball milling medium, and they are quickly milled in a ball mill for 15 minutes, and the ingredients are mixed uniformly;

[0020] (2) Put the ball-milled silicon carbide ceramic slurry into a vacuum drying box, dry at 50°C, then crush it in a grind, and pass through a 40-mesh standard sieve to obtain ceramic particles.

[0021] (3) Add the above ceramic particles to a mold made of mold steel, press one-way pressure at 20 MPa, and hold the pressure for 60 seconds to obtain a pre-pressed ceramic pot green body, and then pack the pre-pressed ceramic...

Abstract

The invention discloses a preparation method of a silicon carbide ceramic pot using graphene to enhance heat conductivity. The preparation method comprises the following steps of according to scientific and reasonable component proportional ratio, compounding silicon carbide micropowder, boron carbide micropowder, liquid phenolic resin, and graphene component; performing ball milling, granulating, isostatic pressing forming, non-pressure sintering and the like, so as to obtain the silicon carbide ceramic pot. The silicon carbide ceramic pot has the advantages that the density of a prepared blank is large, the uniformity is good, the strength is high, and the sintering can be performed through simple drying; by adopting the non-pressure sintering, the energy consumption is decreased. The preparation method has the advantages that the method is simple, the industrial control is convenient, the raw material cost is low and the obtaining is easy, and the non-toxic and non-harmful ceramic pot which can be in direct contact with food can be prepared; the heat conductivity is higher, the boiling time of foods is accelerated, and the energy-saving effect is realized.

Description

Technical field [0001] The invention relates to the technical field of daily ceramics, in particular to a method for preparing a silicon carbide ceramic pot with graphene-enhanced thermal conductivity. Background technique [0002] Daily-use ceramics, as the name suggests, refers to the porcelain used in daily life that is essential to people's daily life. It can be said that the production of daily-use ceramics is due to people's daily needs. In daily life, people touch the most and are also the most familiar porcelains, such as tableware, tea sets, coffee sets, wine sets, rice sets, etc. The glazed surface of daily-use porcelain is bright and easy to wash; it is chemically stable, and has certain resistance to acid, alkali, salt and carbon dioxide in the atmosphere. It is not easy to chemically react with these substances, does not rust and age, and is durable; Low water absorption rate. Use daily porcelain to store food. After sealing the mouth tightly, it can prevent the moi...
