preparation example Construction

[0031] The present invention also provides a kind of preparation method of high-temperature anti-stick coating, and it comprises the following steps:

[0032] Step S101, adding PEG6000 into high-purity water and stirring until all PEG6000 is dissolved.

[0033] In this embodiment, stirring is carried out in a stirring manner without bubbles, so as to improve the continuity and smoothness of the high-temperature anti-sticking coating during coating. Wherein, the stirring time is 0.5 hour to 1 hour. Preferably, the stirring time is 1 hour. Preferably, it can be stirred while heating. It can be understood that in other embodiments, the stirring is also performed in a manner that no air bubbles appear.

[0034] Step S102, while stirring, slowly add Tween-80 into the high-purity water in which PEG6000 is dissolved, and stop stirring until the solution turns milky white.

[0035] Step S103, adding metal oxide powder and yttrium oxide powder into the milky white solution and stir...

Embodiment 1

[0049]Add 98g of PEG6000 into 940g of high-purity water and stir for 1 hour to completely dissolve; then continue to slowly add 188g of Tween-80 while stirring until the solution turns milky white, then stop stirring; Add a total of 579g of zirconia powder and yttrium oxide powder to the solution and stir until dispersed, wherein the mass ratio of zirconia powder to yttrium oxide powder is 509:70; then continue to add 157g of graphite milk and stir until dispersed; finally add 38g of n-butanol and stirred uniformly to form a suspension; the above-mentioned uniformly stirred suspension was placed in a ball mill and stirred for 4 hours, thereby obtaining the high-temperature anti-sticking coating. Mix the above-mentioned high-temperature anti-stick coating with water at a mass ratio of 1:1; apply the above-mentioned high-temperature anti-stick coating mixed with water evenly on the surface of a graphite boat to form a coating, and dry it naturally for 2 days to obtain The high-t...

Embodiment 2

[0052] Add 94g of PEG6000 into 789.4g of high-purity water and stir for 1 hour without a large number of bubbles to dissolve it; then continue to slowly add 157.8g of Tween-80 while stirring until the solution turns milky white and then stop stirring; Add a total of 640g of zirconia powder and yttrium oxide powder to the milky white solution and stir until dispersed, wherein the mass ratio of zirconia powder to yttrium oxide powder is 7:1; then continue to add 283.1g of graphite milk and stir until dispersed Finally, 35.7g of n-butanol was added and stirred uniformly to form a suspension; the uniformly stirred suspension was placed in a ball mill and stirred for 4 hours to obtain the high-temperature anti-sticking coating. Mix the above-mentioned high-temperature anti-stick coating with water at a mass ratio of 1:1; apply the above-mentioned high-temperature anti-stick coating mixed with water evenly on the surface of a graphite boat to form a coating, and dry it naturally for ...

Abstract

The invention discloses high-temperature anti-sticking coating. The high-temperature anti-sticking coating is prepared from the following components: high purity water, n-butanol, PEG6000, aquadag, tween-80, yttrium oxide powder and metal oxide powder, wherein the metal oxide powder is one or more of alumina powder, zirconia powder and titanium oxide powder. The invention further provides a preparation method of the high-temperature anti-sticking coating, a high-temperature anti-sticking vessel and a preparation method of the high-temperature anti-sticking vessel, so that the problems of carburization and bonding during sintering of cemented carbide are avoided.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to a high-temperature anti-stick coating and a preparation method thereof, as well as a high-temperature anti-stick utensil using the high-temperature anti-stick coating and a preparation method thereof. Background technique [0002] Cemented carbide sintering is carried out under high temperature and pressure, involving many complex chemical reactions and a liquid phase. Because graphite boats are durable and have good stability at high temperatures, they are widely used in the same industry. However, due to the small wetting angle between cemented carbide and graphite, it is easy to make the product and the boat under high temperature liquid phase. The boats are bonded together, resulting in carburization of the product, sticking and deformation of the boat, and the damage rate of the boat is extremely high. Therefore, an isolation layer must be set between the produc...
