Boron nitride coating formula for preventing graphite plate from being damaged
The invention discloses a boron nitride coating formula for preventing a graphite plate from being damaged, the boron nitride coating formula comprises phenolic resin, zinc stearate, silicon powder and petroleum coke, and the percentage of the petroleum coke is 5.12-6.71%. According to technical scheme of the invention, enterprise production cost is reduced, the usage amount of alkali treatment sodium hydroxide is reduced, excessive residual silicon is prevented from overflowing after the reaction silicon carbide product is fired and discharged from a furnace, and the product is easily separated from a sintered silicon wafer; a petroleum coke raw material is mainly adopted to replace a boron nitride raw material required in the silicon carbide reaction sintering process, petroleum coke isused for replacing boron nitride according to a formula sample, and meanwhile, the proportions of silicon wafers and other ingredients are adjusted according to the sample proportion, so that the alkali treatment time is shortened, and the service life of an alkali treatment furnace is prolonged.
本申请公开了一种防止石墨板损坏的氮化硼涂层配方，包括酚醛树脂、硬脂酸锌、硅粉和石油焦，其中石油焦的百分占比为5.12‑6.71％。本申请技术中，为降低企业生产成本，降低碱处理氢氧化钠使用量、避免反应碳化硅产品烧制出炉后多余残硅溢出和易分离产品与烧结后的硅片，主要采用一种石油焦原料来代替碳化硅反应烧结过程中需要的氮化硼原料，根据配方试样氮化硼使用石油焦代替，同时根据试样比例来调整硅片以及其余配料比例、改变来缩短碱处理处理时间，延长碱处理炉的寿命。
