Boron nitride coating process for preventing graphite plate from being damaged
The invention discloses a boron nitride coating process for preventing a graphite plate from being damaged, and is characterized in comprising a formula of a boron nitride coating for preventing the graphite plate from being damaged. The formula comprises phenolic resin, zinc stearate, silicon powder and petroleum coke, and the percentage of the petroleum coke is 5.12-6.71%; the preparation methodfurther comprises the following preparation steps: a, adding zinc stearate and silicon powder into a stirrer, and fully mixing and stirring for 1 hour; b, after stirring in the step a is finished, adding phenolic resin and petroleum coke, and fully mixing and stirring for 1 hour; c, after stirring in the step b, discharging and screening; d, after screening is finished, adding alcohol by using asprinkling can, and uniformly sprinkling; and e, after the operations are finished, mixing, stirring and sieving again. By adopting the process, the preparation raw materials are reasonably designed and proportioned, and the product is obtained according to the process preparation steps, so that the problems of high price of boron nitride raw materials, consumption of a large amount of alkaline raw materials in later alkali treatment and great increase of the time and cost of the preparation process in the existing preparation process are solved.
本申请公开了一种防止石墨板损坏的氮化硼涂层工艺，其特征在于，包括一种防止石墨板损坏的氮化硼涂层配方，所述配方包括酚醛树脂、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％；还包括如下制备步骤：a、搅拌机内加入硬脂酸锌、硅粉，充分混合搅拌1小时；b、步骤a搅拌结束后，加入酚醛树脂、石油焦，充分混合搅拌1小时；c、步骤b搅拌后进行放料筛料工作；d、筛料结束后使用喷壶加入酒精均匀喷入；e、以上操作结束后再次进行混合搅拌过筛。采用本工艺，对制备原料进行合理设计配比，根据工艺制备步骤得到的产品，解决现有制备工艺中存在氮化硼原料价格高、后期碱处理同样耗费大量碱性原料而大大增加制备工艺的时间和成本的问题。
