Heat-proof ring and preparation method thereof
The invention discloses a preparation method of a heat-proof ring. The preparation method comprises the following steps: weaving a carbon fiber fabric according to the shape and size of the heat-proof ring; cyclically compounding the carbon fiber fabric with the first silica sol to obtain a preform; the solid content of the first silica sol is 23%-50%, and the volume fraction of the carbon fiber fabric in the heat-proof ring is 10%-30%. The invention further discloses the heat-proof ring, the carbon fiber fabric is woven by imitating the shape and size of the heat-proof ring, and the heat-proof ring is obtained through composite forming. And the uniformity and consistency of the quartz matrix in the heat-proof ring are improved, the temperature and pressure of hot pressing treatment are reduced, the crystallization phenomenon is avoided, and the heat-proof performance and the mechanical performance of the heat-proof ring are improved.
本发明公开了一种防热环的制备方法，包括如下步骤：仿照防热环的形状和尺寸编织碳纤维织物；将碳纤维织物循环复合第一硅溶胶得到预制体；将预制体进行热压处理，得到防热环，其中，第一硅溶胶的固含量为23～50％，防热环中碳纤维织物的体积分数为10～30％，本发明还公开了一种防热环，本发明通过仿照防热环的形状和大小编织碳纤维织物，通过复合成型，提高了防热环的内部石英基体的均匀性和一致性、降低了热压处理的温度和压力，避免了析晶现象的发生，提高了防热环的防热性能和力学性能。
