Problems solved by technology

However, due to its large volume expansion coefficient, the application of this medium in airtight containers is subject to many restrictions. For example, under the condition of a relatively wide temperature range, due to the large volume expansion coefficient under low temperature and high temperature conditions, the low temperature performance is suitable. The high temperature performance does not meet the requirements, or the high temperature performance is suitable, but the low temperature does not meet the requirements.

Description

technical field [0001] The invention belongs to the field of clay, and relates to a clay and its preparation method and application. Background technique [0002] As a high-quality medium for dampers and buffers, elastic cement has good elasticity and damping characteristics. However, due to its large volume expansion coefficient, the application of this medium in airtight containers is subject to many restrictions. For example, under the condition of a relatively wide temperature range, due to the large volume expansion coefficient under low temperature and high temperature conditions, the low temperature performance is suitable. The high temperature performance does not meet the requirements, or the high temperature performance is suitable, but the low temperature does not meet the requirements.
