[0002] With the rapid development of social economy and the improvement of people's living conditions, the requirement for indoor constant temperature and heat preservation is getting higher and higher. The application of rock wool boards has greatly improved the comfort of people's housing, so the application of rock wool boards is becoming more and more extensive. Rock wool boards, also known as rock wool thermal insulation and decoration boards, are inorganic fiber boards mainly made of basalt and processed by high-temperature melting. Rock wool boards are ideal sound insulation materials. A large number of slender fibers form a porous connection structure, which can effectively absorb sound and reduce noise. Although rock wool itself has the characteristics of sound absorption and fire prevention.

[0003] However, the current composite rock wool board has no support frame inside, resulting in low strength of the composite rock wool board. When it is impacted or collided, it is easy to deform and damage. In view of the above problems, a composite rock wool board is proposed. Content of the Utility Model
