Problems solved by technology

[0004] At the same time, the hydrofluoric acid-resistant coatings in the original special environment generally adopt the on-site casting technology. The products after casting have macroscopic defects such as air bubbles and pores, which are prone to leakage. Moreover, deformation will occur during the heat release process of the resin, forming cavities. , resulting in indicators such as hardness and flexural strength not meeting the requirements
[0005] The applicant Sichuan Qingchuan County Hongyuan Stone Industry Co., Ltd. applied for the application number: 201210228242.7 on July 4, 2012, and the application name: an invention patent for a hydrofluoric acid-resistant high-performance artificial functional composite plate and its preparation method. Although the composite plate product prepared by this invention patent has better effects of compression resistance, anti-seepage, and hydrofluoric acid resistance to a certain extent, it also has deformation during the production process due to the resin exothermic process, and During the production process, the fluidity of the resin is poor, and the resin inside the product is unevenly distributed, resulting in pores and other phenomena; and the amount of resin used in this production process is large, and the cost increases accordingly
