Abstract

The invention provides a high-strength, high-toughness and high-temperature-resistant artificial stone plate material and a preparation method thereof. The artificial stone plate material comprises the following components in parts by mass: 10-14 parts of a polyacrylonitrile PAN-based carbon fiber powder, 4-6 parts of a microsilicon powder, 52-54 parts of white portland cement and 28-32 parts of modified resin, wherein the modified resin is formed by mixing 40% of first-order thermosetting phenolic resin and 60% of diphenol propane-type epoxy resin. Phenomena that the plate material is easy tofracture and break during mounting, transportation or use and is easy to deform or burst in case of high temperature and the like are effectively prevented, and the service life of the plate materialcan be effectively prolonged.

Description

technical field [0001] The invention relates to the field of artificial stone, in particular to a high-strength, high-toughness and high-temperature-resistant artificial stone plate and a preparation method thereof. Background technique [0002] Artificial stone is a mineral-filled polymer composite material that is vacuum-cast or molded from natural ore powder, high-performance resin and natural pigments. It can be widely used in public buildings and home decoration. It is a non-radioactive pollution-free Environmentally friendly and green new building interior decoration materials that can be reused. However, the existing artificial stone slabs are not high in strength, low in toughness, and poor in high temperature resistance. They are prone to fracture and fragmentation during installation, transportation or use, and are prone to deformation or even bursting when encountering high temperatures. Contents of the invention [0003] In order to overcome the above problems...
