[0002] PS board, also known as polystyrene board, is a kind of thermoplastic plastic board, which is made of polystyrene as the main raw material and through a specific process such as extrusion. With the continuous progress of science and technology, the demand for PS board is increasing. To improve the slip resistance and stain resistance of PS board, a hardening liquid is applied to the surface of PS board during the processing of PS board, forming a hard protective film on the surface of PS board. This not only improves the surface hardness but also resists external abrasion, thereby prolonging the service life of PS board and ensuring its original gloss and transparency.
