The invention relates to an LSPC foamed sheet and a preparation method thereof, and belongs to the technical field of foamed materials. In order to solve the problems that an existing foamed stone-plastic plate is uneven in foam hole, insufficient in strength and prone to local collapse, a novel foam regulator is introduced into a PVC-based foaming system. According to the regulator, through hydrosilylation, ring opening and silane coupling reaction, a polysiloxane-alkyl ester functional structure is grafted on the surface of nano silicon dioxide, bubbles are induced to be uniformly nucleated by utilizing low surface tension of the functional structure, and bubbles are inhibited to be aggregated through an interface adhesion energy barrier, so that a uniform and fine closed-pore structure is formed. The density of the obtained LSPC board is reduced, and the LSPC board has excellent mechanical strength and high-temperature collapse resistance and is suitable for bearing, floor heating and other scenes.

The application discloses a kind of high transparent photochromic polyester film and preparation method thereof, the film is composed of photochromic polyester layer, the photochromic polyester layer contains in-situ polymerized, surface-modified inorganic photochromic nanoparticles, the haze of the film is ≤3%, color change occurs within 5 seconds under sunlight irradiation.The high transparent photochromic polyester film provided by the application has high transparency, fast color change, excellent stability and green environmental protection, etc., can meet the stringent requirements of intelligent window film, high-end anti-counterfeiting, optical devices and other fields, and has extremely high application value and market prospect.
