Description

Technical field:

[0001] The invention relates to a building board, in particular to a sound-insulating polystyrene foam board and a preparation method thereof. Background technique:

[0002] Polystyrene (Polystyrene, abbreviated as PS) refers to a polymer synthesized by free radical addition polymerization of styrene monomer. It is a colorless and transparent thermoplastic with a glass transition temperature higher than 100°C. Ordinary polystyrene resin is an amorphous polymer. The side groups of polystyrene macromolecular chains are benzene rings, and the random arrangement of bulky side groups is benzene rings, which determines the physical and chemical properties of polystyrene, such as high transparency. , high rigidity, high glass transition temperature, brittle and so on. Expandable polystyrene is made by impregnating low-boiling point physical blowing agent in ordinary polystyrene. It is heated and foamed during processing. It is specially used to make foam plastic p...
