The invention discloses an extrusion molding type heat preservation polystyrene foaming hard plate with a closed hole type structure. The extrusion molding type heat preservation polystyrene foaming hard plate comprises an upper hard layer, a lower hard layer and a supporting structure. The upper hard layer is slidably connected with the lower hard layer, the lower hard layer is provided with an accommodating cavity, the upper hard layer is provided with a clamping support, the clamping support and the upper hard layer are integrally formed. The clamping support is located in the accommodating cavity, the supporting structure is located in the accommodating cavity, and the supporting structure comprises an upper supporting plate, a lower supporting plate and a damping spring. When the upper hard layer bears the weight, the upper hard layer moves downwards relative to the lower hard layer, and the damping spring is compressed to provide a supporting force so as to reduce the gravity borne by the lower hard layer, so that the bearing capacity of the extrusion molding type heat preservation polystyrene foaming hard plate with the closed hole type structure is improved.
Description
technical field [0001] The invention relates to the technical field of hard boards, in particular to an extruded thermal insulation polystyrene foamed hard board with closed-cell structure. Background technique [0002] Hard board is a new type of light-weight floor decoration material that is very popular in the world today, also known as light-weight floor material. It is a popular product in Europe, America and Asia, Japan and South Korea. It is popular abroad. It began to enter the Chinese market, and has been widely recognized in large and medium-sized cities in China, and is widely used, such as families, hospitals, schools, office buildings, factories, public places, supermarkets, commercial and sports venues, etc., hard The board refers to the floor made of polyvinyl chloride material. Specifically, polyvinyl chloride and its copolymer resin are used as the main raw material, and fillers, plasticizers, stabilizers, colorants and other auxiliary materials are added. ...
