Abstract

The present application relates to the production field of polystyrene sheets, and specifically discloses an impact-resistant polystyrene sheet and a preparation method thereof. An impact-resistant polystyrene board is obtained by mixing the following raw materials in parts by mass: 110-130 parts of expandable polystyrene particles, 6-12 parts of silane coupling agent, casting slurry: 15-25 parts of white cement, 15-25 parts of heavy calcium carbonate, 8-13 parts of quartz powder, 75-85 parts of water, and 2-6 parts of initiator; the preparation method is: by modifying the expandable polyphenylene after silane coupling agent treatment The polystyrene substrate is made of vinyl particles, and then the casting slurry is injected into the cavity of the polystyrene substrate by means of vacuuming, and finally the casting slurry is cured in the cavity of the polystyrene substrate. The impact-resistant polystyrene board of the present application can be used in the production field of polystyrene boards, which has the advantage of impact resistance.

Description

technical field [0001] The present application relates to the production field of polystyrene boards, and more particularly, to an impact-resistant polystyrene board and a preparation method thereof. Background technique [0002] Polystyrene boards are usually used for external wall thermal insulation materials. Traditional external wall thermal insulation materials mainly include two types of thermal insulation materials: organic foam boards and inorganic thermal insulation materials. However, in traditional external wall thermal insulation materials, organic materials are not fireproof and inorganic materials are not thermal insulation. Therefore, adding inorganic materials to polystyrene boards can improve the performance of polystyrene boards as external wall thermal insulation materials, and further break the bottleneck of traditional external wall thermal insulation materials. [0003] At present, the preparation method of the existing polystyrene board includes the fo...
