Modification plan and schedule of polystyrene foamed plastic tile

With the appropriate modifier of polystyrene foam tiles modified, can be prepared at room temperature quick drying, water resistant time long aqueous emulsion waterproof coating. The process is simple, and it is convenient to adjust the viscosity of water. The waterproof coating can be used to replace the waterproof oil used in corrugated boxes, and it can be used in the waterproof of the fiber board.

P-nitrobenzoic acid (PnBA) is mainly used in the manufacture of fiber strength, pesticides, dyes, resin, metal surface rust agent, sunscreen agent, color film coupler and filter agent a variety of products. The waste foamed plastics can be prepared by nitration and oxidation. Using this method, the method has the advantages of easy to get raw material, simple process and high added value of products. It is suitable for promotion in township enterprises.

Along with the development of chemical industry, polystyrene foamed plastic tile is used as packaging materials, disposable tableware, etc.. A dose of liquid with a low boiling point after defoaming waste polystyrene foam into modified agent, foaming agent, catalyst, stabilizer, by heating the polystyrene beads pre foaming and in mould heating to prepare the with micro closed stomata hard polystyrene foam plastic plate. This board can be used alone, also can be in shape after the thin aluminum cladding made of aluminum plate. The thermal insulation performance of the good and the roofs of houses using actual test. The results showed that no frost and condensation phenomena and can reduce the engineering cost, construction and operation is convenient. Therefore, in the North heating area, the method of the production of polystyrene foam plastic insulation board has a wide range of uses and good prospects for development.
