The invention relates to a polystyrene modifying plastic which comprises the following ingredients in parts by weight: 50 parts of polystyrene, 1 part of tert-amyl methyl ether, 2 parts of polyoxyethylene nonyl phenyl ether, 2 parts of antimony trioxide, 3 parts of a plasticizer, and 1 part of a brominated flame retardant, and further comprises 4 parts of polyropylene cellulose. The polystyrene modifying plastic has the advantages that a polystyrene insulation board can be effectively prevented from shrinking due to heat at an early stage; the mechanical strength as well as the crack resistance is high; the adhesion strength and the consistency of the polystyrene modifying plastic to the polystyrene insulation board are high; the outer layer of an adhesion agent of the polystyrene insulation board can be effectively prevented from flaking off due to heat shrinking; the damage to an insulating layer can be reduced.
Description
technical field [0001] The invention relates to a chemical material, more specifically to a polystyrene modified plastic. Background technique [0002] Polystyrene insulation board is cheap and has good thermal insulation performance, and is widely used in building insulation systems. However, in recent years, fire accidents of thermal insulation materials and external wall thermal insulation systems have often occurred. There is no doubt that it is very important to emphasize the fire safety of the external wall insulation system. In the thermal insulation system widely used at present, polystyrene is the key to its fire safety performance. From the current technical level, it is difficult to achieve a high-standard polystyrene flame retardancy index, and simply increasing the amount of flame retardant added will pose a great threat to human life. By covering the surface of the polystyrene insulation board with a layer of fireproof interface agent, the fireproof perf...
