Problems solved by technology

[0004] The current production requirements of extruded board mostly require the board to be white, not only the appearance is more beautiful, but also the white board also shows that the board is more environmentally friendly. After coming out, it turns into a darker color. This kind of board will be mixed with a lot of substances harmful to the environment and human body, and it is impossible to identify the quality of the material from the appearance.

Abstract

The invention discloses a polystyrene thermal-insulation plastic extrusion plate similar to an EPS plate and a preparation method thereof. The polystyrene thermal-insulation plastic extrusion plate is prepared from the following components in parts by weight: 400-600 parts of polystyrene particles, 10-15 parts of benzoyl butyl ester peroxide, 8-12 parts of sodium dodecyl benzene sulfonate, 10-15 parts of benzoyl peroxide, 3-7 parts of 4-methyl sodium valerate, 0.5-1.2 parts of alkenyl succinate, 0.8-1.2 parts of zinc dialkyl dithiophosphate, 1-3 parts of ammonium benzoate, 1.2-1.4 parts of thiol benzimidazole and 4-6 parts of a foaming agent, wherein the polystyrene particles are mixed by polystyrene fresh materials, polystyrene reclaimed materials and polystyrene waste. By controlling the reaction temperature of the material and an adding proportion of a nucleating agent, the plastic extrusion plate is guaranteed to not get black; and meanwhile, the raw materials are not added with color master batches, so that the plate color is not deepened, and the appearance of the plate is similar to the that of the EPS plate; and the plate is white, clean and environmentally-friendly.

Description

technical field [0001] The invention relates to an extruded plastic board, in particular to an extruded plastic board similar to an EPS board. Background technique [0002] Existing external wall insulation materials on the market mainly use benzene modified board (EPS), polyurethane board and extruded board (XPS). Among them, benzene board is the cheapest, and the insulation effect is average, and it will absorb water and deform. After the insulation layer is completed, it needs to be Waterproof and other measures. Polyurethane is the best performance among existing insulation materials. Polyurethane is used as insulation material in refrigerators and cold storage. The thermal conductivity is far lower than that of benzene board and extruded board. Basically, half the thickness of polyurethane insulation layer can reach The insulation effect of the original thickness of benzene board and extruded board, but the price is much higher than that of benzene board and extruded b...
