Expandable polystyrene anti-aging flame-retardant plate

Abstract

The invention discloses an expandable polystyrene anti-aging flame-retardant plate and relates to the field of preparation of expandable polystyrene. The expandable polystyrene anti-aging flame-retardant plate comprises well cured expandable polystyrene particles, flame retardant slurry and anti-aging agent slurry, wherein the weight part ratio of the expandable polystyrene particles to the flame retardant slurry to the anti-aging agent slurry is (9-10):1:(0.5-1); the flame retardant slurry comprises the following components in parts by weight: 4-5 parts of ammonium phosphate, 0.4-0.5 part of antimony trioxide, 2-3 parts of aluminium chloride, 0.5-1 part of zinc borate, 4-5 parts of magnesium chloride, 3-4 parts of citric acid and 7-8 parts of deionized water; and the anti-aging agent slurry comprises the following components in parts by weight: 4-5 parts of 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline, 2-2.5 parts of N-cyclohexyl-N'-phenyl-P-phenylenediamine, 1-1.5 parts of 4-benzoyloxy-2,2,6,6-tetramethyl piperidine, 2-3 parts of 2,4-dihydroxy benzophenone, 1-2 parts of resorcinol monobenzoate and 10-11 parts of an ethanol solution. By adopting the technical scheme, the fireproof performance of the expandable polystyrene can be enhanced, the service life of the expandable polystyrene is prolonged, and then the generation of waste and old plates is reduced and the environment is protected.

Description

technical field [0001] The invention belongs to the field of expandable polystyrene preparation, in particular to an expandable polystyrene anti-aging flame retardant board. Background technique [0002] Expandable polystyrene (EPS) can be made into foam products of different densities and shapes through pre-expanding, curing, molding, drying and cutting, and can also produce foam boards of various thicknesses; it is widely used in construction, Insulation, packaging, refrigeration, daily necessities, industrial casting and other fields; it can also be used in exhibition venues, commodity cabinets, advertising signs and toy manufacturing. After heated and foamed, expandable polystyrene contains 3 to 6 million independent airtight cells per cubic meter, and the contained air volume is more than 98%, and the density can be as low as 10 to 30kg / m3, so it can be expanded. Polystyrene is currently the lightest packaging material. Under high load conditions, this material will be...

Problems solved by technology

[0003] Although expandable polystyrene has certain fireproof and anti-aging functions, in actual use, these functions are difficult to exert, which leads to a greatly shortened service life of expandable polystyrene, and the shortened service life will not only increase the The use cost of expanded polystyrene will also produce a large amount of waste materials, which are difficult to decompose and recycle in the natural environment; if things go on like this, our environment will also receive a huge threat
