Problems solved by technology

[0003] In actual use, the fireproof effect of expandable polystyrene is not ideal, so manufacturers will add a little flame retardant to expandable polystyrene to improve its fireproof effect; at present, most manufacturers produce expandable polystyrene The expanded polystyrene fireproof board is to directly apply a layer of flame retardant on the surface of the fireproof board; this method not only makes it difficult to mix the flame retardant and expandable polystyrene; Burning effect is also lower

Embodiment 1

[0015] Example 1: An expandable polystyrene fireproof board, the fireproof board is pre-expanded by steam from expandable polystyrene raw material particles, and the internal flame retardant and the cured expandable polystyrene The granules are mixed evenly according to the weight ratio of 46:10, dried, then injected with steam, then put into the drying room for drying, and after cooling, apply external flame retardant on the surface of the board according to the following steps.

[0016] (1) Preliminary equipment maintenance and inspection:

[0017] A) Check whether the ultrasonic mixer is normal; pour clean water into the ultrasonic mixing chamber, then turn on the ultrasonic generator for 12 minutes, then observe whether the dirt or impurities adhering to the mixing chamber are removed; if it is cleared, replace it immediately or repair;

[0018] B) Remove impurities or dust in the mixing chamber of the ultrasonic mixer; after all the dirt or impurities have been separated...

Abstract

The invention discloses an expandable polystyrene fireproof plate, and relates to the field of preparation of expandable polystyrene. The expandable polystyrene fireproof plate comprises the following raw materials in part by weight: 46-61 parts of internally used flame retardant, 64-98 parts of externally used flame retardant and 10 parts of cured expandable polystyrene particles, and is characterized in that the internally used flame retardant comprises the following ingredients in part by weight: 10-11 parts of ammonium phosphate, 0.8-1 part of antimonous oxide, 4-5 parts of aluminum chloride, 1-2 parts of zinc borate, 8-9 parts of magnesium chloride, 12-13 parts of citric acid and 15-21 parts of deionized water; and the externally used flame retardant comprises the following ingredients in part by weight: 20-25 parts of micro-encapsulation red phosphorus, 10-15 parts of aluminum hydroxide, 6-8 parts of expansible graphite, 10-15 parts of magnesium hydrate and 0.5-1 part of auxiliaries. By the scheme, the fireproof performance of the expandable polystyrene is fulfilled, and the original low heat conduction and the original high waterproofness of the expandable polystyrene are maintained.

Description

technical field [0001] The invention belongs to the field of expandable polystyrene preparation, and in particular relates to an expandable polystyrene fireproof 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 production, etc. 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 EPS is the current The lightest packaging material, when the load is high, this material will be bent, and when it is shaken or fa...
