Embodiment 1

[0045] Firstly, fill the collected waste and old combustible polystyrene foam into the pulverizer and crush it into polystyrene foam particles with a particle size of 1 mm to 2 mm, and mix 300 g of waste polystyrene foam particles with 700 g of ordinary combustible polystyrene foam Ethylene foam plastic particles are mixed and put into the mixer through a conveyor; then add 20g of inorganic flame retardant, 3g of water-soluble adhesive, 2g of inorganic dispersant, 15g of strength enhancer, and 1g of pH regulator , water 30g, inorganic antibacterial agent 4g, inorganic foaming agent 1g, after mixing the above ingredients for 15 to 25 minutes, a non-combustible waste polystyrene foam raw material is produced; then the raw material is put into the mold, and the hydraulic press According to the specifications of 450mm×450mm×50mm, it is pressed into shape, and it is the finished product after demoulding;

[0046] The inorganic flame retardant is selected from sodium hydroxide, alum...

Abstract

The invention relates to fireproof flame-retarding polystyrene foam which is technically characterized in that an inorganic flame retardant, a water-soluble adhesive, an inorganic dispersing agent, a strength enhancer, water and a foaming agent are added into polystyrene foam plastic granules, extracted from waste polystyrene foam plastics, and ordinary polystyrene foam plastic granules. The invention further provides a production method of the fireproof flame-retarding polystyrene foam. The fireproof flame-retarding polystyrene foam disclosed by the invention has the physical and chemical properties of light weight, cushioning, heat insulation, chemical resistance and the like, and further has the characteristics of simple process, low cost, wide application range, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of producing flame-retardant and heat-retaining building materials from organic chemical raw materials, in particular to a fire-proof and flame-retardant polystyrene foam and a production method thereof. Background technique [0002] Generally, polystyrene foam is a lightweight (specific gravity: 0.03) material that is 30 or 50 times larger than its own volume and accounts for 98% of the air volume, which is produced by foaming and expanding with propane gas or pentane gas. Economical industrial materials, and this material is still being developed and applied today. Polystyrene foam is characterized by excellent heat preservation, heat insulation, cushioning, and light weight. It is mainly used in heat insulation materials for buildings, hygienic packaging for agricultural and aquatic products, cushioning packaging for home appliances, and heat insulation for boilers. Uses, disposable tableware, ships, avi...
