Embodiment 1

[0017] Using melamine as a carrier, weigh 20 parts of aluminum hydroxide, 10 parts of iron oxide red, 3 parts of n-pentane, 15 parts of expanded graphite, 5 parts of silica sol, and 2 parts of γ-aminopropyl triethoxy silane and 2 parts zirconium dioxide. When preparing the flame-retardant polystyrene board, add the above-mentioned inorganic materials into the mixer in sequence, and stir evenly for 6 minutes, so that the flame retardant becomes viscous and can wrap the polystyrene particles.

[0018] After adding 10% curing agent to the flame retardant, mix it evenly with the pre-expanded polystyrene masterbatch particles according to the weight ratio of 1:50, so that the flame retardant slurry is wrapped in the pre-expanded polystyrene masterbatch The surface of the material particles is dried at 65~75°C using fluidized bed drying equipment; then the wrapped particles are filled into the preheated sheet forming machine, and the mold is heated by steam at 95~110°C to keep the p...

[0020] Using melamine as a carrier, weigh 15 parts of aluminum hydroxide, 5 parts of iron oxide red, 2 parts of isopentane, 10 parts of expanded graphite, 3 parts of silica sol, 1 part of titanate coupling agent and 1 part by weight. parts zirconium dioxide.

[0021] When preparing the flame-retardant polystyrene board, add the above-mentioned inorganic materials into the mixer in sequence, and stir evenly for 5 minutes, so that the flame retardant becomes viscous and can wrap the polystyrene particles.

[0022] After adding 10% curing agent to the flame retardant, mix it evenly with the pre-expanded polystyrene masterbatch particles according to the weight ratio of 1:40, so that the flame retardant slurry is wrapped in the pre-expanded polystyrene masterbatch The surface of the material particles is dried at 65~75°C using fluidized bed drying equipment; then the wrapped particles are filled into the preheated sheet forming machine, and the mold is heated by steam at 95~110°C ...

Embodiment 3

[0024] Using the epoxy resin diluted with 5% pure water as the carrier, weigh 25 parts of aluminum hydroxide, 15 parts of iron oxide red, 4 parts of isopentane, 20 parts of expanded graphite, 8 parts of silica sol 3 Parts of γ-aminopropyltriethoxysilane and 3 parts of zirconium dioxide.

[0025] When preparing the flame-retardant polystyrene board, add the above-mentioned inorganic materials into the mixer in sequence, and stir evenly for 7 minutes, so that the flame retardant becomes viscous and can wrap the polystyrene particles.

[0026] After adding 10% curing agent to the flame retardant, mix it evenly with the pre-expanded polystyrene masterbatch particles according to the weight ratio of 1:30, so that the flame retardant slurry is wrapped in the pre-expanded polystyrene masterbatch The surface of the material particles is dried at 65~75°C using fluidized bed drying equipment; then the wrapped particles are filled into the preheated sheet forming machine, and the mold is...

Abstract

The invention provides an inorganic flame retardant for wrapping polystyrene granules, solving the problem of the conventional flame retardant polystyrene plate that the environment is easily polluted due to the added brominated flame retardant. The inorganic flame retardant for wrapping the polystyrene granules is characterized by comprising the following components in parts by weight: 15 to 25 parts of aluminium hydroxide, 5 to 15 parts of iron oxide red, 2 to 4 parts of foaming agent, 10 to 20 parts of expanded graphite, 3 to 8 parts of inorganic glue, 1 to 3 parts of coupling reagent, and 1 to 3 parts of zirconium dioxide, which are loaded on a resin carrier. According to the inorganic flame retardant, all the components are inorganic components, and thus less pollution is brought to the environment; the addition amount of the inorganic flame retardant is small, and 1 to 10wt% of the inorganic flame retardant is always added and can efficiently retard the flame, and therefore the fireproof performance of the polystyrene plate can be increased to A2 level.

Description

technical field [0001] The invention relates to the technical field of polystyrene plates, in particular to an inorganic flame retardant for wrapping polystyrene particles. Background technique [0002] Polystyrene board - also known as foam board, is made of expandable polystyrene beads containing volatile liquid foaming agent. After heating and pre-expanding, it is a white object that is heated and formed in a mold. It has fine closed cells. Structural features, mainly used for building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle, ship insulation, floor heating, decoration and engraving, etc. are very widely used. [0003] However, this type of material is flammable and has the possibility of causing a fire. When organic thermal insulation materials burn, the fire spreads rapidly, accompanied by a large amount of poisonous gas and smoke, which brings serious difficulties to fire fighting and rescue work, and easily causes ca...
