Embodiment 1

[0008] Preparation of HIPS flame-retardant plastic: 105-110 parts by mass of HIPS, 10-15 parts by mass of nano silicon dioxide, 10-15 parts by mass of melamine cyanurate, 10-15 parts by mass of glass fiber, 10-12 parts by mass of antimony Natrate, 8-11 parts of styrene, 14-16 parts of alkylbenzene sulfonate, 2-3 parts of copper oxalate, 10-20 parts by mass of triphenyl thiophosphate and 10 parts by mass of zirconia are mixed into a mixer, After mixing evenly, put it into a banbury mixer for banbury mixing, the banbury temperature is 140-145°C, and the rotation speed is 900-950rpm; then the mixture after banbury mixing is granulated by a granulator to obtain granules, and the granules are cooled in a water tank, and then Dry at room temperature; the main properties of the material prepared in this example are as follows: tensile strength MPa (GB / T1040-2006): 35-38, % elongation at break (GB / T 1040-2006): 11-12 ;Impact strength kJ / m 2 (GB / T1043-2008): 5.0; bending strength ...

Abstract

The invention discloses high impact polystyrene (HIPS) flame-retardant plastic. The HIPS flame-retardant plastic comprises, by weight, 105-110 parts of HIPS, 10-15 parts of nano-silica, 10-15 parts of melamine cyanurate, 10-15 parts of glass fibers, 10-12 parts of sodium antimonate, 8-11 parts of styrene, 14-16 parts of alkylbenzene sulfonate, 2-3 parts of copper oxalate, 10-20 parts of triphenyl thiophosphate and 10 parts of zirconia. The HIPS flame-retardant plastic has good fire resistance and a small amount of the HIPS flame-retardant plastic can produce obvious flame retardation effects. Mechanical strength of the HIPS flame-retardant plastic is not influenced and especially, a heat deflection temperature, a kinetic temperature and electric insulation properties of a plastic product are not influenced. The HIPS flame-retardant plastic can be uniformly dispersed and has good weatherability, long action time and long-term flame resistance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a HIPS flame-retardant plastic. technical background [0002] With the continuous development of science and technology and economy, daily necessities made of plastics play an increasingly important role in daily life. However, plastics are easy to burn, and the burning speed is fast, and a large amount of toxic gases will be produced. With the wide application of plastics in construction, furniture, transportation, aviation, aerospace, electrical appliances, etc., at the same time, there are countless fires caused by plastic products. The fire situation is not optimistic. Some major fire accidents occur frequently, and many of them are nylon mesh, Flammable materials such as polyurethane foam burn rapidly, causing death, injury and property damage. The vast majority of plastics are flammable substances, but in plastic construction materials, transportation material...
