Embodiment 1

[0008] Preparation of PP flame-retardant plastic: 150-155 parts by mass of PP, 5-10 parts by mass of brucite, 10-20 parts by mass of triphosphite, 10-15 parts by mass of nano-montmorillonite, 10-13 parts by mass of Iron, 8-11 parts of styrene, 14-16 parts of alkylbenzene sulfonate, 2-3 parts of copper oxalate, 7-9 parts by mass of phthalic anhydride, 10-15 parts by mass of melamine cyanurate, 10- 15 parts by mass of zinc oxide, 10 parts by mass of dicyandiamide and 5-8 parts by mass of organotin are mixed and put into a mixer, stirred evenly, put into a twin-screw extruder for plasticization and granulation, and the temperature is 195°C, 200°C, 205°C ℃, 210℃, 205℃, the screw speed is 70r / min; the pellets are processed into splines by injection molding, and the temperature is 170℃, 185℃, 195℃, 190℃. The main properties of the material prepared in this example are as follows: tensile strength MPa (GB / T1040-2006): 35-36, % elongation at break (GB / T 1040-2006 ): 11-13; impact ...

Abstract

The invention discloses polypropylene (PP) flame-retardant plastic. The PP flame-retardant plastic comprises, by weight, 150-155 parts of PP, 5-10 parts of brucite, 10-20 parts of triguaiacyl phosphite, 10-15 parts of nano-montmorillonite, 10-13 parts of ferrocene, 8-11 parts of styrene, 14-16 parts of alkylbenzene sulfonate, 2-3 parts of copper oxalate, 7-9 parts of phthalic anhydride, 10-15 parts of melamine cyanurate, 10-15 parts of zinc oxide, 10 parts of dicyandiamide and 5-8 parts of organic tin. The PP flame-retardant plastic has good fire resistance and a small amount of the PP flame-retardant plastic can produce obvious flame retardation. The PP flame-retardant plastic has good compatibility with resins so that the PP flame-retardant plastic is not transferred, separated and extracted in a plastic product. In plastic, the PP flame-retardant plastic can be dispersed uniformly and has good weatherability, persistence and long-term flame resistance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a PP 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 materials,...
