Embodiment 1

[0008] Preparation of PVC flame-retardant plastic: 180-185 parts by mass of PVC, 10-15 parts by mass of talcum powder, 10-15 parts by mass of tetraantimony hexoxide, 10-15 parts by mass of trityl phosphate, 10-20 parts by mass of Sanya Phosphate ester, 10-15 parts by mass of nano-montmorillonite, 10-14 parts of alkylbenzenesulfonate, 5-9 parts of dimethylsiloxane, 2-3 parts of copper oxalate, 10-15 parts by mass of zinc oxide, Mix 10 parts by mass of dicyandiamide, 5-8 parts by mass of organotin, and 10-15 parts by mass of stearic acid ester into a blender, stir evenly and put it into a banbury mixer for banburying. The banburying temperature is 190-195°C and the speed is 900 -950rpm; then the mixture after banburying is granulated by a granulator to obtain granules, the granules are put into a water tank for cooling, and then dried at normal temperature; the main properties of the material prepared in this embodiment are as follows: tensile strength MPa ( GB / T1040-2006): 39,...

Abstract

The invention discloses a flame-retardant PVC plastic. The flame-retardant PVC plastic PVC plastic comprises the following components in parts by weight: 180-185 parts of PVC, 10-15 parts of talcum powder, 10-15 parts of tetraantimony hexoxide, 10-15 parts of triphenylmethyl phosphate, 10-20 parts of triphosphite, 10-15 parts of nano montmorillonite, 10-14 parts of alkyl benzene sulfonate, 5-9 parts of dimethyl siloxane, 2-3 parts of cupric oxalate, 10-15 parts of zinc oxide, 10 parts of dicyandiamide, 5-8 parts of organic tin and 10-15 parts of hard acid ester. The flame-retardant PVC plastic has a good flame-retardant function; an obvious flame-retardant function can be performed when a very small amount of flame-retardant PVC plastic is used. The flame-retardant PVC plastic does not affect the mechanical strength of a plastic product and particularly does not lower the thermal deformation temperature, mechanical temperature and electric insulation property of the plastic product. The flame-retardant PS plastic does not decompose and react with other materials during the processing of high-temperature fusing forming and thermal forming.

Description

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