Embodiment 1

[0030] Select industrial solid waste - stone coal, and activate it by calcining at 800°C for 4 hours to obtain activated sintered material, then grind the obtained activated sintered material through a ball mill, and then sieve out the powder with a particle size of less than 200 mesh with a fine mesh sieve, and mix the obtained powder with Antimony trioxide is uniformly mixed according to the mass ratio of 1:2 to obtain the stone coal composite PVC flame retardant of the present invention.

Embodiment 2

[0032] Select industrial solid waste - stone coal, and activate it by calcining at 700°C for 6 hours to obtain activated sintered material, then grind the obtained activated sintered material through a ball mill, and then sieve out the powder with a particle size of less than 200 mesh with a fine mesh sieve, and mix the obtained powder with Antimony trioxide is evenly mixed according to the mass ratio of 1:3 to obtain the stone coal composite PVC flame retardant of the present invention.

Embodiment 3

[0034] Select industrial solid waste - stone coal, and activate it by calcining at 750°C for 5 hours to obtain activated sintered material, then grind the obtained activated sintered material through a ball mill, and then sieve out the powder with a particle size of less than 200 mesh with a fine mesh sieve, and mix the obtained powder with Antimony trioxide is evenly mixed according to the mass ratio of 1:3 to obtain the stone coal composite PVC flame retardant of the present invention.

Abstract

The invention discloses a stone coal compound type PVC flame retardant. The stone coal compound type PVC flame retardant is formed by compounding mixture and antimony trioxide, wherein the mixture is obtained by conducting calcination activation and grinding on stone coal, and the mass ratio of the stone coal subjected to activation treatment to antimony trioxide is 1:(2-5). A stone coal compound type PVC flame retardant material is prepared from, by mass, 6-11 parts of stone coal compound type PVC flame retardant, 100 parts of PVC resin, 30 parts of plasticizer, 4 parts of stabilizer and 0.6 part of lubricating agent. When the flame retardant is applied to the PVC flame retardant material, the smoke amount and produced toxic gas or corrosive gas are less during the combustion process, and the flame retardant is an environment friendly product; the flame retardant and the flame retardant material are high in flame retardant efficiency and thermal stability, and when the flame retardant is used for the flame retardant material, the flame retardant itself cannot be easily decomposed when the material is processed.

Description

technical field [0001] The invention relates to the technical field of flame retardants, in particular to a stone coal composite PVC flame retardant, a flame retardant material and a preparation method thereof. Background technique [0002] The flame retardants currently used in PVC mainly include halogen-antimony synergistic flame retardants, phosphate ester flame retardants, inorganic flame retardants, etc. Among them, the antimony compound in the halogen-antimony synergistic flame retardant is mainly antimony trioxide. Using antimony trioxide alone not only enhances the flame retardant effect, but also increases the smoke generation, and the price is relatively high. [0003] In the prior art, some people have used zinc borate to partially replace antimony trioxide, and achieved a certain effect of flame retardancy and smoke suppression. Shi Xichang, Lattimer, R.P., Tu Hongbin, Lin Anliang and others found that transition metal oxides and some other metal oxides in inorg...
