Embodiment
In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention provides one containing antimony flame-proof composite material, comprises following composition composition polyvinyl chloride (PVC) RESINS 48～58wt%, softening agent 20～25wt%, weighting agent 12～18wt%, without antimony fire retardant material 3～8wt%, stablizer 2～4wt%.
Polyvinyl chloride (PVC) RESINS, except the homopolymer of vinylchlorid is polyvinyl chloride, can also enumerate the multipolymer of vinylchlorid and other copolymerisable monomer and their mixture.As polyvinyl chloride (PVC) RESINS, can use mean polymerisation degree is 1000～2500 material, the polyvinyl chloride (PVC) RESINS that preferred degree of polymerization of the present invention is 1300.
Softening agent is for giving polyvinyl chloride (PVC) RESINS with flexibility, and makes the additive of handling ease.In the present embodiment, use trioctyl trimellitate as softening agent.By this structure, can improve the thermotolerance of poly (vinyl chloride) resin composition, Simultaneous Stabilization electrical insulating property.In addition, can also in above-mentioned trimellitate, suitable blend use other types softening agent.Preferably 20～25wt% of the content of softening agent, when less than 20 quality %, the winter hardiness of resin combination is poor, and on the other hand, in the time exceeding 25wt%, the combustiblecomponents in resin combination increases, and is difficult to obtain flame retardant effect.
In poly (vinyl chloride) resin composition, except above-mentioned softening agent, fire retardant, stablizer, weighting agent, can also suitably add other additive etc.
Particularly, described in the present embodiment, do not comprise following composition composition containing antimony flame-proof composite material: polyvinyl chloride (PVC) RESINS 48～58wt%, trioctyl trimellitate 20～25wt%, nano-calcium carbonate 12～18wt%, without antimony fire retardant material 3～8wt%, calcium-zinc composite stabilizing agent 2～4wt%, epoxy soybean oil 1～2wt%, polyethylene wax 0～0.5wt%, other auxiliary agent 1～3wt%.
