The polyvinyl chloride plastic is characterized in that the polyvinyl chloride plastic comprises following raw materials by weight: 80-90 parts of polyvinyl chloride, 30-60 parts of flame-retardant plastic additives, 5-6 parts of barium stearate, 2-4 parts of calcium stearate, 4-5 parts of a brominated flame retardant and 10-15 parts of an auxiliary agent; and the flame-retardant plastic additives comprise following components by weight: 25-30 parts of antimonous oxide, 15-20 parts of zinc borate, 60-80 parts of phosphotriester, 10-20 parts of tetrabromobutane and 1-5 parts of chloropropylene oxide.
Description
Technical field
The present invention relates to a kind of plastics, particularly a kind of high flame retardant igelite.
Background technology
Because the application of plastics is increasingly extensive, as industries such as electronics, military project, daily use chemicals, these industries are quite high to fire-retardant requirement, generally all require to add fire retardant to reach fire-retardant object in plastic production process, the current single flame-retardant additives such as hibbsite, antimonous oxide that generally all add in plastics-production process, these single flame-retardant additives add and excessively in some performance, can exert an influence to finished product, add very few again less than flame retardant effect, so the synergistic system of fire retardant becomes the important topic of the sector technician further investigation.
Polyvinyl chloride is the thermoplastic resin being polymerized under initiator effect by vinylchlorid.Because polyvinyl chloride has the advantages such as chemical proofing is high, electrical insulation capability good, physical and chemical performance is stable, cheap, it is widely used in each fields such as industry, agricultural, traffic, building, communication and health care.But pure polyvinyl chloride has certain defect at aspects such as physical strength and flame retardant propertiess, limited its use.In order to improve the fire-retardant and mechanical property of polyvinyl chloride, conventionally also need to add other component, as fire retardant, filler etc.In order to meet the requirement of some mechanical property and high flame retardant, the addition of fire retardant and filler is generally all very large, the component of these interpolations conventionally all can not be well compatible with polyvinyl chloride (PVC) RESINS, on the other hand due to not rationally performance of the mutual synergistic effect between these additives, need a large amount of additives just can reach the effect needing, thereby cause the processing flowability of final polyvinyl chloride composite materials greatly to reduce.Prior art can be found out, in PVC modified process, improves its flame retardant resistance and improves the scheme that its mobility is mutual restraint, if flame retardant resistance improvement, mobility reduces, if mobility improvement, flame retardant resistance reduction.
