Description
Technical field
The present invention relates to a kind of PVC section bar formula and working method thereof.
Background technology
PVC plastic material formula is mainly made up of PVC resin and auxiliary agent, and wherein auxiliary agent is divided into again by function: thermo-stabilizer, lubricant, modifier, impact modifying agent, weighting agent, antiager, tinting material etc.The resin of producing PVC plastic material is polyvinyl chloride (PVC) RESINS (PVC), and polyvinyl chloride is the polymkeric substance being formed by polymerization of vinyl choride monomer, and output is only second to PE, occupies second.PVC resin is because the difference of the dispersion agent in polymerization can be divided into two kinds of loose type (XS) and tight types (XI).Loose type particle diameter is 0.1-0.2mm, surface imperfection, and porous, is cotton spherical, easily absorbs softening agent, and tight type particle diameter is below 0.1mm, and rule of surface is solid, is table tennis spherical, is difficult for absorbing softening agent, uses at present the more of loose type.PVC can be divided into again regular grade (poisonous PVC) and sanitation-grade (nontoxic PVC).Sanitation-grade requires vinylchlorid (VC) content lower than lOXl0-6, can be used for food and medical science.Synthesis technique difference, PVC can be divided into again suspension method PVC and emulsion method PVC.Stipulate according to standard GB/T/T5761-93 " the universal polyvinyl chloride (PVC) RESINS inspecting standard of suspension method ", suspension method PVC is divided into PVC-SGl to several resins of PVC-SG8, wherein numeral is less, the polymerization degree is larger, molecular weight is also larger, intensity is higher, but melt-flow is more difficult, processes also more difficult.When concrete selection, while doing soft goods, generally use PVC-SGl, PVC-SG2, PVC-SG3 type, need to add a large amount of softening agent of people.For example polychloroethylene film uses SG-2 resin, adds the softening agent of 50 ~ 80 parts.And processing is when boardy product, generally do not add or seldom amount add softening agent, so by PVC-SG4, VC-SG5, PVC-SG6, PVC-SG7, PVC-SG8 type.PVC hard tube material uses SG-4 resin, as plastic door-window section bar uses SG-5 resin, hard transparent sheet uses SG-6 resin, hard foamed section bar to use SG-7, SG-8 resin.
PVC section bar is to be added after various functional agents by polyvinyl chloride resin, through industry and the life PVC product of high temperature extrusion moulding.Can be divided into hard and soft two kinds by performance.Hard PVC section bar is used for building aspect, as made PVC door and window, PVC floor, pvc pipe material etc.; Flexible PVC section bar is for PVC flexible pipe, feeder cable etc.
