Description

A kind of PP polyblend and preparation method thereof
Technical field
The application belongs to plastic alloy material field, particularly relates to a kind of PP polyblend and preparation method thereof.
Background technology
Polypropylene English name: be called for short: PP, is commonly called as: polypropylene (PP).Polypropylene is the representative of poly-alpha olefins, a kind of thermoplastic resin obtained by propylene polymerization, and according to the difference of initiator and polymerization technique, polypropylene can be divided into isotatic polypropylene and Atactic Polypropelene and syndiotactic polypropylene three kinds of configurations.Isotatic polypropylene easily forms crystal form, and degree of crystallinity is up to more than 95%, and molecular weight, between 8-15 ten thousand, gives its good heat resistanceheat resistant and good solubility-resistence; Atactic Polypropelene is at room temperature a kind of amorphous, micro-adhesive White waxy thing, and molecular weight is low, and at 3000-10000, structure irregularity lacks force of cohesion, applies less.
Polypropylene (PP) is one lighter in common plastics, its excellent electrical property, can be used as wet-heat resisting high-frequency insulation materials application.PP belongs to crystalline polymer, during melt condensation because of specific volume change greatly, degree of molecular orientation is high and present shrinking percentage (1.0%-1.5%) greatly.In the molten state, the effect reducing its viscosity with heating up is little for PP.Therefore in molding process, should to improve injection pressure and shearing rate, to improve the Forming Quality of goods.
PP in injection moulding machine machine barrel through preformed melted by heating.Injection moulding starts, and it is the high-voltage high-speed mold filling process under dynamic pressure effect that screw head generation injection pressure is full of this one-phase of die cavity to melt.Now the mobility status of high-temperature fusant in die cavity decides products surface quality and physicals to a great extent, and melt flow situation is by injection pressure and melt itself affect.When injection pressure is too low, it is slow that melt enters die cavity, that one deck melt being close to mould intracavity wall surface can decline and viscosity is increased solidify by Yin Wendu rapidly, and Hen Kuaixiang center is involved, make the flow passage of melt within very short time, become very narrow, largely reducing the melt flow entering die cavity, result makes product surface occur ripple, lack material, bubble.When injection pressure is too high, melt mold filling is too fast, near cast gate, enter die cavity with turbulence form, and generation free-jetting, mould intracavity gas has little time to discharge, so product surface presents the defects such as cloud and mist spot, article removal unrelieved stress is large, easily produces overlap and makes demoulding difficulty.Although high injection pressure can improve injection rate and obtain large shearing action in injection moulding process.Thus reduction melt viscosity, but say from physical significance, too high pressure can make melt viscosity increase, this is because along with the increase of pressure, the distance between molecular chain is compressed, and the changing of the relative positions between molecular chain is more difficult, and melt flow difficulty, viscosity also just increases.Therefore, should note holding high speed injection motding, the i.e. effect of high shear rate in the mold filling stage, and injection pressure should do not improved simply.Large to the wall thickness change of some top grades, to have thicker bead and muscle goods, should adopt multipole injection molding to control shearing rate.In actual production, general first furnishing low speed low pressure, makes melt steadily enter mould; Make melt close to being full of die cavity with the high speed and high pressure that two-stage is different again, and prevent eddy current; Finally press with in one-level low speed, avoid overflow edge to produce, to complete mold filling process smoothly.
After mold filling terminates, the quick flowing of PP melt stops, and cavity pressure starts to increase, and meanwhile injection pressure also increases sharply.When injection pressure reaches maximum value, cavity pressure does not reach maximum value, and the extreme value of cavity pressure will lag behind maximum injection pressure for some time, and the flow process of melt is density process around here.Within the time that this section is very short, melt will be full of each several part gap of die cavity, itself will be compressed, melt flow is very little, temperature variation is also not obvious, at this moment injection pressure is also delivered to cavity surface by melt, produces cavity pressure (complexity of transmission depends on the mobility of melt).The maximum value that the maximum value of injection pressure determines cavity pressure and can reach in injection moulding density process can be said.Along with injection pressure improves rapidly, cavity pressure also reaches maximum value, produces very large kinetic energy impact, Clamping Device of Injection Moulding Machine and mold system are deformed in die cavity, and micro-distending mould.Under normal deformation condition, mould fine motion distending has degassing, therefore with higher pressure injection-moulded, will can compress melt like this, the viscous state melt being successively full of die cavity from different directions can be made again to be melt into an entirety.But injection pressure can not be excessive, otherwise can cause goods sticking to mould, after depanning, goods have overflow edge, size swells, and affect Forming Quality.
The pressure of packing stage PP melt in die cavity and specific volume constantly change (specific volume of PP is changed to 16%), and are maintained to till cast gate closes.The principal element affecting pressure maintaining period is pressure.Dwell pressure can make melt in die cavity obtain sufficient pressure and feed supplement all the time before solidifying completely, thus occurs the flowing of melt, and feature is that flow velocity is slow, and reason is that melt shrinks because of cooling.Because when PP melt is reduced to die temperature from injection temperature, in melt macromole can relax, crystallization, volumetric shrinkage is comparatively large, so must overcome cast gate resistance with enough large dwell pressure to carry out feed supplement.The increase of dwell pressure also can make the density of goods increase, and the free intensity of variation of the product surface after depanning reduces, and rugosity is rented on the surface obtained close to die face, reduces molding shrinkage, promotes the fusion between melt each several part, improve the mechanical property of goods.The 60-70% of general dwell pressure the highest desirable injection pressure value, for improving product molding quality, also can adopt segmentation pressurize to carry out pressure-controlling.
Polyblend utilizes the method for physical blending or chemical graft and a class novel material of the high-performance obtained, functionalization, customizations.Polyblend product can be widely used in the fields such as automobile, electronics, precision instrument, office equipment, wrapping material, material of construction.It can improve or improve the performance of existing plastics and reduce costs, and has become one of kind enlivened the most in plastics industry, has increased very rapid.China's plastic industry will be got a clear understanding of the situation, and finds gap accurately, seizes the opportunity, and strengthens input in science and technology, accelerates development Plastics Industry, world development level of emulating.PC/ABS as the maximum commercial polymerization thing alloy of sales volume in the world, in recent years all with about 10% demand speed increment.PC/ABS improves mobility than PC, improves processing characteristics, decreases the susceptibility of goods counter stress, is thus widely used in automotive trim, exterior trim, the high strength such as car light, high heat-resisting part.Along with the raising of people's environmental consciousness, the appearance in succession of the recyclable regulation of the environmental protection such as automobile industry ELV, starting material manufacturer also constantly provides new solution.What the leader as engineering plastics industry was in good time is proposed PC/ABS alloy series material of new generation, it mainly includes the PC/ABS of stability to hydrolysis resistance, for exempting from the ultralow gloss PC/ABS spraying interior trim, chemicals-resistant is excellent is not easily waited the series product such as the chemically-resistant solvent PC/ABS corroded by paint.And popularizing along with humanity concept, and the formation of novel harmonious society, design PP polyblend that a kind of intensity is high, high temperature resistant, elongation at break is high and preparation method thereof and be very important.
