Background technology
Soft-hard coextrusion frame is used for carrying out bound edge to product.Application number be 201210090016.7 Chinese patent provide a kind of wood-plastic co-extrusion door-window section bar, this profile structure as shown in Figure 1, be the wood-plastic co-extrusion section bar be integrally formed by PVC-U plastic material and Wood-plastic profiles, synchronously inputted the product moulding mould of a composite co-extruding respectively by two kinds of different extruders.This utility model only relates to the co-extruding mould of two kinds of profile shapes, and major part is for door and window, and the bound edge for product relates to less.As come product bound edge with above-mentioned wood-plastic co-extrusion section bar, its Wood-plastic profiles extensibility is poor, and it is not high to be used for the packaging ceramic product goodness of fit, easily occurs that section bar ruptures, and needs better shock-absorbing capacity for the packaging of the friable products such as pottery, porcelain, glass.
Utility model content
The utility model is in order to solve the problem of prior art, provide a kind of PVC co-extrusion frame, the groove part of this section bar is the edge being configured to pack fragile article by soft rim section bar, makes it to have good shock resistance, crash resistance and stronger resiliency, to solve the demand of people.
The PVC co-extrusion frame that the utility model provides: the plastic frame section bar comprising the extruded hard PVC of composite co-extruding and flexible PVC one, wherein soft pvc plastic section bar draw-in groove both sides adopt arc structure.This project organization is conducive to described plastic co-extrusion shape of peripheral frame and is used for packing laminating degree and the sealing that the friable product edges such as pottery, glass can increase its edge, soft pvc plastic shape of peripheral frame described in the utility model is better than hard PVC shape of peripheral frame for the buffering anti-seismic performance of friable product, and the characteristic of hard PVC and flexible PVC is combined with each other by the plastic co-extrusion shape of peripheral frame of hard outside soft inside especially, described plastic co-extrusion shape of peripheral frame is optimized more in the performance of packaging pottery, porcelain tool, glass edge frame.
Further improvement, described hard PVC section bar adopts hollow chamber's structure, and the inside of hard PVC section bar is separated into several airtight or little spaces of semi-hermetic.This project organization not only can save material to hard PVC, saves green energy resource, and is conducive to the man-hour of the cutting action of plastic co-extrusion shape of peripheral frame in later stage use procedure described in saving.
Further improvement, the outer surface of described hard PVC section bar has two grooves of uniform size.This project organization makes to be placed in machine or other products with the friable product that this outer rim is packed, and the groove of outer surface can increase the steadiness of its friable product.
Further improvement, the end of soft pvc plastic section bar draw-in groove both sides arc structure is provided with the solid roundlet of two flexible PVCs.This project organization is conducive to described plastic co-extrusion shape of peripheral frame, and to be used for surface of package irregular, concavo-convex uneven friable product, increases frictional force to friable product edge, improves and grabs gravitation, make the laminating degree at described plastic co-extrusion shape of peripheral frame and fragile article edge tightr, not easily drop.
Its preparation method of PVC co-extrusion frame, comprises the following steps:
1) raw material of hard PVC and flexible PVC, auxiliary material are carried out sending into hard PVC extruder and flexible PVC extruder again after drying processes through drier, order of addition for first by hard PVC resin and flexible PVC resin in mass ratio 3:1 start the mixed machine of heat after adding high-speed mixer respectively, then add auxiliary material; Described auxiliary material comprises the anti-impact modifier, stabilizing agent, lubricant, colouring agent and the filler that add successively, and in auxiliary material adition process, colouring agent adds rear kneading and adds filler again in 3 minutes.
2) after 8-10min mediates, when temperature reaches 100-120 DEG C, then the material synchronously extruded in proportion by two plastic extruders is respectively input in the product moulding mould of a composite co-extruding and carries out extrusion molding; The entering respectively through feeding section, fusing section, homogenizing zone in extruder of hard PVC and flexible PVC in extrusion molding, the temperature of three sections is set as: hard PVC Solid Conveying and Melting go temperature control 100-140 DEG C, material plasticizing district temperature control 170-190 DEG C, delivery area temperature controls at 160-180 DEG C; Flexible PVC feeding section temperature control 110-130 DEG C, physics plasticizing zone temperature control 140-160 DEG C, delivery area temperature controls at 160-170 DEG C, carries out shaping at 170-180 DEG C of temperature.
3) enter after extrusion molding in vacuum forming mould and carry out cooling and shaping, vacuum setting 20.0 ~ 53.3kPa, water temperature is below 15-45 DEG C.Draw tubing equably through traction again, hauling speed controls the 1%-3% at fast extruded velocity, then by cut and conventional subsequent processing operations is made.
The utility model beneficial effect is:
1, the process conditions of hard and soft pvc plastic composite co-extruding are next time shaping, its structure is simple, hard outside soft inside, not only increases the resistance to compression shock resistance index of plastic co-extrusion shape of peripheral frame, makes again appearance reach design concept that is brief, fashion.
2, the plastic material needed for co-extrusion frame, selects that mechanical property is good, the PVC plastic composite co-extruding forming process of the strong and light quality of corrosion resistance.
3, be that the soft and hard plastic section bar of carrier shapes technique perfect adaptation separately with PVC, apply section bar composite co-extruding forming process of the same race and inlay group technology, having filled up the blank in co-extrusion frame section bar complex technique of the same race field.
