The present invention implement time,
The first step: the waste and old section bar removed is carried out, smashes, pulverizing；
Second step: by PVC:100kg, nanometer calcium: 12.5kg, CPE:12.5kg, rutile titanium white lead: 4.5kg, ACR:1.5kg, Stearic acid: 0.1kg, PE wax: 0.1kg, calcium zinc stabilizer: 5kg, antioxidant: 0.5kg, fire retardant: 5.5kg, brightening agent: 30g, Ultramarine: 8g adds in extruder together, extrudes under the effect of 47 twin screw of extruder, forms top layer slip, passes through First spiral the 27, second spiral the 28, the 3rd spiral the 29, the 4th spiral the 30, the 5th spiral the 31, the 6th spiral 32 and the 7th spiral 33 Extruding so that the density of slip out meets requirement；The total length of screw rod and the length of 48 screw rods are the same, remain as 990mm, only modifies to diameter so that a diameter of 47mm in the less one end of screw rod, and bigger one end is 118mm；Screw diameter changes After change, the spiral of screw rod every section is designed amendment, after processing experiment repeatedly, draws data below: the first spiral 27 pitch are 1.6-1.7mm, the first spiral 27 stupefied size 40mm*2mm of spiral shell, and inclination angle is 4 °, and the second spiral 28 pitch is 1.8- 1.9mm, the second spiral 28 stupefied size 36mm*1mm of spiral shell, inclination angle is 4 °, and the 3rd spiral 29 pitch is 1.3-1.4mm, the 3rd spiral 29 stupefied sizes 30mm*2mm of spiral shell, inclination angle is 4 °, and the 4th spiral 30 pitch is 1.8mm, the 4th spiral 30 stupefied size 18mm*1mm of spiral shell, Inclination angle is 4 °, and the 5th spiral 31 pitch is 1.5-1.6mm, the 5th spiral 31 stupefied size 88mm*3mm of spiral shell, and inclination angle is 9 °, the 6th spiral shell Revolving 32 pitch is 1.8-1.9mm, the 6th spiral 32 stupefied size 80mm*3mm of spiral shell, and inclination angle is 9 °, and the 7th spiral 33 pitch is 2.3mm, the 7th spiral 33 stupefied size 84mm*3mm of spiral shell, inclination angle is 9 °；First spiral the 27, second spiral 28, the 3rd spiral 29, The spiral size of four spiral the 30, the 5th spiral the 31, the 6th spirals 32 and the 7th spiral 33 all differs so that slip is in screw rod Pressure suffered by diverse location also differs, and can preferably be extruded by the slip after screw rod, thus the type of molding Material density is higher, it is possible to meet standard-required；Linkage section 25 is formed around rib block 26, and the machine that assists in extruding when connecting drives screw rod Rotate；Being cased with barrel outside twin screw, barrel is customized according to the size of screw rod so that the cooperation of screw rod and barrel is satisfied to be set Meter and processing request, it is ensured that being smoothed out of processing；
3rd step: by PVC:25kg, reclaimed materials powder: 100kg, CPE:6kg, rutile titanium white lead: 2kg, ACR:0.5kg, PE wax: 0.1kg, calcium zinc stabilizer: 2.5kg, fire retardant: 6kg, brightening agent: 10g, ultramarine: 3g join 65 twin-screw extrusions of standard In machine, form sandwich layer slip through extruding；
4th step: sandwich layer slip and top layer slip are filled in mould respectively, mixing extruding in mould, form section bar；
Two charging apertures of mould carry out slip perfusion simultaneously, and in charging aperture 14, perfusion is to go out in standard 65 double screw extruder The sandwich layer slip come, sandwich layer slip flows through flat flow channel 15, first flow the 16, second runner 17 and the 3rd runner 18 and forms section bar Profile, the top layer slip of extrusion enters core material runner 23 through upside charging aperture 22 in 47 double screw extruders, then through the 3rd stream Road 18 entrance can flow plate 3, and in the 3rd runner 18 that can flow plate 3, top layer slip and sandwich layer slip carry out flowing, and top layer slip exists Section bar is carried out cladding process, then through the 3rd runner 18 and the discharging of the second mouth template 1 of first template 2 in cladding road 24 Mouth 23 extrusion die molding；Die size is 600mm*400mm, template thickness 25-50mm, and the twice for existing mold is many, mould Tool inner flow passage diameter increases, so that the molding that the slip entered in mould disclosure satisfy that the section bar of multiple discharging opening 23 is wanted Ask；Cladding road 24 is designed as outside the 3rd runner 18 one week, it is possible to the 3rd runner 18 inner profile is coated with by realization entirely Operation, thus produce and be entirely coated with section bar；Between mould, located pin positions, it is ensured that assembly precision, and uses screw It is attached, the course of processing will not occur the displacement of mould；After-poppet 5 two ends are provided with fixed mount 22, can be to mould It is fixed operation, it is ensured that adding stablizing of man-hour；In mould, the 3rd runner 18 can be 6 articles, it is also possible to is 8, even more Many, a multi-cavity mold is to be designed to realize mould one to go out many operations, as long as the slip of perfusion disclosure satisfy that requirement, it is possible to real Produce the work of many section bars the most simultaneously；
It is done that the present invention answers country to advocate building material " environmental protection, promotion waste and old material regeneration of developing a circular economy " The design of novel process and the improvement of equipment die；The present invention is according to the characteristic of PVC material, the material that " secondary plasticizing " is brought The secondary release of material performance, is adding some simple auxiliary agents so that the material resources performance of the script of product is greatly improved；Top layer is expected Effectively solve unstability and precipitation problem that products application Environment-friendlycalcium calcium zinc stabilizer is brought, and because lead salt stabilizer has Micro-poison and do not possess acid rain preventing effect and be eliminated not use；Top layer material consumption is less, and the present invention improves the cost of top layer material, So that product more glossiness and aging-resistant performance；Waste and scrap cannot be reclaimed profit by original technique in a large number With, and the present invention utilizes the ratio of waste material can reach about 70%, effectively reduces cost, and waste materials is carried out back Receive and utilize, it is to avoid the pollution of environment and destruction.
The top layer of the present invention uses different formula with sandwich layer, and sandwich layer requires relatively low, so need not add the auxiliary of costliness Help additive, and use substantial amounts of reclaimed materials, substantial amounts of Material Cost can be saved, reduce extra the taking needed for waste disposal With, it is possible to effectively control cost；47 twin screw used in the present invention, it is possible to strengthen the density of the slip extruded so that The slip made by reclaimed materials is used to disclosure satisfy that national standard requirement；The mould of a multi-cavity mold used during production, passes through Increase size and the diameter of mould inner flow passage of mould, it is achieved multiple flow passages works simultaneously and produces the full purpose being coated with section bar, adopts Go out many processing modes with one, thus improve work efficiency, improve volume of production.
The present invention uses the formula that sandwich layer is different with top layer, both ensure that the property needed for top layer, and had reduced again core The cost requirement of layer, it is achieved that reduce cost and ensure the unification of quality, and certain resource can be reduced by reclaiming old material Waste.
