Beneficial effect of the present invention: the PVC coiled material floor rich color that the present invention produces, surfacing is smooth, and inner density is good; The PVC coiled material floor even thickness of producing.The present invention adopts hot-forming method, and compared with traditional batch (-type) pressure sintering, production efficiency is greatly enhanced.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
A production technology for PVC coiled material floor, is characterized in that, comprises the following steps:
(1) mediate blend: polyvinyl chloride resin is added to high-speed mixer, stir material temperature and increase the temperature to 80 DEG C, add calcium-zinc composite stabilizing agent, add dioctyl phthalate, di-n-octyl sebacate in 85-90 DEG C of interval, temperature adds inorganic pigment, paraffin and stearic acid while being elevated to 95 DEG C, temperature adds magnesium hydroxide, the aluminium hydroxide through coupling agent treatment while being elevated to 100 DEG C, be discharged in cold mixed pot and be cooled to below 40 DEG C 110 DEG C time, and blanking is for subsequent use;
(2) extrusion plasticizing: the material of step (1) is sent into double screw extruder by conveying worm and fully heat, shear, plastify, entering single screw extrusion machine further heats, plastifies again, the dry blend of different colours should be distinguished extrusion plasticizing, in order to avoid there is aberration, through the material of plasticizing should plastify evenly, solid colour, the closely knit pore-free of section;
(3) granulation fragmentation: revolve cutter by outlet and cut off granulation, finally each color PVC particle of making is cooled to room temperature, the pellet making is random multi-angular rubble shape;
(4) sieving and grading: determine hierarchy plan according to the color pattern of PVC coiled material floor, respectively pellet is carried out to sieving and grading by color, stand-by after packaging, the size of granulation is 10-50 order, is 0.28-1.9mm;
(5) batching is mixed: according to the color pattern of PVC coiled material floor, drop in mixer and carry out blend by the learn from else's experience pellet of different colours of sieving and grading of certain mass score another name, fully mix rear stand-by;
(6) prepare base material: batching PVC particle in step (5) is mixed in mixer, enter extruder PVC particle is puddled, gradually plasticizing, revolves cutter by outlet and cuts off granulation, be transported to flattener and be squeezed into base material, base material thickness is 0.8-2.0mm;
(7) apply: the pellet after sieving and grading is coated in to the substrate surface that step (6) prepares, and coating speed is 0.1-2.0m/min, hot-forming, embossing, cooling, surperficial UV process, and the product obtaining is PVC coiled material floor.
Coating needs coating machine, applies platform and shield.The width that applies platform is greater than shield, for base material and the operation of shield horizontal stable, when hot-forming, shield one side is as the carrier of base material, can play on the other hand the effect of the rear follow-up band of leader band, its width is not less than the width of PVC coiled material floor, and the length of Length Ratio PVC coiled material floor is long, thickness is answered uniformity, to facilitate coating.
PVC coiled material floor is to form by flat drum type vulcanizing machine processing and forming.
Hot-forming, in the time that semi-finished product and shield are imported between heating drum and pressure steel band, under the effect of pressure and heat, pellet is by compacting gradually and discharge pellet and pile up the air in the hole producing.Meanwhile, pellet absorbs a large amount of heats, and in the time that intermolecular activity can be greater than intermolecular active force, pellet molecule segment and whole large molecule will produce freely-movable.Along with strand absorbs increasing of heat, pellet is from glassy transition viscous state, and under the continuous action of pressure, strand starts to flow, and at this moment pellet changes molten state into, entangled to each other between strand.Along with the effect of pressure, heat, intermolecular spacing is dwindled, and tangles to put and increase, and at this moment solid grain combines together, forms the closely knit plane without hole on smooth heating drum surface.In this process, base material is subject to hot conduction and pressure-acting equally, and in the time that solid grain combines together, base material is alternate with pellet two also to become one by conduction melting.Along with the rotation of heating drum, the semi-finished product that are coated in drum surface shift out heating drum gradually, no longer be subject to the effect of heat and pressure, the semi-finished product that combine together contact with air, temperature declines gradually, and intermolecular force increases gradually, and strand just increases, vitrifying state while returning to normal temperature gradually, PVC coiled material floor is made.
Above content is only to structure example of the present invention and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of invention or surmount this scope as defined in the claims, all should belong to protection scope of the present invention.
