Abstract
A color PVC section is prepared from the red mud as the industrial waste, composite stabilizer K2020N and PVC through pugging and shaping. Its advantages are coffee colour, smooth handle, low cost and long service life.
Description
Technical field:
The present invention relates to a kind of production method of color plastic profile, the production method of particularly a kind of color polyvinyl chloride (PVC) section bar.
Background technology:
In actual applications, white PVC section bar exists problems such as easy pollution, yellowing on ageing.Also need to use colored PVC section bar in a lot of occasions simultaneously, in producing colored PVC section bar process, often need titanium dioxide and tinting material (Masterbatch), increased production cost of products, and the product of being produced is subjected to the easy weather stain of uviolizing when using out of doors or forms the be full of cracks speckle on the surface of product.
Summary of the invention:
The objective of the invention is to provide a kind of production method of color plastic profile, the color plastic profile of producing in this way has characteristics such as cost is low, long service life.
In order to reach the production method that purpose of the present invention takes being, is main raw material with polyvinyl chloride (PVC), adds red mud and K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene and carries out batch mixing, through the plastics extruder extrusion moulding.
The red mud that polyvinyl chloride and drying-screening is handled, K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene are that 100: 6～50: 5～18: 1～4: 7～14 ratio is carried out batch mixing according to weight ratio, carry out fusion, plasticizing after mould shape by plastics extruder.
Wherein the batch mixing weight ratio of red mud and K2020N one package stabilizer is 1: 0.25～1; The batch mixing weight ratio of red mud and properties-correcting agent is 1: 0.15～0.65; The batch mixing weight ratio of red mud and chlorinatedpolyethylene is 1: 0.312～1.15.
The temperature that red mud is dried is 90～120 ℃ in process of production, and the time is 30～60 minutes.
The concrete steps of this method are: polyvinyl chloride, red mud and K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene are put into high-speed mixer carry out batch mixing, entering low speed mixer after reaching 98～118 ℃ cools off, and discharges when reaching 40～45 ℃; Wherein available optimum temps is 110 ℃.
The production technique of color plastic profile of the present invention is as follows:
Oven dry processing-screening-batch mixing-extrude-finalize the design cooling-traction sawing-windrow to tie up
1, oven dry is handled: with tunnel furnace or heating container red mud is dried.90～120 ℃ of bake out temperatures, 30～60 minutes.
2, screening: remove the impurity that enters red mud in the processes such as transporting production.
3, batch mixing: polyvinyl chloride resin and red mud, K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene are added high-speed mixer in proper order according to 100: 6～50: 5～18: 1～4: 7～14 ratio, mix.Reach and enter low speed mixer after 98～118 ℃ (optimum value is 110 ℃) and cool off, discharge when reaching 40～45 ℃.
4, extrude: the raw material after will mixing adds forcing machine, carries out fusion, plasticizing after die head is extruded in forcing machine, forms parison.Die head that conversion is different and stock mould promptly can be made into the section bar of different size, shape.
5, typing cooling: the material of extruding is in cooling apparatus for shaping, and through the stock mould Vacuum shaping, the spray cooling forms shape and size that goods require.
6, traction sawing: tubing after the moulding or section bar, are constantly drawn under the effect of tractive force through tractor, cut off into certain-length (6m or 4m) by cutting unit.
7, tie up: tubing or section bar are tied up by some amount on the windrow device.
The present invention carries out mixing with the industrial residue-red mud of alumina producing enterprise output and K2020N one package stabilizer and polyvinyl chloride (PVC), produce colored PVC section bar, when its difference with the prior art is to produce colored PVC section bar, titanium dioxide, tinting material (Masterbatch) have been save, and vast scale adds industrial residue-red mud in process of production, therefore makes production cost reduce more than 10% than common PVC.Red mud and K2020N one package stabilizer have improved the anti-ultraviolet aging performance of PVC and have prolonged the work-ing life of product.The product appearance color is the natural coffee look, metal luster, and colourity is full, is smooth to the touch, and has the excellent decoration effect, and under long-time sunshine condition, is difficult for weather stain, and be 2 times of common PVC section bar its work-ing life.The present invention is applicable to water service pipe, water shoot, plastic door-window, sheet material and the profiled material of producing PVC series, has good social, economic benefit.
Embodiment:
Application example of the present invention is as follows:
Application example 1: produce colored water service pipe
Batch mixing (weight) ratio of PVC and red mud, K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene is 100: 32: 10: 2: 8; (PVC is a food grade) die head of plastic extruding machine is standard φ 20, and the Vacuum shaping mould is standard φ 20, processes according to the aforementioned technological process of production, promptly makes coffee-like water service pipe.
Application example 2: produce colored plastic-steel window
The batch mixing ratio of PVC and red mud, K2020N one package stabilizer, properties-correcting agent, chlorinatedpolyethylene is 100: 20: 7.92: 1.76: 7.825.
PVC is a technical grade, and die head of plastic extruding machine is standard 80 sash, and the Vacuum shaping mould is standard 80 sash.Process according to the aforementioned technological process of production, promptly can be made into coffee-like plastic window 80 sectionals.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
