Abstract
A graular material used to prepare the water-supplying UPVC pipe is prepared from PVC resin, thermal stabilizer, machining assistant, lubricant, anti-impact modifier and pigment through proportional mixing, heating whilek neading, cooling in cold mixer, extruding out, granulating and cooling.
Description
One, affiliated technical field
The present invention relates to the plastic new material field, specifically a kind of feedwater UPVC pipe fitting pellet.The invention still further relates to the preparation method of this pellet.
Two, background technology
China's water supply network is main in the past to adopt cast iron pipe, steel pipe and concrete pipe, but has short, the defectives such as difficulty, maintenance cost height of constructing of life-span.Under the effort of government promoted, plastics tubing was all progressively being used in various places in recent years.The UPVC pipe is to use plastics tubing the most widely, and it has higher erosion-resisting characteristics and chemical resistance, and it can add different auxiliary agents according to the service requirements difference in the course of processing, make it satisfy different requirements.UPVC tubing mainly is that PVC powder and auxiliary agent are directly extruded and formed, and the UPVC pipe fitting mainly is earlier with PVC powder and auxiliary agent extruding pelletization, and injection forming forms again.Therefore, making a kind of feedwater uses the pipe fitting pellet most important.
Three, summary of the invention
The purpose of this invention is to provide that a kind of processibility is excellent, good stability, physical and mechanical properties is good, sanitation performance good, and smooth surface, bubble-free feedwater is with UPVC pipe fitting pellet.
Another object of the present invention provides the preparation method of this feedwater with UPVC pipe fitting pellet.
Realize that the technical scheme that purpose of the present invention adopts is: feedwater with the mass component of UPVC pipe fitting pellet is:
Polyvinyl chloride resin 100
Thermo-stabilizer 1.5～3.5
Processing aid 0.5～2.5
Impact modifier 6～10
Lubricant 1～3
Tinting material 0～3.
Said polyvinyl chloride resin wholesomeness is good, and residual vinyl chloride monomer is less than 5ug/g; The K value is generally less than 65, few brilliant point and black yellow point, and high thermostability generally selects for use side chain few, the PVC of even molecular weight distribution.
Said thermo-stabilizer is the organic tin thermo-stabilizer, Ca-Zn composite heat stabilizer and/or these compounds.Thermo-stabilizer must be nontoxic, and consumption is few, the thermal stability height, and feed back is stablized.Organic tin thermo-stabilizer and calcium zinc type thermal stabilizing agent are the excellent thermo-stabilizers of over-all properties.Adding proportion generally is an organic tin thermo-stabilizer 1.5～2.5%, calcium zinc type thermal stabilizing agent 2.5～3.5%.
Said processing aid is an acrylic copolymer.Processing aid is in order to improve the processing fluidity of resin, to improve the surface quality of goods, after the adding, accelerated the gelation speed of resin, having improved processing characteristics and throughput.
Said lubricant divides internal lubricant and external lubricant two classes, and internal lubricant has the saturated alcohol ester of di-carboxylic acid, stearic acid list glyceride, stearic acid and series product and/or these compounds.Internal lubricant is to promote that force of cohesion destroys between the molecule, and molecule flows and the material of reduction melt viscosity mutually; External lubricant is the mixture of paraffin, polyethylene wax, oxidized polyethlene wax and/or these compounds.External lubricant is to reduce interparticle friction, prevents the material of melt and metallic surface adhesion.
Said impact modifier is the mixture of chlorinatedpolyethylene (CPE), methymethacrylate, divinyl, styrol copolymer (MBS) and/or these compounds.Impact modifier can change the fragility of PVC, improves the resistance to impact shock of feedwater with the UPVC pipe fitting.
Said tinting material is the black pigment of particle diameter 10～30nm, the mixture of Rutile type Titanium Dioxide and/or these compounds.Tinting material should be good with the PVC consistency, easily disperses sun-proof.
Preparing feedwater with the method for UPVC pipe fitting pellet is: various components get all the ready also weighing good after, earlier solid materials being placed high speed heat kneading machine mixing time is 8～10min, rotating speed 800～1500r/min, added the liquid ingredient remix 4～5 minutes, when making material temperature rise to 100～110 ℃, material is put into the cold kneader of low speed to be mixed, up to material temperature drop to 35～45 ℃, the material that mixes is placed the conical double screw extruder granulation; Temperature from feeding section to the mouth mould is: 140 ℃～185 ℃.
The present invention has adopted the above-mentioned pellet that makes, and through the injection moulding machine injection moulding, processibility is good, good stability, its product surface is smooth, color and luster evenly, flawless, no bubble, physical and mechanical properties is good, sanitation performance is good.
