Description
Technical field
The present invention relates to the plastics saving product of water, especially fluoropolymer process aid modification drip irrigation zone.
Background technology
Xinjiang is Irrigation farming district, typical arid oasis, builds the key that water-saving agricultural is an agricultural sustainable development.Full boundary 2010 is 2,440 ten thousand mu of developing agricultural high-efficiency water-saving irrigated areas; Wherein the drip irrigation area is about 1,500 ten thousand mu; The drip irrigation economize technology is the agricultural irrigation technology that extensively promote the use of in Xinjiang, is the fourth-largest capital goods in the agricultural sector after agricultural chemicals, chemical fertilizer, mulch film.Drip irrigation has actual water-saving and yield-increasing effect, and dripping pipeline as important in the system and be exposed to the face of land in the drip irrigation zone, suffers being exposed to the sun of the sun for a long time; Rainwater weather, pyritous wear out; Because labyrinth, drip irrigation zone face is thin and the problem of water pressure resistance poor performance, cause the drip irrigation zone booster and labyrinth thorn water phenomenon often to occur, influenced normal irrigation; Then take a lot of work and delay farming season if will keep in repair or change; Especially the summer high-temperature weather longer duration in Xinjiang, Xinjiang is the multi-form agriculture production of intensification in addition, the problems referred to above are particularly outstanding.Traditional processing technology must reduce the adding proportion of recycled polyethylene in the prescription of drip irrigation zone and even must not use if will address the above problem, and the raising that this just causes the drip irrigation zone production cost makes drip irrigation zone performance and cost not to get both.Along with the increase of using the drip irrigation time limit; The recycling repeatedly of drip irrigation zone; And the negative impact that produces becomes clear day by day; Cause existing drip irrigation zone recycled polyethylene adding proportion low, cost is high, poor, the production process problem of unstable of withstand voltage properties, and April in 2008 one piece " fluoropolymer additive is produced the application in the dropper band at the PE reworked material ", article was published in " New Chemical Materials " also has argumentation to this.
Summary of the invention
The object of the present invention is to provide a kind of under the condition of satisfy using, low, the good pressure-resistant performance of cost, the fluoropolymer process aid modification drip irrigation zone of stable production process.
A kind of fluoropolymer process aid modification drip irrigation zone comprises the component that contains following umber: 10～90 parts of recycled polyethylenes, 10～90 parts of polyvinyl resins, 0.2～3 part of fluoropolymer process aid, 1～6 part of anti-aging master batch.The fluoropolymer process aid that made full use of this prescription can improve carbon black and the dissemination of mineral filler in polyvinyl resin; Reduce recycled polyethylene and oxidation gel and the cross linked gel phenomenon of polyvinyl resin in extrusion; Thereby improve the flowability and the stripping result of blend melt; Improve the processing characteristics of blend, taken into account the drip irrigation zone product performance simultaneously.Being widely used in industries such as agricultural, industry of planting forest or fruit tress, greening lawn uses.Have good society and economic benefit.
Above-mentioned fluoropolymer process aid modification drip irrigation zone, anti-aging master batch are 1～3 part of antioxygen masterbatch and 1～3 part of black masterbatch; Purpose is the duration of service that prolongs the drip irrigation zone, takes all factors into consideration and wants fast light oxygen aging and thermo-oxidative ageing.
Above-mentioned fluoropolymer process aid modification drip irrigation zone, polyvinyl resin are one or more the compsn in high density polyethylene(HDPE), LLDPE or the new LDPE (film grade); High density polyethylene(HDPE) is high because of tensile strength, water pressure resistance.Wear resisting property is good, so large usage quantity; LLDPE molecular chain linearly type has less side chain, and narrow molecular weight distribution, mechanical property are high than new LDPE (film grade); And low, the good processability of new LDPE (film grade) melt viscosity, the three reaches the perfect adaptation of performance and cost value according to suitable proportioning.
Above-mentioned fluoropolymer process aid modification drip irrigation zone, polyvinyl resin are 5～45 parts of high density polyethylene(HDPE)s and the mixture of 5～45 parts of LLDPE or new LDPE (film grade)s.Purpose is to make full use of high density polyethylene(HDPE) tensile strength height, and the water pressure resistance performance is good, cooperates low, the good processability of LLDPE or new LDPE (film grade) fusing back viscosity, and the elongation at break of drip irrigation zone is high.

Above-mentioned fluoropolymer process aid modification drip irrigation zone, polyvinyl resin are the mixture of 5～20 parts of 5～45 parts of high density polyethylene(HDPE)s, 5～25 parts of LLDPEs and new LDPE (film grade)s.Purpose is to make full use of high density polyethylene(HDPE) tensile strength height, and the water pressure resistance performance is good, cooperates low, the good processability of LLDPE or new LDPE (film grade) fusing back viscosity, and the elongation at break of drip irrigation zone is high.Can also enlarge simultaneously the use range of raw material.
The technical scheme that realizes goal of the invention is to solve like this: the fluoropolymer process aid drip irrigation zone is to be raw material with fluoropolymer process aid, recycled polyethylene and polyvinyl resin and anti-aging master batch thereof; Mix by a certain percentage; After forcing machine is extruded according to the certain process temperature; Blowing, mould wheel shaping cool off at last, draw, remember that rice, rolling promptly are prepared into fluoropolymer process aid modification drip irrigation zone.
Because of the present invention has added fluoropolymer process aid; Along with the increase of fluoropolymer process aid consumption, the recycled polyethylene adding proportion progressively improves, and the adding of fluoropolymer process aid has the gentle material of the extrusion of reduction material compression functions; Be beneficial to forming process more; Caused the minimizing of other auxiliary dosage, the fluoropolymer process aid addition is few simultaneously, and production technique is simple.The comprehensive cost of drip irrigation zone can reduce 100-500 unit/ton, and next uses fluoropolymer process aid, does not only influence original processing conditions (like technological temperature); And similar with the polyvinyl resin fusing point, because the surface tension of fluoropolymer process aid is much littler than the surface tension of polyvinyl resin, fluoropolymer process aid is not fused to the polyethylene blend resin melt; But fluoropolymer process aid and forcing machine steel cylinder, screw rod, head, mouthful mould metallic surface have the trend of adhering to of height; Like this after adding an amount of fluoropolymer process aid in the polyethylene blend resin, effective ingredient slowly sees through the polyethylene blend melt and moves to the mold runner surfaces coated and attach the mold runner inside and outside wall in the fluoropolymer process aid, makes and forms lubricant film between die surface and polymer melt; Reduce the friction that melt produces with wall in moving process; And then reduce shearing rate and the viscous of melt in mould and pull, postpone the generation of shark skin phenomenon, thereby improved the outward appearance of drip irrigation zone product; Having reduced the material of extrusion presses and the material temperature; The quality problems of rigid piece are able to solve, and this coating is in running balance in continuous extrusion, after running balance is stable; Production process and drip irrigation zone quality product will reach stable, so fluoropolymer process aid plays the effect of efficient external lubricant.
