Abstract
A nano material modified water delivering flexible pipe used for irrigation in agricultural field features high explosion strength and tension strength, smooth surface, high anti-ageing performance, long service life and low cost.
Description
Technical field
It is soft to the present invention relates to agricultural water delivery, especially nano-material modified delivery hose.
Background technology
Because Global Climate condition and Increase of population, water globe resource supply and demand contradiction is increasingly sharpened, and China is serious water shortage country especially, and in the total water amount, irrigation water accounts for 70%.Adopt irrigation canals and ditches water delivery seepage losses and vaporization losses in the past, and adopt hydraulic pipe can reduce even stop loss, thereby significantly improved the utilization coefficient of irrigation canals and ditches water resources.Simultaneously, irrigation canals and ditches are carried out canalization, and cancellation field irrigation canals and ditches have improved land utilization ratio (1%-5%), have saved land resources, promote that agriculture production develops to mechanize, industrialization, modernized direction.Widely popularize in the process of water saving irrigation in the whole nation, often be exposed to the face of land as the important hydraulic pipe-line in the drip irrigation system, suffer being exposed to the sun of the sun for a long time, it requires the anticracking pressure of hydraulic pipe and toughness higher, and will be convenient to install.In the past, the type of hydraulic pipe mainly contained steel pipe, pvc pipe, also had common PE pipe and calico flexible pipe.But steel pipe is perishable, leaks when serious, influences production safety, and installs inconvenient.The PVC hard tube is stiff, and not flexible, fragility is big, and inconvenience is installed; It is poor that the soft pvc pipe is withstand voltage.The common PE pipe never has standard and comes science guiding to produce, and adds selection to the resin trade mark and is short in understanding and some distortion excess has occurred in using, and particularly wall thickness deviation is bigger, and causes that the situation that the joint leaks often occurs.And calico flexible pipe humidity, perishable can not prevent that moisture from oozing out.
Summary of the invention
Purpose of the present invention be exactly be to provide a kind of cost low, be convenient to install, toughness and the higher nano-material modified delivery hose of anticracking pressure.
A kind of nano-material modified delivery hose is characterized in that being made by the raw material of the component that contains following umber: 60～100 parts of polyvinyl resins, 5～40 parts of nanometer grade calcium carbonate modified materials, 0.05～8 part of processing aid.
Above-mentioned delivery hose, processing aid are lubricant (stearic acid/calcium stearate) and carbon black.
Above-mentioned delivery hose, polyvinyl resin are one or more the mixture in LLDPE, new LDPE (film grade), medium-density polyethylene or the high density polyethylene(HDPE).
Above-mentioned delivery hose, polyvinyl resin are the mixture of 5～30 parts of 50～70 parts of LLDPE or new LDPE (film grade)s and medium-density polyethylene or high density polyethylene(HDPE)s.
Above-mentioned delivery hose, polyvinyl resin are the mixture of 15～35 parts of 30～65 parts of medium-density polyethylenes and high density polyethylene(HDPE)s.
Above-mentioned delivery hose, polyvinyl resin are the mixture of 10～30 parts of 50～70 parts of LLDPE and new LDPE (film grade)s.
Above-mentioned delivery hose, polyvinyl resin are the mixture of 5～15 parts of 40～70 parts of LLDPE, 5～15 parts of new LDPE (film grade)s and medium-density polyethylene or high density polyethylene(HDPE)s.
Above-mentioned delivery hose, polyvinyl resin are the mixture of 5～15 parts of LLDPE or 25～50 parts of new LDPE (film grade)s, 15～35 parts of medium-density polyethylenes and high density polyethylene(HDPE)s.
Above-mentioned delivery hose, polyvinyl resin are the mixture of 5～10 parts of 10～40 parts of LLDPE, 5～15 parts of new LDPE (film grade)s, 15～35 parts of medium-density polyethylenes and high density polyethylene(HDPE)s.
Preparation method of the present invention: with nanometer grade calcium carbonate modified material and PE is raw material, add the certain mixed of processing aid after, fusion, the technological temperature extrusion moulding according to certain is prepared into flexible pipe through cooling, traction, rolling again.
Because of the present invention has added nanometer grade calcium carbonate modified material, increase along with nanometer grade calcium carbonate modified material proportion, resistance to impact shock increases gradually, certainly the adding of auxiliary agent mainly has been the effect that improves performance, is beneficial to processing, but cost an arm and a leg, and the adding of nanometer grade calcium carbonate modified material has the toughness reinforcing performance of enhancing, be beneficial to forming process, caused the minimizing of auxiliary dosage, nanometer grade calcium carbonate modified material price is cheap simultaneously, production technique is simple, and production cost can reduce 300-500 unit/ton.Secondly, use nanometer grade calcium carbonate modified material, not only do not influence original processing conditions (as technological temperature), and it is good with the resin intermiscibility, the inorganic particulate few surface defects of the small particle size in the used nanometer grade calcium carbonate modified material, the non-matching atom is many, specific surface area is big, big with polymkeric substance generation physics or chemically combined possibility, better dispersed, the interface bonding between particle and matrix can be born bigger load, not only strengthen but also toughness reinforcing characteristics thereby have, make the tensile strength of this flexible pipe than technical indicator high twice, elongation at break (being toughness) than technical indicator high twice many (seeing Table 1), make size have lasting stability, and wall thickness deviation is little, the situation that the joint leaks can not occur.If polyvinyl resin is the mixture of linear low density polyethylene, new LDPE (film grade) and medium-density polyethylene, everyways such as linear low density polyethylene toughness, oil-proofness and ageing resistance are strong than new LDPE (film grade) and medium-density polyethylene; But new LDPE (film grade) good processability; The medium-density polyethylene rigidity is strong, has reached the best combination of performance so according to a certain ratio, makes this nanometer grade calcium carbonate modified flexible pipe have the characteristics of good toughness, intensity height, smooth surface and long service life.Mainly be applicable to ground, farmland water conveyance irrigation.
