Abstract
A composition for the ultra-thin drip-irrigation band is proportionally prepared from medium-density polyethene, ethene-vinyl acetate, high-pressure polyethene, low-pressure polyethene, carbon black and nano-calcium carbonate.
Description
Technical field
The drip irrigation zone composition that uses when the present invention relates to slight irrigation is specially adapted to the material compositions of ultrathin strap of trickle irrigation.
Background technology
Process after the composition of existing drip irrigation zone all adopts high-pressure polyethylene and low pressure polyethylene to mix by a certain percentage, because high-pressure polyethylene toughness is better, but the Strong degree is lower, and low pressure polyethylene Strong degree is better, but toughness is relatively poor.After mixing by a certain percentage, the two can partly improve its toughness and Strong degree by Enough, but because the two density differs too big, (high-pressure polyethylene density is about 0.92, pressure polyethylene density is about 0.96), its compatibility is bad, processing characteristics is relatively poor, and particularly when the pipe that the high-speed production wall approaches, processing characteristics is just poorer.Prior art can only be produced the drip irrigation zone of wall thickness in the above specification of 0.15mm at present, and production rate is not more than 15 meters of per minutes.Have that production rate is slow, tooling cost is high, can't produce the defectives such as thin wall irrigation belt of wall thickness below 0.15mm by the prior art compositions prescription.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of and reduces the thickness of drip irrigation zone as far as possible satisfying under the working conditions, improves production rate, the material compositions of the ultrathin strap of trickle irrigation that reduces cost.
The technical scheme that realizes goal of the invention is to solve like this: the material compositions of ultrathin strap of trickle irrigation, contain high-pressure polyethylene and low pressure polyethylene, its substantive distinguishing features of the present invention is also to include 40%～60% medium-density polyethylene by mass fraction, 4%～10% ethene-vinyl acetate copolymer, 16%～22% high-pressure polyethylene, 15%～20% low pressure polyethylene, 1%～5% carbon black, 1%～5% nano-calcium carbonate.
The present invention compared with prior art, make full use of medium-density polyethylene snappiness, intensity, extrude all characteristics preferably of processing characteristics, the performance that cooperates separately cementability of ethene-vinyl acetate copolymer, high-pressure polyethylene, low pressure polyethylene, processibility, snappiness, intensity etc., add the good characteristics of carbon black energy UV resistant, nano-calcium carbonate can further improve intensity, increase the consistency of above-mentioned materials simultaneously, improve its processing characteristics.Make the production cost and the former drip irrigation zone cost of ultrathin strap of trickle irrigation reduce by 1/3rd, production rate improves more than three times, and wall thickness is reduced to below the 0.1mm.Being widely used in industries such as agricultural, forestry, greening lawn uses.Have good society and economic benefit.
Embodiment
Below in conjunction with embodiment, content of the present invention is described further:

Embodiment 5
Press the medium-density polyethylene of the 60kg of mass fraction, the ethene-vinyl acetate copolymer of 6kg, the high-pressure polyethylene of 15kg, the low pressure polyethylene of 13kg, the carbon black of 2kg, the nano-calcium carbonate of 4kg.
Embodiment 6
Press the medium-density polyethylene of the 50kg of mass fraction, the ethene-vinyl acetate copolymer of 8kg, the high-pressure polyethylene of 19kg, the low pressure polyethylene of 17kg, the carbon black of 3kg, the nano-calcium carbonate of 3kg.
In sum, the performance of each composition is as follows:
Medium-density polyethylene (MDPE): snappiness, intensity, to extrude processing characteristics all better;
Ethene-vinyl acetate copolymer (EVA): adhesiveproperties, processing characteristics are better;
High-pressure polyethylene (LDPE): snappiness is good;
Low pressure polyethylene (HDPE): intensity is good;
Carbon black: good ultraviolet resistance.
Nano-calcium carbonate (caco
3): intensity is good, increases consistency, improves processing characteristics.
