Abstract
The present invention relates to a process for preparing an antibacterial material for a micro irrigation irrigator. The antibacterial material is utilized to penetrate low pressure and high density polyethylene plastics; a dispersing agent, a coupling agent and an auxiliary agent are added, and the antibacterial material for a micro irrigation irrigator can be fabricated and formed on an irrigator production line. The antibacterial material which is an organic-inorganic series compound antibacterial material comprises the following main antibacterial components: pyridinium salt, chlorophenol, tetravalent ammonium salt, a biguanide chemical compound, ethanol, quaternary ammonium salt and silver organic complex ions. Due to the adoption of the organic-inorganic series compound antibacterial material, the dosage of the silver can be reduced, and the cost is greatly reduced; in addition, organic-inorganic antibacterial components, Ag ++ and various organic antibacterial ingredients can be slowly released to continuously replenish the lost antibacterial ingredients at the material surface through migration effect to destroy microbe cell membranes and a respiratory system so that hindered protein denaturation, hindered cell wall denaturation and hindered-SH acidification and metabolism are principal sterilization mechanisms. The organic-inorganic series compound antibacterial material has the characteristics of broad-spectrum antibacterial action, timely high efficiency sterilization, no poison, endurance and low price.
Description
One, technical field
The invention belongs to the new high-tech material field, particularly a kind of preparation technology who is used for the micro-irrigation emitter anti-biotic material of agricultural water-saving irrigation.
Two, background technology
The various conduit components and the micro-irrigation emitter that are used for the agricultural water conservation slight irrigation all are made of plastic, irrigator as the slight irrigation end, be distributed with the slow water flow passage of very fine complexity on it, the effect of landing low water flow rate and impurity screening, after the higher current of pressure enter irrigator, through the irrigator energy dissipating, splash into soil with the stabilized uniform low discharge, reach the purpose of water-saving irrigation.Obviously improved irrigation quality although it is so, improved the availability of irrigation water, but because frosting is easily by microbial contamination, all exist a large amount of microorganisms in the water source, except very common iron bacteria, also have microorganisms such as algae, sulphur bacteria, sulfate reducing bacteria, fungi and zoogloea can both in aqueduct, form ooze.To form ooze in water for industrial use known already because of it for common blue algae in the algae, green algae, diatoms.These algae volumes are little, and breeding is fast, therefore are difficult to leach and control.And the not enough 1mm of irrigator flow diameter, minimum only have a 0.2mm, and flow channel length is longer relatively, fluidised form is near laminar flow, because temperature, humidity are suitable, these microorganisms are easy to grow in the runner of irrigator, and water dropper, drip irrigation pipe, irrigate band and the mini sprinkler of irrigator are stopped up.Blockage problem is the biggest obstacle of slight irrigation development always, and it is the obstruction of irrigator that outstanding behaviours is stopped up in slight irrigation, and the quality that blockage problem solves is directly determining the service life and the application benefit of engineering.In various slight irrigations are stopped up, grow the irrigator obstruction that causes by microorganism and accounted for significant proportion.The way that solves mainly is to add a certain amount of chlorine or chlorine liquid in the irrigation water of drip irrigation, adopt ozone sterilization and increase the circulation flushing operation at present, but makes the cost of slight irrigation significantly rise like this.So, use high-new anti-biotic material and make antibiotic micro-irrigation emitter, in time kill the microorganism in the water that enters irrigator, can fundamentally solve the microorganism blockage problem of micro-irrigation emitter.
Three, summary of the invention
The object of the present invention is to provide and a kind ofly can suppress various mushrooms, algae growing in irrigator, improve the preparation technology of the micro-irrigation emitter anti-biotic material of the anti-stifled ability of irrigator.
For achieving the above object, the preparation technology that the present invention adopts is: be 2 of 0.003M with concentration at first, 2 '-bipyridyl silver or 1, the complex ion aqueous solution of 10 phenanthroline silver and purity are greater than 95% the bentonite with layer structure, montmorillonite, saponite class clay, salt of phosphoric acid or ask vigorous mullite by solid: liquid 1: 25-1: 30 volume ratio reaction bonded, make a layer structure antibacterial agent material that carries silver; Secondly, utilize interlayer to insert with percent by volume to be: 0.2%～1.1% pyridiniujm, 0.3%～1% chlorophenol, 0.2%～0.8% tetraacetyl ethylene diamine or hexamethylenetetramine, 0.5%～0.9% lipophilic poly-hexamethyl guanidine stearate or poly-hexamethyl two guanidine stearate, 0.4%～1.3% ethanol, 0.3%～1.5% polyquaternium or poly-bi-quaternary ammonium salt organic anti-bacterial component are incorporated in the layer structure antibacterial agent material that carries silver, and making organic and inorganic is composite antibacterial material; At last, with percent by volume be: 0.5%～1.8% organic and inorganic is that composite antibacterial material infiltrates in the low-pressure high-density polyethylene plastics, gets final product with the dispersant of 0.5%～2% low-molecular polyethylene wax as anti-biotic material.
The present invention also can add volume ratio in vinyon be 0.2%～1% calcium chloride or calcium carbonate, gets final product through mixing and stirring.
Because it is composite antibacterial material that the present invention adopts organic and inorganic, can reduce the consumption of silver, greatly reduce cost like this; And the organic and inorganic antibacterial components, Ag
+Can discharge together at leisure with various organic anti-bacterial compositions,, make the antibiotic irrigator surface of making have stable antimicrobial component content, make anti-microbial property effective lastingly by the antimicrobial component of the continuous supplementary material surface losses of migration.
