Abstract
The invention discloses a modified thin-wall transparent polyvinyl chloride drip irrigation zone preventing alga growth. The modified thin-wall transparent polyvinyl chloride drip irrigation zone is applied to the field of agricultural water-saving irrigation facilities. The modified thin-wall transparent polyvinyl chloride drip irrigation zone is prepared from high-density polyethylene, low-density polyethylene, linear low-density polyethylene, alga growth preventing auxiliary materials and multifunctional master materials. The alga growth preventing auxiliary materials are prepared from ethylcellulose microencapsulation copper sulfate powder. The drip irrigation zone is good in alga growth preventing effect and long in acting time.
Description
Technical field
The invention belongs to water-saving drip tape technical field, particularly relate to a kind of modification anti-algal grown thin-walled transparent polyvinyl chloride drip irrigation zone.
Background technology
The transparent drip irrigation zone of thin-walled take polyvinyl chloride as main raw material, be prepared from by adding the raw materials such as high density polyethylene(HDPE), Low Density Polyethylene, linear low density polyethylene, multifunctional concentrate, there is the advantages such as tensile strength is good, fire-retardant, corrosion-resistant, electrical insulation capability, but corresponding it also has the easily shortcoming such as growth algae.Owing to being transparent drip irrigation zone, and be laid on more than earth's surface, very easily in direct sunlight in inner tubal wall growth algae, water dropper on drip irrigation belt resulted in blockage, its application is extremely restricted.
Summary of the invention
The present invention is for solving in known technology the technical problem existed and the anti-insect bite polychloroethylene drip irrigation tape of a kind of modification provided.
The present invention solves the technical problem existed in known technology by the following technical programs: a kind of modification anti-algal grown thin-walled transparent polyvinyl chloride drip irrigation zone, be prepared from by the raw material of following massfraction, the high density polyethylene(HDPE) of 55-60 part, the Low Density Polyethylene of 15-25 part, the linear low density polyethylene of 15-25 part, the copper sulfate of 1-2 part, 1-2 part multifunctional concentrate.
Further, copper sulfate is purity is analytical pure medicine.
Further, described ethyl cellulose microcapsule copper sulphate powder obtains by the following method: ethyl cellulose adds in organic solvent and forms solution C by (1); (2) copper sulphate powder is joined in solution C, then add emulsifying agent, form emulsion D; (3) emulsion D is added deionized water for stirring heating, evaporation of organic solvent, obtain ethyl cellulose microcapsule copper sulfate particle by after products therefrom filtration, drying.
Further, described multifunctional concentrate is that moisture absorption foam eliminating mother particle was both made up of metal oxide, resin and auxiliary agent.
Further, drip irrigation zone is transparent and wall thickness is less than or equal to 0.15mm.
The advantage that the present invention has and positively effect are:
1, efficiently prevent algal grown because copper sulfate has, avoid the feature of phycophyta blocking dropping head, compare common polychloroethylene drip irrigation tape by additionally adding copper sulphate powder in formula, there is the performance preventing algal grown.
2, produce Salzburg vitriol blue powder because copper sulfate very easily absorbs water in air, copper sulfate is prepared into ethyl cellulose microcapsule particle, can ensure that copper sulfate can not absorb water sex change.And this anti-algal grown auxiliary material is applied in drip irrigation zone, it also avoid the water-soluble loss causing anti-algae composition of copper sulfate, ensured the lasting of anti-algae effect.
3, taking ethyl cellulose as wall material, is because ethyl cellulose has good hydrophobicity, avoids the composition caused because of weather conditions after drip irrigation zone is laid on field equally and runs off, it also avoid the pollution to surrounding enviroment.
Embodiment
Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
It is below all commercially available acquisition of each raw material related in embodiment.
Embodiment 1, the preparation of ethyl cellulose microcapsule copper sulfate particle, 6g ethyl cellulose adds in organic solvent in (chloroform) by (1), obtained ethyl cellulose solution; (2) 0.3g copper sulphate powder is placed in ethyl cellulose solution, then adds 2.5mlOP-10 emulsifying agent and cetyl trimethylammonium bromide (CTAB) dispersion agent, ultrasonic agitation 45 minutes, form emulsion; (3) add in deionized water by emulsion in (2), mechanical stirring also heats, and now it should be noted that emulsion adds speed is 3ml/min, after adding, emulsion is heated with stirring to about 65 DEG C, obtains microcapsule granule; (4) products therefrom is filtered and drying, obtain copper sulfate microcapsule granule.
A kind of modification anti-algal grown thin-walled transparent polyvinyl chloride drip irrigation zone, is prepared from by the raw material of following massfraction, the high density polyethylene(HDPE) of 55-60 part, the Low Density Polyethylene of 15-25 part, the linear low density polyethylene of 15-25 part, the copper sulfate of 1-2 part, 1-2 part multifunctional concentrate.
Embodiment 2, the preparation of a kind of modification anti-algal grown thin-walled transparent polyvinyl chloride drip irrigation zone, by the high density polyethylene(HDPE) of 55kg, the Low Density Polyethylene of 25kg, the linear low density polyethylene of 25kg, the multifunctional concentrate of 1kg adds in co-extrusion machine, adds in little co-extrusion machine by the micro encapsulation copper sulfate in 1.0kg embodiment 1, preheating under 200-220 DEG C of condition, then extrudes through former, cools, shapes, draws and get final product under 240-280 DEG C of condition.
Embodiment 3, the preparation of a kind of modification anti-algal grown thin-walled transparent polyvinyl chloride drip irrigation zone, by the high density polyethylene(HDPE) of 55kg, the Low Density Polyethylene of 25kg, the linear low density polyethylene of 25kg, the multifunctional concentrate of 1kg adds in co-extrusion machine, adds in little co-extrusion machine by the micro encapsulation copper sulfate in 1.5kg embodiment 1, preheating under 200-220 DEG C of condition, then extrudes through former, cools, shapes, draws and get final product under 240-280 DEG C of condition.
