Agricultural thin-wall micro drip tube and making method thereof



The invention discloses a making method for an agricultural thin-wall micro drip tube. The preparation steps include: 1) mixing raw materials according to the following mass part: 10-50 parts of ethylene-vinyl acetate copolymer (EVA), 80-120 parts of linear low density polyethylene (LLDPE), 0.01-0.1 part of an antioxidant and 1-5 parts of carbon black masterbatch, then fully stirring the materials for 8-12min by a stirrer, and then performing blending granulation by a single screw extruder; and 2) subjecting the granules prepared by step 1) to extrusion by a tube machine and a tube extrusion auxiliary machine, cooling, shaping, traction, and coiling by a coiling machine, thus obtaining the finished tube. The novel thin-wall micro drip tube for agriculture, horticulture and other industries has the advantage of low cost, good water saving property, cold resistance and ageing resistance, etc. The novel thin-wall micro drip tube has longer service life than ordinary micro drip tubes, and is convenient to use and install.
