Embodiment 1

[0023] A composition of drip irrigation tape material is made of the following raw materials by weight: 100kg of high-density polyethylene resin, 5kg of colorant (carbon black masterbatch), 0.5kg of processing modifier (PPA masterbatch), 0.2 ㎏ Processing aid (calcium stearate). Accurately weigh the above-mentioned raw materials and add them into the mixer one by one. The stirring speed is 120 rpm, the temperature is set at 80°C, and the mixture is mixed for about 15 minutes. The mixed mixture is put into the twin-screw extruder, melted and extruded, cooled and cut. Pulling, the drip irrigation tape material composition granules are obtained. Among them, the temperature of each zone of the twin-screw extruder barrel is 170°C in the first zone, 180°C in the second zone, 180°C in the third zone, 195°C in the fourth zone, and 200°C in the fifth zone. The host speed is 500 r / min.

Embodiment 2

[0025] A composition of drip irrigation tape materials is made of raw materials containing the following parts: 80kg high-density polyethylene resin, 20kg low-density polyethylene resin, 5kg colorant (carbon black masterbatch), 0.5kg processing Modifier (PPA masterbatch), 0.2㎏ processing aid (calcium stearate). Accurately weigh the above-mentioned raw materials and add them into the mixer one by one. The stirring speed is 120 rpm, the temperature is set at 80°C, and the mixture is mixed for about 15 minutes. The mixed mixture is put into the twin-screw extruder, melted and extruded, cooled and cut. Pull, prepare, drip tape material composition pellets. Among them, the temperature of each zone of the twin-screw extruder barrel is 170°C in the first zone, 180°C in the second zone, 180°C in the third zone, 195°C in the fourth zone, and 200°C in the fifth zone. The host speed is 500 r / min.

Embodiment 3

[0027] A composition of drip irrigation tape material is made of raw materials containing the following parts: 60kg high-density polyethylene resin, 40kg low-density polyethylene resin, 5kg colorant (carbon black masterbatch), 0.5kg processing Modifier (PPA masterbatch), 0.2㎏ processing aid (calcium stearate). Accurately weigh the above-mentioned raw materials and add them into the mixer one by one. The stirring speed is 120 rpm, the temperature is set at 80°C, and the mixture is mixed for about 15 minutes. The mixed mixture is put into the twin-screw extruder, melted and extruded, cooled and cut. Pull, prepare, drip tape material composition pellets. Among them, the temperature of each zone of the twin-screw extruder barrel is 170°C in the first zone, 180°C in the second zone, 180°C in the third zone, 195°C in the fourth zone, and 200°C in the fifth zone. The host speed is 500 r / min.

Abstract

The invention relates to a composition of a drip irrigation zone material. The composition is prepared from the following materials in parts by mass: 100 parts of polyethylene resin, 5-10 parts of a coloring agent, 0.5-2 parts of a processing modifier and 0.01-1 part of a processing assistant. The preparation method of the composition comprises the following steps: adding the coloring agent, the processing modifier and the processing assistant into the polyethylene resin; and carrying out melt extrusion through a double-screw extruder after mixing, and cooling and dicing to obtain the composition of the drip irrigation zone material. According to the composition disclosed by the invention, an appropriate amount of the processing modifier is added into the polyethylene resin, so that the problems that a drip irrigation zone product is difficult to form in a production process, low in production efficiency, poor in outline quality, and the like, are solved; meanwhile, product processing performance is improved, accumulated materials at a neck mould are reduced, product outline quality is improved, and first-pass yield of the product is increased. The composition of the drip irrigation zone material disclosed by the invention has the advantages of being good in processing performance, attractive in appearance, excellent in ageing resistance and the like, is widely applied to the industries such as agriculture, forestry and city greening, and has a wide scope of application and economic benefits.

Description

technical field [0001] The invention relates to a drip irrigation belt material composition, which belongs to the field of polymer processing. Background technique [0002] my country is a country that is not rich in water resources. Among all water-using departments, agricultural irrigation water is the most, accounting for about 80% of the total water consumption in the country. The contradiction has very important strategic significance. Therefore, in recent years, a series of water-saving equipment such as sprinkler irrigation, micro-irrigation, and under-film drip irrigation have been developed successively. Among them, drip irrigation is the most effective water-saving irrigation method in arid and water-scarce areas, and its water utilization rate can reach 95%. Compared with sprinkler irrigation, drip irrigation has a higher effect of saving water and increasing production. At the same time, it can be combined with fertilization to improve fertilizer efficiency. It ...
