Abstract

The invention relates to a production technology of a special water dropper for preventing a root system from being invaded by subsurface drop irrigation, comprising the following steps: (1) evenly mixing high pressure polyethylene, N-di-propyl-4-trifluoromet, antioxidant aging agent and biological aging inhibitor to obtain a mixture; (2) successfully heating, plasticizing, extruding, shaping, cooling, granulating and drying the mixture, and preparing into root-removal anti-aging master batch; and (3) after the root-removal anti-aging master batch obtained in step (2) is evenly mixed with injection-class low pressure polyethylene and master batch, heating, plasticizing, closing mould, injecting, pressurizing, cooling and shaping to obtain the finished product. The method of the invention can ensure that a functional auxiliary material with small content is evenly and integrally mixed, and plasticizing dispersing evenness in the injection process of the finished product is obviously improved; and meanwhile, the method can effectively improve the heat resistance, the aging resistance and the corrosion resistance of the finished product.

Description

technical field [0001] The invention relates to the technical field of drip irrigation products, in particular to a production method of a special dripper for underground drip irrigation to prevent root invasion. Background technique [0002] Plant root invasion is one of the important reasons for the clogging of underground drip irrigation emitters, which directly affects the normal operation and promotion of the underground drip irrigation system. Many experts at home and abroad have researched and discussed this problem, and put forward some methods and measures to solve this problem, including changing the process to produce special drippers for underground drip irrigation to prevent root invasion. head, but its production process is complicated and the cost is too high, so it has not been widely used. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production method of a special dripper for underground dr...
