Problems solved by technology

However, the embrittlement temperature of polypropylene pipe is high, the size shrinkage series is large, and it is especially sensitive to low temperature. As the temperature decreases, the mechanical properties decrease significantly, thus limiting its application range.
In addition, its aging resistance is also poor

Abstract

The invention discloses a modified polypropylene (PP) spray irrigation tube which is characterized by comprising the following raw materials in parts by weight: 80-120 parts of PP, 0.2-0.8 part of antioxidant 1246, 10-20 parts of LDPE (low-density polyethylene), 0.2-0.8 part of high-pigment carbon black, 10-20 parts of high cis-1,4-polybutadiene rubber, 0.2-0.8 part of sodium benzoate and 0.2-0.4 part of UV-327.Compared with the prior art, the modified PP spray irrigation tube has the advantages of low product price, low raw material consumption, simple production technique, high strength, favorable low-temperature resistance, favorable aging resistance and the like.

Description

technical field [0001] The invention relates to the field of material science, in particular to a modified polypropylene spray irrigation pipe. Background technique [0002] Polypropylene sprinkler pipes are used for agricultural irrigation. They are generally mobile or semi-mobile. They are required to withstand pressure and impact loads of 3.4-0.6WPa, and can withstand bending and tensile stress. They have certain toughness and rigidity and low temperature resistance. , Can bear the alternating action of cold and heat and anti-aging, and the quality should be light to facilitate installation and movement. Compared with rigid polyvinyl chloride pipes, polypropylene pipes have the advantages of light weight, good heat resistance, good bendability, non-toxicity and saving pipe joints. Therefore, modified polypropylene is selected and a certain amount of antioxidant is added and UV absorbers to produce sprinkler irrigation pipes. The biggest feature of polypropylene pipe is ...
