Abstract

The invention relates to the technical field of garden drainage, and provides a green drain pipe for a municipal garden for the problem of easy embrittlement and cracking of polypropylene. According to the technical scheme, the drain pipe is prepared from a drain pipe composition, wherein the drain pipe composition is prepared from, by mass, 100 parts of polypropylene, 10-15 parts of urea formaldehyde, 33-44 parts of polyacrylonitrile and 15-22 parts of cellulose acetate. The polyacrylonitrile, the cellulose acetate and the urea formaldehyde are added into the polypropylene, and mixing is carried out in a specific proportion, which effectively improves the low temperature resistance of the drain pipe composition, so that the drain pipe composition is better applied to cold regions, and theapplicability of the prepared drain pipe is wider.

Description

technical field [0001] The invention relates to the technical field of garden drainage, in particular to a green drainage pipe for municipal gardens. Background technique [0002] In order to maintain the growth of green plants in the municipal garden landscape, it is necessary to regularly irrigate the green plants to maintain the water required by the green plants. At the same time, the municipal garden landscape is usually an open-air facility. When it rains, the rain falls in the soil and on the road, which needs to be discharged in time. Otherwise, it is easy to form stagnant water, so it is necessary to use a drainpipe for drainage. [0003] Generally, the drainage pipe needs to be buried underground, otherwise it will affect the appearance. Therefore, the drainage pipe needs to have good corrosion resistance. Usually, the drainage pipe will be made of polypropylene to take advantage of the weather resistance and chemical corrosion resistance of polypropylene. Better ...
