Drop irrigation belt and preparation method thereof

Abstract

Disclosed is a drip irrigation tape and process for preparation. The drip irrigation tape comprises the following raw materials: HHMTR144 resin, black masterbatch and polyester of 1.2 -propylene adipate. The process for preparation is that the needed raw materials content is fully commingled in a mixer, and then is transported to the production line of a single screw rod extractor to extrude moulding and obtain the drip irrigation tape. The invention has the advantages that the processing property, the appearance quality and the productive efficiency of the drip irrigation tape are improved, accumulated material phenomenon of die orifice is reduced or is eliminated, the surface pit of the drip irrigation tape is eliminated, the process temperature is decreased, electric power consumption is reduced, thereby energy is saved, through improving the processing property, the one time qualified rate of product and the yield are increased, thereby the manufacturing cost of the drip irrigation tape is low, simultaneously, the decayed hole arisen in the process of production with the drip irrigation tape is reduced, the phenomenon of chronic machine halt in the process of production is avoided, thereby the process of production is easily controlled, using the drip irrigation tape of the invention facilitates crop growth, thereby economic loss is reduced.

Description

1. Technical field: [0001] The invention relates to the technical field of drip irrigation tape, and relates to a drip irrigation tape and a preparation method thereof. 2. Background technology: [0002] Because drip irrigation technology has the characteristics of water saving, labor saving, and easy management, it is widely used in crop production, especially in the cultivation of economic crops. However, most of the drip irrigation belts currently on the market and used in production do not add processing aids. The surface of the produced product is generally rough, and the friction of the die mouth is large during extrusion, which is easy to cause the phenomenon of material accumulation at the die mouth. At the same time, due to the many defects of the drip irrigation belt, it is easy to form air bubbles and cause rotten holes, which brings great inconvenience to production. , causing the production cost of the drip irrigation belt to increase, and if the products obtain...

Problems solved by technology

[0002] Because drip irrigation technology has the characteristics of water saving, labor saving, and easy management, it is widely used in crop production, especially in the cultivation of economic crops. However, most of the drip irrigation belts currently on the market and used in production do not add processing aids. The surface of the produced product is generally rough, and the friction of the die mouth is relatively large during extrusion, which is likely to cause material accumulation at the die mouth. At the same time, due to the many defects of the drip irrigation belt, it is easy to form air bubbles and cause rotten holes, which brings great inconvenience to production. , resulting in an increase in the production cost of drip irrigation belts. At the same time, if the products produced in this way are put into use, it will cause serious losses to crops.
