Embodiment 2

[0012] Example 2, the process flow is: weighing according to the formula, PVCSG-3 type: 58.9kg; DOP: 15kg; GZ: 5kg; P83: 0.5kg; carbon black: 0.5kg; CPE: 5kg; ACR-401: 2kg; DOTTG: 2.5kg; aluminate coupling agent: 0.6kg; light CaCO 3 : 10kg; Put it into a high-speed mixer, rely on friction to heat it up to 110-120 ° C, high-speed kneading and discharge to low-speed cold stirring, cool to 45 ° C, discharge, and set aside. Start the twin-screw granulator and heat up to 160 ~ At 180°C, add the above-mentioned mixed powder into a granulator to granulate, and set aside. Raise the temperature of the main machine of the drip irrigation belt to 160-195°C, add the above-mentioned prepared pellets, plasticize, filter and extrude to form a polyvinyl chloride (PVC) drip irrigation belt.

Embodiment 3

[0013] Example 3, the process flow is: PVCSG-3 type: 56.8kg; DOP: 20kg; GZ: 5kg; stearic acid: 1kg; XT: 0.5kg; carbon black: 1kg; EVA: 4kg; ACR-401: 3kg; DBTI: 1.5kg; titanate coupling agent: 0.8kg; put it into a high-speed mixer, rely on friction to raise the temperature to 110-120°C, high-speed kneading and discharge to low-speed cold stirring, and discharge after cooling to 45°C for later use .Start the twin-screw granulator, heat up to 160-180°C, add the above-mentioned mixed powder into the granulator to granulate, and set aside. Raise the temperature of the main machine of the drip irrigation belt to 160-195°C, add the above-mentioned prepared pellets, plasticize, filter and extrude to form a polyvinyl chloride (PVC) drip irrigation belt.

Embodiment 4

[0014] Embodiment 4, the technological process is: PVCSG-4 type: 56.5kg; DOP: 15kg; GZ: 15kg; carbon black: 1.5kg; MBS: 4kg; ACR-401: 1kg; XT: 0.5kg; DBTM: 1kg; titanium Ester coupling agent: 0.4kg; Nano CaCO 35kg; Put it into a high-speed mixer, rely on friction to heat it up to 110-120°C, high-speed kneading and discharge to low-speed cold stirring, cool to 45°C, discharge, and set aside. Start the twin-screw granulator and heat up to 160-180 ℃, add the above-mentioned mixed powder into the granulator to granulate, set aside. Raise the temperature of the main machine of the drip irrigation belt to 160-195°C, add the above-mentioned prepared pellets, plasticize, filter and extrude to form a polyvinyl chloride (PVC) drip irrigation belt.

Abstract

The invention relates to a modified polyvinyl chloride (PVC) drip tape applied to the filed of agricultural water-saving irrigation facilities. The formula of the PVC drip tape comprises carbon black, a plasticizer, a high molecular plasticizer (GZ), an anti-impact modifier, a lubricant, a processing accessory agent, a heat stabilizer, calcium carbonate (CaCO3), a coupler and PVC; the carbon black comprises medium color black and common color black; the PVC comprises the types of PVC-SG2, PVC-SG3, PVC-SG4 and PVC-SG5; the plasticizer comprises dibutyl phthalate (DBP) and dioctyl sebacate (DOS); the lubricant comprises a compound lubricant, i.e., a stearic acid, calcium stearate, chlorinated paraffin or oxidized polyethylene wax (OPE). The modified PVC drip tape has scientific and novel conception; the PVC drip tape has excellent comprehensive performance after modification treatment by using various modification accessory agents; and compared with the common PVC drip tape, the modified PVC drip tape has relatively low production cost and more remarkable advantages in price and performance, can reduce the consumption of gasoline resource and is more beneficial to the agricultural water-saving irrigation technology of China.

Description

Technical field: [0001] The invention relates to a modified polyvinyl chloride (PVC) drip irrigation belt in the field of agricultural water-saving irrigation facilities. Background technique: [0002] The problem of water resource scarcity in China has been put on the agenda. How to solve the problem of water resource shortage in China has become a topic of increasing concern to national leaders and experts. National leaders have repeatedly proposed: the problem of water resources should be tackled as a problem of the whole society . In the case of limited total available water resources, water saving will be the only means and measures to solve the problem of water shortage in China. "Water conservation should be taken as a revolutionary measure" is a top-down appeal. Since China's agriculture is a large water user, agricultural water conservation will be the first problem to be solved. [0003] The country has taken agricultural water-saving irrigation as an important c...
