Problems solved by technology

[0011] In the process of using the agricultural film containing the above-mentioned dripping agent, it is found that although the anti-dripping effect of this agricultural film can last for 5-6 months, the connection between the early, middle and late stages is very poor, and anti-flow sometimes occurs in the middle During the period of outage, the anti-dripping effect of the agricultural film is very poor, so it is necessary to provide an agricultural film dripping agent with good anti-dripping effect in the early, middle and late stages

Embodiment 1

[0036] refer to figure 1 , a preparation process of dripping agent for agricultural film, comprising the steps of:

[0037] S1: preparing the first raw material. First, 15 parts by weight of octadecyl primary amine were put into the reactor, and the reactor was evacuated. Then, the temperature in the reactor was raised to 150° C., and then ethylene oxide was added dropwise into the reactor, and the amount of ethylene oxide dropped was 3.5 parts by weight. While adding ethylene oxide dropwise, the temperature in the reactor starts to rise, and it is raised to 160°C for heat preservation, and the heat preservation is continued until the addition of ethylene oxide is completed. After the dropwise addition, the materials in the reactor are Stirring is continued for 15 minutes, and then the material is discharged, thereby obtaining the first raw material.

[0038]S2: preparing a second raw material. First put 6.5 parts by weight of polyethylene glycol into the reactor, and vacu...

Abstract

The invention relates to the technical field of agricultural film auxiliaries, and discloses an agricultural film dripping agent. The agricultural film dripping agent is prepared from the following substances in parts by weight: 10-20 parts of octadecyl primary amine, 2-5 parts of ethylene oxide, 3-6 parts of stearic acid, 4-9 parts of polyethylene glycol, 30-50 parts of glyceryl monostearate, 4-9parts of castor oil polyoxyethylene ether, 6-15 parts of polyglycerol ester, 8-15 parts of sorbitan monostearate and 9-17 parts of sorbitan monostearate. According to the dripping agent, after the dripping agent is used in the agricultural film, the dripping prevention effect cohesiveness in the initial stage, the middle stage and the later stage is good and the situation of interruption is avoided.

Description

technical field [0001] The invention relates to the technical field of agricultural film additives, more specifically, it relates to an agricultural film dripping agent and a preparation process thereof. Background technique [0002] Plastic agricultural films are mostly hydrophobic substances. When the surface temperature of the plastic film reaches below the dew point, when the water vapor in the air reaches saturation or supersaturation, it will condense into water droplets on the surface and atomize. The existence of fog droplets will cause light scattering or reflection, which directly affects the light transmittance of agricultural or horticultural greenhouse films and affects the growth of greenhouse plants. If the water droplets drop directly from the agricultural film on the crops, the leaves, cores or root mold of the crops will be damaged. Due to the temperature difference between the inside and outside of the agricultural film, the water vapor in the air cools a...
