Abstract

The invention relates to a grafting method permanent fog dispersal and dripping agricultural film and a preparation method thereof and belongs to the technical field of agricultural plastic films. The agricultural film comprises an inner layer, a middle layer and an outer layer. The inner layer is prepared from EVA, LDPE, grafting master batch and anti-aging master batch. The middle layer is prepared from EVA, mLLDPE, LDPE and anti-aging master batch. The outer layer is prepared from mLLDPE, LDPE and anti-aging master batch. The grafting master batch is prepared from EVA, an initiator, acrylic acid, a dripping agent and a fog dispersal agent. The preparation method includes the steps that the raw materials of the inner layer, the raw materials of the middle layer and the raw materials of the outer layer are added into mixers respectively to be mixed according to the formula ratio, then the mixed raw materials are sequentially added into hoppers to be extruded, and the grafting method permanent fog dispersal and dripping film is obtained after film blowing, upward traction, roller guiding, lower traction, winding, metering and weighing. The grafting method fog dispersal and dripping agricultural film has the effect that the fog dispersal and dripping function and the service life of the agricultural film are synchronous, the preparation method is simple, equipment investment is little, and operation is convenient.

Description

technical field [0001] The invention relates to a permanent anti-fog and dripping agricultural film by grafting method and a preparation method thereof, belonging to the technical field of agricultural plastic films. Background technique [0002] Agricultural greenhouse film is one of the important covering materials for horticultural facilities, and its function of eliminating fog and dripping is particularly important to whether it can meet the needs of plant growth. At present, most of the agricultural greenhouse films produced by agricultural film enterprises in my country adopt two production processes: one is the internal addition method of polyethylene / EVA anti-fog dripping film, that is, the small molecular weight dripping agent and anti-fogging agent are passed through the masterbatch method. Added into the greenhouse film, the dripping agent and anti-fogging agent are surfactants, which will migrate to the surface of the film in a short time. Due to the generation o...
