Problems solved by technology

The agricultural film produced in this way is not easy to control due to poor control of the spraying technology, and the products produced are prone to uneven coating liquid, and the function of dripping and defogging cannot be guaranteed, which affects the use effect; at the same time, due to discontinuous production, resulting in Massive consumption of manpower and material resources

Embodiment 1

[0031] The one-step method of externally-coated inorganic nanometer water-soluble dripping anti-fog liquid is used to produce long-term dripping anti-fog heat preservation and anti-aging film. The production steps are as follows:

[0032] The first step: Mix 15Kg of light stabilizer and antioxidant with 90Kg polyethylene resin, and make an anti-aging masterbatch through a twin-screw extruder; pass 50Kg of hydrotalcite and 80Kg polyethylene resin through an internal mixer and a single screw The extruder makes hydrotalcite insulation masterbatch.

[0033] Step 2: Mix 200Kg LLPE 2045 and about 20Kg anti-aging masterbatch evenly, and then add them to the inner and outer layer feeding ports of the three-layer co-extrusion blown film unit; mix 100Kg mLPE 2005, 100Kg mLPE 2010, 20Kg insulation masterbatch is evenly mixed and then added to the middle feeding port of the three-layer co-extrusion film blowing unit. A tubular film is made by a three-layer co-extrusion blown film unit, c...

Embodiment 2

[0035] Embodiment 2, using the one-step method of externally coated inorganic nanometer water-soluble dripping anti-fog liquid to produce long-term dripping anti-fog heat preservation and anti-aging film, the production process is as follows:

[0036] The first step: mix 10Kg of light stabilizer and antioxidant with 85Kg polyethylene resin, and make an anti-aging masterbatch through a twin-screw extruder; pass 20Kg of hydrotalcite and 50Kg polyethylene resin through an internal mixer and a single screw The extruder makes hydrotalcite insulation masterbatch.

[0037] Step 2: Mix 200Kg of mLLPE 2010 and about 20Kg of anti-aging masterbatch evenly and add them to the inner and outer layer feeding ports of the three-layer co-extrusion film blowing unit; mix 100Kg of mLLPE2005, 100Kg of LLPE 2045 and 15Kg of anti-aging masterbatch Materials, 25Kg insulation masterbatch are evenly mixed and then added to the middle feeding port of the three-layer co-extrusion blown film unit. The c...

Abstract

A long-acting dripping fog-dissipating heat-insulating aging-resistant agricultural film produced by externally-coated inorganic nanometer water-soluble dripping fog-dissipating liquid through a one-step method has a continuous service life of 2-5 years. The production process of the film comprises the following steps: well mixing resins, a light stabilizer, and an antioxidant, preparing an aging-resistant master batch by a twin-screw extruder; well mixing the resins and a heat-insulating agent, preparing a heat-insulating master batch by a internal mixer and a single-screw extruder; well mixing the resins, the aging-resistant master batch, and the heat-insulating master batch, blowing to prepare a cylindrical film; clamping the film by an upper drawing roller to obtain a flat film, performing surface treatment of the film by a corona treatment machine, coating the dripping fog-dissipating liquid on the film in a liquid-coating device, performing homogenization and drying, rolling to prepare the long-acting dripping fog-dissipating heat-insulating aging-resistant film.

Description

technical field [0001] The present invention relates to agricultural plastic films. Specifically, in the process of multi-layer co-extrusion blown polyolefin aging-resistant film, an inorganic nano water-soluble glue is coated on the outer surface of the film, and after coating, homogenization, drying, cooling, flattening, and shrinkage Through the rolling step, an agricultural film with high transparency, high strength, high heat preservation and the function of dripping and defogging that is synchronized with the service life of the film is obtained. Background technique [0002] my country has been producing agricultural plastic films since the early 1960s, which are mainly used for covering greenhouses. It is generally divided into ordinary shed film and functional film (aging resistance). With the continuous improvement of greenhouse production technology, drip insulation and anti-aging films have developed rapidly. Due to the large temperature difference between the...
