Problems solved by technology

Yunnan Province is a large province of flower planting, and the flower industry is developing rapidly. Yunnan Province is located at a high altitude of 1500-2500 meters, with thin atmosphere and strong ultraviolet rays. It is more obvious in the planting of roses, and this section of ultraviolet rays is also a necessary condition for the growth of viruses and winged aphids. Cutting off or weakening this section of ultraviolet rays uses biological means to control flower diseases and insect pests. The existing film for flowers has a blocking effect on ultraviolet rays. Not obvious, the control of pests and diseases depends on pesticides, therefore, it is necessary to propose a special greenhouse film for flowers

Embodiment 1

[0019] A flower-specific shed film, which includes the following raw materials in weight percentages: 20% low-density polyethylene, 50% linear polyethylene, 20% metallocene polyethylene, and 10% functional masterbatch. The shed film is suitable for areas with an altitude of about 1500 meters.

[0020] The functional masterbatch includes the following raw materials in weight percentage: 72% of LD carrier, 1% of antioxidant, 8% of hindered amine light stabilizer, 10% of ultraviolet absorber (benzophenone), 3% of heat preservation agent, Dispersant 6%.

[0021] The preparation method of the above-mentioned functional masterbatch is as follows: mix the raw materials according to the formula, mix them in a high-speed mixer for 1 minute, and then mix them at a low speed for 3 minutes. Drying and granulation process for granulation, the extrusion temperature is 130-185 ℃.

[0023] 1) Mixi...

Embodiment 2

[0028] A flower-specific shed film, said flower-specific shed film comprising the following raw materials in weight percent: 20% low-density polyethylene, 40% linear polyethylene, 30% metallocene polyethylene, and 10% functional masterbatch.

[0029] The functional masterbatch includes the following raw materials in weight percentage: LD carrier 72%, antioxidant 1%, hindered amine light stabilizer 8%, ultraviolet absorber (benzotriazoles) 10%, heat preservation agent 3%, Dispersant 6%.

[0030] The preparation method of the functional masterbatch and the special greenhouse film for flowers are the same as in Example 1. The shed film is suitable for areas with an altitude of about 2000 meters.

Embodiment 3

[0032] A flower-specific shed film, said flower-specific shed film comprising the following raw materials in weight percentage: 20% low-density polyethylene, 30% linear polyethylene, 40% metallocene polyethylene, and 10% functional masterbatch.

Abstract

The invention relates to a special greenhouse film for flowers and plants, and a preparation method thereof, and belongs to the technical field of agricultural films. The special greenhouse film for flowers and plants comprises, by weight:,20-30% of low density polyethylene, 50-60% of linear polyethylene, 10-20% of metallocene polyethylene, and 10-15% of a functional master batch, wherein the functional master batch comprises, by weight, 60-75% of an LD carrier, 1-2% of an antioxidant, 8-10% of a hindered amine light stabilizer, 10-20% of an ultraviolet light absorber, 2-5% of a heat preservation agent and 5-6% of a dispersing agent. On the basis of a polyethylene material, the functional master batch is added, and through the reasonable proportioning of the antioxidant, the hindered amine light stabilizer and the ultraviolet light absorber, the prepared greenhouse film has the advantages that the ultraviolet blocking strength is increased, the tensile strength is high, the aging resistance is good, the heat preservation effect is outstanding, and the service life is long; and the greenhouse film blocks most ultraviolet rays, the problem that red rose petals become black and inundation of pests in the ultraviolet wave band in a visible area are effectively prevented, the yield of crops is increased, and pollution caused by pesticides is reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural films, and in particular relates to a special greenhouse film for flowers and a preparation method thereof. Background technique [0002] The use of greenhouse film is widely used in agricultural planting. The greenhouse film used for planting crop fruits has good light transmission and high transparency, which can promote plant photosynthesis and increase production and income. Yunnan Province is a large province of flower planting, and the flower industry is developing rapidly. Yunnan Province is located at a high altitude of 1500-2500 meters, with thin atmosphere and strong ultraviolet rays. It is more obvious in the planting of roses, and this section of ultraviolet rays is also a necessary condition for the growth of viruses and winged aphids. Cut off or weaken this section of ultraviolet rays and use biological means to control flower diseases and insect pests. The existing film for flo...
