Problems solved by technology

[0004] Although the cover film disclosed in this patent has a simple structure and is easy to use, adding a layer of isolation film to the traditional greenhouse film can avoid the large heat dissipation and the temperature inversion phenomenon in the shed, but the cover film does not isolate ultraviolet rays and High and low temperature resistance, can only be used in greenhouses, the scope of use is narrow, and there is no preparation method, therefore, it is necessary to design a plant covering material and its preparation method

Embodiment 1

[0041] The preparation method of the plant covering material comprises the following steps: a, purchasing the raw materials required above; b, adding polyvinyl chloride, dioctyl ester, soybean oil, ultraviolet absorber, anti-cold agent, titanium dioxide, calcium carbonate and water In an ordinary mixer, the stirring speed is 200r / min, and the stirring time is 8min. Stir evenly to prepare a coating liquid; c, pour the coating liquid into the liquid discharge tank 5 of the scraping equipment, and scrape it on the On the two surfaces of the base cloth layer, the coating thickness is 0.15 mm, which is the protective layer; d, the base cloth layer after scraping is ventilated and dried to prepare the plant covering material.

[0042] Such as figure 1 , figure 2 As shown, the scraping equipment in step c includes a frame 1, a liquid discharge tank 5 is fixed on the frame 1, and a liquid discharge tank 5 is fixed on the frame 1 by bolt connection; There is a guide roller 20, and t...

Embodiment 2

[0049] The preparation method of the plant covering material comprises the following steps: a, purchasing the raw materials required above; b, adding polyvinyl chloride, dioctyl ester, soybean oil, ultraviolet absorber, anti-cold agent, titanium dioxide, calcium carbonate and water In an ordinary mixer, the stirring speed is 250r / min, and the stirring time is 12min. Stir evenly to prepare a coating liquid; c, pour the coating liquid into the liquid discharge tank 5 of the scraping equipment, and scrape it on the On the two surfaces of the base cloth layer, the coating thickness is 0.25mm, which is the protective layer; d, the base cloth layer after scraping is ventilated and dried to prepare the plant covering material.

[0050] Such as figure 1 , figure 2 As shown, the scraping equipment in step c includes a frame 1, a liquid discharge tank 5 is fixed on the frame 1, and a liquid discharge tank 5 is fixed on the frame 1 by bolt connection; There is a guide roller 20, and t...

Embodiment 3

[0057] The preparation method of the plant covering material comprises the following steps: a, purchasing the raw materials required above; b, adding polyvinyl chloride, dioctyl ester, soybean oil, ultraviolet absorber, anti-cold agent, titanium dioxide, calcium carbonate and water In an ordinary mixer, the stirring speed is 300r / min, and the stirring time is 15min. Stir evenly to prepare a coating liquid; c, pour the coating liquid into the discharge tank 5 of the scraping equipment, and scrape it on the On the two surfaces of the base cloth layer, the coating thickness is 0.35mm, which is the protective layer; d, the base cloth layer after scraping is ventilated and dried to prepare the plant covering material.

[0058] By adopting the preparation method, the protective layer is firmly fixed on the base cloth layer by scraping, without excessive manual operations, continuous and uninterrupted production can be realized, and the production efficiency is high.

Abstract

The invention provides a plant covering material and a preparation method thereof, and solves the technical problems that an existing covering film does not have the characteristics of isolating ultraviolet rays and resisting high and low temperatures, can be only used in a greenhouse, and is narrow in use range, no preparation method of the existing covering film is provided, and the like. The plant covering material comprises a base cloth layer, wherein protection layers are fixed on the two sides of the base cloth layer and are prepared from the following components in parts by weight: 90 to 100 parts of polyvinyl chloride, 33 to 42 parts of dioctyl phthalate, 2.5 to 3.3 parts of soybean oil, 0.4 to 0.6 part of an ultraviolet ray absorbent, 0.3 to 0.5 part of a cold-proof agent, 10 to 14 parts of titanium dioxide, 5 to 8 parts of calcium carbonate and 35 to 55 parts of water. The preparation method is further provided. The plant covering material has the advantages of wide use range and high production efficiency.

Description

technical field [0001] The invention relates to a covering material, in particular to a plant covering material and a preparation method thereof. Background technique [0002] Plant covering materials are mainly used for planting shed surface covering. There are many types of plant covering materials, all of which must meet the following requirements: good lighting, high airtightness and heat preservation, can be ventilated when necessary, and have strong Excellent toughness and weather resistance and lower cost. Different cultivation methods and uses require covering materials with different characteristics. [0003] After searching, for example, Chinese patent literature discloses a new type of greenhouse covering film [application number: 201320185246.1; announcement number: CN203136655U]. This novel greenhouse covering film is characterized in that the covering film is a plastic film, and an insulating layer is arranged inside it. The insulating layer is made of non-wo...
