Problems solved by technology

Adding a light conversion agent to the agricultural film can effectively improve the light conversion efficiency. At present, the light conversion agent is divided into two types: inorganic light conversion agent and organic light conversion agent. The former has a long duration, but the light conversion efficiency is low; the latter light conversion efficiency high, but short half-life

[0025] Coupling agent 0.1-0.3g

[0026] Antistatic agent 0.1-0.2g

[0027] Silica sol 7-12g

[0028] Titanium dioxide sol 7-12g

[0029] Distilled water 200-1000g

[0030] First dissolve the titanium dioxide sol into the distilled water, and stir evenly; then dissolve the silica sol into the aforementioned solution, and stir evenly; dissolve the coupling agent and antistatic agent into the aforementioned solution, stir evenly, and then inject the compounded solution into the In the stainless steel container, use a high-pressure pump with a pressure ≥ 8 MP to inject into the rotary splitter through precise metering; spray in the film bubble through a...

Embodiment 2

[0031] Embodiment 2: Produce 7 meters wide 0.08mm thick with three-layer blow molding agricultural film unit, the outer layer prepares surface light-grafted film shed film:

[0032] Common blown film processes are known. According to the anti-aging formula:

[0033] Polyethylene film 100m 2

[0034] Cationic surfactant 0.1-0.3g

[0035] Acrylic microemulsion 1-2g

[0036] Photosensitizer 0.1-0.3g

[0037] Silica sol 7-12g

[0038] Titanium dioxide sol 7-12g

[0039] Distilled water 200-1000g

Then inject the compounded solution into the stainless steel barrel, and use a liquid pump with a pressure ≥ 10MP to inject it into the fixed splitter through precise metering; sp...

Embodiment 3

[0041] Embodiment 3: with the rolled blown film that has been sprayed, double-layer prepares blown film photocatalyst interface molecular film:

[0042] Get the photografted polyethylene film sprayed through example 2:

[0043] Polyethylene film 100m 2

[0044] Antistatic agent 0.1-0.3g

[0045] Silica sol 7-12g

[0046] Distilled water 200-1000g

[0047] Stir the silica sol with distilled water first, then compound the antistatic agent together and stir evenly. Then inject the prepared liquid into a liquid tank; place the single roll of film that has been made on the driven roller to release the film, and put the photografted film into the liquid tank through the unrolling device for soaking treatment, so that the light The surface layer of the grafted polyethylene film is dip-coated with an antistatic coating; then the film is introduced into the dryer through a guide roller, and the finished product is made by a winding or folding device. While possessing the film eff...

Abstract

The present invention discloses a light-enforcing agricultural greenhouse membrane and a production process thereof, belonging to the chemical industry. The light-enforcing agricultural greenhouse membrane comprises polyolefin membrane and optical-efficiency self-assembling hybrid membrane. The greenhouse membrane is characterized in that the formula of the optical-efficiency self-assembling hybrid membrane comprises one of or a plurality of dioxide titanium sol with a particle size less than or equal to 20nm and colloidal solid content less than or equal to 30 percent, silica dioxide sol witha particle size less than or equal to 10nm and colloidal solid content less than or equal to 30 percent, distilled water, acrylate micro-emulsion with particle size less than or equal to 100nm, photosensitizer, coupling agent, cationic surfactant, antistatic agent. The polyolefin membrane material of each 10,000 m<2> needs 20kg to 160kg of optical-efficiency self-assembling hybrid membrane. Withthe formula of the optical-efficiency self-assembling hybrid membrane, an optical-efficiency self-assembling hybrid membrane can be prepared on the surface in the molding process of polyolefin membrane.The light-enforcing agricultural greenhouse membrane of a plurality of effects can be prepared.

Description

technical field [0001] The invention relates to a light synergistic agricultural greenhouse film and a production process thereof, in particular to a method for preparing an extremely thin light synergistic self-assembled hybrid film on the surface layer of a polyolefin film, which belongs to the field of chemical industry. Background technique [0002] The dripping and anti-fog lasting effect of agricultural greenhouse film is the main bottleneck restricting the function and synchronization of agricultural film. At present, the dripping and defogging properties in China are mainly provided by additive-type fogging agents and defogging agents, so that the greenhouse has good light transmission and heating conditions. However, the additive additives have a short duration of effect, and the best domestic products can only reach the effect of two years. In the first year of use, due to a large amount of precipitation of dripping agent, the haze of the shed film increases, and ...
