Embodiment 1

[0022] A masterbatch with light conversion function, made of the following raw materials in weight percentage:

[0023]

[0024] The main body material is LDPE.

[0025] The rare earth metal oxide is cerium oxide.

[0026] The particle size of the rare earth metal oxide is 800 mesh.

[0027] The impact modifier is microcrystalline wax.

[0028] Described antioxidant is B215.

[0029] The usage amount of the masterbatch with light conversion function is 2% of the film mass.

[0030] After preparing the masterbatch, mix LDPE, LLDPE, mLLDPE and the masterbatch. After mixing, extrude and blow the film through the extruder, and then draw and roll after being cooled by the air ring to obtain the finished product.

Embodiment 2

[0032] A masterbatch with light conversion function, made of the following raw materials in weight percentage:

[0033]

[0034] The main material is mLDPE and POE mixed according to the mass ratio of 1:1.

[0035] The rare earth metal oxide is a mixture of cerium oxide and neodymium oxide in a mass ratio of 1:2.

[0036] The particle size of the rare earth metal oxide is 2500 mesh.

[0037] The impact modifier is a mixture of microcrystalline wax, polyethylene wax and EVA wax in a mass ratio of 1:1:1.

[0038] Described antioxidant is 225.

[0039] The amount of the masterbatch with light conversion function is 10% of the mass of the film.

[0040] After preparing the masterbatch, mix LDPE, LLDPE, mLLDPE and the masterbatch. After mixing, extrude and blow the film through the extruder, and then draw and roll after being cooled by the air ring to obtain the finished product.

Embodiment 3

[0042] A kind of described masterbatch with photoconversion function is made of the following raw materials in weight percentage:

[0043]

[0044] The main body material is POE.

[0045] The rare earth metal oxide is yttrium oxide.

[0046] The particle size of the rare earth metal oxide is 1000 mesh.

[0047] The impact modifier is EVA wax.

[0048] Described antioxidant is B215.

[0049] The amount of the masterbatch with photoconversion function is 70% of the mass of the film.

[0050] After preparing the masterbatch, mix LDPE, LLDPE, mLLDPE and the masterbatch. After mixing, extrude and blow the film through the extruder, and then draw and roll after being cooled by the air ring to obtain the finished product.

Abstract

The invention belongs to the technical field of chemical synthesis, and concretely relates to a master batch with a photoconversion function. The master batch with the photoconversion function is prepared from the following raw materials in percentage by weight: 85 to 95 percent of main material(s), 0.5 to 8 percent of rare-earth oxide, 2 to 8 percent of silicon dioxide, 2 to 8 percent of impact modifier, and 0.2 to 1.5 percent of antioxygen, wherein the main material(s) is (are) one or more than one of LDPE (Low-Density Polyethylene), LLPE(Linear Low Density Polyethylene), PP (Propene Polymer), EVA (Ethylene-vinyl Acetate Copolymer), mLDPE and POE (Polyolefin Elastomer). According to the master batch with the photoconversion function provided by the invention, harmful ultraviolet light in sunlight can be effectively converted into infrared light beneficial for vegetable crops, so that the yield and the quality of vegetables are improved, and commercial crops appear on the market in advance.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a masterbatch with photoconversion function. Background technique [0002] Agricultural film is used to cover plastic greenhouses such as solar greenhouses and vegetable greenhouses, which is very common in China. Practice has proved that the application of plastic greenhouse film is one of the most important symbols of the development of agricultural science and technology, and it is an important means to increase agricultural production and income and solve the vegetable basket project. However, as far as my country's current agricultural film technology is concerned, there are still many problems. One of them is that there are few varieties of "functional" agricultural films and their applications are narrow. In Japan and other countries, functional agricultural films emerge in endlessly. The increase of agricultural production, the improvement of benefi...
