Mother material for preparing eggplant greenhouse film and with photoconversion function

Abstract

The invention belongs to the technical field of chemical synthesis, and in particular relates to a mother material for preparing an eggplant greenhouse film and with a photoconversion function. The mother material is prepared from the following raw materials in percentage by weight: 85 percent of a main body material, 3 to 5 percent of rare earth metal oxide, 5 to 6 percent of silicon dioxide, 2 to 5 percent of an impact modifier and 1 to 2 percent of an antioxidant, wherein the main body material is one or more of LDPE, LLPE, PP, EVA, mLDPE and POE. The mother material can effectively convert harmful ultraviolet light in sunlight into infrared light beneficial for eggplant crops, so that the yield of the eggplants is increased, the quality of the eggplants is improved, the economic crops come into the market in advance, and the growth cycle is shortened.

Description

technical field [0001] The invention belongs to the technical field of chemical synthesis, and in particular relates to a masterbatch with light conversion function for preparing eggplant greenhouse films. 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 agricultu...

Problems solved by technology

[0003] As we all know, the ultraviolet light in sunlight is harmful to plants, how to convert these unfavorable ultraviolet light into other absorbable light is also a problem to be solved; patent application number: 201210126630.4 mentions a process , but this process is all a kind of thinking, adding rare earth metal conversion agent, but the specific dosage is not mentioned, just a brief description of a preparation process, and the preparation process, the preparation process of the masterbatch is similar, the difference is not big , can not bring about substantive changes

[0004] In addition, there are currently some patents that also mention this concept, which is light conversion film, but most of them are aimed at common plants. There is no patent that can study and penetrate specific plants, such as eggplant. The current greenhouse planting is large-scale and unified. Generally, planting a certain kind of plant is to fix which one, and each plant has its own characteristics. If it is aimed at general plants, then the effect is definitely not as good as targeting only one plant.
