Problems solved by technology

[0006] However, the direct use of common red color masterbatch as auxiliary agent to produce shed film has the following disadvantages: the first is that the color masterbatch is easy to decompose under strong light, causing the shed film to fade quickly; The effect on the formation of functional pigments is also different. Simply using the increase or decrease in the amount of red masterbatch cannot meet the requirements for the formation of functional pigments in solanaceous vegetables and the conversion of active enzymes

Abstract

The invention belongs to the field of materials, and particularly relates to a special anti-ageing dimming red masterbatch for a solanaceous fruit vegetable greenhouse film and a preparation method of the anti-ageing dimming red masterbatch. The special anti-ageing dimming red masterbatch for the solanaceous fruit vegetable greenhouse film is obtained by especially selecting a red pigment, loading a light stabilizer and an antioxidant on a sustained-release agent, and adopting carrier resin as matrix. The special greenhouse film prepared by adding the masterbatch is not easy to fade, long in service life and moderate in light transmittance; red and orange light and far-red light of the transmitted spectrum are increased; and the nutrient quality of the solanaceous fruit vegetables can be obviously improved.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a plastic masterbatch, in particular to a special anti-aging and dimming red masterbatch for solanaceous vegetable shed film. Background technique [0002] Plant lycopene and anthocyanin are natural functional pigments, safe, non-toxic, and have strong antioxidant capacity. They have significant effects on preventing cancer and cardiovascular and cerebrovascular diseases, improving human immunity, and delaying aging. It has broad application prospects in additives, cosmetics, food coloring and other fields. [0003] Lycopene mainly exists in tomato and other crops. In addition to being used to make tomato paste and tomato juice, lycopene in tomato is also widely used in industries such as food additives, pharmaceutical raw materials and advanced cosmetics. In recent years, blueberries rich in anthocyanins have been favored by the food and health care product industries. They...
