Problems solved by technology

Directly using ordinary green color masterbatch to add and produce green shed film has the following disadvantages in the actual planting application of ginger: first, the color of the film is easy to fade with the prolongation of use time, and the growth light environment that is beneficial to the growth of ginger cannot be maintained in the later stage; The second is that the different shades of the color have different effects on the final yield of ginger. The increase or decrease in the amount of anti-aging green masterbatch alone cannot meet the needs of ginger for the quality of transmitted light. Improper selection of color masterbatch will cause ginger Production reduction; at the same time, after the existing ordinary green masterbatch is added to the shed film material, due to the components, the strength of the shed film will often be reduced, and the weather resistance will also be reduced, which will seriously affect the production of ginger.

Abstract

The invention belongs to the field of materials, relates to an anti-ageing dimming color master batch for plastics and in particular relates to a special anti-ageing dimming green master batch for a ginger greenhouse film and a preparation method of the special anti-ageing dimming green master batch. The special anti-ageing dimming green master batch is prepared by the following steps: using pigments, a light stabilizer and an antioxidant which are specially selected, loading on a sustained-release agent, and obtaining the special anti-ageing dimming color master batch for ginger cultivation with a carrier resin as a matrix. The special greenhouse film prepared by adding the special anti-ageing dimming green master batch is difficult in color fading and good in anti-ageing performance and is capable of providing light environment needed by a growth development period of gingers, facilitating growth and development of the gingers and remarkably increasing the yield of ginger.

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 green masterbatch for ginger shed film and a preparation method thereof. Background technique [0002] Ginger is the fresh rhizome of ginger, a perennial herb of the Zingiberaceae family, and is a widely planted crop in my country. In traditional Chinese medicine, ginger has the effects of divergence, vomiting, and cough relief. It is also a commonly used condiment in food processing and daily life in my country. [0003] Ginger likes temperature and is not resistant to strong light. Generally, it is cultivated in sloping and slightly shaded plots. However, in order to expand the planting area, it is generally cultivated with plastic film or shed film. Ordinary transparent shed film has higher light transmittance. Studies have shown that changing and adjusting the light transmittance and anti-aging gre...
