Polychloroethylene fruit tree special-purpose membrane

Abstract

The invention relates to agricultural polyvinyl chloride shed film exclusively used for the fruit trees, which can adjust the transmitted spectrum of the sunlight in the greenhouse, promote the photosynthesis of the fruit trees, and improve the fruit quality and output. Polyvinyl chloride resin is taken as the basal body of the agricultural polyvinyl chloride shed film exclusively used for the fruit trees, plasticizer, heat stabilizer, ultraviolet absorber, compound dripless agent, organosilicon antifogging agent, hindered amine light stabilizer and light conversion agent, etc. are added in the basal body, and then the agricultural polyvinyl chloride shed film exclusively used for the fruit trees is prepared through the production process steps of reducing and tentering, etc. The invention can overcome the deficiency that the polyvinyl chloride film is produced by utilizing the ultraviolet absorber as the light stabilizer, during the novel polyvinyl chloride function film production, a method that the hindered amine light stabilizer and the light conversion agent with reasonable compounding ratio are added is adopted, to ensure that the light transmittance of the film is improved in a certain wavelength range, to play the effect on promoting the fruit coloring of the fruit tree in the shed.

Description

technical field [0001] The invention relates to an agricultural shed film and a manufacturing method thereof, in particular to an agricultural polyvinyl chloride special shed film for fruit trees that can adjust the transmission spectrum in a greenhouse of sunlight, promote photosynthesis of fruit trees, and improve fruit quality and yield . Background technique [0002] The importance of light to plant photosynthesis is undeniable, but not all bands of light in the solar spectrum are beneficial to plant growth. The effect of light on plants is closely related to the composition of the solar spectrum. Plants can only work in their specific optimal spectrum. environment to grow healthily. [0003] At present, most of the domestically produced PVC agricultural shed films use ultraviolet absorbers as light stabilizers. Since the ultraviolet absorbers absorb 290nm-400nm ultraviolet light when sunlight passes through, this part of the light entering the greenhouse through the fi...

Problems solved by technology

[0003] At present, most of the domestically produced PVC agricultural shed films use ultraviolet absorbers as light stabilizers. Since the ultraviolet absorbers absorb 290nm-400nm ultraviolet light when sunlight passes through, this part of the light entering the greenhouse through the film is reduced. , when this kind of shed film is used to cover the greenhouse, the fruits of the fruit trees in the shed will be slowly colored, unevenly colored, and of poor quality, which will affect the sales price
