Strawberry dual-proof polyethylene agricultural greenhouse film

Abstract

The invention discloses a strawberry dual-proof polyethylene agricultural greenhouse film. The strawberry dual-proof polyethylene agricultural greenhouse film comprises the following raw materials in parts by weight: 15-20 parts of vinyl acetate copolymer base material, 18-22 parts of high-density polyethylene base material, 15-20 parts of linear polyethylene base material, 10-15 parts of linear low-density polyethylene base material, 15-20 parts of metallocene polyethylene resin base material, 18-22 parts of sorbitan monolaurate, 1-3 parts of polyethylene wax, 0.05-0.15 part of antioxidant, 0.2-0.4 part of anti-oxygen agent, 0.01-0.015 part of ultraviolet absorption agent and 0.001-0.002 part of agricultural film color concentrate pigment. A preparation method comprises the following steps: mixing the raw materials, completing heating, then simultaneously feeding by three extruding machines, extruding into a machine head for discharge, cooling the discharged material with cooling wind, further performing secondary traction to primary traction, and finally winding and packaging to form a finished product. The effective service life of the agricultural greenhouse film produced by the method disclosed by the invention can achieve 3 years, and the antifog effective period can be prolonged to above 6 months; the tensile strength and the puncture strength are improved by 15%; and by using the product, the production of strawberry crops can be increased by 20%.

Description

technical field [0001] The invention relates to a shed film, in particular to a strawberry double-proof polyethylene agricultural shed film. Background technique [0002] Strawberry is also called cranberry, raspberry, ground berry, etc. It is a kind of red fruit. Strawberry is a general term for plants of the genus Fragaria in the Rosaceae family, which belongs to perennial herbaceous plants. Strawberries are heart-shaped in appearance, delicious, red and tender, with juicy pulp and a special rich fruit aroma.

AI Technical Summary

Problems solved by technology

[0003] The existing shed film erected in strawberry planting mainly adopts polyethylene agricultural film, which is made of ordinary polyethylene resin as raw material. In the production of strawberries, the increase in production or the impact on strawberry planting has not been considered. Provide the benefits of quality, etc. The existing agricultural film has a single function and is easy to age. After forming fog droplets on the shed film, water drips, which has a great impact on strawberry production, and the strength is not enough.
