Problems solved by technology

The current vegetable greenhouse film is usually a single-layer design. Due to sunlight or the respiration of the plant itself, a large amount of water vapor will be generated. Because of the good airtightness of this vegetable greenhouse, water vapor cannot leak out, which will cause the inside of the greenhouse to be stuffy. , it will also condense after cooling down, seriously affecting the temperature and humidity environment inside the greenhouse and affecting the light

Abstract

The invention discloses a greenhouse film for gardening and a preparation method thereof. The greenhouse film is prepared from the following raw materials: PET (Polyethylene Terephthalate), PVC (Polyvinyl Chloride), LDPE (Low-Density Polyethylene), polyvinyl alcohol, talcum powder, an antioxidant, an ultraviolet absorbent, polyester fiber, glass fiber, polybutylene succinate, calcium benzoate, polyethylene wax, polyethylene glycol and zinc oxide. A preparation process comprises the following steps: adding the PET, the PVC, the LDPE, the polyvinyl alcohol, the talcum powder, the polyester fiberand the glass powder into a high-speed stirring machine; stirring and mixing to obtain a mixture I; then adding the polybutylene succinate, the calcium benzoate, the polyethylene wax, the polyethylene glycol and the zinc oxide into the mixture I; after stirring and mixing, raising the temperature under a vacuum condition and keeping for certain time; then adding the antioxidant and the ultraviolet absorbent; after stirring and mixing, extruding and carrying out blow molding through a double-screw extruder to obtain the greenhouse film for gardening. The greenhouse film for gardening, providedby the invention, has good mechanical properties and air permeability.

Description

technical field [0001] The invention belongs to the field of preparation of agricultural operation materials, and in particular relates to a greenhouse film for gardening and a preparation method thereof. Background technique [0002] Greenhouse film is a special plastic film used for facility agriculture or horticultural production and construction. It is another important production-increasing technology after seeds, fertilizers and pesticides. It is of great significance to the efficiency and production increase of agriculture. The current vegetable greenhouse film is usually a single-layer design. Due to sunlight or the respiration of the plant itself, a large amount of water vapor will be generated. Because of the good airtightness of this vegetable greenhouse, water vapor cannot leak out, which will cause the inside of the greenhouse to be stuffy. , It will also condense after cooling down, which seriously affects the temperature and humidity environment inside the gr...
