Abstract

The invention belongs to the technical field of agricultural film preparation, and particularly relates to a high-dust-proof high-heat-preservation pesticide-resistant PO film functional master batch, a five-layer co-extrusion PO film and a preparation method thereof. The high-dust-proof high-heat-preservation pesticide-resistant PO film functional master batch is composed of an outer-layer dust-proof long-life master batch, a secondary outer-layer infrared barrier master batch, a middle-layer heat-preservation master batch, a secondary inner-layer infrared barrier master batch and an inner-layer polar master batch. The secondary outer-layer infrared barrier master batch and the secondary inner-layer infrared barrier master batch both contain transparent heat preservation agents, and the middle-layer heat preservation master batch contains EVA resin. The invention also provides a five-layer co-extrusion PO film prepared from the PO film functional master batch and a preparation method thereof. The five-layer co-extrusion PO film is a multifunctional film integrating aging resistance, dust prevention, high heat preservation, high light transmittance, friction resistance and pesticide resistance. The invention provides the preparation method of the five-layer co-extrusion PO film functional master batch with high dust prevention, high heat preservation and pesticide resistance, and the preparation method is scientific, reasonable, simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of agricultural film preparation, and in particular relates to a PO film functional masterbatch with high dustproof, high heat preservation and pesticide resistance, and a five-layer co-extruded PO film and a preparation method thereof. Background technique [0002] At present, the functional masterbatch products for agricultural film mainly use linear low-density polyethylene (LLDPE) and low-density polyethylene (LDPE) to add conventional light stabilizers and antioxidants. After being stirred by a high-speed mixer, they are extruded through a twin-screw extruder. Manufactured by dicing. Due to the formula, raw material properties and equipment reasons during the processing and use of the product, the masterbatch cannot be added or no relevant quality aids are added during the production and processing process, which makes the PO film product lack some functions or some functions are lacking. , unable to m...
