Abstract

The invention discloses hydrophobic polyethylene masterbatch and application thereof in a plastic greenhouse film. The hydrophobic polyethylene masterbatch comprises the following raw materials in parts by weight: 3-5 parts of polyethylene, 70-80 parts of talc, 25-30 parts of calcium stearate, 5-8 parts of a hydrophobic agent and 0.9-1.5 parts of an auxiliary agent. At the same time, the inventionalso discloses the application of the hydrophobic polyethylene masterbatch in the plastic greenhouse film. The invention aims at improving the technical problems that small water droplets easily condense on the inner walls of existing polyethylene plastic greenhouse films in early spring or late autumn season when the humidity is high, and the existing plastic greenhouse films are poor in hydrophobicity, so as to affect the light transmittance. The hydrophobic polyethylene masterbatch and a polyethylene film provided by the invention have relatively good effects on use intensity and hydrophobicity, and the promotion and use by farmers are facilitated.

Description

technical field [0001] The invention relates to a polyethylene masterbatch, in particular to a hydrophobic polyethylene masterbatch and its application on plastic greenhouse films. Background technique [0002] Polyethylene is a polymer formed by the polymerization of ethylene monomer. Polyethylene is the polymer with the simplest structure and the most widely used polymer material. Masterbatches (English name Masterbatches), the full name of plastic masterbatches, is a plastic processing aid developed and stood up in the 1980s. It is composed of excessive chemical additives, carrier resins and dispersants. In the plastic processing and molding process, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are mixed and kneaded first, and then measured, mixed, melted, extruded, and pelletized by extruders and other equipment Pellets made during processing. Masterbatch is generally composed of carrier resin, various fi...
