Abstract
The invention relates to the technical field of films, in particular to an anti-sticking agricultural film and a preparation method thereof, wherein the anti-sticking agricultural film is prepared from the following raw materials in parts by mass: 50-80 parts of base material, 3-8 parts of stable master batch, 5-20 parts of anti-aging master batch and 5-15 parts of anti-sticking master batch. The base material comprises high-pressure polyethylene resin and linear low-density polyethylene resin, so that the flexibility and the chemical resistance stability of the anti-sticking agricultural film are improved; the stable master batch comprises an environment-friendly stabilizer and an environment-friendly plasticizer, so that the stability and the tensile resistance of the anti-sticking agricultural film are improved; the anti-aging master batch comprises an antioxidant, an ultraviolet absorbent and a light stabilizer, and improves the heat resistance and harmful ultraviolet resistance of the anti-adhesion agricultural film, so that the anti-aging property of the anti-adhesion agricultural film is improved; the anti-sticking master batch comprises silicon dioxide, erucamide and a dispersing agent, so that an air isolating layer is formed between the anti-sticking agricultural films, and the anti-sticking effect is achieved.
Description
Technical Field
The invention relates to the technical field of films, in particular to an anti-sticking agricultural film and a preparation method thereof.
Background
Agricultural films play an important role in agricultural production because of having the functions of preserving heat, preserving moisture, increasing crop yield, adjusting harvest time and the like. The agricultural film can be bonded together in the process of transportation and storage or under the condition of high temperature, so that the use is influenced.
The patent with publication number CN104845367A discloses a plastic agricultural film, which is mainly polymerized by aromatic diamine and biphenyl dianhydride; it is finally filmed through the processes of raw material treatment, resin synthesis, steel band casting, imidization treatment, etc.
The plastic agricultural film also has the following defects: the plastic agricultural film is mainly formed by polymerizing aromatic diamine and biphenyl dianhydride, the anti-adhesion performance is weak, and the common plastic agricultural film is mostly wound into a roll-shaped structure, so that layers of the plastic agricultural film are adhered together; in addition, the anti-aging performance of the plastic agricultural film is weak, the plastic agricultural film is mostly arranged outdoors, and the plastic agricultural film is easy to damage due to long-term ultraviolet irradiation and weather erosion.
Therefore, the anti-bonding agricultural film and the preparation method thereof are provided.
Disclosure of Invention
The invention aims to provide an anti-bonding agricultural film and a preparation method thereof, and aims to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: an anti-sticking agricultural film is prepared from the following raw materials in parts by mass:
50-80 parts of base material, 3-8 parts of stable master batch, 5-20 parts of anti-aging master batch and 5-15 parts of anti-sticking master batch;
the base material comprises high-pressure polyethylene resin and linear low-density polyethylene resin, and the mass ratio of the high-pressure polyethylene resin to the linear low-density polyethylene resin is (3-4);
the stabilizing master batch comprises an environment-friendly stabilizer and an environment-friendly plasticizer, wherein the mass ratio of the environment-friendly stabilizer to the environment-friendly plasticizer is (2-3);
the anti-aging master batch comprises an antioxidant, an ultraviolet absorbent and a light stabilizer, wherein the mass ratio of the antioxidant to the ultraviolet absorbent to the light stabilizer is (1.2-1.4);
the anti-sticking master batch comprises silica, erucamide and a dispersing agent, wherein the mass ratio of the silica to the erucamide to the dispersing agent is 1-1.3.
The environment-friendly plasticizer is one or more of dioctyl terephthalate, synthetic vegetable ester and epoxy plasticizer. The environment-friendly plasticizer can reduce the surface hardness of the high polymer and increase the flexibility of the high polymer, so that the tensile strength of the anti-sticking agricultural film is improved.
The antioxidant is one or more of hindered phenols, phosphites and thio compounds.
