Nano flame-retardant plastic film and preparation method thereof

Abstract

The invention discloses a nano flame-retardant plastic film and a preparation method thereof. The nano flame-retardant plastic film comprises the following raw materials: high-density polyethylene, amodified flame retardant, a plasticizer, magnesium oxide crystals, nano silicon dioxide, an antibacterial agent, an ultraviolet absorbent, a light stabilizer, a dispersing agent and an antioxidant. High-density polyethylene is used as a base material for preparing the nano flame-retardant plastic film; in the preparation process, the surface activity is improved by grinding the magnesium oxide whiskers and the nano silicon dioxide, quick dispersion in high-density polyethylene can be realized, the tensile strength of the nano flame-retardant plastic film is enhanced; meanwhile, the plasticizers are environment-friendly and non-toxic; main and auxiliary plasticizers are matched for use; according to the flame-retardant plastic film, the polyvinyl chloride and the chlorinated polyethylene resin can be fully wetted through the synergistic effect of the polyvinyl chloride and the chlorinated polyethylene resin, and can be well prevented from being decomposed in the processing process so that the raw materials have excellent cross-linking property and plasticizing effect, and the durability and the thermal stability of the nano flame-retardant plastic film can be effectively improved byadding the ultraviolet absorbent, the light stabilizer and the antioxidant.

Description

technical field [0001] The invention belongs to the technical field of plastic film preparation, in particular to a nano flame-retardant plastic film and a preparation method thereof. Background technique [0002] Packaging materials refer to the materials used to make packaging containers, packaging decoration, packaging printing, packaging and transportation to meet product packaging requirements, including metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, Main packaging materials such as chemical fibers and composite materials, as well as auxiliary materials such as strapping, decoration, and printing materials. There are many kinds of commodity packaging materials in social production and life. Packaging is constantly changing and improving with the development of human civilization. The chemical industry is working hard towards environmentally friendly materials. With the growth of the population, the demand for packaging is also increasin...

AI Technical Summary

Problems solved by technology

[0004] 1. The existing flame-retardant plastic film has poor flexibility, difficult stretching and poor retractability, low transparency and low tensile strength, and is easy to be damaged;

[0005] 2. The existing flame-retardant plastic film has a technical problem of poor flame-retardant effect during use;

[0006] 3. During the winding process of the existing flame-retardant plastic film through the winding frame, due to the presence of more static electricity in the production process of the flame-retardant plastic film, the surface of the flame-retardant plastic film is easy to absorb dust, and at the same time because the flame-retardant plastic film Static electricity is carried on the surface of the flame retardant plastic film, which makes the rewinding of the flame retardant plastic film not strong, and increases the difficulty of rewinding the flame retardant plastic film
