Embodiment 1

[0024] Depend on figure 1 As shown, a weather-resistant film for plastic flooring in this embodiment is formed by co-extrusion of an outer protective layer 1, a functional layer 2 and an adhesive layer 3 with a thickness ratio of 1:3:1. The outer protective layer 1 is fluorine-containing The high polymer polyvinylidene fluoride and polytetrafluoroethylene are mixed in a ratio of 100:3, and the functional layer 2 is a mixture of polyvinylidene fluoride, polyacrylic resin and functional additives in a ratio of 60:30:10.5. The functional additive is made by mixing UV absorber and toughening agent at a ratio of 0.5:10, and the adhesive layer 3 is made of fluorine-containing high polymer polyvinylidene fluoride and modified polyacrylic resin at a ratio of 60:40. The proportion is mixed; the weather-resistant film for plastic flooring of this embodiment can be connected with the polyvinyl chloride floor layer by hot-melt bonding through the adhesive layer 3.

Embodiment 2

[0026] Depend on figure 1 As shown, a weather-resistant film for plastic flooring in this embodiment is formed by co-extrusion of an outer protective layer 1, a functional layer 2 and an adhesive layer 3 with a thickness ratio of 1:3:1. The outer protective layer 1 is fluorine-containing The high polymer polyvinylidene fluoride and polytetrafluoroethylene are mixed in a ratio of 100:10, and the functional layer 2 is a mixture of polyvinylidene fluoride, polyacrylic resin and functional additives in a ratio of 80:20:1. The functional auxiliary agent is formed by mixing antioxidant and toughening agent in a ratio of 0.5:0.5, and the bonding layer 3 is polyethylene-vinyl acetate resin; the weather-resistant film for plastic flooring in this embodiment can be bonded Layer 3 is hot melt bonded to the polypropylene floor layer.

Embodiment 3

[0028] Depend on figure 1 As shown, a weather-resistant film for plastic flooring in this embodiment is formed by co-extrusion of an outer protective layer 1, a functional layer 2 and an adhesive layer 3 with a thickness ratio of 1:3:1. The outer protective layer 1 is fluorine-containing High polymer polyvinylidene fluoride, the functional layer 2 is made of polyvinylidene fluoride and functional additives in a ratio of 90:10, and the functional additives are UV absorbers and tougheners in a ratio of 2:8 The adhesive layer 3 is formed by mixing polyvinylidene fluoride and polyvinyl butyral resin in a ratio of 10:90; the weather-resistant film for plastic flooring in this embodiment can be bonded to the polyethylene floor through the adhesive layer 3 The layers are connected by hot melt bonding.

Abstract

The invention discloses a weather-proof film for a plastic floor. The weather-proof film is formed by an outer protection layer, a function layer and an adhesion layer of which the thickness ratio is 1 to 3 to 1 through co-extrusion, wherein the outer protection layer is prepared from a fluorine-containing high polymer; the function layer is prepared from 20 to 100 parts of fluorine-containing high polymer, 0 to 60 parts of hot melt glue and 0.5 to 20 parts of functional aid; the adhesion layer is prepared from 0 to 40 parts of fluorine-containing high polymer and 60 to 100 parts of hot melt glue. The weather-proof film for the plastic floor, disclosed by the invention, has the characteristics of strong stain resistance, chemical inertness, high wear resistance, environment friendliness, weather resistance and universality.

Description

technical field [0001] The invention relates to a weather-resistant film for a plastic floor. Background technique [0002] The growth momentum of the fluoropolymer membrane market comes from the ever-expanding application fields. In addition, the compatibility of fluoropolymer membranes with other membranes and the development of multilayer coating technology, as well as the growing demand in the pharmaceutical and pharmaceutical industries, also promote the rapid expansion of its market size. The technical blockade and industrial threshold of the fluorine-containing special film processing industry are relatively high. In order to break the technical barriers of relevant countries, promote the development of fluorine-containing resins in China and meet market demand, it is necessary to segment the market and guide it through breakthrough innovative technologies. market development. This application extends the application field of the fluorine-containing film to the plas...
