An anti-ultraviolet, flame-retardant and cut-resistant protective film

Abstract

The invention mainly relates to the technical field of wicker protection film processing and discloses an anti-ultraviolet flame-retardant cutting-resistant protection film. The protection film is prepared from modified PET, linear low density polyethylene, polystyrene, vermiculite fiber, graphene fiber, titanium dioxide and nano zinc oxide. The protection film is high in strength, and damage to the protection film in the process of storage and transportation after a wicker product is packed by the protection film can be avoided; the protection film is light grey in color and luster, so that shape and color and luster of the wicker product can be observed through the protection film; illumination and ultraviolet can be reduced effectively, so that deformation of the wicker product caused by illumination is avoided; the protection film has high flame retardance and can inhibit high-temperature damage of the wicker product, the conventional mode of directly treating a wicker material isavoided, the treatment process of the wicker material is reduced, flexibility and lightness of the material are protected, and decoration performance and using performance of the wicker product are improved.

Description

technical field [0001] The invention mainly relates to the technical field of wicker protective film processing, in particular to an ultraviolet-proof, flame-retardant and cut-resistant protective film. Background technique [0002] Protective films are films that protect products and are mainly made of polyolefins. Traditional protective films are generally used for digital products, automobiles and food, and there are many types of protective films on the market, which can be divided into plastic protective films, digital product protective films, automotive protective films, household protective films, and food fresh-keeping protective films. etc.; according to properties, it can be divided into adhesive film and self-adhesive film; according to the glue system, it can be divided into rubber and acrylic glue; according to the base material, it can be divided into PE base material, PVC base material, PET base material, OPP base material ; Although there are many types of ...

[0003] Willow products are handicrafts or daily necessities woven with plant branches, stems, leaves, skins, etc. by hand or semi-manually. If it is too small, the willow products will be prone to cracking. If the air humidity is too high, the willow products will easily absorb water and become damp, moldy and insect-eaten. Direct sunlight will cause deformation and discoloration of the willow products, which will cause damage to the willow products. The current traditional willow products Most of the methods to prevent burning, cracking, mould, insects, deformation and discoloration are to treat the plant material itself, but the repeated treatment of the plant material before or after weaving will easily lead to the reduction of the flexibility of the weaving material, which will affect the quality of willow products. produce adverse effects, and a variety of chemical components will be used in the processing of plant materials, some of which are toxic and will cause harm to the human body and the environment. At present, the woven willow products will be stored and transported with ordinary Plastic film is wrapped to reduce the impact of the external environment on willow products, but the strength of the traditional plastic film currently used is low, and the uneven surface of the willow is easy to damage the protective film, and ordinary mortal plastic films cannot be flame-retardant and reduce The effect of ultraviolet rays is not ideal for the protection of willow products

[0004] The existing patent document CN 104553215 A discloses a transparent flame-retardant, heat-insulating and anti-ultraviolet polymer composite film, which is prepared in layers. From top to bottom, it is a flame-retardant functional layer, a substrate layer, a heat-insulating The ultraviolet functional layer has good flame retardant and UV reduction functions, but the composite film is completely transparent and cannot reduce the sunlight on the willow products. After long-term sunlight exposure, the willow products will still be cracked and deformed, and the composite film has multiple layer structure, the preparation process is complicated, each functional layer is easy to separate from the substrate, and the strength of the composite film is low. It is generally used on transparent materials such as glass. Willow products can easily puncture the composite film, which shortens the use of the composite film. Longevity; patent document CN 106883781 A discloses an anti-ultraviolet and flame-retardant tape, which also has a multi-layer structure, which is an anti-ultraviolet layer, a first adhesive layer, a flame-retardant layer, a second adhesive layer, and a base layer in order from top to bottom. , the third adhesive layer, and the protective layer, and the materials are titanium dioxide nano-coating, polyester adhesive layer, red phosphorus flame-retardant layer, polyester adhesive layer, PET film, polyester adhesive layer, release Type film, the preparation process is complicated, and it can only reduce ultraviolet rays, but it cannot reduce the heat generated by sunlight, and it will also cause cracking and deformation of willow products, and the tape cannot be reused.
