High strength scratch-resistant anti-cutting flexible protective film

Abstract

The invention mainly relates to the technical field of processing of willow knitted protective films, and discloses a high strength scratch-resistant anti-cutting flexible protective film. The protective film is prepared from the following raw materials: 67 to 69 of modified polyvinyl chloride, 25 to 27 of linear low density polyethylene, 22 to 24 of polyester fiber, 11 to 13 of sepiolite fiber, 8to 10 of graphene fiber; the high strength scratch-resistant anti-cutting flexible protective film provided by the invention is safe and healthy, does not contain toxic components, the color and luster of the protective film is light black, not only can observe the shape and color of willow knitted products through the protective film, but also can avoid direct sunlight exposure to the willow knitted products, has high strength and flexibility, can be prevented from scratching or cutting during use, and can protect the willow knitted products from being damaged during storage and transportation.

Description

technical field [0001] The invention mainly relates to the technical field of wicker protective film processing, in particular to a high-strength scratch-resistant and cut-resistant flexible 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 type...

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 protective films, there is no protective film for wickerwork

[0003] Willow products are handicrafts or daily necessities woven with plant branches, stems, leaves, skins, etc. by hand or semi-manually. Because of the particularity of the materials, the willow products are prone to appear when the air humidity is too small. Cracking, too much air humidity, willow products will absorb water and become damp easily, moldy and insect-eaten, which will cause damage to willow products. At present, most of the traditional methods of preventing cracking and moldy and insect-eaten willow products focus on the plant material itself However, the repeated treatment of plant materials before or after weaving will easily reduce the flexibility of the weaving materials, which will have a negative impact on the quality of willow products, and a variety of chemical components will be used in the processing of plant materials, which may cause It is also toxic, which will damage the health and pollute the environment during the processing process. At present, the woven willow products will be wrapped with plastic film during storage to reduce the impact of the external environment on the willow products. However, the traditional plastic film currently used The strength is low, because the surface of the willow is uneven, so it is easy to be worn, scratched or cut during the storage and transportation of the willow, so that the willow is exposed to the environment and cannot provide ideal protection effect

[0004] The existing patent document CN 106553417 A discloses a high-strength puncture-resistant self-adhesive protective film, which is prepared in layers. The raw materials are mLLDPE, LLDPE, EVA and random impact copolymer polypropylene, which has high strength, durability Puncture effect and good optical transparency, but the hardness of the protective film is too high, it is not easy to fold, and the surface of the willow product is not smooth, it is difficult to self-adhesive, and the transparency of the protective film is too high, the willow product will be exposed to direct sunlight, easy to produce fading or cracking; patent document CN 107779114 A discloses a high-strength protective film, the base film includes a front and a back, the front of the base film is provided with a pressure-sensitive adhesive layer, the back of the base film is provided with a release agent layer, and the base film The material is nanofiber-doped polyethylene, which has high transparency and cannot block the sun's rays on the willow products. At the same time, due to the unevenness of the surface of the willow products, the force on the front pressure-sensitive adhesive layer is uneven, and the protective film is easy to fail. paste
