Embodiment Construction

[0014] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0015] A micro-shrink ultra-permeable film, according to the weight ratio, its raw materials are composed of: 100 parts of PVC rubber, 12 parts of titanium dioxide, 26.5 parts of plasticizer, 1.5 parts of titanate, 4 parts of calcium titanate, and 9.75 parts of processing aids share.

[0016] The plasticizer includes 6 parts of paraffin, 5 parts of phytosterol, 1.5 parts of graphene, 6 parts of zinc borate, 3 parts of water glass and 5 parts of coal essence. Graft copolymerization of graphene and resin makes the glass transition temperature higher than that of the resin itself. Decomposition temperature, and the decomposition temperature of grafting is 40-400°C higher than that of resin, so that it can maintain goo...

Abstract

The present invention discloses a micro-shrinking ultra-transparent thin film. The micro-shrinking ultra-transparent thin film comprises the following raw materials in parts by weight: 100 parts of PVC glue, 10-15 parts of titanium dioxide, 10-30 parts of a plasticizer, 1-2 parts of titanate, 3-5 parts of calcium titanate and 6-18 parts of a processing aid. The processing aid comprises 0.2-0.4 part of lignin fiber and 0.3-0.6 part of lanthanum oxide. The lignin fiber and lanthanum oxide are added, so that molecules are more closely linked. The ultra-transparent thin film is micro-shrunk duringcutting and use.

Description

technical field [0001] The invention belongs to the technical field of PVC, and in particular relates to a micro-shrink ultra-permeable film. Background technique [0002] Polyvinyl chloride is referred to as PVC in English. With the excellent properties of low toxicity, flame retardancy, cold resistance and environmental protection, PVC film has become more and more widely used. It is widely used in documents, booklets, packaging, luggage, clothing, footwear, automobiles, etc. Decoration and other fields have developed into the field of daily life and PVC products can be seen everywhere. It can be seen from these that the demand for PVC film is increasing. [0003] However, PVC films, especially ultra-permeable films, tend to shrink and wrinkle during cutting and use, which affects the appearance, and when cutting, due to shrinkage, the size is shortened. Contents of the invention [0004] The invention overcomes the disadvantages of the prior art and provides a micro-s...
