Problems solved by technology

Through the combination of wear-resistant layer, polyethylene layer, polyurethane layer, base layer, temperature-resistant layer, polyethylene terephthalate layer, polycarbonate layer, and polytetrafluoroethylene layer, however, The surface stability of this high temperature resistant polypropylene film is poor, and the surface cannot be drawn
[0006] Therefore, the present invention provides a high-temperature-resistant polypropylene wire-drawn film and its preparation method for the problems of insufficient temperature resistance, insufficient glossiness of the polypropylene film after wire-drawing, low production efficiency, and high production cost that are common in the current polypropylene wire-drawn film

Abstract

The invention discloses a high-temperature-resistant polypropylene wire drawing film and a preparation method thereof. The high-temperature-resistant polypropylene wire-drawn film is sequentially composed of a main temperature-resistant layer A, a secondary temperature-resistant layer B, a toughening layer C and a main temperature-resistant layer D composition; the mass ratio of the main temperature-resistant layer A, the secondary temperature-resistant layer B, the toughening layer C and the main temperature-resistant layer D is 18-22:30:30:20; the main temperature-resistant layer A and the main temperature-resistant layer The raw material of the temperature-resistant layer D is homopolypropylene with high crystallinity; the raw material of the secondary temperature-resistant layer B is homopolypropylene; the raw material of the toughened layer C is ethylene-propylene rubber. The high-temperature-resistant polypropylene wire drawing film prepared by the present invention has a four-layer structure, and the high-temperature resistance performance of the product is realized through multi-layer temperature-resistant settings, which can effectively solve the problems of poor temperature resistance and material deformation of the polypropylene film in the wire-drawing production process. At the same time, the high-temperature-resistant polypropylene wire-drawn film has a more lustrous wire-drawn appearance and is more widely used.

Description

technical field [0001] The invention relates to the technical field of plastic films, in particular to a high temperature resistant polypropylene wire drawing film and a preparation method thereof. Background technique [0002] With the economic progress, the flexible packaging industry is booming, and all kinds of flexible packaging are more refined and refined. After all, the exquisite packaging appearance can be more popular with consumers and stimulate consumers' desire to buy, which has prompted more downstream enterprises to refine , Exquisite film appearance, and polypropylene brushed film is the product born under this trend. [0003] The polypropylene drawing film is a product obtained by embossing the surface of the polypropylene film at a high temperature by a drawing machine. The polypropylene drawing film has a very beautiful appearance and is widely used in various product packaging. However, the polypropylene film needs to be contacted with a high-temperature...
