Embodiment 1～10

[0018] The embodiment of the high-temperature pattern-stabilized PVC film of the present invention, the formula of the high-temperature pattern-stabilized PVC film described in this embodiment is shown in Table 1, and the preparation method is: put the materials into a mixer and mix them evenly, and then add banburying Mixing in a machine or a planetary machine, then mixing in a double-roller mill, filtering in a filter, and then calendering through a calender wheel, leading out from the pull-out wheel to embossing wheel embossing, cooling, slitting and winding, The high-temperature pattern-stable PVC film was obtained. Wherein, the mixing temperature is 100° C., the temperature of the filter is 150° C., the rotating speed of the calendering wheel is 30 m / min, and the temperature of the cooling wheel is 30° C.

Abstract

The invention discloses a high-temperature pattern-stabilized PVC film, a preparation method and application thereof, and relates to the technical field of polymer materials. The high-temperature pattern-stabilized PVC film of the present invention comprises the following ingredients in parts by weight: 100 parts of PVC resin powder, 5-35 parts of main plasticizer, 1-10 parts of epoxy auxiliary plasticizer, and 1-9 parts of stabilizer , 0.1-5 parts of processing aids, 5-20 parts of fillers and 5-15 parts of pigments. The high-temperature pattern-stable PVC film prepared with the formula of the present invention has good high-temperature stability, and the pattern and luminosity are still stable and almost unchanged under high-temperature environments; and, the present invention selects the proportion of each component, The prepared PVC film has good impact strength.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PVC film with high-temperature pattern stability and a preparation method and application thereof. Background technique [0002] Because PVC is plastic when heated, easy to print and emboss patterns, and has certain flame retardancy, high quality and low price, it is more and more widely used in building materials and decoration industries, especially in the surface decoration fields of metal ceilings, metal doors and windows, etc. The demand continues to expand, not only to make the three-dimensional color of the metal shape rich and textured, pleasing to the eye, but also to protect the metal material from the invasion of water vapor, oxygen and other impurities, and to increase the service life. However, the embossed film currently available on the market almost disappears during the high-temperature lamination process with the metal plate, the film becomes brighte...
