Problems solved by technology

[0002] Polyvinyl chloride resin is a strong polar polymer with strong intermolecular force, which leads to high softening temperature and melting temperature of polyvinyl chloride resin. Generally, it needs to be higher than 120°C to produce and process. In the production of certain special pressure When embossing, the non-embossed surface is required to be high gloss and mirror surface, but the conventional embossing mechanism is an embossing roller and rubber roller set, and the conventional rubber roller will cause the non-embossed surface to be a low-gloss matte surface
Although high-gloss rubber rollers are now used to meet the requirements of high-gloss and mirror surfaces for non-embossed surfaces, high-gloss mirror rubber rollers are extremely expensive and have a short service life; in addition, when the embossed PVC film , the PVC film will transfer the pattern to the high gloss and mirror non-embossed surface due to rolling or folding, reducing its gloss and leaving lines, which seriously affects the special embossing effect

Embodiment 1

[0100] A polyvinyl chloride film (referred to as PVC film) with a glossiness of 75 is obtained by calendering molding process, and the PVC film is placed on the first feeding roller group; the polyethylene terephthalate film (referred to as PET film) is placed on the on the second supply roll set. Under the traction of the first feeding wheel set, the PVC film is preheated through the first preheating wheel set at a traction rate of 12m / min, and the preheating temperature is 80°C; under the traction of the second feeding wheel set , the PET film is preheated through the second preheating wheel set at a traction speed of 12m / min. The preheating temperature is 80°C. Laminate the preheated PVC film and PET film through the laminating wheel set at a traction rate of 3 m / min to obtain a laminating film. The laminated film is embossed through an embossing wheel set, then cooled through a cooling wheel set, and finally coiled to obtain a finished product. The thicknesses of the fin...

Embodiment 2

[0102]A polyvinyl chloride film (referred to as PVC film) with a glossiness of 100 was obtained by calendering molding process, and the PVC film was placed on the first feeding roller group; the polyethylene terephthalate film (referred to as PET film) was placed on the on the second supply roll set. Under the traction of the first feeding wheel set, the PVC film is preheated through the first preheating wheel set at a traction rate of 18m / min, and the preheating temperature is 120°C; under the traction of the second feeding wheel set , the PET film is preheated through the second preheating wheel set at a traction speed of 18m / min. The preheating temperature is 120°C. Laminate the preheated PVC film and PET film through the laminating wheel set at a traction rate of 15 m / min to obtain a laminating film. The laminated film is embossed through an embossing wheel set, then cooled through a cooling wheel set, and finally coiled to obtain a finished product. The thicknesses of t...

Embodiment 3

[0104] A polyvinyl chloride film (referred to as PVC film) with a glossiness of 125 was obtained through an extrusion molding process, and the PVC film was placed on the first feeding roller group; the polyimide film was placed on the second feeding roller group. Under the traction of the first feeding wheel set, the PVC film is preheated through the first preheating wheel set at a traction rate of 22m / min, and the preheating temperature is 180°C; under the traction of the second feeding wheel set , the polyimide film is preheated through the second preheating wheel set at a pulling speed of 22 m / min. The preheating temperature is 180°C. Laminate the preheated PVC film and the polyimide film through the laminating wheel set at a traction speed of 25 m / min to obtain a laminating film. The laminated film is embossed through an embossing wheel set, then cooled through a cooling wheel set, and finally coiled to obtain a finished product. The thicknesses of the finished PVC film a...

Abstract

The invention discloses an embossing method for a polyvinyl chloride film. The embossing method for a polyvinyl chloride film sequentially comprises the following steps of: placing the polyvinyl chloride film and an embossing protective film in a feeding wheel group respectively; performing preheating treatment on the polyvinyl chloride film and the embossing protective film via a preheating wheel group respectively; bonding the preheated polyvinyl chloride film and embossing protective film via a bonding wheel group, so as to obtain a bonded film; and embossing, cooling and winding the bonded film, so as to obtain the finished product. With the adoption of the embossing method disclosed by the invention, a layer of high-temperature-resistant protective film is added outside the polyvinyl chloride film, so as to obtain an embossed film product with a high-glossiness and high-mirror-finish non-embossed surface.
