Embodiment 1

[0036] Embodiment 1: take by weighing PVC resin powder 100kg; Strengthening agent methyl methacrylate-butadiene-styrene copolymer 10kg; Stabilizer organotin heat stabilizer 1.0kg; Processing aid methacrylate and acrylate Parapolymer 1.0kg; Lubricant pentaerythritol stearate 0.5kg.

[0037] The above mixture is mixed evenly by a mixer, and then sent to a planetary screw extruder for melt extrusion. The extruded material is calendered by a calender, and the calendering temperature is controlled at 200-220°C. After calendering, it enters the embossing station and uses a roller Embossing, the embossing temperature is 140°C, after embossing, it is conveyed to the shaping station by the conveying roller to the shaping station for constant temperature shaping, the shaping temperature is 90°C, the conveying speed of the conveying roller is 20m / min, the shaping time is 60s, and after shaping, it passes through the conveying roller Transport to the cooling station for cooling, the cooli...

Abstract

The invention belongs to the technical field of luggage materials and relates to a luggage plastic sheet and a preparation method thereof. The upper surface of the luggage plastic sheet is a brushed face while the lower surface of the same is a smooth face, and the luggage plastic sheet is made of PVC. The preparation method includes following steps: well mixing various raw materials for preparingPVC, feeding into an extruder, heating for extrusion, calendering an extruded material, using a compression roller to emboss after calendering, shaping at constant temperature after embossing, cooling after shaping, and winding after cooling to obtain the luggage plastic sheet, wherein the surface of the compression roller is engraved with brushed texture. By using the PVC brushed sheet for making luggage, the luggage has metal brushed texture and is light, thin, flexible, high in impact resistance and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of luggage materials, and relates to a plastic sheet for luggage and a preparation method thereof. Background technique [0002] Luggage brushed plastic sheet is a material for drawing the plastic surface, which is mainly used for the outer film of luggage. The surface of the bag looks metallic, and at the same time has the light and thin characteristics of the plastic material and good flexibility. In addition, the brushed treatment can also prevent slight scratches, the surface is dirt-resistant, and it is not easy to leave fingerprints. [0003] The plastic surface is not as easy to be drawn as the metal surface, and the process of drawing the plastic surface is relatively difficult. At present, the known drawing plastic sheet for luggage is mainly made of PC material, and the drawing process is mainly quenched and shaped after embossing. The main problems in the above-mentioned process are that the prod...
