| titleOfInvention | Polyvinyl chloride rolled film and preparation method thereof |
| abstract | The invention relates to a polyvinyl chloride calendered film and a preparation method thereof, wherein the preparation method comprises the following steps: 1) melting and mixing the raw materials: the raw materials comprise, by weight: 100 parts of universal polyvinyl chloride resin; 1-30 parts of chlorinated polyvinyl chloride resin; 2) preplasticizing the product obtained in the step 1) to obtain a preplasticized product; 3) conveying the preplasticized product to a calender for calendering; the calendering step comprises: i) conveying the preplasticized product to a calendering mechanism, and enabling the preplasticized product to pass through a calendering roller, wherein the temperature of the calendering roller is 180-210 ℃, so as to obtain a calendered product; and ii) stripping the rolled product from the rolling roller by using a leading-out mechanism, and enabling the rolled product to sequentially pass through a first leading-out roller set and a second leading-out roller set, wherein the temperature of the first leading-out roller set is 20-50 ℃, and the temperature of the second leading-out roller set is 80-120 ℃. The polyvinyl chloride calendered film obtained by the method has better transparency and lower glossiness. |
