Polyvinyl chloride (PVC) embossed film for using on gypsum board and manufacturing method of PVC embossed film

Abstract

The invention discloses a polyvinyl chloride (PVC) embossed film for using on a gypsum board and a manufacturing method of the PVC embossed film. The PVC embossed film comprises polyvinyl chloride (PVC powder), epoxidized soyabean oil (ESO), diisooctyl phenyl phosphate (PDOP), dioctyl phthalate (a plasticizer), calcium zinc stabilizer, barium stearate (a stabilizer), nano CaCO3, chromatic color masterbatch (a coloring Material), hydrous aluminum oxide, stearic acid, weather-resistant impact-resistant modifier (a toughener), a plasticizing promoter, an ultraviolet light absorber and an antioxidant. The invention also provides the manufacturing method of the PVC embossed film. The manufacturing method of the PVC embossed film comprises the following steps: taking materials according to the formula; milling; flattening; cooling and trimming edges; coiling; heating; embossing; cooling and trimming edges; coiling; and packaging to obtain a finished product. The PVC embossed film disclosed by the invention has the advantages of temperature resistance, small chromatic aberration, grain elimination resistance, and small shrinkage, and can be easily stretched, and can be easily attached to the gypsum board without wrinkle and without bubble on a pasting surface.

Description

technical field [0001] The invention relates to a plastic film and a manufacturing method thereof, in particular to a polyvinyl chloride embossed film used on a gypsum board and a manufacturing method thereof. Background technique [0002] At present, the film used for gypsum board veneer has the problems of large color difference on the film surface, difficulty in laminating with gypsum board veneer, wrinkles, uneven embossing at high temperature, no pressure resistance during transportation, and easy to disappear. , resulting in high scrap rate, low production efficiency, and product quality that cannot fully meet domestic and international standards, which restricts the application and development of this technology. Contents of the invention [0003] An object of the present invention is to provide a polyvinyl chloride embossed film for gypsum board, the polyvinyl chloride embossed film provided by the present invention has the characteristics of temperature resistance...
