Cooling and setting device and method for producing stone paper wallpaper base material

Abstract

The invention discloses a cooling and setting device for producing stone paper wallpaper base material. The cooling and setting device consists of a vacuum setting device and two cooling devices, wherein the two cooling devices are two closed annular water or oil jackets; the vacuum setting device is an annular closed chamber; the two closed annular water or oil jackets are respectively connected with two ends of the annular closed chamber to form an overall structure; the annular water or oil jackets are provided with multiple water / oil inlets or water / oil outlets which are uniformly distributed; a joint connected with a vacuum machine is formed in the annular closed chamber; and small holes or linear grooves which are regularly distributed are formed in an inner side wall of the annular closed chamber and are communicated with the annular closed chamber. According to the device, high-temperature parisons extruded from a film blowing machine head have fixed geometrical shapes and sizes, and the stone paper wallpaper base material which accords with related size and quality standard is obtained. The defect that the base material is large in width fluctuation during air cooling of a traditional blowing process is overcome, the absolute accuracy of the size of the stone paper wallpaper base material is guaranteed, the smoothness is greatly improved, and the quality and yield of the product are improved.

Description

technical field [0001] The invention relates to the production technology of building decoration materials, in particular to a cooling and shaping device and method for producing stone paper wallpaper substrates. Background technique [0002] Wall wallpapers were produced in the middle of the 18th century. Initial wallpapers were drawn and printed with various patterns on paper. It has a certain decorative effect, but it is only used for partial decoration in high-end places such as royal courts. The real large-scale entry into home life with other decorative materials began in the late 1970s and 1980s. The development of wallpaper is divided into three stages. The entire 1980s was a period when foam wallpaper was popular. "Foaming" is also called screen relief foaming. By the end of the 1980s, with the development of the plastic industry, there was a substitute for foam wallpaper-glue wallpaper. From the late 1990s to the early 21st century, cloth-like wallpapers became ...

AI Technical Summary

Problems solved by technology

Disadvantages are: poor film thickness uniformity, large width deviation, easy to wrinkle

The patents of the cooling device of the film blowing method are all optimized or adjusted on the original wind ring structure, which is of positive significance for normal film production, but for the production of relatively thick stone paper wallpaper substrates, These methods do not fundamentally solve the problem
