Wood grain-like PVC pipe and preparation method thereof

Abstract

The invention belongs to a new material and a processing method, and particularly relates to a wood-grain-like PVC pipe and a preparation method thereof. The wood-grain-like PVC pipe comprises color masterbatch A, color masterbatch B and a base material, wherein the color masterbatch A comprises chlorinated polyvinyl chloride, a calcium-zinc stabilizer, a lubricant, a processing aid, an ultraviolet light absorber, an antioxidant and toner; the color masterbatch B comprises PVC resin, EVA wax, a calcium-zinc stabilizer, a plasticizer, a processing aid, a lubricant, a dispersant, an ultraviolet light absorber, an antioxidant and toner; the base material comprises PVC resin, a calcium-zinc stabilizer, CPE, calcium carbonate, a processing aid and a lubricant. The wood grain-like PVC pipe prepared by the invention not only has a wood grain shape, but also is good in heat resistance and high in tensile strength.

Description

technical field [0001] The invention belongs to a new material and a processing method, in particular to a wood-grain imitation PVC pipe and a preparation method thereof. Background technique [0002] In recent years, PVC pipes have been widely popularized and applied in the construction industry, but PVC pipes are mainly white, and wood-grain-like pipes have not been widely involved. With the improvement of people's aesthetics, people are increasingly pursuing the integration of building materials into nature, so that they can be integrated with nature. PVC pipes not only play the role of drainage and sewage, but also have the purpose of beautifying the environment. [0003] Imitation wood grain is a more beautiful style. At present, the imitation wood grain style in PVC pipes is mainly to paste imitation wood grain stickers to beautify the pipes. Rarely use raw materials to directly manufacture imitation wood grain PVC pipes. Moreover, the melting point of most masterbatc...

Problems solved by technology

[0003] Imitation wood grain is a more beautiful style. At present, the imitation wood grain style in PVC pipes is mainly to paste imitation wood grain stickers to beautify the pipes. Rarely use raw materials to directly manufacture imitation wood grain PVC pipes.

Moreover, the melting point of most masterbatches that can form wood grain shapes is much higher than that of PVC resin, so the compatibility between the masterbatch and PVC resin is poor. Adding it to PVC resin will lead to a decrease in the mechanical properties of PVC pipes, and even occur cracking phenomenon
