Abstract

The invention discloses a polyethylene of raised temperature (PERT)-II-type pearly-lustre gold marine water supply and drainage pipeline chromosome. The PERT-II-type pearly-lustre gold marine water supply and drainage pipeline chromosome is prepared from the following raw material components in parts by weight: 70-85 parts of a carrier, 10-20 parts of pearly-lustre gold powder, 10-22 parts of a processing agent, and 6-10 parts of a surfactant, wherein the carrier is PERT formed by high density polyethylene which is copolymerized. Compared with the prior art, the PERT-II-type pearly-lustre goldmarine water supply and drainage pipeline chromosome has the characteristics of rusting prevention, bacterium resistance, hydrolysis resistance, good insulativity, beautiful decoration, fastness andthe like and the advantages of low cost, convenient processing and construction processes and the like; and through introduction of the processing agent, the effect of coordinative coating is achieved, thus under the situation that a pipe processed through the chromosome absorbs light rays with different wave lengths, ordered arrangement of pearly-lustre gold is not destroyed, and the performancecharacteristics of high temperature resistance, illumination resistance, acid and alkali resistance, discoloring avoidance and the like of the pearly-lustre gold are sufficiently presented.

Description

technical field [0001] The invention relates to the technical field of raw material processing of plastic pipes, in particular to a PERT-II pearlescent gold marine water supply and drainage pipe chromosome and a preparation method thereof. Background technique [0002] In recent decades, with the continuous development of PERT-Ⅱ pipe, its performance has been continuously optimized, and it is widely used in municipal engineering, gas transmission, water supply and drainage projects such as buildings and ships. For ship water supply and drainage projects, PERT-Ⅱ pipes can be used in the cold and hot water transmission piping system in the superstructure of the ship's living area, drinking water transmission piping system, domestic sewage discharge piping system, ballast tank ballast water piping system, For systems such as bilge water piping and ventilation piping, ships that have been traveling on the ocean for a long time, because the seawater is alkaline and contains many ...
