Problems solved by technology

Therefore, the usual way to obtain a bright black glossy surface is to spray high-gloss paint on the surface of the workpiece for post-treatment, and spraying high-gloss paint will not only increase the cost by 30%, increase the process, but also cause about 10% of unqualified products, and these substandard products cannot be recycled; the second is to use the compounding of several organic dyes to achieve a high gloss effect, but this method is not only due to high cost, but also has the same scratch resistance as carbon black Cannot meet the requirements, so it is rarely used in the application of black goods
[0005] However, in the existing technology, the preparation of black masterbatch has the disadvantages of low concentration, pollution of toner dyeing, poor dispersion of carbon black in resin, and low blackness and brightness.

Abstract

The invention discloses a preparation method of a highlight black master batch applied to an HDPE (High-density Polyethylene) water supply and drainage tubular product. The preparation method comprises the following steps: internally mixing by utilizing an internal mixer to obtain a uniform melt; extruding and granulating the molded uniform melt through a single-screw extruder to obtain the black master batch. According to the highlight black master batch disclosed by the invention, raw materials are reasonably selected and the raw materials are reasonably proportioned so that nano carbon black in the prepared highlight black master batch has a large specific surface area, strong coloring capability, good light stability and an obvious enhancing effect; the strength, anti-oxidization degree and hydrostatic strength of the HDPE water supply and drainage tubular product prepared from the highlight black master batch are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a high-gloss black masterbatch applied to HDPE water supply and drainage pipes. Background technique [0002] Black masterbatch is mainly used in chemical fiber products (carpets, polyester, non-woven fabrics, etc.), blown film products (packaging bags, cast films, multi-layer composite films, etc.), blown products (medicine and cosmetic containers, paint containers, etc.) , Extruded products (sheets, pipes, cables, wires, etc.), injection products (auto parts, electrical appliances, building materials, daily necessities, toys, sporting goods, etc.). It is easy to use, has no pollution to the molding environment, has uniform and stable coloring, improves the quality of plastic parts, is easy to measure, and can be applied to a molding production system with a high degree of automation. It can integrate coloring, anti-aging agents, and antistatic ...
