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 molding method for a surface-activated nano-carbon black reinforced HDPE water-supply pipe. The molded pipe is prepared by weighing prepared black master batch and HDPE resin in proportion, carrying out extrusion with a single-screw extruder to prepare a blank pipe and then preparing the molded pipe from the blank pipe by using a sizing sleeve, a cooling water tank, a tractor, a cutting machine and a plate turnover rack. According to the invention, the HDPE water supply and drainage pipe prepared from high-gloss black master batch with a high specific surface area, strong coloring ability, good light stability and obvious enhancement effect is obviously improved in strength, anti-oxidation degree, hydrostatic strength and the like.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for forming a surface activation-treated nano-carbon black reinforced HDPE water supply pipe. Background technique [0002] Black masterbatch is mainly used in chemical fiber products (carpet, polyester, non-woven fabrics, etc.), blown film products (packaging bags, cast films, multilayer composite films, etc.), blow molding products (pharmaceutical and cosmetic containers, paint containers, etc.) , Extrusion products (sheets, pipes, cables, wires, etc.), injection products (auto parts, electrical appliances, building materials, daily necessities, toys, sporting goods, etc.). It has the advantages of convenient use, no pollution to the molding environment, uniform and stable coloring, improving the quality of plastic parts, easy to measure, and can be applied to a molding production system with a high degree of automation, which can integrate coloring, anti-ag...
