Anti-aging polyethylene color masterbatch and preparation method thereof

Abstract

The invention discloses anti-aging polyethylene color masterbatch. The anti-aging polyethylene color masterbatch is prepared from, by weight, 60-90 parts of polyethylene, 20-30 parts of inorganic pigments, 2-3 parts of a composite dispersion agent, 2-3 parts of an ultraviolet absorber, 20-30 parts of bamboo charcoal fibers, 1-2 parts of a phenol antioxidant 1010 and 1-2 parts of filler. The polyethylene color masterbatch is low in cost, safe and environmentally friendly and contains bamboo charcoal fibers, the antibacterial rate reaches 90% or above, and low ultraviolet transmittance is realized; by adoption of phenyl salicylate and 2-hydroxyl-4-methoxybenzophenone as the ultraviolet absorber, high resin compatibility and wide absorption wavelength range are realized, and effects of a stabilizing agent and a plasticizer are achieved. In application to coloring of polyethylene products, the anti-aging polyethylene color masterbatch has advantages of high aging resistance, uniformity incoloring, freeness of discoloration, high antibacterial rate, low consumption, freeness of influences on mechanical performances of the products and the like, and the service life of the polyethylenematerial is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anti-aging polyethylene color masterbatch and a preparation method thereof. Background technique [0002] Polyethylene (referred to as PE) is a thermoplastic resin obtained by polymerization of ethylene. It also includes copolymers of ethylene and a small amount of α-olefins in industry. Polyethylene is odorless, non-toxic, has excellent low temperature resistance, good chemical stability, and can withstand most acids and alkalis. It has a wide range of uses, mainly used to manufacture films, packaging materials, pipes, various hollow products, wires and cables, daily necessities, etc. Under the action of atmosphere, sunlight and oxygen, polyethylene will age, discolor, crack, become brittle or pulverized, and lose its mechanical properties. [0003] At present, masterbatch coloring is the most commonly used plastic coloring method. Domestic color mast...

Problems solved by technology

The method of adding a single masterbatch makes it necessary to add a variety of color masterbatches with different functions when the comprehensive performance of the carrier resin is high, thus consuming a large amount of carrier resin and resulting in the consumption of antioxidants during processing Due to the disadvantages of high volume, many components in downstream molding processing, and complicated processes, the future masterbatch will continue to develop in the direction of multi-functionality, high color content and high technology content.
