Environment-friendly anti-UV flame-retardant polyethylene material and preparation method thereof

Abstract

The invention discloses an environment-friendly anti-UV flame-retardant polyethylene material and a preparation method thereof. The environment-friendly anti-UV flame-retardant polyethylene material is composed of the following raw materials in parts by weight: 90-95 parts of LDPE, 2.5-4.5 parts of decabromodiphenylethane, 0.8-2.0 parts of antimony trioxide, 0.2-0.5 part of an antioxidant, 0.2-0.8part of an anti-UV agent, 0.5-2.0 parts of titanium dioxide and , 0.3-0.7 part of a lubricant; and the preparation method comprises the following steps: 1) adding LDPE, decabromodiphenylethane, antimony trioxide, titanium dioxide and the lubricant into a high-speed mixer for mixing uniformly, then adding the antioxidant and the anti-UV agent for mixing uniformly; and 2) transferring the materialsof the step 1) to a co-rotating twin-screw extruder for mixing and extruding, stripping, pelletizing and screening after cooling. The environment-friendly anti-UV flame-retardant polyethylene material provided by the invention has the advantages of excellent flame retardancy, excellent anti-UV and anti-aging performances, good weather resistance, difficult fading and discoloration, simple preparation method, low production cost and easy industrial large-scale production.

Description

technical field [0001] The invention relates to an environment-friendly anti-UV flame-retardant polyethylene material and a preparation method thereof, belonging to the technical field of flame-retardant composite materials. Background technique [0002] Polyethylene (PE) has the advantages of odorless, non-toxic, excellent low temperature resistance, good chemical stability, resistance to most acids and alkalis, low water absorption, and excellent electrical insulation. It is widely used in chemical industry, agriculture, construction and packaging and other fields. Among them, the demand for polyethylene in the simulated PE decoration industry is increasing, and the requirements are becoming stricter and stricter. Many products have been promoted from meeting the requirements of indoor use to meeting the requirements of outdoor use, with good weather resistance, no fading, and stable flame retardancy. High-quality weather-resistant polyethylene materials are the future de...

AI Technical Summary

Problems solved by technology

However, because polyethylene molecules contain a small amount of double bonds and ether bonds, especially polyethylene materials added with flame retardants, their weather resistance is not good, and the sun and rain will cause polyethylene materials to age, so it is necessary to add antioxidants, Anti-UV agents and other additives for performance improvement
