Abstract

According to the antibacterial durable PE composite particle disclosed by the invention, carbon black and an inorganic metal antibacterial agent are replaced by nano-modified bamboo charcoal plastic particles, so that the PE composite particle has good anti-aging and antibacterial properties and is more durable; the nano modified bamboo charcoal plastic particles are prepared from the nano titanium dioxide-zinc dioxide composite powder and the nano bamboo charcoal powder, and the bamboo charcoal is rich in potassium, sodium, calcium, aluminum, manganese and other metal elements and carbides thereof, especially calcium carbide, so that the nano modified bamboo charcoal plastic particles have favorable ultraviolet resistance. Titanium dioxide and zinc oxide are two common inorganic ultraviolet shielding agents, but the shielding capacities of the two inorganic shielding agents are different, the UVB blocking effect of nano titanium dioxide is very good, but the UVA shielding effect is poor; and the shielding effects of the nano zinc oxide are opposite. Therefore, the nano-modified bamboo charcoal plastic particles have triple anti-ultraviolet effects.

Description

technical field [0001] The invention relates to the technical field of PE particles, in particular to an antibacterial and durable PE composite particle. Background technique [0002] PE is the simplest polymer organic compound and the most widely used polymer material in the world today. It is made of ethylene. PE pipes made of PE materials have comprehensive advantages such as safety, sanitation, convenient construction, and long service life. , are widely used in building water supply, building drainage, buried drainage pipes, building heating, gas pipelines, electrical and telecommunications protection casings, industrial pipes, agricultural pipes, etc. [0003] The patent No. CN107254090A discloses a modified PE recycled plastic granule and its preparation process. Compared with ordinary recycled PE plastic granules, the flame retardant performance of the PE recycled plastic granule is significantly improved, but the PE granule still has the following defects : Poor an...
