Abstract

The invention discloses an adsorption type polyethylene plastic composite material which is prepared from, by weight parts, 40-49 parts of linear low density polyethylene, 10-15 parts of crosslinked modified starch, 3-8 parts of polyethylene glycol, 3-6 parts of nano calcium carbonate, 3-7 parts of acetylene carbon black, 2-5 parts of ceramic fiber, 1-3 parts of activated carbon, 2-4 parts of silver alginate nanofiber, 4-6 parts of apple pectin, 5-8 parts of nano-bentonite, 2-3 parts of modified phosphogypsum whisker, 2-5 parts of nano-titanium dioxide, 2-3 parts of toughening agent, 1-3 partsof surfactant and 2-5 parts of chitosan. The adsorption type polyethylene plastic composite material is low in cost and further has excellent antibacterial property and electrical conductivity, hightensile strength and good mechanical strength and adsorption performance.

Description

technical field [0001] The invention relates to the field of plastic packaging, in particular to an adsorption type polyethylene plastic composite material. Background technique [0002] Plastic is a cheap and high-quality material. However, with the widespread use of plastic bags and plastic thin products, it has been found that the intrinsic life of plastic thin products is much longer than its service life. The inherent durability of plastics increases the proportion of urban solid waste, and the discarded plastic thin products (such as plastic bags, plastic packaging, disposable plastic products, mulch, etc.) pollute the environment for a long time, and gradually become White pollution has become one of the major problems plaguing human survival and development in the 21st century. [0003] In order to reduce white pollution and protect the ecological environment, the research, development and use of biodegradable plastics are becoming more and more important and urgent...
