Abstract

The invention provides a nanocomposite and a preparation method and application thereof. According to the nanocomposite provided by the invention, a nanomodified master batch is prepared from polyethylene, nanocalcium carbonate, ceramic nano particles, nanocellulose, a silane coupling agent, a first monomer, a second monomer and an initiator; since the nanocalcium carbonate and the ceramic nano particles are dispersed in the nano modified master batch, the nano modified master batch has good mechanical property; moreover, the silane coupling agent can enhance compatibility of the nanocalcium carbonate and the ceramic nano particles with a polyethylene material to realize a better dispersing effect; a nanocomposite with an intercalated structure is obtained by an in-situ graft intercalation technology; nano combination of polyethylene and an inorganic matter is realized, thus the mechanical property, heat resistance, aging resistance and the like of polyethylene plastic are effectively improved.

Description

technical field [0001] The invention belongs to the field of nano-modified composite materials, and relates to a nano-composite material and a preparation method and application thereof. Background technique [0002] Due to its light weight and non-toxicity, polyethylene has the advantages of excellent dielectric properties, chemical stability and corrosion resistance, and is cheap and easy to form and process. It can be widely used in electrical appliances, chemicals, food, machinery and other industries. With the continuous development of science and technology, higher requirements are put forward for the performance of polyethylene materials, and it is hoped that it will have more excellent mechanical properties and heat and aging resistance. Therefore, the modification of polyethylene is currently a research hotspot. [0003] CN 103881187 A discloses a nano-carbon fiber modified polyethylene material, the components of which are proportioned by mass percentage: polyethy...
