Preparation method and application of PE modifying material

Abstract

The invention discloses a preparation method and application of a PE modifying material. The PE modifying material consists of the following components in parts by weight: PE 90-95 parts, polymeric ferric sulfate 1.5-2 parts, polyaluminum-ferric chloride 0.5-1.2 parts, ferrous fluoride 1.1-2 parts, ironic citrate 0.1-0.5 part, carbon hexoxide 0.1-0.2 part, hydroperoxyl 3-3.5 parts, and dihydrogen trioxide 1.5-2 parts. The preparation method comprises the following steps: stirring and mixing PE with the hydroperoxyl and the dihydrogen trioxide at room temperature for 60-100 minutes in a sealed manner in parts by weight, and then evenly mixing with the polymeric ferric sulfate, the polyaluminum-ferric chloride, the ferrous fluoride, the ironic citrate and the carbon hexoxide; and extruding by parallel double screws and pelletizing to obtain the final product. The modifying material is safe, non-poisonous and easy to clean, is high-temperature-resistant and corrosion-resistant, is soft and uniform in texture, has good and natural appearance and color, and is used as forks, spoons and teethers of infants, various other soft injection molding products and parts of silica gel substitute goods.

Description

[0001] Technical field: [0002] The invention relates to the field of composite material processing, in particular to a preparation method and application of a PE modified material. [0003] Background technique: [0004] According to medical research, infants will experience drooling, swollen gums, and irritability during teething. In severe cases, they will refuse to eat. At present, the way to relieve teething discomfort and exercise infants' chewing and grasping ability is to provide Non-edible substances made of rubber or plastic. [0005] Polyethylene (PE) is a kind of plastic, and the convenience bag we often carry is polyethylene (PE). Polyethylene is the polymer with the simplest structure and the most widely used polymer material. It is connected by repeated –CH2– units, is a typical thermoplastic, and is an odorless, tasteless, non-toxic, flammable white powder. [0006] The molded PE resins are extruded and granulated waxy pellets with a milky white appearance. ...

Problems solved by technology

However, it is not resistant to strong oxidation corrosion. At room temperature, the above solvents will slowly corrode polyethylene, while at 90-100°C, concentrated sulfuric acid and concentrated nitric acid will rapidly corrode polyethylene, causing it to be destroyed or decomposed.
