Abstract

The invention relates to a high-molecular electret material, in particular to an ethylene binary copolymer, a polyethylene melt-blown material and a preparation method. The ethylene binary copolymer is a binary polymer of ethylene wax and 2-allylhexafluoroisopropanol, and has the shownstructural formula . The preparation method comprises the following steps: mixing the polyethylene wax and the 2-allylhexafluoroisopropanol under the effect of the initiator and the antioxidant, and reacting, melting and extruding to obtain the product. The copolymer can be used as a compatilizer to improve the compatibility between polyethylene / inorganic electrets, and a large amount of fluorine element contained in poly (2-allylhexafluoroisopropanol) can play an organic electret role in a polyethylene melt-blown material and improve the thermal stability of the polyethylene melt-blown material. After the ethylene binary copolymer is added into the polyethylene-based composite material, the effects of capacity increase, electret and aging resistance improvement can be achieved, and the ethylene binary copolymer has a wide potential application prospect in polyethylene melt-blown materials.

Description

technical field

[0001] The invention relates to a polymer electret material, in particular to an ethylene binary copolymer, a polyethylene melt blown material and a preparation method. Background technique

[0002] Polypropylene melt-blown cloth tends to turn yellow and become brittle after irradiation, while there are no tertiary carbon atoms in the polyethylene structure, so the aging resistance of polyethylene melt-blown materials is better than that of polypropylene. Toxic oxides are likely to remain in melt-blown polypropylene, which poses a potential threat to human health. In addition, compared with melt-blown polypropylene, melt-blown polyethylene has a higher melt index, lower melting point and better softness, and is suitable for baby diapers, wet wipes, work clothes, filter materials and other fields. In order to improve the electret and filtration performance of polyethylene melt blown cloth material, it is necessary to add organic electret material or inorganic...
