Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a melting-expanded electret antibacterial master batch and a processing technology and application thereof. The master batch comprises the following components in parts by weight: 70-190 parts of polypropylene, 1-2 parts of a peroxide, 1-2 parts of an antioxidant, 1-2 parts of a plasticizer, 1-2 parts of a lubricant, 1-2 parts of an electret material and 1-2 parts of an antibacterial agent. The master batch has multiple functions, molecular weight breakage is caused by adding peroxide, the meltindex of the PP material is increased, the flowing property of the material is improved, and the material is easier to form. The electret material is added, so that the material can generate static electricity to adsorb viruses and particulate matters in air, and due to the antibacterial and bactericidal material in the material, the viruses and the particulate matters can be adsorbed to kill germs. Only a small amount (about 4%) of the material is added into a medium-melt-index fiber-grade PP raw material (only non-woven fabric can be used in the past), and the material can be applied to a melt-blown material, so that the problem of shortage of the melt-blown material is solved.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and in particular relates to an expanded fusion electret antibacterial masterbatch, its processing technology and application. Background technique

[0002] At present, due to the spread of the coronavirus, the market demand for masks and related materials has greatly increased. The current PP melt-blown materials have the following problems. The function is single, and the output cannot meet the market demand. The PP raw materials of Zhongrong Finger Fiber produced in the past can only be used Due to the production of non-woven fabrics, it is impossible to meet the requirements of the filtration effect of melt-blown materials for mask production. The output of melt-blown materials that meet the requirements of filtration effects is insufficient and the price is extremely high, which cannot meet the needs of the market.
