Abstract

The invention relates to an antibacterial low-VOC (low-volatile organic compound) PBT (polybutylene terephthalate) composite material and a preparation method thereof. The antibacterial low-VOC PBT composite material is prepared from components in parts by weight as follows: 60-80 parts of PBT, 4-6 parts of an antibacterial agent, 8-10 parts of VOC modified masterbatch and 0.1-0.5 parts of an antioxidant, wherein the antibacterial agent is a coral reef supported Ag<+> type antibacterial agent. A complex which is prepared from Ag<+> and 1-methyl-2-pyrrolidinone by adopting 1-methyl-2-pyrrolidinone as a stabilizer and 2-hydroxy-1-ethanethiol as a reducing agent is stably dispersed in the solvent, Ag<+> is reduced to zero valence from positive monovalence by 2-hydroxy-1-ethanethiol and is continuously gathered on a nucleus on the coral reef surface under the synergistic effect of 1-methyl-2-pyrrolidinone, and the coral reef supported Ag<+> type antibacterial agent is obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a low-VOC antibacterial PBT composite material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate (PBT) is an important thermoplastic material, which is widely used in the fields of automobiles, household appliances, mechanical parts, office supplies and communication equipment. PBT material has the advantages of light weight, non-toxic, odorless and good water absorption. In some specific material application fields, there are not only requirements for antibacterial performance of PBT materials, but also high requirements for VOC performance, which cannot be met by ordinary PBT materials. [0003] In view of this reason, this technical solution innovatively produces a PBT composite material with excellent antibacterial performance and good VOC performance. This material has not been reported so far, which has very important prac...
