The invention relates to a low VOC (Volatile Organic Compound) regenerated polyester fiber and a preparation method thereof. The preparation method comprises the following steps: melting and blendingregenerated polyester melt prepared by alcoholysis and polymerization of regenerated polyester raw materials with a masterbatch in which VOCs are removed, and then spinning to obtain the low VOC regenerated polyester fiber. The masterbatch in which the VOCs are removed is prepared from the following components in percentage by mass: 60 to 75 percent of polyester, 10 to 15 percent of aldehyde inhibitor modified activated carbon, 12 to 19 percent of rare earth element doped photocatalyst, 2 to 4 percent of heat stabilizer, 2 to 4 percent of ether-proof agent and 1 to 2 percent of zinc stearate.The final low VOC regenerated polyester fiber in the absence of light has the characteristics that the removal rate of aldehyde VOCs is greater than or equal to 80 percent and the removal rate of benzene VOCs is greater than or equal to 30 percent; under the existence of light, the removal rate of the aldehyde VOCs is greater than or equal to 85 percent and the removal rate of the benzene VOCs isgreater than or equal to 60 percent. The preparation method disclosed by the invention has the advantages of simple production process, low VOC content of a product and great application prospect.

The invention relates to the field of coatings, and discloses a water-based polyamide-imide anti-corrosion non-stick coating and a preparation method thereof, comprising: 30-60 parts of fluororesin emulsion, 20-40 parts of PAI emulsion, and 15- parts of anti-corrosion filler 30 parts, 10-20 parts of pigments, 1-5 parts of additives, 1-5 parts of pH adjuster, and 10-30 parts of water. In the present invention, PAI resin is first prepared, and then anionic surfactant and nonionic surfactant are used as emulsifiers to prepare PAI emulsion with good stability by a phase inversion method. A composite resin is formed with PAI emulsion and fluororesin emulsion, and a flaky or scaly anti-corrosion filler is added to the composite resin to obtain a polyamide-imide anti-corrosion non-stick coating. The anti-corrosion filler and the bonding resin can form a dense coating. layer, which can effectively enhance the corrosion resistance of the coating film.
