Abstract

The invention provides an environment-friendly water washing resistant waterproof agent and a preparation method thereof. The waterproof agent is characterized by comprising a hyperbranched polyestermodified compound, and has the molecular formula as shown in the description, A-OH is a hyperbranched polyester prepared from trimethylolpropane and 2,2-dimethylolpropionic acid through reactions, andx+y is less than or equal to the hydroxyl number of A. The preparation method comprises the following steps: preparing the hyperbranched polyester, preparing a half-addition product LDI-HEA, and performing modification on the hyperbranched polyester. The invention provides the environment-friendly water washing resistant waterproof agent and the preparation method thereof, and due to specific multi-active groups and a net-shaped structure of the waterproof agent, the waterproof agent is excellent in waterproof effect and water washing resistance.

Description

technical field

[0001] The invention belongs to the field of post-finishing of textile printing and dyeing auxiliaries, and in particular relates to an environment-friendly washable and waterproof agent and a preparation method thereof. Background technique

[0002] Entering the 21st century, human beings are facing major issues of environmental protection. All products that are harmful to the environment will be slowly replaced. At present, the leading products of fluorine-containing waterproof finishing agents on the market are still acrylate polymers containing perfluorinated long carbon chains (generally perfluoroalkyl acrylates containing 8 carbons). With the progress of research, people gradually found that perfluorooctanesulfonyl compound (PFOS) and perfluorooctanoic acid ammonium compound (PFOA) were contained in perfluorooctane sulfonyl compound (PFOS) and perfluorooctanoic acid ammonium compound (PFOA) in the acrylate polymer of perfluorinated long carbon chain gr...
