AI Technical Summary

Problems solved by technology

However, many existing technologies are systems with anions, which cannot be transformed into cationic systems through simple formula adjustment.
[0006] 2. Particle design is unreasonable
It is mainly reflected in two aspects. First, although the synthesis process of enriching the fluorine-containing (meth)acrylate monomer in the shell is adopted, because the hydrophilicity of the shell is much smaller than that of the core, it is difficult to obtain the fluorine-containing (meth)acrylate monomer during the synthesis and storage process. There is a phase inversion, which affects the effect
Second, the shape of the core-shell is stabilized by cross-linking, but it will affect the enrichment of the fluoropolymer in the surface layer when the water and oil repellent film is formed, although sometimes this defect can be effectively improved by the "annealing" process , but requires a lot of time and energy and is not practical
[0007] 3. Poor waterproof and oil-proof performance and durability
From the practical point of view, such a design cannot meet the needs

Abstract

The invention relates to a water-proof and oil-proof agent composition and a preparation method thereof. The water-proof and oil-proof agent combination comprises a core-shell emulsion and a crosslinking agent with a weight percentage of 0.001%-15%. The core-shell emulsion comprises 20-30 percent of fluoropolymer, 0.001-48 percent of adjuvant and water. The crosslinking agent is polyisocyanate or an epoxy substance. The water-proof and oil-proof agent composition is applied to a textile, and has good water and oil prevention effect and excellent durability.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a water and oil repellent composition for textiles, a preparation method and application thereof. Background technique [0002] The water and oil repellency of textiles is usually obtained by finishing with water and oil repellent agents. See "Printing and Dyeing", Volume 21, Issue 12, 1995, pages 37-41, in the paper on fluorine-containing water and oil repellent (Ⅰ): the mechanism of water and oil repellency, the author Kubo Motoshin pointed out that water and oil repellents are generally It is a fluorine-containing polymer formed by copolymerization of fluorine-containing (meth)acrylate monomer and fluorine-free long-chain alkyl (meth)acrylate monomer as the main raw materials, plus a small amount of other monomers. [0003] Kubo Motoshin’s paper also introduced that the mechanism of water and oil repellent is to form a thin film on the outer surface of the substrate. The su...
