Problems solved by technology

[0004] The compatibilizer described in Chinese patent application CN101981070A is a low molecular weight monomer, which cannot guarantee the continuity of monomer compatibility
[0005] In Chinese patent application CN1703481A and Chinese patent application CN101668826A, the problem of compatibility between monomer combinations is not considered
Although the Chinese patent application CN101486823A uses this type of surfactant, its dosage is relatively small, the total surfactant dosage is not much reduced, and the waterproof and oil-proof performance is not greatly improved.
Some types of fluorine-containing (meth)acrylate monomers have poor compatibility with non-fluorine monomer monomers, and random copolymerization between monomers cannot be effectively carried out, thereby affecting performance. The existing technology cannot solve this problem
[0010] Third, in the scheme of conventional surfactants used in water and oil repellents or conventional surfactants combined with a small amount of gemini surfactants, the amount of surfactants is large, which affects the waterproof and oil repellent performance

Abstract

The invention provides a water and oil proofing agent, and a preparation method and applications thereof. The water and oil proofing agent comprises following ingredients, by mass, 20 to 30% of a polymer containing fluorine, 3 to 20% of a compatilizer, 1 to 5% of a surfactant, 4 to 20% of a hydrophilic solvent, 0.001 to 3% of a pH adjusting auxiliary agent, and water. The water and oil proofing agent possesses excellent water and oil proofing effect, is green, and is friendly to the environment. Compared with existing products, water and oil proofing effect of compounds containing fluorine is more obvious in the water and oil proofing agent, and influences of the surfactant on water and oil proofing performance are reduced.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to an environment-friendly waterproof and oil-repellent agent for textiles, a preparation method and application thereof. Background technique [0002] Many fields require textiles to have waterproof and oil-repellent performance, and the waterproof and oil-repellent effect is usually obtained by finishing with waterproof and oil-repellent agents. Water and oil repellents are "generally made of fluorine-containing (meth)acrylate monomers and long-chain alkyl (meth)acrylate fluorine-free monomers as the main raw materials, plus a small amount of other monomers copolymerized." (Jiubo Yuan Shen, Fluorine-containing water and oil repellent (Ⅰ): Mechanism of water and oil repellency. Printing and Dyeing, 1995, 21 (12): 37-41) At present, many water and oil repellents use these substances as raw materials, after emulsion In the aqueous product obtained by polymerization, the carbon num...
