Description
Technical field
The present invention relates to textile auxiliary field, specifically a kind of composition of waterproofing and oil-proof agent used for textiles and its preparation method and application.
Background technology
The water and oil-resistant that textiles has normally arranges through water and oil repellent agent and obtains.See " printing and dyeing " nineteen ninety-five the 21st volume the 12nd phase 37-41 page, Fluorine-Contained Oil-Water-Proofing (I): in the paper about the mechanism of waterproof and oilproof performance, author's Kubo unit stretches and points out, water and oil repellent agent is generally fluorine-containing (methyl) acrylate monomer and floride-free chain alkyl (methyl) acrylate monomer is main raw material, adds the fluoropolymer of other monomer copolymerization a small amount of.
The paper stretched of Kubo unit is also introduced, and the mechanism of water and oil repellent agent effect is exactly form thin film at the outer surface of ground, and the surface tension of film lower than general liquid, thus shows and refuses water, refuses oil and anti-pollution function.The low-surface-energy of fluoropolymer itself is the reason that film surface tension force is low.Meanwhile, according to Surface Physical Chemistry principle, the superficial layer of film and extraneous contact, it determines capillary size with extraneous interaction, and the impact of film other parts effects on surface tension force outside desurfacing is very little.Thus, only need fluoropolymer to form superficial layer in waterproof and oilproof agent film, can low-surface-energy be obtained, obtain satisfied treatment effect.Under these conditions, if film other parts are not fluorine-containing, then can reduce the use of fluorine-containing (methyl) acrylate monomer.In addition, because fluorine-containing (methyl) acrylate monomer price is high, production process exists to be polluted and energy resource consumption, needs the consumption as far as possible reducing it.
Core-shell emulsion technology can pass through particle design, make the composition of emulsion particle sheath polymers different from interior nuclear polymer, after film forming, shell is in skin and the extraneous contact of film, kernel is in internal layer and is combined with textiles, kernel fluorine-containing (methyl) acrylate monomer concentration is significantly lower than shell, even do not add, so just can reduce fluorine-containing (methyl) acrylate monomer consumption.The document that this respect is delivered and patent are all a lot, but it is not enough more or less to there are following several respects.
1, specific aim is not strong.Owing to needing the most surface band negative electricity of textiles to be processed, need water and oil repellent agent to be cationic, just can have good effect.And existing technology is much the system of band anion, cationic system cannot be changed into by the adjustment of simple formula.
2, particle design is unreasonable.Be mainly reflected in two aspects, one, although adopt fluorine-containing (methyl) acrylate monomer at the synthesis technique of shell enrichment, because the hydrophily of shell is much smaller than core part, in synthesis and storage process, there is phase reversal, thus impact effect.They are two years old, by the crosslinked form stable making nucleocapsid, the enrichment of fluoropolymer when water and oil repellent agent film forming in superficial layer can be affected, although this defect effectively can be improved by " annealing " technique sometimes, but need a large amount of time and the energy, not there is practical significance.
3, waterproof and oilproof performance durability is poor.Both ways, one, water and oil repellent agent and fiber, particularly with the textiles of cotton composition, binding strength is poor in performance.Its two, most of prior art directly uses as water and oil repellent agent after preparation emulsion, obtains durability in self-crosslinking mode, and can add a small amount of crosslinking agent and improve further.From use practice, such design can not be satisfied the demand.
