Description
Technical field
The present invention relates to a kind of perfluoroalkyl polyolefin acid ester waterproofing agent, preparation method and applications, be specifically related to one and contain
Sulfur long heterochain perfluoroalkyl polyolefin acid ester emulsion and preparation method thereof, and it is applied to fabric waterproof Final finishing, belong to fine chemistry
Product and weaving auxiliary chemicals field.
Background technology
People find during studying the waterproof oil-proof finishing of fabric, with containing fluoroalkyle compound to fabric
Carry out processing and can give the waterproof new energy that fabric is excellent.Through the research and development of decades, fluorine-containing textile finishing agent commodity
Changing and occupy the biggest market, the development of these fluorine-containing textile finishing agents is greatly enriched the research field of organic fluorine material,
And become one of them important branch, obtain the very big concern of domestic and international researcher.
Nineteen fifty, Du Pont company of the U.S. takes the lead in using using politef (PTFE) emulsion as fabric finishing agent,
And applied for patent.Nineteen fifty-three, Minnesota Mining and Manufacturing Company succeeds in developing with perfluorocarboxylic acid chromium complex CF3(CF2) nCO2CrOH is main
The fabric finishing agent of body, the effective ingredient of this kind of waterproof oil-repellent agent of little molecule-type can be also the quaternary ammonium compound of perfluor amide, as
CF3(CF2)6CONH (CH2) 3N+(CH3)2C2H5Br-.But, owing to washing fastness is poor, they are quickly preferably contained by performance
Fluoroacrylate polymer is replaced, as 3M Developed in 1956 with " Scotchgard FC2208 " as representative
The effective ingredient of FC series fabric finishing agent is fluorine-containing olefine acid ester polymer.
Fluorine-containing olefin(e) acid esters polymer can provide waterproof functional oil of refusing to have benefited from the fluoroalkyl on its side chain, these fluoroalkyls
Protect with zigzag chain conformation and shield main polymer chain so that polymeric film has low-surface-energy, thus provides excellent preventing
Water refuses functional oil.Wherein, perfluoro capryl polyacrylate is proved to be to provide the fabric of the most superior waterproof oil repellency whole
Reason agent, thus obtain extensively application.But, more and more study confirmation, carbon chain lengths is complete equal to or more than 8 carbon atoms
Fluoroalkyl in most of environmental conditions are tested all without hydrolysis, photodissociation or biodegradation, these long carbon chain perfluor alkyl occur
The root that be proven with persistent environments inertia and bioaccumulation toxicity, environment can be worked the mischief.European Union member countries are at present
Through completely forbidding perfluorinated octyl sulfuryl amine derivant (PFOS) the class finish materials producing and using containing Long carbon chain fluoroalkyl
And derived product.
When using the carbon chain lengths short carbon chain fluoroalkyl less than 8 as side base, the fluoropolymer obtained then can drop naturally
Solve.In recent years the synthesis having emerged in large numbers many short fluorocarbon chain compounds both at home and abroad is reported with applied research, and research finds, due to fluorine film table
The short carbon chain perfluoroalkyl rigidity in face is little, nodeless mesh, it is impossible to form stable liquid crystal structure arrangement, the short carbon chain halothane constructed
Base protecting film fluorocarbon chain Duan Yi after contact liq redirects, topples over, and easily makes basal body structure expose so that the shielding of fluorine film is lost
, i.e. there is so-called short carbon chain perfluoroalkyl " surface reconstruction ", thus cause side base end trifluoromethyl (-CF in effect3) layer suffers
Destroy and even cave in, thus do not reach effective liquid repellent function.

The contradiction of liquid poor effect, it is provided that a kind of sulfur-bearing long heterochain perfluoroalkyl olefine acid ester polymer waterproofing agent, it is thus achieved that polymer contain
Perfluoroalkyl long heterochain side base, is prone to degraded, there is not cumulative toxicity because side base contains thia key, is not belonging to disable fluorine-containing
Chemicals.Meanwhile, long heterochain perfluoroalkyl has again crystallinity and rigidity so that fluoropolymer surface conformational stability, thus
There is superior liquid repellent function.This finishing agent is applied to Cotton Fabric and can obtain the most excellent waterproof effect.
