One Chinese patent application numbers 200710017130.6 discloses " a kind of organic fluorine water-refusing oil-refusing finishing agent and preparation thereof "; This emulsion is obtained through emulsion polymerisation in the presence of emulsifying agent, assistant for emulsifying agent, chain-transferring agent, initator by assorted oxygen perfluoroalkyl (methyl) acrylate monomer, higher aliphatic (methyl) acrylate monomer, cross-linking monomer, is used for the water and oil repellent finish of fabric.
One Chinese patent application numbers 200810163363.1 discloses " a kind of organosilicon fluorine multifunctional fabric finishing agent and preparation method thereof "; In organic silicone finishing agent; Introduce a spot of Organic fluoride group; Do not changing under the former situation about producing effect of organic silicone finishing agent, further improving the smooth property of finishing agent, also increasing the effect of water and oil repellant simultaneously to a certain extent.
Summary of the invention
The object of the invention aims to provide a kind of oil repellent finish of fabric that is used for textiles.
Oil repellent finish of fabric of the present invention, its each contain the composition of following weight in rising: acrylic acid fluorohydrocarbon ester resin 30-50g, thickener 1-3g, water-soluble organic silicon 3-5g, triethylamine 0.9-2.5g, remaining is a water.
Above-mentioned acrylic acid fluorohydrocarbon ester resin is an existing product, has commercially available; Above-mentioned thickener is gelatine, acrylic acid, can add separately, also can add jointly; Above-mentioned organic silicon water soluble is the feel improver; Above-mentioned triethylamine is a catalyst; Above-mentioned water is better with deionized water, and deionized water can prevent well that Organic fluoride and the complexing of calcium magnesium salts from making arrangement coarse, and described deionized water is meant the water of removing metal ion.It is between 4.5 to 5.5 that finishing agent of the present invention requires PH, can regulate with conventional method, as adding NaOH.
Above-mentioned acrylic acid fluorohydrocarbon esters resin polymerisation becomes following frame structure:
It refuses water and to be prone to deoiling property relevant with carbochain length, and the short more oil repellent of carbochain is good more.
Above-mentioned acrylic acid fluorohydrocarbon esters resin except the hydrophobic chain that contains perfluoroalkyl, also contains hydrophilic segment such as hydroxyl, carboxyl, polyether-based in the molecular structure of its polymer.The chemical constitution of this perfluorochemicals is compared with the product such as the acrylic acid fluorocarbon sulfonamides base Arrcostab of perfluoroalkyl sulfonyl compound; Lacked sulfoamido; Do not see its report so far to environment and human health damage, and its refuse oil similar with easy detergency ability with the perfluoroalkyl sulfonyl compound.Fluorine-containing groups directional profile in the resin segment of arrangement back is in the cloth cover upper strata, and hydrophilic segment then under the mesh resin surface, shows the waterproof oil repellent; But hydrophilic segment is distributed on the surface after fabric changes in the water, and hydrophobic segment is distributed in the surface down, thereby improves wettability, helps washing the back decontamination; After the oven dry, the distributing position of two kinds of segments is kept in the center again, produces oil repellent again.
The selection of thickener in the present invention is very crucial.At first to select not have the auxiliary agent of affinity, not have ionic reaction, no bonding conditions with acrylic acid fluorohydrocarbon esters resin; Body lotion does not produce complex reaction; Thickener and fiber can not be crosslinked, and be water-soluble with bonding and tool by branch, can when post processing, wash the auxiliary agent of removing.Applied amount is so that the resin working solution is evenly coated product surface, and not lost because of dewatering, and can stop the preceding resin migration of oven dry again is purpose.Adhesive attraction with thickener makes resin be able to evenly be coated on fiber surface, is that unique fabric is successfully refused oily decontaminable key.This thickener promptly can not have living chain again can not with resin crosslinks, easier eccysis property must be arranged.To reticulate the macromolecular chain reaction of structural membrane be very slowly to resin-shaped in addition; The cross-linked polymeric of simple resin wanted 90 minutes just can reach resin conversion ratio 100% under 140-150 ℃ temperature; And discover that fluorohydrocarbon ester resin can play fabulous catalytic action under the effect of basic salt; As when triethylamine exists under equal conditions only 3 minutes resin conversion ratios can reach 98%; The effect of triethylamine in the present invention is the into acrylic acid fluorohydrocarbon ester resin self-crosslinking reaction speed of urging, and reduces the required temperature of reaction.
Oil repellent finish of fabric of the present invention is to utilize fluorine resin that the product of super-fine fiber material is carried out functional soil-releasing finiss, prevents that greasy dirt from staiing the infiltration and the associativity of product, to improve product specification and functional.
The present invention is mainly used in the post processing of superfine fibre; Make the superfine fibre product behind process functional treatment of the present invention; Make fluorine resin perhaps avenge the Neil circle and on the spot form layer protecting film in the blanket surface at superfine fibre; Make spot can not penetrate into fibrous inside, but among fiber surface coats.Thereby, reach the effect of anti-oil.The present invention not only has good anti-oil and is prone to dirt-removing functions, and handled product is soft.
