Abstract

The present invention relates to a kind of comprising at least one blocked polyisocyanates and at least one oleophobic property and/or the preparation of Hydrophobicity Finishing agent, and is related to purposes of the preparation for the oleophobic property and/or Hydrophobicity Finishing of sheet material, particularly textile.

Description

Finishing agent with blocked polyisocyanates
The present invention relates to include at least one blocked polyisocyanates and at least one oleophobic property and/or Hydrophobicity Finishing agent Preparation, and be related to the preparation for the oleophobic property of fabric, particularly textile and/or the purposes of Hydrophobicity Finishing.
Water repellent effect or refuse oily effect to generate to textile, generally using based on organopolysiloxane, polyurethane, change Property melamine resin, wax, paraffin and/or fluorocarbon polymer preparation.
And silicic acid anhydride only may be implemented with no fluoride preparation, oil repellent can also be provided containing fluoride preparation.Fluorine based formulation Hydrophobicity and oleophobic property arrangement are typically based on fluorocarbon polymer, particularly polyurethane-or poly- (methyl) propylene containing perfluoroalkyl Acid esters system.
Usually used poly- (methyl) acrylatcs systems have perfluoroalkyl (methyl) acrylate monomer structure.Due to These monomers are telomerisation process as a result, so substantially using with different chain length (C4-C10) perfluoroalkyl it is residual The mixture of the monomer of base.It is preferable to use the lists for the perfluoroalkyl residue for having average eight carbon atoms for aforementioned monomer mixture Body mixture.
However, having been carried out recently due to ecological and/or toxicological concerns using at most there are six the complete of carbon atom The conversion of the fluorinated monomer structural unit (building block) of fluoroalkyl residue.For example, in EP 2057201 and EP In 1298180, such monomer or polymer are described.
Other than perfluorinated monomer, such as C12-22-Alkyl (methyl) acrylate, vinyl chloride, vinylidene chloride and/or benzene The non-fluorinated comonomers such as ethylene are used for the synthesis of oleophobic property and hydrophobic agents.In addition, using being total to comprising crosslinkable groups Polycondensation monomer.Crosslinkable groups can be reacted with fabric and/or external crosslinker (multifunctional key) to be arranged.
For the polyurethane system of oleophobic processing and silicic acid anhydride by fluorine telomer alcohol (fluortelomer Alcohol it) produces.Herein, polyisocyanates or the prepolymer comprising isocyanate group are reacted with fluorine telomer alcohol.
Based at most there are six poly- (methyl) both the acrylate and polyurethane system of the monomer of perfluocarbon atom Prove compared with the preparation based on the monomeric building blocks for averagely there are eight perfluocarbon atoms, have lower influence horizontal (effect level).This, which may be attributed to perfluorinated C6- alkyl residue, has the fact that less significant crystallization behavior.
Other than fluorine-containing system, hydrophobic effect is also made it possible to achieve without realization oleophobic effects without fluoride preparation. As a result, usually using the aqueous emulsion of lyophobic dust.These may include, for example, polyethylene, paraffin, Fischer-Tropsch wax or metallic soap. Also such as Brazil wax, beeswax or lanolin natural oil lipid and wax class can be used.As a result, from known to DE 10211549 By synthesizing or native paraffin component (for example, beeswax, Brazil wax, polyethylene wax or Fischer-Tropsch wax) and super branched polyurethane constitute Preparation.Particularly preferred linear paraffin.It is described in DE 102007020790 and replaces the similar of wax component comprising organopolysiloxane System.
In DE 1017133, describe comprising hexamethylolmelamine hexamethyl ether condensation product, stearic acid, tristearin The hydrophobing agent of the mixture of acid triglyceride and triethanolamine and paraffin.
It it is known that the method by making textile carry out silicic acid anhydride using crosslinkable organopolysiloxane.For example, As recorded in US 4098701, with the help of catalyst, pass through the contracting of the organopolysiloxane of Si-H- and Si-OH- function Conjunction can crosslink.(joined by being crosslinked for olefinic residue addition for being bonded the organopolysiloxane of Si-H- function with SiC- See US 4154714 and DE 3332997) it is also possible.However, due to the response characteristic of organopolysiloxane, production The preparation of stable upon storage is difficult.In general, can only before the use at once mix component, this is actually using them Middle inconvenience.
EP 2152957 describes the free-floride based on organopolysiloxane and polyurethane of the water repellent finish for textile Carbon polymer preparation.
The oleophobic hydrophobing agent of above-mentioned textile is usually formulated together with arrangement blocked polyisocyanates.In sealing end isocyanide In the case where acid esters, reactive isocyanate base is reacted with blocking group, to notice the (example under common storage requirement Such as, 0 to 80 DEG C) isocyanate group do not react.For example, by raised temperature (referred to as unblock temperature, for example, > 80 DEG C) Under activate blocked isocyanate, blocking group can be separated with the isocyanate group generated again.The isocyanate group energy of acquisition Hydrophobing agent is enough set to be crosslinked or be bonded to textile substrate, wherein point when crosslinking or bonding can live according to being expected that by adjust Change condition selects.The influence level arranged in this way as a result, can significantly improve, and wearability and washing fastness are significant It improves.
For making the polyisocyanate blocked most important compound diacetylmonoxime and 3,5- diformazan for textile industry Base pyrazoles.In the case where diacetylmonoxime, mainly block aromatic polyisocyanate, since gained system still has for arranging The acceptable unblock temperature of agent.However, the shortcomings that aromatic compound is the strong tendency that they make textile turn to be yellow.This Outside, diacetylmonoxime is classified as potential carcinogen, it is meant that when it is applied and activates, it is necessary to be arranged using corresponding safety precautions It applies.
Selectively, 3,5- dimethyl pyrazole is used as end-capping reagent, it is especially suitable for aliphatic polyisocyante classes.Separately On the one hand, aromatic polyisocyanate class is seldom blocked by 3,5- dimethyl pyrazole, because in this case, in order to obtain The aqueous formulation of ambient temperature stable, so that unblock temperature is too low.3,5- dimethyl pyrazole is also suspected harmful to health.
In DE 69927679, the polyisocyanates of self-dispersing pyrazole derivatives sealing end are disclosed, with effect oleophobic Auxiliary agent when property and/or Hydrophobicity Finishing agent finishing fiber material.In order to ensure the dispersibility of blocked polyisocyanates, these packets Group containing hydrophilic polyalkylene oxide.The shortcomings that system of record is hydrophilic radical, offsets the desired water repellent effect of compound. In addition, disadvantage is the blocking group 3 used, 5- dimethyl pyrazole, with high fusing point and boiling point, it is meant that in order to ensure spinning End-capping reagent is not remained on fabric, it is necessary to dry under very high thickening temperature or concentration.Since 3,5- dimethyl pyrazole is cherished It is suspected to be teratogenesis, so this should be avoided.However, studies have shown that substantially residual is few residual on the textile arranged in this way The 3,5- dimethyl pyrazole of allowance.
EP 2599848 describes water repellent and refuses fluid composition, and it includes the polyisocyanates of pyrazoles sealing end, nonionic Surfactant and water repellent and refuse oil ingredient.As described above, it is necessary to avoid the end-capping reagent containing pyrazoles of any kind.
EP 1375552 describes the aqueous or water-thinned polyisocyanates blocked with secondary benzyl amine and is used as drying Crosslinking agent in coating (stove enamel).Blocked polyisocyanates include hydrophilic radical, so as to make compound exist It emulsifies or disperses in water.Cation, anion and/or non-ionic group are introduced to the polymerization as hydrophilic agent in large quantities In object.Such system is not suitable for use in the silicic acid anhydride crosslinking agent of textile, strong moistens again because hydrophilic radical is shown Wet effect, it is meant that can not achieve desired water repellent effect.
EP 1375551 describe as self-crosslinking single component drying (stoving) system with secondary benzyl amine block Polyisocyanates.
