Abstract
The invention discloses a preparation method of an anionic waterborne polyurethane coating agent with high resistance to hydrostatic pressure, which comprises the following steps: firstly, orderly adding an organic solvent of methyl isobutyl ketone, IPDI and dibutyl tin dilaurate with a catalytic amount into a dry and clean reaction vessel which is full of inert gas, heating to dissolve so as to obtain a solution a; secondly, mixing certain amounts of polyether polyol and methyl isobutyl ketone, dissolving to obtain a solution b; then slowly and dropwisely adding the solution b into the solution a, reacting at a controlled temperature for 1-5 hours to obtain a pre-polymerization product; finally, performing terminal blocking, neutralization, and organic solvent removal in order, adding sodium dodecyl benzene sulfonate and deionized water, stirring at a high speed till the mixture is uniform to obtain the product. The product obtained by the invention has high bonding fastness and high strength, is applicable to fabric finishing, has good handle, is safe, nontoxic, and environment-friendly; and the process operations are simple. The indexes of both hydrostatic pressure resistance and soaping fastness reach the level of import high-grade waterborne PU fabric coating agents.
Description
Technical field:
The present invention relates to a kind of high hydrostatic pressure resistance anion aqueous polyurethane coating agent, particularly the preparation method of high hydrostatic pressure resistance anion aqueous polyurethane coating agent.
Background technology:
In order to improve adhesive and by the wetting capacity of fabric face and compatibility, fabric face to be carried out cleaning, polarization processing or adopts the silane coupling agent of not only close adhesive but also close fabric to process, all be conducive to improve adhesive to the adhesive strength between fabric.The adhesive that has cross-linked structure or can form cross-linked structure in solidification process has higher cohesive strength, thereby has improved to a certain extent the adhesive effect of adhesive.Aqueous polyurethane can be widely used as the coating of the fabrics such as Nylon Taffeta, real silk, cotton, canvas, polyester-cotton blend, and the fabric after top finish has the functions such as Waterproof Breathable, soft surface, high resilience.Yet domestic high-grade fabric finishing agent for making the industrial cloth such as the garment material such as ski-wear, parka, jacket and tents, anti-oilcloth and being used for the BLENDED FABRIC wool-like finishing still needs a large amount of external imports that rely on.
Polyisocynate monomer commonly used mainly contains 2,4-dimethyl vulcabond (TDI), 4,4 '-'-diphenylmethane diisocyanate (MDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI) etc., because TDI, MDI contain the rigidity aromatic ring, make the cohesive force of polyurethane larger, have stronger TENSILE STRENGTH, the existence of aromatic ring can make glued membrane easily turn to be yellow, and TDI toxicity is large.IPDI also makes the intensity of polyurethane larger owing to containing alicyclic ring, has excellent yellowing resistance, and weatherability is nontoxic.And HDI does not contain circulus, and intensity is less, but its structure is more regular, makes the polyurethane adhesive membrane crystallization.
Summary of the invention:
Goal of the invention: for the defective that prior art exists, the invention provides a kind of preparation method of high hydrostatic pressure resistance anion aqueous polyurethane coating agent.
Technical scheme: for achieving the above object, the present invention by the following technical solutions:
A kind of preparation method of high hydrostatic pressure resistance anion aqueous polyurethane coating agent: comprise the following steps: at first, the dibutyl tin laurate and the IPDI that add successively organic solvent methyl iso-butyl ketone (MIBK), catalytic amount in the reactor of the dry cleansing that is full of inert gas, after heating for dissolving, obtain a liquid; Secondly, polyether polyol PPG-2000 and the methyl iso-butyl ketone (MIBK) of metering is miscible, obtain b liquid; Then, b liquid slowly is added drop-wise in a liquid, temperature control reaction 1 ~ 5h obtains prepolymer product, and add composite end-capping reagent in the prepolymer product that obtains, insulation reaction 1 ~ 5h, obtain the polyaminoester emulsion of end-blocking, described composite end-capping reagent is formulated according to the mass ratio of 6-7:1 by BDO and dihydromethyl propionic acid; At last, add the triethylamine neutralizer of metering to the reactant liquor device, regulate PH=6 ~ 9, after deviating from organic solvent, add neopelex, deionized water, high-speed stirred gets product to even.
The mass ratio of described IPDI and PPG-2000 is 1 ~ 5:1.
According to above technical scheme, can realize following beneficial effect: compared with prior art, the present invention has the following advantages: it is large that the present invention obtains high hydrostatic pressure resistance anion aqueous polyurethane coating agent bonding intensity, intensity is high, be applied to textile finishing, good hand touch, safety non-toxic, environmental friendliness, technological operation is simple.Its resistance to hydrostatic pressure and fastness to soaping index have all reached the level of the high-grade water-based PU of import textile coating agent.
The specific embodiment:
Below in conjunction with embodiment, the present invention is done further describing in detail, but the scope of protection of present invention is not limited to the scope that embodiment represents.
Embodiment 1:
In the drying that is full of nitrogen or inert gas, add organic solvent methyl iso-butyl ketone (MIBK) (100.0kg) and IPDI(300.0kg) in the reactor of cleaning, catalyst dibutyl tin laurate (1.05kg) is heated to 60 ℃ of dissolvings under stirring, stand-by;
Take PPG-2000 (285.0kg) and methyl iso-butyl ketone (MIBK) (70.0kg), after mixing, be added dropwise in above-mentioned reactor, control temperature at 90 ~ 105 ℃, reaction 1 ~ 5h, reaction is finished, add 1 in product, 4-butanediol (115.0kg) and dihydromethyl propionic acid (17.5kg) react 1 ~ 5h, obtain the polyaminoester emulsion of end-blocking;
Add neutralizer triethylamine (10.5kg) in above-mentioned reactant liquor, regulate PH=6.8, reaction 1 ~ 2h, solvent is deviate from decompression, add neopelex (2.5kg), deionized water (1340.0kg), high-speed stirred is to even, cooling encapsulates to get high hydrostatic pressure resistance anion aqueous polyurethane coating agent product.
