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, fabric face to be carried out clean, polarization processing or adopts the silane coupling agent of not only close adhesive but also close fabric to handle, all help improving adhesive to the adhesive strength between the fabric by the wetting capacity of fabric face and compatibility.The adhesive that has cross-linked structure or in solidification process, can form cross-linked structure has higher cohesive strength, thereby has improved the adhesive effect of adhesive to a certain extent.Aqueous polyurethane can be widely used as the coating of fabrics such as Nylon Taffeta, real silk, cotton, canvas, polyester-cotton blend, and the fabric behind top finish has functions such as Waterproof Breathable, soft surface, high resilience.Yet the domestic high-grade fabric finishing agent that is used to make industrial cloth such as garment material such as ski-wear, parka, jacket and tents, anti-oilcloth and is 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), IPDI (IPDI), hexamethylene diisocyanate (HDI) etc. are owing to TDI, MDI contain the rigidity aromatic ring; Make that the cohesive force of polyurethane is bigger; Have stronger TENSILE STRENGTH, the existence of aromatic ring can make glued membrane turn to be yellow easily, and TDI toxicity is big.IPDI also makes the intensity of polyurethane bigger owing to contain 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:, the invention provides a kind of preparation method of high hydrostatic pressure resistance anion aqueous polyurethane coating agent to the defective that prior art exists.
Technical scheme: for realizing the foregoing invention purpose, the present invention adopts following technical scheme:
A kind of preparation method of high hydrostatic pressure resistance anion aqueous polyurethane coating agent: may further comprise the steps: at first; The dibutyl tin laurate and the IPDI that in the agitated reactor of the dry cleansing that is full of inert gas, add organic solvent methyl iso-butyl ketone (MIBK), catalytic amount successively; After the heating for dissolving, obtain a liquid; Secondly, the PPG 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, and temperature control reaction 1 ~ 5h obtains prepolymer product, and in the prepolymer product that is obtained, adds composite end-capping reagent; Insulation reaction 1 ~ 5h; Obtain the polyaminoester emulsion of end-blocking, described composite end-capping reagent is by 1, and 4-butanediol and dihydromethyl propionic acid are formulated according to the mass ratio of 6-7:1; At last, add the triethylamine neutralizer of metering, regulate PH=6 ~ 9 to the reactant liquor device, deviate from organic solvent after, add neopelex, deionized water, high-speed stirred is to even, product.
The mass ratio of said 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 big 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.
