Abstract
The invention discloses a preparation method for environmentally-friendly coating printing adhesive, which comprises the following steps: (1) adding organic solvent N-methyl pyrrolidone, isophorone diisocyanate (IPDI) and dibutyltin dilaurate of the catalytic amount in a reaction kettle filled with inert gas, heating, and dissolving to obtain liquid a; (2) dissolving metered polyethylene glycol (PEG)-600 and trimethylolpropane into a proper quantity of N-methyl pyrrolidone to obtain liquid b; (3) slowly dripping the liquid b into the liquid a, and controlling temperature to react for 1-5h so as to obtain a pre-polymerization product; and (4) successively carrying out termination, chain extension and neutralizing treatment to the obtained product to obtain an aqueous polyurethane product. The environmentally-friendly coating printing adhesive obtained with the preparation method disclosed by the invention has the advantages of good silk screen type crosslinking behavior, water resistance, yellowing resistance, stable and nontoxic emulsion and better electrolyte resistance, acid resistance and alkaline resistance. Printing fabric has the advantages of soft and moist hand feel and strong colour fastness and is environmentally friendly.
Description
Technical field:
The present invention relates to a kind of environment-protection coating printing adhesive, particularly a kind of preparation method of environment-protection coating printing adhesive.
Background technology:
Most of tackiness agents of domestic production at present are cross-linking monomer with the NMA, can produce formaldehyde in the use, and are harmful to human body and environment.Also there are shortcomings such as kind is few, cost is high, stability of emulsion is poor, PRINTED FABRIC Boardy Feeling, fastness difference in the acrylate printing adhesive of domestic production.Progressively improve the continuous enhancing with people's environmental consciousness along with environmental regulation; High-performance, printing and dyeing coating variety nuisanceless, that economize the energy more and more receive people's attention; Water-borne coatings has obtained using widely in cotton, fiber crops, silk, hair and synthetic printing; Compare with traditional dye printing technology, pigment printing has advantages such as technical process is short, energy consumption is low, pollution-free basically.The quality of pigment printing effect depends on the quality of binder performance to a great extent.The aqueous polyurethane coating printing adhesive is a kind of novel environment-friendly tackiness agent, have do not fire, advantage such as nontoxic, non-environmental-pollution, no disaster hidden-trouble, thereby more and more receive people's attention.Polyisocynate monomer commonly used mainly contains 2; 4-dimethyl-vulcabond (TDI), 4,4 '-'-diphenylmethane diisocyanate (MDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI) etc. are owing to TDI, MDI contain the rigidity aromatic ring; Make that the force of cohesion of urethane 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 urethane bigger owing to contain alicyclic ring, has excellent yellowing resistance, and weathering resistance is nontoxic.And HDI does not contain ring texture, and intensity is less, but its texture ratio 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 environment-protection coating printing adhesive 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 environment-protection coating printing adhesive; May further comprise the steps: (1) adds the dibutyl tin laurate of organic solvent N-Methyl pyrrolidone, IPDI and catalytic amount in being full of the reaction kettle of rare gas element; Be heated to 70 ℃ of dissolvings, obtain a liquid; (2) with the polyoxyethylene glycol PEG-600 and the TriMethylolPropane(TMP) TMP of metering, be dissolved in an amount of N-Methyl pyrrolidone, obtain b liquid; (3) b liquid slowly is added drop-wise in a liquid,, obtains prepolymer product in 90 ~ 105 ℃ of temperature control reaction 1 ~ 5h; (4) in the prepolymer product that step (3) is obtained, add by 1,4-butyleneglycol and dimethylol propionic acid are according to the composite compound end-capping reagent of the mass ratio of 7-8:1, insulation reaction 1 ~ 5h; (5) add the chainextender Diisopropylamine, carry out chain extending reaction, (6) add neutralizing agent aqueous sodium carbonate and skimmer, regulate pH=6 ~ 8, promptly get product.
The mass ratio of said PEG-600 and TMP is 1 ~ 15:1.
Compared with prior art, the present invention has the following advantages: environment-protection coating printing adhesive that the present invention obtains, have good mesh-like bridging property, and emulsion-stabilizing is nontoxic, has electrolyte-resistant and acid-proof alkaline preferably; The PRINTED FABRIC feel is soft, moist, and colour fastness is strong, environmental friendliness.
Embodiment:
Below in conjunction with embodiment the present invention is done detailed description further, but the scope that the present invention requires to protect is not limited to the scope that embodiment representes.
Embodiment 1:
In the reaction kettle that is full of nitrogen or rare gas element, add organic solvent N-Methyl pyrrolidone (100.0kg) and IPDI (300.0kg) successively, two LAURIC ACID 99 MIN diisobutyl tin (1.25kg) of catalytic amount are heated to 70 ℃ of dissolvings under stirring; In reaction kettle, slowly drip the mixing solutions of PEG-600 (200.0kg) and TMP (50.0kg) and N-Methyl pyrrolidone (50.0kg), controlled temperature drips and finishes insulation reaction 1 ~ 5h at 90 ~ 105 ℃; Add end-capping reagent 1,4-butyleneglycol (108.0kg), dimethylol propionic acid (14.0kg); Reaction 1 ~ 5h then adds Diisopropylamine (65.0kg) in reaction solution, carry out chain extending reaction; Reaction solution is cooled to 80 ℃, adds aqueous sodium carbonate (1550kg) neutralizing agent, skimmer; Reaction 1h makes PH=6.9, promptly obtains the aqueous polyurethane product.
