Description
Technical field
The present invention relates to a kind of preparation method of composite gum, be specifically related to a kind of preparation method of aqueous polyurethane composite gel.
Background technology
Laminated film is often sticked with glue by two or more performance different film that agent is bonding to form, the tackiness agent that uses is mainly solvent type polyurethane adhesive at present, by main body, solidifying agent and solvent composition, and at the following curing molding just more than 30 hours of 50～60 ℃ of heating, making processes is consuming time oversize, and the easy contaminate environment of compound tense solvent evaporates, harmful HUMAN HEALTH causes the wasting of resources simultaneously.Existing water-base cement water to replace organic solvent has reduced the pollution of environment, can not be used for re-compounded problem but also exist, and makes productive rate reduce, and has caused the waste of resource.
Summary of the invention
Be to solve above-mentioned prior art problems order of the present invention, a kind of transparency height be provided, not xanthochromia, do not after-tack, water-fast, weather-proof, snappiness is good, the preparation method of the aqueous polyurethane composite gel that the short period of time can curing molding at normal temperatures.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of aqueous polyurethane composite gel is polymerized by polymeric polyisocyanate and polyalcohols, and its key technical indexes is:
Appearance milky white band blue light
Solid masses content is once-combined 29～31%, secondary compound 42～44%
Viscosity mpa.s＜50
PH value 5～7
Wet glue quantity≤4.5
Described polyalcohols is polyoxypropyleneglycol (PPG), and described polymeric polyisocyanate is a Toluene-2,4-diisocyanate, 4-vulcabond (TDI).
A kind of method for preparing above-mentioned aqueous polyurethane composite gel may further comprise the steps:
A. be that 90～110 parts polyalcohols, 90～110 parts polymeric polyisocyanate and 25～35 parts two hydrocarbon methylpropanoic acids add in the reaction chamber with mass parts, under the nitrogen protection, stirring at normal temperature;
B. above-mentioned product is warming up to 80 ℃, drips the stannous octoate solution of 0.1～0.14 part of mass parts, after the reaction, drip properties-correcting agent and continue reaction;
C. final reacting product among the step b is cooled to 40 ℃, adding assistant and mass parts are that 600～700 parts deionized water disperses, and are heated to 52 ℃, be evacuated to vacuum concentration filter product of the present invention.
Described polyalcohols is polyoxypropyleneglycol (PPG), and polymeric polyisocyanate is a Toluene-2,4-diisocyanate, and 4 vulcabond (TDI), properties-correcting agent are that mass parts is 40～50 parts a trolamine, and auxiliary agent is that mass parts is 25～35 parts a alizarin assistant.
Advantage of the present invention is:
1. the present invention is the medium replace organic solvent with water, every economic and technical norms are better than the solvent borne polyurethane film, nuisanceless, nothing waste, obviously reduce enterprise's production cost, problems such as inflammable and explosive potential safety hazard that solvent-borne type glue produces and environmental pollution have thoroughly been eliminated simultaneously, full-scope safeguards user health.
2. product transparency height of the present invention, not xanthochromia, do not after-tack, water-fast, weather-proof, snappiness is good, recombining process is the short period of time curing molding at normal temperatures, and it is compound to can be used for secondary.
3. product of the present invention can be applicable to the multiple film of food product pack such as salt, betel nut, has filled up domestic blank.
