Abstract
The invention discloses a preparation process of a first coat material with the moisture permeable function. The process comprises the following steps: uniformly mixing butanone, water and polyurethane resin in mass ratio of (66-68) to (3-5) to (29-31) to obtain a main resin solution; agitating and uniformly mixing 1,6-diisocyanatohexane and the main resin mixed solution obtained in step 3 in mass ratio of 100 to (1.5-2.5) at the rotating speed of 1000rpm and under the temperature of 25 to 35 DEG C to obtain the regulated main resin mixed solution; filtering the regulated main resin mixing solution through a nylon mesh with 100 to 200 meshes to obtain the filtered main resin mixed solution; standing the filtered main resin mixing solution for at least 2 hours and defoaming, wherein the standing is performed in a vacuum condition for 2 hours. According to the preparation process, the weakness that the first coat material is easily expanded in water is overcome, the moisture permeable performance of a fabric body can be improved, so that the fabric is high in service performance, and the wear resistance is greatly improved.

(1) primary coat slurry formation priming coat hole is easily overlapping, and hydraulic pressure is more on the low side, is difficult to break through 3500MMH2O;
(2) existing primary coat slurry forms the toughness of priming coat micro porous coating epithelial surfaces not, not scratch resistance, not resistance to film;
(3) the finished product A level rate of existing primary coat slurry formation priming coat micro porous coating is on the low side, and miss ratio reaches more than 30%.
Summary of the invention
The object of the invention is to provide a kind of basecoat material preparation technology with moisture-inhibiting function, adopts the coating fabric micropore of this basecoat material preparation technology even, meets water and is not easy to expand, thus have the raising of the water vapour permeability helped in fabric itself.
For achieving the above object, the technical solution used in the present invention is: a kind of basecoat material preparation technology with moisture-inhibiting function, is characterized in that: comprising:
Step one, by butanone, water and polyurethane resin according to the mass ratio of 66 ~ 68:3 ~ 5:29 ~ 31 mix formed main resin solution;
Step 2, in the main resin solution of step one, add N-methylethanolamine as promoter, the mass ratio of this main resin solution and promoter is 100:2.5 ~ 3.5;
Step 3, the mixed liquor of butanone and toluene to be dropped into lentamente in the main resin solution of step 2 and uniform stirring forms main mixed resin solution, mass ratio 100:43 ~ 45 of this mixed liquor and main resin solution, described butanone and toluene form described mixed liquor according to the mass ratio of 1:2 or 1:1;
Step 4, the main mixed resin solution of 1,6-diisocyanato-Hexane and step 3 to be stirred the main mixed resin solution after being mixed to form adjustment with 1000rpm rotating speed in 25-35 DEG C of temperature according to the mass ratio of 100:1.5 ~ 2.5;
Step 5, water and butanone are mixed formation solvent according to the mass ratio of 9:1, main mixed resin solution mass ratio after this solvent and step 4 regulate is 100:30 ~ 35, then this solvent is dropped into the main mixed resin solution Homogeneous phase mixing after described adjustment with at least six times;
Step 6, by the main mixed resin solution after the adjustment of step 5 by 100 ~ 200 object nylon net filters obtain filter after main mixed resin solution;
Step 7, by the main mixed resin solution after the filtration of step 6 leave standstill within least 2 hours, carry out deaeration process; Described step 7 leaves standstill and leaves standstill under vacuum, and the time is 2 hours.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
Meet the water capacity expansive weakness when 1, the invention solves original slurry processing coating fabric, and improve the water vapour permeability of fabric itself, make fabric have higher service, ABRASION RESISTANCE is improved greatly.
2, its solvent of manufacturing technique of the present invention, have employed the combination of the mixed solvent of water and butanone and takes specific ratio, thus can ensure to form uniform micropore in following process, does not exist residual.
3, the present invention modulates particular viscosity slurry, ensure that the mobility of resin is better, and permeability is comparatively appropriate, good with the then fastness of fabric panel; Effectively prevent resin liquid surface and the easy skinning of air contact portion, have fluid state to be converted into solid-state, thus become the probability of dead colloid, and it is abnormal to avoid in operation process, to produce a large amount of adhesive tape, causes fabric to demote.
4, water of the present invention and butanone drop into several times in batches, and (1) is avoided producing polyurethane and assembled, and cannot ensure that polyurethane and solvent components can mix, and can ensure that the activity time of polyurethane is long; (2) adding while stirring, when adding after solvent body fully mixes with polyurethane, avoiding the formation difficulty producing granule and polyurethane epithelium, prevent hydraulic pressure on the low side and affect uniformity in local; Secondly, take deaeration to form even spread, ensure that the uniformity of hydraulic pressure and moisture-inhibiting.
