Abstract
The invention discloses a manufacturing method for a top coating sizing agent with high moisture permeability. The manufacturing method comprises the following steps: 1, uniformly mixing butanone, water and polyurethane resin according to the quality proportion of 67: 5: 29 to form a main resin solution; 2, slowly putting the mixed liquor of the butanone and methylbenzene into the main resin solution obtained in the step 1, and then uniformly mixing the mixed liquor and the main resin solution to form a main resin mixed solution; 3, mixing N-methyl ethanolamine and the main resin mixed solution obtained in the step 2 to form an adjusted main resin mixed solution; 4, putting a solvent into the adjusted main resin mixed solution at least six times, and uniformly mixing the solvent and the adjusted main resin mixed solution; 5, filtering the main resin mixed solution through a nylon net with 100-200 meshes to obtain a filtered main resin mixed solution; 6, standing the filtered main resin mixed solution obtained in the step 5 to perform the defoaming treatment, so that the viscosity of the matched liquor of the top coating sizing agent is 5000 mpas at 25 DEG C. The top coating sizing agent obtained by the preparation technology disclosed by the invention avoids the generation of granules and the forming difficulty of a polyurethane film, and prevents the problem that the water pressure is locally lower to influence the uniformity.
Description
Technical field
The present invention relates to the manufacture method that a kind of high water vapour permeability face is coated with slurry, belong to technical field of textile fabric.
Background technology
Hydrophilic non-porous matter PU moisture-inhibiting raw material in the market, the method is hydrophilic non-porous matter PU moisture-inhibiting raw material, through coating machine coating, blade coating in scrim surfaces, through coating machine baking oven hot-air seasoning, solvent evaporates, film forming.Make fabric have the function of Waterproof Breathable, its moisture-inhibiting principle is containing hydroaropic substance in moisture-inhibiting raw material,---diffusion---desorption that has moisture absorption.The moisture-permeable shell fabric of this processes, meet water and produce Peng Run, cause epithelium ABRASION RESISTANCE to decline, and fabric moisture transmission performance is relatively weak, general moisture permeability index is 2500-3500G/M.24H (JIS 1099 A1).Adopting micro porous coating to solve the problems of the technologies described above although exist in prior art, there is following technical problem in existing micro porous coating:
(1) existing is coated with slurry forming surface coating uniformity and uniformity, and the chance water capacity easily expands;
(2) existing painting slurry forming surface coating hole is easily overlapping, and hydraulic pressure is more on the low side, is difficult to break through 3500MMH2O;
(3) existing the toughness being coated with slurry forming surface coating epithelial surfaces is inadequate, not scratch resistance, not resistance to film;
(4) the finished product A level rate of existing finishing coat is on the low side, and miss ratio reaches more than 30%.
Summary of the invention
The object of the invention is to provide the manufacture method that a kind of high water vapour permeability face is coated with slurry, and the coating fabric micropore that its face is coated with slurry formation is 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 high water vapour permeability face is coated with the manufacture method of slurry, comprising:
Step one, by butanone, water and polyurethane resin according to the mass ratio of 67:5:29 mix formed main resin solution;
Step 2, the mixed liquor of butanone and toluene to be dropped into lentamente in the main resin solution of step one 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 3, the main mixed resin solution of N-methylethanolamine and step 2 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 4, 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, this solvent is thought the main mixed resin solution Homogeneous phase mixing after dropping into described adjustment at least six times, the main mixed resin solution of described step 4 is modulated at 25 ~ 35 DEG C again;
Step 5, by the main mixed resin solution after the adjustment of step 4 by 100 ~ 200 object nylon net filters obtain filter after main mixed resin solution;
Step 6, to be left standstill by the main mixed resin solution after the filtration of step 5 and carry out deaeration process, described is coated with the fluid,matching viscosity 25 DEG C of slurry is 5000mpas.
The technical scheme improved further in technique scheme is as follows:
As preferably, described step 6 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.
