Problems solved by technology

[0003] (1) The pores of the primer layer formed by the primer slurry are easy to overlap, and the water pressure is relatively low, so it is difficult to break through 3500MMH2O;
[0004] (2) The surface toughness of the microporous coating film formed by the existing primer slurry is not enough, not scratch-resistant, and not resistant to film;
[0005] (3) The grade A rate of the finished product of the microporous coating formed by the existing primer slurry is low, and the failure rate reaches more than 30%

Embodiment

[0021] Embodiment: A kind of manufacturing process of wear-resistant primer material for breathable fabrics, comprising:

[0022] Step 1. Mix methyl ethyl ketone, water and polyurethane resin according to the mass ratio of 66~68:3~5:29~31 to form the main resin solution. Note: the mixing ratio of Example 1 is 66:3:31, Example 2 The mixing ratio is 67:5:29, and the mixing ratio of Example 3 is 68:4:30;

[0023] Step 2, adding N-methylethanolamine as an accelerator in the main resin solution of step 1, the mass ratio of the main resin solution and the accelerator is 100:2.5 or 3 or 3.5;

[0024] Step 3: Slowly put the mixture of methyl ethyl ketone and toluene into the main resin solution in step 2 and stir evenly to form a main resin mixed solution. The mass ratio of this mixed solution to the main resin solution is 100:43 or 44 or 45, so Butanone and toluene form the mixed solution according to the mass ratio of 1:2 or 1:1;

[0025] Step 4. Stir the mixed solution of hexahex...

Abstract

The invention discloses a manufacturing technology for a wear-resisting prime coat material for a breathable fabric. The technology comprises the following steps: uniformly mixing butanone, water and polyurethane resin at the mass ratio of (66-68):(3-5):(29-31) to form a main resin solution; adding N-methyl ethanolamine as an accelerant into the main resin solution, wherein the mass ratio of the main resin solution to the accelerant is 100:(2.5-3.5); uniformly mixing water and butanone at the mass ratio of 9:1 to obtain a solvent, wherein the mass ratio of the solvent to a mixed main resin solution adjusted in step 4 is 100:(30-35); and standing a filtered mixed main resin solution for at least 2 hours, and performing defoaming treatment. According to the technology, the probability that the surface part, contacted with air, of liquid resin crusts easily and is turned from a liquid state into a solid state to become a dead colloid is avoided effectively, and the phenomenon that a great amount of adhesive tape abnormity is caused during the operation process to reduce the level of the fabric is avoided.

Description

technical field [0001] The invention relates to a manufacturing process of a wear-resistant primer material for breathable fabrics, belonging to the technical field of textile fabrics. Background technique [0002] The hydrophilic non-porous PU moisture-permeable raw material currently used in the market, this method is to apply the hydrophilic non-porous PU moisture-permeable raw material to the surface of the base fabric through a coating machine, and then pass it through the coating machine oven. Hot air drying, solvent volatilization, and film formation. Make the fabric waterproof and moisture-permeable. The moisture-permeable principle is that the moisture-permeable raw materials contain hydrophilic substances, which have the functions of moisture absorption-diffusion-desorption. The moisture-permeable fabric processed by this process will swell when it encounters water, resulting in a decrease in the abrasion resistance of the film, and the moisture-permeable performa...
