Abstract
The invention discloses a degradable porous film for wind prevention, ventilation and bacteriostasis, which is prepared by the steps of: adjusting the liquid temperature of a reactor to 30 DEG C, and uniformly mixing butanone, dimethylformamide, toluene and polyurethane resin at the first stirring rate according to the mass ratio of 10:10:25:100 to form a first primary resin solution; slowly adding 1, 6-diisocyanate hexane into the first primary resin solution to form a first primary resin mixed solution; mixing the solvent which is formed by water and the butanone with the first primary resin solution to form the first primary resin mixed solution; mixing the regulated resin mixed solution with N-methylethanolamine; filtering the regulated first primary resin mixed solution by a nylon net of 100-200 meshes, so the filtered first primary resin mixed solution is obtained; and drying the macromolecular mixed resin which is scraped on the silicon oil release paper in a tensioning state by four stages. The porous film has uniform and dense micropores at a nanoscale of 50-200nm, has good wind prevention, moisture permeation, waterproofness, ventilation and excellent bacteriostasis, and is contributed to maintaining the long-term dryness of the film surface and wearing health when being used.
Description
Technical field
The present invention relates to a kind of windproof vapour bacteriostatic degradable apertured film that is used for, belong to the weaving face fabric technical field.
Background technology
Existing polyurethane film is that the multipolymer by one-component constitutes, and is alternately arranged along macromolecular chain by hard segment and soft chain segment.Hard segment is hydrophobic, and it can stop water droplet to pass through, and plays waterproof action; Soft chain segment is hydrophilic, it can with the water molecules effect, by hydrogen bond and other Intermolecular Forces,, be delivered to low humidity one side desorb, thereby reach the effect that wets through hydrophilic group on the macromolecular chain at high humidity one side absorbent moisture.Passing through wet process is " absorption-diffusion-desorb ".Its shortcoming is this kind nonporous moisture permeable film, and moisture permeable amount is very much limitedly can reach 5000g/m by ASTM E96BW
2/ D is difficult to satisfy people's rapid sweat vapour discharging needs that produce when vigorous exercise, is prone to let the wearer produce very heavy wet vexed sense.

Step 1-3, keep 30 ℃ of liquid temperature, water and butanone are mixed the formation solvent according to 9: 1 mass ratio, this solvent and the said first main mixed resin solution mix the first main mixed resin solution after the formation adjusting according to 30: 100 mass ratios;
Step 1-4, keep 30 ℃ of liquid temperature, mixed resin solution and the ratio of N-Mono Methyl Ethanol Amine by 100: 1 with step 1-3 regulates slowly drop into (CL-15 can pass through the main ingredient expression better)
Step 1-5, the first main mixed resin solution after the first main mixed resin solution after the said adjusting filtered through 100～200 purpose nylon net filters;
Step 1-6, the first main mixed resin solution standing and defoaming after the said filtration is handled;
Step 1-7, the thickness that said polymer hybrid resin is pressed 0.005-0.05mm apply and the centrifugal paper of silicone oil top layer;
Step 1-8, said blade coating had under the tension state in the polymer hybrid resin of silicone oil separate-type paper drying, drying time is 2-3 minute, and divides the four-stage fs: under 60 ℃ condition, and under swiftly flowing air atmosphere, carry out; Subordinate phase: under 90 ℃ condition, and under low speed mobile air atmosphere, carry out; Phase III: under 120 ℃ condition, and under swiftly flowing air atmosphere, carry out; Stage: under 140 ℃ condition, and under swiftly flowing air atmosphere, carry out;
Step 1-9, with said through the oven dry film carry out the refrigerated separation bundling;
Further improved technical scheme is following in the technique scheme:
Utilized the different boiling of different solvents butanone, N, toluene and water can do stage volatilization system as preferred step 1-1 and 1-3.
Accelerate stirring velocity as the said stirring velocity of optimized technical scheme with the addition of solvent, and keep at the uniform velocity more than 5 minutes of the highest 2000 commentaries on classics;
Be 2 hours as the standing and defoaming treatment time among the preferred said step 1-6;
As the centrifugal paper film of the silicone oil stripping technique described in preferred said step 1-7,1-8 and the 1-9;
Because the technique scheme utilization, the present invention compared with prior art has advantage and effect:
