Description
Technical field
The invention belongs to the technical field of synthetic leather, particularly a kind of waterproof air previous polyurethane artificial leather.
Background technology
China Patent No. is the manufacture method of 98100908.5 polyurethane artificial leather, discloses a kind of Synthetic Leather, have mechanical performance preferably, but the permeability of above-mentioned synthetic leather does not reach effect preferably.If make clothes or shoes with the artificial leather of foregoing invention, the sweat volatilization is not come out, and causes very large discomfort to the user.
Summary of the invention
The present invention provides a kind of both had good flexural strength, hardness, ABRASION RESISTANCE and humidity resistance, the polyurethane artificial leather that has advantages of good waterproof property again in order to overcome the deficiency of above technical elements.
The present invention realizes in the following manner.
A kind of waterproof air previous polyurethane artificial leather, composed of the following components; Polyurethane particles 60-70wt%, lubricant 3-7wt%, blowing agent 1-3wt%, mediation resin 4-8wt%, calcium carbonate 10-15wt%, 100-200 purpose sodium chloride 10-15wt%, colorant 1-3wt%.
Described waterproof air previous polyurethane artificial leather is characterized in that described lubricant is a phthalic acid ester.
Described waterproof air previous polyurethane artificial leather is characterized in that described lubricant active constituent content is 4-6%.
Described waterproof air previous polyurethane artificial leather is characterized in that described blowing agent is azodiisobutyronitrile or azo dimethylformamide.
Described waterproof air previous polyurethane artificial leather is characterized in that described mediation resin is polyacrylate or polyisobutene acid esters.
A kind of preparation method of described waterproof air previous polyurethane artificial leather is characterized in that may further comprise the steps:
(1) material for preparing is dropped into mixer, mix;
(2) insert banbury, heat up and plasticate;
(3) insert two roller machines, further gel, homogenizing, send filter to filter to extrude, to remove impurity;
(4) deliver to calender, pull out into adhesive plaster;
(5) deliver to make-up machine, under heating and pressurizing, fit with base cloth, lining;
(6) deliver to foaming machine, blowing agent is at high temperature reduced foaming, in 50-60 ℃ water, carried out afterwards boiling 10-24 hour, change water 2-5 time;
(7) make product through embossing, post processing.
In the synthetic leather of the present invention, add a certain amount of sodium chloride, after the synthetic leather moulding,, sodium chloride is dissolved in the water fully, make synthetic leather produce certain pore, can guarantee that steam sees through, make synthetic leather have certain gas permeability through boiling in the water.Because the air vent aperture that produces is very little, water can not see through the pore of synthetic leather, therefore, has good water-proof function.
Beneficial effect: in the prescription of synthetic leather, add the sodium chloride component, and in preparation process, the sodium chloride dissolving is removed, make original very fine and close resin glue liquid layer produce a lot of very tiny holes, help the discharge of steam, strengthened the permeability of synthetic leather of the present invention, but can not cause very big influence water resistance.
The specific embodiment:
Embodiment 1
A kind of waterproof air previous polyurethane artificial leather, composed of the following components; Polyurethane particles 60wt%, phthalic acid ester 3wt%, azodiisobutyronitrile 1wt%, polyacrylate 8wt%, calcium carbonate 15wt%, 100 purpose sodium chloride 12wt%, colorant 1wt%.
The preparation method of waterproof air previous polyurethane artificial leather may further comprise the steps:
(1) material for preparing is dropped into mixer, mix;
(2) insert banbury, heat up and plasticate;
(3) insert two roller machines, further gel, homogenizing, send filter to filter to extrude, to remove impurity;
(4) deliver to calender, pull out into adhesive plaster;
(5) deliver to make-up machine, under heating and pressurizing, fit with base cloth, lining;
(6) deliver to foaming machine, azodiisobutyronitrile is at high temperature reduced foaming, then, in 50 ℃ of water, carried out boiling 24 hours, change water 5 times, sodium chloride is leached fully;
(7) make product through embossing, post processing.
Embodiment 2
A kind of waterproof air previous polyurethane artificial leather is characterized in that composed of the following components; Polyurethane particles 67wt%, phthalic acid ester 4wt%, azo dimethylformamide 3wt%, polyisobutene acid esters 4wt%, calcium carbonate 10wt%, 200 purpose sodium chloride 10wt%, colorant 2wt%.
The preparation method of waterproof air previous polyurethane artificial leather may further comprise the steps:
(1) material for preparing is dropped into mixer, mix;
(2) insert banbury, heat up and plasticate;
(3) insert two roller machines, further gel, homogenizing, send filter to filter to extrude, to remove impurity;
(4) deliver to calender, pull out into adhesive plaster;
(5) deliver to make-up machine, under heating and pressurizing, fit with base cloth, lining;

Permeability and water resistance test
Be that the prescription of 98100908.5 disclosure of the Invention and method are prepared into synthetic leather and organize in contrast according to China Patent No., carry out the contrast test of water proofing property and gas permeability with the waterproof and breathable synthetic leather of making according to prescription provided by the present invention and method and test.
The permeability test
Permeability characterizes by rate of perviousness.Get the beaker of two same capabilities, fill with the water of same amount respectively, two kinds of synthetic leather are covered respectively on the rim of a cup also fix, the water in the cup can only be volatilized, respectively the weight and the record of weighing two covering devices by the synthetic leather at rim of a cup place.At relative humidity of atomsphere 50%, under the condition that temperature is 21 ℃, measure every day by covering the steam vapour amount of the synthetic leather on the cup, i.e. rate of perviousness.Recording the control group rate of perviousness is 190 gram/square metre skies, and synthetic leather rate of perviousness of the present invention is 2900 gram/square metre skies.As seen, synthetic leather provided by the invention is accounting for very big advantage than the synthetic leather of control group aspect the permeability.
The water resistance test
Use rain drop test to come the testing water-proof performance.Prepare two water sucting plates with identical table area, equal volume and weight, fill up respectively at control group synthetic leather and synthetic leather of the present invention rear, current with uniform pressure spray test specimens continuously at distance sample 30cm place, continue to spray 3 hours weight of two water sucting plates of weighing then.Find after the weighing, pad has increased by 0.18% in the water sucting plate weight at control group synthetic leather rear, pad has increased by 0.20% in the water sucting plate weight at synthetic leather of the present invention rear, as seen, synthetic leather of the present invention is that the synthetic leather of 98100908.5 disclosure of the Invention just has reduction slightly than the patent No. aspect water resistance, but can not influence the water proofing property of not making after the finished product.
Synthetic leather of the present invention is better for the synthetic leather permeability that 98100908.5 invention provides than the patent No., and combination property is better.
