Abstract
The invention relates to a waterproof breathable organic silicon synthetic leather and a manufacturing method thereof. The synthetic leather comprises a cloth substrate or a fiber substrate and at least one organic silicon rubber layer compounded on the surface thereof, wherein the organic silicon rubber is prepared from 50-70% of vinyl-containing polydiorgnosiloxane base polymer, 2-5% of silicon-hydrogen bond-containing oligomeric siloxane vulcanization crosslinking agent, 0.5-2% of platinum compound vulcanization catalyst, 0.5-2% of alkynol hydrosilylation addition reaction inhibitor, 5-10% of white carbon black, 5-10% of calcium carbonate and 10-20% of sodium chloride of 100-200 meshes. The manufacturing method of the synthetic leather comprises the following steps: selecting a substrate; gluing; drying and curing; and boiling to leach the sodium chloride. Since the sodium chloride is added and the synthetic leather is boiled in water after being molded, the sodium chloride can be completely dissolved in the water, so that a certain number of air holes can be formed in the synthetic leather, thereby enduing the synthetic leather with certain breathability. Because the formed air holes have small hole diameters, water can not penetrate through the air holes of the synthetic leather, thereby ensuring the favorable waterproof function.
Description
Technical field
The invention belongs to the technical field of synthetic leather, particularly a kind of waterproof and breathable organosilicon synthetic leather and manufacture method thereof.
Background technology
Chinese patent application number is ventilating organosilicon synthetic leather of 200510034344.5 and preparation method thereof, discloses a kind of ventilating organosilicon synthetic leather, and it can be applicable to fields such as dress ornament, footwear, furniture, incrustation, packing.Be to constitute by cloth base material or fiber base material and organic silicon rubber, compound at least one deck organic silicon rubber on the surface of cloth base material or fiber base material, the outer surface of organic silicon rubber can suitably apply the organosilicon coatings of polychrome.Procedure of processing has selected base material, gluing, baking and curing etc., and processing technology is simple, and cost of manufacture is low, and is pollution-free, and solidification effect is good.The synthetic leather of producing has certain gas permeability, but the waterproof and breathable performance of above-mentioned synthetic leather still can not reach effect preferably.
Summary of the invention
The present invention provides a kind of organosilicon synthetic leather with advantages of good waterproof property in order to overcome the deficiency of above technical elements.
The present invention realizes in the following manner.
A kind of waterproof and breathable organosilicon synthetic leather is characterized in that being made of cloth base material or fiber base material and organic silicon rubber, compound at least one deck organic silicon rubber on the surface of cloth base material or fiber base material, and described organic silicon rubber is mixed and made into by following component:
The poly-diorganosiloxane base polymer 50-70% that contains vinyl,
The oligosiloxane vulcanization crosslinking agent 2-5% that contains si-h bond,
Platinum compounds sulphurized catalyst 0.5-2%,
Alkynol hydrogen silication addition reaction inhibitor 0.5-2%,
White carbon 5-10%,
Calcium carbonate 5-10%,
100-200 purpose sodium chloride 10-20%;
Described waterproof and breathable organosilicon synthetic leather adopts following steps to make:
(1) selected base material, base material be dip-coating or spraying silane finish suitably, strengthens the adhesive force of base material and plane materiel;
(2) gluing;
(3) baking and curing, the base material that is compounded with liquid silastic enters the drying tunnel baking and curing, and temperature is 80-150 ℃ in the drying tunnel;
(4) in 50-60 ℃ of water boiling 10-24 hour, change water 2-5 time, sodium chloride is leached fully.
Beneficial effect: 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 synthetic leather has 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.
The specific embodiment:
Embodiment 1
A kind of waterproof and breathable organosilicon synthetic leather is made of nonwoven eedle-punched non-wovens and organic silicon rubber, compound one deck organic silicon rubber on the surface of nonwoven eedle-punched non-wovens, and organic silicon rubber is mixed and made into by following component:
The poly-diorganosiloxane base polymer 58% that contains vinyl,
Contain the oligosiloxane vulcanization crosslinking agent 5% of si-h bond,
Platinum compounds sulphurized catalyst 1.5%,
Alkynol hydrogen silication addition reaction inhibitor 1%,
White carbon 10%,
Calcium carbonate 8.5%,
100-200 purpose sodium chloride 16%.
The waterproof and breathable organosilicon synthetic leather adopts following steps to make:
(1) selected base material, base material be dip-coating or spraying silane finish suitably, strengthens the adhesive force of base material and plane materiel;
(2) gluing, gluing realize that in conjunction with an inguinal canal liquid silicone rubber is stored in the glue groove, by applying mechanism organic silicon rubber are compound on the base material, and roller covers, smooth;
(3) baking and curing, the base material that is compounded with liquid silastic enters the drying tunnel baking and curing, and temperature is 80 ℃ in the drying tunnel,
(4) boiling 10 hours in 60 ℃ of water is changed water 3 times, and sodium chloride is leached fully.
Permeability and water resistance test
Be that the prescription of 200510034344 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 900 gram/square metre skies, and synthetic leather rate of perviousness of the present invention is 3300 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 0.22% in the water sucting plate weight at control group synthetic leather rear, pad has increased by 0.24% 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 200510034344 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 200510034344 invention provides than the patent No., and combination property is better.
