Technical field:
The present invention relates to technical field of synthetic leather, refer in particular to a kind of ventilating organosilicon synthetic leather, it can be applicable to fields such as dress ornament, footwear, furniture, incrustation, packing.
Background technology:
At present, the synthetic leather that the market occurs is many to be made by base material and PVC or PU material, because PVC material and PU properties of materials have harmful gas in the anabolic process generation, influences healthyly, and the feature of environmental protection is poor; And the gas permeability of PVC material and PU material is not good, and the synthetic leather of making is airtight, and when being used for product such as clothes, shoes, face shield, sofa, chair, the gas permeability shortcoming is brought uncomfortable sensation to the user, even injury user skin.
Summary of the invention:
The object of the invention is to overcome the defective of prior art, and a kind of good permeability is provided, nontoxic organosilicon synthetic leather.
Another purpose of the present invention provides a kind of simple to operate, the preparation method of the organosilicon synthetic leather of being convenient to process.
For achieving the above object, the present invention constitutes compound at least one deck organic silicon rubber on the surface of cloth base material or fiber base material by cloth base material or fiber base material and organic silicon rubber; And also apply the organosilicon coatings of polychrome suitably at the outer surface of organic silicon rubber.
Organic silicon rubber is an add-on type liquid silicon rubber, its key component comprises the poly-diorganosiloxane base polymer that contains vinyl, contain the oligosiloxane vulcanization crosslinking agent of si-h bond, platinum compounds sulphurized catalyst, alkynol hydrogen silicon sulfuration addition reaction inhibitor and filler; Wherein proportioning is as follows:
The poly-diorganosiloxane base polymer 30～95% that contains vinyl
Contain the oligosiloxane vulcanization crosslinking agent 1～10% of si-h bond
Platinum compounds sulphurized catalyst 0.001～5%
Alkynol hydrogen silicon sulfuration addition reaction inhibitor 0.01～5%
Filler 0～50%.
The making of ventilating organosilicon synthetic leather mainly comprises the steps:
1), selected base material, base material is dip-coating or spraying silane finish suitably, the adhesive force of enhancing base material and plane materiel;
2), gluing, last glue process are realized in conjunction with a glue groove, liquid silicone rubber is stored in the glue groove and by applying mechanism organic silicon rubber is compound on the base material, applying mechanism adopts the coating wheel to combine formation with roller, apply wheel and be stained with and be covered with machine silicon rubber on base material, roller covers, smooth;
3), baking and curing, the base material that is compounded with liquid silastic enters the drying tunnel baking and curing, the temperature in the drying tunnel is 80～200 ℃.
The technique effect that the present invention reaches is as follows:
1, adopt organic silicon rubber material to make synthetic leather, overcome the deficiency of PVC or PU synthetic leather, especially strengthen the gas permeability of synthetic leather, nontoxic, harmless.
2, break through the general layout of existing PVC or PU synthetic leather, increase the varietal character and the diversity of synthetic leather, improve the applicable surface of synthetic leather.
3, processing technology is simple, and cost of manufacture is low, and is pollution-free, and solidification effect is good.
Description of drawings:
Accompanying drawing 1 is a combination schematic diagram of the present invention;
Accompanying drawing 2 is a manufacture craft schematic diagram of the present invention.
The specific embodiment:
The present invention is described further below in conjunction with accompanying drawing:
Shown in the accompanying drawing 1, the present invention mainly is compound at least one deck organic silicon rubber 20 on the surface of cloth base material or fiber base material 10, cloth base material or fiber base material 10 are handled by silane finish, increase the composite force between organic silicon rubber 20 and cloth base material or the fiber base material 10, also apply the organosilicon coatings 30 of polychrome at the outer surface of organic silicon rubber 20, increase synthetic leather surface pleochroism, improve gloss.
In the present embodiment, organic silicon rubber 20 is an add-on type liquid silicon rubber, and its key component comprises the poly-diorganosiloxane base polymer that contains vinyl, contains the oligosiloxane vulcanization crosslinking agent of si-h bond, the platinum compounds sulphurized catalyst, alkynol hydrogen silicon sulfuration addition reaction inhibitor and filler; Wherein proportioning is as follows:
The poly-diorganosiloxane base polymer 30～95% that contains vinyl
Contain the oligosiloxane vulcanization crosslinking agent 1～10% of si-h bond
Platinum compounds sulphurized catalyst 0.001～5%
Alkynol hydrogen silicon sulfuration addition reaction inhibitor 0.01～5%
Filler 0～50%.
For example: get the poly-diorganosiloxane base polymer 65% that contains vinyl, contain the oligosiloxane vulcanization crosslinking agent 5% of si-h bond, platinum compounds sulphurized catalyst 0.2%, alkynol hydrogen silicon sulfuration addition reaction inhibitor 0.1% and filler 29.7% mix, and take place to form liquid silastic after the addition reaction.Wherein filler can adopt white carbon, MQ resin, silicon powder, calcium carbonate, diatomite or talcum powder, plays the effect of strengthening intensity.Certainly, can according to circumstances not need yet filled.
Certainly, the present invention also can adopt the condensed type liquid silastic, with terminal hydroxy group polydiorganosiloxanepolyurea or end alkoxyl dimethyl silicone polymer is basic compound, with multifunctional silane or siloxanes is cure-crosslinking agent, in the presence of catalyst, contact or the mixing of two components with moisture in the air, under room temperature cross-linking and curing reaction can take place, form elastomer.
The making of ventilating organosilicon synthetic leather mainly comprises the steps:
1), selected cloth base material or fiber base material, and base material 10 carried out suitably dip-coating or spraying silane finish, strengthen the adhesive force of base material;
2), gluing, last glue process realizes that in conjunction with a glue groove liquid silicone rubber is stored in the glue groove and by applying mechanism organic silicon rubber is compound on the base material, applies mechanism and adopts the coating wheel to combine formation with roller, apply wheel and be stained with and be covered with machine silicon rubber on base material, roller covers, smooth;
3), baking and curing, the base material that is compounded with liquid silastic is sent into the drying tunnel baking and curing, the temperature in the drying tunnel is 80～200 ℃.
