At present, synthetic leather on the market, in the situation that running into violence use, as while making footwear, ball moving, be easy to occur damaged or fracture, the synthetic leather now also having, some high-intensity fabrics in centre, have been added, although can play the effect of gaining in strength, at thickening synthetic leather and when adding new fabric, can affect to the original permeability of synthetic leather.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of high strength synthetic leather, is carrying the high-intensity while, guarantees original gas permeability.
For achieving the above object, the utility model provides following technical scheme: a kind of high strength synthetic leather, comprise the base cloth being formed by nonwoven cloth material, and be arranged on adhesive layer, the microvoid polyurethane top layer on base cloth, between described base cloth and microvoid polyurethane top layer, be equipped with some monofilament glass fibres, described each monofilament glass fibre is all embedded in adhesive layer;
Described adhesive layer consists of silastic material, offers ventilative through hole on the top layer of described adhesive layer.
By adopting technique scheme, between described base cloth and microvoid polyurethane top layer, be equipped with some monofilament glass fibres, can utilize large, the soft characteristic of described monofilament glass fiber strength, improve synthetic leather intensity, do not lose again pliability, the more important thing is, carrying the high-intensity while, on the top layer of adhesive layer, offer ventilative through hole, guaranteed the due gas permeability of synthetic leather.
The utility model is further set to: between described microvoid polyurethane top layer and adhesive layer, be provided with microcellular rubber layer, the one side of the relative adhesive layer of described microcellular rubber layer is provided with some hemispherical protuberances.
By adopting technique scheme, microcellular rubber layer is set between described microvoid polyurethane top layer and adhesive layer, guaranteeing under the prerequisite of synthetic leather gas permeability, utilize microcellular rubber layer to wrap up monofilament glass fibre, solve monofilament glass fibre and be difficult to fixing problem, also made synthetic leather there is the performances such as light weight, wear-resisting, adiabatic, sound insulation, electric insulation, and had buffering and filtration, intensity is higher, more durable in use; The setting of hemispherical protuberances, can be in synthetic leather pressurized, utilize projection to absorb, slow down and be under pressure, and when recovering, utilize the fast quick-recovery deformation of protruding elasticity, and projection can also strengthen microcellular rubber layer and the bonding intensity of adhesive layer.
The utility model is further set to: the diameter of described monofilament glass fibre is 2 to 8 microns.
By adopting technique scheme, because glass fibre is pumped into after silk, its intensity greatly increases and has a flexibility, can become good structure material after coordinating resin to give its shape, glass fibre with its diameter, diminish and intensity increase, therefore, the diameter of described silk glass fibre is made to 2 to 8 microns, considered production difficulty and cost, guaranteeing under the prerequisite of economic benefit, the beneficial effect of monofilament glass fibre is maximized, reach suitable strength.
The utility model is further set to: the length of described each monofilament glass fibre is 40 to 60 millimeters.
By adopting technique scheme, the length of described each monofilament glass fibre is made to 40 to 60 millimeters, on the one hand, this length convenient-laying, on the other hand, also guaranteed in the synthetic leather of each monofilament glass fibre after making finished product, can be not too short because of length, cannot reach performances such as strengthening stability, intensity and antifatigue.
The utility model is further set to: the one side on the relative microvoid polyurethane of described microcellular rubber layer top layer is staggeredly equipped with the lines of strip.
By adopting technique scheme, can utilize the lines of described strip, strengthen the friction between described microcellular rubber layer and polyurethane skin layer, thereby improve the bonding fastness of this two layers of material, in addition, the lines of strip also can utilize the jut of lines, improves the impact resistance of described synthetic leather.

The specific embodiment
Referring to figs. 1 through Fig. 2, the utility model high strength synthetic leather embodiment is described further.
As shown in Figure 1 to Figure 2, a kind of high strength synthetic leather, comprise the base cloth 1 being formed by nonwoven cloth material, and be arranged on adhesive layer 2, the microvoid polyurethane top layer 3 on base cloth 1, between described base cloth 1 and microvoid polyurethane top layer 3, be equipped with some monofilament glass fibres 4, described each monofilament glass fibre 4 is all embedded in adhesive layer 2;
Described adhesive layer 2 consists of silastic material, offers ventilative through hole on the top layer of described adhesive layer 2.
Between described base cloth 1 and microvoid polyurethane top layer 3, be equipped with some monofilament glass fibres 4, can utilize large, the soft characteristic of described monofilament glass fibre semi-finals degree, improve synthetic leather intensity, do not lose again pliability, the more important thing is, carry the high-intensity while, on the top layer of adhesive layer 2, offering ventilative through hole, guaranteeing the due gas permeability of synthetic leather.
Between described microvoid polyurethane top layer 3 and adhesive layer 2, be provided with microcellular rubber layer 5, the one side of described microcellular rubber layer 5 relative adhesive layer 2 is provided with some hemispherical protuberances 6.
Between described microvoid polyurethane top layer 3 and adhesive layer 2, microcellular rubber layer 5 is set, guaranteeing under the prerequisite of synthetic leather gas permeability, utilize microcellular rubber layer 5 to wrap up monofilament glass fibre 4, solve monofilament glass fibre 4 and be difficult to fixing problem, also make synthetic leather there is the performances such as light weight, wear-resisting, adiabatic, sound insulation, electric insulation, and having buffering and filtration, intensity is higher, more durable in use; The setting of hemispherical protuberances 6, can be in synthetic leather pressurized, utilize projection 6 to absorb, slow down and be under pressure, and when recovering, utilize the fast quick-recovery deformation of elasticity of projection 6, and projection 6 can also strengthen microcellular rubber layer 5 intensity bonding with adhesive layer 2.
