Abstract

The utility model discloses a composite material. The composite material comprises a middle layer made of a neoprene material, wherein a PU (polyurethane) synthetic leather layer is adhered on the outer surface of the middle layer. According to the utility model, the PU synthetic leather layer is adhered on the outer surface of the middle layer made of the neoprene material, so that appearance as well as performances such as wear resistance, flexibility resistance, ageing resistance and mildew resistance of the neoprene material can be improved, and advantages of the neoprene material are kept; and meanwhile, technical problems of easy wearing, easy bending, easy mildew breeding on surface caused by characteristics of the neoprene material are solved.

Description

A kind of composite

Technical field

The utility model relates to technical field of composite materials, especially relates to a kind of composite of multi-layer bonded structure.

Background technology

The general introduction Neoprene of Neoprene (SBR CR Neoprene) material, is commonly called as Neoprene, and Chinese is neoprene.Neoprene is a kind of synthetic rubber foaming body, and feel is fine and smooth, softness, high resilience, have shockproof, insulation, elasticity, waterproof, the feature such as airtight.Chemical composition: make the condensate that monomer, lactic acid polymerizes form by chlorobutadiene.Characteristic and the scope of application: good weatherability, resistance to ozone aging, has self-extinguishment, and oil resistivity is good, and hot strength, extension rate are good, but electrical insulating property, storage-stable are poor, ℃-130 ℃, serviceability temperature-35.Neoprene is used for making the daily necessities bags such as notebook computer inner bag, IPAD bag, computer package, water tumbler bag, ice bag, box lunch bag at present.But because the characteristic of Neoprene causes the easy to wear and deflection of above-mentioned daily necessities bag, surface easily grows the problems such as mould.

Summary of the invention

The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of Neoprene and the bonding composite forming of PU synthetic leather, it has retained the advantage of Neoprene, has solved the easy to wear and deflection and the surperficial technical problem of easily growing mould that because of Neoprene characteristic, cause simultaneously.

To achieve these goals, the technical scheme that the utility model adopts is:

A composite, comprises the intermediate layer of being made by Neoprene, and the outer surface in this intermediate layer is bonded with PU synthetic leather layer.

Wherein, the inner surface in described intermediate layer is also provided with terylene layer of cloth.The edge of described terylene layer of cloth and the inner surface in intermediate layer sew up.

Further, the thickness in described intermediate layer is not less than 1 millimeter, and the thickness of described PU synthetic leather layer is 0.2-0.5 millimeter.

Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:

Compared with prior art, the utility model is bonded with PU synthetic leather layer at the outer surface of Neoprene, PU synthetic leather is current material, its chemical composition is polyurethane. there is gloss soft, nature, soft, the appearance characteristics that kishke feel is strong, also have and substrate bonding excellent performance, resistance to wear, resistance to deflection, anti-aging, the physical characteristics such as resistance to fungi is good, it is good that PU synthetic leather also possesses cold resistance, ventilative, can wash, easy to process, cost is low, waterproof, the advantages such as high resiliency, particularly the adhesive property of PU synthetic leather and Neoprene is good, the outer surface that PU synthetic leather layer is bonded to the intermediate layer of being made by Neoprene can improve the outward appearance of Neoprene and wear-resisting, resistance to deflection, anti-aging, the excellent properties such as resistance to fungi, it has retained the advantage of Neoprene, easy to wear and the deflection and the surperficial technical problem of easily growing mould that because of Neoprene characteristic, cause have been solved simultaneously.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated:

Fig. 1 is structural representation of the present utility model.

In figure, 1: intermediate layer; 2:PU synthetic leather layer; 3: terylene layer of cloth.

The specific embodiment

The following stated is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment, as shown in Figure 1:

A composite, comprises the intermediate layer 1 of being made by Neoprene, and the outer surface in this intermediate layer 1 is bonded with PU synthetic leather layer 2.The outer surface in the intermediate layer 1 that Neoprene is made is bonded with PU synthetic leather layer 2, and it has retained the advantage of Neoprene, has solved the easy to wear and deflection and the surperficial technical problem of easily growing mould that because of Neoprene characteristic, cause simultaneously.This composite can be used for making the daily necessities bags such as notebook computer inner bag, IPAD bag, computer package, water tumbler bag, ice bag, box lunch bag.

Wherein, the inner surface in described intermediate layer 1 is also provided with terylene layer of cloth 3, and terylene layer of cloth 3 can prevent Neoprene surface and articles for use surface abrasion, and the inner surface in the edge of described terylene layer of cloth 3 and intermediate layer 1 sews up, and makes terylene layer of cloth 3 more soft and smooth.

Further, the thickness in described intermediate layer 1 is not less than 1 millimeter, this thickness can guarantee that the intermediate layer 1 of being made by Neoprene has certain bonding hardness, certainly the thickness in intermediate layer 1 is unsuitable blocked up, should determine the thickness that it is suitable according to application, the thickness of described PU synthetic leather layer 2 is 0.2-0.5 millimeter, and this thickness can be given full play to the advantages characteristic of PU synthetic leather, retains preferably the advantages characteristic of Neoprene simultaneously.

The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
