Abstract

The utility model discloses a clad material that is used for padding the fluid, which comprises a PVC inner layer and a PU outer layer that is coated on the outer surface of the PVC inner layer. The PVC inner layer is of a polyvinyl chloride rubberized fabric and is provided with a padding space that is melted by high cyclic wave and is used for padding the fluid. The PU outer layer is of polyurethane material, and has the advantages such as flexibility, mildew resistance, grease resistance, chemicals resistance, uneasy falling, and the like, and can effectively improve the tactile impression of the product, and has application safety.

Description

The coating material that is used for fill fluid

Technical field

The utility model relates to a kind of coating material, is meant a kind of coating material that is used for fill fluid especially.

Background technology

Existing inflatable toys, air mattress and water bed etc., mostly be with polyvinyl chloride (Polyvinyl Chloride, PVC) adhesive plaster is a base material, because the PVC adhesive plaster has intensity height, drug resistance, fluid barrier performance and flexibility, the most important thing is to be beneficial to high frequency processing, the packing space that the PVC adhesive plaster is inserted in conjunction with fluids such as forming water supply and air.

But the PVC material can distribute pungent chemical substance taste, though and have a flexibility, but whole sense of touch is still not good, still easily cause the skin discomfort during friction skin, importantly, the main material vinyl chloride (VCM) of PVC, and the plasticiser DINP (Diisononyl phthalate) that adds in the manufacture process, meeting is because directly contact with human body, and generation endangers to human body, causes many chronic diseases, as chorionitis, cholangiocarcinoma, the cancer of the brain, allergy ... Deng, and can't satisfy user demand.

Consulting Fig. 1, Fig. 2, is example with water bed 1, mainly includes a base material 11, and a tapetum 12.This base material 11 is that (Polyvinyl Chloride, PVC) material are formed for a packing space 10 of fill fluid to a kind of polyvinyl chloride through the high frequency welding.This tapetum 12 is to plant at this base material 11 1 outer surfaces 111.Whereby, intercept this base material 11 with this tapetum 12 and directly contact, and can improve the not good disappearance of aforementioned PVC material sense of touch with its compliance with human body.

Because tapetum 12 is to be formed on this base material 11 outer surfaces 111 in the mode that plants, and not only processes the handling procedure complexity, and attaches dust easily, or this base material 11 breaks away from certainly, normal cause the respiratory illness, and still can produce harm, the doubt on safe in utilization is arranged human body.

The utility model content

The purpose of this utility model is to provide a kind of coating material that is used for fill fluid that can promote sense of touch and safety in utilization.

Of the present utility model being characterised in that: the coating material that this is used for fill fluid, comprise a PVC internal layer, and a PU skin.This PVC internal layer is that (Polyvinyl Chloride, PVC) adhesive plaster are formed for a packing space of fill fluid to a kind of polyvinyl chloride through the high frequency welding.This PU skin is that (Polyurethane, PU) material are coated on this PVC internal layer one outer surface to a kind of aqueous polyurethane.

Effect of the present utility model is can be by compliance, antifungi, grease resistance and chemicals, the difficult drop-off of this PU material ... etc. characteristic, effectively promote the sense of touch of goods, and the security on using.

Description of drawings

Fig. 1 is a stereogram, and general water bed is described.

Fig. 2 is a cutaway view, illustrates that aforementioned water bed has a PVC base material and a tapetum.

Fig. 3 is a cutaway view, illustrates that the utility model is used for one first preferred embodiment of the coating material of fill fluid.

Fig. 4 is a cutaway view, illustrates that the utility model is used for one second preferred embodiment of the coating material of fill fluid.

The specific embodiment

Below by most preferred embodiment and accompanying drawing the coating material that is used for fill fluid of the present utility model is elaborated.

Consult Fig. 3, one first preferred embodiment that the utility model is used for the coating material of fill fluid comprises a PVC internal layer 2, and a PU skin 3.

This PVC internal layer 2 is that (Polyvinyl Chloride, PVC) adhesive plaster are formed for a packing space 20 of fill fluid to a kind of polyvinyl chloride through the high frequency welding.This fluid can be gas or liquid.

This PU outer 3 is that (Polyurethane, PU) material be to be coated on this PVC internal layer 2 one outer surfaces 21, and thickness are not more than 10 microns for a kind of water-based or solvent borne polyurethane.In this preferred embodiment, this PU skin 3 is that (Polyurethane after PU) material is coated these PVC internal layer 2 outer surfaces 21, finalizes the design in this PVC internal layer 2 outer surfaces 21 through oven dry with aqueous polyurethane.Aforementioned bake out temperature circle is in 80 ℃～120 ℃.

Whereby, because aforementioned polyurethane (Polyurethane, PU) material has compliance, wear-resisting, antifungi, grease resistance and chemicals, difficult drop-off ... etc. characteristic, therefore, this PU skin 3 not only can intercept this PVC internal layer 2 and directly contact with human body, and the no grease in outer 3 surfaces of this PU, colourless, the pungent peculiar smell, incrust of nothing, also can not attach dust, and can provide preferable sense of touch, so, not only can promote the comfortableness in the use, and can reduce harm, promote safety in utilization human body.

Consulting Fig. 4, is the utility model one second preferred embodiment, and itself and this first preferred embodiment is roughly the same, difference be in:

Be doped with 5%～15% functional material 31 in this PU skin 3.This functional material 31 can be micron order or nano level silver particles, material with carbon element, far-infrared ray material, anion material, and any the above combination of flake nano mica.

Because silver particles has antibacterial, antibacterial functions, material with carbon element has deodorizing, bacteria resistance function, far-infrared ray material, anion material can discharge far infrared, the anion to the human body beneficial, therefore, can make to the utlity model has good antibacterial, antibiotic, deodorizing effect, and with improving human body, strengthening healthy effect.And the flake nano mica has resistance to scraping, choke, from shape ... etc. characteristic, can make the utility model that the effect of waterproof is arranged.

According to the above as can be known, the coating material that is used for fill fluid of the present utility model has following advantage and effect: because the utility model is to intercept PVC internal layer 2 with PU outer 3, therefore, not only processing place is easy, cost is lower, and the no grease in outer 3 surfaces of this PU, colourless, there is not pungent peculiar smell, incrust, can not attach dust, and can provide preferable sense of touch, also can add aforementioned functional material 3, improve human body, strengthen healthy, reach effect with waterproof, so, comfortableness and practicality in the use not only can be promoted, and can reduce harm, promote safety in utilization human body.
