Summary of the invention
The purpose of this utility model is to provide a kind of liquid conveying hose, and the inside and outside glue-line of flexible pipe is same material not, can satisfy inside and outside glue-line difference in functionality demand.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of liquid conveying hose comprises the inner glue layer of pipe and pipe inner and outer surface and outer glue-line, and described inner glue layer is the polyurethane of polyurethane or adding additive with the material of outer glue-line.
In the such scheme, described polyurethane is thermoplastic polyurethane.
In the such scheme, described additive is one or more in plastics, rubber, carbon black, antioxidant, ultraviolet-resistant absorbent, anti-mould microbial inoculum and the fire retardant.
Compared with prior art, the beneficial effect of technical solutions of the utility model generation is as follows:
The utility model can be different to glue-line inside and outside the flexible pipe according to the user usage requirement, choose different sizing materials, can be when reducing cost, enlarge the using scope of flexible pipe.
Description of drawings
