Description
Technical field
The present invention relates to a kind of handrail, relate in particular to a kind of permanent seal cooling handrail, specifically be applicable to not fragile on the escalator, difficult aging handrail.
Background technology
At present, escalator has obtained very big application in society, and especially on supermarket and other places, purposes very extensively.For the handrail to escalator is protected, handrail need be set above that.Handrail commonly used mainly is made up of decorative layer, tension internal layer and canvas layer, and the tension internal layer occupy between decorative layer, the canvas layer.
The Chinese patent Granted publication number is CN101323409B; Granted publication day is that the patent of invention on June 9th, 2010 discloses a kind of handrail; It possesses tension thing, core layer, decorative layer and canvas layer, and wherein, the tension thing is at longitudinal extension; The core layer uses the core layer around the tension thing, to form cross sectional shape C word shape with the plasticity elastic; Decorative layer uses decorative layer to form cross sectional shape C word shape in the outside of the cross sectional shape C of core layer word shape with the thermoplastic elastic thing, and canvas layer is formed on the inner face of the cross sectional shape C word shape of core layer, and the core layer is identical with the material and the hardness of thermoplastic elastic thing with said decorative layer with the thermoplastic elastic thing.Though the core layer and the decorative layer of this invention have all used thermoplastic material, its material property is relatively poor, resistance to abrasion a little less than, resistance to corrosion is not strong, in use, not only frays easily, and easy ageing, embrittlement, service life is lower.
Summary of the invention
The objective of the invention is to overcome that the resistance to abrasion that exists in the prior art is weak, resistance to corrosion is not strong; Be prone to aging, embrittlement, defective that service life is lower and problem provide that a kind of resistance to abrasion is strong, resistance to corrosion is strong; Be difficult for aging, embrittlement, the permanent seal cooling handrail that service life is long.
For realizing above purpose; Technical solution of the present invention is: a kind of permanent seal cooling handrail; Comprise inner core ` tensile layer, canvas layer and decorative layer; Said tensile layer is arranged on the inside of inner sandwich layer, and the upper surface of inner sandwich layer is connected with the inside face of decorative layer, and the lower surface of inner sandwich layer is connected with the upper surface of canvas layer; The constituent of said inner sandwich layer and weight portion ratio thereof are: polypropylene 5-15, poly-vinyl 5-15, polyurethane 5-15, epoxy resin 3040, phenol resin 30-40.
The constituent of said inner sandwich layer and weight portion ratio thereof are: polypropylene 10, poly-vinyl 10, polyurethane 10, epoxy resin 35, phenol resin 35.
The constituent of said decorative layer and weight portion ratio thereof are: thermoplastic base resin 60-70, ethylene propylene diene rubber 20-30, ethanol 5-15.
The constituent of said decorative layer and weight portion ratio thereof are: thermoplastic base resin 65, ethylene propylene diene rubber 25, ethanol 10.
The fusion temperature of said polypropylene, poly-vinyl, polyurethane, epoxy resin and phenol resin is 200-300 ℃.
The fusion temperature of said polypropylene, poly-vinyl, polyurethane, epoxy resin and phenol resin is 230 ℃.
Compared with prior art, beneficial effect of the present invention is:
1, constituent and the weight portion ratio thereof owing to inner sandwich layer in a kind of permanent seal cooling handrail of the present invention is: polypropylene 5-15; Poly-vinyl 5-15, polyurethane 5-15, epoxy resin 30-40; Phenol resin 30-40; This design not only can improve the tensile strength of inner sandwich layer, and can strengthen the resistance to corrosion of inner sandwich layer, makes it be difficult for aging, embrittlement.Therefore not only tensile strength is bigger in the present invention, and resistance to corrosion is stronger, is difficult for aging, embrittlement.
2, owing to not only the constituent of inner sandwich layer has been carried out exclusive design in a kind of permanent seal cooling handrail of the present invention; And to the more position of friction on the handrail, promptly the constituent of decorative layer also designs, and the constituent of decorative layer and weight portion ratio thereof are: thermoplastic base resin 60-70; Ethylene propylene diene rubber 20-30; Ethanol 5-15, this design not only can improve the resistance to abrasion of decorative layer, and can prevent that it is corroded.Therefore not only resistance to abrasion is stronger in the present invention, and resistance to corrosion is stronger.
