Abstract
The utility model discloses a driving band with flame-retardant effect, which comprises a wrapping cloth layer. A top adhesive layer, a buffer adhesive layer and a bottom adhesive layer are arranged inside the wrapping cloth layer, and tensile bodies combined by a plurality of longitudinal fiber ropes are mixed inside the buffer adhesive layer. A first flame-retardant material layer is arranged between the buffer adhesive layer and the top adhesive layer, and a second flame-retardant material layer is arranged between the buffer adhesive layer and the bottom adhesive layer. The driving band with flame-retardant effect not only is provided with the tensile bodies and increases tensile property, but also protects the tensile bodies through the flame-retardant material layers, and then has a flame-retardant function.
Description
Technical field
The utility model relates to mechanical transmission fields, relates in particular to the driving belt that a kind of transmission is used.
Background technique
To adopt rubber mostly be main material to driving belt in the prior art, a kind of heat-resisting oil-resisting antistatic V band is disclosed in Chinese utility model patent 200620102466.3, be mixed with the tension element that many long grain fiber cotton ropes are formed in its cushion gum layer, the body of rubber material of each glue-line is to be mixed with carbon black in hydrogenated nitrile-butadiene rubber, the glue-line but rubber is hydrocarbon.
The genus hevea combustible material.During burning, can discharge stanch airs such as poisonous and harmful such as a large amount of HCL, produce secondary pollution.
Summary of the invention
The utility model provides a kind of intensity good, has the driving belt of fire retardation.
Show that after deliberation driving belt is when burning, as long as inner tension element is intact, even the local burned destruction of driving belt, but still can keep certain intensity,
A kind of driving belt that has flame retardant effect comprises infantees layer, top glue-line, stretch-resisting layer, cushion gum layer and primer layer.Be mixed with the tension element that many long grain fiber cotton ropes are formed in the stretch-resisting layer, have the first flame retardant material layer between described cushion gum layer and the top glue-line, have the second flame retardant material layer between cushion gum layer and the primer layer.
The utility model driving belt cross section is trapezoidal or triangle.
The thickness of the described first flame retardant material layer and the second flame retardant material layer is 1: 0.5 with cushion gum layer thickness ratio～and 3.
The thickness of suitable flame retardant material layer can play flame retardant effect, the tension element in the protection cushion gum layer.The first flame retardant material layer and the second flame retardant material layer generally can adopt the rubber that is added with fire retardant, and fire retardant can be selected commercially available all kinds fire retardant for use.
Material of main part in the utility model driving belt in top glue-line, cushion gum layer and the primer layer all can adopt versatile material, and can mix reinforcing fiber according to the intensity needs.
This practical driving belt not only has tension element and has improved tensility, and by the protection of flame retardant material layer to tension element, has played fire retardation.
Description of drawings
Fig. 1 is the utility model driving belt cross-sectional configuration schematic representation.
Embodiment
Referring to accompanying drawing, the utility model has the driving belt of flame retardant effect, comprises infantees layer 1, and infantees layer 1 inside has top glue-line 2, cushion gum layer 6 and primer layer 3, is mixed with the tension element 7 that many long grain fiber cotton ropes are formed in the cushion gum layer 6.
Have the first flame retardant material layer 5 between cushion gum layer 6 and the top glue-line 2, have the second flame retardant material layer 4 between cushion gum layer 6 and the primer layer 3.
The driving belt cross section is trapezoidal, and the thickness of the first flame retardant material layer 5 and the second flame retardant material layer 4 is 1: 1.2 with cushion gum layer 6 thickness ratio.
The thickness of suitable flame retardant material layer can play flame retardant effect, the tension element in the protection cushion gum layer 6.The first flame retardant material layer and the second flame retardant material layer generally can adopt the rubber that is added with fire retardant, and fire retardant can be selected commercially available all kinds fire retardant for use.
