Abstract
A rubber conveyer belt is composed of an upper covering layer, a skeleton layer made of impregnated aramid netted braided fabric with several electrically conducting fibres, a binding layer between said skeleton layer and upper and lower covering layers, and a lower covering layer. The upper and lower covering layers are made of a blended rubber material with polyether polyurethane and methyl vinyl silica gel as main bodies. The framework layer is a gummed aramid cord fabric with a mesh weaving structure woven with a plurality of conductive fibers, copper conductive fibers are wound on a single aramid cord, the wound aramid cord is woven into a mesh structure, and the mesh structure is formed after glue spreading. The adhesive used in the bonding layer is a polyurethane adhesive, and is characterized in that the rubber conveying belt with high and low temperature resistance, wear resistance, oil resistance, weather resistance and good electrical conductivity is finally obtained.
Description
Technical Field
The utility model relates to a rubber conveyer belt.
Background
Conveyor belts are conventional means of transporting and carrying materials. With the rapid development of science and technology and the continuous improvement of mechanical automation level, the requirement on the performance of the conveying belt is higher and higher.
The conveying belt taking the aramid fiber fabric as the framework reinforcing layer is widely valued due to the obvious characteristic of high tensile strength, is widely applied abroad, and is late in development due to the limitation of aramid fiber resources and price in China, so that the existing domestic rubber conveying belt taking the aramid fiber fabric as the framework layer generally has the technical key of incomplete performance characteristics, short service life and how to solve the contradictions between wear resistance and high and low temperature resistance, wear resistance and weather and aging resistance. In addition, the safety production is ensured under the automatic condition, and the hidden danger of static electricity generated by conveyed materials must be eliminated in time while the comprehensive mechanical performance of the domestic rubber conveying belt is comprehensively improved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses main aim at provides a have high low temperature resistance, wearability, oil resistance, weatherability and electrically conductive rubber conveyer belt simultaneously.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the rubber conveyer belt is structurally composed of an upper covering layer, a framework layer, a bonding layer and a lower covering layer, wherein the framework layer is a gumming aramid fiber mesh braided fabric woven with a plurality of conductive fibers, and the framework layer is bonded with the upper covering layer and the lower covering layer into a whole through the bonding layer.
The upper and lower covering layers are made of a blended rubber material with polyether polyurethane and methyl vinyl silica gel as main bodies.
The framework layer is a gummed aramid cord fabric with a mesh weaving structure woven with a plurality of conductive fibers, copper conductive fibers are wound on a single aramid cord, the wound aramid cord is woven into a mesh structure, and the mesh structure is formed after glue spreading.
The adhesive used by the bonding layer is a polyurethane adhesive, and the thickness of the bonding layer is about 1.0 mm.
Compared with the prior art, the utility model is characterized in that: the upper covering layer and the lower covering layer are made of polyurethane and silica gel blends serving as main rubber materials, and the high-low temperature resistance and weather aging resistance of the polyurethane can be improved under the condition that the original performance of the polyurethane is not influenced; the conductive fiber is woven in the net-shaped structure of the aramid cord fabric, so that static electricity generated by friction can be timely output in the use process of the conveyer belt, and the rubber conveyer belt with good high and low temperature resistance, wear resistance, oil resistance, weather resistance and conductivity is finally obtained.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1 is an upper covering layer 2, a bonding layer 3, a framework layer 4, a lower covering layer 5 and conductive fibers.
Detailed Description
The structure of the present invention and the manner of attaining it by those skilled in the art are described in detail below with reference to the accompanying drawings. The embodiments described below are by way of example only, and other obvious variations will occur to those skilled in the art.
Examples
As shown in fig. 1, the rubber conveyor belt provided by this embodiment includes an upper covering layer (1), a framework layer (2), an adhesive layer (3), and a lower covering layer (4), the adhesive layer (3) is respectively disposed on two sides of the framework layer (2), the framework layer (2) is bonded with the upper covering layer (1) and the lower covering layer (4) into a whole through the adhesive layer (3), and the framework layer (2) includes a plurality of conductive fibers (5) woven in a mesh fabric.
The upper covering layer (2) and the lower covering layer (2) are made of rubber materials, polyether polyurethane and methyl vinyl silica gel are mixed with rubber materials through an open mill, then dried compounding agent small materials are added, the mixture is mixed uniformly and is taken out, segmented vulcanization is carried out on a flat vulcanizing machine after the mixture is parked, the polyurethane adhesive is ground, dirt is removed and coated after the mixture is cut according to specifications, the thickness of the bonding layer is about 1.0mm, and then the bonding layer is segmented and pressed through a cold press.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. Those skilled in the art will appreciate that: the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only based on the principle of the present invention, without departing from the spirit and scope of the present invention, the present invention can also have various changes and improvements, and these all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
