Description

TECHNICAL FIELD

[0001] The utility model relates to a paving site, in particular to a waste conveyor belt woven fabric composite paving coiled material, a paving site and a site. BACKGROUND

[0002] With the rapid development of global industry, as an important carrier of material transportation, the scrap conveyor belt is increasing year by year. The amount of waste conveyor belt produced in China every year is huge, and the traditional treatment methods mainly include incineration, landfill or rough crushing as low-end filler.

[0003] In recent years, the technical scheme of applying waste conveyor belt to sports field paving after physical crushing or chemical regeneration treatment has gradually emerged. The existing technology usually adopts mechanical crushing method to make waste conveyor belt into granular rubber aggregate, and then mixes with adhesive to make prefabricated paving material, which plays an important role in adjusting cost and saving resources.

[0004] But the above scheme is complex in process and produces secondary pollution, and because the internal structure is damaged, the performance of the paving material made is severely reduced. Therefore, some paving materials currently directly use waste conveyor belt as an intermediate layer.

[0005] But because most of the waste conveyor belts recovered at present are coal mine conveyor belts, in order to meet the requirement of flame retardation, the conveyor belts are mostly made of basalt fiber and rubber, and the whole conveyor belt is very hard and has no resilience. If the above conveyor belt is directly used, it will greatly limit the application scene and cannot meet the performance requirements of most living scenes. And crushing into particles will cause secondary pollution and increase cost, so how to reasonably use waste conveyor belt to meet the performance requirements of different sites and realize efficient resource recovery has become a problem to be solved. Utility model content

[0006] The first object of the utility model is to provide a waste conveyor belt woven fabric composite paving coiled material, which solves the problem that the existing waste conveyor belt cannot meet the performance requirements of the site.

[0007] The second object of the utility model is to provide a paving site, which is formed by splicing the waste conveyor belt woven fabric composite paving coiled material.

[0008] The third object of the utility model is to provide a site.

[0009] To achieve the first purpose of the utility model, the utility model provides a kind of waste conveyor belt woven fabric composite paving coiled material, the waste conveyor belt woven fabric composite paving coiled material includes surface layer, woven tensile buffer layer and adhesive layer, surface layer, woven tensile buffer layer and adhesive layer are sequentially arranged from top to bottom;Surface layer is made of synthetic elastomer material, adhesive layer is made of thermoplastic elastomer adhesive or butyl adhesive;Woven tensile buffer layer is formed by transverse weaving strip and longitudinal weaving strip interlaced weaving, wherein at least one of transverse weaving strip and longitudinal weaving strip is formed by cutting waste conveyor belt into strip.

[0010] As can be seen from the above scheme, by cutting the waste conveyor belt into strips, the original hard structure of the waste conveyor belt is changed, and the originally hard waste conveyor belt is changed into easy-to-bend waste conveyor belt strips, and an elastic structure is formed by weaving, and the small gaps generated during weaving increase the shock absorption capacity of the material, so that the waste conveyor belt meets the performance requirements of different scenes without causing secondary pollution and increasing cost. The coiled material of the utility model improves the overall performance, tensile strength, impact strength, elastic recovery and other indicators of the paving material, the tensile strength is greater than or equal to 3.0Mpa, the elongation at break is greater than or equal to 60%, thereby avoiding the occurrence of cracking and cracking of the paving surface layer;Impact absorption is greater than or equal to 35% or more, and the rebound rate is greater than or equal to 35% or more, which is an improvement over the performance indicators of existing paving materials. In addition, cutting the waste conveyor belt into strips can effectively utilize waste conveyor belts of different shapes, sizes and damage levels, so that the width and thickness of the waste conveyor belt are uniform, and by cutting into different specifications of strips and weaving, paving coiled materials of different thicknesses can be prepared according to the needs of different site properties. The setting of the adhesive layer further enhances the connection performance between the paving coiled material and the paving base surface, making the paving performance more stable.

[0011] Further, one of the transverse weaving strip and the longitudinal weaving strip is formed by cutting the waste conveyor belt into strips, and the other of the transverse weaving strip and the longitudinal weaving strip is a woven rope.

[0012] As can be seen from the above scheme, the transverse weaving strip or the longitudinal weaving strip is a woven rope, which makes the weaving of the waste conveyor belt strip more convenient and the process simpler.

[0014] As can be seen from the above scheme, the above woven rope material has the advantages of wide source and low cost, and can also ensure the stability of the connection with the waste conveyor belt.

[0015] Further, both the transverse weaving strip and the longitudinal weaving strip are formed by cutting the waste conveyor belt into strips.

[0016] From the above scheme can be seen, the waste conveyor belt is cut into strips transversely and longitudinally and is cross-woven, and the warp and weft interweaving makes the elasticity of the material uniform in all directions, avoids the occurrence of weak points, and the structure can also make more use of waste materials, and the recycling of waste resources is more sufficient.

[0017] A further scheme is that the waste conveyor belt is a waste conveyor belt treated on the surface by a low-temperature plasma method.

[0018] From the above scheme can be seen, the low-temperature plasma method and the like are used to treat the surface of the waste conveyor belt, thereby improving the surface energy of the waste conveyor belt and increasing the adhesion between the woven buffer layer and other layers.

[0019] A further scheme is that the synthetic elastomer is one of modified polyurethane, ethylene-propylene-diene rubber, SEBS and the like thermoplastic elastomers; and the waste conveyor belt is one of waste fiber-reinforced rubber conveyor belt, waste rubber conveyor belt, waste synthetic resin conveyor belt and waste synthetic fiber conveyor belt.

[0020] From the above scheme can be seen, the synthetic elastomer is non-toxic, odorless, resistant to corrosion of various chemical media, and can meet the physical properties such as wear resistance, slip resistance, impact absorption and strength of the paving roll material, thereby ensuring the service life of the paving roll material. The waste conveyor belt woven fabric can play a role of reinforcing the tensile strength and improving the overall strength of the paving roll material through cutting and weaving, and at the same time, the product manufacturing cost is reduced.

[0021] A further scheme is that the waste conveyor belt woven fabric composite paving roll material further comprises an isolation paper layer, and the isolation paper layer is located below the adhesive layer.

[0022] From the above scheme can be seen, the isolation paper layer is provided, so that the paving roll material is more convenient to transport and use, and when used, the isolation paper layer can be removed to realize effective assembly and bonding.

[0023] In order to achieve the above-mentioned second object, the utility model provides a paving site, which is formed by splicing the waste conveyor belt woven fabric composite paving roll material according to any one of the above schemes.

[0024] From the above scheme can be seen, the waste conveyor belt woven fabric composite paving roll material of the utility model can be made into precast roll materials of different thicknesses according to the requirements of different sites, and when used, only needs to be paved on the base material of the required site, which is convenient to operate and has a wide range of applications.

[0025] A further scheme is that a coating surface layer is further arranged on the surface layer; and the coating surface layer is made of a synthetic elastomer material.

[0026] As can be seen from the above scheme, the waste conveyor belt woven fabric composite paving coiled material is spliced on the paving site, and then a coating surface layer is coated on the surface of the waste conveyor belt woven fabric composite paving coiled material to form a binary structure with the surface layer of the waste conveyor belt woven fabric composite paving coiled material, so as to meet the overall requirement of the surface of the paving site.
