Description
技术领域 technical field
本实用新型属于煤矿输送管道技术领域，尤其涉及一种煤矿井下用钢骨架纤维增强树脂管。 The utility model belongs to the technical field of coal mine conveying pipelines, in particular to a steel frame fiber reinforced resin pipe for underground coal mines.
背景技术 Background technique
在煤矿井下的通风系统、抽放瓦斯系统、喷浆系统、供排水系统，需要使用大量的输送管道，当前的输送管道大多采用不锈钢管、无缝钢管、PE管、PVC管或玻璃钢管。不锈钢管、无缝钢管虽然强度大，但是使用成本高，且由于煤矿井下环境恶劣，不锈钢管或无缝钢管易被腐蚀，使用寿命较短。PE管、PVC管或玻璃钢管虽然成本较低，但抗静电性差，在施工中容易产生裂缝，对安全生产造成一定威胁。 Ventilation systems, gas drainage systems, spraying systems, and water supply and drainage systems in coal mines require a large number of pipelines. Most of the current pipelines use stainless steel pipes, seamless steel pipes, PE pipes, PVC pipes or glass steel pipes. Although stainless steel pipes and seamless steel pipes have high strength, they are expensive to use, and due to the harsh environment in coal mines, stainless steel pipes or seamless steel pipes are easily corroded and have a short service life. Although the cost of PE pipes, PVC pipes or glass steel pipes is low, they have poor antistatic properties and are prone to cracks during construction, posing a certain threat to safe production.
实用新型内容 Utility model content
本实用新型要解决的技术问题就是提供一种成本较低、耐腐蚀、阻燃抗静电、抗弯强度高、抗冲击性能强的煤矿井下用钢骨架纤维增强树脂管。 The technical problem to be solved by the utility model is to provide a steel skeleton fiber-reinforced resin pipe for coal mine underground with low cost, corrosion resistance, flame retardant and antistatic, high bending strength and strong impact resistance.
为解决上述技术问题，本实用新型采用的技术方案为：包括管体，所述管体的内部为抗磨防渗内衬层，抗磨防渗内衬层外粘接有镀锌钢丝网骨架构成的强力层，在强力层的表面上粘接缠绕致密的表面导电层。 In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: comprising a pipe body, the inside of which is an anti-wear and anti-seepage lining layer, and a galvanized steel wire mesh skeleton is bonded outside the anti-wear and anti-seepage inner lining layer The strength layer is formed, and a dense surface conductive layer is bonded and wound on the surface of the strength layer.
其附加技术特征为：所述强力层的镀锌钢丝网骨架为方孔网，网孔尺寸为3——4mm，钢丝直径为0.4——1mm；所述强力层的缠绕角度为67.79°。 Its additional technical features are: the galvanized steel wire mesh skeleton of the strength layer is a square mesh, the mesh size is 3-4mm, and the steel wire diameter is 0.4-1mm; the winding angle of the strength layer is 67.79°.
本实用新型提供的煤矿井下用钢骨架纤维增强树脂管，管体的内部为抗磨防渗内衬层，抗磨防渗内衬层外粘接有镀锌钢丝网骨架构成的强力层，在强力层的表面上粘接缠绕致密的表面导电层。制造时，先将聚酯纤维与加入高效环保无毒的无卤阻燃剂、阴离子型抗静电剂、碳纳米管和纳米钛白粉的树脂固化后形成抗磨防渗内衬层，然后在抗磨防渗内衬层成型的基础上编织镀锌钢丝网骨架并进行焊接同时均匀涂敷具有阻燃和导电特性的热固性树脂粘合剂形成强力层，最后在强力层的表面上缠绕致密的纤维同时均匀涂覆加有碳纳米管做改性剂的具有强导电和阻燃特性的热固性树脂粘合剂形成表面导电层。本实用新型提供的煤矿井下用钢骨架纤维增强树脂管在设计中采取三大措施：首先是在具有导电和阻燃特性的热固性树脂粘合剂中加配了改善复合管各层微观结构的纳米钛白粉做填料，从而提高塑料和纤维之间的亲和力，提高它的结构强度、柔韧性和弹性模量；再者是在具有导电和阻燃特性的热固性树脂粘合剂中加配了改善复合管各层导电性能的碳纳米管做改性剂；最后是在强力层设置了由编织镀锌钢丝网组成的钢骨架并进行焊接处理，缠绕角度为67.79°，改变了缠绕角度为54.73°的传统选择。通过改变缠绕角，层厚度可减少22%左右，因为在常温情况下矿用管道的环向拉伸强度与轴向拉伸强度之比设计为（4-5）：1是完全可行的。改变缠绕角是改变定长缠绕玻璃钢管道环向与轴向拉伸强度之比的主要措施。增大缠绕角对定长缠绕工艺更为有利。适当增大缠绕角，减小管道的厚度，仍不会降低轴向强度安全系数，这样可以大幅度降低工程造价。它借助超细钛白粉的亲和作用，使其与基础纤维和热固化材料紧密结合，产生较强的抗裂能力和抗冲击负荷的优良弹性，使管道具有较良好的抗弯能力。其次强力层为纤维状材料，与同质地的块状材料相比它的强度要高得多。钢骨架焊接纤维增强树脂管的各项力学性能有了很大的提高，强度的增加可适当减少各层的厚度，减轻了管材重量；同时由于在钢骨架和热固性塑料之间填充有多壁碳纳米管和纳米钛白粉，改变各层精细结构的同时加强了其抗弯强度和抗冲击能力，耐磨性能和导电能有了很大提高。 The utility model provides a steel skeleton fiber-reinforced resin pipe for underground coal mines. The inside of the pipe body is an anti-wear and anti-seepage inner lining, and a strong layer composed of a galvanized steel wire mesh skeleton is bonded outside the anti-wear and anti-seepage inner lining. A dense surface conductive layer is bonded and wound on the surface of the strength layer. During manufacture, the polyester fiber is first cured with a resin added with highly efficient, environmentally friendly and non-toxic halogen-free flame retardants, anionic antistatic agents, carbon nanotubes and nano-titanium dioxide to form an anti-wear and anti-seepage lining layer, and then the anti-wear and anti-seepage lining is formed On the basis of forming the anti-seepage lining layer, weave the galvanized steel wire mesh skeleton and weld it, and at the same time uniformly coat the thermosetting resin adhesive with flame-retardant and conductive properties to form a strong layer, and finally wind dense fibers on the surface of the strong layer At the same time, a thermosetting resin adhesive with strong conductivity and flame-retardant properties added with carbon nanotubes as a modifier is evenly coated to form a surface conductive layer. The utility model adopts three major measures in the design of the steel skeleton fiber reinforced resin pipe used in underground coal mines: firstly, adding nano-titanium to improve the microstructure of each layer of the composite pipe in the thermosetting resin adhesive with conductivity and flame retardancy White powder is used as filler to improve the affinity between plastic and fiber, and improve its structural strength, flexibility and elastic modulus; moreover, it is added to the thermosetting resin binder with conductivity and flame retardant properties to improve the composite pipe. Carbon nanotubes with layer conductivity are used as modifiers; finally, a steel skeleton composed of woven galvanized steel wire mesh is installed on the strength layer and welded. The winding angle is 67.79°, which changes the traditional choice of winding angle of 54.73° . By changing the winding angle, the thickness of the layer can be reduced by about 22%, because the ratio of the hoop tensile strength to the axial tensile strength of the mine pipeline is designed to be (4-5): 1 at room temperature, which is completely feasible. Changing the winding angle is the main measure to change the ratio of the circumferential and axial tensile strength of the fixed-length wound FRP pipe. Increasing the winding angle is more beneficial to the fixed-length winding process. Appropriately increasing the winding angle and reducing the thickness of the pipe will not reduce the axial strength safety factor, which can greatly reduce the project cost. With the help of the affinity of ultra-fine titanium dioxide, it is closely combined with the basic fiber and thermosetting material, resulting in strong crack resistance and excellent elasticity against impact load, so that the pipe has better bending resistance. Secondly, the strength layer is a fibrous material, and its strength is much higher than that of a homogeneous block material. The mechanical properties of the steel frame welded fiber reinforced resin pipe have been greatly improved, and the increase in strength can appropriately reduce the thickness of each layer and reduce the weight of the pipe; Nanotubes and nano-titanium dioxide change the fine structure of each layer while enhancing its bending strength and impact resistance, and its wear resistance and electrical conductivity have been greatly improved.
