[0001] This utility model relates to the technical field of phenolic cotton fabric laminates, and in particular to a phenolic cotton fabric laminate. Background Technology
[0002] Phenolic cotton fabric laminate is made by impregnating cotton fabric with phenolic resin, followed by drying and hot pressing. It possesses high mechanical properties and is suitable for use as insulating structural components in machinery, motors, and electrical equipment. It can also be used in transformer oil and is suitable for making mechanical parts such as rubberized gear bearings and guide wheels. The surface of the phenolic cotton fabric laminate should be smooth, free from bubbles, pinholes, and impurities; a small number of spots are permissible. Edges should be neatly cut, and end faces should be free from delamination and cracks.
[0003] The existing phenolic cotton fabric laminate technology has the following problems: the adhesion between the layers of the phenolic cotton fabric laminate is poor, and cracks are easily generated after long-term use, allowing dust and water to enter the cracks, causing the layers to break apart quickly and making it unusable. In addition, the edges of the phenolic cotton fabric laminate are prone to wear and collapse, affecting normal use.
[0004] Therefore, it is necessary to invent a phenolic cotton fabric laminate to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a phenolic cotton fabric laminate to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a phenolic cotton fabric laminate, comprising an adhesive layer assembly, wherein a cotton fabric layer assembly is adhesively disposed at both the top and bottom ends of the adhesive layer assembly, and an edge-binding component is adhesively disposed around the outer side wall of the adhesive layer assembly;
[0007] The adhesive layer assembly includes an adhesive layer body, and countersunk holes are provided at both the top and bottom ends of the adhesive layer body;
[0008] The cotton fabric layer assembly includes a cotton fabric layer body, and a reinforcing component assembly is fixedly disposed on the side of the cotton fabric layer body near the adhesive layer body;
[0009] The edging assembly includes a edging that extends to the outside of the cotton fabric layer assembly at its top and bottom ends, respectively.
[0010] Preferably, the countersunk holes are provided in multiple locations, and the multiple countersunk holes are distributed in a rectangular array.
[0011] Preferably, there are multiple reinforcing assemblies, which are arranged in a rectangular array. Each of the multiple reinforcing assemblies corresponds to a single countersunk hole, and the reinforcing assemblies are adapted to the countersunk holes.
[0012] Preferably, the reinforcing assembly includes an extension post, on which a plurality of connecting covers are integrally formed and sleeved, and the connecting covers are tapered.
[0013] Preferably, the top and bottom of the inner sidewall of the edging are integrally formed or even have an extended edge, which extends to the edge of the cotton fabric body away from the adhesive layer body.
[0014] Preferably, the inner sidewall of the perimeter is integrally formed with multiple reinforcing ribs, and the multiple reinforcing ribs are distributed at equal intervals.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] This invention features multiple reinforcing assemblies on the side of the cotton fabric layer assembly near the adhesive layer assembly. These reinforcing assemblies significantly increase the contact area between the cotton fabric layer assembly and the adhesive layer assembly, thereby enhancing the adhesive strength. Furthermore, the multiple connecting covers on the reinforcing assemblies are conical in shape, providing reverse tension to ensure a stronger bond between the two cotton fabric layer assemblies and reduce the likelihood of cracking. Simultaneously, the edge-wrapping assembly protects the entire edge of the laminate, preventing dust and water from entering. The multiple reinforcing ribs further strengthen the edge protection, safeguarding the laminate edge and preventing collapse or damage. Attached Figure Description
