Description

Technical Field

[0001] This utility model relates to the field of laminate technology, and in particular to a phenolic resin glass cloth laminate. Background Technology

[0002] Phenolic resin glass cloth laminate is a laminated product made by hot pressing chemically treated alkali-free electrical fiber cloth as the base material and phenolic resin as the adhesive. It exhibits high mechanical strength at high temperatures and good electrical performance stability under high humidity, making it suitable for applications in machinery, electrical appliances, and electronics. The surface should be smooth and flat, free from bubbles, impurities, and other obvious defects. Minor scratches are permissible. Edges should be neatly cut, and the cross-section should be free from delamination and cracks.

[0003] Existing phenolic resin glass cloth laminates are easily damaged during transportation and storage after production, especially at the corners, due to external impacts and other factors, which increases the property losses of manufacturers. Furthermore, gaps easily form between the layers of existing phenolic resin glass cloth laminates after long-term use, allowing dust and water to enter and quickly damage the laminates, reducing their service life.

[0004] Therefore, it is necessary to invent a phenolic resin glass cloth laminate to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a phenolic resin glass cloth 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 resin glass cloth laminate, comprising a laminate assembly, wherein protective sleeve assemblies are sleeved at the four corners of the outer side wall of the laminate assembly;

[0007] The laminate assembly includes a melamine-formaldehyde resin layer, and fiberglass cloth layers are adhered to both the top and bottom ends of the melamine-formaldehyde resin layer.

[0008] The protective sleeve assembly includes a sleeve body, and an elastic buffer layer is fixedly provided on the outer side wall of the sleeve body.

[0009] Preferably, a phenolic resin layer is adhered to the side of the fiberglass cloth layer away from the melamine-formaldehyde resin layer, and a reinforcing plate is adhered to the side of the phenolic resin layer away from the fiberglass cloth layer.

[0010] Preferably, the phenolic resin layer has multiple grooves on the side near the reinforcing plate, and the multiple grooves are distributed at equal intervals.

[0011] Preferably, the reinforcing plate is integrally formed with reinforcing ribs on the side near the phenolic resin layer, which correspond one-to-one with the multiple sinks, and the reinforcing ribs are adapted to the sinks.

[0012] Preferably, a plurality of connecting strips arranged in a rectangular array are integrally formed between the two reinforcing plates, and the connecting strips penetrate the melamine-formaldehyde resin layer, the two fiberglass cloth layers and the phenolic resin layer. A plurality of slots are provided at the four corners of the side of the reinforcing plate away from the phenolic resin layer.

[0013] Preferably, the inner walls of the top and bottom ends of the sheath body are integrally formed with buckles that correspond one-to-one with multiple slots, and the buckles are adapted to the slots.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This invention utilizes two reinforcing plates made of high-density polyethylene, which possess excellent rigidity and toughness, high strength, and corrosion resistance. This gives the laminate excellent bending resistance and corrosion resistance. Multiple connecting strips connect the two reinforcing plates, forming a unified whole between the melamine-formaldehyde resin layer, the two fiberglass cloth layers, and the phenolic resin layer. This effectively prevents the laminate from cracking and extends its service life. Furthermore, protective sleeve assemblies at the four corners of the laminate provide elastic cushioning, protecting the corners from impact damage and facilitating transportation and storage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-5 The phenolic resin glass cloth laminate shown includes a laminate assembly 1, and protective sleeve assemblies 2 are sleeved at the four corners of the outer side wall of the laminate assembly 1.

[0024] Furthermore, the laminate assembly 1 includes a melamine-formaldehyde resin layer 101. Fiberglass cloth layers 102 are adhered to both the top and bottom ends of the melamine-formaldehyde resin layer 101. A phenolic resin layer 103 is adhered to the side of the fiberglass cloth layer 102 away from the melamine-formaldehyde resin layer 101. A reinforcing plate 104 is adhered to the side of the phenolic resin layer 103 away from the fiberglass cloth layer 102. Multiple grooves 105 are formed on the side of the phenolic resin layer 103 near the reinforcing plate 104, and the grooves 105 are evenly spaced. A reinforcing rib 106 is integrally formed on the side of the reinforcing plate 104 near the phenolic resin layer 103, corresponding one-to-one with the grooves 105. The reinforcing rib 106 is adapted to the grooves 105. The arrangement of the reinforcing rib 106 and the grooves 105 improves the strength of the reinforcing plate 104, further enhancing the strength of the laminate. The two reinforcing plates 104... Multiple connecting strips 107 arranged in a rectangular array are integrally formed between the 04 layers, and the connecting strips 107 penetrate the melamine-formaldehyde resin layer 101, the two fiberglass cloth layers 102, and the phenolic resin layer 103. The two reinforcing plates 104 are made of high-density polyethylene, which has good rigidity and toughness, high strength, and corrosion resistance, enabling the laminate to have good bending resistance and corrosion resistance. At the same time, multiple connecting strips 107 are set between the two reinforcing plates 104, so that the melamine-formaldehyde resin layer 101, the two fiberglass cloth layers 102, and the phenolic resin layer 103 between the two reinforcing plates 104 form a whole, effectively preventing the laminate from cracking and improving its service life. Multiple slots 108 are provided at the four corners of the side of the reinforcing plate 104 away from the phenolic resin layer 103.

[0025] The protective sleeve assembly 2 includes a sleeve body 201. An elastic buffer layer 202 is fixedly provided on the outer wall of the sleeve body 201.

The buckles 203 are adapted to the slots 108. The protective sleeve assembly 2 is set at the four corners of the laminate. The elastic buffer layer 202 has a good cushioning effect, which can protect the corners of the laminate from collision damage, and facilitate transportation and storage. The buckles 203 and the slots 108 can make the protective sleeve assembly 2 securely fastened to the corners of the laminate to prevent it from falling off. When the laminate is in use, the protective sleeve assembly 2 can be removed without affecting the use of the laminate.

[0026] Working principle of this utility model:

[0027] In use, the reinforcing plate 104 is made of high-density polyethylene, which has excellent rigidity and toughness, high strength, and corrosion resistance, giving the laminate excellent bending resistance and corrosion resistance. At the same time, multiple connecting strips 107 are set between the two reinforcing plates 104, so that the melamine-formaldehyde resin layer 101, the two fiberglass cloth layers 102, and the phenolic resin layer 103 between the two reinforcing plates 104 form a whole, effectively preventing the laminate from cracking. Protective sleeve assemblies 2 are set at the four corners of the laminate, and the elastic buffer layer 202 has a good cushioning effect, which can protect the corners of the laminate from collision damage, and facilitate transportation and storage.
