[0026] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0027] Example:
[0028] This embodiment introduces a processing technology for winding materials. Figure 1 , 2 As shown, Figure 1 This is a processing process flow of a winding material of the present invention. Figure 2 It is a schematic diagram of the processing technology of the winding material.
[0029] A process for processing a winding material comprises the following steps:
[0030] Step 1: Send the glass fiber cloth 1 into the impregnation area 2 through a conveying system and impregnate it in the pre-prepared epoxy resin.
[0031] Before impregnating the fiberglass cloth, prepare epoxy resin with appropriate viscosity so that the fluidity of the epoxy resin is moderate during the subsequent impregnation; prepare the fiberglass cloth and ensure that its surface is clean and free of impurities to facilitate the penetration and bonding of the resin.
[0032] Furthermore, the concentration range of the epoxy resin required for the impregnation in step 1 is 40% to 60%.
[0033] Furthermore, the temperature of the epoxy resin used for impregnation in step 1 is 150° C. to 180° C. to ensure that the resin has moderate fluidity and fully penetrates the glass fiber cloth.
[0034] Furthermore, in step 1, the impregnation time of the glass fiber cloth varies according to the proportion of the epoxy resin, and the impregnation time ranges from 3 minutes to 60 minutes.
[0035] In this embodiment, a glass fiber cloth with a content of 50%, an epoxy resin of 42.5%, and a flame retardant filler of 7.5% is prepared, and the impregnation time is about 30 to 40 minutes. During this period, the impregnation of the glass fiber cloth is observed and the impregnation time is fine-tuned according to the actual impregnation situation, and the best impregnated glass fiber cloth has been obtained.
[0036] Step 2: The soaked glass fiber cloth enters the roller pressing area 3 of the roller mechanism 1 for heating and curing.
[0037] In the step 2, the temperature at which the impregnated glass fiber cloth 1 is heated and cured is 85° C. to 180° C.
[0038] Further, the glass fiber cloth 1 enters the rolling zone 3 in step 2, and the rollers in the rolling zone 3 heat and solidify the glass fiber cloth 1, and the heating temperature of the rollers decreases from high to low until the glass fiber cloth 1 is output from the rolling zone 3 to the winding mechanism 4. In this embodiment, Figure 3 As shown, Figure 3It is a schematic diagram of the rollers in the rolling zone in the preferred embodiment. In order to make the heating temperature of the glass fiber cloth uniform, there are 8 pairs of rollers 31 in the roller mechanism. When the glass fiber cloth just enters the rolling zone, the temperature of the first 4 pairs of rollers is 180°C. The glass fiber cloth is output backward with the rollers, passing through 3 pairs of rollers 31 with a temperature of 150°C, and finally passing through the last pair of rollers 31 with a temperature of 85°C. As the roller temperature continues to drop, the rollers run at 3 to 5 m / min to complete the high-temperature curing of the impregnated glass fiber cloth. The above-mentioned roller forming with temperature changes is conducive to improving the physical properties of the glass fiber cloth as a coil.
[0039] Step 3: adjusting the roller gap in the rolling zone 2 to obtain a glass fiber cloth with a rolling thickness of T.
[0040] As the glass fiber cloth is heated and rolled in the rollers, it enters the rollers, and the gap between the rollers is adjusted by a precision control system to control the thickness of the solidified material. The gap between the rollers gradually decreases as the glass fiber cloth enters the rollers and exits the roller nip zone, that is, the gap between the upper and lower rollers decreases from large to small, and the gap between the last pair of rollers 31 is 0.1 to 0.3 mm; as a result, the thickness T of the glass fiber cloth after roller pressing and solidification is 0.1 to 0.3 mm.
[0041] Step 4, the rolled glass fiber cloth 1 is automatically wound into shape by a winding mechanism 4;
[0042] Step 5, cooling the wound coil;
[0043] The cooling temperature is 10-30°C.
[0044] Step 6: Spray glue on the cooled coiled material to obtain a finished winding material.
[0045] Through the above continuous manufacturing process, the forming production of winding materials is realized. After the glass fiber cloth is impregnated with epoxy resin, it is rolled and wound at high temperature to form a roll of material. The roll is then coated with wire body spray glue to achieve the finished roll effect. The entire process is simplified, the production steps are reduced, the production efficiency is improved, and the winding production of materials is realized, and the needs of mass production and processing are met.
[0046] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
