Embodiment Construction
[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0023] refer to figure 1 , figure 2 As shown, a device that can prevent acrylate adhesive from gelling includes a glue storage device 2, a glue output control part 4, a glue flow rate control part 5, and a high-voltage electric field processing part 6. The glue storage device 2 is supported by the feet 3, and one end of the bottom is provided with a glue outlet 21, and the bottom is inclined along the direction of the glue outlet, so that the glue can flow out of the glue storage device 2 smoothly.
[0024] The glue outlet 21 of the glue storage device 2 is provided with a glue quantity control unit 4, which is composed of a rubber baffle 41, an adjusting rod 45, and a fixing bolt 46. The rotation of the adjustment rod through the circular handle 44 can drive the gear 43 arranged on the adjustment rod to rotate, and the gear 43 ca...

The invention discloses a device for preventing an acrylate adhesive from gelating. The device comprises a high-voltage electric field treatment part positioned on an adhesive flowing plate. The high-voltage electric field treatment part is composed of a fixed plate, an electric field plate, a field distance adjustment part and guide rods. The electric field plate is arranged below the fixed plate. The field distance adjustment part is directly connected to the electric field plate through a hole disposed at the middle part of the fixed plate, and the distance between the electric field plate and an adhesive flow upper surface can be controlled by adjusting the field distance adjustment part. The guide rods control the directional stability of the electric field plate, which can directly act on the acrylate adhesive flowing on the adhesive flowing plate through a KV-KV high-voltage uniform electric field. By means of a physical treatment method, the microstructure of the acrylate adhesive body can have delicate change so as to prevent the occurrence of gelating. Thus, the device provides guarantee for the adhesive utilization rate and adhesive tape yield.
Description
technical field [0001] The invention relates to an adhesive processing device, in particular to a device capable of preventing acrylic adhesive from gelling. Background technique [0002] Acrylate adhesives have the advantages of fast curing speed, high bonding strength, large temperature span, good water, acid, oil and alkali resistance, and long storage time. , medical, aviation, construction, telecommunications equipment and other industries. [0003] In the process of making adhesive tapes, hardeners (usually isocyanate-based, metal chelate-based, epoxy resin-based) and organic solvents (usually isopropanol or toluene) must be added to the finished acrylate adhesive to fully Stir it, then apply it on the film, and dry it in an oven to make a semi-finished tape. The semi-finished tape is then matured at a certain temperature to make the hardener and glue fully react and cross-link, so as to make a finished tape. [0004] In this process, if the curing agent is added to ...
