Embodiment 2
[0044]Embodiment 2, insert the primer process between step 2 and step 3 in the above embodiment 1 to form this embodiment, for the shell made of SMC, after the alcohol is volatilized and dried on the shell, use the primer Apply the paint pen evenly for a week along the position where the sealing strip needs to be installed on the housing, and let it dry. The primer material is specifically TEROSON SB 450.
[0045] Specifically, after the primer coating process is completed, it is naturally dried at an ambient temperature of 18-25° C. for 10-180 minutes.
[0046] By applying primer material on the sealing flange surface of the SMC housing, it can ensure that the silicone sealing strip is bonded to the position where the sealing strip needs to be installed on the housing, avoiding falling off during transportation and installation, which will affect the sealing effect.
[0047] The invention also discloses a silicone sealing strip production line, such as image 3 As shown, th...

Abstract
The invention discloses a silica gel sealing strip production process. The silica gel sealing strip production process comprises the steps that 1, in-place inspection is conducted, specifically, the appearance of a shell is inspected, oil stain pollution is avoided, and clashing, scratching and deformation are avoided; 2, cleaning is conducted, specifically, cotton cloth or tissue paper is dippedin alcohol, the position, where a sealing strip needs to be mounted, of the shell is wiped, and no dirt exists; 3, gluing is conducted, specifically, continuous gluing is conducted along the position,where the sealing strip needs to be mounted, of the shell, glue discharging is uniform, and the whole circle of foamed silica gel sealing strip is formed; 4, drying is conducted, specifically, the shell with the foamed silica gel sealing strip is integrally dried; and 5, detection is conducted, specifically, the section size and the position size of the foamed silica gel sealing strip are inspected, and that the appearance is compact and free of roughness is inspected. According to the silica gel sealing strip production process, the whole circle of foamed silica gel sealing strip is formed by directly conducting gluing on the shell, the production efficiency is improved, the material and labor cost is reduced, and the sealing quality is ensured. The invention further discloses a silica gel sealing strip production line used in the process.
Description
technical field [0001] The invention relates to the technical field of production of silica gel sealing strips, in particular to a production process of silica gel sealing strips and a production line thereof. Background technique [0002] With the increasing tension of conventional petrochemical energy and the enhancement of people's awareness of environmental protection, new energy vehicles have been developed by leaps and bounds. The battery and key circuit control components in new energy vehicles need to be placed in a moisture-proof and waterproof casing, and the sealing of the casing requires the use of sealing strips. The casing sealing strips in the prior art often use foamed silica gel strips, which are die-cut and then spliced and bonded in segments along the sealing contour of the casing to form a full-circle sealing strip. The foamed silicone strip requires 50% compression and a rebound of not less than 95% after ten years. [0003] However, the processing m...
