GLPOLY is developing the ceramicized multi-functional heat insulation and thermal conductivity structural adhesive XK-CD06L, which belongs to the patented advanced material, can withstand high temperature above 1200 degrees, both can be ceramicized, service heat insulation, runaway adiabatic function. Different thermal conductivity from the same series of ceramicized multi-functional heat insulation and thermal conductivity structural adhesive XK-CD12L (1.2W/mK), but also has insulation, super structural strength, sealing function. It is mainly used for the thermal runaway management between the cell and cell and between the cell and top cover of CTP, CTC, CTB type power battery. When the battery encounters the extreme situation of fire, it can instantly ceramicize, play the role of heat insulation and fire prevention, strive for the escape time of the occupants, minimize casualties, is the guardian expert in the field of power battery performance safety .
GLPOLY's independently developed and produced vitrified multi-functional thermal conductive structural adhesive XK-CD06L belongs to modified epoxy system, with thermal conductivity of 0.6W, and has the function of vitrified when encountering extreme high temperature. In fact, as early as August, the vitrified multi-functional thermal conductive structural adhesive XK-CD12L has been applied to the thermal conductive bonding of the battery top cover, which has passed the verification and severe endurance test of the top European OEMs' multiple mounting modules and officially started the delivery of the mass production order of the battery pack. Subsequently, we were asked to provide a thermal insulation bonding solution between the battery cells, which also needs to be resistant to temperatures above 1000 degrees. From XK-CD12L to XK-CD06L, the earliest request for this technology was made by an European head car manufacturer, based on the supply cooperation with GLPOLY's modified epoxy thermal conductive structural adhesive previously purchased, which met the needs of mass production models and the safety requirements of new energy vehicles. In view of the frequent power battery safety accidents in new energy vehicles and the safety anxiety of users, this global top car manufacturer never stops pursuing high performance safety materials, and in early 2021, through the battery factory to Jinling Tongda's R & D department: in the case of taking into account the high bonding insulation performance, extreme high temperature thermal runaway such as the extreme case of temperature greater than 1000 degrees, when the battery fire, how to maximize the protect the lives of the occupants? According to the actual application of customers, Jinling Tongda's R & D team designed and optimized the whole process of technology exchange, automated dispensing path, with follow-up customer package verification test, after nearly a year of hard work, in the first half of 2022 finally successfully completed the modified epoxy system based on D series thermal conductive structural adhesive to ceramic multifunctional thermal insulation and thermal conductive structural adhesive XK-C12L to ceramic multifunctional thermal conductive structural adhesive XK-C12L. XK-CD06L series products. At the same time, all the test reports and third-party inspection reports of XK-CD06 were completed simultaneously and the samples were successfully delivered to the customer's European laboratory. So far, we have successfully developed this ceramicized multi-functional thermal insulation and thermal conductive structural adhesive XK-CD06L, which fully meets the customer's application requirements and also shows the R&D strength of Jinling Tongda team.
XK-CD06L is a ceramicized multi-functional heat insulation and thermal conductivity structural adhesive based on modified softened epoxy resin, which is especially suitable for heat insulation bonding between electric cores and is suitable for new energy vehicles, energy storage and rail transportation. Whether in terms of bonding insulation performance or durability, the polyurethane structural adhesives on the market are not comparable, and the long-term reliable service life of Jinling Tongda's ceramicized multi-functional heat insulation and thermal conductivity structural adhesive is more than 25 years.
The samples of XK-CD06L ceramicized multi-functional heat insulation and thermal conductivity structural adhesive were sent to Europe, and a series of tests including destructive tests were carried out in the customer's laboratory to verify its excellent physical, chemical and electrical properties in line with the specification:
1. porcelain forming temperature is less than 450°, fast porcelain forming speed.
2. Bonding strength greater than 8MPa, can withstand a 120km/h disaster impact, 12m free fall, the battery does not short circuit, no fire.
3. Breakdown voltage resistance is more than 10kV/mm, typical value can be as high as 25kV/mm.
4. Flame retardant grade is higher than UL94- V0, extinguishable when away from fire.
5. Suitable for dispensing process, in line with the automated factory mass production, while the R & D engineering team to provide a full range of technical support dispensing path design services.
GLPOLY XK-CD06L ceramicized multi-functional thermal insulation and thermal conductivity structural adhesive is the top core material to fully improve the functionality and safety of power battery. It is suitable for thermal insulation, insulation and super sealing bonding of various power battery service conditions, and for thermal runaway condition, it is suitable for refractory insulation and protection of neighboring metal plates from melting to avoid melt-through accidents. Under the extreme conditions of thermal runaway, XK-CD06L is unique in the industry with its super insulation and fireproof performance to protect life safety. It is no exaggeration to say that the competitors can only look up to it when it comes to efficiently solving the safety anxiety of power batteries. Jinling Tongda, the safety guardian expert in the field of new energy vehicle power batteries, is the leader in the countermeasures and material solutions for high-grade thermal conductivity materials.
