Curing agents, also known as hardeners, are essential components of many polymer systems, including Epoxy Resins. Curing agents react with the epoxy resin to form a three-dimensional crosslinked network, resulting in a cured polymer with improved mechanical properties, chemical resistance, and thermal stability.

Another innovative safety technology was born in the passenger car industry, and it is expected to greatly reduce road traffic safety accidents caused by fatigue driving. The author was informed that the lane departure warning system (LDWS, LaneDepartureWarningSystem) pioneered by Daikin Dragon was selected on its full-range road passenger car from July 12th, which also meant that the Chinese passenger car entered a new era of active safety.
The lane departure warning system is an active safety device that makes an alarm reminder reaction to the situation where the vehicle abnormally deviates from the current driving lane by capturing and calculating the relative relationship between the vehicle and the road marking line. The system can provide intelligent lane departure warning. When the driver unconsciously (does not make a turn signal) deviates from the original lane, he can give an alert before the vehicle deviates from the lane, providing more response time for the driver and greatly reducing the risk of lane departure. Collision accident.
In the world, road traffic accidents cause astonishing casualties and economic losses. According to statistics, about 44% of auto accidents are related to vehicles deviating from normal lanes. The main reason for this is the driver's inattention and fatigue driving, causing unconscious deviation of the vehicle. Therefore, installing a lane departure warning system on a vehicle will help reduce road safety accidents and protect the safety of passengers.
Dajinlong New Science and Technology Research and Development Department has taken the lead in developing the lane departure warning system independent research and development in 2010. With the support of Xiamen's key production, research and development projects, the project has undergone long-term road tests, algorithm verification, and mold development. Finally at the end of June this year, the company officially entered volume production.
The main features of the Dajinlong lane departure warning system include: smart camera, LDWS controller, and LDWS rocker switch. With optional vibration cushions, various warning methods such as sound and vibration of lane departure warning can be realized. In order to make the system work properly, the vehicle must be equipped with Dragon Wing System (KL-988 Jinlong Onboard Computer Information System). The main purpose is to receive vehicle operating parameters (vehicle speed, steering, brake signals, etc.) through the wing system to effectively reduce false alarms. rate.
Dr. Xiaoqi Xiao of Dajinlong New Technology Research and Development Department introduced that the development of the lane departure warning system has experienced nearly 3 years. The project team has done a lot of road testing and performance comparison work to ensure the reliability and stability of the product. The system has stable and reliable detection accuracy in various road environments. Recently, the appraisal team composed of industry experts agreed that the performance of Dajinlong’s lane departure warning system has reached the leading level of similar products at home and abroad.
Dr. Chen Xiaobing said that in addition to the lane departure warning system, Daikin Dragon will also launch active safety technologies such as night vision imaging, smart reversing trajectory, and forward anti-collision alarm system. Daikin Dragon adheres to the idea of ​​independent design and integration innovation in the development strategy of passenger car safety technology. There are no profitable considerations for the development of a series of key parts and components, and it can ensure that passenger transport uses the latest scientific and technological achievements at a lower cost. Effectively improve the safety of Chinese passenger cars.
There are several types of curing agents, each with its own unique properties and applications. The most common type is amine-based curing agents, which react with the epoxy functional group to form a secondary amine and an alcohol. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications.
Another type of curing agent is anhydride-based, which react with the epoxy group to form a cyclic acid anhydride and a hydroxyl group. These curing agents are typically used in applications where water resistance is critical, such as marine coatings and adhesives.
Other types of curing agents include phenolic, acid, and catalytic curing agents. Phenolic curing agents are used in high-temperature applications, while acid curing agents are used in low-temperature applications. Catalytic curing agents are used to accelerate the curing process and are typically used in combination with other curing agents.
The choice of curing agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured polymer. It is important to choose the correct curing agent to ensure that the final product meets the desired specifications.
In summary, curing agents are essential components of many polymer systems, including epoxy resins, and play a critical role in improving the mechanical, chemical, and thermal properties of the cured polymer. The choice of curing agent depends on the specific application requirements and must be carefully considered to ensure the final product meets the desired specifications.
