Epoxy glue is also known as epoxy resin and epoxy resin glue. Because of its low price compared with other similar products, it has various forms of application. The form of epoxy glue is a transparent liquid, and it needs to be mixed with AB to cure it. , The cured product has the characteristics of water resistance, chemical resistance, crystal clear and so on.
Epoxy adhesive is formulated with polyurethane prepolymer modified epoxy resin (component A) and self-made curing agent (component B) in a ratio of 10:1 to 1:1 (weight ratio) to be resistant to high temperature and good toughness. , Reactive curing system. Among them, the polyurethane prepolymer is a hydroxyl-terminated polysiloxane and a diisocyanate reacted in a certain proportion under certain conditions to prepare an isocyanate group-terminated polysiloxane polyurethane prepolymer, and then the epoxy resin is treated with this polyurethane prepolymer. Modified. The self-made curing agent is composed of diamine, imidazole compound, silane coupling agent, inorganic filler and catalyst.

On August 6, the U.S. stock market fell sharply, and both the Dow Jones index and the Nasdaq index hit new lows. On August 10, the Tokyo stock market also showed a general downward trend. The most important reason for this is the general rise in crude oil prices. As a result, major manufacturers are watching the development and promotion of hybrid vehicles. With the recent rise in the price of crude oil, automakers have finally waited until the best time for the introduction of a new type of fuel-efficient vehicle-hybrid hybrid. Last week, Ford announced that its automotive plant in Kansas will mass produce the world's newest gasoline- and electricity-powered SUVs. This shows that Ford Motor Company has started to aggressively attack the hybrid vehicle market. GM also said it will launch hybrid Chevrolet and GMC later this year. Following this trend, Honda plans to officially launch a new hybrid car, the Accord Hybrid, at the end of this year. Toyota Motor Corp., which hopes to strengthen its leading position in the field of gasoline and electric hybrid vehicle technology, has also recently claimed that it will increase the production of hybrid vehicles to 300,000 next year. In the US market, Toyota launched the hybrids Insight and Civic in 1999 and 2002. Toyota also announced in 2002 that it will use gasoline-electric engines (hybrid engines) on all Toyota-built cars from 2012 onwards. The United States Federal Government also established a free car project as early as 2001 to promote the research and development of hybrid vehicles. The three major automakers in the United States have each produced HEV prototypes to demonstrate the applicability of this technology. In addition to using hybrid power in the small car segment, GM plans to launch two light hybrid trucks in 2007. Daimler-Chrysler will also produce similar environmentally-friendly heavy-duty truck DodgeRam in the fall of 2004. It is reported that comprehensive plans announced by major auto makers will allow up to 15 hybrid vehicles to be launched in North America in the next three years. This kind of car seems to have prepared a large number of North American markets. All manufacturers are rushing to introduce new hybrid vehicles, which undoubtedly indicates the arrival of a high demand in the market. Hybrid vehicles can not only significantly improve the fuel economy, but also significantly reduce greenhouse gas and air pollution emissions. Compared with other eco-friendly electric vehicles, hybrid vehicles are superior in that they still use traditional gasoline or diesel fuel, and do not need to establish new infrastructure (such as gas stations). The car has two power systems, one is a gasoline engine and the other is an electric motor. It converts each other according to the speed of the vehicle at the time of work to save fuel. Toyota's "PRIUS" is the world's first mass-produced first-generation hybrid sedan in 1997. Last year, it carried out a brand-new improvement, pursuing the world's highest standards of high efficiency, low fuel consumption, and low exhaust emissions. The charm of driving. In China, more and more attention is paid to the development prospects of hybrid vehicles. It is reported that the government has made reducing the exhaust emissions of automobiles and limiting the increasing energy consumption as the top priority of the work. Due to rising energy demand and rapid increase in vehicle ownership, China has become the second largest emitter of greenhouse gases in the world. Experts predict that by 2030, China will surpass the United States and become the world’s largest emitter of greenhouse gases. Greenhouse gas is considered to be the culprit of global warming. The world's major auto giants are therefore very optimistic about the Chinese market. Once the Chinese government has issued approval procedures for such vehicles, they will immediately launch hybrid vehicles into the Chinese market. According to foreign reports, U.S. General Motors and Shanghai General Motors are studying the market feasibility of launching hybrid cars in China. According to a U.S. GM official who understands this issue, if the plan is really implemented, this hybrid car will be a small SUV. Takeshi Uchiyamada, senior managing director of Toyota Motors, recently stated that in order to increase the possibility of selling hybrid vehicles in China, Toyota and the China Automotive Technology and Research Center have jointly conducted a research activity on hybrid vehicles. To help the latter understand this technology more fully. The China Automotive Technology and Research Center is responsible for formulating exhaust emissions, fuel quality, and energy efficiency standards for the government. Experts predict that in the near future, hybrid vehicles will become the major models in the automotive market. Reporter Ye Linsheng
