The development prospect of epoxy resin combined with curing agent is broad

Epoxy resin is odorless, tasteless, alkali resistant, and resistant to most solvents. Has excellent adhesion to metals and non metals. Good heat resistance, insulation, hardness, and flexibility. Can be used as an adhesive for metal and non-metal materials (such as ceramics, glass, wood, etc.) (with strong adhesion, commonly known as universal glue). It can also be used to manufacture coatings, enhance plastics, or cast into insulating components. And it can be used to treat imitation fabrics, playing a role in anti wrinkle, anti shrinkage, water resistance, etc. Low molecular weight epoxy resin can be used as a stabilizer for polyvinyl chloride.

Currently, China is the world's largest consumer of epoxy resin. Data shows that in 2011, the global consumption of epoxy resin was 2.2 million tons, with China's consumption reaching 900000 tons; By the end of the 12th Five Year Plan, global consumption will reach 3 million tons, with China's consumption exceeding 1.75 million tons, accounting for 58% of the global total. Over the years, the production capacity of epoxy resin in China has made significant progress. Currently, the total installed capacity has far exceeded 1.75 million tons. With the addition of new production capacity in the next three years, by the end of the 12th Five Year Plan period, China's epoxy resin production capacity will be available for global consumption.

In recent years, the rapid development of the epoxy resin industry has been matched with the rise of China's manufacturing industry. However, like many rapidly developing industries, the problem of lightweight in the early stages also exists in the epoxy resin industry; That is to say, when ordinary basic products develop to a certain stage, the market's demand for mass products begins to become saturated, and the demand for special high-end epoxy resin products is increasing. As a result, the period of industrial restructuring naturally arrives.

When the production capacity of an industry develops to a certain stage, coupled with the progress of technological innovation, the distribution of product application fields will undergo fundamental changes. The epoxy resin industry is an example. From continuously expanding the application scope to adjusting the industrial layout, it is inevitable. Currently, optimizing quality and variety has become a new task facing the epoxy resin industry.

What is the new task? This is the rapid development of China's epoxy resin industry, but the pace of development of its supporting assimilates seems slow. Because the assimilation agent and epoxy resin have a symbiotic relationship, epoxy resin only has practical value after assimilation, and the consumption of curing agent is basically equivalent to about 35% of the consumption of epoxy resin. However, due to its high research cost, complex synthesis technology, and diverse application methods, the global curing agent market has always been dominated by a few developed countries such as Europe and America. Among them, the higher quality assimilation agent variety - i-yuan synthetic amine, the profit margin of foreign production giants even exceeded 80% at one point. Many industry insiders believe that during the rapid growth of China's epoxy resin industry, the main profits used to go to foreign companies, but this situation is currently changing.

It is gratifying that according to the current development trend, in the next few years, there will be a fundamental change in the in-house production and supply rate of basic amines and some binary and binary polymerization curing agents. The main reason is that since 2010, with the continuous efforts of industry insiders, domestic self created technology and introduced joint venture technology have been produced simultaneously. Currently, products have been launched, breaking the monopoly of foreign production of epoxy curing agent basic amine Fb and providing initial relief.

Another important event was the 2012 Epoxy Resin Industry Development Forum held in Suzhou in late October, which focused on the development direction and modification technology of curing agents in the key supporting industry of epoxy resin. The forum aimed to accelerate the coordinated development of the epoxy resin industry and solve the problem of advanced production capacity and insufficient demand in the domestic epoxy resin industry, which became the focus of attention for the attending representatives. The attending experts delved into the application field of epoxy resin and listed six major development directions for curing agents:

One is functional curing agent. Due to the limited progress in developing new structures and high-performance epoxy resins to meet resin modification requirements, curing agents with special functions will become the darling of the market. Compared with traditional curing agents, functional curing agents usually have excellent properties such as rapid curing, low-temperature curing, toughening, and flame retardancy.

The second is low toxicity and non-toxic curing agent. At present, the industry not only focuses on the toxicity and environmental pollution issues during the production and use of curing agents, but also attaches great importance to the long-term pollution problem of waste epoxy resin products. It is reported that in developed countries, highly toxic polyene adhesives and aromatic amines have all been replaced by non-toxic or low toxicity modified amines. It is a curing agent that can adapt to special environments. For example, curing agents that maintain good and stable performance in humid, underwater, and harsh outdoor environments.

Thirdly, curing agents with excellent electrical, mechanical, and mechanical properties will be greatly developed.

Fourthly, electron beam and photopolymerization products are receiving increasing attention.

With the popularity of environmentally friendly products, the prospects for powder coatings, water-based epoxy resin coating curing agents, and single component adhesive assimilators are broad.

Yang Xianyi, Secretary General of the China Epoxy Resin Industry Association, believes that accelerating the coordinated development of the epoxy resin industry is urgent. On the premise of complying with environmental and safety regulations and meeting user needs, continuously reducing costs and developing towards serialization, specialization, matching, and refinement are the long-term tasks of assimilation agent production enterprises. At the same time, he suggested that in order to accelerate the coordinated and healthy development of the epoxy resin industry, epoxy resin and curing agent production plants should form partnerships and promote each other, which is an effective way for the entire industry to succeed.
