Development Trend of Epoxy Coating Crosslinking Agent
Epoxy coating cross-linking agent development trend in the development of high-quality, high functionality, serialization, specialization of cross-linking agent.
Development trend of epoxy cross - linking agent: development of new varieties of cross - linking agent
(1) the new varieties of amine is still the first place, followed by acid anhydride;
(2) containing / semi-inorganic polymer 0 crosslinker containing P, Si, B, F, Mg and other elements;
(3) a modified thiol type and a modified phenol-based crosslinking agent;
(4) a new block copolymer having a thiol group at its terminal.
From the cross-linking agent development direction, there have been six major trends
(1) functional cross-linking agent to become the focus of future research and development. Versatility (with cross-linking, toughening, fire-retardant, and other functions) cross-linking agent to become the ideal product. Due to the development of new structure and excellent performance of the epoxy resin progress is not large, so as to adapt to the resin modification requirements of functional additives to become the focus of research and development, more than one more products.
Rapid cross-linking, low temperature crosslinking and the lowest water absorption of the rapid development of cross-linking agent. Special function of the cross-linking agent has also been greatly developed, such as elastic cross-linking agent.
(2) cross-linking agent low toxicity, non-toxic. Modern people not only concerned about the cross-linking agent in the production and use of the process of toxicity and environmental pollution problems, but also attach importance to waste epoxy resin products, environmental pollution problems. In developed countries, primary polyene polyamines and aromatic amines have all been replaced by non-toxic or low-toxic modified amines.
(3) to meet the special environment (wet, underwater, outdoor, etc.) use of cross-linking agent popular.
Chinese name: Diethyl toluene diamine(DETDA)
Physical and chemical properties: light yellow transparent liquid, slightly soluble in water, soluble in alcohols, ethers, ketones and other polar organic solvents, and polyether, polyester polyol compatibility.
Density 1.022
Viscosity (20 ℃) ??mPa·ss290±10
Pour Point ℃-9
Boiling point of310°C

(4) To meet the high performance requirements of epoxy resin, electrical properties, excellent mechanical properties of the cross-linking agent will be vigorously developed.
(5) electron beam and light cross-linked cross-linking agent more and more people's attention.
(6) powder coating special cross-linking agent, water-based epoxy resin coating water-soluble cross-linking agent and single-component adhesive special cross-linking agent and other promising.
From the manufacturing technology, the following trends
(1) the application of modified technology is increasingly widespread.
(2) complex efficiency and assembly technology in the ascendant. Environmental protection regulations, cost, energy saving and other factors, the new structure of the cross-linking agent development more difficult, through the complex container to improve efficiency has become an effective way to develop new cross-linking agent.
(3) solid cross-linking agent liquid technology is very promising, such as solid-state acid anhydride at room temperature, dicyandiamide and other modified by its liquid at room temperature, not only can improve its operation and performance, but also save energy.
(4) cross-linking agent production operations and packaging refinement.
Crosslinking agents are fine and special chemicals, the development of cross-linking agent must pay attention to scientific research, vigorously develop new varieties, and the use of existing chemical structure of the cross-linking agent, the use of chemical, physical modification and other methods to improve its performance, In order to ensure the sustained and stable development of China's epoxy resin industry.
Organic hydrazide is a high melting point solid, mixed with epoxy resin storage period of up to 4 months, reduce the temperature required for accelerator and dicyandiamide similar. Lewis acid amine complex is another effective latent cross-linking agent, which is the most studied boron trifluoride amine complex, Xu Xiaoming and other new synthetic compounds such as good performance.
