High heat resistance coating crosslinking agent
This paper introduces the research situation of high heat resistance coating crosslinking agent of epoxy resin.
In the field of heat crosslinking technology, several functional couplets with high heat resistance, flame retardancy and toughness are emphasized, and several new kinds of modified amines cross linking agents are introduced. The microwave crosslinking system of epoxy resin was analyzed and discussed in this paper. In the field of optical cross-linking technology, the progress of the cationic ultraviolet cross linking system and free radical - anion hybrid optical cross linking system is reviewed.
Epoxy resin can be used as adhesives, casting material, glass steel and coatings. Its good performance such as adhesion, electrical insulation, chemical resistance, high strength, high heat-resistant ability, and all kinds of new product development, make it in the fields such as machinery, aerospace, electrical, chemical application is more and more widely.
In order to further improve the performance of the epoxy resin crosslinking, it can be used to modify resin matrix or synthetic resin. At the same time, it can also start from additives to achieve its high - sexual energy. Research and use of new crosslinking techniques is also becoming a major approach.
As for the work of research and its modified epoxy matrix gradually thorough, the epoxy resin crosslinking technology made greater progress, all kinds of special performance of the new crosslinking agent, epoxy resin at home and abroad in recent years has become a general application research hot spot. Flame retardant and high heat resistance coupler. The flame retardant performance of epoxy resin can be realized by the physical mixing of flame retardant additives, but the additive is easy to lose and the process is complicated. By means of chemical bond, the flame retardant material is connected to the polymer skeleton structure, and it not only realizes the permanent adhesion of the flame retardant group to the resin, but also has little influence on its physical and mechanical properties.

Diethyltoluenediamine packingļ¼ net weight 200KG/ galvanized iron drum (a small cabinet pallet loaded 16 tons), 1000KG/IB barrels (a small cabinet loaded 18 tons or 23 tons of ISOTANK).
Compared with traditional brominated flame retardants, organophosphorus compounds produce less toxic substances while showing high performance of high performance flame retardancy. Shieh et al. used the reaction of o-phenol and phosphoryl chloride to make phosphorous compounds ODC, and the new phosphorous flame retarded crosslinking agent OD p-pn was synthesized by ODC and linear phenolic resin (PN).
Sexual intercourse with high heat resistant agent crosslinked epoxy resin, because of its internal contain ODC neat structure and phosphorus side group, the crosslinking agent than acyclic phosphorus or bromine and crosslinker crosslinked epoxy resin has higher flame retardant performance, higher glass transition temperature and thermal stability. In this case, the CNE, which is crosslinked with the crosslinking agent, can reach the ul94-vo standard when the phosphorus content is 1.21%. (if brominated crosslinking agent is used, the bromine content should reach 6%), and no toxic smoke is released. When phosphorus content is 1.72%, the LOI value (the minimum percentage of oxygen in the mixture of oxygen and nitrogen that supports the combustion of a substance) can reach 35.
The successful F series epoxy resin crosslinking agent is the modified phenolic resin, which has been commercialized. The crosslinking agent can make the general high temperature resistance of epoxy resin 300 and 300 degrees Celsius, with a clean and safe high flame retardant performance and outstanding ablation resistance, its crosslinking content even at high temperature decomposition of residual carbon layer are still part of the performance of raw materials.
F crosslinking agent itself is free of pollution and can be stored for a long period of time. It is easy to construct, which can be used in powder and in solution. It can be both high temperature fixation and medium temperature crosslinking, and has the function of natural color, which is a multi-purpose high-efficiency crosslinking agent. F - 52B and f-52a cross-linking agent f-52b and f-52a respectively crosslinked e-51 epoxy resin and multifunctional epoxy resin afg-90 thermogravimetric analysis (TG) curve and differential thermogravimetric curve (DTG).
After crosslinking of E - 51 epoxy resin decomposition temperature is 380 degrees Celsius, maximum weight loss rate in 405 degrees Celsius, 467 degrees c and then slowly began to weightlessness and 800 degrees Celsius when quality remains rate 38.17%; The decomposed temperature of the multi-functional epoxy resin AFG - 90 is lower than that of e-51 epoxy resin, but its quality retention rate above 800 degrees can reach up to 50%. The quality retention rate is close to zero at 600 ~ 700 c.
