The focus of global flame retardant research is: halogen-free flame retardants, halogen-free anti-flame retardants, halogen-free phosphorus-free metallic oxide flame retardants; flame retardant resin composition focused on copper plate and electronic packaging; flame retardant thermostate resin / thermoplastic resin composite materials become a new research hot spot. In particular, polysilica oxide as a halogen-free, phosphorus-free, metal-free oxide of the new flame retardant has been the attention of colleagues around the world, self-flame retardant silicone coatings have become a hot spot for marine coatings, cyanate as flame retardant, heat-resistant materials become a research hot spot, polysalt ether as a high temperature, flame retardant material has become a new material for industrialization. The flame retardant of thermostate resin has become a hot spot in the study, in which the study of essential flame retardant resin focuses from the thermoplastic resin to thermosolytic resin, while in the field of thermostic resin, epoxy resin becomes one of the key points. In addition to the new halogen-free flame retardant copper plate, environmentally friendly electronic chemicals and electronic components, epoxy resin flame retardant research is mainly distributed in five areas.
first is the electronic insulator and the immersion welding photosensitive composition. Toshiba Chemical's Hanamura, Kenichiro, etc. have developed halogen-free photosensitive epoxy resin components for electronic insulators or solder-resistant applications that can be used in mezzanine insulators for immersion-resistant solder or printed circuit boards, including epoxy acrylics, epoxy resins, thinners, curing agents, photosensitive agents, 2-50 servings of 9,10-Bihydrogen-9-oxygen hybrid-10-oxyphosphate-10,10-(2,5-hydroxybenzene)-10-hydrogen-9-oxygen-hybrid-10-oxycodone-10 or its derivatives and inorger fillers, the composition has good bonding, heat, moisture and refraoric resistance. The second is the low-release flame retardant curing. NEC company Iji Masatoshi applied for a U.S. patent entitled "Retardant thermostate epoxy resin composition", which has a small environmental impact, high flame retardant thermostate epoxy resin composition consists of two essential components: epoxy mixture containing benzene-based crystalline energy group, phenolic compound. For example, in a composition, epoxy equivalent 170, softening point 104 degrees C epoxy resin 21.2% and 9.8% hydroxyl equivalent of 106, softening point of 80 degrees C phenol-formaldehyde resin, its weight average molecular weight of 1200, Tg104 degrees C, oxygen demand 37.1%, with good release and solidification properties.
3rd is the epoxy flame retardant curing agent. Phosphorus epoxy flame retardant curing agent has become a hot research topic in the world today, a variety of phosphorus-containing curing agents have been successfully applied to epoxy resin composite materials, especially laminated materials. Several new phosphorus-containing curing agents have been synthesized with phosphorus-containing curing agents with phosphorus content between 3 and 15%, and the flame retardant resistance of epoxy resins can be improved by curing human epoxy resins. The fourth is the modified ABS of 6 bromine flame retardant epoxy. Bar-Yaakov of Israel Bromide Compounds Co., Ltd. studied flame retardants, flame retardant resin components and their preparation, wherein the flame retardant compound is halogenated epoxy resin, the compound can be brominated epoxy resin, its epoxy group is at least partially inline by brominated HPPMAE. For example, F-2200 brominated epoxy resins are treated with a mixture consisting mainly of a mixture of TBPA-monomedehye and catalyst to obtain a modified bromine epoxy resin (epoxy equivalent 13107g/equivalent). Molded ABS resins containing the above modified bromine epoxy (21.8%) and other components have a notch impact strength of 29.3 J/m and a thermal decomposition temperature of 70.4 degrees C (using ordinary epoxy flame retardants (F-2016) with data of 16.1 J/m and 69.7 degrees C, respectively).
flame retardant effects of nitrogen, phosphorus and molybdenum are the fifth aspect. Bhuniva, Sankar, of the Materials Science Centre of the Indian Institute of Technology, studied the flame retardant properties of nitrogen and phosphorus-based polymers, as well as the effects of nitrogen and palladium on their flame retardant properties, and synthesized phosphorus- and heterocyclic epoxy resins with better flame retardant effects and better thermal stability than existing standard biphenol A-epoxy propane, and reported the effects of nitrogen and vanadium on phosphorus-based and heterocyclic epoxy resins. Synergies are greatest at a particular P/N or radon/N scale. In short, halogen-free flame retardant, halogen-free anti-phosphate metallic oxide flame retardant, flame retardant resin composition focused on copper plate and electronic packaging, flame retardant thermostate resin / thermoplastic resin composite material has become a new research hot spot. Epoxy resin as a base material flame retardant material in this field has great advantages, will certainly get high and widespread attention outside the industry, the formation of a new flame retardant industry, running thermostate resin flame retardant technology progress.。
