The researcher development of 2 worlds university gives the family in Naples cost heart one kind has the whole live thing that enhances agglutinate performance base epoxy resin, provided a kind of substitute that can last to be based on the colophony of double phenolic A. Because epoxy resin of double phenolic A may cause healthy problem, because this has particular demand to environmental protection substitute.

Compare with traditional colophony photograph, epoxy resin shows biology radical taller ultimate meet an emergency, slightly quantity of model of low vitrification transition temperature, drawing and ultimate strength. Additionally the most notable is, it shows lubricious adhesive strength in juncture place, the congener product tower above than be based on BPA 3 times. This one development is high-powered be at war agent application offerred the solution that can last, satisfy safety and the effect that pair of environments reduce while the technology asks. Relevant research achievement is published in " material science magazine " on.
Furan radical epoxy resin
The furan that comes from carbohydrate base epoxy resin already made the oil that is used at adhesive application base the has an outlook substitute of the recipe. 2, 5- double [(annulus oxygen ethane - oxygen of 2- radical armour base) methylic] furan (BOMF) is derive one kind from 5- hydroxide methylic furfural (the compound of HMF) , it is one of the most important elements that produce from carbohydrate. In the research previously, the epoxy resin that BOMF derives already was used at agglutinate polycarbonate base material, show compare the drawing shear strength with higher aether of glycerine of shrink of petrifaction radical phenyl.
One of newest progress of this domain include to pass acid anhydride of use Ma Lai (MA) solidify BOMF develops complete biology base epoxy resin system. MA is extracted very easily from inside HMF, make its make choice of a kind of environmental protection. Use difference shows scanning to measure hot way (DSC) changes with chemistry shedding the analysis monitors cross-linking process, evaluate earning epoxy resin to enhance hot solid sex in carbon fiber (the agglutinate function on CFRP) connect.
Biology radical the advantage of epoxy resin
Compare with the traditional epoxy resin photograph that is based on BPA, BOMF/MA shows multinomial advantage. It shows taller ultimate strain, slightly quantity of model of low vitrification transition temperature, drawing and ultimate strength. In addition, BOMF/MA shows outstanding adhesive strength on CFRP connect, give 3 times than be based on the corresponding object height of BPA. This kind of extraordinary adhesive strength highlighted furan radical epoxy resin regards structural adhesive as the latent capacity in each industries.
In addition, the development of epoxy resin solved biology radical these material can be challenged duratively in production. Replace double phenolic A through using biology radical substitute, researcher is safer, more the adhesive of environmental protection applies and try hard, defend the heat in composite material of coating, shipbuilding originallies for example sexual matrix, wind- driven turbine and plane and structural adhesive.
Apply actually and did not study
As increase ceaselessly with the demand of environmental protection material to can lasting, biology radical the actual application of epoxy resin is very wide. Mix to the building from car and aviation industry but industry of second birth energy, these epoxy resin can offer high-powered adhesive solution, reduce the integral effect to the environment at the same time. In addition, biology radical of epoxy resin but rework sex is more absorbing also, come from oil of annulus oxidation vegetable and garment for example the colophony of hot solid sex of health acid.
Although development has the whole live thing that enhances agglutinate performance base epoxy resin is a significant progress, but the character that still needs to consider to improve these data in order to continue further and function. Through exploring the new combination of biology radical compound and solidify agent, scientists can be developed for all trades and professions more effective, more the adhesive of environmental protection, make contribution for the future that can last more.
