Flame retardant for epoxy resin material

Flame retardant for epoxy resin material

The consumption of the flame retardant of epoxy resin has grown rapidly and the new flame retardant of new epoxy resin has been springing up. The research on the flame retardant technology of epoxy resin was investigated. The results show that the current development trend of epoxy resin flame retardant technology is safe, compound functionalization, new technology and systematic research.

In order to make epoxy resin material flame retardant material not harmful to the human body and environment in the preparation process, the first requirement is that the flame retardant itself is non-toxic. Second requirement in the process of the flame retardant high temperature decomposition product is nontoxic, non irritant, smoke quantity very less time.

Some common flame retardants (e.g., phosphorus-containing flame retardant), because of the large amount of smoke and the smoke, gas released the toxic ingredients in the corrosive environment object, make the person suffocate, causing more larger secondary disasters. In order to reduce harmful effects of flame retardant for has the use safety of flame retardants, to smoke suppression, no poison, no halide flame retardant epoxy resin as the theme of safety has become a main trend of technology development and application.

When studying the flame retardant performance of epoxy resin, the basic requirement is not to damage its original performance, such as not reducing its mechanical properties and electrical properties. With the development of the flame retardant technology of epoxy resin, on top of these basic requirements, it is also hoped that the epoxy resin has certain functions.

For example, in order to solve the A1 (OH) 3 in appliance with wet resistance of epoxy resin system problem, is to improve the electrical insulation in wet or humid environment, will be mixed with Al (OH) 3 in Na ion control under 100 mu g/g can achieve a goal. Use the microparticle A1(OH)3 and treat it with stearic acid.

Or the flame retardant epoxy system can be improved by the treatment of silicone, such as epoxy silane and ethylene silane. In addition, the requirements and has function of flame retardant and antistatic and flame retardant and electromagnetic wave shielding effect function of epoxy resin products. Under some special conditions of use, also with heat and radiation resistant epoxy resin flame retardant materials. All in all. The trend of multi-level composite function has been developed for flame retardant epoxy.

In order to develop and perfect the flame retardant technology of epoxy resin, many emerging technologies have also begun to apply to the research on the flame retardant properties of epoxy resin. For example, in order to make the aluminum hydroxide, magnesium hydroxide, antimony oxide and other inorganic flame retardants can more effectively use, require the use of new technology of powder engineering of particulates, also available surface chemical technology makes the reasonable particle size grading. And effectively control the shape of particles and increase their affinity with epoxy resin.

Flame retardant TPP has many advantages, such as excellent transparency, softness, bacterial resistance, and water proof, grease-proof, good electric insulation, as well as good compatibility. Flame retardant TPP is mainly used as the flame-retardant plasticizer for cellulose resin, vinyl resin, natural rubber and synthetic rubber. And it may also be used as the flame-retardant plasticizer for glyceryl triacetate thin ester and film, rigid polyurethane foam, phenolic aldehyde resin, and PPO, etc.

Flame retardant TPP is a kind of halogen-free environment-friendly flame retardant with phosphorus element. Most of the products in the market are self-colored flaky crystal, our product is self-colored crystalline powder, and is more soluble in organic solvents. TPP is not soluble in water, but soluble in benzene, chloroform, ether and acetone, and slightly soluble in Z alcohol. Flame retardant TPP is nonflammable with slight aromatic odor and slight deliquescence. The fusion point is about 50 ℃, and fast melts to hoop-shape when heated. The lubricate effect is excellent, and it is often used as the flame retardant plasticize lubricant. What is more, it is used as the flame retardant for many plastics and resins, such as phenolic aldehyde resin, epoxy resin and so on.


Microcapsule technology also have started to use in the use of flame retardant, it can help more effectively play the role of flame retardants in epoxy resin system. In foreign countries, the flame retardant epoxy resin flame retardant microcapsule has become a frontier research hot topic. In order to reach the goal of flame retardant, must have a precise characterization of various performance analysis test method.

There are all kinds of modern precision instrument analysis methods in the basic data of physics and chemistry. But the accuracy of the test method to represent the flame retardant performance is not enough. We should continuously improve the analysis and testing methods of flame retardant performance. To this end, in addition to the attention of human operation technology, in the test of each link, try to adopt the instrument of automatic control. Connect with the computer. It is necessary to modernize the test technology.

TGA, DSC thermal analysis methods, such as epoxy resin has gradually been institute using flame retardant performance, given by the properties of flame retardant epoxy resin in other research institute, now given in other technical areas to the thermal analysis method and chromatography, spectral method of combination of the stage, the study of flame retardant epoxy resin technology should also be comprehensive use of various analysis methods to illustrate some fundamental problems.

Flame retardant epoxy resin system is a complex system of various components, including flame retardants, carbonized accelerators, coupling agents and crosslinking agents, anti-smoking agents and fillers. Obviously, such a complex system can not be fully guided by a few empirical rules and general scientific principles.

For the comprehensive performance of the system optimization, it is necessary to investigate the interaction between these components to play a role of the gain between them, avoid harmful between them, the action of offset each other. In concrete application process, not only to achieve the balance of the amount of chemical theory, also must study the kinetics of thermal decomposition process of these components, namely in the different time, temperature of them basically in a state of equilibrium, starting from the processing stage, until the high-temperature pyrolysis, and must rely on many experiments to attain the best formula. Therefore, the study of flame retardant epoxy resin system technology can not only stay on for the study of the structrue of flame retardant additives, curing agent, flame retardant, also from the point of view of comprehensive, systematic study.
