The plastic USES microcapsule flame retardant
Plastic is widely used in industry, agriculture and daily life, but nearly all of the plastic is easy to burn, and some of them also when burnt plastic produces a large number of harmful gas and smoke, so fire resistant and flame retardant plastics is an important problem. In the case of plastic flame retardant technology, it is commonly used to add plastic microcapsules to flame retardants. According to rough statistics, about 65% of the global flame retardants are used in flame retardant plastics.
The application of microencapsulation technology in flame retardant is a new technology circle developed in recent years. Microcapsules are also called microspheres, which are tiny containers that wrap solid particles or droplets of liquid in a natural or synthetic polymer material. The diameter of a capsule is generally 1, 000 bym. The leather membrane used in plastic use of microcapsule is called wall material, and the material of the bag is called core material.
When used, the preparation of microcapsule by mixed with polymer materials or other materials, to be applied on the base of heat, pressure or radiation means break the microcapsule, release the package material, produce the desired application performance, or does not destroy the cyst membrane, the package material to the outside through cyst membrane diffusion release, control performance.
Plastic with microcapsule flame retardant advantage lies in the formation of microcapsule, capsule heart was enshrouded and environmental isolation with the outside world, it has no influence to the properties of being preserved, and under appropriate conditions, the wall was damaged when the capsule
The heart is released, which brings many conveniences to the use.
The microencapsulation technology of flame retardant can be improved from the following aspects.
A) gas and liquid flame retardant have become solid flame retardant after microencapsulation.
B) according to the types of flame retardant materials required for choosing the appropriate capsule material, stretching only few after the capsule material, fire retardant and people increase the compatibility with polymer, so as to reduce and eliminate flame retardant adverse impacts on the physical and mechanical properties of polymer products.
Triisobutyl Phosphate (TIBP)
The product output: 200 tons / month
Shipping Port: China Shang Hai
Price offer is valid: 15 days
Jincang time: 15 days (commodity inspection)
Export rights: the right to import and export company.
Triisobutyl Phosphate(TIBP) is mainly used for antifoamer and penetrant. It is also be widely used in printing and dying, ink, construction, and oil field additives, etc. Another chemical name of Triisobutyl Phosphate (TIBP) is tri -butyl phosphate.
C) can reduce the migration of liquid flame retardants in polymer materials and the loss of flame retardants in polymer materials due to the volatilization of liquids.
D) reduce the amount of toxic components in the process of polymer processing and avoid environmental pollution.
E) can block the pungent smell of the flame retardant and change its color.
F) the density and volume of flame retardants can be changed.
Phosphorus and phosphorus compounds is the most important type of flame retardant, red phosphorus sources because of its wide, non-volatile, low price, and the advantages of good flame retardant effect, used as a flame retardant has more than 30 years of history, it is a high priority of flame retardants.
Compared with other type adding phosphorus-containing flame retardant, high phosphorus content of red phosphorus, therefore, to achieve the same level of flame retardant, red phosphorus add volume less than other flame retardants, flame retardant polymer with it has good physical and mechanical properties, so its dosage increased year by year and has good prospects for development.
But itself with color of red phosphorus, easy oxidation, poor stability, moisture absorption into acid with dust explosion hazard, used for thermoplastic processing generated when extremely toxic PH: problems, is limited as the main cause of flame retardants are widely used. If red phosphorus microencapsulation, these problems can be solved. As a result, Mr. O 'yuxiang predicted in his article that the microencapsulated red phosphorus was one of the most promising halogen flame retardants in the first 10 years of the 21st century.
Simple phosphorus is a flammable substance, but in resin, red phosphorus and other phosphorus-containing additives are not simply oxidized. Phosphorous additives mainly work in condensed phases, and the flame retardant mechanism is:
The first step: to form phosphoric acid distribution as dehydrating agent and promote carbon, and the formation of carbon reduces the heat conduction from flame to coagulation phase.
Step 2: phosphoric acid can absorb heat, because it prevents CO oxidation as CO2 and reduces the heating process.
Step 3: to form a thin layer of vitreous condensed phases or liquid layer, thus reducing the oxygen diffusion of heat and mass transfer between the gas phase solid phase, suppresses the carbon oxidation process, reduce the phosphorus flame retardant thermal decomposition.
