Improvement of nitrogen and phosphorus expansion flame retardant
With the continuous development of flame retardant polymer material processing technology, the requirements of the comprehensive performance index of flame retardants of the higher, high efficiency, good compatibility, high thermal stability will be the future development direction of flame retardants, nitrogen and phosphorus in the future expansion type flame retardant should be improved in the following five aspects:
The improvement direction of nitrogen and phosphorus expansive flame retardant (1) has high thermal stability and meets the need of polymer high temperature processing and forming. APP and PER thermal stability is not high, especially the production APP has strong hygroscopicity, because components in many small molecule compounds, lead to thermal stability is bad, not suitable for high temperature engineering plastics.
The surface treatment of flame retardant of nitrogen and phosphorus expansion flame retardant is improved. With nitrogen and phosphorus coupling agent processing expansion type flame retardant in order to increase the compatibility with polymer, to improve nitrogen and phosphorus dispersion of expansion type flame retardant in the matrix, and at the same time obtain good flame retardant properties and mechanical properties.
The commonly used coupling agent is silane coupling agent, titanate coupling agent and so on. In addition, using microcapsule technology processing package of nitrogen and phosphorus expansion type flame retardant is treated, can improve the moisture resistance of nitrogen and phosphorus expansion type flame retardant, improve the nitrogen and phosphorus expansion type flame retardant and the compatibility of the matrix, thus achieve the goal of improve the flame retardant material performance.
The improvement direction of nitrogen and phosphorus expansive flame retardant (3) was treated with micro-refining. Larger nitrogen and phosphorus expansion type flame retardant particles can damage the physical and mechanical properties of materials, expansion of nitrogen and phosphorus flame retardant agent ultra-micronization model.the, nano, even can not only increase the nitrogen and phosphorus expansion type flame retardant and the contact area in order to improve the compatibility of materials, and can reduce the amount of nitrogen and phosphorus expansion type flame retardant.
The synergistic effect of nitrogen and phosphorus expansive flame retardants (4). The addition of nitrogen and phosphorus expansive flame retardant is relatively large, and the flame retardant efficiency is not high, so it is limited to a certain extent. If the study found that the polyolefins of the flame retardant of nitrogen and phosphorus were found, the LOI reached more than 30% when the dosage was 20%~ 30%. Therefore, selecting the appropriate coefficent and increasing the flame retardant efficiency of nitrogen and phosphorus expansion flame retardants can reduce the cost of flame retardant materials and create greater economic benefits for enterprises.
In the direction of improvement of nitrogen and phosphorus expansive flame retardant (5), a new type of flame retardant with low moisture absorption, high thermal stability and high flame retardant effect is developed.
Trimethyl phosphate (TMP)
Cas No:512-56-1
HS Code HS: 29199000
The most important indicator of product: colorless transparent liquid,colorless transparent liquid Content ≥ 99.5%, moisture ≤ 0.2, the acid value ≤ 0.02, Chroma ≤ 20
Raw materials: phosphorus oxychloride reacted with methanol in the presence of potassium carbonate to produce phosphoric acid trimethyl ester.
Belong to several categories of dangerous goods: Currently Trimethyl phosphate (TMP) general cargo exports are not dangerous.
Trimethyl phosphate (TMP) use is mainly used in medicine, pesticides, solvents and extractants, used as a solvent, extraction, determination of zirconium and GC stationary liquid, the ester is used in medicine and pesticide solvent and extractant. Pesticide intermediates. In Japan, Trimethyl phosphate use as anti stain of textile oil and polymer, flame retardant additive for lithium ion battery.
Trimethyl phosphate is currently the main market in India, mostly for textile auxiliaries, the products are mainly exported to Japan, South Korea, Thailand, India.
As of Trimethyl phosphate use need to do not understand, please contact us!
The moisture absorption problem and dispersion of nitrogen and phosphorus expansive flame retardant have always been a concern. It is often necessary to modify the nitrogen and phosphorus expansive flame retardants, and the modified treatment methods are modified with surface modification and microcapsules.
Surface modification. Surface modification is to point to by physical, chemical and mechanical methods powder expansion type flame retardant particles surface processing, so as to change the physical and chemical properties on the surface of the flame retardant, meet the needs of the plastics flame retardant materials.
RavaditsI studied the surface of the application/PER flame retardant PP material treated with organic borosilicate (OBSi), and got the nitrogen and phosphorus expansive flame retardant/OBSi flame retardant system, and the effect of the treated flame retardant system was significantly improved.
Microencapsulation treatment. Microencapsulation refers to the application of a coating film or shell material to apply the small solid particles, droplets or bubbles. Microcapsules containing solid particles are basically the same shape as those in the capsules, while microcapsules containing liquids or gases are generally shaped like spheres. In the case of filler flame retardant, the essence is to cover a layer of homogeneous and thick film on the surface of the particle, thus increasing the surface modification method of the flame retardant efficiency by adding the packing dispersion.
Using microcapsule technology for package of expansion type flame retardant modification, which can improve the moisture absorption of expansion type flame retardant, prevent effective flame retardant composition in flame retardant system migration, further improve the expansion type flame retardant and the compatibility of the matrix, thus achieve the goal of improve the flame retardant material performance.
