Application of Magnesium Hydroxide/Diphenoxy Phosphate in Silicone Rubber Flame Retardant Cable Material

نویسندگان

چکیده

Deketoxime–type room–temperature vulcanized silicone rubber cable materials were prepared using α, ω–dihydroxy polydimethylsiloxane, carbon black, calcium carbonate, magnesium hydroxide, piperazine bis (diphenoxy phosphate) salt (PBDP), and melamine diphenoxy phosphate (MDP). The effects of black flame retardants on the mechanical properties, flame–retardant electrical insulation properties coatings investigated. research results showed that products obtained had good with tensile strength greater than 3.0 MPa, dielectric 22 kV/mm, volume resistivity higher 6.5 × 1014 Ω·cm. When 30 parts Mg(OH)2:MDP = 2:1 are added to 100 resin, performance wire can be significantly improved. Under thermal radiation illumination 50 kW/m2, ignition time (TTI) Mg(OH)2/MDP coating increased by 16 s, maximum heat release rate (pkHRR) total (THR) decreased 29.7% 68.8%, respectively, compared without retardant. retardant up FV–1 level.

Performance of Flame Retardant Wool Fabric Grafted with Vinyl Phosphate

In this paper, a flame retardant dimethyl-2-(methacryloyloxyethyl) phosphate (DMMEP) was applied to wool fabrics by the graft copolymerization technique initiated with potassium persulfate (KPS) in water media. FTIR and SEM testing were used to explore the grafting evidence on the fiber surface, the SEM results show chemical deposition on the wool fiber surface and the scales could not be seen ...

British Columbia Hydromagnesite-Magnesite Resources: Potential Flame Retardant Material

Hydromagnesite occurrences in British Columbia have been recognized since the beginning of the 19th century (Reinecke, 1920; Young, 1915). However, the known occurrences of hydromagnesite are too small to compete with the large sparry magnesite deposits in British Columbia (Grant, 1987; Simandl et al., 1996 a,b and Simandl, 2000) as potential sources of raw materials for the production of indus...

Natural Rubber/Dendrimer Modified Montmorillonite Nanocomposites: Mechanical and Flame-Retardant Properties

A series of flame-retardant nanocomposites were established based on compounding of natural rubber (NR) and dendrimer modified flame-retardant organic montmorillonite (FR-DOMt). The merits of these nanocomposites were focused on their better mechanical and flame-retardant properties. X-ray diffractometer (XRD) together with scanning electron microscopy (SEM) and transmission electron microscopy...
