Inorganic additive environmental flame retardant
Department of magnesium hydroxide flame retardant inorganic additive environmental protection flame retardant, flame retardant, smoke abatement, resistance drop, filling, such as multiple performance, compared with the aluminum hydroxide, has high thermal stability, efficient effect on promoting substrate into carbon and strong capacity in addition to the acid properties, magnesium hydroxide flame retardant has the following advantages:
1. Safe and non-toxic. The flame retardants themselves are not toxic and produce no toxic gases. It is both a flame retardant and a smoke inhibitor.
2. Good physical properties. Although the filling quantity is large, it does not reduce the rigidity, heat resistance and impact resistance.
3. Good forming and filling quantity is large, but the forming performance is good, and the rear cover of large TV sets is also easy to form.
4. Good intersolubility of polymers, no seepage and sublimation of organic flame retardants.
5. The combination of flame retardant and flame retardant is functional filler.
6, magnesium hydroxide thermal decomposition temperature of 330 ℃, 100 ℃ higher than the aluminum hydroxide and therefore beneficial to the improvement of the plastic processing temperature, extrusion speed, shorten the molding time.
7. Magnesium hydroxide has a strong ability to suppress smoke and small hardness, which can help to extend the life of production equipment.
Based on the above characteristics, in today's global increasingly strict environmental requirements, inorganic additive environmental protection flame retardant magnesium hydroxide in polypropylene, polyethylene, PVC, epdm (epdm) and unsaturated polyester paint and coatings, and other polymer materials have been widely used in flame retardant masterbatch, flame retardant cable, adhesive tape products, interior decoration materials, belt transmission, etc are made gratifying achievements, and is expanding its new USES.
Tert Benzyl diphenyl phosphate (BPDP-71B) basic information
Chinese name t - butyl phthalate diphenyl phosphate
(1,1-dimethylethyl) phenyl diphenyl phosphate; t-butylbenzene diphenyl phosphate (MDPP); tert-butylated triphenyl phosphate 71B)
English name tert-Butylphenyl diphenyl phosphate
English name: Tert-Butylphenyl Diphenyl Phosphate; T-BUTYLPHENYL DIPHENYL PHOSPHATE; Phosphoric Acid (1,1-Dimethylethyl) PhenylDiphenylEster; Arylphosphates; Tetrabutylphenyldiphenylphosphate; BPDP; PARA-TERT-BUTYLPHENYLDIPHENYLPHOSPHATE; Tert.-Butylphenyldiphenylphosphate
Molecular formula: C22H23O4P
Molecular weight 382.39
EINECS 260-391-0
Tert Benzyl diphenyl phosphate (BPDP-71B) use
Tert-butyl phosphate diphenyl phosphate, tert-butylated triphenyl phosphate is halogen-free organophosphorus flame retardant, using a new, excellent performance of phosphorus flame retardant, with excellent thermal stability and hydrolysis Sex. Its high thermal stability makes it as an engineering plastic flame retardant at the same time, can improve the plastic melting performance. Tert-butylated triphenyl phosphate for the liquid, in the resin can make its durability and hydrolysis stability is better, and easy to produce the table and stress cracking. It is widely used in flame retardant PV (, cellulose resin, into the rubber, phenolic resin, epoxy resin, polyene unit fiber.
As in 100, benzene latex, 53 samples add magnesium hydroxide and aluminum hydroxide respectively, burning not only of the magnesium hydroxide flame retardant effect is good, and make the material the ability to smoke less than aluminum hydroxide is outstanding, in polyolefin and - polyolefin, respectively, adding appropriate amount of magnesium hydroxide and aluminum hydroxide, magnesium hydroxide to add 100, relative to add 100 aluminum hydroxide oxygen index not only bigger, and the tensile strength, elongation rate is high. The original performance of polypropylene can be basically maintained with 100-200phr high filling.
Inorganic additive is commonly used in environmental protection flame retardant of magnesium hydroxide filled polypropylene its tensile strength, impact strength than polypropylene is poor, however, through the modification of the magnesium hydroxide flame retardant is room temperature impact strength and better than that of the polypropylene makings, it shows on the morphology of magnesium hydroxide, especially in the selection of surface treatment technology, surface agent on still has great and worth studying.
A lot of research and practice prove that magnesium hydroxide particles, the smaller the dispersion and uniformity among polymer materials is higher, the flame retardant performance is better, and high filling quantity for material can be processed performance impact will be small. Superfine grade magnesium hydroxide (more than 5000 mesh) even if the use of high fill, also does not dramatically affect the physical properties of their products, such as modified by the right, will have a more ideal result.
Magnesium hydroxide must be used as a flame retardant
1. High purity must be obtained, and the water loss rate shall not be less than 30% (600 degrees can be calcined in a high temperature furnace);
2. Must have hexagon or needle microstructure (microscopic observation);
3. It has to have extremely fine grain size (above 5000 eyes) and the distribution of laser particle size is even, because the particle size is more than that of the general assembly as the stress concentration point in the composite material, which becomes the weak link of the material;
4. Sufficient surface modification must be carried out to make it hydrophobic (which can be tested in water).
