Key technology of magnesium hydroxide flame retardant
The research on the key technology of magnesium hydroxide flame retardant has been made. Recently, Chinese academy of sciences institute of qinghai salt lake magnesium hydroxide flame retardant project team, to adopt new convert agent system with ordinary magnesium hydroxide as raw material, through hydrothermal modification complete crystal shape of flame retardant type magnesium hydroxide is six Angle of flake.
At the same time they are in industrial test flame retardant type magnesium hydroxide is the key technology in the process of amplification, economic indexes have reached the international advanced level, to provide the magnesium hydroxide flame retardant industrialization capacity design basis. The industrial grade hydroxide material is not completely satisfied with the requirements of domestic and foreign customers due to its large size and wide distribution.
Qinghai salt lake research institute of Chinese academy of sciences researchers in science and technology, Chinese academy of sciences, China green projects and the support of the department of qinghai province, to improve the process condition for synthesis of magnesium hydroxide, high purity and ultrafine magnesium hydroxide was successfully synthesized, preparation of the desired particle size index of magnesium hydroxide flame retardant is hexagonal flake.
They in the annual output of 2000 tons scale experiment device of the key technologies of industrial magnesium hydroxide flame retardant and the enlarge test unit equipment, completed the flame retardant grade magnesium hydroxide industrial test key technology development, the unit equipment magnification and the process conditions were determined and rationalization of correlation between process and optimize the process operating conditions, solve the flame retardant type magnesium hydroxide is industrialized production, the key technology of the particle size distribution.
Currently, the flame retardant is mainly bromine, and bromine flame retardant is a large family in flame retardant, with more than 70 members. Bromine is widely found in nature, especially in seawater, saltwater lakes and soil. Production and application of bromine series flame retardant with a long history, production technology and application technology is mature, widely used in electronics, electrical products, not only effectively reduce the incidence of fire of electrical and electronic products and and good stability, even after years of use is still in line with the new fire safety standards, the more valuable is the material recycling process, still can maintain a good stability. Bromine flame retardants are believed to affect the environment, and most bromine products have been banned by the eu's "two orders".

Diphenyl Isooctyl Phosphate (S141,362, DPOP) Product Overview
Chemical Classification: Diphenyl Isooctyl Phosphate, Diphenyl 2-Ethylhexyl Phosphate
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Is An Excellent Flame Retardant Plasticizer That Can Be Used In Most Industrial Polymers Including PVC And Its Copolymers, Nitrocellulose, Ethylcellulose, Poly Methyl Cellulose Methyl Ester, Polystyrene And The Like. Diphenyl Isooctyl Phosphate (S141,362, DPOP) Are Generally Used In The Manufacture Of Vinyl Sheets, Coated Fabrics, Inks, Plastics, Rubber And Plastic Foamed Organic Sol, Adhesives, Vinyl And Conveyor Belts. Due To Excellent Solubility, Improve The Performance Of Many Formulations. In Addition, It Can Be The Final Product It Offers The Following Range Of Interesting Properties Such As Flame Retardancy, Low Temperature Flexibility, Abrasion Resistance, Grease Resistance, Excellent Light Stability And Outdoor Weather Resistance And Excellent High Screen Welding Performance. Due To Its Excellent Solubility, Diphenyl Isooctyl Phosphate (S141, 362, DPOP), And Then 3 Phr Of Bismuth Oxide And 10-20 Phr Of Aluminum Hydroxide Were Added.
Diphenyl Isooctyl Phosphate (S141,362, DPOP) Can Be Used As An Excellent Flame Retardant Material For Transparent Films. In Some Fire-Resistant Harsh Colored Films, It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To Significantly Improve The Light Stability And Outdoor Weather Resistance Of The Film.
(S141,362, DPOP) With Diphenyl Phosphate And Tricresyl Phosphate In The Presence Of 10-15% Of Phthalate Plasticizer Such As DOP, Phosphoric Acid Diphenyl Isooctyl Ester (S141, 362, DPOP) Allows The Resulting Plastic To Have A Low Initial Viscosity And A Good Good False Plasticity And Storage Stability. Due To Its Good Pseudoplasticity And Film-Forming Properties It Is Recommended To Add Diphenyl Isooctyl Phosphate (S141,362, DPOP) To PMMA-Based Plastics And Nitrocellulose Coatings And Inks.
Mechanism of flame retardant of magnesium hydroxide as fire retardant are: magnesium hydroxide thermal decomposition of the water, at the same time to absorb a large number of latent heat, thus inhibiting polymer temperature rise, extending its thermal decomposition and combustion rate reduction, this reduces the resin in the fire of the actual temperature, can inhibit polymer decomposition and cooling effect of flammable gases. Natural magnesium oxide after decomposition is good refractory material, cut off the oxygen supply and stop the activities of the combustible gas, help progress resin flame resistance ability, and the thermal decomposition temperature of magnesium hydroxide as high as 340 ℃, so the flame retardant magnesium hydroxide as fire retardant performance is very superior.
Magnesium hydroxide can have a thicker oxide layer when filled with medium filling. Carbonized layer of natural, blocking the heat and oxygen in and out of the combustible gas escape, dewater diluted, endothermic cooling can play a bigger role, adding magnesium hydroxide reduces the initial decomposition temperature of oxidation. And become larger with the increase of the amount of loss. In addition, the natural magnesium oxide is used to make fine refractory materials to cover the surface of high polymer. It also can improve the ability of the polymer to resist the flame.
With other two kinds of inorganic flame retardants than calcium carbonate and aluminum hydroxide, magnesium hydroxide is of small precombustion area and the burning area, but occur in the degradation of the solid flame retardant effect is significantly more than the calcium carbonate and aluminum hydroxide on the smoke elimination effect is also very obvious. Magnesium hydroxide as a non-toxic fire retardant agents, can be used for polypropylene, polyethylene, PVC, epdm, and unsaturated polyester polymer flame retardant smoke elimination. Especially suitable for high processing temperature of polyolefin plastics.
Magnesium hydroxide is an additive inorganic flame retardant, which has better anti-smoking effect than similar inorganic flame retardants. As 80% of the fires are smothered by smoke, it is more important that the modern flame retardant technique is more important than "flame retardant".
Magnesium hydroxide is an environmentally friendly green flame retardant in the process of production, use and waste without harmful substances and can neutralize the acidic and corrosive gases produced during combustion.
