Flame Retardant Treatment Method of Flame Retardant in Building Materials

Flame Retardant Treatment Method of Flame Retardant in Building Materials

In building materials, most of the building plastics are combustible materials, and a small number of them are flame retardant materials. Plastic in the fire several combustion heat, high temperature artillery, burning speed, the release of a large number of smoke and toxic gases, therefore, building plastics must be flame retardant characteristics, professional flame retardant manufacturers, for you to introduce, flame retardant treatment methods in building materials. 1, add flame retardant in the plastic to add flame retardant and inorganic filler, so that the combustion characteristics of plastic products to be good. Commonly used inorganic flame retardants are aluminum hydroxide, magnesium hydroxide, magnesium carbonate, zinc borate, = two zinc oxide; organic flame retardants are chlorinated paraffin, hexabromobenzene,

Magnesium hydroxide in the high-end flame retardant market continues to be optimistic

Magnesium hydroxide in the high-end flame retardant market continues to be optimistic

Magnesium hydroxide is a new type of filled flame retardant, in the process of thermal decomposition of the release of combined water, absorb a large amount of latent heat, in order to reduce the surface temperature of the filling of synthetic materials in the flame, with the inhibition of polymer decomposition and the effect of the production of combustible gas cooling. The magnesium oxide generated by the thermal decomposition of magnesium hydroxide is an ideal refractory material. In addition to helping to optimize the fire resistance of the synthetic material, the water vapor released by the decomposition also has the effect of smoke suppression. Therefore, in the rubber industry, magnesium hydroxide is recognized as a high-quality flame retardant with three functions of smoke suppression, filling and flame retardant. At present, in the field of communication cable

Widespread application of magnesium hydroxide in various industries

Widespread application of magnesium hydroxide in various industries

Dilute acid is also ammonium salt solution. Magnesium hydroxide is a kind of alkaline substance, which can be used as analytical reagent and pharmaceutical engineering industry. Magnesium hydroxide is also used in various aspects. Let's take a look at the efficacy and function of magnesium hydroxide. 1. Magnesium hydroxide is widely used in environmental protection, because magnesium hydroxide can be used as a neutralizing agent, it is alkaline, and because of its good adsorption, it can be used to deal with acid-containing waste, as well as some wastewater treatment, containing heavy metals and organic waste water treatment can use magnesium hydroxide. 2. Magnesium hydroxide is also used to prevent combustion, it is a flame retardant, because hydrogen and oxygen

What are the developments in the application of PP flame retardants?

What are the developments in the application of PP flame retardants?

Halogen-antimony system, namely gas phase flame retardant mechanism. Commonly used halogen flame retardants are decabromodiphenyl ether, hexabromocyclododecane, octabromo ether, tetrabromobisphenol A, etc., plus flame retardant synergistic agent antimony trioxide, with a small amount of addition, good flame retardant effect. PP is treated with a bromoalkyl-containing phosphate ester. This kind of flame retardant has P-Br synergistic effect, so that the flame retardant effect is significant, but also can improve the rheology and processing performance of PP, the physical and mechanical properties of PP is also small. In recent years, in PP flame retardant technology, the intumescent flame retardant pioneered by Camino, a professor at the University of Turin, Italy, has played a huge role.

What are the reasons for the failure of flame retardants after use?

What are the reasons for the failure of flame retardants after use?

Flame retardant is a kind of flammable polymer flame retardant functional additives, can be widely used in fabric, wood, plastic, rubber, polyurethane and other aspects of flame retardant, sometimes in the use of flame retardant when flame retardant material failure, then the use of flame retardant material failure reasons. 1. Different flame retardants. Different flame retardants have different flame retardant effects, such as the failure time of disposable flame retardants and durable flame retardants. The flame retardant effect and failure time of water-based flame retardant and flame retardant varnish are different, and the resistance of wood treated with flame retardant varnish is obvious.

Current Market Status of Flame Retardants

Current Market Status of Flame Retardants

Flame retardants are common additives used to prevent or reduce the possibility of burning combustibles, and the current status of the flame retardant market is as follows. 1. Inorganic flame retardants such as magnesium hydroxide and aluminum hydroxide are not only cheap and green environmental protection products, but also have low flame retardant efficiency and require high addition amount to make the material flame retardant. Moreover, inorganic flame retardants have poor compatibility and affinity, thus greatly reducing the impact resistance of the material or losing the flexibility of the material. Therefore, they are often used in occasions with low requirements on the mechanical properties of the material. 2. Inorganic flame retardants like antimony trioxide, zinc borate, etc. are also often used as flame retardant

What is the role of aluminum hydroxide in flame retardants?

What is the role of aluminum hydroxide in flame retardants?

Aluminum hydroxide and aluminum metahydroxide collective, aluminum chloride monohydrate. In order to improve the penalty properties of Al(OH)2 as a flame retardant, improve heat resistance, moisture resistance, low smoke, and flame retardant substrate compatibility and electrical insulation, a lot of research has been carried out, such as the grain size of ultra-fine particles, particle shape and reasonable control and reasonable size surface distribution. Treatment with a coupling agent to minimize the Al(OH)2Al content. The new brand of American Andi Company halofree halogen-free, low smoke, low toxicity, non-corrosive and thermal stability, flame retardant, based on modified Al(OH)2: inorganic flame retardant,

What conditions should flame retardants be used in foam plastics?

What conditions should flame retardants be used in foam plastics?

With the gradual expansion of the scope of application of rigid polyurethane foam, there are higher requirements for the performance of foam, in which flame retardant is the most important problem. Rigid polyurethane foam is widely used in refrigerator, freezer box insulation layer, cold storage, refrigerated trucks and other insulation materials, buildings, storage tanks and pipeline insulation materials, its most fundamental disadvantage is flammable. Now and flame retardant manufacturers together to understand the application of flame retardants in the foam plastic should have what conditions? 1, the performance of the foam plastic effect is small; 2, the amount of small and good effect; 3, flame retardant
