Asphalt flame retardant in the market can be divided into several
Many people have already realized the greater effect of asphalt flame retardants in preventing combustion. They feel that this is a very important flame retardant raw material. The following flame retardant experts want to tell you what kind of flame retardant can be divided.
The first, halogen flame retardant solvent
This kind of flame retardant solvent is mainly bromine flame retardant solvent, the effect of preventing combustion is very outstanding, but when preventing combustion, it will release a lot of toxic gases, some of which will produce some cancer substances when burning, and the cost of investment is relatively high.
Second, nitrogen and phosphorus flame retardant solvent
This kind of asphalt flame retardant will produce strong dehydration solvent when heated at high temperature, so that the surface of asphalt will be dehydrated and carbonized, which can isolate the combustible gas and heat outside and inhibit the spread of combustion. At the same time, it will decompose to produce ammonia and water vapor when heated. The former is mainly to dilute the concentration of oxygen element in the air, which has better combustion prevention effect. In addition, the thermal stability is relatively high and the water solubility is relatively poor, low smoke and toxins, economic use, is an ideal flame retardant solvent.
Third, non-halogen composite type flame retardant solvent
When this solvent is burned, it will release bound water and absorb a lot of heat, thereby inhibiting combustion. The bound water will produce an oxidation reaction with carbon substances at a higher temperature, and at the same time reduce the appearance of flue gas, so as to prevent combustion and The dual effect of suppressing flue gas.
