The characteristics of flame retardant wood materials are as follows
The combustion process of flame retardant wood materials has low smoke production and low toxicity
The flame retardant itself is non-toxic and does not pollute the environment in the process of production and use
Durable and stable flame retardancy
Low hygroscopicity does not affect the dimensional stability of wood materials;
The processing performance and service performance of wood materials are not changed;
It has anti-corrosion and anti insect properties.
1. Research and development of smoke suppression and flame retardant
70-75% of the deaths in fire are caused by smoke poisoning.
According to GB8624, the smoke production additional grades of building materials and products are divided into S1, S2 and S3. At present, the additional grade of smoke production of most of the flame retardant wood materials is S2
| Smoke generation rate index
|| Total flue gas generation
2. Development of flame retardant with low smoke toxicity
The addition of p-n flame retardant changed the combustion state of wood materials, and the formation of harmful substances such as CO, HCN, NOx, VOCs and particulate matter increased by 3-100 times compared with ordinary wood
According to GB8624, the smoke production additional grades of building materials and products are divided into three grades: T0, T1 and T2.
Grade T1 is the basic requirement, but some flame retardant wood materials do not meet this requirement.
3. Intumescent flame retardant
The intumescent flame retardant system can reduce the influence of flame retardant on the processing and performance of materials
At present, high score is applied in the field of material processing
It is urgent to solve the problem of high cost in the field of wood materials.
4. Surface modification of flame retardant
P-n, p-n-b and p-n-al are still the main flame retardants in the production of flame-retardant wood materials.
Through surface modification, the compatibility of flame retardant with wood material and resin is improved, the influence of flame retardant on the processability and usability of wood material is reduced, and the production cost is further reduced.
Invention patent: zl201010219578.8 a flame retardant and its preparation method
Research and development of multifunctional flame retardant
The wood protective agent with many functions, such as flame retardant, smoke suppression, antisepsis, mildew proof and improving the dimensional stability of wood materials, will become an important development direction of wood flame retardant.
