Combining example 3 and comparative examples 1-7 and table 2, it can be seen that, on the basis of comparative example 7, only one or two of light calcium carbonate, tricarballylic acid and succinic acid are added, compared with the addition of light calcium carbonate, tricarballylic acid and succinic acid in example 3, the smoke reduction effect and flame retardant property are inferior, the reason is that, during the production process, tricarballylic acid is melted and mixed with light calcium carbonate and succinic acid uniformly, during the fire, light calcium carbonate reacts with tricarballylic acid and succinic acid during the combustion process to generate water and carbon dioxide, and the generated water not only can play the role of auxiliary fire extinguishing together with carbon dioxide, but also can be combined with the smoke generated by the combustion, thereby reducing the smoke dissipated to the surrounding environment and reducing the pollution to the environment; and the light calcium carbonate reacts with the tricarballylic acid and the succinic acid to generate corresponding calcium salt, so that the heat conductivity of the flame-retardant material is improved, and the flame retardance of the flame-retardant material is effectively improved.
By combining example 3, comparative example 8 and comparative example 9 with table 2, it can be seen that the generation of toxic smoke is effectively reduced by using the inorganic flame retardant as the flame retardant component, thereby effectively reducing the pollution of the halogen flame retardant to the environment during combustion; compared with the adoption of an organic flame retardant, in the production process, the tricarballylic acid reacts with part of aluminum hydroxide and magnesium hydroxide to generate corresponding aluminum salt and magnesium salt, so that the heat conductivity of the flame-retardant material is improved, and the flame retardant property of the flame-retardant material is effectively improved.
It can be seen from the combination of example 3 and examples 7-14 and from Table 2 that the flame retardant property of the flame retardant material is effectively improved by the selection of the addition amount of aluminum hydroxide and magnesium hydroxide.
It can be seen by combining examples 3 and 15-22 and table 2 that the flame retardant property of the flame retardant material is effectively improved by selecting the addition amounts of fumed silica and zirconia, the hydrophilic fumed silica and zirconia form a protective layer, and the water generated during the combustion process is combined with the hydrophilic fumed silica, so that the flame retardant effect can be achieved, and the generated smoke can be combined with the hydrophilic fumed silica, thereby further improving the flame retardant property of the material.
Combining example 3 with examples 23-30 and table 2, it can be seen that the smoke emitted to the surrounding environment is reduced and the environmental pollution is reduced by the selection of the amounts of precipitated calcium carbonate, tricarballylic acid and succinic acid added.
