Manufacturing method
of flame retardant
flame retardant is an important part in the field of chemical production raw materials. It is widely used in plastics, rubber, textiles, coatings and other materials to improve its flame retardant performance and prevent fire. This article will introduce several common flame retardant manufacturing methods.

1. aluminum hydroxide flame retardant

aluminum hydroxide is an inorganic flame retardant, with non-toxic, tasteless, smokeless and other advantages, widely used in plastic products. Its manufacturing method is as follows:

1. aluminum salt is reacted with alkali solution to generate aluminum hydroxide precipitate.
2. The precipitate was washed, filtered and dried to obtain the aluminum hydroxide product.
3. through grinding, screening and other processes, made of different particle size of aluminum hydroxide flame retardant.

2. phosphate flame retardant

phosphate flame retardant is an organic flame retardant, with good heat resistance and water resistance, suitable for rubber, coating and other fields. The manufacturing method is as follows:

1. phosphoric acid is reacted with alcohol substance to generate phosphoric acid ester.
2. The phosphoric acid ester is separated from the unreacted raw material by distillation, extraction, etc.
3. The phosphate ester was purified to obtain high quality phosphate ester flame retardant.

3. brominated flame retardant

brominated flame retardant is a common organic flame retardant, with good flame retardant effect and thermal stability, widely used in plastics, rubber and other fields. Its manufacturing method is as follows:

1. Bromine reacts with hydrocarbons to generate brominated hydrocarbons.
2. The brominated hydrocarbon is purified by distillation, crystallization and other processes.
3. The purified brominated hydrocarbon is mixed with other additives to make a brominated flame retardant.

4. nitrogen flame retardant

nitrogen flame retardant is an inorganic flame retardant, with good heat resistance and water resistance, suitable for rubber, coatings and other fields. The production method is as follows:

1. A nitrogen source material is reacted with an acid to generate a nitrogen compound.
2. Nitrogen compounds are separated from unreacted raw materials by filtration, washing, etc.
3. The nitrogen compound is dried, ground, etc. to prepare a nitrogen-based flame retardant.

The above introduces several common flame retardant manufacturing methods. Different flame retardants are suitable for different material fields, and their manufacturing methods will be different. In the process of manufacturing flame retardants, it is necessary to strictly control the quality and proportion of raw materials to ensure the quality and performance of the product. At the same time, it is also necessary to pay attention to the safety and environmental protection issues in the production process to avoid harm to the environment and the human body.

In short, the manufacturing method of flame retardant is of great significance to improve the flame retardant performance of materials and plays a positive role in ensuring the safety of people's lives and property. In the future development, with the continuous progress and application of science and technology, the manufacturing methods of flame retardants will continue to innovate and improve, providing strong support for the development of chemical production raw materials.
