Read： 460 Time：18months ago Source：Transform the World with Simplicity

Plastic products have been widely used in modern society, at the same time, due to its relatively low ignition point, resulting in security risks. In order to improve the safety of plastic products, people have adopted a variety of methods, one of which is to add flame retardants to plastics. This article will introduce the production process and preparation method of flame retardants for plastics.

1. Production Process
The production process of flame retardants for
plastics mainly includes the following five steps:

1. Selection of flame retardants: Select suitable materials from various flame retardants. Regular manufacturers should make careful consideration and choice according to the quality, purity, stability and high temperature grade of the flame retardant.

2. Feeding and mixing: Mix the selected flame retardant with the plastic. The mixing method can be manual mixing or mechanical mixing, and it is necessary to formulate a suitable flame retardant addition ratio to ensure the flame retardant performance of the product.

3. Processing and manufacturing: After mixing evenly, the plastic is processed to make the required products. This process needs to have a strong technical, according to different product requirements, can use injection molding, extrusion, blow molding and other processing methods.

4. Heat treatment: Heat treatment of the finished product to improve its flame resistance. For different flame retardants, the processing temperature and treatment methods are also different.

5. Performance test: The finished product needs to be tested to verify the effect of the flame retardant and ensure the quality of the product.

2. preparation method

plastic flame retardant preparation method also has a variety of common including:

1. ion exchange method: the use of cation exchange agent treatment of flame retardant, in order to improve its dispersion and stability.

2. Chemical blending method: the flame retardant is added to the plastic, and the chemical reaction is used to form a new molecular structure with the plastic molecules.

3. Surface coating method: The flame retardant is coated on the plastic surface in a certain proportion to improve the flame resistance of the product.

The above three methods can be used for the preparation of flame retardants for plastics. According to specific needs and requirements, the performance of flame retardants prepared by different methods will be different.

3. summary

This paper briefly introduces the production process and preparation method of flame retardants for plastics, and it is very important to choose the right flame retardant according to different application scenarios and requirements. In the production process, it is necessary to pay attention to details such as processing temperature and uniform mixing to prepare higher quality products. In the future, people can develop more efficient, safe and stable flame retardants through continuous technological research and development and innovation to adapt to changing market needs.
