Resin flame retardant is a commonly used fireproof material, which can be used in various occasions requiring fire prevention. The production process and preparation method of resin flame retardant has become one of the research hotspots in related industries. This article will detail the production process and preparation method of resin flame retardant.

1. the performance and classification of resin flame retardants

resin flame retardants refer to the addition of some chemicals to the resin to improve its fire resistance. There are many types of resin flame retardants, which can be divided into the following categories according to the added components: alumina flame retardants, aluminum silicate flame retardants, aluminum phosphate flame retardants, halide flame retardants, etc. Their main function is to produce inert gas in the event of a fire, thereby suppressing the spread of the flame.

2. resin flame retardant production process

1. reaction polycondensation method

reaction polycondensation method refers to the chemical reaction, so that the original molecular structure of the material is changed, and then make it high temperature, with fire resistance. In this method, the resin and flame retardant are first mixed at a certain temperature, and then reacted for a certain period of time, and finally a product with fire resistance is obtained.

2. Solution mixing method

The solution mixing method refers to dissolving the resin and the flame retardant in different solvents, and then mixing the two solutions. This method can effectively prevent the reaction temperature from being too high, but requires a large amount of solvent and a long reaction time.

3. Synergy

Synergy refers to the mixing of multiple flame retardants to enhance fire protection. This method requires selection and testing of the resin base material and use requirements to find the best pharmaceutical combination formulation.

3. resin flame retardant preparation method

1. Solution method

solution method is the flame retardant and solvent evenly mixed to achieve a paste, and then added to the resin, after stirring and extrusion processing and made. This method makes it possible to obtain a resin material having excellent fire resistance.

2. Additive method

additive method is to melt the fire retardant prepared in advance with the resin base material, and then process it. This method can reduce production costs, but it is necessary to select suitable resins and fire retardants, and strictly control the quality of additives.

3. surface coating method

surface coating method is to disperse the fire retardant on the resin surface in a way that does not affect the properties of the resin material. This method is relatively simple, but the specific implementation should consider the anti-shedding performance and wear resistance of the coating layer. Application of Flame Retardant for
