Embodiment Construction

[0016] The preparation process of the high-performance environment-friendly PAL flame-retardant material is characterized in that the process comprises the following steps:

[0017] A. Separation and purification: The impurities in the PAL material raw materials are removed through separation and purification.

[0018] B. Depolymerization and dispersion: Depolymerization and dispersion is carried out by using a target plate type liquid flow pulverizer, that is, the high-purity PAL material is carried by the high-speed liquid flow as the medium, and collides with the fixed target plate, and the material and the target plate collide and collide at high speed. , the high-speed function of the liquid flow is finally converted into the crushing energy of the material, so that the material is broken; the purification is realized by using a screw propulsion centrifuge, that is, during the high-speed advancement of the screw of the screw centrifuge, the gravity of the particle size of ...

Abstract

The invention relates to the technical field of flame-retardant materials, in particular to a preparation process for a high-performance environmentally-friendly PAL (Phenylalanine Ammonia-Lyase) flame-retardant material, which solves the technical problems of low reasonability and the like existing in the prior art. The process comprises the following steps of: A, separating and purifying; B, depolymerizing and dispersing; C, inorganically activating; and D, organically modifying. Compared with the prior art, the preparation process for the high-performance environmentally-friendly PAL flame-retardant material has the advantages of simple working procedure, easiness in implementation, low environmental pollution, low production cost and high product quality.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a preparation process for high-performance and environment-friendly PAL flame retardant materials. Background technique [0002] Flame retardant is of great importance to human health and safety and social and economic development, and its significance is self-evident. In the fields of construction, chemical industry, military, transportation and other fields with their own fire protection needs and in the field of flammable polymer materials, the proportion of flame retardant materials in reducing fire hazards is as high as 70%. Practice has proved that flame retardant materials play an important role in reducing fire casualties, avoiding major economic losses and protecting the ecological environment. Therefore, the research, production and application of flame retardants and flame retardant materials are important for social and economic development. and the...
