Abstract

The invention discloses a serpentine flame retardant preparation technology including the following steps: (1) respectively using a jaw crusher and a hammer crusher for two stage crushing treatment of raw serpentine ore to obtain serpentine ore powder; (2) weighing the serpentine ore powder, adding water and a dispersant for mixing, grinding until the average particle size of ore pulp is 1-5 mum, discharging the ore pulp to a mixing barrel, adding water to adjust the ore pulp concentration to be 30-50%; (3) taking silane coupling agent accounting for 0.5-0.8% by weight of the serpentine ore powder to add into the mixing barrel, mixing for reaction for 100-120 minutes, filtering, and washing; and (4) drying, adding titanate coupling agent accounting for 0.5-1.0% by weight of the serpentine ore powder and stearic acid accounting for 0.8-1.2% by weight of the serpentine ore powder at 100-150 DEG C. According to the serpentine flame retardant preparation technology, serpentine is treated by wet and dry method modification, modification effect is good, and the compatibility of the modified serpentine and a polymer material is increased, and the prepared flame retardant can meet the application requirement of all kinds of high polymer materials.

Description

technical field [0001] The invention relates to the technical field of fire protection products, in particular to a preparation process of a serpentine flame retardant. Background technique [0002] Flame retardants are a class of additives that can prevent polymer materials such as plastics from being ignited or inhibit the spread of flames. Serpentine is a general term for a hydrous magnesium-rich silicate mineral, which has the characteristics of heat resistance, corrosion resistance, wear resistance, and heat insulation. Serpentine is currently used as a heat-resistant material, but serpentine minerals are fibrous or leaf-like minerals, and the polymer materials produced have low melting index during processing, poor material fluidity, rough surface, and low flame-retardant efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a preparation process for serpentine flame retardant...
