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
The present invention relates to fire product technical field, particularly relate to a kind of preparation technology of serpentine fire retardant.
Background technology
Fire retardant is that a class can stop the macromolecular materials such as plastics ignited or suppress the auxiliary agent of propagation of flame.Serpentine is a kind of general name of moisture rich magnesium silicate mineral, has the characteristics such as heat-resisting, corrosion-resistant, wear-resisting, heat insulation.The application of current useful snake masonry heat-stable material, but serpentine minerals is threadiness or foliated lamellar mineral, and during obtained processing of high molecular material, melting index is low, and material fluidity is poor, surface irregularity, and flame retarding efficiency is low.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of preparation technology of serpentine fire retardant is provided, first carry out wet method super-fine, carry out surface modification process again, then carry out dry surface modification process during drying, by wet-process modified and dry modification serpentine, there is modified effect good, increase the consistency of modification serpentine and macromolecular material, the fire retardant of preparation can meet the application requiring of all kinds of macromolecular material.
The present invention adopts following technical scheme to achieve these goals:
A preparation technology for serpentine fire retardant, comprises the following steps:
(1) by the process of serpentine crushing raw ore, adopt jaw crusher, hammer mill to carry out two-stage break process to serpentine raw ore respectively, obtain serpentine breeze;
(2) take a certain amount of serpentine breeze, add water and dispersion agent size mixing, fine grinding of then pulling an oar, being ground to ore pulp median size is after 1-5um, blowing to agitation vat, add water size mixing to concentration be 30-50%;
(3) silane coupling agent getting serpentine ore grain weight amount 0.5-0.8% joins in agitation vat, and stirring reaction 100-120 minute, filters ore pulp after reacting completely, washing;
(4) drying is carried out to the ore pulp of step (3), titanate coupling agent and stearic acid is added at 100-150 DEG C of temperature, the add-on of described titanate coupling agent is the 0.5-1.0% of serpentine ore grain weight amount, and stearic add-on is the 0.8-1.2% of serpentine ore grain weight amount.
Dispersion agent described in step (2) is Sodium hexametaphosphate 99.
Compared with the prior art, beneficial effect of the present invention is as follows:
The preparation technology of serpentine fire retardant of the present invention, first carry out wet method super-fine, carry out surface modification process again, then dry surface modification process is carried out during drying, dispersion agent is added in wet method super-fine process, regulate the rheological property of ore pulp and the surface electrical behavior of ore particle, reduce the viscosity of ore pulp, promote the dispersion of particle; Add silane coupling agent after ultra-fine and surface modification is carried out to powder; After wet-process modified, add titanate coupling agent, stearic acid carries out dry surface modification, after this treatment process that is wet-process modified and dry modification has modified effect, increase the consistency of modification serpentine and macromolecular material, the serpentine fire retardant of preparation can meet the application requiring of all kinds of macromolecular material.
