It spends in the sodium hydroxide solution of 0.3mol/L, 80 DEG C of magnetic agitation 2h, filtration washing, 60 DEG C of oven dryings, obtains alkalization fine coal
Ash；
Step 2 takes 40 parts of phosphoric acid hydrogen zirconiums to be added in 200 parts of deionized water beakers, is placed in constant temperature water bath, at 40 DEG C and
Pre-dispersed 30min under 300rpm revolving speed；
10 parts of ethyl acrylate is slowly added dropwise in step 3, Xiang Shangshu dispersion liquid, continues to stir after being added dropwise, insulation reaction
60min；
Step 4, end of reaction filter to obtain wet gel layer, are transferred in vacuum oven, and dry 5h, grinding obtain at 80 DEG C
Modified phosphate hydrogen zirconium powder body；
3 parts of silane, 1.6 parts of Aluminates, 0.4 part of titanate coupling agent are poured into beaker by step 5, and 20 parts of deionized waters, 4 are added
Part dehydrated alcohol, 80 DEG C of hydrolysis 10min must compound coupling agent；
Step 6 continuously adds 100 parts of deionized waters, 1.5 parts of linear paraffin benzene sulfonic acid sodium salts and 80 parts into above-mentioned compounding coupling agent
Alkalize coal ash and 20 parts of modified phosphate hydrogen zirconium powder bodies, and suction filtration, washing after 15min are reacted at 80 DEG C, and 50 DEG C of 24 h of oven drying are obtained
To composite flame-proof powder；
Step 7 weighs 200 parts of polyethylene, 45 parts of composite flame-proof powders, 9 parts of crosslinking agents, 6 parts of antioxidants, 5 parts by weight
Polyethylene wax and 3 parts of zinc stearates put into high-speed mixer, are stirred 30min blowing；
Step 8 puts into above-mentioned mixture in screw extruder, and extruding pelletization, temperature is controlled at 140 DEG C, finally in injection molding machine
On standard batten is made, under room temperature place 72h after be tested for the property.
The utility model has the advantages that flame retardant type cable material prepared by the present invention, using alkalization flyash and modified phosphate hydrogen zirconium powder body
Compound to obtain fire-retardant powder, composite flame-retardant agent is based on, and supplemented by phosphoric acid hydrogen zirconium, price is more cheap.Phosphoric acid hydrogen zirconium passes through nanometer
Grade ethyl acrylate modification post-tensioning has arrived the interlamellar spacing of laminate, can effectively be embedded in alkalization flyash, pass through phosphoric acid hydrogen zirconium layer
Hydroxyl inside and outside plate and alkalization fine coal gray surface form stable hydrogen bond structure, compared to single flyash and phosphoric acid hydrogen zirconium,
Fire-retardant powder heat resistance after compound significantly improves, and in cable fuel combustion process, fire-retardant powder can be in polythene material table
Face quickly forms layer of charcoal and molten state substance, completely cuts off air, hinders heat transmitting, significantly improves the flame retardant effect of CABLE MATERIALS.In addition,
The hydroxyl condensation of silicone hydroxyl, aluminium hydroxyl, titanium hydroxyl and composite powder surface on compounding coupling agent, forms coupling agent clad,
Hot transmitting and the diffusion of oxygen have been obstructed, has effectively delayed and prevents the thermal degradation of polymer, it is suppressed that volatile combustible group
The generation divided.Flyash is as a kind of industrial solid wastes, and the flame-retardant composition for CABLE MATERIALS reduces the dosage of fire retardant, both
It is economical and environmentally friendly, it has broad application prospects.
