Flame retardant material
At present, the reserves of the mineral resources of the concave and convex rods can fully meet the needs of industrial production, and have obvious performance advantages compared with other countries in the world. Attapulgite has good long diameter ratio and rich inside the pores, is better enhanced materials with flame retardant effect, at high temperatures to lose water and water vapor can oxygen barrier, and can produce thermal stability good to MgO, Al2O3 oxide isolation layer. Implications of poly ammonium phosphate (APP) and Tris 2-hydroxyethyl isocyanurate urea acid ester (THEIC) as intumescent flame retardant (IFR), taking attapulgite (ATP) as synergistic agent by melt blending process with the preparation of a flame retardant properties of high density polyethylene (HDPE) composites, through the composite infrared spectroscopy, oxygen index and thermal weight loss and cone calorimetry analysis, ATP on combustion conditions affecting the performance of the Flame Retardant HDPE.
The results showed that adding a small amount of ATP esterification reaction catalyzed APP-THEIC, improve the flame retardant property of HDPE; HDPE, IFR, ATP concentration for 70%, 28% and 2% of the HDPE-IFR-ATP composite, its oxygen index reached 30%, flame retardant grade improve V-0, system of heat release peak rate and total heat release than HDPE and mass fraction of the intumescent flame retardant for 70%, 30% of the HDPE-IFR composite were reduced by 22.7% and 26.7%.

Application of building materials industry
Dolomite attapulgite clay as coating agent, leveling agent, thickener and stabilizer, its good performance, low cost, instead of the traditional PCC. In the electron microscope, the coating of the coating of the concave and convex rods is observed in the electron microscope, the crystal is in a reticular arrangement, and the coating is evenly distributed in the organic bond.
Concave and convex clay ore

In the agent, therefore, the coating is resistant to washing and cleaning. Accept, especially of attapulgite clay in the external stirring dispersion, the formation of stable electrolyte is destruction of the suspension, the coating does not precipitate, stratification, and traditional 106 coating compared with a variety of advantages: brushing performance is good, not sagging, saving titanium dioxide amount, but also can be used as paint filler wall material packing production ceiling wall board, its characteristics are: to moisture, emission performance is strong, not expansion deformation, bond performance is good, lightweight toughness, with heat insulation, sound absorption, anti moth, anti sag is strong, can adapt to air temperature change, and no deformation.
