Abstract: |
This article studies the preparation and performance of microencapsulated paraffin insulation mortar. By using silane couplings to modify the surface of the microencapsulated paraffin, and introducing fibers to solve cracking of the mortar. The interactions of silane couplings, microencapsulated paraffin, fibers on the mechanics properties of microencapsulated paraffin insulation mort were discussed. The results showed the type of silane couplings effect the process and mechanical properties of mortar, KH550 and KH560 present good performance. The compressive strength and flexural strength were enhanced with increasing of concentration of silane couplings. Polypropylene fibers can improve the crack-resistant of the insulation mortar. With increasing the dosage of fiber, the performance of the insulation mortar is improvement. With the increase in the dosage of the microencapsulated paraffin, the denseness and the compressive and flexural strength of insulation mortar decreases and the toughness changes for the better after the first worse.
