Preparation and Application of Microencapsulated Flame Retardant Containing Phosphorus-Silicon

Abstract:

The silica sol containing epoxy groups was prepared with tetraethoxysilane and silane coupling agent GPTMS as precursors by sol-gel technique and was used to encapsulate the microencapsulated flame retardant to enhance its flame retarding efficiency and water fastness for textile material. The prepared silica sol and gel were characterized by nano particle size analyzer, FT-IR spectrum analysis, energy spectrum analysis and SEM. The experimental results were proved that silica gel containing epoxy group was assuredly deposited on the surface of microencapsulated flame retardant. The cotton fabric was finished by the modified flame retardant and the test results (including the test of flame spread properties of textiles in vertical direction and the fastness to washing) showed that it had better flame retarding efficiency and water fastness.
