Nanometer flame retardant shoe insole material
2012
The invention discloses a nanometer flame retardant shoe insole material and belongs to the field of preparation of shoe materials. The shoe insole material is prepared through the following steps of: dipping a non-woven fabric in a dip material and drying the non-woven fabric, wherein the non-woven fabric is made of polyester staple fibers and aluminium silicate fibers through a needle punching technology in a mass ratio of 7:3, and the dip material is prepared from the following raw materials in parts by weight: 20-60 parts of nanometer magnesium hydroxide, 20-40 parts of nanometer aluminium hydroxide, 5-15 parts of nanometer antimonous oxide, 10-30 parts of nanometer silicon oxide, 20-30 parts of zeolite, 100-300 parts of water and 200-600 parts of styrene-acrylic emulsion. The nanometer flame retardant shoe insole material provided by the invention has the advantages that a nanometer flame retardant material is added on the basis of non-woven fabric insole leather, and the synergistic effect of the nanometer flame retardant material can be used for greatly increasing the flame retardant property of the insole material, so that the safety of workers is ensured; and simultaneously, the additive amount of the nanometer flame retardant material is much less than that of other flame retardant material, and therefore, the production cost of the flame retardant shoe material is reduced.
