Abstract

PURPOSE:To obtain synthetic leather having reduced weight of synthetic leather, improved heat insulation and characteristics of natural leather, by adding fine hollow particles to a mixture of fine powder of natural leather and resin. CONSTITUTION:(A) Fine powder (<=40mum particle diameter) of natural leather is blended with (B) a resin (e.g., vinyl chloride resin or polyurethane resin) and (C) fine hollow particles such as borosilicate glass having 0.15-0.19g/cc bulk specific gravity and 10-250mum particle diameter in the ratio of the component A:B:C=5:3:2, sufficiently dispersed and molded to give synthetic leather in a sheetlike shape, etc.

In other words, the bulk specific gravity of the micro hollow particles is, for example, a particle size of 10 to 2.
0.15 to 0.0 in the case of 50 μm borosilicate glass.
The bulk specific gravity of the mixture of natural leather fine powder and polyurethane is about 19g/CC (0.38~0.50g/c).
Therefore, by containing an appropriate amount of micro hollow particles,
without impairing the properties of the mixture of natural leather fine powder and resin.
The weight of synthetic leather can be sufficiently reduced.

その上、微小中空粒子に封入されている気体の断熱作用
