Abstract

The invention discloses inorganic particle composite polyurethane synthetic leather and a preparation method and application thereof. The inorganic particle composite polyurethane synthetic leather isprepared from a composite material A and a composite material B according to a mass ratio of 100:(40-80) through solvent-free reaction. The composite material A is prepared from, by mass, 90-120 parts of biomass polyether polyol, 30-50 parts of polyether polyol, 5-12 parts of a chain extender, 2-5 parts of a foaming agent, 1-10 parts of a catalyst, 5-15 parts of an inorganic nano composite material and 10-30 parts of an inorganic flame retardant. The composite material B refers to cyanate ester organics. Organic solvent consumption is avoided in a manufacturing process, and the prepared inorganic particle composite polyurethane synthetic leather has excellent flame retardation and mechanical properties, high resistance to light and heat and long service life and has evident economic and environment-friendly advantages in application to automotive interior decorative materials.

Description

technical field [0001] The invention belongs to the field of polyurethane synthetic leather, and in particular relates to inorganic particle composite polyurethane synthetic leather and its preparation method and application. Background technique [0002] Polyurethane synthetic leather belongs to the category of polyurethane elastomers. It has soft and natural luster, soft touch, and a strong leather-like appearance. It has excellent mechanical properties such as excellent adhesion to substrates, wear resistance, flex resistance, and aging resistance. At the same time, it also has the advantages of good cold resistance, breathability, washability, convenient processing, and low price. It is the most ideal substitute for natural leather. [0003] As one of the pillar industries of my country's national economy, the automobile industry has been leading the world in production and sales for many years, and will continue to maintain a positive development trend in the future.
