Nano-wear-resistant polyurethane heel lift composite material and preparation method

Abstract

The invention relates to a nano-wear-resistant polyurethane heel lift composite material and a preparation method. By means of nano composite technology, a polyurethane heel lift is modified, and the mechanical strength and the comprehensive performance of the materials are improved. Materials on an upper material layer A and materials on a lower material layer B are successively filled into a mould by a filling machine according to a certain time interval, are extruded by a flat vulcanizing machine at a certain pressure and a certain pressure, and are solidified into a whole to obtain the nano-wear-resistant polyurethane composite heel lift, the wear resistance and flexibility of the lower material layer B of the heel lift are improved, the upper material layer A has good hardness and strength and is stably engaged with a pinned top piece, the hydrolysis resistance, the impact strength and the like of the heel lift are further improved, the service life of the heel lift is effectively prolonged, noise generated by knocking the ground with the heel lift in use is lower, and quality in use of women's leather shoes is improved.

Description

technical field [0001] The invention relates to the field of wear-resistant pads for high-heeled shoes, in particular to a nano-wear-resistant polyurethane skin composite material and a preparation method thereof. Background technique [0002] Women's leather shoes are not only huge in quantity, but also in various styles, which add great interest to women's life. Women's leather shoes are different from most men's leather shoes in that they have heels of different heights to meet the needs of different professional occasions and women of different ages. Women who wear high heels can not only make their bodies look taller, but also boost their spirits. Usually, the bottom of the heel of women's high-heeled shoes is usually equipped with a detachable and replaceable sky cortex to prevent the heel of the shoe from being worn out. Usually, the sky cortex is installed in the pre-set mounting holes at the bottom of the heel of the high-heeled shoes through sky nails . Most of ...

Problems solved by technology

However, inorganic nanomaterials have high surface activity and large specific surface area, and the particles are in a non-thermodynamic stable state, so they are prone to agglomeration.

In addition, its surface or interface properties are different from those of the organic polymer matrix, and its compatibility is poor, so it is difficult to disperse evenly in the matrix, and direct or excessive filling often leads to the reduction of certain mechanical properties of the material
