Abstract

The invention provides a full grain leather polishing mending cream, which comprises the following components in mass percent: 2-20% of thermal expansion hollow microspheres, 10-30% of modified protein adhesive, 10-30% of fischer tropsch wax emulsion, 1-10% of silicon resin emulsion, 0.1-2% of thickener, 0.1-2% of preservative, 10-30% of water, and 15-45% of multiple curable aqueous hyperbranched polyurethane inorganic nanometer material hybrid coating agent. The invention uses the multiple curable aqueous hyperbranched polyurethane inorganic nanometer material hybrid coating agent which has high cushion resistance performance and is suitable for polishing. At the same time, silicon resin with cushion resistance and smoothness and high melting point wax is added to improve the polishing property of the mending cream greatly. By applying the full grain leather polishing mending cream provided by the invention to the slight mending of full grain leather, brush complement and polishing of coarser grain can greatly improve the rate of finished leather and added value, and increase the economic benefit of enterprise.

Description

technical field [0001] The invention belongs to the field of leather polishing, in particular to a full-grain leather polishing paste. Background technique [0002] In the past, the repair treatment of leather usually refers to the repaired leather. The damage of the leather blank is relatively serious. It needs to be ground with fine sandpaper to grind off the damaged part or the coarser grain surface, and then repair it with a repair agent. The depth that still exists is repaired, and finally the finishing material is used to modify it into a relatively flat and fine pseudo-grain layer similar to natural leather. This kind of leather repair agent can be used for spot repair, brush repair, rolling repair, and then it can be sanded and ironed after it is completely dry. There are no products with better effects on the market for repairing wounds on full-grain leather. Contents of the invention [0003] The present invention aims at the shortcomings of the above-mentioned...
