Problems solved by technology

In the prior art, the general leather products are processed and shaped through the production line, and it is inevitable that there will be defective products with burrs on the outer edge or unformed embossing. If the defective products are directly discarded, raw materials will be wasted; and for high-end leather products , It needs to be made by hand, and the edge embossing is also a problem. The traditional way of edge sealing is generally dry naturally. You can't use other means to make the edge dry quickly, which will reduce the overall work efficiency. Not only that. This method will also complicate the edge coating process. In order to solve the above technical problems, a new technical solution is proposed.

preparation example Construction

[0036] The preparation method of this edge sealing coating comprises the following steps:

[0037] Step 1: Add high-solid polyurethane resin into the reactor, which is a stainless steel reactor, and turn on the stirring device of the reactor;

[0038] Step 2: Slowly add the high temperature resistant slip additive into the reactor, adjust the rotation speed of the stirring device of the reactor to 700 revolutions per minute, and adjust the temperature inside the reactor to 20°C;

[0039] Step 3: Add the defoamer dropwise to the inside of the reactor, and the dropping tool is a dropper, adjust the speed of the stirring device of the reactor to 700 revolutions per minute, and adjust the temperature inside the reactor to 20°C;

[0040] Step 4: Add the leveling agent dropwise to the inside of the reactor. The dripping tool is a dropper. Adjust the rotation speed of the stirring device of the reactor to 700 revolutions per minute, and adjust the temperature inside the reactor to 20...

Abstract

The invention provides a leather product edge sealing agent and particularly relates to a leather product edge sealing coating. The leather product edge sealing agent comprises two leather layers and an extrusion layer. The extrusion layer is arranged between the two leather layers, the extrusion layer and the leather layers are connected through glue, an edge sealing layer is arranged on the tops of the leather layers, and the edge sealing layer is in an arc shape or is a smooth curve. High-solid-content polyurethane resin has the effects of enhancing the elasticity of the coating and improving toughness and being capable of adjusting the thickness and glossiness of the coating; a high-temperature-resistant slip sense additive has the effect of achieving a smooth and stiff effect after high-temperature edge ironing; a flatting agent has the effect of achieving a smooth effect after edge coating; a defoaming agent has the effect of avoiding bubbles in the edge sealing process; an associating assistant has the effect of being capable of adjusting the viscosity of a product and improving the stability of various substances in the formula; a film drying preventing additive has the effect of being capable of preventing the coating from being sun-cracked during high-temperature edge ironing. The edge sealing time can be shortened through the edge sealing coating, edge sealing is rapider, and the edge sealing process becomes simpler.

Description

[0001] Technical field: [0002] The invention relates to an edge-sealing coating for leather goods, in particular to an edge-sealing agent and an edge-sealing method for leather goods. [0003] Background technique: [0004] When processing leather goods, in order to make the overall effect beautiful and tidy, it is necessary to emboss the edges of the leather goods. In the prior art, the general leather products are processed and shaped through the production line, and it is inevitable that there will be defective products with burrs on the outer edge or unformed embossing. If the defective products are directly discarded, raw materials will be wasted; and for high-end leather products , It needs to be made by hand, and the edge embossing is also a problem. The traditional way of edge sealing is generally dry naturally. You can't use other means to make the edge dry quickly, which will reduce the overall work efficiency. Not only that. The way will also make the process of e...
