Leather glue prepared by adopting waste materials and preparation method thereof

Abstract

The invention relates to leather glue prepared by adopting waste materials and a preparation method thereof. The glue comprises raw materials of 45-55 portions of special base glue mother liquid, 6-10 portions of special organosilicone coupling agent, 10-15 portions of natural emulsion, 1.5-3 portions of salt polyacrylate, 0.5-1 portion of dinaphthyl sodium sulfonate, 0.5-1 portion of sodium salicylate, 0.5-1 portion of methyl dinaphthyl sodium sulfonate, 1.5-3 portions of zinc oxide and 1-6 portions of calcium carbonate, wherein the special base glue mother liquid is prepared by adopting No.200 solvent naphtha to dissolve waste polystyrene and waste rubber tires, and the special organosilicone coupling agent is obtained in such a way that asphaltum and waste glass react in a high-temperature reactor. The raw materials are put in a retort and are evenly stirred at the temperature of 65-100 DEG C so as to be processed by polymerization for 2 hours, and a binder of the invention is obtained after cooling the product of reaction. The invention adopts waste plastic and rubber as raw materials, thereby being beneficial to reducing environmental pollution, saving material resources, having low production cost and being suitable for the binding of various materials, in particular the binding of soft materials such as leather, and the like.

Problems solved by technology

[0002] At present, there are various formulations of cavity adhesives, and the performance of the adhesives varies greatly according to their respective components. However, most adhesives, such as phenolic resin adhesives, contain harmful substances such as benzene, toluene, xylene, and formaldehyde. Use Not only may it cause serious pollution indoors, but it will become an important source of harmful substances such as formaldehyde, which will damage people's health. In addition, the manufacturing process of these adhesives is relatively complicated and the cost is relatively high.

[0003] On the other hand, the amount of polystyrene foam plastics and rubber products in my country is increasing, and most of them are for one-time use. Millions of tons of white garbage and waste rubber products are scattered in nature and cannot be decomposed and transformed. It cannot be degraded naturally, causing serious pollution. The current treatment methods for these pollutants are generally incineration and landfill. Among them, landfill will occupy a large amount of land, and incineration will cause new air pollution problems.
