Abstract

The invention discloses a preparation method of a novel golden paper binding material. According to the invention, papermaking waste is used for traditional modification, and the novel golden paper binding material is prepared from the following raw materials in parts by weight: papermaking waste A, papermaking waste B, a pH regulator, a thickening agent, bright yellow and the like. The preparation method comprises the steps of adding the papermaking wastes A and B into the bottom of a reaction kettle in proportion, adding water to dilute to corresponding solid content, uniformly stirring, adding the PH regulator to regulate to corresponding PH, adding the thickening agent, adding the bright yellow, heating, preserving heat, and discharging. The process is simple to operate and easy to control, and has low requirements on a reaction environment.

Description

technical field [0001] The invention relates to the field of preparation of a gold paper binder, in particular to a preparation method of a novel gold paper binder. Background technique [0002] Gold paper binder is mainly used in the production of tinfoil paper (superstition paper). At present, the traditional process is to use papermaking black liquor to acid-precipitate lignin, and use filter cloth to filter naturally to remove water before use. At present, the traditional process will produce a large amount of waste water, which does not meet the requirements of environmental protection and brings great inconvenience to production. Therefore, it is imperative to develop a product that can be used directly without causing waste water. Contents of the invention [0003] The present invention aims to provide a novel gold paper binder and its preparation method to solve the above-mentioned defects in the background technology. [0004] In order to solve the above-mention...
