Abstract

The invention provides a special adhesive for stone paper and a preparation method thereof. It is characterized in that: the adhesive contains microfibers, and the components are calculated in parts by weight: 40-55 parts of seaweed glue powder, 15-20 parts of alkyd resin, 10-25 parts of reinforcing fiber, and 0.5-parts of organic silicon 1 part, 0.5‑1 part of dispersant, appropriate amount of water; use the penetration of alkyd resin and the thickening of seaweed glue powder to make the stone paper bond quickly through the connection of fine fibers, especially the adhesive can be used in hot water Dispersion, to realize the bonding process of stone paper on traditional paper product processing equipment.

Description

technical field [0001] The invention relates to the field of adhesive materials, in particular to a special adhesive for stone paper, and further relates to a preparation method of the adhesive. Background technique [0002] The paper industry is considered internationally as an industry that pollutes and damages the environment, and is also a large consumer of wood and energy. my country is a country with extremely scarce forest resources, and it has been difficult for a long time to get rid of the fact that most pulp fibers depend on imports. In the pulp production process of the paper industry, cooking, bleaching, washing, drying and other operations are required, which will discharge a large amount of waste gas and waste water, causing serious deterioration of the ecological environment of the sewage drainage basin. Stone paper is an environmentally friendly paper product made of inorganic stone powder as the main raw material, adding a small amount of synthetic resin a...
