The application relates to the technical field of paint, in particular to a low-cost dry powder paint special for alcohol-based casting and a preparation method thereof, which comprises the following raw materials in parts by weight: 40-60 parts of mica powder, 20-40 parts of attapulgite, 10-20 parts of kaolin, 2-4 parts of polyvinyl butyral, 4-6 parts of powder, 6-10 parts of additives, and 4-6 parts of bauxite. In the application, solid waste red mud is used as a binder core base material, the surface inert oxide layer of the red mud is stripped through oxalic acid solution activation, the high-activity silicate-aluminate porous framework is exposed, the low-cost bonding system with a three-dimensional network structure is constructed through ball milling and calcium lignosulfonate / temperature-sensitive monomer composite modification, and the bonding durability is enhanced through the ion crosslinking effect of beta-hemihydrate gypsum and magnesium olivine in the mixture. The comprehensive performance of the dry powder paint is ensured, the solid waste replaces traditional high-price silica sol and resin and other raw materials, and the raw material cost is significantly reduced.

The invention relates to an adhesion composition for textiles, comprising a lignosulfonate salt, an epoxy hardener of said salt comprising at least two epoxide units, and an elastomer latex. The lignosulfonate salt can be sodium, potassium, magnesium, ammonium, or calcium lignosulfonate.
