This application relates to the field of metal surface treatment, specifically disclosing a fingerprint-resistant galvanized sheet and its production method. The fingerprint-resistant galvanized sheet includes a substrate, a galvanized layer formed on the surface of the substrate, and an inorganic passivation layer and an organic composite coating sequentially coated on the surface of the galvanized layer. The organic composite coating includes an acrylate-polysiloxane modified resin system and a hybrid conductive network filler dispersed in the resin system. The hybrid conductive network filler is composed of two-dimensional nano-graphene and one-dimensional conductive material in a mass ratio of 5:1 to 15:1, and the surface of the hybrid conductive network filler is grafted with a silane coupling agent. The organic composite coating is distributed in a transverse gradient on the surface of the galvanized sheet, with a film weight of 0.8-1.0 g / m² in the central region and 0.6-0.8 g / m² in the edge region. The fingerprint-resistant galvanized sheet of this application exhibits excellent fingerprint resistance and corrosion resistance, while also achieving high conductivity.

The application discloses a kind of concrete internal curing agent for high-temperature underground chamber and its preparation method, belong to concrete material technical field.The internal curing agent is composed of sealing film liquid and superabsorbent polymer, sealing film liquid is compounded by epoxy modified polyurethane emulsion, nano silicon dioxide, carboxyl-containing acrylate copolymer, temperature-sensitive polyether polyol and coupling agent in proportion, form the core-shell structure with sealing film liquid as shell, SAP as core, with good high-temperature resistance and alkali resistance.The internal curing agent does not affect the working performance of concrete, in the high-temperature environment of 30~90 DEG C, when the hydration process of cement causes the pH value of pore solution in concrete to rise, the temperature of concrete rises and internal water shortage occurs, sealing film gradually ruptures under the synergistic effect of high temperature and high alkali, releases the water stored by SAP, provides the required free water for the continuous hydration of cement in concrete, effectively improves the strength and durability of concrete under high-temperature conditions.

The invention relates to the technical field of building decoration materials, and particularly discloses a metal texture interior wall decoration plate and a preparation method thereof. The interior wall decorative plate with the metal texture sequentially comprises a base plate, a permeation enhancing layer, an adhesive layer and a metal facing layer from bottom to top. The permeation enhancing layer is prepared from the following raw materials in parts by mass: 80 to 120 parts of modified polyurethane resin, 40 to 60 parts of self-crosslinking silicone acrylic emulsion, 4 to 8 parts of nano silicon dioxide, 40 to 60 parts of reactive diluent, 3 to 6 parts of silane coupling agent, 2 to 4 parts of organic fluoride, 3 to 5 parts of curing agent A, 2 to 4 parts of photoinitiator, 2 to 4 parts of dispersing agent and 1 to 2 parts of defoaming agent. The metal texture interior wall decorative plate prepared by the invention has excellent interlayer bonding strength and water resistance.
