This invention relates to the field of corrosion protection, specifically to a wear-resistant and corrosion-resistant material and coating, their applications, and a wear-resistant and corrosion-resistant paint, its preparation method, and applications. The wear-resistant and corrosion-resistant material of this invention includes a wear-resistant and corrosion-resistant coating, the composition of which includes: epoxy resin, phenol-modified graphene, filler, nonionic dispersant, and curing agent; the epoxy resin includes phenolic epoxy resin and bisphenol A epoxy resin; the phenol-modified graphene includes graphene oxide and phenolic substances formed on the graphene oxide. The wear-resistant and corrosion-resistant paint of this invention has advantages such as good stability, good brushing performance, and simple construction process; the prepared coating exhibits excellent wear resistance, good acid / alkali resistance, strong adhesion, and good toughness.

The application discloses a chromium-free inorganic surface treatment agent for galvanized steel plate, which contains 11.5-15% of total solid content in mass percentage in an aqueous solution, and components of the total solid content are as follows: a compounded silane coupling agent A, which accounts for 45-65% of the total solid content in mass percentage; a surface modified water-based silica sol B, which accounts for 25-45% of the total solid content in mass percentage; a water-soluble phosphorus-containing compound C, which accounts for 0.5-1% of the total solid content in mass percentage of phosphorus element; a water-soluble fluorine-containing compound D, which accounts for 1-6% of the total solid content in mass percentage of fluorine element; and a lubricating aid E, which accounts for 1-10% of the total solid content in mass percentage; wherein the compounded silane coupling agent A is compounded by four types of silane coupling agent monomers, i.e., a silane A1 with an epoxy group, a silane A2 with a mono-amino group, a silane A3 with an alkyl group and a silane A4 with a vinyl group.

This invention relates to a concrete waterproofing agent and its preparation method. Using hydroxyl acrylate monomers (or hydroxymethyl acrylate), long-chain acrylates (or long-chain methyl acrylates), and short-chain acrylates (or short-chain methyl acrylates) as raw materials, a poly(meth)acrylate polymer containing hydroxyl and long-chain alkyl groups is first prepared by bulk copolymerization. Then, an isocyanate silane coupling agent is used in this polymerization reaction to obtain a silane-containing long-chain alkyl polyacrylate compound (Si@Poly long-chain alkyl acrylate, Si@PLAA). This polymer (Si@PLAA) is then mixed with an emulsifier and a dispersant, and after emulsification, a waterproofing agent emulsion is obtained.
