Pigment reinforcing layer material of oil colored paintings of ancient architecture and preparation technology thereof

The invention discloses a pigment reinforcing layer material of oil colored paintings of ancient architecture and a preparation technology thereof. The pigment reinforcing layer material of the oil colored paintings of the ancient architecture comprises a methyl methacrylate, a butyl acrylate, an acrylic acid, an N-hydroxymethyl acrylamide, an organosilicon A171, Parsol1789, an emulsifying agent, an alcohol ester-12, a defoaming agent, a flatting agent and a persulfate initiating agent. The preparation technology comprises the following steps of: preparing an organosilicon modified polyacrylate micro-emulsion by using free radical emulsion polymerization. The micro-emulsion prepared by the invention is semitransparent, has no granular condensation products, relatively good mechanical stability, freeze thaw stability and dilution stability, shows favorable performances in the light stability, the chrominance, the adhesion strength, the water resistance, the water absorption and the corrosion resistance after b
