White-gasoline-resistant styrene-acrylic emulsion is characterized by comprising, by mass, 12-18% of styrene, 5-15% of methacrylic acid alkyl ester, 5-15% of acrylic acid alkyl ester, 1-5% of hydroxyalkyl ester, 1-5% of alkyl carboxylic acid, 1-5% of functional polymerizable monomer, 0.25-0.5% of initiators, 0.5-2.5% of emulsifiers, 40-60% of water, 1-2% of neutralizers and 1-5% of auxiliaries. Gloss oil prepared by the white-gasoline-resistant styrene-acrylic emulsion can be used for glossing common leatherette paper and applicable to glossy leather imitation treatment of various specialty paper such as the leatherette paper and iridescent paper. Resin liquid which is non-toxic, environment-friendly and economic is added with cosolvent, defoaming agents, wetting agents and wax emulsion to be coated on the paper for white-gasoline-resistant testing, and the paper can be wipe-resistant more than 20 times under the pressure of 1KG, resistant to bend, scratches, water and white gasoline, plump in hand feeling and smooth.
