White sports shoe upper leather coating process

The invention relates to a prime coat chemical material, which is prepared from the following components in parts by weight: 250 to 400 parts of water, 10 to 80 parts of penetrant, 100 to 200 parts of medium-soft aliphatic polyurethane resin, 100 to 150 parts of adhesive aliphatic polyurethane resin, 100 to 150 parts of methacrylic resin, 40 to 100 parts of inorganic silicate filler, 20 to 80 parts of soft synthetic wax emulsion and 100 to 150 parts of inorganic titanium dioxide pigment. The top layer protection material is prepared from the following components in parts by weight: 200 to 400 parts of water, 100 to 300 parts of bright aliphatic polyurethane resin, 50 to 200 parts of water-based acetic acid cotton, 10 to 30 parts of polycarbodiimide and 10 to 30 parts of organic silicon feeling agent. According to the white sports shoe upper leather finishing process, water-based materials are completely adopted, VOC emission is avoided, environment friendliness is achieved, the industrial sustainable developm
