Abstract

The invention relates to the field of shoes, and discloses a pair of waterproof women's boots and a preparation process thereof. The women's boots comprise vamps and soles, the vamps are treated witha waterproof finishing agent, and the waterproof finishing agent comprises, by weight, 40-50 parts of melamine; 8-10 parts of formaldehyde; 4-6 parts of polymethyl methacrylate; 2-3 parts of dimethylaniline; and 1-2 parts of ammonium persulfate; the preparation method comprises the following steps: preparing the waterproof finishing agent, finishing the vamps by the waterproof finishing agent andsewing the women's boots. Compared with the prior art, the women's boots and the preparation method have the following advantages and effects that melamine and formaldehyde react at a certain temperature to generate a hydroxymethylation product, and an initiator ammonium persulfate and polymethyl methacrylate with good hydrophobicity are further added for reaction, so that the waterproof finishingagent with good waterproof capacity is obtained, and the surface waterproof performance of women's boots is improved.
