Abstract

The invention discloses aqueous wax emulsion for improving the brightness of leather. The aqueous wax emulsion is prepared by using a direct high temperature sealed emulsification method, that is, adding water, a surfactant, an emulsification synergist, oxidized polyethlene wax and other additives into a reaction kettle, sealing, heating and stirring, emulsifying for a while, and subsequently cooking, thereby obtaining the polyethlene wax superfine microemulsion. Due to adoption of the emulsification synergist, the dispersion stability of the wax emulsion is improved.

Description

technical field [0001] The invention relates to a preparation method of polymer wax, in particular to a water-based wax emulsion for increasing leather brightness. Background technique [0002] Oxidized polyethylene wax emulsion is used in water-based ink, water-based varnish, agriculture, leather, shoe polish, forestry, wood industry, garden industry, water-based paint, water-based paint, paper product adhesive, textile softener and water-resistant finishing and other fields. It has small particle size, good water resistance, high coating film hardness, and non-sticky hands. It is an excellent additive for coatings, leather, textiles, and inks. It can also be used in the fields of ink, polish, polish wax, liquid shoe polish, liquid car polish, liquid floor wax, and liquid leather jacket polish. [0003] CN102030996 relates to a water-soluble OP wax emulsion and a preparation method thereof. The OP wax emulsion is composed of certain parts by weight of OP wax, fatty alcohol...
