Abstract
The invention discloses wax emulsion for improving the wear resistance of water-based ink. The wax emulsion is prepared by using a high-temperature sealed emulsification method directly and the high-temperature sealed emulsification method comprises the following specific steps: adding water, a surfactant, a synergist, oxidized polyethlene wax, polyethylene wax and other additives into a pressure reaction kettle at one time, sealing, heating and stirring, emulsifying for a certain time, and cooling, thereby obtaining superfine micro emulsion. Due to adoption of the wear-resisting synergist, the dispersion stability of wax emulsion and the wear resistance of the water-based ink are improved.
Description
technical field [0001] The invention relates to a preparation method of polymer wax, in particular to a wax emulsion for increasing the abrasion resistance of water-based ink. Background technique [0002] Microemulsion is used in water-based paint and water-based ink industry: it can improve the scratch resistance, surface hydrophobicity and anti-sticking and anti-fouling properties of the coating film, making the coating film smoother. [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 polyoxyethylene ether, fatty alcohol polyoxyethylene ether phosphate, and deionized water. The % calculation includes the following components OP wax 19.5-32 parts, fatty alcohol polyoxyethylene ether 2.54-9.25 parts, fatty alcohol polyoxyethylene ether phosphate salt 0.45-1.58 parts, deionized water 65-70 parts, heated by the reactor The melting selector is pro...
