Abstract

A lubricant with oxidized polyvinyl wax as main material is manufactured by non-ionizing oxidized polyvinyl wax, negative ionizing surfactant OP-10 or TX-10 or NP-10, then composing modified surfactant said above and non-ionized oxidized polyvinyl wax and silicone, emulsifying to prepare solids content 25% products which is oil-in-water type emulsified products. The lubricant is used as special coating for papermaking and has viscosity<30Mpa.s, and its performance / price rate exceeds imported products.

Description

1. Technical field [0001] The present invention relates to manufacturing. A special lubricant for coating, especially the production process of the lubricant prepared from oxidized polyethylene wax as the main raw material. 2. Background technology [0002] When oxidized polyethylene wax is selected as the main raw material to prepare a special lubricant for papermaking coating, its product performance, in terms of stability, smoothness, gloss, surface strength, ink absorption, printing gloss, etc., is superior to that of traditional lubricants. Special lubricants for papermaking coating, for example, paraffin wax emulsion lubricants formed by emulsification after melting paraffin wax as raw materials; water-mixed liquid lubricants formed by stearate (calcium) Lubricant made by addition reaction and gene reaction with organic acid and unsaturated wax as raw material under the action of initiator; and lubricant obtained by emulsification with silicone oil as raw material, al...
