Abstract

The invention discloses a stripping agent with complex formulation of mineral oil and an emulsifying agent for a drying cylinder. The stripping agent comprises mineral oil, the emulsifying agent and water. The mass ratio of the mineral oil to the emulsifying agent is 9-10:1, and the mass ratio of the total mass of the mineral oil and the emulsifying agent to water is 1:2-4. An externally spraying form is used for the stripping agent for the drying cylinder, so that a lubricating layer is formed on the contact interface of the drying cylinder and paper, breakage of drying parts is reduced, and smoothness, glossiness and other performance indices of paper sheets are greatly improved; at the same time, the drying cylinder and a drying net are protected, service life of the drying cylinder and the drying net is prolonged, production efficiency and product quality of a paper machine are improved, and the problem that overall performance is not ideal in the prior art is overcome.

Description

technical field [0001] The invention belongs to the field of auxiliary agents and additives in the papermaking industry, and in particular relates to a drying cylinder stripping agent compounded with mineral oil and an emulsifier and a preparation method thereof. The stripping agent is widely used in the processing and manufacturing process of household paper. Background technique [0002] With the decrease of high-quality pulp and the increase of the amount of paper-making chemical additives, especially the increasing proportion of secondary fibers used in papermaking, more and more inferior pulps are used in papermaking, some of which have short fibers, many impurities and components Complicated, there are more colloidal substances in the recycled pulp, and these impurities and colloidal substances have a greater bonding force with the drying cylinder, causing sticking cylinders, which has become a common phenomenon in the papermaking process. However, such as paper roughe...
