Problems solved by technology

Mineral oil stripper not only has poor stripping effect during use, but also easily produces oil spots, oily smell, and yellowing
In addition, the body-type stripper needs to self-emulsify quickly during use. If the self-emulsification effect is poor, the nozzle will continue to be blocked, which will affect production efficiency.
Emulsion-type peeling agents also have the problem of poor storage stability

Embodiment 1

[0028] Add 30g of pentaerythritol oleate, 6g of EL80 (castor oil polyoxyethylene ether 80), and 15g of propylene glycol into the reaction kettle in sequence, and turn on the stirring speed at 100rpm until a uniform solution is formed. Increase the stirring speed to 800 rpm, slowly add 49 g of deionized water, and stir until a uniform white emulsion is formed. Then, the white emulsion was ultrasonically emulsified at 50° C. for 1 hour to form a microemulsion with a particle size of 10-200 nm, and the appearance was a transparent bluish uniform liquid.

Embodiment 2

[0030] Add 30g of glycerin trioleate, 6g of AEO-20 (fatty alcohol polyoxyethylene ether), and 15g of glycerin into the reaction kettle in sequence, and turn on the stirring speed at 100rpm until a uniform solution is formed. Increase the stirring speed to 800 rpm, slowly add 49 g of deionized water, and stir until a uniform white emulsion is formed. Then, the white emulsion was ultrasonically emulsified at 50° C. for 1 hour to form a microemulsion with a particle size of 10-200 nm, and the appearance was a transparent bluish uniform liquid.

Embodiment 3

[0032] Add 20g triglyceride oleate, 4g AEO-20 (fatty alcohol polyoxyethylene ether), and 5g dipropylene glycol into the reaction kettle in sequence, and turn on the stirring speed at 100rpm until a uniform solution is formed. Increase the stirring speed to 800 rpm, slowly add 71 g of deionized water, and stir until a uniform white emulsion is formed. Then the white emulsion is ultrasonically emulsified at 50° C. for 1 hour to form a microemulsion with a particle size of 10-200 nm, and the appearance is a transparent bluish homogeneous liquid.

Abstract

The invention discloses a polyol ester-aqueous microemulsion type drying cylinder stripping agent, which is characterized by comprising 10-50% of polyol ester, 1-10% of an emulsifier, 2-20% of a solubilizer and the balance of deionized water, the stripping agent is a microemulsion, and the particle size range of the microemulsion is 10-200 nm. The stripping agent is a water-based microemulsion, can be mixed and dissolved with water in any ratio, is good in compatibility with a cylinder adhesive, has good spreadability on a drying cylinder, is good in stripping effect, is free of peculiar smell, and is green, environment-friendly and degradable.

Description

technical field [0001] The invention belongs to the technical field of pulping and papermaking, and in particular relates to an emulsion type drying cylinder release agent. Background technique [0002] In the papermaking process, the peeling degree of the paper directly determines whether the production can proceed normally. Due to the increase in the speed of the paper machine, the use of a large number of secondary fibers, and the increase in the amount of papermaking chemicals, it is becoming more and more difficult to peel off the paper, and the requirements for the dryer stripping agent are getting higher and higher. [0003] The main component of traditional drying cylinder stripper is mineral oil, which is divided into bulk type (oily) and emulsion type. Mineral oil stripper not only has poor stripping effect during use, but also easily produces oil spots, oily smell, and yellowing. In addition, the bulk-type stripping agent needs to self-emulsify quickly during us...
