Problems solved by technology

[0004] The traditional drying cylinder stripping agent is generally a low-content emulsion. The product is easy to separate after a long time, causing the nozzle to be blocked, resulting in poor use effect. The main component is alkane oil with different carbon chain structure and different purity.
Due to the strong hydrophobicity of alkane oil, the oil remaining in the final paper product has an impact on the quality of the paper product, which reduces the ability of the paper product to absorb water

Embodiment 1

[0023] Put 500 parts (parts by weight, the same below) of 26# white oil into a dry and clean 1000L high-speed mixer, keep the speed at 1000 rpm, then add 200 parts of tall oil fatty acid and 100 parts of tall oil to the high-speed mixer ; Stir for 10 minutes. Add 80 parts of Span 80 and Tween 80 to the above system, and stir for 15 minutes. Finally, 20 parts of polyethylene glycol 600 was added and stirred for 5 minutes. Then add 100 parts of polyethylene glycol 400 dioleate and stir for 10 minutes. After the sampling test is qualified, the material is discharged and packaged.

Embodiment 2

[0025] Put 200 parts of 32# white oil into a dry and clean 1000L high-speed mixer, keep the speed at 1000 rpm, then add 150 parts of tall oil fatty acid and 50 parts of tall oil to the high-speed mixer, and stir for 20 minutes. Add 400 parts of alkylphenol polyoxyethylene ether (10) and Tween 80 to the above system, and stir for 15 minutes. Finally, 100 parts of polyethylene glycol 400 was added and stirred for 5 minutes. Then add 100 parts of polyethylene glycol 400 monooleate and stir for 10 minutes. After the sampling test is qualified, the material is discharged and packaged.

Embodiment 3

[0027] Put 400 parts of 32# white oil into a dry and clean 1000L high-speed mixer, keep the speed at 1000 rpm, then add 400 parts of oleic acid hydroxyethylimidazoline into the high-speed mixer, and stir for 15 minutes. Add 180 parts of polyethylene glycol 400 monooleate and alkylphenol polyoxyethylene ether (10) to the above system, and stir for 10 minutes. Finally 20 parts of polyethylene glycol 400 was added and stirred for 15 minutes. After the sampling test is qualified, the material is discharged and packaged.

Abstract

The invention relates to a drying cylinder stripping agent for papermaking and a preparation method thereof. The drying cylinder stripping agent comprises, by weight, 15-80 parts of alkane oil, 20-60parts of an oiliness agent, 5-50 parts of an emulsifier and 2-15 parts of an activator, wherein the oiliness agent is one or more of tall oil fatty acid, tall oil, erucic acid and hydroxyethyl imidazoline oleate, and the emulsifier is one or more of triethanolamine oleate soap, Tween 80, span 80, polyethylene glycol dioleate, polyethylene glycol monooleate and alkylphenol ethoxylates. The drying cylinder stripping agent can thoroughly solve the problem of cylinder sticking in papermaking, keeps a system clean, allows paper sheets to be free of oil spots, and achieves good stripping, lubricating and brightening effects.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and relates to a drying cylinder release agent for papermaking and a preparation method thereof. Background technique [0002] With the decrease of high-quality pulp, more and more recycled pulp is used in papermaking. Some pulps have short fibers and many impurities, while recycled pulp has more colloidal substances. These impurities and colloidal substances are related to the dryer. In addition, due to the extensive use of non-wood fibers, the increase in the amount of papermaking chemicals, especially the increasing proportion of secondary fibers used in papermaking, sticking to cylinders and paper powder falling have become a problem in the papermaking process. It is a relatively common phenomenon, resulting in the occurrence of roughening of the paper surface, paper breakage, paper dusting, etc., which seriously affect the normal operation of the paper and the quality of the paper, which...
