preparation example Construction

[0042] Another embodiment of the present invention provides a method for preparing the above cleaning agent, which specifically includes the following steps:

[0043] According to the raw material formula of the cleaning agent, the emulsifier and the water-soluble polymer are added to the water, and the emulsifier and the water-soluble polymer are stirred until the emulsifier and the water-soluble polymer are dissolved to obtain the first mixture;

[0044] Adding a pH adjuster to the first mixture, and continuing to stir until uniformly mixed, to obtain a second mixture;

[0045] Add an organic solvent into the second mixture and mix well to obtain a cleaning agent.

[0046] In this way, strictly controlling the order in which each component is added to the water can ensure that the components are fully dissolved and mixed with each other, so as to avoid affecting the use of the cleaning agent due to insoluble or insoluble components.

[0047] It can be understood that the mi...

Embodiment 1

[0053] 1) A formula of cleaning agent: 35 parts of water + 30 parts of organic solvent + 3 parts of emulsifier + 0.8 parts of water-soluble polymer + 6 parts of pH regulator.

[0054] 2) Preparation method:

[0055] Accurately weigh 35.0 kg of tap water and put it into the stainless steel dispersion tank. Under the condition of stirring (butterfly stirring), weigh 3.0 kg of emulsifier Tween-20 and add it to the dispersion tank, and weigh 0.8 kg of water-soluble polymer PVA-1788 Add to the dispersion tank, stir at low speed until the emulsifier and high molecular polymer are completely dissolved, then add 6.0 kg of pH regulator sodium carbonate, stir at low speed to dissolve, add 30.0 kg of ethyl ester organic solvent, stir well and pack for later use.

[0056] The obtained cleaning agent is a translucent viscous liquid, and the measured viscosity of the cleaning agent is 11000 centipoise and the pH value is 10.8.

Embodiment 2

[0058] 1) A formula of cleaning agent: 50 parts of water + 25 parts of organic solvent + 3.5 parts of emulsifier + 0.5 parts of water-soluble polymer + 3 parts of pH regulator.

[0059] 2) Preparation method:

[0060] Accurately weigh 50.0 kg of tap water and put it into the stainless steel dispersing tank. Under the condition of stirring, weigh 3.5 kg of emulsifier isomerized thirteen polyoxyethylene ether (E-1320) and add it to the dispersing tank. Add 0.5 kg of acrylamide to the dispersing tank, stir at low speed until the emulsifier and high molecular polymer are completely dissolved, then add 3.0 kg of sodium hydroxide pH regulator, stir at low speed to dissolve, add 25.0 kg of acetone organic solvent, stir well and pack for later use.

[0061] The obtained cleaning agent is a translucent viscous liquid, and the measured viscosity of the cleaning agent is 10500 centipoise and the pH value is 11.6.

Abstract

The invention relates to a cleaning agent and a preparation method thereof. The cleaning agent is mainly made of the following raw materials by weight: 10 to 30 parts by weight of organic solvent, 3 to 5 parts of emulsifier, 0.5 to 3 parts of water-soluble polymer, 3 to 10 parts of pH adjuster and 20 to 52 parts of water. The organic solvent can be miscible with water. This cleaning agent has strong peeling ability of polymer scale and high cleaning efficiency. It can quickly and thoroughly clean synthetic resin reactors. It is especially suitable for cleaning resin storage tanks made of stainless steel synthetic resin reactors, fiberglass reinforced plastics, plastics and other materials.

Description

technical field [0001] The invention relates to the technical field of cleaning agents, in particular to a cleaning agent suitable for cleaning synthetic resin reactors and a preparation method thereof. Background technique [0002] Synthetic resin is a high molecular polymer formed by chemical reaction. The reaction process is usually carried out in a reactor, and the reactor generally needs to be heated during the resin synthesis process. The heating of the reactor is through the outer wall coil or jacket of the reactor, and the heat is transferred to the reactor through the reactor wall, so the temperature of the reactor wall is usually higher than that of the reactor, so that the polymer is formed on the reactor wall. The speed is faster than that in the kettle, and some polymers are easy to adhere to the wall of the reactor. With the increase of the use time of the reactor and the increase of the reaction temperature, the polymer attached to the wall of the reactor wil...
