Embodiment 1

[0032] take C 14 -C16 100 parts of alcohol, 50 parts of solid paraffin, the above raw materials were mixed and melted, stirred and heated to 70°C to obtain the mixture (1). Take 1 part of polyether (M is dodecyl, x=60, y=0) and 0.5 part of APG and add it to 200 parts of water at 80°C to obtain the mixture (2). Slowly add the mixture (1) to the mixture (2), then use a high-shear device, and dilute it with water to an emulsion with a concentration of 30%, and finally add a thickener polymethacrylate to adjust its viscosity to 286mPa·s. Can. Example 2:

Embodiment 2

[0033] take C 18 100 parts of alcohol, 40 parts of solid paraffin, the above raw materials were mixed and melted, stirred and heated to 90°C to obtain the mixture (1). Take 2 parts of polyether (M is n-octyl, x=40, y=0) and 2.3 parts of APG and add them to 250 parts of water at 70°C to obtain the mixture (2). Slowly add the mixture (1) to the mixture (2), then use a high-shear device, and dilute it with water to an emulsion with a concentration of 25%, and finally add a thickener polymethacrylate to adjust its viscosity to 275mPa·s. Can.

Embodiment 3

[0035] take C 24 100 parts of alcohol, 70 parts of solid paraffin, the above raw materials were mixed and melted, stirred and heated to 90°C to obtain the mixture (1). Add 2.5 parts of polyether (M is n-hexyl, x=90, y=30) and 1 part of APG to 300 parts of water at 90°C to obtain mixture (2). Slowly add the mixture (1) to the mixture (2), then use a high-shear device, and dilute it with water to an emulsion with a concentration of 30%, and finally add a thickener polymethacrylate to adjust its viscosity to 302mPa·s. Can.

Abstract

A natural high class fatty alcohol emulsion and a preparation method thereof belong to the technical field of fine chemical preparation. The natural high class fatty alcohol emulsion is characterized by comprising natural high class fatty alcohol, paraffin, polyether, alkyl polyglucoside (APG for short), thickening agent and water. The preparation method comprises the following steps: A. mixing natural high class fatty alcohol and paraffin in proportion, heating to 70-90 DEG C to obtain mixture (1); B. dissolving polyether and APG in hot water of 70 DEG C to obtain mixture (2); C. adding mixture (1) slowly into mixture (2), and then using an exorbitant shearing device to further emulsify to obtain a crude emulsion; D. supplementing corresponding water quantity to dilute into the required concentration; and E. using the thickening agent to adjust the viscosity of the product to 250-400mPa.s to obtain the natural high class fatty alcohol emulsion. The prepared natural high class fatty alcohol emulsion has good degasification performance in paper-dipping procedure of paper-making and excellent usage in paper-making industry.

Description

technical field [0001] The invention relates to a natural higher fatty alcohol emulsion and a preparation method thereof. Higher fatty alcohol emulsion can be used in the preparation of cosmetics, and can be used as a defoamer, showing better defoaming performance in some foaming systems. Since the defoamer belongs to fine chemical additives, the present invention belongs to the technical field of fine chemical preparations. Background technique [0002] Bubbles and foam are common phenomena in life and production. The so-called air bubbles refer to a group of insoluble gases existing in a liquid or solid, or existing in independent air groups surrounded by their thin films. The accumulated state in which many air bubbles are gathered together and separated from each other by a thin film is called foam. In general, pure water and pure surfactants do not foam. However, in the presence of surfactants in the solution, it is easy to generate foam. After the bubble is formed,...
