Problems solved by technology

However, water-based products must introduce hydrophilic groups or surfactants to achieve the hydrophilic effect. The use of a large number of surfactants will inevitably bring about unavoidable side effects, that is, the generation of foam, and the existence of foam will affect the production and use...

Abstract

The invention discloses a preparation method of a mineral oil defoaming agent, comprising the following steps: adding mineral oil to a reaction container; adding wax, white carbon black, an emulsifying agent and oleic acid in sequence when dispersing at a high speed; after finishing adding, dispersing until the system is basically and uniformly dispersed at a high speed; turning to a colloid grinder and grinding and dispersing for 4-6 times; checking; and after the material is qualified, discharging the material. In the preparation method of a mineral oil defoaming agent in the invention, a proper variety of wax or modified wax is selected so that the mineral oil defoaming agent has perfect dispersing and defoaming effects and storage stability; the prepared mineral oil defoaming agent is a novel water defoaming agent, and has the characteristics of environmental protection, safety, excellent performance, and the like; the preparation method perfects the sorts of the products in the domestic market; and the preparation method has a simple manufacturing process and is easy to produce in a large scale.

Description

technical field [0001] The invention belongs to the field of fine chemicals, and in particular relates to a preparation method of a mineral oil defoamer. Background technique [0002] Due to the aggravation of environmental protection issues, people's awareness of environmental protection is also increasing, and the additives needed in industries such as textiles, leather, packaging, coatings, and inks are becoming more and more water-based. However, water-based products must introduce hydrophilic groups or surfactants to achieve the hydrophilic effect. The use of a large number of surfactants will inevitably bring about unavoidable side effects, that is, the generation of foam, and the existence of foam will affect the production and use of products. And post-processing, etc. have brought serious harm. Therefore, water-based products have higher defoaming requirements than oil-based products. In order to meet this requirement, more and more defoamers have come out, but the...
