High-molecular composite boundary medium preparation process and use method thereof

Abstract

The invention discloses a high-molecular composite boundary medium preparation process and a use method thereof, and belongs to the field of boundary medium preparation, the high-molecular composite boundary medium preparation process comprises the following steps: adding film-forming magnetic balls, guiding the film-forming magnetic balls to sink and float in a mixed emulsion through a magnetic material in the preparation process, and effectively cutting bubbles in the sinking and floating process, so that the air content in the formed high-molecular composite boundary medium is low, the quality of the high-molecular composite boundary medium is effectively improved, and the high-molecular composite boundary medium can be adsorbed on the surface of the mixed emulsion to form a magnetic chain net; the magnetic chain net can serve as a barrier on the high-molecular composite boundary medium to effectively intercept water vapor of external air from permeating into the high-molecular composite boundary medium, the high-molecular composite boundary medium is effectively protected from being oxidized, and the service life of the high-molecular composite boundary medium is effectively extended; when the high-molecular composite boundary medium is used, the film-forming magnetic balls can form a diaphragm layer on the surface of the boundary medium layer part, and the contact area between the whole boundary medium layer and the outside is reduced, so that the drying speed of a base body is reduced, the cracking rate is reduced, and the using effect is improved.

Description

technical field [0001] The invention relates to the field of media preparation, and more specifically, to a preparation process of polymer composite media and a method for using the same. Background technique [0002] The interface agent is the interface agent. The interface agent treats the surface of the object. The treatment may be physical adsorption or coating, and it is often a physical and chemical effect. The aim is to improve or completely change the physical-technical properties and surface chemical properties of the material surface. [0003] The interface agent has the following characteristics: [0004] 1. Two-way penetration bonding, which produces a radioactive chain anchoring effect to permanently and firmly bond two-way materials together. [0005] 2. It has a high degree of softness, toughness, good air permeability, freeze-thaw resistance, water resistance, aging resistance, non-toxic, tasteless, and pollution-free, and is a green product. [0006] 3. A...

Problems solved by technology

[0008] However, in the prior art, the drying speed of the gypsum base material is faster after using the medium, which causes the gypsum body to crack easily. In addition, in the process of preparing the medium, the mixing of various materials adopts high-speed mechanical agitation. During this process, more air is easily introduced, which makes the obtained medium easy to be oxidized, resulting in a lower service life than the expected life and affecting its quality.
