Description
Technical Field
The invention relates to a stearate paste water-based isolating agent, in particular to a zinc stearate and magnesium stearate compound paste water-based isolating agent.
Background
In the production process of rubber products, the rubber compound is easy to adhere to cause production and processing difficulties, so that the film release agent is used for blocking the mutual adhesion of films. The existing release agent product has four forms of paste, liquid, powder and suspension, wherein the powder release agent has more complex components, and the imported powder release agent has good release effect, small influence on the performance of sizing materials and high price. And the domestic powdery isolating agent has low price but uneven quality, and generally has the problems of poor isolating effect, indissolvable property, foaming, precipitation, low drying speed, environment pollution caused by flying and the like. However, although paste and liquid release agents are generally low in price, they can be dispersed in water only by heating, and the release effect is poor, and the influence on the performance of the sizing material is great; the film surface adopting the 2 release agents is smooth, and the film can slide easily after hanging, so that production stagnation is caused. In addition, although the suspension release agent is blended with water in a certain proportion and is relatively low in price when in use, powder is easy to adhere to the surface of a film, so that white powder is polluted, and if the attachments are too much, certain properties of the sizing material can be influenced.
At present, the isolating agent widely used in the market is a paste water-based isolating agent and an aqueous suspension dispersion liquid, but the paste isolating agent has the problem of troublesome dilution, and the aqueous suspension dispersion liquid is easy to generate sedimentation phenomenon when being stored.
Therefore, how to provide a stearate paste water-based isolating agent which is low in cost, simple and convenient to prepare and easy to dilute and store is a technical problem to be solved by the person skilled in the art.

Since zinc stearate and magnesium stearate are hardly soluble in water, the wetting and dispersing agent functions to wet zinc stearate and magnesium stearate with water and disperse them in water; the magnesium stearate is light and has the density close to that of water, and has the thickening and thixotropic effects in water, and the release agent prepared by compounding the magnesium stearate and zinc stearate can greatly improve the stability of the release agent after dilution in application and improve the isolation effect in rubber; the thixotropic auxiliary agent can enable the release agent to form paste after thickening, and is helpful for improving the stability of the release agent after dilution.
Optionally, the wetting dispersant is one or more of isomeric tridecyl alcohol polyoxyethylene ether, C16-18 fatty alcohol polyoxyethylene, polyoxyethylene sorbitan monostearate, polyoxyethylene sorbitan monooleate, sodium dodecyl sulfate, sodium dodecyl benzene sulfonate, fatty alcohol polyoxyethylene ether AEO-9 and fatty alcohol polyoxyethylene ether AEO-7.
Optionally, the defoamer is one of modified polydimethylsiloxane, higher phosphate or modified polyether.
Optionally, the thixotropic additive is one of methylcellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, alkali-swelling polyacrylic acid and associated polyurethane.
The invention also claims a preparation method of the stearate paste water-based isolating agent, which specifically comprises the following steps:
respectively weighing the raw materials according to the parts; then adding wetting dispersant and defoamer into water while stirring; and adding powder zinc stearate and powder magnesium stearate after the powder zinc stearate and the powder magnesium stearate are uniformly dispersed, adding a thixotropic auxiliary agent after stirring, and stopping stirring after the system is slowly thickened to form a paste, thus obtaining the stearate paste water-based insulating agent.
Optionally, adding wetting dispersant and defoamer, wherein the stirring speed is 200-400r/min, and the stirring time is 5-10min; the stirring speed is 800-1500r/min and the stirring time is 10-25min when the powder zinc stearate and the powder magnesium stearate are added.
The invention also claims the application of the stearate paste water-based isolating agent in the preparation of sizing materials.
Specifically, the stearate paste water-based isolating agent is used in the operation production processes of plastication, mixing, tabletting and the like of raw rubber and sizing materials.
When in use, the stearate paste water-based isolating agent and water are diluted according to a certain proportion to form stearate isolating liquid with a certain concentration, and the stearate paste is dispersed in the water uniformly by gentle stirring, so that the phenomenon of precipitation or layering does not occur in 90 days.
And the compounding of zinc stearate and magnesium stearate not only improves the stability of the isolating agent after dilution, but also improves the isolating effect. Because magnesium stearate has a certain thickening effect, is light in weight and has a density which is closer to that of water, and the stability after dilution when being singly used is greatly improved by compounding zinc stearate.
Compared with the prior art, the stearate paste water-based isolating agent and the preparation method thereof provided by the invention have the following excellent effects:
