Description
Patented Get. 16, 1934- Emsmmo. MEDIA AND rnocnss or MANUFACTURING THE SAME Rudolf Kern, O'schatz, Germany, assignor to the firm Chemische Fabrik R. Baumheier Aktiengcsellschaft, Zschollau, near Oschatz, Germany No Drawing. Application August 4, 1931, Serial No. 555,150. In Germany August 6,1930
Claims.
My invention relates to improvements in emulsifying media and the process of manufacturing the same, and more particularly in emulsifying media which are adapted to transform resin,
5 asphalt, tar, bitumen and the like into stable emulsions.
It has heretofore been proposed to emulsify resin with casein as emulsifying medium. Further, it has been proposed to use resin soap as an emulsifying medium for resins.
I have discovered that resin soap or fatty acid soap together with alkaline or ammoniacal casein-"has an energetic emulsifying action on resin, the combined action of tre components largely exceeding the individual action'of the components. I have found that the maximum of the emulsifying action is not immediately obtained, but only after some hours.
In the manufacture of the emulsifying medium the casein is made to swell with an alkaline or ammoniacal solution, and thereafter it is mixed with the soap while kneading at elevated or at ordinary temperature, until the h ghest degree of viscosity is obtained. In a modification of the process the casein is mixed with resin or fatty acid, and thereafter ammonia solution is added. Thereby the soap is formed, and the casein is made to swell. The product is stirred to the .highest degree of viscosity. If from the beginning a larger amount of resin is added than is saponified, the emulsion of the resin is directly obtained.
Example 1.'200 parts of powdered casein are made to swell by slowly passing the same into 800 grammes of a watery ammoniacal solution, 500 parts of a 40% oleic acid soap are added at elevated temperature while kneading the matter, kneading being afterwards continued tw0.hours. The result is a very viscous matter which may be drawn into long threads, and which is ready for use after some time. It is adapted to distribute resin into a very fine watery emulsion.
Example 2. -l00 parts of casein are mixed with 80 parts of powdered resin. While heating and carefully stirring the product ammonia is slowly added, until the matter is completely swollen and saponified.
The number of the drops of a solution of oil of turpentine and resin obtained in the glass pipette of Donnan in the emulsifier solution is not a direct proof for the quality of a technical emulsion. The casein-ammonia-soap emulsifier has its highest quality even if the number of the drops is not at its maximum. But it is most effective in preventing conglomeration O he resin globules, so that the said globules are not collected at the surface and are not molten together or sintered.
I claim:
1. The herein described emulsifying medium, which consists of a mixture of alkaline casein with a fatty acid soap, and which is manufactured by mixing casein swollen by alkali with a resin soap or fatty acid soap, and stirring the mixture'to the highest degree of viscosity.
2. The herein described emulsifying medium, which consists of a mixture of casein ammonia with a fatty acid soap, and which is manufactured by mixing casein ammonia swollen by ammonia with a resin soap or fatty acid soap, and stirring the mixture to the highest degree of viscosity.
3. The process of manufacturing emulsifying media which consists in mixing casein swollen by ammonia with a fatty acid soap, stirring the mixture at elevated temperature between 20 C. and 90 C. to the highest degree of viscosity and then allowing the mixture to stand in order to ripen the same.
4. The process of manufacturing an emulsion of resin which consists in mixing resin and casein, the amountof resin exceeding that necessary for sapom'fication, saponifying a part of the resin by kneading the same with an alkali thereby causing the casein to swell then agitating the mixture to the maximum degree of viscosity and then allowing the mixture to stand in order to ripen the same.
5. The process of manufacturing an emulsion of resin which consists in mixing resin and casein, the amount of resin exceeding that necessary for sapom'fication, saponifying a part of the resin by kneading the same with ammonia thereby causing the casein to swell then agitating the mixture to the maximum degree of viscosity and. then allowing the mixture to stand for several hours.
6. The process of manufacturing an emulsifying medium which consists in adding to casein an alkali to swell the same, then mixing said swollen casein with a soap taken from a group consisting of resin soaps and fatty acid soaps and then stirring the mixture to a high degree of viscosity.
7. The process of manufacturing an emulsifying medium which consists in mixing casein with a soap taken from a group consisting of resin soaps and fatty acid soaps in the presence of an alkali to swell the casein and then stirring the mixture to a high degree of viscosity.
of an ammoniacal solution to swell the casein and thenstirringthemixturetoahighdegreeof viscosity. 7
10. The process of manufactm'ing an emulsitying medium which consists in mixing casein swollen by an alkali with a soap taken from a group consisting of resin soaps and fatty acid soaps, stirring the mixture to the highest degree,
of viscosity and then allowing the mixture to stand in order to ripen the same.
