Definitions
- the present invention relates to air entraining agents for concrete and mortar mixtures.
- resin soaps which are derivatives of abietic acid, dextropimaric acid, levopimaric acid, as well as derivatives thereof, e.g. Maleic acid adducts to be used as air entrainers.
- a further disadvantage of these resin soap solutions is their sensitivity to water hardness, that is, their tendency to form more or less insoluble salts, especially Ca 2+ salts, which precipitate out of the aqueous solution before use.
- Resin rosin resin soaps behave much better in this regard than rosin soaps based on other raw materials. In recent years, however, these resins are scarce and difficult to obtain.
- these requirements are met by introducing 3 H groups into the abietic acid skeleton in addition to the carboxyl groups S0.
- This can be carried out, for example, by known processes, such as direct sulfonation with SO 3 or sulfonation of terminal double bonds with KHSO 3 and peroxides or KNO 3 , with only the terminal double bonds of dextropimaric acid or the double bonds of levopimaric acid and / or or abietic acid.
- a preferred embodiment of the present invention to introduce sulfonic acid groups is as follows:
- the resin is first maleiniert.
- a solution of one or more aminosulfonic acids in a solution of, on the one hand, aminoalcohols, such as, for example, aminopropanol, aminobutanol, or otherwise monohydric or polyhydric alcohols, for example propanol, butanol or ethylene glycol, as well as mixtures thereof under such reaction conditions is added both the amino groups of the aminoalcohol and the amino groups of the aminosulphonic acid open the anhydride ring of the MSA adduct and form amides or esters.
- aminoalcohols such as, for example, aminopropanol, aminobutanol, or otherwise monohydric or polyhydric alcohols, for example propanol, butanol or ethylene glycol, as well as mixtures thereof under such reaction conditions is added both the amino groups of the aminoalcohol and the amino groups of the aminosulphonic acid open the
- balsam resin consists of dextropimaric acid, which has a terminal double bond. It is not accessible to malting and thus of little effectiveness. By sulfonation, the effectiveness can be increased.
- Example 1 has both a higher proportion of air pores less than 300 .mu.m and a better stability of the air voids compared to the product of Example 3 and is significantly better than Comparative Example A. With respect to the hardness of hard water, Examples 1, 2 and 3 show a significant improvement over Comparative Examples A and B.
