Abstract

The invention discloses a building mortar surface active agent preparation method which includes the process steps: 1) firstly, adding 12-14 parts of sodium carbonate and 80-90 parts of paper pulp waste liquid into a heating container to heat mixture to reach the temperature of 85-95 DEG C, secondly, adding 8-9 parts of calcium lignosulphonate, and heating mixture to reach the temperature of 100-110 DEG C for 30-40 min; 2) adding 3-5 parts of emulsified oil into materials acquired in the step 1), continuing to decoct mixture for 35-45 min, enabling the mixture to enter a closed stirrer, and stirring the materials in the closed stirrer for 20-30 min at the rotation speed of 800-1000r / min; 3) adding 0.8-1.2 parts of sodium alkyl benzene sulfonate and 1.5-2.5 parts of citric acid after the materials acquired in the step 2) are cooled to the normal temperature, and uniformly stirring mixture to obtain colloid liquid products.

Description

technical field [0001] The invention relates to the field of mortar additives, in particular to a method for preparing a construction mortar surfactant. Background technique [0002] Dry powder mortar is widely used in the construction industry and is divided into masonry mortar, plastering mortar, ground mortar and so on. At present, natural sand is generally used as the main component of dry powder mortar, and it is prepared with cement and additives, etc. The cost is relatively high, and the water retention and compressive strength are average. Mortar additive, commonly known as waterproof sand crystal king, also called rock essence, cement surfactant, is a substance that acts on cement to improve the performance of cement mortar. It belongs to the category of concrete admixture, and its main function is to improve the repellency of mortar Water-based, when added to the mortar, it can diffuse the cement particles, reduce the tendency of cement particles to aggregate, a...
