Problems solved by technology

[0003] However, the use of commonly used mortar plasticizers will cause the mortar strength to shrink, wall tiles to fall off, water resistance to decrease, and contain highly toxic substances such as sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, polypropylene Amides are harmful to the environment and human body, thus limiting the application of mortar plasticizers

Abstract

The invention discloses an efficient poison-free mortar plasticizer and a preparation method thereof and relates to the technical field of mortar plasticizers. The efficient poison-free mortar plasticizer is composed of natural sodium-based soil, talcum powder, carboxymethyl cellulose, silicate, sodium sulfate, sodium nitrite, sodium hydroxide, a surface active agent, humectant, an organic solvent and water. The mortar plasticizer has beneficial workability, not only can obviously improve the adhesive strength of mortar, reduce construction cost and improve the durability of the mortar, but also improves the effects of seepage prevention, moisture prevention and mildewing prevention for the mortar, meanwhile lowers the freezing point of the mortar, improves the freezing resistance of the mortar, does not contain poisonous substances and is environmentally friendly and user-friendly.

Description

technical field [0001] The invention relates to the technical field of mortar plasticizers, in particular to an efficient and non-toxic mortar plasticizer and a preparation method thereof. Background technique [0002] Mortar plasticizer, also known as mortar king and rock essence, is a substance that acts on the cementing material to improve the performance of cement mortar. It mainly improves the workability and water retention of mortar, improves the efficiency of laying and plastering, and reduces Eliminate ground ash, save cement and lime paste. In the mortar, it mainly plays the role of diffusing cement, emulsifying and foaming, etc., and can overcome common problems such as shelling and cracking. It is best used as a primer or surface layer on the ground of inflated concrete and ordinary concrete. The mortar in masonry has a high degree of fullness. After hardening, it has the functions of antifreeze, water reduction, seepage prevention, durability, crack resistance,...
