Abstract

The invention discloses a controllable and permeable nano-silicon ion protective agent and a preparation method thereof. The protective agent is prepared from the following raw materials in parts by weight: 30-50 parts of sodium silicate, 5-20 parts of potassium silicate, silicon 1-5 parts of lithium oxide, 20-30 parts of organosilicate, 2-6 parts of penetrant, 0.5-2 parts of dispersant, 0.2-1 part of calcium ion blocking agent, 0.1-1 part of gel retarder, stabilizer 0.1-0.5 part, coagulant 0.1-0.3 part, coagulation accelerator 0.1-0.3 part, antifreeze 0.2-0.5 part, deionized water 100-120 part. Preparation method: according to the proportion, the above-mentioned raw materials are sequentially introduced into a stirring tank, and after stirring for 30-50min, the product is obtained by filtration and precipitation. The protective agent can adjust the reaction speed according to the density of concrete, and also has multiple effects such as crack healing, acid and alkali resistance, corrosion resistance, impermeability improvement, and weathering resistance.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a controllable and permeable nano-silicon ion protective agent and a preparation method thereof. Background technique [0002] The water-based permeable inorganic waterproofing agent has the characteristics of permeability and can seal the capillary channels and cracks of cement mortar and concrete. The patent with publication number CN101619203A discloses a water-based penetrating crystalline waterproofing agent and a preparation method thereof. The method integrates inorganic silicon and organic silicon, and belongs to a neutral waterproofing agent, but the reaction speed is uncontrollable, and it is easily caused by the compaction of concrete. Different degrees cause use failure. The patent with publication number CN106904928A discloses a water-based osmotic crystalline waterproof coating whose reaction speed is regulated by adjusting sodium borate and ...
