Problems solved by technology

However, the current waterproofing agent market has many product specifications, product quality has great defects, and prices are chaotic, which greatly affects the healthy development of the industry.
Among the current waterproofing agent products, some will greatly reduce the strength of mortar and concrete layers; some will greatly delay the construction time; poor durability
In addition, there are some products that use imported raw materials, and the price is high, which is not conducive to promotion

Abstract

The invention discloses a preparation method of an organic / inorganic hybrid impervious dense water-proofing agent applicable to the construction waterproof projects. The preparation method comprises the following steps: firstly, dispersing silica fume and an active organic silicon hydrophobic compound in an organic / inorganic hybrid solution of even system in an emulsifying manner, and then blending the organic / inorganic hybrid solution with other multifunctional compounds to obtain the water-proofing agent. The impervious dense water-proofing agent prepared by the method has the advantages that a waterproof layer structure is denser, and the impervious performance, waterproofness and durability of a project can be enhanced obviously.

Description

technical field [0001] The invention belongs to the field of new chemical building materials, and relates to a preparation method of a high-performance organic-inorganic hybrid anti-seepage compact waterproof agent. Background technique [0002] The construction technology of using new waterproof agent for rigid integrated waterproofing in building waterproofing projects has been more and more applied and promoted. Compared with the current membrane flexible waterproof construction technology, the new waterproof agent used in this technology can form an organic whole with the mortar and concrete layer, thus forming an integral structure with the building, which greatly improves the quality of construction projects and prolongs the life of construction projects ; At the same time, the construction process is greatly simplified, and the cost of waterproofing projects can be reduced by 20%, which is an inevitable trend of building waterproofing in the future. However, the curr...
