Abstract
The invention discloses a strong permeability waterproof agent and a preparation method thereof. The strong permeability waterproof agent comprises the following raw materials by following mass fraction: 1.8-2.5 parts of organosilicon polymer, 0.1-0.3 parts of osmotic agent, 0.1-0.3 parts of levelling agent, 0.1-0.3 parts of antifoaming agent, 0.1-0.3 parts of dispersing agent and 96-98 parts of cosolvent. The waterproof agent is prepared by adding the ingredients in a container one by one and then stirring, controlling the temperature and filtering under normal pressure condition. The strong permeability waterproof agent has the advantages of production technology simplification, prevention of high temperature / high pressure synthesis risk, and no three wastes generation of composition; and has the beneficial effects of strong high-temperature resistance, strong permeability, fast drying and no change of color of original product. The strong permeability waterproof agent can be widely used for moisture and mildew resistant treatment before interior decoration, and used for water repellent treatment in stone industry, woodwork and textile industry, and is especially suitable for rapid construction under special environment.
Description
Technical field [0001] The invention relates to a waterproofing agent, in particular to a strong penetrating waterproofing agent and a preparation method thereof. Background technique [0002] 1 Silicone [0003] Organosilicon, or organosilicon compound, refers to a compound that contains Si-O bonds and at least one organic group is directly connected to the silicon atom. It is customary to use oxygen, sulfur, nitrogen, etc. to connect the organic group to the silicon atom. The connected compounds are also regarded as organosilicon compounds. Among them, the polysiloxane composed of silicon-oxygen bond (-Si-0-Si-) is the largest, most researched and most widely used type of organosilicon compounds, accounting for more than 90% of the total amount. . [0004] The basic structural unit of organic silicon products is composed of silicon-oxygen chain links, and the side chains are connected to various other organic groups through silicon atoms. Therefore, the structure of organic sil...
