Abstract

The invention discloses a reinforced and soundproof building waterproofing agent, and a preparation method and application thereof. The reinforced and soundpoof building waterproofing agent comprisesthe following components in parts by mass: 24 to 36 parts of an acrylate polymer emulsion, 6.5 to 10.5 parts of biomass superfine fiber powder, 7 to 15 parts of a carbon material, 8 to 12 parts of a silicon-containing material, 15 to 25 parts of fluffy high-strength resin and 16.5 to 54.5 parts of a solvent. According to the application of the reinforced and soundproof building waterproofing agent, the reinforced and soundproof building waterproofing agent is arranged on concrete, wherein the contact angle between the concrete and water is 159 degrees, and noise is reduced by about 10.5 dB. The reinforced and soundproof building waterproofing agent provided by the invention adopts environmentally-friendly raw materials, especially the biomass superfine powder taken from plants, so the costis reduced, and the safety of the building waterproofing agent is further improved.

Description

technical field [0001] The invention belongs to the technical field of waterproofing agents, and in particular relates to a reinforced and sound-insulating building waterproofing agent and a preparation method thereof. Background technique [0002] With the development of my country's infrastructure projects, the waterproof effect has become an important issue in construction. At present, there are various types of waterproofing agents, which can be roughly divided into three categories: inorganic systems, organic systems, and mixture systems, but there are still certain deficiencies in various types of waterproofing agents. For example, some waterproofing agents can only be sprayed or brushed, and cannot be used as concrete admixtures; some waterproofing agents contain more synthetic ingredients, which are not environmentally friendly; most waterproofing agents do not have additional functions, etc. [0003] Therefore, the development of a building waterproofing agent base...
