Flame retardant modified asphalt waterproof paint and production method thereof

Abstract

The invention relates to a flame retardant modified asphalt waterproof paint, which is prepared from the the following raw materials by weight: 50-65 parts of 90# petroleum asphalt; 60-70 parts of water; 22-26 parts of styrene butadiene latex; 4-6 parts of an emulsifier; 2-4 parts of polyvinyl alcohol; 2-5 parts of N-methyl-3-aminopropyl trimethoxy silane; 3-5 parts of a flame retardant; 5-7 partsof polyoxyethylene polyoxypropylene ether; 3-5 parts of triethyl citrate; 0.1-0.5 part of hydrogenated rosin glyceride; 1-3 parts of sodium polyacrylate; and 10-15 parts of modified nano calcium carbonate. The flame retardant modified asphalt waterproof paint prepared by the method provided by the invention has good film compactness and high stability, a waterproof layer formed by the waterproofpaint in a building has large bonding strength with a cement concrete base surface and good waterproof effect, moreover, after modification, the product has substantially improved flame retardance, water tolerance, aging resistance, acid and alkaline resistance and the like.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a flame-retardant modified asphalt waterproof coating and its production [0002] method. Background technique [0003] The waterproof problem of buildings is not only related to people's work and living environment, but also affects the service life of buildings. Building waterproof materials refer to materials that prevent rainwater, groundwater, water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings. Building waterproof coating has the characteristics of simple construction and strong adaptability to complex structures, and is widely used in building construction. Waterproof coatings are mainly used for waterproofing, moisture-proofing and anti-seepage of some structural parts of buildings that may be eroded by water. Therefore, there are certain requirements for the high and low temperature resistance and anti-corrosio...

AI Technical Summary

Problems solved by technology

Although the above-mentioned two documents have modified asphalt to obtain better waterproof coatings, they have not modified the fillers used in the preparation of bitumen waterproof coatings, such as barium sulfate and talcum powder. properties, and unmodified fillers will have obvious disadvantages when filled in various polymers when used in the preparation of coatings: one is that the surface is hydrophilic and oleophobic, and the dispersion in the polymer is poor; the other is that it is compatible with the polymer body Poor binding force, can only play a role in compatibilization

However, the production of water-emulsified asphalt is cumbersome, and the biggest disadvantage is that because it is water-based, its film-forming compactness is poor, so waterproof and aging resistance are poor; and solvent-based asphalt cannot be used indoors due to the presence of a large amount of harmful organic substances.

Moreover, the current water-based asphalt-based waterproof coatings on the market have poor stability, poor alkali resistance and acid resistance, and various technical indicators are difficult to meet the relevant requirements.
