Two-component rubber modified asphalt waterproof coating material, preparation method and applications

Abstract

The invention discloses a two-component rubber modified asphalt waterproof coating material, a preparation method and applications, wherein the two-component rubber modified asphalt waterproof coatingmaterial comprises a first component and a second component according to a mass ratio of 1:(0.1-1.0), the first component is prepared by mixing the following components by mass: 25.8-56% of asphalt,6-15.4% of rubber, 6-24.5% of an asphalt regeneration agent, 0.8-4.0% of an emulsifier, 0.03-5.0% of a stabilizer, 0 -5.0% of other auxiliary agents, and the balance of water, the sum of the mass percentages of the asphalt and the asphalt regeneration agent is 46-63%, and the second component is one or a plurality of materials selected from active fillers and inert fillers. According to the present invention, by using the asphalt regeneration agent, the added rubber can be fused with the asphalt so as not to cause segregation phenomenon, and the asphalt regeneration can greatly reduce the hightemperature viscosity of the modified asphalt, such that the emulsification difficulty of the modified asphalt with the high rubber ratio can be lowered.

Description

technical field [0001] The invention relates to the technical field of asphalt processing, in particular to a two-component rubber-modified asphalt waterproof coating, its preparation method and application. Background technique [0002] Waterproof coatings are mainly used for sealing and waterproofing of large areas and detailed nodes of buildings. The waterproof coating is brushed or sprayed on the base surface, and after curing, it forms a waterproof coating film with good integrity and no seams, which has good adhesion and sealing to the base surface. However, the application of waterproof coatings often requires multiple layers of thin coatings to achieve the required thickness of the waterproof layer. Due to the slow drying speed of waterproof coatings, for example, when applying emulsion-type waterproof coatings, it is necessary to wait for the previous layer of waterproof coating to dry before proceeding to the next layer of waterproof coating. Construction and brus...

Problems solved by technology

However, the application of waterproof coatings often requires multiple layers of thin coatings to achieve the required thickness of the waterproof layer. Due to the slow drying speed of waterproof coatings, for example, when applying emulsion-type waterproof coatings, it is necessary to wait for the previous layer of waterproof coating to dry before proceeding to the next layer of waterproof coating. Construction and brushing, not only the construction efficiency is low, but also the time interval between multiple coats is long, which is easy to cause delamination between coats, resulting in irreparable waterproof failure, especially in rainy weather, when the paint is not dry When soaked in rainwater, it is easy to cause milk regurgitation, resulting in damage to the quality of the paint and loss of waterproof effect

[0003] Another example is the American Henry Company's -Wet Patch TM Brand roof leakage repair products, this kind of sealing products use low-volatility organic solvents, the drying speed is extremely slow, the drying time is very long, it often takes more than two weeks to dry, and the base surface is wet It cannot be constructed. The main components of this product are asphalt and fiber. After drying, the sealing layer has poor elasticity and is not durable enough.
