Embodiment 1

[0019] The present invention comprises the following steps:

[0020] A. First heat the base asphalt to 120°C, then add 5% SBR asphalt modifier and use a high-speed dispersing and shearing emulsifier to fully insulate and stir for 2 hours;

[0021] B. After lowering the temperature to 80°C, add 5% OP-10 emulsifier and stir well for 2 hours to obtain the base material;

[0022] C. The temperature of the base material is kept at 80°C, and it is mixed with water at the same temperature at a ratio of 1:1 using a high-speed dispersing shear emulsifier for 2 hours, and finally the finished product is obtained.

Embodiment 2

[0024] The present invention comprises the following steps:

[0025] A. First heat the base asphalt to 120°C, then add 15% SBR asphalt modifier and use a high-speed dispersing and shearing emulsifier to fully insulate and stir for 2.5 hours;

[0026] B. After lowering the temperature to 100°C, add 10% OP-1 emulsifier and stir thoroughly for 2.5 hours to obtain the base material;

[0027] C. The temperature of the base material is kept at 93°C, and it is mixed with water at the same temperature at a ratio of 1:1 using a high-speed dispersing shear emulsifier for 5 hours, and finally the finished product is obtained.

Embodiment 3

[0029] The present invention comprises the following steps:

[0030] A. First heat the base asphalt to 120°C, then add 20% SBR asphalt modifier and use a high-speed dispersing and shearing emulsifier to fully insulate and stir for 5 hours;

[0031] B. After the temperature is lowered to 110°C, add 15% carboxylate emulsifier (anionic emulsifier) ​​and fully stir for 3 hours to obtain the base material;

[0032] C. The temperature of the base material is kept at 100°C, and it is mixed with water at the same temperature at a ratio of 1:1 using a high-speed dispersing shear emulsifier for 5 hours, and finally the finished product is obtained.

Abstract

The invention relates to a modified emulsified asphalt waterproof paint preparation method. The method includes: heating matrix asphalt to 120-200 DEG C, adding 5%-20% of an asphalt modifier, preserving heat and well stirring for 2-5h; cooling to 80-110 DEG C, adding 5%-15% of an asphalt emulsifier, and stirring for 2-3h to obtain a matrix material; keeping the temperature of the matrix material at 80-100 DEG C, and stirring the matrix material along with water for 2-5h to finally obtain a finished product, wherein the matrix material and the water are identical in temperature, and a ratio of the matrix material to the water is 1:1. According to the modified emulsified asphalt waterproof paint preparation method, the matrix asphalt is modified and emulsified in one time to form the product, high production efficiency and low cost are realized, and the product is high in stability.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a preparation method of a modified emulsified asphalt waterproof coating. Background technique [0002] Asphalt is a brown or dark brown organic gelling material, which is an indispensable material in civil engineering construction. It is widely used in construction, highway, bridge and other projects. Asphalt waterproof coating is a solvent-based or water-emulsion waterproof coating based on asphalt. It has the advantages of weather resistance, acid and alkali resistance, long service life, high tensile strength, strong self-healing property and high elongation. [0003] With the rapid development of highway business and waterproof business, it also promotes the development of modified emulsified asphalt. Modified emulsified asphalt waterproof coating is a new type of asphalt waterproof coating. It changes the characteristics of traditional asphalt that are brittle at low temperature ...
