preparation example 1

[0054] A kind of modified emulsified asphalt, its preparation steps are as follows:

[0055] The emulsified asphalt and modified liquid are in a weight ratio of 1:0.3, under the condition of pH 4, vacuumize, heat to 100°C, and stir at a speed of 2500r / min for 20min to prepare modified emulsified asphalt;

[0056] The modified liquid is composed of modified colloid and modified filler in a weight ratio of 1:0.05;

[0057] The modified colloid is composed of hyperbranched polyamide resin, starch and tributyl phosphate in a weight ratio of 1:0.3:0.01;

[0058]The modified filler is nano silica powder.

preparation example 2

[0060] A modified emulsified asphalt, the difference from Preparation Example 1 is that the emulsified asphalt and modified liquid are in a weight ratio of 1:0.3, under the condition of pH 5, vacuumize, and heat to 110°C, at 2750r / min The modified emulsified asphalt can be prepared by stirring at a constant speed for 25 minutes.

preparation example 3

[0062] A modified emulsified asphalt, the difference from Preparation Example 1 is that the emulsified asphalt and the modified liquid are in a weight ratio of 1:0.3, under the condition of pH 6, vacuumize, and heat to 120°C, at 2750r / min The modified emulsified asphalt can be prepared by stirring at a constant speed for 30 minutes.

Abstract

The application relates to a waterproof and anti-seepage asphalt coating and a preparation method thereof. A waterproof and anti-seepage asphalt coating, which is composed of the following components in parts by weight: 100-250 parts of acrylic emulsion; 50-150 parts of aggregate; 5-15 parts of pigment; 100-200 parts of water; 10 parts; 3-5 parts of anti-seepage agent; 50-100 parts of modified emulsified asphalt; the preparation steps of the modified emulsified asphalt are as follows: vacuumize the emulsified asphalt and the modified liquid under acidic conditions, and heat to 100 -120°C, stirring at a speed of 2500-3000r / min for 20-30min, the modified emulsified asphalt can be prepared; the pH of the acidic condition is 4-6; the modified liquid is composed of modified colloid and modified filler; The modified colloid is composed of hyperbranched polyamide resin, starch and tributyl phosphate. The asphalt coating of the present application has the advantages of waterproof and anti-seepage.

Description

technical field [0001] The application relates to the technical field of asphalt coatings, more specifically, it relates to a waterproof and anti-seepage asphalt coating and a preparation method thereof. Background technique [0002] Asphalt is a brown or dark brown organic gelling material. Due to its excellent characteristics, it is also used in the field of coatings. Taking asphalt coatings as an example, it has the advantages of weather resistance, acid and alkali resistance, and long service life. [0003] The asphalt coating in the related art comprises acrylic acid emulsion, aggregate, pigment, emulsified asphalt and water composition, and this coating is the water-emulsion type waterproof coating that is configured with emulsified asphalt and acrylic acid emulsion as base material, makes aggregate, Pigment, acrylic emulsion and emulsified asphalt are uniformly dispersed in water to form a stable water dispersion, namely asphalt paint. The preparation process is simpl...
