preparation example 1

[0053] The preparation method of modified asphalt A may further comprise the steps:

[0054] Step 1, weigh 1.3 parts of sodium dodecylbenzenesulfonate, 0.8 parts of Foamex-825 defoamer, 1.2 parts of hydroxyethyl cellulose, 0.6 parts of caustic alkali, 1.5 parts of sodium abietate And 42 parts of deionized water, put into the first reactor (commercially available, the electric heating reactor of Laizhou Shenglong Chemical Machinery Co., Ltd.), be warming up to 40 ℃, under the stirring speed of 400 rev / mins, mix 10 Minutes, then heated up to 60 ℃ to save the spare material A;

[0055] Step 2, weighing 50 parts of 70# asphalt, 12.5 parts of 90# asphalt and 5 parts of 110# asphalt, first throw 70# asphalt into the second reactor (commercially available, Laizhou Shenglong Chemical Machinery Co., Ltd. Electric heating reaction kettle), heated to 80°C, and kept stirring for 15 minutes at a stirring speed of 200 rpm, then poured 90# asphalt into the second reaction kettle, controlled...

preparation example 2

[0058] The difference between Preparation Example 2 and Preparation Example 1 is that modified asphalt B is prepared from the following raw materials in parts by weight: 47.6 parts of 70# asphalt, 8.2 parts of 90# asphalt, 2.2 parts of 110# asphalt, 1.2 parts of Sodium dodecylbenzenesulfonate, 0.8 parts of Foamex-825 defoamer, 1.0 parts of hydroxyethyl cellulose, 0.4 parts of caustic, 1.4 parts of sodium abietate and 40 parts of deionized water.

preparation example 3

[0060] Compounding of fillers: Weigh ultrafine calcium carbonate, tetragonal zirconia, pitch-based carbon fiber, and zinc oxide whiskers at a mass ratio of 8.8:1.2:2.3:0.8 , zinc oxide whiskers, put ultra-fine calcium carbonate, tetragonal zirconia, pitch-based carbon fiber, and zinc oxide whiskers into the disperser (twin-shaft stirring disperser, electric heating reactor of Laizhou Shenglong Chemical Machinery Co., Ltd.) , at a stirring speed of 200 rpm, stirred for 2 minutes to obtain filler A.

Abstract

The invention relates to the technical field of asphalt coating production, and in particular, relates to outdoor floor water-based asphalt bottom paint and a processing technology thereof. The outdoor floor water-based asphalt bottom paint is prepared from the following raw materials in parts by weight: modified asphalt, a filler, a film-forming resin emulsion, an emulsifier, a liquid-phase rareearth stabilizer, a film-forming stabilizer, a defoaming agent, an initiator, a UV agent and deionized water. The water-based asphalt bottom paint provided by the invention has good corrosion resistance, low temperature resistance and aging resistance, and can improve the impact strength of outdoor floors. The processing technology comprises the steps: weighing the modified asphalt, adding the modified asphalt into a proportioning device, weighing the film-forming resin emulsion and deionized water, sequentially adding the weighed filler, the weighed liquid-phase rare earth stabilizer, the weighed UV agent, the weighed emulsifier, the weighed film-forming stabilizer, the weighed defoaming agent and the weighed initiator into the proportioning device, stirring, vacuumizing, naturally cooling to room temperature, and finally screening and filling. The process has the advantage that the high-quality asphalt bottom paint can be obtained through quantitative production.

Description

technical field [0001] The application relates to the technical field of asphalt paint production, in particular to a water-based asphalt primer for outdoor floors and a processing technology thereof. Background technique [0002] The outdoor floor must be able to withstand the changeable outdoor weather and strong temperature changes. Therefore, the floor must have the characteristics of strong stability, strong corrosion resistance, and strong pressure resistance. By coating the surface of the outdoor floor with anti-corrosion primer or anti-corrosion paint. At present, the vast majority of anti-corrosion coatings at home and abroad are mainly solvent-based coatings. Solvent-based anti-corrosion coatings pose a greater threat to the environment and human health. The study of lacquer has received great attention. Asphalt is a commonly used anti-corrosion material with low cost and wide sources of raw materials. Petroleum asphalt has good adhesion, anti-aging and anti-cor...
