preparation example Construction

[0042] The present invention also provides a preparation method of the building waterproof asphalt caulking ointment described in the above technical solution, comprising the following steps:

[0043] a) subjecting the rubber powder to microwave activation treatment to obtain activated rubber powder;

[0044] b) Mix asphalt, oil slurry, activated rubber powder, diluent and filler, and react to obtain building waterproof asphalt caulking ointment.

[0045] In the invention, firstly, the rubber powder is subjected to microwave activation treatment to obtain activated rubber powder. In the present invention, the rubber powder is the same as that described in the above technical solution, and will not be repeated here. In the present invention, the purpose of the microwave activation treatment is to increase the active sites of the rubber powder, so that the subsequent reaction can proceed smoothly, thereby obtaining a product with better performance. In the present invention, t...

Embodiment 1

[0062] (1) Activate the rubber powder in a JK-MCR-201 microwave chemical reactor at 200 mA for 4 minutes to obtain activated rubber powder;

[0063] (2) Add 100g of asphalt and 50g of oil slurry into a 1L reaction kettle, heat and melt to obtain the base material; then add 70g of waste engine oil, 40g of activated rubber powder and 30g of wood powder, heat up to 170°C and react for 110min to obtain viscous Reaction mixture; then lower the temperature to 150°C, add 50g cyanamide slag, 50g desulfurized gypsum and 50g thiourea slag, and add 10g turpentine, and stir until uniform to obtain building waterproof asphalt caulking ointment.

[0064] JC / T 207-2011 was used to test various properties of the building waterproof asphalt caulking ointment obtained in Example 1, and the results are shown in Table 1.

[0065] The various performance data of the building waterproof asphalt caulking ointment that table 1 embodiment 1 obtains

Abstract

The invention provides construction waterproof asphalt sealing paste and a preparation method thereof. The construction waterproof asphalt sealing paste is prepared from, by weight, 80-100 parts of asphalt, 50-70 parts of slurry oil, 15-60 parts of rubber powder, 60-120 parts of a diluent and 150-400 parts of a packing. Compared with the prior art, the construction waterproof asphalt sealing paste and the preparation method thereof have the advantages that a certain amount of the rubber powder is introduced as a modifying agent, a certain amount of the diluent and the packing are cooperatively used, and good heat resistance is achieved under the premise that various performances of the obtained construction waterproof asphalt sealing paste meet industry standard requirements; the experiment result shows that the various indicators of the provided construction waterproof asphalt sealing paste meet the industry standard requirements, and the heat resistance droops 2mm-3mm at the temperature of 70DEG C.
