Problems solved by technology

The disclosed special treatment agent is mainly composed of water-soluble paraffin. However, the adhesion of water-soluble paraffin is not enough, and it is easy to fall off after long-term use, which leads to the weakening of the anti-efflorescence ability of the stone.

Embodiment 1

[0020] Embodiment 1: The preparation method of the asphalt anti-alkali and waterproof agent in the present embodiment, take asphalt, the operation steps are:

[0021] 1) The step of asphalt cooking, first break the asphalt into pieces, put it into the asphalt pot and heat it evenly, stir it at any time during the heating process, and use a colander to remove the sundries in time after melting, until it is dehydrated and free of foam;

[0022] 2) The configuration steps of the asphalt alkali-proof and waterproof agent. The asphalt prepared in the above steps is mixed with diesel oil to obtain the asphalt alkali-proof and waterproof agent. The ratio is: asphalt:diesel oil=40:60. Put the asphalt into the container, cool it to 110°C, slowly inject diesel oil, and stir it as you inject it, until it is completely dissolved. 3 / 4 of the volume of the oil pan, the temperature of the asphalt should not exceed 80°C, and there must be no flammables, no smoking and open flames nearby durin...

Embodiment 2

[0023] Embodiment 2: A construction method for preventing efflorescence of stone materials, using the asphalt alkali-proof and water-repellent agent prepared in the above-mentioned embodiment, the steps are as follows:

[0024] 1) The relevant stone should be inspected first before use. Not only the appearance and size must be qualified, but also its physical performance indicators must be qualified. First, clean the dust and debris on the surface of the stone, and then use the stone efflorescence cleaning agent on the market to clean the stone. Plates are painted. The cleaning agent is a colorless translucent liquid made of non-ionic surfactants and solvents, which has a certain effect on cleaning efflorescence on the surface of natural stone;

[0025] 2) The steps of applying the asphalt anti-alkali and waterproof agent, before painting, check again that the surface of the stone base is dry and smooth, and then use the asphalt anti-alkali and waterproof agent to paint a larg...

Abstract

The invention relates to a preparation method for an asphalt alkali-preventing water-resisting agent and a construction method for applying the same in prevention of efflorescence of stone. Measures are taken to prevent efflorescence. The preparation method for the asphalt alkali-preventing water-resisting agent is characterized by comprising the following operation steps: 1) weighing and boiling of asphalt; and 2) preparation of the asphalt alkali-preventing water-resisting agent. With the construction method provided by the invention, efflorescence of a natural stone wall surface laid in wet conditions can be effectively prevented, occurrence of efflorescence can be completely avoided as long as links like designing, material selection and construction are strictly checked and scientific control is controlled out, and the ancient building material--natural stone is allowed to play an amazing role in modern buildings.

Description

Technical field [0001] The present invention involves a method of preparation of asphalt waterproofing agent and the use of the preparation to prevent the construction method of stone pan -alkali. It takes measures to prevent the cause of pan -alkali phenomenon. Background technique [0002] During the installation of the natural stone wall surface, the stone section will appear like"watermark"like plaques. With the hardening and drying of mortar inlaid mortar,"watermark"will shrink slightly, even some disappear disappearedIts isolation and decentralization appear in the plate, the indoor degree is not serious, and the appearance is not large.However, over time, especially the exterior walls have repeatedly encountered rain or humid weather, the water invaded from the seams and wall roots, and the water spots of natural stones gradually became larger, and it was connected to the seams.The white crystal is emitted with the seams, which has not faded for many years, which seriously...
