Problems solved by technology

[0002] The more popular waterproof material in the existing market is that solid asphalt is heated into a liquid and brushed on the building, and then glued with composite tinfoil. Its disadvantages are: high cost, waste of limited resources, and heavy smoke that pollutes the environment when heated
After sticking, it can no longer be dried or stepped on. If the tinfoil is scratched, the asphalt will age faster in a short time, cracks will appear again, and water will continue to leak. And it can only be constructed on sunny days when the air temperature is high and liquid asphalt is added. High temperature, easy to cause heatstroke or burns, not suitable for use in water or underwater

Embodiment 1

[0019] It is better to use ordinary scrap steel, which is easy to process, and finished steel is also acceptable, but the cost is too high, and it is processed into fine powder by electric grinding wheel, cutting machine or large-scale special pulverizer, and high temperature is generated during the processing, and the Moisture in the steel is detached, absorbed by a magnet (or electromagnet), and then removed and stored in a sealed bag to prevent moisture. You can also add a desiccant, which requires high-purity fine steel powder. The higher the purity, the better the plugging effect; Sodium chloride is dissolved in water to make a sodium chloride aqueous solution with a concentration of more than 20%. It is preferably packed in a plastic bottle for use. A small hole is drilled on the cover, and it will flow out when pinched by hand.

[0020] The construction steps are as follows: Find the cracks on the building surface, take steel powder and sprinkle it evenly in the cracks, ...

Embodiment 2

[0022] If there is water seepage in reservoirs, rivers, dams or small cracks, use more than 90% high-purity steel powder to soak in more than 90% sodium chloride aqueous solution, and put it into seepage places or cracks after 20-40 minutes.

Abstract

The present invention relates to building material, and is especially one kind of waterproof and rainproof material and its preparation process. The waterproof and rainproof material consists of fine steel powder and water solution of sodium chloride in 20 wt% over concentration. Its preparation process includes crushing steel in an electric grinder or special grinding machine and packing the steel powder in sealing bag; and dissolving sodium chloride in water to form water solution of sodium chloride in 20 wt% over concentration. When it is used, the steel powder is first sprayed into crack in building and the water solution of sodium chloride is then poured into the crack. The present invention has low cost and no environmental pollution.

Description

(1) Technical field [0001] The invention relates to a building material, in particular to a waterproof and rainproof material and a manufacturing method thereof. (2) Background technology [0002] The more popular waterproof material in the existing market is that solid asphalt is heated into a liquid and brushed on the building, and then glued with composite tinfoil. Its disadvantages are: high cost, waste of limited resources, and heavy smoke pollution when heated. After sticking, it can no longer be dried or stepped on. If the tinfoil is scratched, the asphalt will age faster in a short time, cracks will appear again, and water will continue to leak. And it can only be constructed on sunny days when the air temperature is high and liquid asphalt is used. The high temperature can easily cause heatstroke or burns, and it is not suitable for use in or underwater. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the inventio...
