Anti-leak agent for metal container

Abstract

The invention relates to a modified anti-leak agent for metal container which comprises (by weigh percent) alkide resin paint 20-80%, Griffth's white powder 20-80%, and filling material 0-60%.

Description

technical field [0001] The invention relates to an improved leak-trapping agent for metal containers and belongs to the technical field of chemical products. Background technique [0002] Containers used in daily life, especially metal containers, such as iron pans, aluminum pans, frying spoons, kettles, iron basins, aluminum basins, enamel basins, water tanks, oil tanks, radiators, heating pipes, water pipes, glass fish tanks, etc., use During the process, defects such as small cracks, trachoma, and loopholes are often encountered, while other parts are intact. This small defect directly affects the use of the product, resulting in a greatly shortened service life. The re-use of sticky patching has been recognized by people, and there have been various corresponding sticky patching agents or patching supplies, which are: (1) Self-adhesive aluminum foil tape: easy to use, the biggest disadvantage is Afraid of water, fire, and friction, it is not durable, and it will fall of...

AI Technical Summary

Problems solved by technology

[0002] Containers used in daily life, especially metal containers, such as iron pans, aluminum pans, frying spoons, kettles, iron basins, aluminum basins, enamel basins, water tanks, oil tanks, radiators, heating pipes, water pipes, glass fish tanks, etc., use During the process, we often encounter defects such as small cracks, trachoma, and loopholes, while other parts are intact. This small defect directly affects the use of the product, resulting in a greatly shortened service life.

The re-use of sticky patching has been recognized by people, and then various corresponding patching agents or patching supplies have appeared, which are: (1) Self-adhesive aluminum foil tape: easy to use, the biggest disadvantage is Afraid of water, fire, and friction, it is not durable, and it will fall off automatically if it is washed with hot water several times; if it is patched on a rice cooker, it will melt naturally once it is heated by contact with the stove; if the hole on the container exceeds 0.5 cm cannot be used, because the aluminum strip is too thin, only 0.01mm thick, and it will be damaged if it is slightly touched

(2) Soldering: There are special repairing industries or processing industries that use soldering tin for repairing. The cost of soldering is high, and not everyone can do it. If it is patched on the pot, the solder will melt and fall off automatically when the temperature is high

(3) Rivet repair method: If the container to be repaired is too thin, the rivet operation cannot be performed; the convex surface of the thicker container is too high after rivet repair, which is inconvenient to use and is also very easy to be riveted.

(4) Welding: When there are cracks and leaks in radiators, heating pipes, tap water pipes, etc., there is no more effective method except electric welding. However, for cast iron radiators and heating pipes, there is no good way. After several times of thermal expansion and contraction, cracks, cracks, etc. will reappear, and the effect is poor

In fact, in some special occasions and environmental conditions, it is impossible to implement sticky repair technology at all, such as water tanks and fuel tanks used in motor vehicles. It is not an easy task to repair with electric welding. First, the water tank Most of them are made of cast iron and cannot be welded. Second, the fuel tank is prone to explosion and accidents during welding, which is very dangerous

So far, there is no one adhesive product that can meet multiple requirements and adapt to multiple situations
