Description

Waterproof coating construction method

The invention relates to a construction method of a waterproof coating film; in particular, an innovative inventor who can make the waterproof coating agent penetrate into all the pores in the surface of the construction object without any holes, and comprehensively form a construction method of filling the waterproof coating with closed adhesion.

According to the coating structure, it is widely used in various high-priced electronic products and their components. For example, recently popular mobile phones are popular for waterproof coating or scratch-resistant protective coating treatment to prevent internal components from malfunctioning due to moisture or surface. Scratch the wearer.

The above-mentioned waterproof coating treatment generally attaches a liquid waterproof coating agent to the surface of the construction object by means of coating or spraying, so that the coating agent forms a coating layer on the surface of the construction object (or spray adhesion layer). Structure) to achieve the protection against surface scratches.

However, the above-mentioned coating layer structure (or spray adhesion layer structure) formed by the water-repellent coating agent on the construction object may have dead corners or pores which cannot be completely adhered during construction, and cannot form a comprehensive attachment structure effectively. The inability to achieve comprehensive protection is one of its shortcomings.

Moreover, taking the mobile phone as an example, if the internal parts are to be protected from moisture, the construction must be dismantled before the construction can be carried out, resulting in inconvenience in construction and delay in the construction period, which is the second disadvantage.

Finally, since the warranty requirements of general mobile phones (including other electronic products) will be determined that the casing cannot be removed, once the casing is disassembled for construction, the loss of the construction object will be lost, which is the third disadvantage.

Therefore, how to innovate the inventors for the inability of the above-mentioned waterproof coating system to be fully attached and protected, and the inconvenience of having to disassemble the product casing and the loss of the warranty may be the difficult points to be solved in this case. Where.

The main object of the present invention is to provide a waterproof coating The construction method can make the waterproof coating agent penetrate into all the pores of the construction object, and fully form the waterproof coating structure filled with the closed attachment, and achieve the progressive use of the comprehensive protection inside and outside the table.

A second object of the present invention is to provide a waterproof coating film construction method, which can perform waterproof coating construction without disassembling the product casing, and effectively improve the convenience of construction operation and the progress of construction speed.

Another object of the present invention is to provide a method for constructing a water-repellent coating which can be removed without the need to disassemble the casing to avoid loss of warranty.

To achieve the above object, the present invention comprises the following procedures:

(a) A negative pressure environment preparation procedure, in which a negative pressure tank has a sealing cover with a see-through material in one opening, which can be composed of an open cover to form a closed environment, and a negative pressure suction port which can be connected to a negative pressure pump is arranged on the outer wall. And prepare a construction container larger than the construction object to hold the liquid waterproof coating agent.

(b) Negative pressure coating construction procedure, immersing the construction object in the construction container waterproof coating agent, placing the construction container into the negative pressure box, closing the negative pressure box sealing cover, and passing through the negative pressure suction port and a negative pressure pump The pump is connected to the negative pressure suction to form a negative pressure environment, and all the pore hidden gas inside the construction object overflows the waterproof coating agent by the internal and external pressure difference of the waterproof coating liquid level under the negative pressure environment. In addition to the liquid level, the water-repellent coating agent can be infiltrated into all the pores of the construction object without any perforation, and the water-repellent coating structure filled with the closed attachment is fully formed.

(c) Finished product procedure, the liquid surface of the waterproof coating agent of the construction container inside the negative pressure box is seen from the sealing cover. When the liquid surface no longer emits air bubbles, it means that all the pores in the construction object table have been completely filled with the waterproof coating agent. When it is full and forms a closed-type waterproof coating structure, the vacuum suction can be stopped and the sealing cover can be opened, and the construction object can be taken out as a finished product.

According to the above, the waterproof coating agent is a kind of nano waterproof sealing agent.

Please refer to FIG. 1 and FIG. 2, and the present invention includes the following procedures:

(a) Negative pressure environment preparation procedure, as shown in the second figure, a negative pressure tank 10 is provided with a transparent material in an opening The cover 11 can be composed of an open cover to form a closed environment, and a negative pressure suction port 12 for connecting a negative pressure pump (not shown) is disposed on the outer wall; and a construction container 20 larger than the construction object is prepared for the outer cover. The liquid waterproof coating agent 30 (which is a nano waterproof sealing agent) provides a construction article 40 (in the embodiment, a mobile phone as an example).

(b) Negative pressure coating construction procedure, in conjunction with the third figure, a construction object 40 (mobile phone) is immersed in the waterproof coating agent 30 of the construction container 20, and the construction container 20 is placed in the negative pressure tank 10, and the negative pressure tank is placed. The sealing cover 11 is closed, and the negative pressure suction port 12 is connected to a negative pressure pump (not shown) for negative pressure suction to form a negative pressure environment, and the liquid level of the waterproof coating agent 30 is under negative pressure. The internal and external pressure difference in the environment causes all the pore hidden gas inside the construction object (mobile phone) 40 to overflow the liquid surface of the waterproof coating agent 30, so that the waterproof coating agent 30 can penetrate into all the pores of the construction object (mobile phone) 40 without any holes. The water-resistant coating structure filled with closed adhesion is fully formed.

(c) Finishing procedure, in the third figure, the liquid surface of the waterproof coating agent 30 of the construction container 20 inside the negative pressure tank 10 can be seen through the sealing cover 11, and when the liquid surface no longer emits bubbles, the construction object (mobile phone) 40 All the pores in the watch have been completely filled with the waterproof coating agent to form a closed-type waterproof coating structure, which can stop the vacuum suction and open the sealing cover 11. The construction object (mobile phone) 40 is taken out as a finished product.

The fourth figure is a schematic diagram of the waterproof test of the construction object according to the present invention. As shown in the above figure, the construction object (mobile phone) 40 for completing the waterproof coating construction can be immersed in a basin of water 50, which can be formed by the above-mentioned construction adhesion. The waterproof coating structure is completely waterproof; as shown in the figure below, when the construction object (mobile phone) 40 number is dialed, the construction object (mobile phone) 40 immersed in the water can still receive the call signal and open the call screen 41.
