Description

The present invention has an old paint film that has already been painted or is newly established, mainly in the construction / architecture field, but for objects to be coated that require cleaning, polishing, footing, and sanding operations. This is a cleaning and polishing brush used in the steps of cleaning, polishing, footing and sanding before painting.

When painting an object, the surface treatment process before painting is usually very important. If this process is insufficient, it may cause various problems such as coating film peeling after coating. Therefore, the amount of work and time are spent, and unreasonable work (cleaning work, polishing, footing, sanding work are performed in separate processes, and cleaning work is also performed each time) is currently required. is there.

However, in an economic downturn and a price-competitive society, it is also important how to reduce costs, and from the viewpoint of effective use of work time, efforts to shorten the construction period and reduce costs are constantly promising.

The following are the pre-painting processes for the objects to be coated in the general construction and construction fields.

1. Check and check the material of the object and the type of the old paint film, the degree of adhesion of the old paint film, float / peel, rusting, dirt, etc., the surface condition, and the type of paint to be applied from above.
2 Use a high-pressure washing machine or the like that can spray water at high pressure on the object to be coated, or perform washing work manually, and at the same time, remove dust etc Cleaning work will be done later for aesthetic and safety reasons.
3 Check the surface of the material to be coated and the state of the old paint film after cleaning, and if necessary (mostly necessary), use the power tool or sandpaper, etc. Polishing, footing and sanding work to improve performance.
4. After cleaning the old paint film, rust, and other debris that has been removed during polishing, footing, and sanding, check the surface to be painted, and then perform the base preparation process with putty, etc., or the curing process before painting. Do.
5 painting process

As a conventional technique, in most cases, it is usual to perform coating while taking the above steps into account.

Usually, the washing and washing process of 2 is carried out in the case where there is an old coating film, removal of the floating old coating film, removal of the old coating film that is not sufficiently adhered to the object to be coated, and degradation of the coating film surface over time. The pressure of high pressure washing is about 150-200Kgf / cm2, and the old paint film that is in close contact with the halfway cannot be completely removed. It cannot be removed.

Then, the pressure for high-pressure cleaning should be increased more, but if it is increased above the above value, the material itself may be damaged. It has become. Then, the present situation is that polishing, footing, and sanding operations are performed in order to compensate for the insufficiency of the second washing and washing process.

Produced with a large number of hairs (hairs made by mixing abrasive particles used in sandpaper etc. into a nylon base that is strong and flexible so that it can be ground, grounded, and sanded). Products have been previously marketed.

For example, the shape is similar to a toothbrush, and the size is a little larger than that, which is called a grit brush or a channel grit brush, or a cup type (a round shape with various sizes from 50 mm to 125 mm in diameter) There are tools that can be mounted on a power tool and can be ground, grounded, and sanded by rotation.

All of them are used as a base treatment before painting mainly in car-related plating coating factories.
However, it is only for small area polishing, footing and sanding work and is not suitable for large area work.

Also, wire-like metallic bristles are planted in the brush body, such as car wash brushes with handles attached to the brush body, deck brushes, and other various commercially available products However, because the metallic hair is implanted, the old paint film or material is deeply scratched, and when the paint is applied on top, the film thickness is extremely thin. Cannot be concealed, and scratches on the surface become conspicuous after the coating film is dried. Therefore, these are more suitable for peeling and chipping operations than for polishing, footing and sanding operations.

Various types of brushes designed for normal car washing and washing, with a hair pattern such as horse hair mixed hair, nylon, palm, packing, etc., attached to the brush body, have been commercially available. Some of them are used for car washing and washing because they are not suitable for polishing, footing and sanding.

Furthermore, various products (nonwoven fabric abrasives) in which abrasive grains are bonded to a cloth (= nonwoven fabric) in which fibers are bonded to sandpaper / abrasive wheels are commercially available, all of which are used manually. However, it is difficult to use in combination with high-pressure washing with water from the viewpoint of safety, and these are suitable for polishing, footing and sanding operations on flat surfaces, and are not suitable for complex uneven surfaces.
From the above, there is no such thing that achieves the above purpose.

The washing and washing process of 2 depends on the area to be washed, but taking a typical house building (painting area of about 150m2) as an example, it takes about 2 to 3 hours at the earliest. Will be finished in about 4-5 hours. That is, in most cases, when the cleaning process is started from the morning of the day, the work is completed in the morning.

And if we can do 3 polishing, footing and sanding immediately, the process will be carried over to the next day because the work is wet with water, and the process 3 and cleaning cannot be performed until the water evaporates and dries. It will be. That is, this work is often completed in a half-day work.

In many cases, the labor cost of the craftsman who performed the cleaning work is paid as the labor cost of the work for one day even if it is a half-day work. In addition, in the case of a company that takes a salary system, it is only necessary to work from the afternoon, but if it is not done, it will pay for one day with half a day of work.

If the work takes a long time at the same time as the 3 polishing, footing and sanding operations after the work is dried, the work site must be organized, organized and cleaned as soon as possible. This cleaning operation is also inevitable after the third polishing, footing and sanding operations. That is, the cleaning operation is repeated at least twice during the process.

In the washing and washing process 2, one person is a washing operator, the other is a work instruction, and the person who plays a supplementary role for the washing operator is in most cases compared to the washing worker. Therefore, it can also be used for other operations (polishing, footing, sanding, etc. at the same time).
However, if you attempt to perform polishing, footing, and sanding at the same time as washing with water, the work with the power tool is likely to cause damage or damage to the power tool because the tool itself gets wet with water. There is no use. In the manual work, abrasive materials such as sandpaper and abrasive cloth are usually used. However, the water pressure of the high-pressure cleaning is very high, which may damage the hand and damage the abrasive material. Is not possible.

Therefore, useless time and waste are spent in the process of cleaning work → cleaning work → polishing, footing, sanding work → cleaning work.

The present invention has been developed in view of the above points, and the object of the present invention is to perform polishing, footing and sanding operations in the next process mainly in the washing and washing process. Develop a brush that can be used.
・ By using this brush, the cleaning work usually twice or more is shortened as much as possible.
For the above two purposes, the amount of work and the working time are reduced, and at the same time, the above-mentioned Step 2 and Step 3 are combined into one to reduce the total cost of the overall painting work.

In order to effectively achieve the above object, the present invention has the following configuration. As described above, there are a car wash brush type and a deck brush type as described above. The detailed shape is almost the same as that usually marketed.

A large number of bristles planted on at least one side are made of a synthetic resin centered on nylon and encapsulated with abrasive grains as abrasives, and made into a thread so that the abrasive grains do not fall off. It is planted in. The bristles are regularly arranged on one side of the brush body, so that dirt, dirt, dust, and coating fragments from polishing, footing, and sanding work are not entangled between the hairs. The gap of hair is secured.

As the abrasive particles as the abrasive, various sizes having a diameter of 0.3 to 1.3 mm are used, and the particle size can be adjusted according to the required accuracy of polishing, footing and sanding work. For example, an abrasive paper called sandpaper, which is usually commercially available, is used. A coarse sandpaper has a coarse particle size and a large abrasive particle diameter. In contrast, fine sandpaper has a fine particle size and a small abrasive particle diameter. By changing the size of these abrasive grains and encapsulating the abrasive with the grain size adjusted in a synthetic resin centered on nylon, a brush capable of adjusting coarse and fine polishing accuracy can be produced.

The bristles of this cleaning and polishing brush are made by mixing abrasive grains used in sandpaper etc. with a strong and flexible nylon base so that polishing, footing and sanding can be done. However, three types of coarse, medium, and fine counts are prepared from the above depending on the accuracy of polishing, footing, and sanding operations on the object to be coated. With this accuracy, considering the balance between the surface condition of the material (rusting, dirt, etc.), the surface condition of the old paint film (choking, peeling, floating, dirt, etc.) and the coating specifications to be applied after the surface treatment, Select a count from three types: coarse, medium and fine.

Because the hair of this cleaning and polishing brush changes the ground contact area of the hair planted on the brush depending on the shape of the object to be coated, since the synthetic resin centered on nylon is the main component, the tip of the hair is easily scissors etc. For example, in the case of a corrugated tin, it is possible to match the unevenness of the corrugated tin by checking the ground contact portion and cutting the hair tip.

The handle attached to the brush body ensures the length of the handle attached to the brush body directly so as not to touch the water pressure of the high-pressure washing machine to ensure the safety of workers. Keep your hands and body away from water and be thick enough to be grasped by your hand.

For the car wash brush type of this washing and polishing brush, the inner thread of the tip part (part d in FIG. 4) on the opposite side of the brush body of the handle attached to the brush body is cut, and a little handle length is required. Can be attached to the extension pole.

According to the present invention, as described above, since the cleaning operation in Step 2 and the polishing, footing, and sanding operations in Step 3 are performed at the same time, the amount of work and the work time are reduced, and the worker is effective from the standpoint of the employer. Secure employment status. And in the overall painting work, the construction period is shortened and the total cost is reduced.

This brush is made of synthetic resin centered on nylon, and abrasive particles are encapsulated in it, so that the abrasive is not dropped during cleaning, polishing, footing and sanding operations. It has moderate rigidity and elasticity. In addition, since it is made of nylon, it has low moisture absorption, is excellent in water resistance, abrasion resistance, and chemical resistance, and is particularly excellent in alkali resistance.

As abrasives, Morundum-alumina abrasives, dinchic-silicon carbide abrasives, etc. are used, and as described above, the accuracy of polishing, footing and sanding operations is improved by changing the abrasive grain size. It is a cleaning and polishing brush having an abrasive property that can be adjusted.

As the abrasive particles as the abrasive, various sizes having a diameter of 0.3 to 1.3 mm are used, and the particle size can be adjusted according to the required accuracy of polishing, footing and sanding work. As with abrasive paper called sandpaper, which is usually available on the market, it is possible to select coarse to fine according to various applications, and adjust the surface of the object to be coated according to the required accuracy. Can do.

The main applications are 6 when the surface is mainly a mirror surface or a fine flat surface, and it is necessary to perform cleaning, polishing, footing and sanding before painting. (New installation and repainting)
7 When the object is painted, the old paint film is peeled, floated, choked, etc., dirty, and requires polishing, footing and sanding.
8. When you want to remove stubborn dirt without damaging the material as much as possible because it also has the effect of scraping off deposits.
For example, in the case described above, the present invention can be applied to all cases where cleaning, polishing, footing, and sanding work are mainly required.

Regarding No. 6, it is in the ground treatment process at the time of painting of newly installed and repainted old paint film, and when the paint is applied to the object, the more rough the surface, the more the object to be coated For a flat surface with a good mirror surface and fine texture, the surface of the object to be coated is usually subjected to a process called wrapping using sandpaper or the like before coating. It can be used for the purpose of sighting, and at that time, the precision of polishing, footing and sanding work is adjusted according to the type of paint to be applied thereafter.

In addition, even if the paint is not applied, if the surface of the object to be coated is soft and weak, the object to be coated will be damaged, causing damage or damage to the object to be coated and detracting from the value of the object. However, if the surface of the object to be coated is hard and the cleaning / polishing brush is not scratched or can be damaged, it is better to use a cleaning brush that is usually available on the market. Since it has grinding ability and rigidity, it has an excellent effect of removing dirt and the like, so that the working efficiency can be increased.

For 7, there is mainly an old paint film, and the surface treatment process at the time of repainting the surface is different from the case of 6, and the old paint film is deteriorated and deteriorated with time. The coating film is affected by ultraviolet rays and the like, and the deterioration and degeneration of the surface proceeds, causing a choking phenomenon, and a phenomenon such as floating and peeling. Under these conditions, the paint cannot be applied immediately without any treatment, so the surface should be free of dirt and choking, the old paint film that floats, For the purpose of removal, etc., a washing operation by high pressure water washing is performed.

However, as mentioned above, because it is an inadequate work, in order to make up for it, this cleaning and polishing brush is used together in the same process, and the cleaning, polishing, footing and sanding operations are performed at the same time, thereby improving the work efficiency. be able to.

As for No. 8, scrape off deposits stuck to the object to be coated (eg metal rust, algae / mold attached to stones) and stubborn dirt (alkaline components of concrete, etc.) with chemicals etc. It can be used for such purposes.

In addition to the above purposes, it can be used for a wide variety of purposes as much as possible in cleaning, polishing, footing, and sanding work, and has many people use it for various purposes from contractors to general consumers. Can do.

Specifically, it can be applied to the steps of cleaning, polishing, attaching, and sanding of roofs, walls, panels, and other incidental parts of general buildings, automobiles, trains, airplanes, and the like.
