Description

Method for repairing musical instrument paint

Technical field

The invention relates to a musical instrument paint repair, in particular to a repair method of a musical instrument paint.

Background technique

At present, the existing musical instrument paint repairs are mainly repaired by returning to the factory for paint repair, or by professionals. This kind of traditional factory-repaired musical instrument paint has a good repair effect, but it takes a long time to return to and from the factory, which is very inconvenient for the user, especially when the user has important performances or training, it can not wait longer. time. In addition to returning to the factory for professional operation by musical instruments, users often do not need to wait for the return time, but they often use their own paint repairs. However, the self-repair is often caused by the user not knowing the color of the guitar paint. Without proper repair methods, there will be obvious traces after repair, which will seriously affect the appearance of the instrument.

Summary of the invention

The invention provides a repairing method for the musical instrument paint which is simple, convenient and practical, and which allows the consumer to easily repair the musical instrument by himself.

A method for repairing a musical instrument paint, comprising the steps of:

The first step is to polish and/or clean the damaged area of the instrument paint;

The second step, preparing the preparation tool and the raw material: the tool comprises a matching bottle with a brush, the raw material comprises a small bottle of paint main agent, a small bottle of thinner and a small bottle of curing agent; the matching tool and raw material are provided by the musical instrument manufacturer Included with the instrument factory or by the instrument manufacturer for each different instrument Don't have different mixing tools and materials.

In the third step, the paint is prepared, and the raw material paint, the diluent and the curing agent prepared in the second step are respectively poured into the mixing bottle with the brush in a ratio of 1:1:1 and uniformly mixed;

The fourth step, make up the paint, use the brush to pick up the paint in the mixing bottle of the third step, apply it to the paint damage of the instrument, dry it, and complete the touch up.

The user of the repairing method of the musical instrument paint of the present invention first cleans the damaged portion of the musical instrument paint, and then firstly mixes the paint with the raw materials provided by the musical instrument manufacturer, and then uses the brush to brush the blended paint on the damaged part of the musical instrument and dry it. Complete the instrument paint repair, the whole process is simple, convenient and practical, so that consumers can easily repair the instrument by themselves. The musical instrument paint repairing method combines the three chemicals of the paint main agent, the diluent and the curing agent in an equal amount to generate a certain chemical reaction, thereby being capable of repairing the paint for the instrument.

Further, in the first step, a specific method of grinding and/or cleaning the damaged portion of the musical instrument paint is as follows:

First use sandpaper to paint damage to the instrument or to grind it, and completely polish the damaged or defective paint;

Then, using a blowing device to perform a cleaning process on the sanding portion;

Finally, the sanding surface is cleaned twice with a dry cotton cloth.

Further, the order of adding the paint main agent, the diluent and the curing agent in the third step is: first pouring the paint main agent into the mixing bottle, and then pouring the same amount of the diluent as the main paint into the mixing bottle, and passing through Stir the thinner and the paint main agent with a stir bar, and finally pour the same amount of curing agent into the blending bottle. Stir well with a stir bar.

Further, the paint main agent is 3 ml to 5 ml, the diluent is 3 ml to 5 ml, and the curing agent is 3 ml to 5 ml. The dosage of the paint main agent, the diluent and the curing agent are all in the form of 3 ml to 5 ml vials, which are not only convenient to use but also convenient to carry and store.

Further, the brushed dispensing bottle is fixed to the outside of the dispensing bottle by a connecting member. The brush is connected with the matching bottle to avoid the disorder of the tool placement, and the tool can not be found when using it, so as to ensure that the brush is taken in time.

Further, the brush is provided with a brush sheath, and the brush sheath is disposed to effectively protect the brush to keep the brush clean and clean.

Further, the curing agent is a room temperature curing agent, and the curing temperature of the room temperature curing agent is room temperature to 50 ° C. A curing agent, also known as a hardener, curing agent or modifier, is a substance or mixture that enhances or controls the curing reaction. The curing reaction is a chemical reaction, which is greatly affected by the curing temperature. The temperature increases, the reaction speed increases, and the gel time becomes shorter. The gel time log value generally decreases linearly with the curing temperature. However, the curing temperature is too high, which often causes curing. The performance of the musical instrument is degraded. Since the repairing method of the musical instrument paint of the present invention is convenient for the user, the user can repair the musical instrument paint by himself, and therefore the room temperature curing agent is used for the curing reaction.

Further, the room temperature curing agent is one or more of an aliphatic polyamine, an alicyclic polyamine, a low molecular polyamide, and a modified aromatic amine.

Further, the diluent is a reactive diluent. The diluent is a liquid substance which is excellent in miscibility with the resin added in order to lower the viscosity of the resin and improve the process performance. Reactive diluent It is a diluent containing a reactive group in the molecule, which participates in the reaction during the process of diluting the adhesive, and at the same time acts as a toughening effect. In the repairing method of the musical instrument paint, the reactive diluent is used to dilute the paint main agent, which participates in the reaction in the process of diluting the paint main agent, and at the same time acts as a toughening effect, effectively improves the adhesion of the paint main agent, thereby ensuring the paint. Patching effect.

The invention can be implemented by the following technical solutions:

The repairing method of the musical instrument paint of the invention has the following beneficial effects:

First, the repairing method of the musical instrument paint of the present invention firstly cleans the damaged portion of the musical instrument paint, and then firstly mixes the paint with the raw materials provided by the musical instrument manufacturer, and then uses the brush to brush the blended paint on the damaged portion of the musical instrument paint and dry. Drying can complete the repair of musical instruments, the whole process is simple, convenient and practical, so that consumers can easily repair the instruments themselves;

Secondly, the musical instrument paint repairing effect is good. The musical instrument paint repairing method combines the three main chemicals of the paint main agent, the diluent and the curing agent in an equal amount to generate a certain chemical reaction, and the diluent can be used as the reactive diluent. Toughening effect, improve the adhesion of the paint main agent, the curing agent uses room temperature curing agent, which is convenient for users to mix paint in the room temperature environment. On the one hand, the user can repair the instrument by himself, and on the other hand, it can effectively ensure the repair of the instrument paint. effect.
