A kind of preparation method of guitar material

Abstract

The invention discloses a preparation method of a guitar material, comprising the following steps: A: making wood fibers into thin slices in a conventional manner; B: impregnating the thin slices in phenolic resin mixed with a flame retardant; C. The impregnated slices are dried at 140-160°C for 4-6 minutes; D. After stacking the dried slices, put them on a press for high-temperature and high-pressure extrusion at a temperature of 140-160°C ℃, the extrusion pressure is 1430psi, and the extrusion time is 10-15h; E. The extruded sheet can be cooled naturally; the weight ratio of wood fiber in the final guitar material is 60%, and the phenolic resin is 30%. %, flame retardant is 10%. The guitar made of the material has excellent acoustic effect, shortens the production period of the guitar, and has excellent physical performance of the material.

Description

technical field [0001] The invention relates to a material preparation method, in particular to a guitar material preparation method. Background technique [0002] The overall structure of the guitar mainly includes panels, back panels, side panels, fingerboards, piano heads, bridges, strings, etc. Most of these components are made of wood. Acoustic guitar is highly praised and loved by people because of its excellent acoustic effect. However, there are also some problems in the acoustic guitar itself: 1. Most of the components of the acoustic guitar are made of wood. Due to the slow growth cycle of trees, the growth of trees cannot meet the needs of the market, thus restricting the development of enterprises and excessive felling of trees It will also cause environmental damage. 2. The production process of guitars made of wood is relatively complicated. The production cycle of ordinary guitars is about 1 month. Among them, the guitar painting process needs to be repeated...

Problems solved by technology

However, there are also some problems in the acoustic guitar itself: 1. Most of the components of the acoustic guitar are made of wood. Due to the slow growth cycle of trees, the growth of trees cannot meet the needs of the market, thus restricting the development of enterprises and excessive felling of trees also cause damage to the environment

2. The production process of guitars made of wood is relatively complicated. The production cycle of ordinary guitars is about 1 month. Among them, the guitar painting process needs to be repeated more than 10 times and it takes more than 20 days. The production cycle of high-end products It takes more than 3 months, and the painting process is more complicated

The harmful substances in the painting process are likely to cause harm to the human body.

Moreover, guitars made of wood also need to be edged, polished, polished, etc., and the production cycle is relatively long.

3. The wood itself is easy to expand with heat and contract with cold, so the acoustic guitar cannot be used in extreme environments, and it is easy to crack in a dry environment, and it is prone to bulges in a humid environment

Moreover, in a humid environment, the acoustic effect of the wooden guitar will change after the wood absorbs water, and the sound will be dull.

4. The surface of the acoustic guitar is easy to leave marks after being scratched, it is not easy to clean the surface after it is polluted, and it is easy to leave scars after burning the cigarette butt

Due to the many disadvantages of wooden guitars, people have been looking for a new material to replace wood. For example, some people try to use carbon fiber to make guitars, but the acoustic effect of guitars made of carbon fibers is much different from that of wooden guitars. big, people can't take it
