Problems solved by technology

There are also a few made of plastic and wood, but the disadvantages of those made of plastic and wood are that the structure is loose and fragile. During the plucking process, the strings and the string nuts are rubbed, which can easily cause the string nuts to break, loosen, and sink. It causes and the sound is fluttering, unreal, and weak, which affects the effect of pronunciation, and then affects the normal use of the guitar

Abstract

The invention discloses a guitar nut and a preparation method thereof. The guitar nut includes the following raw materials in parts by weight: 120-140 parts of high-density polyethylene, 20-40 parts of carbon fiber, 30-50 parts of high-strength nylon, 1-3 parts of a lubricant, 1-3 parts of a coupling agent, 1-2 parts of an antioxidant, 2-6 parts of metal rare earth and 2-4 parts of diphenyl octylphosphate. Through adoption of the carbon fiber, it is ensured that the guitar nut has the advantages of high strength and friction resistance, and the requirements of a guitar for the nut are ensured; and the guitar manufactured by using the nut has pure sound quality, long guitar-string resonance time and good graininess.

Description

technical field [0001] The invention relates to a guitar string nut material, in particular to a guitar string nut and a preparation method thereof. Background technique [0002] The sound of a plucked instrument is not only closely related to the material of the body, quality of the strings, production technology, playing skills and other factors, but also has a very close relationship with the material of the string nut. As a musical instrument accessory, the string nut is mostly used for guitars, On plucked instruments such as basses and camel bells, it plays the role of supporting the strings, fixing the strings at specific positions, and thus emitting various tones; the string nuts are divided into upper and lower types, and in some places, the string nuts are called Shangju pillows. , Upper nut, upper bridge, etc., and the lower nut is called Xiaju pillow, lower nut, lower bridge, etc.; the string nut has many specifications, and there are lengths, heights, and thickne...
