Abstract
The invention discloses a string with high tensile strength. The string comprises a string body and a strengthened layer, wherein the strengthened layer is arranged on the surface of the string body, and comprises the following components in percentage by weight: 40%-60% of a plastic raw material, 15%-25% of polyvinyl chloride and 25%-35% of glass fiber. The string has the advantages of high strength, high corrosion resistance, good weather fastness, high shock resistance and the like.
Description
Technical field
The present invention relates to string field, specifically, be related specifically to the string that a kind of tensile strength is large.
Background technology
Chinese musical instruments manufacturing has basically formed comparatively complete industrial production system, substantially all large kind musical instruments in the world can be processed, covering extensive fields, kind is numerous, different classes of more than 1200 models such as nearly piano, violin, western wind instrument, specification more than 30,000, the large kind musical instrument such as piano.Its product has formed Virtual production general layout, and the main piano parts specialty such as piano iron plate, soundboard, hammered string instrument, shell source mill starts to form scale.
Summary of the invention
The object of the invention is to for deficiency of the prior art, provide the string that a kind of tensile strength is large, to solve the problem.
Technical problem solved by the invention can realize by the following technical solutions:
The string that tensile strength is large, comprise string body and the strengthening layer being arranged at string body surface, it is characterized in that, the component of described strengthening layer comprises plastic raw materials, polyvinyl chloride and glass fibre, described plastic raw materials content is 40-60%, described polyvinyl chloride content is 15-25%, and the content of described glass fibre is 25-35%, and described content is weight percentage.
Preferably, described polyvinyl chloride optimum content is 20%.
Preferably, the optimum content of described glass fibre is 30%.
Compared with prior art, beneficial effect of the present invention is as follows:
The present invention has the advantages such as intensity is high, erosion resistance strong, good weatherability, strong shock resistance.
