Abstract

The invention aims to provide a high-solid-content epoxy composite material for a badminton racket. The high-solid-content epoxy composite material for the badminton racket is prepared from the following components in parts by weight: 70 to 90 parts of epoxy resin, 20 to 30 parts of butyl methacrylate, 5 to 10 parts of nano-titanium sol, 2 to 3 parts of curing agent, 2.5 to 5.5 parts of amino polyether, 3.5 to 4.5 parts of carboxylic styrene butadiene rubber, 1 to 3 parts of antirust agent, 2 to 4 parts of dispersing agent, and 2.5 to 5 parts of flatting agent. The invention also discloses a preparation method of the composite material. The composite material is higher in solid content and has favorable flexibility at the same time. The composite material also has the characteristics of excellent recoatability, high coverability, and acid and alkali corrosion resistance.

Description

[0001] This application is a divisional application of the invention patent with application number 201610165046.8. Technical field: [0002] The invention designs a high-solid-content epoxy composite material, especially a high-solid-content epoxy composite material suitable for badminton rackets. Background technique: [0003] The coating material with high solid content has good hiding power and large coating area, which can greatly reduce the content of volatile organic compounds in the coating material and the energy consumption of the curing process during the construction process. Therefore, the use of coating materials with high solid content has become the first choice of various businesses, but coating materials with high solid content still have some defects in performance. [0004] Sports rackets will be impacted by balls during use and produce small vibrations, which have higher requirements on the flexibility of coating materials. However, when the solid conte...
