Abstract

The invention discloses a handle rubber material for a baseball bat. The handle rubber material for the baseball bat comprises the following raw materials: a surface layer material and a foaming bottom layer material, wherein the surface layer material comprises the following raw materials: water-based polycarbonate type polyurethane resin, a polyurethane thickening agent, a defoaming agent, a wetting agent and a hand feeling agent; and the foaming bottom layer material comprises the following raw materials: water-based polycarbonate type polyurethane resin, a polyacrylic ester thickening agent, fillers, a foaming agent and a crosslinking agent. The handle rubber material has the characteristics of excellent wear resistance, air permeability and moisture permeability as well as good hand feeling, has a good air-permeable and moisture-permeable effect, and is applicable to the baseball bat.

Description

Technical field [0001] The invention relates to the technical field of polyurethane materials, in particular to a handle rubber material for baseball bats. Background technique [0002] A baseball bat is a bat used by a batter to hit the ball in a baseball game. It has a cylindrical shape with a smooth surface and no cross-section joints. At present, the commonly used baseball bats are made of metal materials. The two ends of the metal bats must be sealed. The length of the bat must not exceed 1.07 meters. The diameter of the thickest part must not exceed 7 cm. 2.45 cm. To make it easier to hold the stick, it can be wrapped with cloth, tape or rubber from one end of the grip to a length of 45.7 cm. However, the use of cloth strips, tape or rubber as the wrapping material of the baseball bat handle has poor wear resistance, non-slip resistance, and poor feel, which cannot meet people's needs. Summary of the invention [0003] Based on the technical problems existing in the backg...
