Abstract

The invention discloses a running board bottom surface coating. The running board bottom surface coating comprises the following components in parts by weight: 60-70 parts of thermosetting resin, 20-30 parts of VAE emulsion, 3-6 parts of calcium stearate, 0.1-0.5 part of calcium persulfate and 0.5-1.5 parts of ammonium chloride. The coating is mainly different from a running board top surface layer coating in wear resistance and low friction coefficient, the running board bottom surface coating pays more attention to the strength of the running board and the fatigue resistance under the actionof alternating stress, the curing shrinkage rate of the running board bottom surface coating is close to that of the surface layer coating, and the internal stress of the whole board is balanced. According to the coating, the thermosetting resin is used as a main body, the VAE emulsion is compounded, the brittleness of the thermosetting resin is improved by utilizing the characteristics of good flexibility, strong toughness, low temperature resistance, weather resistance, stress cracking resistance, heat sealability, cohesiveness, rubber-like elasticity, ozone resistance and the like, and themechanical property of the thermosetting resin is improved. The coating is applied to the bottom surface of the running board, so that the static bending strength and the impact resistance of the running board can be improved, and the bottom surface and the top surface of the running board are balanced in stress and difficult to bend.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a running board bottom surface coating and a preparation method thereof, and a running board. Background technique [0002] The bottom plate of the treadmill is called a running board, and its base material is generally medium-density fiberboard. In the past, the bottom surface of the running board was pasted with a layer of melamine-impregnated paper like the top surface. Since the melamine-impregnated paper has a low elongation at break after curing, the bottom of the running board is in use due to the weight of the person and the impact force during running. It is in a stretched state, causing the running board to break, so this method is rarely used at present. At present, the more commonly used bottom surface treatment methods of running boards are: paste PU moisture-proof paper or paste PVC film. This solves the problem of decreased strength of the running board....
