Wood-grain silicon PU ball park and production method thereof

Abstract

The present invention provides a wood-grain silicon PU ball park and a production method thereof. The wood-grain silicon PU ball park comprises a prime coat, an elastic layer, a reinforcing layer and a surface layer, wherein the prime coat is coated on the base layer bottom surface, the prime coat, the elastic layer, the reinforcing layer and the surface layer are sequentially arranged from bottom to top, the elastic layer is a silicon PU material layer with a Shore hardness of 40-60 DEG, and a wood-grain layer is further arranged between the reinforcing layer and the surface layer. According to the present invention, the wood-grain silicon PU ball park has characteristics of aging resistance, cracking resistance, bubbling resistance, elasticity, and simple construction.

Description

technical field [0001] The invention relates to the technical field of court materials, in particular to a wood grain silicon PU court and a manufacturing method thereof. Background technique [0002] At present, the common materials for courts are PU, acrylic and EPDM. These materials have insurmountable shortcomings, but also have their own advantages. For example, acrylic has bright colors and is not easy to age and change color. The disadvantage is that it is too hard and too brittle, and it is easy to crack. ; PU is elastic, but it is easy to age and change color, and it is easy to crack and bubble when it is constructed on the cement floor. The most important PU site is not very resistant to dirt. The construction of the EPDM field is simple, and it is not easy to foam and crack, but it is easy to lose particles and age, especially the backboard of the three-division area is often worn down to the concrete floor. Contents of the invention [0003] In view of the abo...
