Problems solved by technology

The existing artificial turf needs to be fixed on the ground by external force, and must be filled with fillers such as quartz sand and rubber particles to improve the cushioning performance of the artificial turf. Most of the rubber particles are broken particles from waste tires, cables, etc., which bring great harm to the environment. There are adverse effects, and at the same time, the cost is increased. At the same time, there are defects in odor and other aspects. People inhale volatile odors and easily affect health.

Embodiment 1

[0049] refer to figure 1 and combine figure 2 , an artificial turf support pad, comprising a main backing plate 1; the thickness of the main backing plate 1 is 20mm;

[0050] The upper surface of the main backing plate 1 is provided with several circular upper protrusions 11 and upper grooves 12; the circular upper protrusions 11 protrude upward and are evenly spaced on the upper surface of the main backing plate 1; The upper groove 12 is formed by connecting the depressions between two adjacent circular upper protrusions 11;

[0051] The lower surface of the main backing plate 1 is provided with several hexagonal lower protrusions 13 and lower grooves 14; the hexagonal lower protrusions 13 protrude downward and are evenly spaced on the lower surface of the main backing plate 1; The lower groove 14 is formed by connecting the depressions between two adjacent hexagonal lower protrusions 13;

[0052] The thickness of the circular upper convex part 11 is 0.2 mm, and the thick...

Abstract

The invention discloses an artificial turf supporting pad and a preparation method thereof. The artificial turf supporting pad comprises a main pad plate. Multiple upper convex parts and upper grooves are arranged on the upper surface of the main pad plate. Multiple lower convex parts and lower grooves are arranged on the lower surface of the main pad plate. The main pad plate is further provided with vertically-through drain holes. The drain holes are evenly distributed in the main pad plate. The drain holes are communicated with the upper grooves and the lower grooves. The preparation method of the artificial turf supporting pad includes the steps that 1, materials are prepared by weight; 2, foamed polypropylene particles are prepared through a kettle pressing method or an extrusion method; 3, the foamed polypropylene particles obtained in the step 2 are subjected to hot press molding through a mold, and the artificial turf supporting pad is obtained. The artificial turf supporting pad has good buffer performance; the drain grooves and the drain holes are formed, so that good drain performance is achieved; the preparation method achieves one-time molding, the artificial turf supporting pad has good buffer performance, and preparation efficiency is high.

Description

technical field [0001] The invention relates to an artificial turf support pad and a preparation method thereof, belonging to the technical field of industrial chemistry. Background technique [0002] With the promotion and development of outdoor sports, people like the natural environment, and because the natural lawn is affected by the seasons, it is easy to wither in autumn and winter, so the artificial lawn is characterized by easy installation and durability, and has gradually been widely used. The existing artificial turf needs to be fixed on the ground by external force, and must be filled with fillers such as quartz sand and rubber particles to improve the cushioning performance of the artificial turf. Most of the rubber particles are broken particles from waste tires, cables, etc., which bring great harm to the environment. Unfavorable influence has come, increased cost simultaneously, simultaneously, all have defective aspects such as odor property, and people's in...
