Embodiment Construction

[0016] Unless defined otherwise, all technical and scientific terms used herein have the meaning commonly understood by one of ordinary skill in the art.

[0017] The preparation process of the cork floor of the present invention is described in detail below.

[0018] Cook the harvested cork or oak bark at a water temperature of 100°C to 120°C for 1 to 2 hours to fully soften and expand the bark. After cooking, the volume of the cork can increase by 20%, and the elasticity is better. The cooking process can also remove impurities, organic matter and organic volatiles in the bark, and can also kill insect eggs and bacteria to meet environmental protection requirements.

[0019] The boiled bark is taken out and dried, and cut into cork chips with a thickness of 10 to 30 mm with a slicer.

[0020] The cork chips are ground into coarse particles with a particle size of 8 to 15 mm, and then cone milled, vibrating screen and air selection to obtain cork particles with a particle si...

Abstract

The invention provides a preparation method of a cork wood ground system for sports places. The preparation method comprises the following steps: (1) preparing cork wood granules by using phellem or oak bark as a raw material; (2) mixing the cork wood granules with single-component polyurethane glue; (3) spreading a mixture obtained in step (2) on foundation ground. The invention also provides thecork wood ground system prepared through the preparation method. The cork wood ground system provided by the invention adopts pure ecological cork wood granules, is environmentally friendly, has no peculiar smell and is suitable for physical exercise places such as a basketball court, a badminton court, a volleyball court, a playground, a footpath, a path, a children's playground, a sports instrument zone, a fitness room, a track-and-field ground track, a retirement home, a plaza and an indoor activity room.

Description

technical field [0001] The invention relates to ground and its preparation method, especially the ground system and its preparation method for sports grounds. Background technique [0002] Cork is made from the veneer of trees in the Quercus family (cork or oak). Quercus trees usually grow in mountain forests at 32° to 35° north latitude and 400 to 2,000 meters above sea level. Cork consists of many flattened cells arranged radially. The space between two adjacent cells consists of five layers, two of which are fibrous, followed by two suberized layers, and a woody layer in the middle. There are more than 40 million cells in every cubic centimeter of cork, and the cells are filled with about 50% air. Therefore, the cork material is light and soft, elastic and eco-friendly. In addition, cork materials are impermeable, decay-resistant, chemically resistant, wear-resistant, and have excellent heat insulation, sound insulation, and electrical insulation. Chemically, cork is...
