Problems solved by technology

This type of sports field has the following main disadvantages: (1) The plastic particles in the elastic surface layer are prone to discoloration and aging, and are prone to cracking and cracking under extreme weather conditions, with a short service life; (2) The synthetic material surface of the traditional sports field In the actual use process, the physical properties of the layer are difficult to meet the standards, and the user cannot be well protected; (3) the raw materials are not environmentally friendly, and the adhesives or solvents used contain more or less toxic substances; (4) the cost is too high, Difficult to promote; (5) The construction period is long and the labor intensity of workers is high
At present, there is no sports floor on the market that only uses ETPU as the surface layer.

Embodiment 1E

[0025] Example 1 ETPU prefabricated sports floor

[0026] Such as figure 1 The ETPU prefabricated sports floor shown is mainly composed of a surface layer 1, a glue layer 2 and a base layer 3 arranged in sequence from top to bottom. The surface layer 1 is an ETPU prefabricated block layer formed by splicing a plurality of ETPU prefabricated blocks 4, and the thickness of the surface layer 1 is 8-25mm. The base layer 3 is a concrete or asphalt poured ground. The glue layer 2 is paved by a one-component polyurethane adhesive, and other glues in the field can also be used for paving the surface layer 1 firmly on the base layer 3 . The ETPU prefabricated block 4 is a rectangle, and can also be other shapes convenient for splicing, such as hexagons.

Embodiment 2

[0027] Example 2 Preparation of ETPU prefabricated sports floor

Embodiment 1

[0028] The ETPU prefabricated sports floor of embodiment 1 is obtained according to the following steps:

[0029] 1) Preparation of TPU shaped plate 5: TPU granules are made into TPU shaped plate through injection molding process. Such as figure 2 As shown, the TPU shaping board 5 is a grid plate of a rectangular or other shape that is convenient for splicing multiple pieces. The grid can be rectangular, honeycomb, circular, polygonal or other shapes. Currently, there are various molds available on the market, which can produce There are many kinds of stereotyped plates with different grid shapes. Several support columns 5a are arranged on the lower surface of the TPU shaped plate 5, and the support columns 5a may be in the shape of a cylinder, a square column, a polygonal column, a trapezoidal column, and the like. The support column structure on the TPU shaped board is extremely stable and resilient, which can perfectly meet the user's sports experience. The lower surfac...

Abstract

The invention discloses an ETPU (expanded thermoplastic polyurethane) prefabricated type sport floor which comprises a surface layer, a glue layer and a foundation layer. The surface layer, the glue layer and the foundation layer are sequentially arranged from top to bottom, the surface layer is an ETPU prefabricated block layer, the thickness of the surface layer is 8-25 mm, and the foundation layer is a concrete or asphalt poured ground. The invention further discloses a method for preparing the ETPU prefabricated type sport floor. The method includes steps of 1), preparing TPU (thermoplastic polyurethane) molding plates from TPU particles by the aid of injection molding processes; 2), preparing ETPU prefabricated blocks from the TPU molding plates, which are prepared at the step 1), bythe aid of physical foaming processes; 3), thoroughly cleaning the surfaces of the foundation layer and paving polyurethane adhesive on the foundation layer to obtain the glue layer; 4), paving the ETPU prefabricated blocks, which are prepared at the step 2), on the glue layer. The TPU molding plates are grid plates, and a plurality of support columns are arranged on the lower surfaces of the TPUmolding plates.

Description

technical field [0001] The invention belongs to the technical field of building applications, and in particular relates to an ETPU prefabricated sports floor and a preparation method thereof. Background technique [0002] With the continuous and rapid development of the economy and the continuous improvement of people's living standards, elastic sports venues are getting more and more attention in people's lives. Covering the original concrete or asphalt sports venues with synthetic materials can suppress dust and improve sports conditions. . [0003] The surface layer of traditional sports field synthetic materials is mainly based on recycled waste rubber particles, EPDM particles, oily PU materials, water-based PU materials, acrylic, polyurethane single-component or multi-component adhesives. This type of sports field has the following main disadvantages: (1) The plastic particles in the elastic surface layer are prone to discoloration and aging, and are prone to cracking...
