Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: when it rains, due to the rough surface of the runway, it is easy to cause water accumulation on the surface of the runway, and the bottom layer of the runway and the surface layer of the runway are bonded by glue, which will make the adhesion of the glue worse, which is easy to cause The bottom layer of the runway is not bonded firmly to the top layer of the runway, which makes the surface layer bubbling. In severe cases, the surface layer and the bottom layer are separated, affecting the normal use of the runway

Embodiment 1

[0039]A prefabricated runway includes a surface layer 1 and a bottom layer 2, the surface layer 1 is made of foamed plastic, and the bottom layer 2 is made of polyurethane. Grooves 11 are evenly embossed on the surface layer 1 , and the cross section of the grooves 11 is a regular hexagon. Drainage ditch 12 is uniformly arranged on the surface layer 1 , and the drainage ditch 12 communicates with the groove 11 . The surface layer 1 is foamed plastic, and the surface layer 1 has a dense microfoam structure. On the one hand, the overall shock absorption effect of the runway is good, and on the other hand, it can save materials; the bottom layer 2 is polyurethane, which has excellent mechanical properties, such as resistance Grinding, high toughness, good elasticity at low temperature, etc. When it rains, the rainwater enters the groove 11 of the surface layer 1, and then is discharged through the gutter, so as to prevent the rainwater from accumulating in the surface layer 1, ca...

[0048] The structure of a prefabricated runway is the same as in Embodiment 1.

[0049] Each component and its quality of a kind of prefabricated runway of table 2 embodiment 2

[0050]

[0051] The preparation process of the prefabricated runway and the preparation method of the modified sepiolite are the same as in Example 1.

Embodiment 3

[0053] The structure of a prefabricated runway is the same as in Embodiment 1.

[0054] Each component and its quality of a kind of prefabricated runway of table 3 embodiment 3

[0055]

[0056]

[0057] The preparation process of the prefabricated runway specifically includes the following steps:

[0058] Step 1, weighing according to the weight of each component in the formula;

[0059] Step 2: Mix the components of the surface layer and the bottom layer uniformly in step 1, then melt and blend them on a twin-screw extruder, and extrude them into coils at a temperature of 180°C .

[0060] The preparation method of modified sepiolite is as follows: first, add sepiolite into toluene solution and stir, then mix γ-methacryloxypropylmethyldimethoxysilane and absolute ethanol evenly, then add to the Continue stirring in the toluene solution of stone; then the mixed solution is filtered, washed, dried and ball milled to obtain modified sepiolite powder.

Abstract

The invention relates to a prefabricated runway and a preparation method thereof. The runway comprises a surface layer and a bottom layer, grooves are evenly embossed in the surface layer, drainage ditches are formed in the surface layer at intervals, and the drainage ditches are communicated with the grooves; the preparation process of the runway comprises the following steps: 1, preparing a surface layer from the following components in parts by weight: 70-80 parts of ethylene propylene diene monomer, 10-20 parts of a plasticizer, 5-10 parts of a filler, 1-2 parts of a vulcanizing agent, 1-2parts of a foaming agent, 3-4 parts of an accelerant, 2-5 parts of an active agent and 2-3 parts of a flame retardant; the bottom layer comprises the following components in parts by weight: 50-60 parts of polyurethane and 15-25 parts of a plasticizer; and 2, uniformly mixing the components of the surface layer and the bottom layer in the 1, carrying out melt blending on a twin-screw extruder, and extruding at 170-200 DEG C to obtain the coiled material. The grooves and the drainage ditches are formed in the surface layer, rainwater cannot be accumulated on the runway, the surface layer and the bottom layer are prepared in a co-extrusion mode, and the effect of enhancing the connecting strength between the surface layer and the bottom layer is achieved.

Description

technical field [0001] The invention relates to the technical field of runways, in particular to a prefabricated runway and a preparation process thereof. Background technique [0002] Plastic track, also known as all-weather sports track, is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic track has good flatness, high compressive strength, and hardness. The characteristics of proper elasticity and stable physical performance are conducive to the performance of athletes' speed and technology. Plastic track can be divided into prefabricated plastic track, hybrid plastic track, breathable plastic track, composite plastic track, all-plastic plastic track, etc. according to the different materials and construction methods. Prefabricated runways are more and more widely used because of their outstanding characteristics of constant performance, easy installation, and envi...
