Problems solved by technology

Among them, due to the large randomness of the paste particles, there will always be some particles that are not firmly bonded and form threshing; direct spraying of glue and particle mixture and direct spraying of pure glue, although the threshing defect has been solved to a certain extent, However, affected by the technical level, experience and carefulness of the construction personnel, it is difficult to ensure the consistency and uniformity of the pavement even if the workers are very skilled.
There is also a method for making the anti-skid surface layer, which is to form concave-convex patterns by directly acting on the mold embossing on the anti-skid surface glue. Although this method can avoid the problems of threshing and unevenness, it has high labor intensity and low work efficiency. , large mold consumption, high processing cost and other disadvantages, especially the selection of release agent is not easy to master, and the phenomenon of inability to release the mold often occurs during on-site construction

Embodiment 1

[0029] Embodiment 1: Pave the plastic runway, the thickness of the elastic bottom layer of the plastic pavement is required to be 10 mm, and the thickness of the anti-skid surface layer is 3 mm. Clean up the ground of the runway base; pave the elastic bottom rubber on the basic ground, the thickness of the elastic bottom rubber is 10 mm, and form a 10 mm thick elastic bottom layer after natural curing for 24 hours; pave the 2mm non-slip surface rubber on the elastic bottom layer, Then, use an air compressor to compress the air to 0.8 Mpa, select a nozzle with a nozzle diameter of 0.3 mm, and spray the compressed gas on the surface of the anti-slip surface through the pipeline and the nozzle. The distance between the nozzle and the anti-slip surface is 20mm. The moving speed is 4 m / s. With the movement of the nozzle, a number of parallel grooves are carved on the non-slip surface adhesive. The interval between the grooves is 3mm. After the engraved lines are completed, they will...

Embodiment 2

[0030] Embodiment 2: Pave the kindergarten activity field, requiring the thickness of the elastic bottom layer of the plastic pavement to be 30 mm, and the thickness of the anti-skid surface layer to be 2 mm. Clean up the basic ground of the event site; pave the elastic bottom rubber on the basic ground, the thickness of the elastic bottom rubber is 30 mm, and form a 30 mm thick elastic bottom layer after natural curing for 24 hours; pave the 1.4mm non-slip surface on the elastic bottom layer Glue, then pressurize the water to 0.2MPa through the water pump, select a nozzle with a nozzle diameter of 0.35 mm, spray the water on the surface of the non-slip surface through the pipeline and the nozzle, the distance between the nozzle and the non-slip surface is 10mm, and the nozzle moves The speed is 3 m / s, and the nozzle moves left and right while moving back and forth. With the movement of the nozzle, a number of wavy grooves are carved on the non-slip surface adhesive. The groove...

Embodiment 3

[0031] Embodiment 3: Pave the basketball field, require the thickness of the elastic bottom layer of the plastic pavement to be 8 millimeters, and the thickness of the anti-skid surface layer to be 3 millimeters. Clean up the basic ground of the activity site; pave the elastic primer on the basic ground, the thickness of the elastic primer is 8 mm, and form an 8 mm thick elastic bottom layer after natural curing for 24 hours.

[0032] Preparation of non-slip surface glue:

[0033] Part A consists of the following raw materials:

[0034] Polyether polyol JH2000D 200Kg, polyether polyol JH1000D 200 Kg, polyisocyanate 140 Kg. After fully mixing polyether polyether polyol JH1000D and polyether polyol 2000D, add polyisocyanate at room temperature, raise the temperature to 80°C, react for 120 minutes, and pack for use.

[0035] Component B is composed of the following raw materials by mass: polyether polyol JH3030D 270 Kg, green paraffin wax 250 Kg, polyether polyol JH 403 7 Kg, tal...

Abstract

The invention discloses a preparation method of a plastic pavement for sports places. The preparation method comprises the following steps of a, basic ground cleaning, b, elastic base plastic paving, c, antiskid surface plastic paving: paving antiskid surface plastic on the cured elastic base plastic layer, d, pressure fluid medium-based pattern engraving: spraying a pressure fluid medium by a nozzle so that groove-shaped patterns are formed by movable injection impact on the antiskid surface by the nozzle, and carrying out natural curing at a normal temperature for 24hs so that the antiskid surface layer with the groove-shaped patterns is formed. The plastic pavement solves the problem that the traditional plastic pavement particles easily fall off and have poor uniformity. Compared with the existing molding method, the preparation method provided by the invention has the advantages of high work efficiency, operation easiness and low processing cost, prolongs a plastic pavement service life and improves plastic pavement appearance aesthetic properties.

Description

technical field [0001] The invention relates to a method for preparing a plastic pavement for sports venues, belonging to the technical field of sports venue construction. Background technique [0002] The plastic pavement of sports venues includes the plastic pavement laid on the ground of track and field, track, court, kindergarten playground, school playground and so on. Plastic paving has the advantages of good elasticity, anti-slip, shock absorption, good flatness, stable performance and beautiful appearance. It has been widely used in sports competition venues, fitness activity venues, school sports venues, etc. It is currently the best floor material for outdoor sports venues. The main structure of the plastic pavement is composed of an anti-slip surface layer and an elastic bottom layer. The elastic bottom layer is used to provide good elasticity and shock absorption, and the anti-slip surface layer plays the role of wear resistance and anti-skid. At present, the co...
