Embodiment 1
[0049] Mold design: such as Figure 1-3 shown.
[0050] The lower mold of the colored rubber stair treads is provided with a sawtooth pattern; according to the design width of the warning line film, ribs are set on both sides of the sawtooth pattern, and the width of the tooth-shaped mold cavity formed by the two ribs is equivalent to the width of the warning line film; the width is 15mm.
[0051] The zigzag pattern has a depth of 1 mm, a tooth pitch of 2 mm, and a tip angle of 90°.
[0052] The rib is a rib with a semi-circular arc in section; the height of the rib is 1.75 mm; the width of the rib is 2.5 mm.
[0053] The warning line film (yellow) is put into the tooth-shaped mold cavity formed by the rib; the main film (gray) is covered on the warning line film, and the mold is closed and vulcanized once to form.
[0054] Specific preparation process:
[0055] 1. Film preparation:
[0056] (1) in The extruder extrudes a rubber strip with a thickness of 4-5mm and a wid...
[0066]The warning line of the prepared rubber stair tread is yellow, the main film is green, the boundary of the warning line is clear and straight, and after co-vulcanization, the warning line film and the main film are an integral structure, which will not fall off during use.
Embodiment 3
[0068] Mold design is with embodiment 1;
[0069] Preparation process is with embodiment 1;
[0070] The difference is: the vulcanization temperature is 170°C; the vulcanization time is 9 minutes;
[0071] The warning line of the prepared rubber stair tread is green, the main film is gray, the boundary of the warning line is clear and straight, and after co-vulcanization, the warning line film and the main film are an integral structure, which will not fall off during use.

Abstract
The invention discloses a preparation method of a colored rubber stair tread and the rubber stair tread. The method comprises the following steps" arranging sawtooth lines on a lower mold of the colored rubber stair tread; according to a design width of a warning line film, arranging flanges on the two sides of the sawtooth lines, wherein the width of a tooth-shaped mold cavity formed by the two flanges is equal to that of the warning line film; placing the warning line film into the tooth-shaped mold cavity formed by the flanges; covering a main rubber film on the warning line film, and realizing one-step molding through mold closing and vulcanization. A special mold structure is designed, existing problems are solved, the quality of the manufactured rubber stair tread can meet the market requirements, and the rubber stair tread is long in service life and attractive in appearance.
Description
technical field [0001] The invention relates to the technical field of rubber flooring, in particular to a method for preparing colored rubber stair treads and the rubber stair treads. Background technique [0002] The rubber floor made of rubber with good anti-skid performance and comfortable foot feeling has been widely used and produced at home and abroad, and the production technology is becoming more and more mature; at the same time, many enterprises and technicians are also researching and Trial production of colored rubber stair treads; at present, rubber stair treads of various specifications and surface shapes can be seen on the market and used. The successful application of these rubber stair treads with superior anti-skid performance has solved the surface anti-skid problems of many granite stairs, steel plate stairs, and tile stairs, ensuring the safety of pedestrians going up and down stairs. [0003] But in the production technology of existing method, the pr...
