Background
Rubber floor with good anti-skid performance and comfortable foot feeling is made of rubber, and is widely applied and produced at home and abroad, and the production technical method is mature day by day; meanwhile, many enterprises and technicians also research and trial-produce colored rubber stair treads by utilizing the anti-skid property of rubber; at present, the rubber stair treads with different specifications and surface shapes can be seen in the market, the surface colors of the rubber stair treads can be manufactured by color matching, the stair treads which are the same as the rubber floors can be produced, and due to the successful application of the rubber stair treads with excellent anti-skid performance, the problem of surface anti-skid of a plurality of granite stairs, steel plate stairs and ceramic tile stairs is solved, and the safety of pedestrians walking up and down the stairs is ensured.
However, in the production process of the existing method, the produced product has the defects that: namely, the convex edge of the anti-slip strip at the external corner of the pedal is not provided with warning lines (such as yellow warning lines) with other colors, so that people cannot be reminded of stepping empty due to the fact that steps cannot be clearly distinguished when going upstairs and downstairs.
Later, some famous foreign enterprises adopt a cold bonding method, a groove is reserved at the anti-skid position of an external corner after the tread is vulcanized and formed, and then a vulcanized and cut yellow rubber strip is bonded into the groove by using a universal adhesive, so that the problem that the stair tread does not have a heterochromatic warning line is solved, but the following two defects exist: firstly, the joint of the cold-bonded heterochromatic adhesive tape and the pedal has obvious edge joint marks, which affects the beautiful effect of the appearance; secondly, the firmness of cold bonding is lower than the strength of combined vulcanization, and the heterochromatic adhesive tape is easy to fall off after treading and rubbing by upper and lower footsteps in use.
Disclosure of Invention
In order to solve the problems in the prior art, the invention designs a preparation method of a colored rubber stair tread and the rubber stair tread. The invention designs a special die structure, finds a new production method and solves the existing problems, thereby manufacturing a product which has the advantages of meeting the market demand on product quality, long service life, beautiful appearance and fully meeting the satisfaction of customers.
The invention aims to provide a preparation method of a colored rubber stair tread.
The method comprises the following steps:

the warning line film is placed into a tooth-shaped die cavity formed by the flanges; the main film covers the warning line film, and the main film is molded in one step by die assembly and vulcanization.
In a preferred embodiment of the present invention,
the depth of the sawtooth lines is 0.8mm-1.2mm, the tooth space is 1.8mm-2.2mm, and the tooth crest angle is 90 degrees.
In a preferred embodiment of the present invention,
the flanges are flanges with semicircular sections.
The rib is arranged in the mold, so that the color of the warning line can flow in a set interval in the vulcanization process, and the boundary between the warning line film and the main film is clear and straight; the phenomenon that the colors of two sizing materials are mutually staggered and the connected parts are uneven is avoided. The cross section of the flange is not limited, and the flange can be semicircular, arc-shaped, rectangular and the like, so long as the function of 'clear boundary between the warning line film and the main film in the vulcanization process' can be achieved. In the present invention, a rib having a semicircular sectional shape may be preferable.
In a preferred embodiment of the present invention,
the height of the flange is 1.7mm-1.8 mm; the width of the flange is 2mm-3 mm.
In a preferred embodiment of the present invention,
the vulcanization temperature is 150-170 ℃; preferably 153 ℃ to 163 ℃;
the vulcanization time is 9-15 min.
In a preferred embodiment of the present invention,
the color of the warning line film is different from that of the main film.
In a preferred embodiment of the present invention,
the color of the warning line film is bright and striking, and is preferably yellow or red.
Another object of the invention is to provide a colored rubber stair tread obtained by the method.
The invention can adopt the following technical scheme:
1. preparing a film:
(1) in that
And extruding the adhesive tape with the thickness of 4-5 mm and the width of 300 mm by using an extruder, cooling and cutting into 3065 mm-290 mm-4 mm-5 mm rectangular adhesive films.
(2) In that
The extruder extruded a strip of 1.5 mm in thickness and 50 mm in width, cooled and cut into 3065002466 mm by 15mm by 1.5 mm rectangular sheets.
2. And (3) designing surface grains of the vulcanizing mold: transverse zigzag lines
The middle of the saw tooth line is provided with a saw tooth line with the depth of 1mm, and two sides of the saw tooth line are provided with semi-circular arc-shaped flanges with the height of 1.75 mm.
By the surface design of the model, when the heterochromatic sizing material is pressed to flow in the die cavity during die assembly, the heterochromatic sizing material can be guided by the sawtooth lines and blocked by the semi-circular arc edges to flow transversely in the groove with the width of 15mm, so that the edge of the warning line is ensured to be straight, and the phenomena that the two sizing materials are staggered in color and the connected parts are uneven are avoided.
3. Product die-filling vulcanization
The die filling is divided into two steps: firstly, putting a rectangular film with a warning line into a tooth-shaped die cavity with the width of 15 mm; and secondly, putting the main rubber sheet, and closing the die and vulcanizing.
The invention has the following effects:
1. through special mould structural design and semi-manufactured goods film preparation, let the stair tread that contains the warning line vulcanize out once, the limit portion of warning line has overcome the sizing material diffusion situation moreover, and two kinds of colours link up the straight smooth, and the impression that is the same with cutting.
2. The working time consumption is reduced, the production process is simplified, the product quality is improved, the service life is prolonged, and the product cost is saved.
