Abstract
A rubber sheet with a mesh cloth as its sandwich is composed of two rubber sheets and a central mesh cloth. Its preparing process includes such steps as plasticizing natural rubber and synthetic rubber, adding filler, pugging, adding sulfurizing agent, forming flakes, cooling, laying aside, heating or extruding, calendering to become rubber sheet, adhering both rubber sheets with a mesh cloth, pressing and sulfurizing.
Description
Technical field
The present invention relates to a kind of rubber sheet stock and preparation method thereof, specifically, is that a kind of centre accompanies rubber sheet stock of eyelet fabric and preparation method thereof
Background technology
Tradition rubber process technology adds filler and carries out mixingly with natural rubber and the synthetic rubber back of plasticating, and goes out the 10mm sheet after then adding vulcanizing agent, through the supercooling placement more than 72 hours.Heat refining scribing or extrude again, one in the glue face by calender removing from mould certain thickness (1.5mm) shape, glazing or delustring again, the sheet rubber of light face or line face is promptly made in the most laggard digester (-tor) sulfuration.There is following defective easily in the rubber of this traditional method for making: shrink greatly before (1) sulfuration, the difficult control of thickness thickens weightening finish and causes waste of material, and shrinkage phenomenon is also arranged during sulfuration, has influenced the sizing material consumption.(2) main physical properties is poor: anti-deflection 80,000 times, breaking strength 12Mpa permanent deformation 28%.This is the numerical value of domestic and international critical field.But this performance directly influences the service life of product.(3) product surface is prone to bubble, sand holes, particle, asperities, influences presentation quality, so that defective products is many, and the percentage of A-class goods is generally at 95% lower limit.
Summary of the invention
Goal of the invention of the present invention is to overcome the defective that prior art exists, and saves rubber raw materials, improves the quality, increases benefit, and a kind of rubber sheet with sandwiched screen cloth and preparation method thereof is provided.
Rubber sheet with sandwiched screen cloth of the present invention is made of two TR thin rubber sheets, it is characterized in that: gummed one deck eyelet fabric between two sheet rubbers.
The method that the present invention makes rubber sheet with sandwiched screen cloth is as follows: with natural rubber and synthetic rubber plasticate the back add filler carry out mixing, then add vulcanizing agent after, form thin slice, cooling is placed more than 24 hours; Heat refining slice or crowded sheet again are by the certain thickness flat sake rubber sheet stock of calender removing from mould; Will with the reverse side of the identical shaped eyelet fabric of rubber sheet stock and two rubber sheet stocks brush coating water respectively, eyelet fabric is attached among the two-layer glue face, carry out pressing, glazing or delustring again, at last by the digester (-tor) sulfuration rubber sheet with sandwiched screen cloth.
Rubber sheet with sandwiched screen cloth of the present invention: the production cycle shortens 48 hours than traditional rubber, and thickness can reduce 8% than traditional rubber, and weight can alleviate 10%, can save rubber 20% than traditional rubber.Physical and mechanical properties greatly improves: anti-deflection reaches 200,000 times, improves 150% than traditional rubber, and breaking strength 36Mpa improves 200% than traditional rubber, and permanent deformation reaches 14% than traditional rubber reduction by 100%.It is very attractive in appearance that outward appearance zero defect, surface set off the dark line of clear thunder word that.The quality percentage of A-class goods reaches more than 99.5% and rises 5.5 percentage points than traditional rubber.
Rubber sheet with sandwiched screen cloth preparation method of the present invention, technology is simple, produces quick, reliable, safety.The eyelet fabric that adopts is nontoxic and process is pollution-free, is very good product and preparation method.
Description of drawings
Fig. 1, for rubber sheet with sandwiched screen cloth structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
Embodiment with natural rubber and synthetic rubber plasticate the back add filler carry out mixing, then add vulcanizing agent after, go out the thin slice of 10mm thickness, cooling is placed more than 24 hours.Heat refining slice or crowded sheet are the flat sake of 0.6mm by calender removing from mould thickness again.The reverse side of eyelet fabric that will be identical shaped with the rubber sheet stock (thick 0.25mm) and two rubber sheet stocks is brush coating water respectively, dry back is attached to eyelet fabric among the two-layer glue face, carry out pressing, glazing or delustring again, at last by digester (-tor) sulfuration rubber sheet with sandwiched screen cloth as shown in Figure 1.
Rubber sheet with sandwiched screen cloth of the present invention especially is suitable for linings such as galosh (rubber boot), tent.
Claims (2)
1, a kind of rubber sheet with sandwiched screen cloth comprises two TR thin rubber sheets, it is characterized in that: gummed one deck eyelet fabric between two TR thin rubber sheets.
2, a kind of method of making the described rubber sheet with sandwiched screen cloth of claim 1, its manufacturing process is: with natural rubber and synthetic rubber plasticate the back add filler carry out mixing, then add vulcanizing agent after, form thin slice, cooling is placed more than 24 hours; Heat refining slice or crowded sheet again are by the certain thickness flat sake rubber sheet stock of calender removing from mould; Will with the reverse side of the identical shaped eyelet fabric of rubber sheet stock and two rubber sheet stocks brush coating water respectively, eyelet fabric is attached among the two-layer glue face, carry out pressing, glazing or delustring again, at last by the digester (-tor) sulfuration rubber sheet with sandwiched screen cloth.
