Embodiment Construction

[0017] Below in conjunction with embodiment the present invention is described in further detail.

[0018] The non-asbestos sealed fiberboard formula of the present embodiment consists of:

[0019] 3800-4200 parts of rubber, 480-520 parts of zinc oxide, 1800-2200 parts of white carbon black, 180-220 parts of dibutyl ester, 40-60 parts of stearic acid, 50-70 parts of paraffin wax, 70-90 parts of sulfur, 980-1200 parts of defoaming agent, 1480-1520 parts of glass fiber, 1140-1160 parts of graphite powder, 100-120 parts of anti-aging agent, 320-360 parts of accelerator, the above are parts by weight.

[0020] The formula also adds 1,300-1,700 parts of glass fiber waste, 240-280 parts of ceramic fiber waste, and 1,000-1,200 parts of asbestos-free sealed fiberboard crushed waste, the above are parts by weight. The formula also adds aramid fiber, carbon fiber, polyester fiber, and nylon fiber, and the ratio of adding aramid fiber, carbon fiber, polyester fiber, and nylon fiber is: ...

Abstract

The invention relates to an asbestos-free seal fiberboard and a manufacturing method thereof. The asbestos-free seal fiberboard is composed of 3800-4200 parts of rubber, 480-520 parts of zinc oxide, 1800-2200 parts of white carbon black, 180-220 parts of dibutyl ester, 40-60 parts of stearic acid, 50-70 parts of paraffin, 70-90 parts of sulfur, 980-1200 parts of defoaming agent, 1480-1520 parts of glass fiber, 1140-1160 parts of graphite powder, 100-120 parts of anti-aging agent and 320-360 parts of accelerator. The method comprises the following steps: mixing the zinc oxide, white carbon black, dibutyl ester, stearic acid, paraffin, sulfur, defoaming agent, glass fiber, graphite powder, anti-aging agent, accelerator, toner, waste powder, lime and carbon powder into the rubber according to the formula, pulping, adding the waste fiber to form the master batch, rolling into flakes, vulcanizing the flaky material, and molding the vulcanized rubber to obtain the finished product. The manufacturing method fully utilizes the wastes, and the finished product can maintain the characteristics of high temperature resistance and self lubrication.

Description

technical field [0001] The invention relates to the technical field of sealing parts, in particular to an asbestos-free sealing fiberboard and a manufacturing method thereof. Background technique [0002] An existing Chinese invention patent with the application number CN201210148901.6 titled "Facing Fiberboard and Its Production Process" discloses a facing fiberboard, comprising: a fiberboard; layer. The facing fiberboard provided by the invention uses one-time composite molding technology to compound the facing layer on the slab before hot pressing of the fiberboard, instead of compounding on the fiberboard, which reduces the multi-channel production links of the existing production technology and shortens the production time. The production cycle of facing fiberboard can reduce the production cost. However, its disadvantages are that the fiberboard after composite molding needs to be processed at the edge, and there are many processing leftovers, which is not conducive ...
