Abstract
The invention discloses a high-durability rubber apron material which is prepared from the following raw materials in parts by weight: 20-30 parts of silicon rubber, 40-50 parts of nitrile-butadiene rubber, 5-10 parts of graphite powder, 2-4 parts of dioctyl terephthalate, 12-15 parts of diatomite, 12-14 parts of porcelain clay, 2-3 parts of PEG (Polyethylene glycol) 4000, 2-4 parts of Rhine wax, 1-2 parts of sulphur, 2-3 parts of polyamide fiber, 1-2 parts of ammonium polyphosphate and 23-28 parts of modified filler. The high-durability rubber apron material is uniform in mixing and good in compatibility; due to the addition of the porcelain clay and the modified filler, the high-durability rubber apron material is high in durability and long in service life.
Description
