Abstract
The invention discloses an acid and alkali resistant rubber boot vamp rubber compound comprising Chinese No. 1 smoked sheet, butadiene styrene rubber, an accelerant, sulfur, active zinc oxide, stearic acid, an anti-aging agent, high-abrasion furnace black, general carbon black, barium sulfate, a softening agent and a tackifier. A sizing material of the rubber compound prepared by the preparation method has excellent comprehensive indexes such as high strength, good elongation and good flexing resistance; and the sizing material has small physical and mechanical properties on the basis of meeting the acid-base resistance property, and can meet special requirements of an operating environment. The non-split flexing resistance test of finished-product protective boot made of the mixing rubber in a laboratory shows that the flex times of the protective boots is greater than or equal to 3,200,000, and much higher than that of the common acid and alkali resistant rubber boots sold in the market at present while changes of the hardness, the tensile strength and the elongation at rupture of the sizing material soaked by a chemical agent, and the weigh change are small at the same time; and the acid-base resistance property and the resistance to chemical corrosion of the sizing material are good; the sizing material can effectively resist a poor operating condition of a working space on the basis of meeting the acid-base resistance property; and the service life of the finished-product protective boots made of the sizing material can be up to over six months and is prolonged by over 50% in comparison with that of the ordinary commercial product sold in the market under the identical condition.
