自1984年起,我们在研制溶剂型橡胶改性沥青的基础上,进行了水乳型橡胶改性沥青配方和生产工艺的研究,现简介如下: 1.配方经多次试验调整,确定配方为10号沥青300,渣油沥青90,橡胶片(颗粒)30,肥皂1.6～2.0,水玻璃3.2～4.0,烧碱1.6,自来水400,滑石粉100(或适量)。 2.生产工艺先将橡胶切成小颗粒或片状,加入已脱水的渣油沥青中,在150℃左右的温度下溶解(约需4小时),成为高分子溶液,然后
Since 1984, based on the development of solvent-based rubber modified asphalt, we have carried out research on the formula and production process of the water-emulsion-modified rubber asphalt, and are now summarized as follows: 1. The formulation has undergone multiple test adjustments to determine the formula as 10th bitumen 300, residual bitumen 90, rubber sheet (particles) 30, soap 1.6-2.0, water glass 3.2-4.0, caustic soda 1.6, tap water 400, talc 100 (or moderate). 2. Production process The rubber is first cut into small particles or flakes, added to the dehydrated residue asphalt, and dissolved at a temperature of about 150°C (about 4 hours) to become a polymer solution, and then
