Abstract
The invention aims at solving the technical problems that the environment is polluted, the production cost is high and the product can not be used as the color micro-surface cementing material due to poor performance in the process for preparing the existing color modified emulsion discolored asphalt, and provides a method for preparing color liquid SBS modified emulsion resin which consists of the following raw materials: light color resin emulsion, liquid SBS modifier, inorganic pigment 307 chrome molybdenum red pigment or SGC-M chrome green pigment, pigment dispersant polycarboxylic acid sodium salt or polyacrylic acid ammonium salt. The method comprises the steps of: when in preparation, adding the raw materials into a reactor, maintaining the temperature of the reactor within 20 DEG C to 30 DEG C, adding phosphoric acid to adjust the pH value of the system to be 2.5-4.5, uniformly stirring the system and then obtaining the high-performance color liquid SBS modified emulsion resin. The method has the advantages of simple preparation process, low production cost and non-toxic harmless performance, can be constructed at room temperature, and can prepare the high-performance color micro-surface cementing material to be used for heavy traffic roads by choosing appropriate modifier.
Description
technical field [0001] The invention relates to a preparation method of modified emulsified resin used in traffic roads, in particular to a preparation method of colored liquid SBS modified emulsified resin. Background technique [0002] At present, there are mainly the following forms of colored pavement at home and abroad: 1. Concrete pavement with petroleum resin as cement; 2. Concrete pavement with decolorized asphalt as cement; 3. Synchronous gravel pavement with two-component resin as cement; 4. Color paint to spray the road surface. Petroleum resin and decolorized asphalt need to be heated and melted, and the concrete pavement construction equipment and production costs using it as a cementing material are relatively high, and will produce more environmental pollutants; the simultaneous crushed stone pavement construction process with two-component resin as a cementing material Complicated, low efficacy, high cost; colored paint spraying road surface has short servic...
