| titleOfInvention | A method for treating sea sand with recycled polyurethane |
| abstract | The invention discloses a method for treating sea sand by using recycled polyurethane, which is characterized in that an aqueous solution of a silane coupling agent containing amino groups on the molecule is added to a mixing material mixer, untreated sea sand is added, and after thorough stirring, solids are filtered out. particles; add the mixture containing polyol, urea group and isocyanate into water to make a solution, add the obtained solid particles into the solution, and after thorough stirring, filter out the solid particles; mix the water-based asphalt with the obtained solid particles, fully Stir. The preparation method of the invention is simple, the whole process is carried out in an aqueous environment, the cost is low, and the processed sea sand has better performance and can be used for building materials. |
