  The present invention provides, in various embodiments, compositions and methods for strengthening glass without heat or chemical processing of the glass itself. The compositions of the present invention are emulsions comprising polymer colloid particles that are functionalized with an organosilicon compound. The polymer colloid particles can fill surface defects in the glass due to their size being smaller than the surface defects, and the functional groups thereon can react with the surface of the glass to anchor the particles in the defects.

  本发明在各种实施例中提供了无需对玻璃本身进行加热或化学处理即可强化玻璃的组合物和方法。本发明的组合物是由聚合物胶体颗粒组成的乳液，这些聚合物胶体颗粒被有机硅化合物官能化。由于聚合物胶体粒子的尺寸小于表面缺陷，因此可以填充玻璃的表面缺陷，其上的官能团可以与玻璃表面反应，将粒子固定在缺陷处。
