    • The present invention features an indelibly colored grout composition and a method of making it. The grout of the invention mixes pre-colored materials such as stone, sand, plastic or ceramic aggregates with a resin binder. In the case of ceramics, the materials are pre-colored and color-fast, so that they resist fading and attack from stains and chemicals. The color-fast materials can be natural or man-made and, if man-made, can be pretreated, and permanently coated. In the case of stone, the natural colors are permanently inherent in the stone matrix and will not fade or leach out. An ultraviolet blocker is also added to the mixture to prevent the binder from yellowing when exposed to sunlight. This admixture also contains an anti-oxidant to prevent the change of color by reason of oxidation. A thixotropic agent is added to provide the desired consistancy, which eases the workability and application of the grout. The mixture may also contain an air-release agent. The pre-colored aggregates may be of a single color; however, it has been found to be advantageous to mix differently colored aggregates with the binder. Such a multi-colored or speckled grout gives the appearance of a single color when viewed from an extended distance; it also blends more readily with multi-colored tiles and masonry materials.
    • 本发明的特征在于一种不可磨灭的色浆组合物及其制备方法。 本发明的浆料将预先着色的材料如石头,沙子,塑料或陶瓷骨料与树脂粘合剂混合。 在陶瓷的情况下,这些材料是预先着色的并且颜色很好,从而防止污渍和化学物质的褪色和侵蚀。 防色素材料可以是天然的或人造的,如果是人造的,可以进行预处理,并且永久涂覆。 在石头的情况下,自然色是永久固有的石基质,不会褪色或浸出。 混合物中还加入紫外线阻挡剂,以防止粘合剂在阳光下暴露时变黄。 该混合物还含有抗氧化剂,以防止由于氧化引起的颜色变化。 添加触变剂以提供所需的一致性,这降低了浆料的可加工性和应用。 混合物还可以含有脱气剂。 预着色聚集体可以是单一颜色; 然而,已经发现将不同颜色的聚集体与粘合剂混合是有利的。 这样的多色或有斑点的浆料从长距离观察时可以看到单一的颜色; 它也更容易与多色瓷砖和砖石材料混合。
