发明名称 COLORED ROOFING GRANULES WITH INCREASED SOLAR HEAT REFLECTANCE, SOLAR HEAT-REFLECTIVE SHINGLES AND PROCESS FOR PRODUCING SAME
摘要 Solar-reflective roofing granules having deep-tone colors are formed by coating base mineral particles with a coating composition including an infrared-reflective pigment. Color is provided by a colored infrared pigment, a light-interference platelet pigment, or a metal oxide.

主权项 1. A roofing product comprising a mixture of conventional roofing granules and colored infrared reflective roofing granules, the colored infrared reflective roofing granules being selected from the group consisting of (a) granules comprising base particles comprising inert mineral particles coated with a cured first coating composition comprising including a base particle binder and at least one colorant selected from the group consisting of uv-stabilized dyes and granule coloring pigments, the base particles being coated with a cured second coating composition comprising a coating binder and at least one infrared-reflective functional pigment; (b) granules comprising base particles comprising inert mineral particles coated with a cured first coating composition including a base particle binder and at least one reflective white pigment, the base particles being coated with a cured second coating composition including a coating binder, and at least one colorant selected from the group consisting of pigments with near infrared transparency; (c) granules comprising inert base particles with size passing #8 mesh and retaining on #70 mesh coated with a cured coating composition comprising a coating binder and at least one colored, infrared-reflective pigment; (d) granules comprising base particles with size passing #8 mesh and retaining on #70 mesh coated with a cured coating composition comprising a coating binder and at least one colored, infrared-reflective pigment wherein the base particles comprise mineral particles coated with a cured base coating composition including a base particle binder, and at least one reflective white pigment; (e) granules comprising base particles comprising inert mineral particles coated with a cured first coating composition including a base particle binder and at least one reflective white pigment, the base particles being coated with a cured second coating composition including a coating binder, and at least one colorant selected from the group consisting of uv-stabilized dyes and granule coloring pigments; (f) granules comprising inert mineral particles coated with a cured first coating composition including a base particle binder and at least one colorant selected from the group consisting of uv-stabilized dyes and granule coloring pigments to form base particles, the base particles being coated with a cured second coating composition including a coating binder and at least one infrared-reflective functional pigment selected from the group consisting of light-interference platelet pigments including mica, light-interference platelet pigments including titanium dioxide, mirrorized silica pigments based upon metal-doped silica, and alumina; and (g) combinations thereof.
