Weather-proof mildew-proof epoxy colored sand and preparation method thereof

The invention discloses weather-resistant mildew-proof epoxy colored sand and a preparation method thereof. The weather-resistant mildew-proof epoxy colored sand is prepared from a component A and a component B, wherein the component A is prepared from, by weight, 20-40 parts of an epoxy resin, 40-70 parts of glass micro-beads, 1-4 parts of fumed silica, 1-5 parts of a diluent, 0-2 parts of a mildew preventive and 0-2 parts of a weather-resistant aid, the component B comprises the following components in parts by weight: 80-90 parts of an epoxy resin curing agent, 1-5 parts of fumed silica, 1-5 parts of a silane coupling agent and 0-3 parts of an accelerant, and the mass ratio of the component A to the component B is (9-11):1. The preparation process is simple, the equipment requirement islow, and the prepared epoxy colored sand has excellent ultraviolet resistance and heat resistance, can reach the zero-grade mildew resistance, and can well meet the indoor home decoration requirement. 本发明公开了一种耐候防霉环氧彩砂及其制备方法，
