Abstract

The invention relates to a preparation method of colored foam glass with adjustable reflectivity. The preparation method comprises the following steps: (1) cleaning, drying and grinding waste glass toobtain waste glass powder; (2) putting the waste glass powder, the furnace slag, the silicon carbide, the glass fiber, the quartz stone, the calcium carbonate and the pigment into a ball milling tank, and performing ball milling until the particle size is 100-200 meshes to form a batch; (3) putting the batch into a mold, putting the mold into a furnace for sintering, adjusting the temperature, and processing to obtain colored foam glass; and (4) plating a nano silicon dioxide sol layer on the surface of the colored foam glass to obtain a finished product. The preparation process is simple, the cost is low, the prepared colored foam glass has good mechanical strength, the light reflection of the glass can be effectively improved, the light reflection rate can be adjusted to a certain extent, and the influence caused by light reflection can be effectively prevented.

Description

technical field [0001] The invention relates to a preparation method of foam glass, in particular to a preparation method of colored foam glass capable of adjusting light reflectivity. Background technique [0002] Building energy conservation is an extremely important policy of the country, and it is a systematic project that benefits the country, the people, and future generations. Strengthening the thermal insulation of buildings plays a direct and practical role in improving people's working and living environment conditions and saving energy. In my country's building thermal insulation projects, high water absorption and poor durability of thermal insulation materials have always been two major problems. It greatly reduces the thermal insulation performance of the material, affects the thermal insulation effect, and increases the energy consumption of the air conditioning system. Moreover, after absorbing water, the insulation layer becomes a water storage layer, which ...
