The invention discloses a nano-grade modified sintered
brick and a production method thereof. The
brick is prepared from the raw materials of, by weight, 2-4 parts of nano-grade
alumina, 10-15 parts of sculpture clay, 8-12 parts of sea mud, 5-10 parts of
polyvinyl acetate, 4-6 parts of tung oil, 3-6 parts of waste syrup, 1-2 parts of
sodium lauroyl sarcosinate, 3-5 parts of fir
balsam, 4-8 parts of
asbestos fiber, 6-8 parts of an additive, a proper amount of water, and the like. According to the invention, waste
brick slag is adopted as a main
raw material, such that clay resource is saved, production cost is reduced, a waste brick
slag treatment problem is solved, and environment
pollution caused by the waste brick
slag is avoided. The sintered brick provided by the invention has the advantages of high strength, high
bearing capacity,
low density, low heat
conductivity coefficient, wide application range, and good market prospect. The sintered brick meets the requirements of users. The added
polyurethane elastomer has excellent
wear resistance and oil resistance, and is a polar
polymer which can be organically combined with
polypropylene, such that
polypropylene mechanical performances can be improved. The added fluororubber has the characteristics of high-
temperature resistance, oil resistance and the like. With the other fillers other physical performances and
processing performances can be enhanced.
