The present invention is through substantial amounts of experimentation, non-burning brick to the present invention by adding a small amount of neck phthalic acid dibutyl ester
Comprcssive strength after molding has strong influence, by series of experiment research, finds when neck phthalic acid dibutyl ester adds
When amount is 0.1 weight portion, the comprcssive strength after the non-burning brick molding of the present invention can be made to reach maximum, below or above this weight
Part, all can reduce the comprcssive strength after the non-burning brick molding of the present invention to a certain extent.
The present invention is through substantial amounts of experimentation, by the research to various gel rubber materials, thus prepares the present invention and exempts from
Bake bricks the gel rubber material used, coordinate casting non-burning brick every intensity of preparing of waste residue after treatment and resistance to water all to obtain
Arrive great raising, and under specific briquetting pressure and under specific curing temperature, it is possible to promote non-burning brick further
Combination property, prepared non-burning brick light weight, insulation, sound insulation, water absorption rate are low, energy-conserving and environment-protective, especially comprcssive strength obtain
Promote greatly, it is possible to meet the demand of more occasion.
The method have the benefit that the present invention's is non-burning brick by potter's clay is coordinated the casting added with the blended process of bauxite
Make waste residue and gel rubber material, while ensureing and improving non-burning brick intensity, reduce the incorporation of other aggregate, decrease ore deposit
Producing the exploitation of resource, reduce non-burning brick cost, production technology is simple, and low cost, by the synergism between each material, makes
The non-burning brick intensity that must prepare is high, heat conductivity is low, effect of prestressed the best, energy-conserving and environment-protective, meets the needs of architectural engineering, symbol
The demand that cyclization is protected；By casting waste residue is recycled, decrease environmental pollution, protect ecological environment；The system of the present invention
Preparation Method had the most both been saved man-hour, had been saved the energy, reduced again cost.
