Problems solved by technology

Granular adhesives and desulfurized fly ash are used to produce building materials such as water seepage bricks and glass-ceramic, although the utilization rate is high, but due to cost, process and other limitations, it is difficult to be popularized in a large area
[0008] Scholar Wang Chong et al. compounded the finely ground blocky binder with desulfurized fly ash and slag to prepare cementitious materials. The overall strength of cementitious materials showed a decreasing trend
[0009] Scholar Amit Rai et al. crushed air-cooled block binder and desulfurized fly ash into concrete aggregates. The binder and desulfurized fly ash aggregates meet the requirements of the IS 3 83:1990 standard, and suggested that it can be Used in nonstructural concrete, but the effect of this aggregate on concrete properties has not been studied
And the adhesive is flammable and explosive, which will damage the equipment

Abstract

The invention discloses a preparation method and application of a desulfurized fly ash energy-saving environmental-friendly building material adhesive. The desulfurized fly ash energy-saving environmental-friendly building material adhesive consists of the following components in parts by weight: cation water, fatty alcohol polyethylene oxide ether sodium sulfate salt, succinic anhydride, N-cyclohexyl para toluene sulfonamide, N,N-dimethyl-p-nitrosoaniline, 1-amino-5-hydroxyl-4-[(1-methyl propyl] amino]-8-nitro-9,10-anthraquinone, 1-phenylamino-4-hydroxyanthraquinone, p-Methylthiobenzyl alcohol, gold nanoparticles, 4,4'-diamido-triphenylmethane, succinic anhydride, 4,4'-(3,3'-dichlorobiphenyl-4,4'-dinitrogen)di(4,5-dihydro-5-oxo-1-phenylpyrazole-3-formic acid) diethyl ester, benzotriazole-1-tri(trimethylamino)-trifluorophosphate, N-(2-benzimidazolyl) methyl carbamate and alpha-bromonaphthalene. The preparation method has the advantages that the adhesive is prevented from saponification, the surface tension of mixtures is reduced, and the mixtures can be relatively solidly adhered to one another; the adhesive has the advantages of stable chemical properties, wide application and high surface cleanliness ratios of molded structures.

Description

technical field [0001] The invention belongs to the field of new building materials, and in particular relates to a preparation method and application of an energy-saving and environment-friendly building material adhesive for desulfurized fly ash. Background technique [0002] The deficiencies of existing technology: [0003] Scholar Li Junhong used granular binder, desulfurized fly ash and tin slag to burn silicate wall material clinker in a vertical kiln, and mixed an appropriate amount of binder in the raw material to burn out Silicate clinker with good stability, normal setting time and high early strength. But the adhesive is toxic and pollutes the environment. [0004] Scholar Li Wenbin et al. used adhesives and desulfurized fly ash, nickel slag, and coal-research stone ingredients to burn clinker on a shaft kiln, and used fly ash as a mixture to produce ordinary silicate new wall materials, which not only can The reduction of environmental pollution can also reduc...
