Problems solved by technology

However, when the silicate cement is in service for a long time under this working condition, due to the multiple effects of cavitation, chemical corrosion and physical abrasion, the corrosion and wear on the surface of the cement is more serious, and the consumption of cement between some brick joints is relatively large, showing concave shape
In addition, due to the heat and cold transformation of the pipe wall when the slurry solution is transported, the cement has a certain thermal shock damage, which has a great impact on its bonding performance, and some of the cement has cracks in the glue layer, which leads to the leakage of the slurry solution The phenomenon

preparation example Construction

[0058] In other examples of the present invention, the preparation method of the above-mentioned silicate composite cement comprises the following steps:

[0059] 1) The liquid furfural phenol resin, reactive diluent cyclohexanone, ethyl sulfate and potassium water glass are mixed and reacted in a stirring state by weight percentage to prepare component A;

[0060] 2) Mixing the inorganic rigid particles by weight percentage to obtain component B;

[0061] 3) The component B is mixed with the component A and stirred for 10-20 minutes to obtain a silicate composite cement.

[0062] In a preferred embodiment, in step 1), the liquid furfural phenol resin is added to the reaction kettle and stirred, and the temperature is increased to 55-60°C, and then the reactive diluent cyclohexanone is added, mixed and stirred evenly, and the heat preservation reaction 1- 2 hours, such as 1.5 hours; keep the temperature constant, continue to stir and add ethyl sulfate, react for 10-15 minutes...

Embodiment 1

[0081] 1) Add 15wt% liquid furfural phenol resin in the chemical reaction kettle, start the stirring equipment, increase the temperature to 55°C, add 5wt% cyclohexanone (reactive diluent), mix and stir evenly, keep warm for 1.5 hours Keep the temperature constant and continue to stir, and add 6wt% ethyl sulfate in the chemical reaction kettle, react for 10min; add 74wt% potassium water glass and continue to stir for 15min after cooling down to room temperature, and prepare component A;

[0082] 2) Mix dry 20wt% sodium aluminosilicate, 7wt% silicon micropowder, 20wt% graphite and 30wt% asbestos powder, grind to 600 mesh and add 2wt% aluminum powder, 11wt% fluosilicic acid Sodium and 10wt% glass fiber are made into mixed filler as component B for later use;

[0083] 3) When heated to 50°C, add 50 wt% of component B to 50 wt% of component A in proportion, and stir in a mixer for 20 minutes to obtain a modified silicate composite cement;

[0084] 4) After applying the obtained si...

Abstract

The invention belongs to the technical field of chemical anticorrosion daub and particularly relates to furan resin modified silicate composite daub and a preparation method thereof. The silicate composite daub is prepared from raw materials comprising the following ingredients by weight percentage according to 100wt% of the total weight of all the ingredients: 50-60wt% of an ingredient A and 40-50wt% of an ingredient B, wherein the ingredient A is prepared from the following reactive materials by weight percentage according to 100wt% of the total weight of all the reactive materials: 64-74wt%of potash water glass, 15-20wt% of liquid furfural phenol resin, 6-8wt% of ethyl sulfate and 5-8wt% of cyclohexanone; the ingredient B is a mixture of inorganic rigid particles. According to the silicate daub, the effects of wear resistance, acid corrosion resistance and thermal shock resistance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of chemical anticorrosion mastic, and in particular relates to a furan resin-modified silicate composite mastic and a preparation method thereof. Background technique [0002] In the existing technology, there has been a successful research and development of circulating fluidized bed fly ash "one-step acid dissolution method" to extract metallurgical grade alumina technology by making full use of the "high aluminum and gallium-rich" Zhungeer coalfield. reports. This project is of great significance to alleviate the shortage of bauxite resources and ensure the safety of aluminum industry resources. [0003] In the dissolution process of the "one-step acid dissolution method" slurry solution, it is necessary to store and transport the slurry after dissolution. The working conditions at this stage are relatively harsh: the internal working temperature of the tank is relatively high (within the range of 120-15...
