Problems solved by technology

[0005] As can be seen from the above-mentioned existing colored cement production process, its main disadvantages are: (1) the production form is mainly intermittent, the production cycle is long, and the production efficiency is low. It takes about 8 hours for the process of heating and stirring once feeding, heat preservation and development. hour time
(2) A lot of production equipment is required, and the device is relatively large. Generally, 3 to 4 heating and stirring tanks, colloid mills, multiple specialized delivery pumps, long insulation pipelines and online metering equipment are required.
(3) The investment in equipment is large and the production cost is high. Due to the high viscosity of materials, various equipment needs heating, temperature control and heat preservation facilities, and the failure rate of equipment is high.

Embodiment 1

[0022] according to image 3 The equipment and method shown, petroleum resin and SBS are fed into the extruder 12 through the feeding port 10, and the refined oil extracted from the lubricating oil solvent is fed into the extruder 12 through the feeding port 11. 10 cycles of mixing, extruding twice, and then cooling to obtain the final color cement product. The main properties of the product are shown in Table 1.

Embodiment 2

[0024] According to the process of Example 1, the extruder 12 was operated at 170° C. and 2 MPa, and the output temperature was directly lowered to obtain the final color cement product. The main properties of the product are shown in Table 1.

Abstract

The invention discloses a method for preparing a colored cementitious material, which is needed by the paving construction of a colored concrete road surface. A double-screw extruder or a single screw extruder is utilized, various raw materials of the colored cementitious material are added to the feed inlet of the extruder, sheared and mixed through the screw in the extruder and extruded to finally obtain a colored cementitious material product. The invention has the advantages of continuous production, short making cycle, high production efficiency, few needed production facility, less occupying area, less equipment investment and low production and operation cost.

Description

technical field [0001] The invention relates to a method for coloring cement. Background technique [0002] Colored cement is a kind of special-purpose building material, mainly used in the construction field that requires color warning or landscaping. [0003] Color binders generally include organic polymer materials, organic solvents and inorganic mineral materials, and polymer materials generally include resins, styrene-butadiene-styrene triblock copolymers (SBS), styrene-butadiene rubber (SBR), etc. Organic solvents generally include lubricating oil base oil, lubricating oil solvent refined extraction oil, etc. Inorganic mineral materials generally include iron oxide, chromium oxide, titanium oxide, cobalt oxide, etc. [0004] Due to the use of a variety of raw materials that are immiscible under normal conditions in the color cement, in order to improve the mutual dispersion and interaction between the various materials, the existing production method of the color ceme...
