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.
(4) The product is stored under heat preservation and stirring conditions, the storage cost is high, it is not convenient for long-distance transportation, and it is inconvenient to use

Abstract

The invention discloses a method for preparing granular color cementing agent which is used for paving and constructing color concrete pavement. The method uses a double screw extruder or a single screw extruder, and the raw materials of the color cementing agent are added into a feeding port of the extruder and extruded into strips after cutting and mixing by the screw in the extruder, and then the color strips of the color paving cementing agent enters a granulator to be cut into grains after water bath cooling, thus obtaining the granular color cementing agent product. The method can obtain the following effects of: (1) continuous production, short production cycle and high production efficiency; (2) less required production equipment and small occupied area; (3) little equipment investment and low production and running costs; and (4) granular product and convenient storage, transportation and use.

Description

technical field [0001] The present invention relates to a method of colored cement, in particular to a method for producing granular colored cement products. 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...
