Embodiment 1

[0020] (1) Preparation of hydrogenated castor oil intercalated zeolite powder: the natural zeolite is crushed by a jet mill and passed through a 100-mesh sieve, and calcined at 500-550° C. to constant weight, and naturally cooled to room temperature to obtain calcined zeolite powder; Add 20g of calcined zeolite powder and 5g of hydrogenated castor oil into 100g of water, and stir to form a slurry. The resulting slurry is treated with microwave reflux for 5 minutes using a microwave processor with a microwave frequency of 2450MHz and an output power of 700W. After stirring for 15 minutes, continue the microwave reflux treatment for 5 minutes, and stir After 15 minutes, microwave reflux treatment for 5 minutes again, and repeat until the viscosity of the obtained slurry does not change, and then send the obtained slurry into a spray dryer, and dry the obtained particles into a micropowder through an ultrafine pulverizer to obtain hydrogenated castor oil intercalation Zeolite powd...

Abstract

The invention discloses an ink anti-settling agent for identifying and code spraying before steel pipe delivery, and relates to the technical field of steel pipe identification. A specific preparationmethod comprises the following steps: (1) preparation of hydrogenated castor oil intercalated zeolite powder; (2) preparation of polyglutamic acid grafted acrylic resin; (3) preparation of anti-settling agent. The anti-settling agent disclosed by the invention is used for preparing water-based ink for identifying and code spraying of a steel pipe, and the ink is endowed with excellent storage stability while the safety problem in use of solvent type ink is avoided; moreover, the phenomenon of pigment settling occurring after pigment particles are stored for a long time is prevented, and thusthe normal code spraying and identifying function of the ink is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of steel pipe marking, in particular to an anti-sedimentation agent for ink used for marking and coding of steel pipes before leaving the factory. Background technique: [0002] Steel pipes are not only used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers, it's also a kind of economical steel. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight and save 20-40% of metal, and can realize factory-like and mechanized construction. The use of steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​the protective layer, saving investment and maintenance costs. [0003] Steel pipes need to be coded on the surface or inner wall before leaving the factory, so that customers can intuitively understand the model, type, length, weigh...
