Problems solved by technology

[0003] The (1) plastic magnetic "timely stickers" of the prior art are prone to aging, low strength, and non-wearable due to the characteristics of plastics; (2) magnetic rubber cannot meet the requirements of sufficient strength, wear resistance, magnetic force, and oil resistance. Poor performance, poor color solubility, etc.
These products do not meet the characteristics required for marking lines on steel floors
If the magnetic powder is made of ferrite, the existing technology cannot meet various color products. In order to meet the color requirements of the marking line, we have invented this color surface compound vulcanization process and formula material to meet the color marking line products. need

Abstract

The invention belongs to the technical field of high polymer materials, and discloses a high-strength oil-resisting magnetic rubber colorful marker strip and a preparation method of the high-strength oil-resisting magnetic rubber colorful marker strip. The high-strength oil-resisting magnetic rubber colorful marker strip is prepared by vulcanizing and compounding a magnetic layer and a surface layer. According to the high-strength oil-resisting magnetic rubber colorful marker strip and the preparation method, disclosed by the invention, the problems of easiness in aging, low strength and poor wear resistance of plastics in the prior art are solved, and characteristics needed by marker lines on a steel floor are met.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a high-strength oil-resistant magnetic rubber color marking strip and a preparation method thereof. Background technique [0002] The present invention is to solve the expansion of the application extension of the invention "steel floor tile" of this unit. The "steel floor tiles" of the steel floor we provide for industrial and mining enterprises have solved the deficiencies of the original technology of the industrial floor, and improved the strength, wear resistance, impact resistance, dust-free, long service life and other problems of the floor. , Steel floors have now been accepted by the majority of enterprises and have been widely used. However, with the needs of modern civilized production, fixed location management is becoming more and more important, and the role of "marking strips" in custom management is becoming more and more important. Due to the particular...
