Embodiment 1

[0069] Embodiment 1, the preparation of organosilane coated steel wire compound

[0070] Add 100 g of TESPT into a 20 x 10 x 8 cm glass tank. After dissolving 5g DPG with 50g ethanol solution, add it into the glass tank containing TESPT. Put the glass tank on the SHA-DA digital display high-temperature oil bath oscillator, and vibrate back and forth at 100°C for 30 minutes to mix TESPT and the ethanol solution containing DPG evenly. Put in a steel wire about 15cm long, cover with a lid, and react with reciprocating vibration at 100°C for 30min. Take out the steel wire with tweezers, wash the steel wire three times with ethanol, and wash off the unreacted silane coupling agent. After drying in an oven at 100° C. for 30 minutes, a steel wire composite coated with organosilane can be obtained. Among them, the oscillation amplitude is 20mm, and the rotation speed is 200r / min.

Abstract

The invention relates to a steel wire compound coated with organosilane for rubber, a preparation method and a coating method. The complex includes 100 parts of a silane coupling agent and 10 to 100 parts of a solvent, wherein the silane coupling agent is a silane coupling agent containing sulfur or an unsaturated double bond, and the compound may also include catalysts 1 to 100 parts. 20 servings. The structural feature of this compound is that the organosilane coupling agent reacts with the hydroxyl group on the metal surface to form a covalent bond through the reaction of the alkoxy group on the silicon, and at the same time, the sulfur or double bond in the organosilane coupling agent participates in rubber vulcanization, and the rubber molecule Forming covalent bonds, it can be used as a skeleton material in the field of rubber to increase the interface bonding force between steel wire and rubber, and also has the function of steel wire anti-corrosion.

Description

technical field [0001] The invention relates to the field of rubber, in particular to an organosilane-coated steel wire composite for rubber, a preparation method and a coating method. The organosilane-coated steel wire composite can be used as a skeleton material to increase the bond between steel wire and rubber interface bonding. Background technique [0002] The main methods of metal surface treatment include traditional treatment methods such as sandblasting, sandpaper grinding, pickling, phosphating, chemical etching, and chemical conversion transition layer, as well as emerging treatments such as rare earth passivation, dacromet, and silane coupling agents. method. (Wang Xueming, Application research of silane coupling agent in metal pretreatment and organic coating [D], Shandong University, 2005) [0003] Silane coupling agent (abbreviated as "SCA" or "silane") was first developed in the 1940s by United Compound Company and Dow Corning Corporation in the United Sta...
