Abstract
The invention discloses a high-efficiency acid-free pretreatment process of a tire bead steel wire, which comprises the steps of polishing and degreasing a tai-acid steel wire, treating the tai-acid steel wire by using a surface treating agent, and treating the tai-acid steel wire by using a treating fluid to reduce the pollution of the treatment process to the environment.
Description
Technical Field
The invention relates to the technical field of tire preparation, in particular to a high-efficiency acid-free pretreatment process for a tire bead steel wire.
Background
With the development of light weight and high speed of automobiles, radial tires, which are important components of automobiles, are rapidly applied and developed with the advantages of high speed, energy saving, light weight, long driving range, and the like. The radial tire bears the acting forces of tension, compression, torsion, centrifugation and the like in the use process, and the quality of a tire bead steel wire serving as one of framework materials directly influences the quality of the tire. The currently used bead wire is a tin-plated bronze wire used to reinforce the rim of a tire. The tyre bead is a steel wire ring which is weaved by tyre bead steel wires and isolation rubber, and the outer tyre is tightly and stably fixed on the tyre bead. When an automobile runs, the tire bead and the tire bead edge are stressed greatly, if a tire bead steel wire of a framework material forming the tire bead is corroded, the strength is insufficient, the tire bead is easy to loosen, the tire is burst, and safety accidents occur, so that steel wire manufacturers and tire enterprises pay attention to the problems.
Disclosure of Invention
The invention aims to provide an efficient acid-free pretreatment process for a tire bead wire, which solves the problem that an acidic substance is required to be used in the existing tire bead wire treatment process to pollute the environment.
The purpose of the invention can be realized by the following technical scheme:
an efficient acid-free pretreatment process for a tire bead wire specifically comprises the following steps:
step S1: grinding the tire bead steel wire by using No. 300 abrasive paper, and then grinding by using No. 1000 abrasive paper to obtain a polished steel wire;
step S2: soaking the polished steel wire in a degreasing agent for 50-60s at the temperature of 30-40 ℃ to obtain a degreased steel wire;
and step S3: soaking the degreased steel wire in a surface treating agent for 1-2h at 50-60 ℃, taking out the steel wire until no liquid drops drop, and preserving heat for 1-2h at 110-120 ℃ to obtain a pretreated steel wire;
and step S4: soaking the pretreated steel wire in the treatment fluid, adding a sodium hydroxide solution until the pH value is 10-11, carrying out ultrasonic treatment for 20-30min under the conditions that the frequency is 30-50kHz and the temperature is 40-50 ℃, taking out the steel wire and drying to obtain the tire bead steel wire.
Further, the degreasing agent in the step S2 is prepared from the following components: 5-8g/L of sodium carbonate, 5-8g/L of sodium metasilicate pentahydrate, 4-6g/L of sodium gluconate, 5-8g/L of 4A zeolite, 1-3g/L of sodium nitrite and 4-6g/L of lauryl alcohol polyoxyethylene ether, and the solvent is water.
Further, the mass fraction of the sodium hydroxide solution in step S4 is 150%.
Further, the surface treating agent is prepared by the following steps:
step A1: dissolving 2, 2-dimethylolpropionic acid in deionized water, adding sodium hydroxide, stirring for 10-15min at the rotation speed of 300-500r/min and the temperature of 30-40 ℃, adding epoxy chloropropane, reacting for 3-5h, adjusting the pH value of the reaction solution to 6-6.5 to prepare an intermediate 1, uniformly mixing the intermediate 1, 2-thiophenemethylamine and methanol, carrying out reflux reaction for 10-15h at the temperature of 65-70 ℃, and distilling to remove the methanol to prepare an intermediate 2;
the reaction process is as follows:
step A2: uniformly mixing the intermediate 2, 2-aminobenzimidazole, 1-hydroxybenzotriazole and tetrahydrofuran, reacting for 6-8h at the rotation speed of 200-300r/min and the temperature of 40-50 ℃ to obtain an intermediate 3, uniformly mixing the intermediate 3, acrylic acid, p-toluenesulfonic acid and DMF, and reacting for 8-10h at the rotation speed of 150-200r/min and the temperature of 120-130 ℃ to obtain an intermediate 4;
