Problems solved by technology

[0006] Although the above technologies can solve certain problems and improve the drum in terms of anti-corrosion, anti-rust, wear resistance, impact resistance, aging resistance, and tear resistance, these technologies still have not solved the problem of the drum being exposed to acid and alkali for a long time. Chemicals are also involved in the use of high temperature and low temperature environments

[0033] like figure 1 As shown, using the above-mentioned rubber coating layer material to prepare the roller rubber coating layer includes the following steps:

[0034] A. When using styrene-butadiene rubber as the main material to prepare the rubber compound for the acid and alkali-resistant rubber coating layer of the roller, firstly pretreat the material, and then plasticize the styrene-butadiene rubber on the open mill at 16 o'clock, and the roller temperature is 20-40 °C , Roll distance 1mm, thin pass method, af...

Abstract

The invention discloses a rubber cladding layer for cylinder and preparation method thereof, wherein the outer side of the roller core of the cylinder is covered with a rubber cladding layer; the rubber cladding layer comprises the following components based on parts by weight: 100 parts of styrene butadiene rubber, 3-5 parts of vulcanizer, 0.45-1.5 parts of accelerator, 6-10 parts of activator, 30-70 parts of reinforcing agent, 10-30 parts of plasticized softener, 3-5 parts of antiager and 20-40 parts of special compounding ingredient. The preparation method comprises preparation of rubber, processing on the roller core, shaping and vulcanizing. In comparison with the existing technology, the acid-base proof rubber cladding layer is prepared by new formula materials and can keep the original physical performance after a long time stay in the acid-base bath lotion such that the cylinder of a conveyor can be used in acid-base and chemicals environment for a long time.

Description

technical field [0001] The invention relates to the technical field of conveyors, in particular to a rubber coating layer of a roller and a preparation method thereof. Background technique [0002] The rubber coating layer of the existing ordinary rollers cannot work in chemicals such as acid, alkali, and salt solution. When the rubber coating layer of ordinary rollers is in contact with acid, alkali, and salt solution, it will cause corrosion, cause rubber swelling, and produce rubber molecules. Fracture, depolymerization, and decomposition and dissolution of compounding agents lead to a significant decrease in its mechanical strength and physical properties, and the rubber layer gradually becomes sticky, oxidized, hardened, embrittled, cracked, etc., and cracks occur due to the attack of ozone. So that the corrosion completely loses the ability to work. [0003] With the continuous development of industrial production, the use of rollers is required to be more and more wi...
