Rubber and metal adhesives

Right!

Rubber and metal adhesive refers to a kind of adhesive glue for rubber and metal produced by Polycom.

With the rapid development of the rubber industry, rubber composite materials have been widely used, and the quality of rubber and metal adhesives is the key to the success of composite materials. The increase in the variety of composite products and the expansion of application fields has increased the requirements for bonding technology. harsh. The traditional technologies such as chlorinated rubber method and isocyanate method cannot meet the new requirements. The United States LORD company specially developed a rubber-to-metal adhesive in 1956, which can be used for rubber-to-metal bonding, rubber-to-plastic, and fiber fabric bonding. Subsequently, the national industrial polyton also successively developed and produced national adhesives that were comparable to foreign products.

Surface treatment: degreasing after mechanical treatment (sandblasting), or chemical treatment to remove processing oil, rust or other oxide layers. Use steel sand (bead) to spray ordinary steel, cast iron and other ferromagnetic metals. The surface storage time after surface treatment should be controlled before oxidation and rust appear again; use quartz sand to spray stainless steel, aluminum, brass, zinc and other non-ferromagnetic metals , And the glue must be completed within 90 minutes after surface treatment.
Stirring: Stir thoroughly before use to achieve uniform mixing before use.
Gluing method: dipping method, spraying method, brush coating method, roller coating method, transfer method.
Drying: It should be dried in clean air for about 30 to 45 minutes (room temperature) after the application of glue. Using a 65-82C air-blast oven is helpful for faster and thorough drying of the glued parts.
Parking: If the rubberized parts are properly stored, they can be isolated from dust, oil and water vapor, and can be parked for up to one month.
Vulcanization: After the rubber-coated parts are placed in the hot mold, the rubber should be filled quickly and the mold closed to prevent the pre-curing of the adhesive from failing, so as to ensure that the adhesive and rubber are vulcanized at the same time and obtain the best bonding performance.
Vulcanization time: It depends on the rubber vulcanization time.
