With the continuous innovation and progress of silica gel industry technology, the application of silicone rubber products in life is also more and more wide, but sometimes in the application will encounter some problems, such as how to silicone rubber products can bond with metal, the following Outford to share with you the realization of silicone rubber products and metal bonding 4 steps process:

A, Metal surface treatment, to achieve adhesion, first of all to the metal surface processing, the commonly used method is: chemical, mechanical, and three kinds of solvent, silicone products factory is chosen according to the actual method commonly, sandblasting machine processing method often USES, use sand cloth or emery wheel grinding, especially sand blasting method, low cost, fast speed, the effect is good, for a wide range of applications. Chemical treatment is also more commonly used, especially the anodization of aluminum and its alloys, and the copper plating of steel. After treatment of the metal surface, the surface of the treatment should be timely coated with adhesive, affixed with silicone rubber products or immersed in inert solvent.

Second, the design of metal joints (recommended products: fluorine rubber products joints), in order to achieve the adhesion of silicone rubber products and metal, the second is to start from the adhesion of joints, because the overall design of the product is part of the first understanding of the design principle of joints:

1) Try to increase the bonding area and improve the bearing capacity of the bonding joint;

2) The force mode of the adhesive joint should be shear force or tensile force to prevent peeling force;

3) The bonding length in the force direction should not be too long, and the bonding width should be increased as much as possible;

4) The force direction of lamination adhesion should avoid separation between layers;

5) Beveled bonding is better than right Angle bonding;

6) The joint with transverse force should be bonded by die surface. According to the above principles and the characteristics of rubber products, it is generally adopted to drill holes in metal parts and grooves in threads to improve the bonding strength of joints.

Three, the construction of adhesives

Surface treatment of qualified metal parts, the adhesive surface can be applied by brushing, spraying, rolling coating, knife scraping, dipping and other methods. Which method can be used according to the size of the parts and the characteristics of the adhesive to decide.

Four, adhesive and vulcanization, hot paste and cold paste two methods, adhesive can be used for mechanical or pressing compaction. Film should not be too thick, thin film layer by layer to the required thickness of the method. Generally, the thickness of hard film is 0.1 to 1.5 mm, and the thickness of soft film is not more than 4 to 5mm, so as not to contain bubbles in the film. Vulcanization bonding can be divided into hot vulcanization and cold vulcanization. Hot vulcanization bonding is to stick the metal parts of the film under a certain pressure and temperature, so that the adhesive material and metal complete bonding. Cold vulcanization bonding is the use of adhesives at room temperature, through a certain time of pressure to allow natural vulcanization, so that the vulcanization glue and metal bonding. Pressure is an indispensable condition of bonding process, pressure and temperature, depending on the product and its formula.

Above all, to implement a silicone rubber products and metal bonding, according to the four steps, the metal surface, joint, adhesive, bonding method, but the silicone products factory in implementation should pay attention to the following points, such as metal surfaces treated by chemical method if not handled in time will be affected by dust, such as greenhouse gas pollution and oxidation rust, and, The construction of the binder requires uniform consistency and a certain amount of glue, sizing the environment temperature should be controlled in 15~35℃, relative humidity below 70%, so that the solvent volatilization and avoid surface dew.
