Abstract

The invention relates to a method for bonding a rubber plate by using a chloroprene rubber adhesive, which comprises the following steps: step 1, preparing a panel to be bonded, determining a first adhesive region on the panel, and forming a hole in the panel, the hole being located in the first adhesive region; 2, a rubber plate is prepared, a second adhesive area is determined on the rubber plate, and the second adhesive area can completely cover the first adhesive area and has a remaining area; step 3, brushing a first chloroprene rubber adhesive in the second adhesive area, and placing the second adhesive area with the second adhesive area facing upwards for at least 18 hours; and step 4, brushing a second chloroprene rubber adhesive in the first adhesive area, correspondingly adhering the rubber plate obtained in the step 3 to the first adhesive area, and pressing to complete the adhesion of the rubber plate. The high dimensional precision of the bonded rubber plate is ensured, the sealing performance is good, the dislocation of the drilling position is avoided, and the bonding quality is effectively improved.

Description

technical field [0001] The invention relates to the technical field of bonding methods for rubber sheets, in particular to a method for bonding rubber sheets using a neoprene adhesive. Background technique [0002] Neoprene adhesive is made of chloroprene rubber (CR) as the base material, adding additives such as resin and solvent, because it has good initial adhesion, strong impact resistance and medium resistance, and the construction process is simple and easy to manufacture. Low cost, widely used in aviation manufacturing, construction, home improvement and other industries. [0003] When using neoprene adhesive to stick shoes, tires, etc., directly apply the neoprene adhesive to the two sides to be bonded, and then press and bond. There is no high requirement for bonding dimensional accuracy and airtightness. Rubber sheet bonding technology is a technology that uses adhesives to connect a rubber sheet to another material to form a continuous, firm, and stable overall s...
