An experimental mold for performance testing of silicone rubber

Abstract

The invention discloses an experimental mold for performance testing of silicone glue, which relates to the technical field of silicone glue. The invention includes a base, a lower mold base and an upper mold base, the upper surface of the base is fixedly connected with the lower surface of the lower mold base, and the lower mold base and the upper mold base are slidingly fitted; the present invention uses a movable mold, a fixed mold and a heating coil, The movable mold can be clamped with different experimental models, and then the lower surface of the experimental model and the upper surface of the fixed mold can be coated with silicone glue, and finally the upper mold base and the lower mold base can be slid up and down or left and right to test the silicone. The strength of the glue under the action of longitudinal tension and transverse shear force. At the same time, the silicone glue can be heated by the heating coil to test its strength at different temperatures. In addition, because the movable mold can fix experimental models of different sizes, Different experimental models have different contact areas with the stent, so this device can also be used to test the influence of different contact areas of silicone glue on the strength of silicone glue.

Description

Technical field[0001]The present invention belongs to the technical field of silicone rubber test, and more particularly to a silicone adhesive performance test experimental die.Background technique[0002]Silicone gel is a similar ointment, and once the moisture in contact with the air is solidified into a tough rubber solid material. It is mainly divided into denatocetic acid type, desisted type, de-ammonia, and delta. Silicone rubber is commonly known as glass glue because it is often used for bonding and sealing of glass. One component silicone glass glue is a similar ointment, once the moisture in the air is solidified into a tough rubber solid material. During the production of silicone gum, in order to detect the performance of silicone rubber, its strength is often required to be tested.[0003]However, existing silicone gels are generally only testing the effect of tensile, shear, or temperature in a set of molds during performance test, and the test efficiency is low, and a mo...

Problems solved by technology

[0004] The object of the present invention is to provide an experimental mold for performance testing of silicone rubber, which solves the problem that in the performance testing of existing silicone rubber, only one influencing factor of tensile force, shear force or temperature can be tested in a set of molds. , the test efficiency is low, and a set of molds is only suitable for testing a set of experimental models, which is inconvenient for comparative testing
