The vulcanization reaction of two-component room temperature vulcanized silicone rubber is not initiated by water in the air, but initiated by a catalyst. The rubber compound and the catalyst are usually packaged as one component. Curing only begins when the two components are completely mixed together. The curing time of two-component condensation type room temperature vulcanized silicone rubber mainly depends on the type, amount and temperature of the catalyst. The more catalyst used, the faster the sulfidation, and the shorter the standing time. At room temperature, the shelf time is generally a few hours. If you want to extend the shelf time of the rubber, you can use the cooling method. It takes about one day for the two-component condensation type room temperature vulcanized silicone rubber to achieve complete curing at room temperature, but it only takes one hour at 150 ° C. The synergistic effect through the use of accelerators can significantly increase its curing speed. The two-component room temperature vulcanized silicone rubber can maintain elasticity during the synthesis of long silicone fluorine-modified styrene-acrylic emulsion in a temperature range of 65-250 ° C, and has excellent electrical properties and chemical stability. It is resistant to water, ozone, Weathering resistance, simple usage and strong process applicability, therefore, it is widely used as potting and molding materials. Various electronic and electrical components are coated with room temperature vulcanized silicone rubber. After being potted, they can protect against moisture (anti-corrosion, shock, etc.). It can improve performance and stability parameters. The two-component room temperature vulcanized silicone rubber is particularly suitable for deep irrigation. The sealing material has a faster vulcanization time, which is better than the one-component room temperature vulcanized silicone rubber. The two-component room temperature vulcanized silicone rubber has excellent anti-sticking properties after vulcanization, and the shrinkage rate is very small when vulcanized. Therefore, it is suitable for making soft molds, molds for casting epoxy resin, polyester resin, polystyrene, polyurethane, vinyl plastic, paraffin, low-melting alloy, etc. In addition, two-component room temperature vulcanized silicone rubber is used. The high simulation performance can reproduce a variety of exquisite patterns on cultural relics. When using two-component room temperature vulcanized silicone rubber, pay attention to: first weigh the rubber and catalyst separately, and then mix them in proportion. The mixing process should be carefully operated to Minimize the amount of entrained gas. After the rubber mixture is uniform (uniform color), the air bubbles can be removed by standing or decompressing (vacuum degree 700 mm Hg). After it is completely discharged, it is vulcanized into silicone rubber by being left at room temperature or at a predetermined temperature for a certain period of time.
