What is the development of plus molding liquid silica gel?
Adding molding liquid silica gel (LSR) is a new type of silica gel which USES excessive metal complex (platinum, nickel, rhodium, etc.) as catalyst to form a bridge between si-h and si-ch =CH2 to obtain silicone rubber elastomer.
What is it like to add molding silicone products?
In the early 1970s, foreign countries began to study the injection molding process of liquid silicone rubber.
However, due to the immature technology in all aspects, it can only be suitable for extrusion molding process.
In the 1980s, the development of liquid silica gel was slow, and several technical problems were difficult to solve.
Second, how to ensure that there is enough operation time after no material mixing without crosslinking;
The third is the limitation of mold design level.
1990s, is the era of great development of liquid silica gel, first, a large number of use of MQ silica gel to solve the contradiction between the fluidity and strength of silicone rubber;
Secondly, the technology of cross-linking inhibitor has been continuously improved. From the simple use of alkyne alcohol compounds to the use of alkyne alcohol and sih-containing polysiloxane addition products, platinum microcapsule technology has also made great progress.
Third, die design of the cold flow module technology for liquid silica gel in the process on the road.
After 90's, the variety of silica gel began to diversify, at present almost all the varieties of high temperature silica gel, liquid silicone rubber, and its performance is better than room temperature vulcanized silica gel.
This widens the space for the application of liquid silica gel.
Liquid silica gel most need to be combined with other materials to the ultimate performance!
More widely used, such as glass, nylon, metal, PET, PC, PPSU and so on.
The surface of the material was treated with flame or corona (some materials were required), and then coated with Primer, and then compounded with vulcanization by injecting liquid silica gel and bonded material.
This was followed by an increase in the demand for liquid silicone rubber glue.
