Definitions
- the present invention relates to the coating of supports with silicone, for the production of walls of inflatable safety bags, and it relates more particularly to the manufacture on the site of coating of the silicone used to carry out this coating.
- the silicone to be used arrives at the coating site in the almost final state, in the form of two components (a base and a catalyst) which are simply mixed on site at the time of coating.
- This known method has the disadvantage that it is not possible to adjust the basic components of the silicone, and therefore the final formula thereof, according to the desired performance of the inflatable safety bag to be made (mechanical strength, thermal properties) and according to the coating supports used (thick support, thin support).
- the object of the present invention is to remedy the above-mentioned drawbacks presented by the known method of coating and to this end it proposes a new method of coating a support, for example textile, with silicone, for the production of inflatable safety bags, which while being more economical, makes it possible to use for coating a silicone adapted to the type of support used and to the specifics of the inflatable safety bag to be made.
- the method of coating a silicone on a support intended for making inflatable safety bags comprises the continuous production, on the coating site and on a single and same production line, of the following operations: - pumping and dosing of at least three components of the silicone, mixing of said at least three components to obtain the silicone to be coated, coating of said silicone thus obtained on said support.
- the mixing of said at least three components of the silicone can be carried out in several successive operations.
- the production of the silicone on the coating site by mixing the various basic components thereof makes it possible to choose the nature of the components to be used, as well as the necessary quantities of each of them according to the particular application to be carried out, both at the level of the coated support to be obtained and of the inflatable safety bag to be produced.
- This process according to the invention also makes it possible to significantly reduce the cost price of the coating silicone compared to the current process where the two components are obtained in the final state.
- the method is applicable to any suitable coating support, whether textile or not.
- component A can be a mixture based on polymethylvinyl and polymethylhydrogenosiloxane
- components B and C can each be alpha, omega-divinylpolydimethylhydrogenosiloxane.
- this second mixture M2 is then mixed with a dye E, for example a pigment, chosen as a function of the inflatable safety bag to be made, in order to obtain the final mixture MF constituting the coating silicone.
- a dye E for example a pigment, chosen as a function of the inflatable safety bag to be made
- the coating operation is then carried out continuously (not shown) on the textile support with the silicone thus obtained.
