Abstract

The invention relates to the technical field of polymer nano organic silicon materials, in particular to an integrated black silica gel OCR with performance improved based on crosslinking density and a preparation method of the integrated black silica gel OCR. The integrated black silica gel OCR is prepared by mixing a component A and a component B in proportion, wherein the component A is prepared from the following raw materials of divinyl polydimethylsiloxane and a platinum catalyst, and the component B is prepared from the following raw materials of divinyl polydimethylsiloxane, a cross-linking agent, an accelerant and a coloring agent. According to thepreparation method of the integrated black silica gel OCR, a cross-linking agent is added into an OCR liquid silica gel bonded by traditional glue, the cross-linking agent is hydrogen-containing silicone oil, is reactive silicone oil containing SiH bonds, can play a role in adjusting the understanding cross-linking density, increases the cross-linking density of silica gel, and enables the mechanical strength of the silica gel to be better; and through cooperation of acetenyl cyclohexanol and a platinum catalyst, a curing reaction can be prompted, and the curing reaction speed is adjusted.

Description

technical field [0001] The invention relates to the technical field of polymer nano-organosilicon materials, in particular to an integrated black silica gel OCR whose performance is improved based on crosslinking density and a preparation method thereof. Background technique [0002] With the acceleration of the development of automobile intelligence, vehicle-mounted displays are developing towards large-size, multi-screen, high-definition, interactive, and multi-modal. There are also higher requirements for display performance, including high contrast, low reflectivity, wide Viewing angle, high brightness, touch control and fast response, etc. In addition, the novel design of the details and structure of the vehicle display screen can also play an unexpected role in improving product competitiveness. Therefore, the all-in-one black technology that can create novel, eye-catching, beautiful and technological vehicle display effects will become one of the trends; [0003] Th...
