Problems solved by technology

[0004] At present, the OCA materials used for lamination on the market are mainly acrylic materials. Due to the fact that this material is prone to bubbles during lamination, the cost is high and the thickness is difficult to reduce , and problems such as low light transmittance, poor weather resistance, easy yellowing and insufficient flexibility

Synthetic example 1

[0027] Put allyl methacrylate and vinyl triethoxysilane into the reaction kettle according to the molar ratio of 1-10, start stirring, control the stirring speed at 20-1000 rpm, and start to heat up to 90 after adding the platinum catalyst ~100 o C, then add the mixture of hydrogen-containing silicone oil and hydrogen-containing silicone resin uniformly and continuously within 60 minutes, and maintain the reaction temperature at 90-100 o Between C, keep warm for 0.5 to 10 hours. Then, turn off stirring and cool to 50 o Below C, the discharge valve can be opened to discharge the material. The polymer and silicone resin in which allyl methacrylate and vinyltriethoxysilane are grafted or terminated together can be obtained. (hereinafter referred to as resin 1)

Synthetic example 2

[0029] First add allyl methacrylate and vinyl trimethoxysilane into the reactor according to the molar ratio of 1 to 10, start stirring, and control the stirring speed at 20 to 1000 rpm. After adding the platinum catalyst, start to heat up to 90 ~100 o C, then add the mixture of hydrogen-containing silicone oil and hydrogen-containing silicone resin evenly and continuously within 60 minutes (how much?), and maintain the reaction temperature at 90-100 o Between C, keep warm for 0.5 to 10 hours. Then, turn off stirring and cool to 50 o Below C, the discharge valve can be opened to discharge the material. The polymer and silicone resin in which allyl methacrylate and vinyltrimethoxysilane are grafted or terminated together can be obtained. (hereinafter referred to as resin 2)

Synthetic example 3

[0031] First add allyl acrylate and vinyl trimethoxysilane into the reaction kettle according to the molar ratio of 1-10, start stirring, control the stirring speed at 20-1000 rpm, and start to heat up to 90-100 rpm after adding the platinum catalyst. o C, then add the mixture of hydrogen-containing silicone oil and hydrogen-containing silicone resin evenly and continuously within 60 minutes (how much?), and maintain the reaction temperature at 90-100 o Between C, keep warm for 0.5 to 10 hours. Then, turn off stirring and cool to 50 o Below C, the discharge valve can be opened to discharge the material. A polymer and a silicone resin in which allyl acrylate and vinyl trimethoxy are grafted or terminated together can be obtained. (hereinafter referred to as resin 3)

Abstract

The invention relates to an optical transparent adhesive, and particularly relates to modified organosilicon material-based dual-curing optical glue. The dual-curing optical glue disclosed by the invention comprises the following components by mass percent: (A) 47-97% of organosilicon polymer and silicon resin grafted or blocked by (methyl) acrylic acid allyl ester and vinylsilane, (B) 0-50% of (methyl) acrylic ester active monomer, (C) 0.5-3% of photoinitiator, and (D) 0-0.5% of metallo-organic compound catalyst. The dual-curing optical glue can be applied to a display screen, a touch screen and an optical device, and has the advantages of high light transmissivity, ultraviolet resistance, ageing resistance, high temperature resistance, good low-temperature flexibility, low cure shrinkage rate, self-leveling foam discharging property, good hydrophobic properties, strong binding power on glass, small fitting thickness and the like.

Description

technical field [0001] The invention relates to polymer materials, in particular to a dual-curing optical glue based on modified organic silicon materials and its application. Background technique [0002] With the advent of the smart mobile era, tablet PCs and touch-screen mobile phones have become increasingly popular. In the past, the limitation of mobile phones was the communication function. However, the performance of smart devices including smartphones and tablet PCs is close to that of notebooks. The convenience of performing and enjoying high-level business and entertainment activities all the time. For this reason, people have higher and higher requirements on the visual effect of the display panel. [0003] The trend of filling the air layer between the touch screen and the display panel (LCD, OLED) to improve visibility is in many ways a very logical development. OCA (Optically Clear Adhesive) is an optically transparent adhesive. Using OCA to fill the air laye...
