Synthetic example 1

[0024] Put allyl methacrylate and acrylic acid into the reaction kettle according to the molar ratio of 1-10, start stirring, and control the stirring speed at 20-100 rpm, and start to heat up to 60-100°C after adding the platinum catalyst. Then add hydrogen-containing silicone oil evenly and continuously within 60 minutes (the amount of hydrogen-containing silicone oil is 33% of the total mass number of allyl methacrylate and acrylic acid), maintain the reaction temperature between 60 and 100 °C, and keep warm for 0.5 ~10 hours. Then, turn off the stirring, cool to below 50°C and then open the discharge valve to discharge. The polymer co-modified by allyl methacrylate and acrylic acid group (hereinafter referred to as polymer 1) can be obtained

Synthetic example 2

[0026] Put allyl acrylate and acrylic acid into the reaction kettle according to the molar ratio of 1-10, start stirring, control the stirring speed at 20-100 rpm, add the platinum catalyst and start to heat up to 60-100°C, and then Add hydrogen-containing silicone oil evenly and continuously within 60 minutes (the amount of hydrogen-containing silicone oil is 38% of the total mass number of allyl methacrylate and acrylic acid), keep the reaction temperature between 60 and 100°C, and keep warm for 0.5-10 Hour. Then, turn off the stirring, cool to below 50°C and then open the discharge valve to discharge. The polymer co-modified by allyl acrylate and acrylic acid group (hereinafter referred to as polymer 2) can be obtained

Synthetic example 3

[0028] Put allyl methacrylate and acrylic acid into the reaction kettle according to the molar ratio of 1-10, start stirring, and control the stirring speed at 20-100 rpm, and start to heat up to 60-100°C after adding the platinum catalyst. Then add hydrogen-containing silicone resin evenly and continuously within 60 minutes (the amount of hydrogen-containing silicone resin is 60% of the total mass number of allyl methacrylate and acrylic acid), maintain the reaction temperature between 60 and 100 °C, and continuously Keep warm for 0.5-10 hours. Then, turn off the stirring, cool to below 50°C and then open the discharge valve to discharge. The silicone resin co-modified by allyl methacrylate and acrylic acid group can be obtained (hereinafter referred to as resin 1)

Abstract

The invention relates to an optical transparent adhesive, and particularly relates to modified organic silicon material-based UV glue for processing laminated glass and application thereof. The UV glue disclosed by the invention comprises the following components by mass percent: (A) 20-80% of organosilicon polymer co-modified by allyl (meth)acrylate and acrylic acid, (B) 20-80% of organosilicon resin co-modified by allyl (meth)acrylate and acrylic acid, (C) 0-50% of (meth)acrylic ester active monomer, and (D) 0.5-3% of photoinitiator. The modified organic silicon material-based UV glue can be applied to processing of the laminated glass of a display, a touch screen and an optical device, and has the advantages of being quick to solidify, low in shrinkage rate, good in flexibility and good in adhesion, and applicable to mechanical processing of cutting, grinding and the like; meanwhile, the glue is not resistant to poaching, and easy to fall off in a large area, and the residual glue on the bonding surface is easy to self-emulsify and dissolve. Therefore, no residual glue exists.

Description

technical field [0001] The invention relates to polymer materials, in particular to a UV glue for glass lamination processing based on modified organic silicon materials and its application. Background technique [0002] At present, tablet computers and touch-screen mobile phones are becoming more and more popular. With the development of these electronic portable terminal products in the direction of light weight and thinning, the glass used in capacitive touch screens is also light and thin. The thickness of the glass sensor substrate is as thin as 0.33mm. The processing efficiency of this light and thin glass is relatively low, and at the same time, the damage rate in the cutting process is also high, which is a waste of manpower and material resources. Glass lamination processing UV glue, also known as glass processing temporary protection UV glue or water-soluble UV glue, is based on modified acrylic resin, contains methacrylic acid and its ester monomers, and is a phot...
