Embodiment 1
[0030] An improved resin for 3D printing photosensitive adhesive, calculated by parts by weight, its raw material composition and content are as follows:
[0031]
[0032] The polymerization inhibitor is a mixture of 2-tert-butyl hydroquinone and 2,5-di-tert-butyl hydroquinone in a mass ratio of 1:1; the catalyst is isopropyl chloride of chloroplatinic acid Alcoholic solution.
[0033] The above-mentioned preparation method of an improved 3D printing photosensitive adhesive resin specifically includes the following steps:
[0034] Add 10g of methyl hydrogen-containing silicone oil and 10g of dipentaerythritol hexaacrylate into a 500ml three-neck flask, then add 0.01g of hydroquinone, pass in protective gas, stir and heat, raise the temperature to 60°C, and add 0.01g of platinum chloride For the acid complex, keep the temperature constant for 3 hours under stirring, stop heating, wait until the temperature of the flask drops to room temperature, and obtain the resin for UV ...
Embodiment 2
[0039] An improved resin for 3D printing photosensitive adhesive, calculated by parts by weight, its raw material composition and content are as follows:
[0040]
[0041] The polymerization inhibitor is a mixture of hydroquinone and p-hydroxyanisole in a mass ratio of 1:2; the catalyst is a tetrahydrofuran solution of chloroplatinic acid.
[0042] The above-mentioned preparation method of an improved 3D printing photosensitive adhesive resin specifically includes the following steps:
[0043] Add 10g of methyl hydrogen-containing silicone oil and 10g of dipentaerythritol hexaacrylate into a 500ml three-neck flask, then add 0.01g of hydroquinone, pass in protective gas, stir and heat, raise the temperature to 60°C, and add 0.01g of platinum chloride For the acid complex, keep the temperature constant for 3 hours under stirring, stop heating, wait until the temperature of the flask drops to room temperature, and obtain the resin for UV curing LED encapsulation glue.
