preparation example Construction

[0025] The preparation method of the above-mentioned photothermal dual-curing black light-shielding resin composition comprises the following steps: (a) mixing the alicyclic epoxy resin and the defoamer of the formulation amount, and then adding the SiO2 of the formulation amount 2 Powder and carbon black are mixed by ball milling to obtain the first masterbatch; (b) mixing the alicyclic epoxy resin, organosilicon modified epoxy resin, photoinitiator, thermal initiator and stabilizer of the formulation amount, and then Add epoxy toughener and defoamer and mix to obtain a second masterbatch; (c) mix the first masterbatch, the second masterbatch and defoamer in proportion, defoam and refrigerate for future use. Divide each component into the first masterbatch and the second masterbatch, etc. for separate batching, which is conducive to the full mixing of each material, and is conducive to the full mixing of each component to produce a synergistic effect: when the viscosity of the...

Embodiment 1

[0028] This embodiment provides a photothermal dual-curing black light-shielding resin composition and a preparation method thereof. The specific steps are as follows (clean the ball-milling jar and the ball-milling beads with ethanol before preparation, and wipe the ball-milling jar with a clean dry rag after draining the cleaning solution. and ball-milled beads, put in an oven at 80°C to remove residual ethanol):

[0029] (a) Configuration of the first masterbatch: Weigh 58.2g of cycloaliphatic epoxy resin 2021P and defoamer KSZ-660.005g for three-dimensional mixing (2000rmp, 200s, 2-3 times); add SiO 2 Powder (TSP-H10) 90g, carbon black #252.7g, after mixing evenly, transfer to a ball mill tank for ball mill mixing, the speed is 200rmp / min, turn for 4h, and set aside;

[0030] (b) Configuration of the second masterbatch: Weigh 74g of cycloaliphatic epoxy resin 2021P and 6.7g of silicone modified epoxy resin (JP-H26), stir and mix, then add photoinitiator (R-GEN 261 ) 2.3g,...

Embodiment 2

[0033] This embodiment provides a photothermal dual curing black light-shielding resin composition, the preparation method of which is basically the same as that in Example 1, the difference is: in step (c), the first masterbatch, the second masterbatch and the defoaming The mass ratio of the agent is 100:10:0.01.

Abstract

The invention relates to a photothermal dual-curing black light-shielding resin composition and a preparation method thereof, which is formed by mixing a first masterbatch, a second masterbatch and a defoamer at a mass ratio of 100:10-30:0.01-0.03, The first masterbatch includes the following components in parts by weight: 50-60 parts of alicyclic epoxy resin; 0.001-0.01 part of defoamer; SiO 2 80-100 parts of powder; 2-5 parts of carbon black; the second masterbatch includes the following components in parts by weight: 70-100 parts of alicyclic epoxy resin; 5-10 parts of silicone modified epoxy resin 1-5 parts of photoinitiator; 1-5 parts of thermal initiator; 0.5-1.5 parts of stabilizer; 10-20 parts of epoxy toughener; 0.001-0.01 part of defoamer. In this way, the resin composition can still ensure the full dispersion of carbon black and is not easy to settle when the viscosity is low, the volume shrinkage rate is low, and the light curing can ensure the initial adhesion and pre-crosslinking degree. The relay is strong.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a resin composition, in particular to a photothermal dual-curing black light-shielding resin composition and a preparation method thereof. Background technique [0002] The middle base material of lens shading sheet is PET material, and the upper and lower sides are coated with carbon resin. The carbon-containing resin coating is the light-shielding glue, which is a black polymer material with light-shielding function. Its main function is to fix the light-shielding film and other lens components, which requires the light-shielding glue to be halogen-free, corrosion-free and highly bonded. force performance. [0003] The cohesive force of the glue is caused by the molecular contact and interfacial force between the two materials. The process of continuous contact between the adhesive and the adherend is called wetting. To make the adhesive wet the solid surface, the surface tensio...
