Embodiment 1
[0049] A preparation method of UV curing grid exhaust glue, comprising the steps of:
[0050] (1) The raw materials of the adhesive layer: styrene block copolymer modified by vinyl grafting, tackifying resin, aging agent, free radical photoinitiator, and expansion ball are dissolved in toluene / heptane with a solid content of 45%. Stir and dissolve in the alkane system, and then let stand to defoam to obtain stretched viscose-reducing glue;
[0051] In terms of parts by mass, the component content of the adhesive layer raw material is: vinyl graft modified styrene-butadiene-styrene block copolymer (U.S. Kraton DX0222, 20% styrene block, 18% diblock content) 50 parts, tackifying resin (39.6 parts Crayville Wingtack Extra, ring and ball softening point temperature 100°C; 5 parts Crayville Wingtack W140, ring and ball softening point temperature 140°C; 2.8 parts of liquid rosin resin (GA-AT) from Arakawa, Japan) 47.4 parts, aging agent (tetrakis [β-(3,5-di-tert-butyl-4-hydroxyphe...
