Embodiment 1
[0031] This embodiment provides an epoxy-based long-lasting fluorescent anti-slip adhesive, including A component and B component, in parts by weight, the A component includes 100 parts of epoxy resin, rare earth silicate-based long-lasting material Sr 2 MgSi 2 o 7 :Eu 2+ , Dy 3+ 5 parts, rare earth aluminate based long afterglow material SrAl 2 o 4 :Eu 2+ , Dy 3+ 10 parts, 60 parts of high permeability silica powder, 40 parts of quartz sand, 8 parts of polyisoprene, 8 parts of SBS, 4 parts of ABS and 5 parts of fumed silica; the B component includes 100 parts of epoxy resin curing agent 3 parts, 3 parts of vinyl silane, 40 parts of high permeability silica powder, 30 parts of quartz sand and 8 parts of fumed silica.
[0032] This embodiment also provides the preparation method of the above-mentioned fluorescent anti-slip glue: put the above-mentioned raw materials of component A into a stirred tank, and stir at a high speed of not less than 1500r / min under a negativ...
experiment example 1
[0050] Take 20 g of the raw material in Comparative Example 1 and place it in a 35mm petri dish, numbered A.
[0051] Take the raw materials in Example 1, and the preparation method is to put the raw materials of component A into a stirred tank, and in a negative pressure state with a vacuum degree of 0.08MPa, stir at a high speed of 1500r / min until uniform, and the stirring time is 20 minutes, and then pass Three-roller machine, the speed ratio of the slow, medium and fast rollers of the three-roller machine is 1:3:9, the speed of the slow roller is controlled at 30r / min, and the roller gap is adjusted to 0.015mm. Put the raw materials of component B into the stirring tank, and stir them at a high speed of 1500r / min under the negative pressure of vacuum degree of 0.08MPa until uniform, and the stirring time is 20 minutes. Mix 10g of component A and 10g of component B and put it in a 35mm Petri dish, numbered B.
