Embodiment 1
[0022] The invention discloses a durable rubber sheet for a photovoltaic laminator, comprising the following components in parts by mass:
[0023] 100 parts of rubber matrix, said rubber matrix including hydrogenated nitrile rubber, fluororubber and EPDM rubber with a mass ratio of 6:2:2; through the blending modification of hydrogenated nitrile rubber and fluororubber, further improve the rubber Oil resistance, thermal oxidation resistance and other properties of the matrix; by blending EPDM rubber with hydrogenated nitrile rubber and fluororubber, on the basis of ensuring the excellent corrosion resistance, heat resistance, oxidation resistance and other properties of the rubber matrix, increase The elasticity of the matrix rubber is improved, and the low density of EPDM rubber can be used to add and accommodate a large amount of fillers, thus reducing the cost and improving the mechanical strength, so that the rubber matrix after the blend of the three rubbers has Excellent...
Embodiment 2
[0035] The difference with Example 1 is that the following components by mass are included:
[0036] 100 parts of rubber matrix, said rubber matrix including hydrogenated nitrile butadiene rubber, Viton rubber and EPDM rubber with a mass ratio of 4:2:4;
[0037] 40 parts of reinforcing filler, said reinforcing filler comprising fumed white carbon black, ceramic powder and nano-calcium carbonate with a mass ratio of 2:2:1.
[0038] 8 parts of vulcanizing agent; said vulcanizing agent comprises benzoyl peroxide, hexamethylenediamine and dicumyl peroxide in a mass ratio of 4:2:4.
[0039] 6 parts of vulcanization aids, the vulcanization aids include magnesium oxide, zinc stearate and pentaerythroxylated glycol in a mass ratio of 1:1:0.5.
[0040] Anti-aging agent 5 parts.
[0041] The preparation method of the above-mentioned durable rubber sheet for photovoltaic laminator, the process conditions of one-stage vulcanization are: temperature 155°C, pressure 5PMa, time 30min, and ...
