Abstract
The invention discloses a kind of hydrogenated nitrile-butadiene rubber and metallic framework adhesion technique, comprise the steps: 1) with existing pre-treating technology, pre-treatment is carried out to skeleton; 2) paracril tackiness agent TD870 and ethanol are carried out dip-coating 30s ~ 60s by after the dilution proportion of 1:7 ~ 10 to skeleton, 170 ~ 190 degrees Celsius of bakings are for subsequent use after 4 ~ 6 minutes; 3) by primary coat tackiness agent Megum538 and dimethylbenzene with dip-coating step 2 after 1:5 dilution proportion) process after skeleton 30 ~ 60s; 4) 100 DEG C of heating cures 4 ~ 6 minutes.The common butadiene-acrylonitrile rubber tackiness agent TD870 of the use dilution of novelty of the present invention replaces former hydrogenated butyronitrile special bottom coating adhesive P-11-EF, and common butadiene-acrylonitrile rubber binder performance stablizes easy handling, adds the stability of skeleton; Improve Dilution ratio because the stable table of primary coat is coated with, stopped sheet framework and superposed coherent phenomenon; Production process adopts heating cure, highly shortened the production cycle.
Description
Technical field
The present invention relates to a kind of hydrogenated nitrile-butadiene rubber and metallic framework adhesion technique.
Background technology
Due to the special construction of hydrogenated nitrile-butadiene rubber, hydrogenated nitrile-butadiene rubber and metallic framework poor adhesion, the adhesive specially viscosity adopted is comparatively large and need base map to add table to be coated with, coating processes is complicated, if sheet framework material adopts dip-coating easily to cause material to superpose and is bonded together, the use of operation after impact, be coated with according to hand, efficiency is too low is unfavorable for that batch production is carried out.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hydrogenated nitrile-butadiene rubber and metallic framework adhesion technique; This technique can make hydrogenated nitrile-butadiene rubber and metallic framework firm engagement; Skeleton can drop into sulfuration and use after batch pre-treatment, dip-coating tackiness agent, baking together with rubber.
For solving the problems of the technologies described above, a kind of hydrogenated nitrile-butadiene rubber of the present invention and metallic framework adhesion technique, comprise the steps:
1) with existing pre-treating technology, pre-treatment is carried out to skeleton;
2) paracril tackiness agent TD870 and ethanol are carried out dip-coating 30s ~ 60s by after the dilution proportion of 1:7 ~ 10 to skeleton, 170 ~ 190 degrees Celsius of bakings are for subsequent use after 4 ~ 6 minutes;
3) by primary coat tackiness agent Megum538 and dimethylbenzene with dip-coating step 2 after 1:5 dilution proportion) process after skeleton 30 ~ 60s;
4) 100 DEG C of heating cures 4 ~ 6 minutes.
Preferably, step 2) in, the weight ratio of described tackiness agent TD870 and ethanol is 1:8.
Preferably, step 2) in, described time of immersion is 45s, and storing temperature is 180 DEG C, and baking time is 5 minutes.
Preferably, in step 4), the heating cure time is 5 minutes.
Described paracril tackiness agent TD870 is commercially available prod, and there is this product of production and sales in such as Korea S south of the River chemical company, and Shanghai Bai Qi Industrial Co., Ltd. also has sells this product.
Described primary coat tackiness agent Megum538 is commercially available prod, and such as U.S.'s ROHM AND HAAS product has this product of production and sales, and upper seascape favour trading company also has sells this product.
The present invention has following beneficial effect:
The common butadiene-acrylonitrile rubber tackiness agent of the use dilution of novelty of the present invention replaces former hydrogenated butyronitrile special bottom coating adhesive, and common butadiene-acrylonitrile rubber binder performance stablizes easy handling, adds the stability of skeleton; Improve Dilution ratio because the stable table of primary coat is coated with, substantially stopped sheet framework and superposed coherent phenomenon; Production process adopts heating cure, highly shortened the production cycle.
