    Key tips: paint formula: Table 1 raw material name and specification of general epoxy primer, component A, bisphenol A, low molecular epoxy resin (E44), 20-25, industrial liquid phenolic resin, 5-10, industrial zinc molybdate, 1-3, industrial zinc phosphate, 2-5, industrial calcium phosphate, 4-6, industrial composite iron titanium powder, 7-9, industrial iron oxide red, 5-7, industrial sericite powder, 3-5, industrial grade Talc 12-18 industrial organobentonite sd-20.25-1.0 defoamer Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: coating formula: Table 1 raw material name and specification of the coating formula of general epoxy primer component a component bisphenol a low molecular epoxy resin (E44) 20-25 industrial liquid phenolic resin 5-10 industrial zinc molybdate 1-3 industrial zinc phosphate 2-5 industrial calcium phosphate 4-6 industrial composite iron titanium powder 7-9 industrial iron oxide red 5-7 Industrial sericite powder 3-5 industrial talcum powder 12-18 industrial organic bentonite sd-20.25-1.0 defoamer (byk066n) 0.1-0.5 epoxy silane coupling agent (KH-560) 0.1-0.5 xylene 5-8 butanol 1-2 B component cardanol modified phenolic amine curing agent (jt-6015a) 15-20 xylene 2-3 butanol 0.5-1 production method: Firstly, E-44 epoxy resin, liquid petroleum resin, xylene and butanol solvent are added for full stirring, then zinc molybdate, calcium phosphate, composite iron titanium powder, talcum powder and defoamer are added for high-speed dispersion, then iron oxide red and sericite powder are added for high-speed dispersion, and then sand until the fineness is less than 60 μ m, add organobentonite SD-2 slowly under low-speed dispersion, and then conduct high-speed dispersion, then adjust the viscosity to 800-1500 MPa · s with xylene and butanol mixed solvent, filter and package as component A Jt-6015a cardanol modified phenolic amine curing agent, xylene and butanol were stirred evenly and filtered to obtain component B The ratio of component A to component B is (4-5): 1 (mass ratio) Before use, mix component A and component B according to the above proportion, fully mix them, and use them after 15-25 minutes of static state The construction can be carried out by brush and spray The application period is 6 hours at 25 ℃ Performance test: test item performance index coating appearance is brown, coating smoothness / μ m ≤ 80 viscosity (rotational viscometer) / (MPA · s) 800-1500 solid content /% ≥ 85 adhesion / grade 1 impact resistance / cm 50 flexibility / mm 1 low temperature flexibility (- 5 ℃) / mm 11 hardness 2H wear resistance (500 g / 500 R) / mg ≤ 80 scrub resistance MEK / time ≥ 100 Water resistance (90 d), no blistering, no rust, no shedding, no salt water resistance (3% NaCl, 21 d), no blistering, no rust, no shedding, no vapor oil resistance (90 d), no blistering, no shedding, no distilled water resistance (30 d), no shedding, no alkali resistance (5% NaOH, 20 d), no blistering, no shedding, no acid resistance (5% H2SO4, 20 d), no blistering, no shedding, no moisture and heat resistance (1000 h) There is no obvious change in coating film, salt spray resistance (3000 h), no obvious change in coating film, no adverse phenomenon in matching with all kinds of top coats, storage stability (12 months) (component a), basically no precipitation in coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, Decoration knowledge and effect drawing of fireproof coating,
