Dispatch of Chinese paint net / Joncryl95 is osmotic strong, through experimental discovery, suit priming paint of the path that become a head (sealed priming paint) , can close effectively material of poriferous, loose bottom, wait like the fiber with strong water imbibition, but because solid is contained very low, reason paint film is very thin, need for many times (3 above) spray ability achieves certain paint film result. The course fumbles for many times and experiment, can use this latex to do a path priming paint to close at present bottom material, next again spray is other and plump degree of a bit good priming paint, again spray face lacquer, can prevent superstratum paint film to follow priming paint cave in, make thereby paint film is met more level off is smooth. Additional, joncryl95 can mix the colorant of ability in swimming that besmear of the type that do the United States installs with alcohol of third of water, different, spray, sassafras mop but, adherent strength is good, the force that exhibit quality is powerful, dry rate is rapid.
Acrylic latex Joncryl537 is contained as a result of solid tall, the priming paint that do Qing Dynasty closes the gender is better also, paint film is fine into film, it is good to shed smooth sex, watch doing is fast, make an appointment with 12min left and right sides, pressure work to be controlled for 45min, and transparency, hardness (HB) , adherent force (4B) it is better to wait, flexibility is better (2mm) , impact resistance is better (12Kg.cm - 1) but, burnish sex is a bit poor, the burnish after 1.5h sticks sand paper. And make white priming paint, impact resistance is good (18Kg.cm - 1) , hardness is tall (F) , burnish sex is good, adherent strength is better (3B) . But arrive at present till the experiment, after discovering white priming paint sets period of time (50 ℃ , 14d) can produce the phenomenon that divide water, and hard precipitation happens.
From Joncryl1980 of latex of cross-linking acrylic acid, because its Tg is taller, reason needs to add the more auxiliary that become film (the 10wt ％ of whole recipe content is controlled) , ability forms good paint film effect, and if hydrophoby and hydrophily become velar auxiliary with 5:3scale mixes add, the effect is better. For many times after the experiment, knowable, level off of this latex paint film is smooth, and burnish is tall, can amount to 90 ％ above and not loss of gloss (50 ℃ oven, the 7d after 4h or normal temperature get right on the job) , paint film hardness is taller, can amount to HB (Germany pencil of 3 water chestnut, white Ju sticks face board, 7d) , adherent force actors or actress (5B) , flexibility is good (1mm) , and have be able to bear or endure very well ability in swimming (5, HG/T3828-2006) , it is good to fight adhesion sex (MM;B0, MB;A0, HG/T3828-2006) . Reason we think this latex suits to make paint of high smooth area. But at present experimental result looks, dry time is slower.
Comment on: Joncryl95 suits the path that become a head to close paint of priming paint, sassafras, although Joncryl537 does sex of priming paint burnish, close gender, stream smooth sex, transparency is very good, but because cost is higher, can take no account of temporarily, joncryl1980 suits to make paint of high smooth area very much, but dry time is slower, but readjust recipe (basically begin from the auxiliary that become film) , raise dry rate appropriately below the premise that does not affect other integral performance.
