Present embodiment is to prepare the aqueous peelable glue of no-solvent type, and carried out to it using comparison, each to be embodied
The raw material components of example feed intake in parts by weight by following:
It is prepared using above-mentioned raw material proportioning, and by following process, specific steps are as follows: press raw material weight number
Proportion, water-based acrylic resin and waterborne polyurethane resin are added into container, and be 300-500r/ in revolving speed with dispersion machine
Under min (revolving speed is implemented respectively in various embodiments, and since 300r/min, every difference is the implementation of 12r/min value)
Dispersed, meanwhile, by the proportion of raw material weight number, be added respectively into container it is anti-be adhered auxiliary agent, thickener, defoaming agent,
Levelling agent and water, after being added completely into, the revolving speed of dispersion machine is adjusted to 800-1000r/min, and (revolving speed is in different embodiments
Middle to implement respectively, since 800r/min, every difference is the implementation of 12r/min value), (time can basis by dispersion 20-30min
Disperse the actual conditions value of each stock dispersion) to get to aqueous peelable glue.
Later, each resulting aqueous peelable glue ink pH is tested with accurate pH test paper, then uses spray gun spraying in PC, no
Become rusty steel, glass, on aluminium, the product after film forming is soaked in the water of room temperature by 60 DEG C of baking 3min film forming by film thickness 20-60um
In for 24 hours, remove film, the result of each embodiment thereafter are as follows:
As can be seen from the above results, the aqueous peelable glue pH value that present embodiment technical solution obtains is on 7.0 left sides
The right side, and coalescing agent is not added in preparation process, reach really without organic solvent, has realized Diamond Search discharge and low gas
The effect that taste distributes；Meanwhile the aqueous peelable glue toasts 3min at 60 DEG C and can form a film, and can also place at normal temperature
30min film forming, and film layer water resistance is good after film forming, directly tears when taking off film, so that pass through the aqueous peelable glue
High in machining efficiency and energy-saving and environmental protection, easy to operate, similar product has preferable advantage on the market for comparison.
