Abstract
A stripper of high temperature cured film on printing Ni screen is prepared from organic acid, corrosion inhibitor, surface active agent and expander. Its preparing method can be finalized by one step process of socking for de-filming and de-blinding so reuse for printing Ni screen in circulation can be effectively realized.
Description
Technical field:
The present invention relates to technology that the printed nickel net hot setting film that is applied in the ROTARY SCREAM PRINTING is peeled off, comprise remover and stripping means.
Background technology:
The printing in textiles mode has at present: copper roll marks flower, PLATE SCREAM PRINTING, ROTARY SCREAM PRINTING, manual platen stamp, Computerized ink-jetting stamp etc., wherein the ROTARY SCREAM PRINTING development is very fast.Along with short run, many kinds, deliver goods a large amount of productions of export order soon, the nickel screen demand of different size can increase substantially, present national cylinder consumption is about ten thousand/year of 200-250.
Owing to use the high-molecular photosensitive material in the cylinder system network process, form one deck densification, certain flexible polymeric membrane is arranged on nickel system net base surface, this tunic has very high brute force behind overcuring, be bonded with very high peel strength with the nickel screen surface.At present this tunic is not still had good film and peel off measure, therefore, present global ROTARY SCREAM PRINTING just can only be used once with nickel screen, unless process identical colored type order.The utilization factor of cylinder is extremely low, cause the huge waste of nickel metals resources, simultaneously because long-term these nickel rounding nets of stacking cause huge environmental pollution, take huge space and stack the maintenance management expense for a long time very big, directly cause the rising significantly of potential production cost.
The situation of relevant information, data, magazine report up to now, discarded printed nickel net demoulding and recycling aspect, Germany Wei Erte image technology company limited adopts the equipment of being made up of 20 micro nozzle UHV (ultra-high voltage) hydraulic giants, brute force by high-pressure water sprays the cured film of destroying the nickel screen surface, realizes cleaning demoulding.This processing belongs to the cylinder demoulding and the two-step process that silently dissociates, and demoulding efficient is low.Also there be the equipment and the supporting cylinder surface calibration equipment of similar functions in Japan, and processing also belongs to the cylinder demoulding and the two-step process that silently dissociates.Above micro nozzle UHV (ultra-high voltage) hydraulic giant equipment manufacturing cost costliness.China Zhejiang Jinchang company adopts superlaser to burn the principle of cured film, also make and released laser film peel-off device model machine, this model machine can be peeled off cured film, but its efficient is too low, peeled off one in the nickel screen 4-5 of the 1850mm door width of cloth hour, and laser burns a large amount of harmful gases of generation, contaminated environment.Belong to the cylinder demoulding and the two-step process processing of silently dissociating, still can't promote the popularization use now.
Summary of the invention:
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of high-temperature stripping agent of curing membrane for printed nickel net, its compound method and application thereof are provided, using with the efficient circulation that realizes printed nickel net, and do not have pollution-free, the quick demoulding of burn into.
The technical scheme that technical solution of the present invention adopted is:
High-temperature stripping agent of curing membrane for printed nickel net of the present invention is composite with organic acid, corrosion inhibiter, surfactant and swelling agent;
Its raw material is by weight formed:
Lactic acid 5-10 part,
Gluconic acid 5-10 part,
2-phosphonic acids-1,2,4-tricarboxylic acids (PBTCA) 1-2 part,
Amino Trimethylene Phosphonic Acid (ATMP) 2-4 part;
To aluminium, nickel metal have corrosion inhibition corrosion inhibiter 2-8 part,
Non-ionic surfactant: alkyl polyglycoside 2-4 part;
Phenols swelling agent: 10-15 part;
Water: 38-68 part.
The preparation of high-temperature stripping agent of curing membrane for printed nickel net of the present invention is to operate as follows: at first add lactic acid, gluconic acid, 2-phosphonic acids-1,2,4-tricarboxylic acids (PBTCA) and each organic acid composition of Amino Trimethylene Phosphonic Acid (ATMP) successively to dissolving fully under stirring condition in water; Add phenols swelling agent component then while stirring to dissolving fully; Add the corrosion inhibiter component again to dissolving fully; Add non-ionic surfactant component at last to dissolving fully; At room temperature left standstill 3 hours, and filtered discharging then and promptly finish preparation.
The physicochemical property of remover of the present invention is as follows:
Outward appearance: light yellow transparency liquid; Type: the moon/nonionic;
Effective constituent: 38% ± 2; Dissolubility: can be miscible with any ratio with water;
PH value: 2 ± 0.5 (38% ± 2 effective constituents); Stability: permanently effective under the room temperature condition;
Stripping means of the present invention is a demoulding and take off that silently a step is finished operation as follows:
A, be immersed in the printed nickel net of processing to be stripped in the remover fully;
Leave standstill under b, the employing normal temperature, separate fully until cured film; Or adopt indirect heating to make remover at the uniform velocity be warming up to 60-65 ℃ from room temperature, keep this temperature to separate fully until cured film;
C, taking-up cylinder are peeled off the cured film of having separated, and clean the demoulding cylinder with HP shower, and the draining hot-air seasoning is vertical and deposits; Take off cylinder silently, cleaning silently locates to solidify the residual film of glue, and demoulding is promptly finished.
The present invention is according to physical chemistry and electrochemical principle, based on technology and environmental protection parameters such as the molecular structure of nickel matter, alumina based material chemical stability, decay resistance and cured film, swelling behaviors, the multiple synergy demoulding component of selecting to contain the functional group close or identical with the cured film material structure is made remover.This functional compound by molecular thermalmotion at corresponding nickel screen material surface scattering and permeating, each micropore of surfaces externally and internally or fault location in cured film form well-regulated directed absorption alignment layer, intermolecular various power is jointly to the cured film performance traction stretching action opposite with adhesion, and the rapid swelling of cured film is also progressively peeled off its absorption surface.
The invention belongs to the efficient demoulding of materialization combination, can realize demoulding, take off silently a step and finish.Compared with the prior art, beneficial effect of the present invention is embodied in:
1, remover of the present invention can be reused, Nonpoisonous, non-environmental-pollution.The cured film that strips down is insoluble in the remover, very easily rejects from stripper solution, makes remover can repeat repeatedly to use.Compare with the laser burning method, pollution-free to operating environment.Do not have discharging, according to the normal running nonhazardous.
2, the demoulding cost is low.Every cylinder consumes the 0.30kg remover only, is roughly equal to 16.50 yuan of Renminbi.According to initial estimate, the direct cost of every nickel screen demoulding is approximately 10% of net base price, easily accepts for market.
3, demoulding efficient height, corrosivity is minimum.Contain among the present invention nickel/aluminium is played the inhibition component, related material is all considered the material corrosion resistance.
4, stripping means of the present invention is under 60-65 ℃ of dipping temperature condition, and the disengaging time of its cured film only needs about 30 minutes.
Embodiment:
High-temperature stripping agent of curing membrane for printed nickel net in the present embodiment is composite with organic acid, corrosion inhibiter, surfactant and swelling agent; Its raw material is by weight formed:
