Description
Technical field
The present invention relates to technical field of coatings, more particularly to water paint, and in particular to one kind scribble film one pack system zero
VOC water varnishes and preparation method thereof.
Background technology
Childhood be important period that intelligence development and artistic ability are sprouted, a main forms are exactly to scribble, and are applied
Crow is highly profitable to tap intellectual resources.In the case where not influenceing interior decoration, the anti-scribble film that scene is brushed arises at the historic moment, and scribbles
Film is that one piece of blank of making is brushed at scene on wall, and its size can arbitrarily make, and can be one piece or one side
Wall, it might even be possible to be a room, arbitrarily write for child, calculate, paint.Scene, which is brushed, makes blank and scribble film, is used for
Substitute existing frequently-used blackboard for education, teaching white board.Pollution caused by avoiding blackboard chalk-writing, eliminates purchase finished product
Waste caused by blank, projection screen, makes and work progress is environmentally friendly.For energy worsening shortages, environment worsening the present
My god, the popularization and application of aqueous graffiti film are also made that some contributions for environmentally friendly, energy-conservation, emission reduction.Film of scribbling simultaneously can also answer extensively
For the field such as billboard of office's metope, workshop, applied as blank, projection screen etc., by the throwing of scribble film production
Shadow wall, explanation can be write in project content, be a kind of more lively, more effective interaction mode.Blank paint is used to apply
The billboard of brush workshop, reduce the limitation of task writing, it is ensured that produce the accuracy of exchange.
Be commonly used for scribble film preparation is based on high-performance varnish, can be divided into poly- ammonia from the resin system of film forming
Ester, polyacrylate, polysiloxanes etc., traditional solvent-borne and water-based two class can be divided into from solvent species, from one pack system, two-component
With more components.The high-performance varnish prepared applied to scribble film and blank will meet the environmental requirement of scene brushing；Secondly
It is easy to construct, it is convenient and swift, there is extensive adaptability to base material；Also need to long service life, as case hardness will height,
Cracking will not be peeled off, easily recoating renovation；Above all there is good anti-graffiti property, white board marker person's handwriting is easily wiped clean, no
Mark.
Prior art mainly includes following problem：
1. the feature of environmental protection：Conventional clear varnish is ensures good filming performance, generally with a large amount of cosolvents or coalescents, this
Class material VOC (volatile organic compounds) has tremendous influence to health.Work as residence
When VOC in room reaches finite concentration, people can feel headache, Nausea and vomiting, weak etc. in the short time, occur when serious
Twitch, stupor, and liver, kidney, brain and the nervous system of people can be hurt, cause the serious consequences such as failure of memory.Apply
Expect national standard《Limits of harmful substances in GB18582-2008 indoor decorating and refurnishing materials interior wall coatings》The definition of middle VOC content be
Under 101.3kPa normal pressures, any initial boiling point is less than or equal to 250 DEG C of organic compound.It is it is, in general, that contained in material
VOC is fewer, and its harm to human body is slighter.Requirement in coating national standard to VOC content in interior wall coating is：It must not be higher than
120 grams every liter.Limitation of the developed countries to VOC content in coating is very strict.It is a kind of for European Union（Matt class）Coating
30 grams every liter must not be higher than, two classes（There is light class）200 grams every liter must not be higher than；And at home, the newest issue of State Environmental Protection Administration
Aqueous inner wall paint environmental labelling product authentication requesting regulation, interior wall dull finishing coat VOC must not be higher than 50 grams every liter, high smooth surface
Must not paint higher than 80 grams every liter.Solvent-borne type clear varnish product is gradually eliminated, and reduces the VOC in aqueous product, is opened
The product for sending out VOC even " Diamond Search " low is the concentration demand and technological difficulties in market.Common low film formation temperature resin is difficult to reach
To the requirement of case hardness and anti-scribble performance, and the water-base resin of higher film-forming temperature then needs the film forming of higher addition to help
Agent helps film forming.
In addition, the water-based isocyanate curing agent of existing market main flow two-component clear varnish product generally use to eye and
The stimulation and damage of the upper respiratory tract：Low concentration, which causes, sheds tears and coughs, and high concentration can cause furious swollen and chemical burn.
Schneiderian membrane can be destroyed, makes anosmia, upper respiratory tract mucosa can also cause chemical damage.Concentration more than 50mg/m^3, it can cause
Hydroderma, necrosis.In addition, still causing respiratory tract anaphylaxis to react, expiratory dyspnea and pulmonary edema are aggravated.How effectively to solve
Certainly.
Therefore, it is badly in need of the upgrading of environmental-protecting performance applied to the scribble film class product that market is filled behind child room finishing and interior.
2. application property：The common bi-component scribble varnish product in market needs to premix before construction, is applied after Site
Work, because two-component system has shorter working life（Pot life, it is common within 2-4 hour）, cause finally to construct
Quality is difficult control, and it is very long to solidify drying time as used high hydroxyl resin if, it is difficult to rapid curing uses, and Site construction
It is difficult to avoid to have many film defects, and bubble, shrinkage cavity, flake etc. are difficult to overcome.It is easy to the one pack system of high resistance to scribble performance
The varnish of construction is also prominent technological difficulties.
3. application performance：Final antigraffiti effect and performance is the main performance indications for weighing scribble varnish product, is had
A series of spot-resistant performance of relevant criterion and method the detection coating of other product scopes, such as HG/T 4756-2014 interior walls
Spot-resistant latex paint, children's aqueous inner wall paint, the resistance to scribble detection method of children furniture etc..This patent is straight using water-based crayon
It is connected on scribble film film forming to be scribbled afterwards, carries out wiping scoring after certain time, more can directly react actual application
In scribble performance.
4. other performances：Transparent scribble other performances of varnish such as surface drying time, scrub resistance, solvent resistance etc..
