Description
Technical field
The present invention relates to a kind of chemical industries, especially a kind of paint not easily occurring pin hole.
Background technology
Coating is a kind of material, and this material can be coated in article surface by different construction technologies, forms adhere well, has some strength, continuous print solid film.The film common name film of such formation, also known as paint film or coating.Belong to organic chemical industry's macromolecular material, the film formed belongs to macromolecular compound type.The classification of the Chemicals of passing through according to the modern times, coating belongs to fine chemical product.Modern coating is progressively becoming the polyfunctional engineering materials of a class, is an important industry in chemical industry.
When painting, easily there is at coating surface the needle point pore phenomenon that a kind of depression is revealed the exact details.This tip-like aperture is just as acupuncture aperture, and aperture is at 100 microns.Affect attractive in appearance, the subject matter reason producing it has one, plate surface process is bad, many wollines, wood thorn, fill difficulty; Two, bottom does not parch completely, just construction second time.Three, the paint prepared does not leave standstill for some time, and paint viscosity is high, and bubble is not eliminated.Four, one-off construction is blocked up.Five, solidifying agent, the supporting mistake of thinner; Six, solidifying agent add-on is too much.Seven, environment temperature and humidity is high; Eight, moisture content is high.
Summary of the invention
The present invention is intended to solve the problems of the technologies described above, provide a kind of paint not easily occurring pin hole, its strong covering power, toxicity is little, and solidifying agent is less, and anti-pin hole ability is good, construction stability is good, having defoamer can effectively suppress bubble to produce, lower to the requirement of construction environment, and its technical scheme adopted is as follows:
Not easily there is a paint for pin hole, it is characterized in that: its composition weight proportioning is:

Organic silicon modified by polyether is polyether siloxane copolymers obtained because of such as polyether segment in siloxane molecule.It is rapid that polysiloxane defoamer has froth breaking, press down the features such as bubble time length and safety non-toxic, polyethers defoamer good water solubility, high temperature resistant, strong basicity resisting is strong, but its antifoaming speed and to press down the bubble time all not satisfactory, be grafted on polysiloxane chain by condensation technology and introduce polyether chain, make it the advantage with two defoamers, become a kind of excellent property, the defoamer had wide application prospects.In the molecule of silicon ether copolymer, siloxanes section is oleophilic group, and polyethers section is hydrophilic group.In polyether segment, polyethylene oxide chain Energy Conservation is for wetting ability and whipability, and poly(propylene oxide) chain is energy-conservation provides hydrophobicity and seepage force, has stronger effect to reduction surface tension.The group of polyethers end group also has very strong impact to the performance of silicon ether copolymer.Common end group has hydroxyl, alkoxyl group etc.Regulate the relative molecular mass of siloxanes section in multipolymer, multipolymer can be made to give prominence to or weaken organosilyl characteristic.Equally, change the relative molecular mass of polyethers section, can increase or reduce organosilyl ratio in molecule, also can have an impact to the performance of multipolymer.Polyether Modified Polysiloxanes Defoaming Agent is easy to emulsification in water, is also called " self-emulsifying type defoamer ", time more than its cloud point temperature, loses the solvability to water and mechanical stability, and acid-and base-resisting and inorganic salt.Polysiloxane defoamers is usually suitably coordinated by dimethione and silicon-dioxide two main components and forms, take polydimethylsiloxane as the defoamer of base material be the defoamer that in antifoaming system, a class is desirable, be exactly because it is water insoluble, more difficult emulsification, polydimethylsiloxane is lower than carbochain hydrocarbon surface property, therefore lower than the usual tensio-active agent surface tension applied in textile industry.Simple polydimethylsiloxane suds suppressing properties is poor and slow, froth breaking effect needs silicon dioxide granule to strengthen, silicon dioxide granule to be taken in the air-water termination of foam by silicone oil and enters air bubble liquid-membrane due to its hydrophobicity, 90 ° are greater than with the foam contact angle of drop of tensio-active agent, thus force foaming liquid to arrange from solid hydrophobic particle surface, draw local foamy rapid drainage and cause breaking.Like this, due to synergy, two kinds of constituents create good defoaming effect.
