Description
Technical field
A kind of preparation method of anti-blocking environmentally friendly sand paper, belongs to technology coated abrasive tool technical field.
Background technology
Existing sand paper coating formula is mostly solvent-borne type, and environmental pollution is serious.Sand paper coating generally uses stearic acid at present
Salt is main material mixture ratio, and stearate is white powder, not soluble in water, ethanol and ether, and is dissolved in toluene, benzene and turpentine oil
Deng organic solvent.But organic solvent environmental pollution is serious, operator's health is also endangered.Make stearic acid not soluble in water
Salt, coating is prepared without using organic solvent, its difficulty is very big.Existing sand paper coating formula organic solvent usage amount is big, easily
Volatilization, formula are unstable.For organic solvent in addition to environmental pollution is serious, its evaporation rate is very fast.Matched somebody with somebody with organic solvent
The sand paper coating formula of system, in coating process, because the volatilization viscosity B coefficent of organic solvent is very fast, formula is extremely unstable
It is fixed, cause largely to waste, preparing the desired stability for solving formula of sand paper coating using organic solvent can not possibly realize substantially.It is existing
There is the change of sand paper coating formula proportioning greatly, coating weight is uncontrollable.The state that stearate is dissolved in organic solvent is different, using having
Its proportioning of solvent preparation sand paper coating can not be completely the same, and the coating formula of same viscosity, the dosage of its organic solvent may
Due to the difference from hard hydrochlorate, difference is very big, so can not accurately control coating weight.Use different formulation ratios
Coating formula, it is unanimously extremely difficult for controlling coating weight.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of without using organic solvent, painting

The blocking preventing coating that the blocking preventing coating of the present invention is prepared by special process of the present invention, which is coated with, to be formed, the formula of blocking preventing coating
It is the key technical feature that the present invention is achieved with order by merging.1st, it is water that the environmentally friendly blocking preventing coating, which is formulated its solvent, is not had
Any organic solvent, it is environmentally safe, operator's health is not influenceed.Water is used to prepare blocking preventing coating as solvent,
Mainly by step 1）, step 2）, step 3）To realize.
Step 1）The surface tension of water or interfacial tension are reduced by adding wetting agent, allows the water to be deployed in hard hydrochlorate
On surface, or hard hydrochlorate surface is penetrated, and hard hydrochlorate is soaked.
Step 2）By adding dispersant adsorption in the surface of stearate particle, make the stearate particle surface of cohesion
It is easy to moisten, dispersant can make stearate particle surface form bilayer structure, and outer layer dispersant polar end has with water
Compared with strong affinity, add the degree that stearate particle is spontaneously wet out by water, and make between stearate particle because of electrostatic repulsion and
It is remote, make system uniform, suspendability increase, do not precipitate, make whole system physico-chemical property the same.
Step 3）There is fabulous adhesive force on stearate by adding the specific bleeding agent of the present invention, by effectively oozing
Thoroughly, the effective composition with blocking preventing coating is had an effect, and makes each ingredient stability of recipe more preferable, it is more difficult layering and
Separate out.
2nd, after the completion of the formula of blocking preventing coating used is prepared, viscosity B coefficent is almost unchanged, in stable condition to waste.It is logical
Cross and replace organic solvent with water, non-volatile under normal condition so as to realize, viscosity does not change.
3rd, the formula of blocking preventing coating used is prepared according to identical proportioning and completed, and its viscosity will not differ too many, Ke Yijing
Really control coating formula solids content, so as to reach stable application dose-effect fruit.
Preferably, step 1）Described in wetting agent be anionic surfactant aliphatic acid or/and fatty acid ester sulphur
Hydrochlorate.Preferable wetting agent can preferably allow the water to be deployed on hard hydrochlorate surface compared to other wetting agents, or penetrate
Hard hydrochlorate surface.
More there are choosing, step 1）Described in wetting agent be aliphatic acid and fatty acid ester sulfate in mass ratio 23 ~ 37：8~
12 mixing wetting agent.The wetting agent of optimum ratio form can reach the synergy that the present invention most adapts to, and make hard hydrochlorate
Wetting reaches optimum efficiency.
Preferably, step 2）Described in dispersant disperse for anionic fatty acid dispersant, aliphatic amide type
Agent and/or lipid dispersion agent.Preferable dispersant can preferably be adsorbed in stearate particle compared to other wetting agents
Surface, the stearate particle surface of cohesion is set to be easier to moisten, effect is more preferably faster.
It is furthermore preferred that step 2）Described in dispersant be anionic fatty acid dispersant and aliphatic amide type point
The mixed dispersant of powder.Preferred dispersant can reach the synergy that the present invention adapts to, and make system more uniform,
Suspendability is more preferable.
It is further preferred that step 2）Described in dispersant be anionic fatty acid dispersant and aliphatic amide
Class dispersant in mass ratio 56 ~ 65：5 ~ 11 mixed dispersant.Most preferably dispersant proportioning of the invention, can reach optimal
Synergy, reach the optimal dispersion effect of the present invention.
Preferably, step 3）Described in bleeding agent gather for non-ionic surface active AEO and alkyl phenol
Oxygen ethene rice ether in mass ratio 10：53 ~ 58 mixing bleeding agent.Preferable bleeding agent adhesive force on stearate is best, makes
Each ingredient stability of recipe reaches the best condition of the present invention.
Preferably, step 4）Described in hard hydrochlorate be calcium stearate, magnesium stearate or zinc stearate.Various stearic acid
Salt can well adapt to present invention process, and environmentally friendly sand paper blocking preventing coating is made.
Preferably, described blocking preventing coating presses 300 g/m2~350g/m2Applied amounts be coated on matrix.It is preferable to apply
Amount can better ensure that the blocking-proof result of sand paper.
Compared with prior art, possessed beneficial effect of the invention is：The coating of the environmentally friendly sand paper of the present invention uses
Environmentally friendly blocking preventing coating prepared by a kind of special process, it is water that the environmentally friendly blocking preventing coating, which is formulated its solvent, without any organic solvent,
