Description
Technical Field
The invention belongs to the technical field of art pigments, and particularly relates to a preparation method of an acrylic painting pigment with an antique repairing effect and a pigment thereof.
Background
The acrylic paint is a new paint formed by mixing chemical synthetic acrylic emulsion, pearl color powder, preservative, auxiliary agent and filler, which appear in the 60 th century. The main characteristic of the propylene painting is that the propylene painting pigment is adopted for painting. The polymeric acrylic pigment itself is water-soluble and forms a film having water resistance after drying. The color is bright, the chemical property is stable, and each layer of pigment is mutually adhered to form transparent, semitransparent, semi-opaque and unclear, and the paint has strong adhesive force, good weather resistance and durability.
Painting products of oil painting, watercolor, gouache and other pigments can be worn and damaged over time, the same or similar color is difficult to find to repair or similar color to repair the worn and damaged position, and the characteristics of bright color, bright color and the like of the existing propylene painting pigment are not suitable for repairing, so that the antique repairing effect is poor.
In order to solve the problems in the prior art, the pigment is finer and finer by adding carboxymethyl cellulose and calcium carbonate; the silane coupling agent is selected, so that the color of the prepared pigment can be kept longer, the color is not easy to fade, but the problem of how to repair in ancient ways is not solved in practice. The acrylic additive with perfluoroalkyl is introduced to reduce cracking and improve the corrosion resistance of the pigment; however, the surface area of the outer layer saccharide of the carboxymethyl cellulose and the binding agent in the form of granular particles is large, so that a large amount of air and water are easily adsorbed, and the problem of picture damage caused by picture foaming and peeling phenomena is caused.

Further, in S4, the fusion material is an acrylic emulsion.
Preferably, the acrylic emulsion is a sh9015 acrylic polymer emulsion or a high temperature resistant CH-10912 acrylic polymer emulsion.
Further, in S4, the viscosity modifier is hypromellose. (the hydroxypropyl methylcellulose plays roles of water retention, adhesion and lubrication, avoids the phenomena of dry cracking and dehydration caused by excessively rapid water loss, and on the other hand, enhances the adhesive force of the filler and reduces the phenomenon of color cross in the painting process).
In order to improve the compatibility of various molecules in the fusion material and pigment slurry, reduce the probability of adsorbing air and water molecules of a finished product, improve the stability of a network structure formed by hydrogen bonds, avoid cracking of the pigment due to stress generated by stretching or shrinking of a high molecular chain in the drying process, avoid layering, degumming and the like, the invention provides the following preferable scheme for preparing the fusion material.
Further, in S4, the fusion material is prepared by the following steps:
mixing inorganic gel and acrylic emulsion to obtain mixed slurry, stirring and heating, wherein the maximum heating temperature is limited to 70-80 ℃; taking the time required by the temperature of the mixed slurry to rise by 1,3 ℃ when the mixed slurry is heated as interval time T, and collecting the pH value, the temperature value and the viscosity value of the mixed slurry in real time;
since too high a temperature may cause the acrylic emulsion to gel, the activity and viscosity decrease, the maximum temperature of heating is limited to 70-80 ℃;
adding an alkali regulator in a preset proportion into the mixed slurry every interval time T to improve the pH value of the mixed slurry, and if the moment meeting the low-viscosity peak condition is detected, recording the temperature value acquired at the moment meeting the low-viscosity peak condition as the low-viscosity peak temperature and stopping adding the alkali regulator; (i.e. if the instant i is the instant satisfying the low-viscosity peak condition, the temperature value acquired at the instant i is recorded as the low-viscosity peak temperature); or if the current temperature is greater than or equal to 70-80 ℃, recording the current temperature value as the viscous low peak temperature and stopping adding the alkali regulator;
the mixed slurry at this time was used as a prepared fusion, and the pH at this time was designated as the viscous low peak pH.
The preset proportion is 0.01% -0.05% of the mass of the mixed slurry;
(because the pH value is relatively higher when the viscosity-low peak condition is met, the fusion material is alkaline, and free H in the fusion material + Proton-less, -NH in acrylic emulsion 2 Will not be substantially identical to H + Is combined into-NH 3 + Thus no or less-NH 3 is produced + And carboxylate-COO - Due to the mutual absorption of yin and yang ions between the twoThe ionic bond structure which reduces the compatibility is formed, and the difference of the sensitivity of the inorganic gel to the viscosity of the pH value influence and the sensitivity of the acrylic emulsion to the viscosity of the pH value influence are large, so that the viscosity of the fusion material is relatively low, the acrylic acid and the inorganic gel are in an ingenious viscosity balance state, the compatibility of the products after the acrylic acid and the inorganic gel are blended is improved to a certain extent, the viscosity of the acrylic acid and the inorganic gel is in a viscosity low peak balance state, and the compatibility of the blending is most suitable, so that the compatibility of various molecules in the fusion material and pigment slurry is improved to a certain extent);
the viscous low peak condition is as follows: pa1 (i) < pa1 (i-T) and pa1 (i) < pa1 (i+T);
or alternatively, the process may be performed,
the viscous low peak condition is as follows: pa1 (i) < pa1 (i-T) and pa1 (i) < pa1 (i+T) and pa1 (i) is less than or equal to PaMPa (i); (because the viscosity is changed in many cases and is not changed linearly, because raw material impurities, uneven stirring, uneven heating and the like can generate a plurality of discrete viscosity changes, the preferable viscosity-reduced peak condition can effectively filter out low peak values of fluctuation generated by nonlinear decrease of the viscosity value when the pH value of the mixed slurry is increased, and the accuracy of monitoring the viscosity-reduced peak temperature is improved);
wherein pa1 (i) is the viscosity value of the mixed slurry collected at i (similarly, pa1 (i-T) is the viscosity value collected at i-T, pa1 (i+t) is the viscosity value collected at i+t), the time when the alkali regulator starts to be added is recorded as TS1, i is any time from TS1 to the current time, i.e., i is a variable from TS1 to the current time; paMPa (i) is the viscosity-low peak of the mixed slurry at time i;
the calculation method of the viscous low peak value Pampa (i) comprises the following steps:
wherein j is the serial number of the viscosity value of each mixed slurry collected from the TS1 moment to the i moment; ni is the total number of viscosity values of the mixed slurry collected from TS1 time to i time; paM (j) is the minimum of the j-1 th collected viscosity value and the j+1 th collected viscosity value; MGpa {1, j-1} is the smallest value among all viscosity values collected from the viscosity value of the 1 st collection from the TS1 moment to the corresponding collection moment of the viscosity value of the j-1 st collection; MGpa { j+1, ni } is the minimum value of all the viscosity values collected from the j+1st collected viscosity value to the corresponding collection time of the Ni-th collected viscosity value; (if either one of MGpa {1, j-1} or MGpa { j+1, ni } has a value of 0, then the value of |MGpa {1, j-1} -MGpa { j+1, ni } | is set to 0);
the principle is as follows: since the viscosity of the acrylic emulsion becomes gradually higher with an increase in pH, since most of the carboxyl groups provided to the macromolecular chains by acrylic acid are located in the surface layer of the particles, when neutralized with a base, the carboxyl groups ionize to produce negatively charged carboxylate (-COO) - ) The particles are mutually repelled to form a linear stretching layer, and simultaneously, a large amount of water molecules enter the stretching layer under the action of static electricity and hydrogen bonds, so that the apparent viscosity is increased due to the relative reduction of a particle apparent volume increasing dispersion medium; when the pH is increased to a certain degree, the acrylic ester monomer in the acrylic emulsion is hydrolyzed, so that the activity and viscosity of the acrylic emulsion are reduced, and the acrylic emulsion cannot be excessively alkalized; in addition, since the sensitivity of the viscosity of the inorganic gel to temperature and pH and the acrylic emulsion difference are large, the viscosity-reduced peak temperature in the viscosity equilibrium state after blending is difficult to obtain by directly measuring the temperature or pH due to the above-mentioned effects of the mixed slurry, the material ratio of the mixed slurry, impurities and the like, and thus it is necessary to accurately detect the viscosity-reduced peak temperature by this scheme.
The above principle can be seen in reference [1]:
[1] blue Yun Jun, provisions on the influence of pH on the emulsion polymerization of acrylic esters [ J ]. Proc. Of the northwest light industry, 1994 (03): 422-427.
Note that: in the case of the blend obtained by the above method, stability at the time of blending the materials and maximum compatibility can be ensured by the following preferred method, and the compatibility may be lowered if the blend is directly stirred.
Further, in S4, the specific method for adding the fusion material and the viscosity modifier into the pigment slurry and stirring uniformly includes the following steps:
the temperature of the pigment slurry is regulated to the viscosity-low peak temperature, the pH value of the pigment slurry is regulated to the viscosity-low peak pH value through an alkali regulator, and then the fusion material and the viscosity regulator are sequentially added into the pigment slurry to be stirred to obtain an activated slurry, and the pH value, the temperature value and the viscosity value of the activated slurry are collected in real time;
adding an acid regulator in a preset proportion into the activated slurry every interval time T to reduce the pH value of the activated slurry, and stopping adding the acid regulator if the moment meeting the viscosity peak condition is detected; stirring the activated slurry for 10-15 minutes from the moment, and cooling to room temperature to obtain uniformly stirred colored slurry, namely, propylene painting pigment which is fed into a vacuum machine;
preferably, the pH is adjusted to neutral by adding an amine neutralizer after stirring the activated slurry for 10 to 15 minutes.
(free H in the slurry is activated due to the tendency of pH to be neutral or acidic when the viscosity peak condition is satisfied) + Increase of-NH in acrylic emulsion 2 Will be mixed with H during stirring + Is combined into-NH 3 + Formed of-NH 3 + And activating carboxylate-COO in the slurry - The ionic bond structure is bonded with the polymer chains in the activated slurry, the viscosity of the activated slurry is in a viscous peak equilibrium state, the blending effect with other molecules is best, and the molecular gap is small after blending, so that the adsorption of the activated slurry to air and water is reduced, and the effects of preventing dry cracking and having high color saturation are also considered.
Wherein, the peak sticking condition is: pa2 (k) > pa2 (k-T) and pa2 (k) > pa2 (k+T);
or alternatively, the process may be performed,
the peak sticking condition is as follows: pa2 (k) > pa2 (k-T) and pa2 (k) > pa2 (k+T) and pa2 (k) > PaWpa (k); (because the viscosity change is not linear in many cases, and because of raw material impurities, uneven stirring, uneven heating and other factors, discrete viscosity change can be generated, the preferable viscosity peak condition can effectively filter out the high peak value of fluctuation generated by nonlinear increment of the viscosity value when the pH value of the fusion material is reduced, and improve the accuracy of monitoring the viscosity peak value);
wherein pa2 (k) is the viscosity value of the activated slurry collected at the moment k, and the moment when the acid regulator starts to be added is recorded as TS2; k is a variable from the TS2 time to any time between the current time, that is, k is a time between the TS2 time and the current time; paWpa (k) is the peak viscosity of the activated slurry at time k;
the calculation method of the sticky high peak value PaWpa (k) comprises the following steps:
wherein q is the sequence number of the viscosity value of each activated slurry collected from the TS2 moment to the k moment; nk is the total number of viscosity values of the activated slurry collected from TS2 time to k time; paW (q) is the maximum value among the viscosity value of the q-1 th acquisition and the viscosity value of the q+1th acquisition; WGpa {1, q-1} is the maximum value of all the viscosity values collected from the viscosity value of the 1 st collection at the time TS2 to the corresponding collection time of the viscosity value of the q-1 th collection; WGpa { q+1, nk } is the maximum value of all the viscosity values from the viscosity value acquired at the q+1th time to the viscosity value acquired at the corresponding acquisition time of the viscosity value acquired at the Nk th time; (if either one of WGpa {1, q-1} or WGpa { q+1, nk } has a value of 0, the value of |WGpa {1, q-1} -WGpa { q+1, nk } | is set to 0).

Wherein, in the mixed slurry, the mass ratio of the inorganic gel to the acrylic emulsion is as follows: 1:2 to 5.
Preferably, in S2, the filler powder further includes one or more of platy mica powder, needle-shaped glass fiber and attapulgite.
