Description
Technical Field
The invention relates to the technical field of wood lacquer, in particular to water-based fireproof wood lacquer finish paint.
Background
With the development of economy, the improvement of environmental awareness and the improvement of the water-based wood paint technology, the water-based wood paint has become a development trend. With the promotion of the living taste of people and the high concern on health, the future home decoration and furniture coating markets are bound to be the water-based paint. The popularization of the water-based wood coating is very beneficial to the reasonable utilization of resources and the improvement of environmental sanitation. As the operability of the construction of the water-based wood coating is enhanced, domestic well-known decoration companies intend to use the water-based wood coating comprehensively, train painters to establish corresponding construction teams and initiate water-based movement. At present, the safety and environmental protection indexes of the paint are increasingly emphasized, and the water-based wood paint is gradually accepted by the market due to the characteristics of low harm and low pollution.
Although the water-based paint has the advantages of environmental protection and the like, the existing water-based wood paint has some defects: firstly, the drying of the water-based wood coating is greatly influenced by environment, weather and particularly humidity, and the surface drying time and the actual drying time are too long during normal use, so that the construction period is prolonged correspondingly, and meanwhile, the influence degrees of the surface drying and the actual drying are different, so that the paint surface is not smooth and the appearance effect is influenced; secondly, the existing common water-based wood paint is mainly prepared by adopting acrylic emulsion or polyurethane emulsion as a main film forming substance, the fireproof/fire-resistant performance is poor, and the paint film can catch fire, bubble, scorch, drop, pulverization, softening and other phenomena when meeting high temperature or burning, and can not be used normally. Therefore, it is desirable to provide a water-based fire-retardant wood paint finish to solve the existing problems.
Disclosure of Invention
In view of the above, the invention provides the water-based fireproof wood paint finish, which can accelerate surface drying and actual drying at the same time, and ensures that the surface of the constructed paint is smooth while the drying speed is high; and the fireproof performance is excellent in safety, environmental protection and long-term fireproof performance.
In order to achieve the technical effects, the invention provides a water-based fireproof wood paint finish, which adopts the following technical scheme:
the water-based fireproof wood paint finish comprises the following components in percentage by weight: 45-70% of water-based acrylic resin, 0.5-2% of water-soluble herbal extracted volatile oil, 1-4% of film-forming additive, 0.5-1% of polyether organic silicon defoamer, 0.4-1.5% of flatting agent, 10-25% of nano bauxite, 10-20% of flame retardant and the balance of deionized water;
the preparation method of the water-soluble herbal extracted volatile oil comprises the following steps: cutting dried herbaceous plant, soaking in water, placing in a steam distillation device, extracting by steam distillation, removing oil phase layer in distillate, distilling distillate repeatedly until there is no oil phase layer, adding a certain amount of sodium chloride or potassium chloride for salting out, extracting with organic solvent, and concentrating the extractive solution under reduced pressure in water bath at a certain temperature to obtain oily substance which is water soluble herbaceous extract volatile oil.
Furthermore, in the preparation method of the water-soluble herbal extracted volatile oil, the herbaceous plant is vanilla and/or schizonepeta.
Further, in the preparation method of the water-soluble herbal extracted volatile oil, the organic solvent is n-hexane and/or ethyl acetate.
Further, in the preparation method of the water-soluble herbal extracted volatile oil, dried herbs are cut up and soaked in water for 5 to 24 hours, the weight ratio of the herbs to the water is 1 to 6 to 30, and the herbs are placed in a steam distillation device for extraction for 2 to 8 hours.
Further, the addition amount of the sodium chloride or the potassium chloride is 2 to 15 percent of the weight of the distillate; concentrating the extractive solution under reduced pressure in water bath at 55-75 deg.C.
Furthermore, the particle size of the nano bauxite is 10-800nm.
Further, the flame retardant is a mixture of aryl phosphate and diphenyl phosphate, and the weight ratio of the aryl phosphate to the diphenyl phosphate is 1;
wherein the aryl phosphate comprises triphenyl phosphate and tricresyl phosphate;
the triphenyl phosphate accounts for less than 18% of the flame retardant by weight, and the thermal decomposition temperature of the flame retardant is above 250 ℃.
Further, the film-forming assistant adopts Filmer C40.
Furthermore, the polyether organic silicon defoamer adopts a Digao 810 defoamer.
Further, the leveling agent is a DSX 2000 series Newtonian leveling agent.
The technical scheme of the invention at least comprises the following beneficial effects:
1. in the stage of gradually closing and filling the particles, the waterborne acrylic resin spherical particles keep a dispersion state in the waterborne fireproof wood paint under the action of a double electric layer and shielding stability, after the waterborne fireproof wood paint is constructed, the water is gradually volatilized, and the polymer particles and the pigment particles which originally keep the dispersion state under the action of electrostatic repulsion and steric hindrance stability gradually close together but can still move freely;
in the stage, the volatilization of the water is similar to the volatilization of pure water and is constant-speed, and the volatile oil extracted from the water-soluble herbs can accelerate the volatilization of the water and directly accelerate the process of the stage, thereby achieving the effect of accelerating the surface drying;
in addition, the production raw materials for extracting the volatile oil from the water-soluble herbs are herbaceous plants, the amount is large, the production raw materials are easy to obtain, the adding amount in the raw material formula is small, the cost cannot be obviously raised, and the preparation method is simple, safe, environment-friendly and harmless.
2. In the particle fusion stage, along with further volatilization of water, the protective layer adsorbed on the surface of the polymer particles is damaged, the exposed particles are contacted with each other, the gap between the exposed particles is smaller and smaller, the volume of the paint film is shrunk, when the water is volatilized completely, the driving force is also disappeared, when the capillary tube is large, due to the effect of capillary tube efficacy, the capillary tube pressure is higher than the deformation resistance of the polymer particles, the stability of the particles is damaged, the particles begin to deform, and then the particles are aggregated and fused into a continuous coating film;
the stage is the key to whether the water-based paint can form a film, if the glass transition temperature (Tg) of the polymer is higher (in order to ensure that the coating film has good mechanical property, weather resistance and dirt resistance, the Tg value is generally not too low), the polymer is difficult to deform at a lower environmental temperature, so that the fusion process is hindered, and the film forming auxiliary agent can swell and soften the particles, so that the particles can be fused together more easily to form a continuous coating film, so that the effect of accelerating actual drying is achieved.
3. In the stage of film formation by mutual diffusion, permeation and crosslinking of polymer chain segments, the film-forming aid is gradually diffused towards the film as time goes on, and long chain segments of polymer molecules are mutually permeated, diffused and wound to form a uniform film with good performance;
at the stage, the polyether organic silicon defoaming agent can achieve a dispersing effect on the nano bauxite, so that the nano bauxite is fully blended into the water-based acrylic resin, crosslinking is increased among long chain segments of polymer molecules, a net structure is formed inside, the film forming strength is improved, meanwhile, the nano bauxite is distributed in the net structure, due to the high fire resistance of the nano bauxite, the heat transfer is effectively blocked, the melting point of a coating film is improved, and the effect of improving the fire resistance is achieved.
4. The thermal decomposition temperature of the flame retardant is more than 250 ℃, the thermal decomposition speed of the cured coating can be slowed down, and the carbonized layer is effectively prevented from cracking, so that the long-term fireproof performance can be ensured.

Test example 1
Test subjects: the aqueous fire-retardant wood finish paints of examples 1-4 and comparative examples 1-4 were prepared with the compositions shown in table 1 below (all units%).
TABLE 1
Test items: and (5) testing the drying property of the paint film.
The test basis is as follows: 1. the surface dry time is measured according to GB/T6753.2-1986 glass ball method for paint surface drying test; 2. the actual dry time is determined according to GB/T1728-1979 (1989) determination of the dry time of paint films and putty films.
And (3) testing results: see table 2.
TABLE 2
As can be seen from Table 2: when the volatile oil extracted from the water-soluble herbs in the formula components accounts for 0.5-2%, the surface drying acceleration effect is good; when the proportion of the volatile oil extracted from the water-soluble herbs is less than 0.5 percent, the effect of accelerating surface drying is obviously reduced, and the actual drying is not influenced; when the proportion of the volatile oil extracted from the water-soluble herbs is more than 2 percent, the effect of accelerating surface drying is better, but the actual drying is not facilitated; the surface drying speed is faster when the volatile oil extracted from the water-soluble herbs is replaced by ethanol, but the actual drying speed is reduced, so the proportion of the volatile oil extracted from the water-soluble herbs in the raw material formula is preferably 0.5-2%.
Test example 2
Test subjects: the aqueous fire-retardant wood finish paints of examples 1, 5 to 7 and comparative examples 5 to 7 were prepared with the compositions shown in the following table 3 (all units%).
TABLE 3
Test items: and (5) testing the drying property of the paint film.
The test basis is as follows: 1. the surface dry time is measured according to GB/T6753.2-1986 glass ball method for paint surface drying test; 2. the actual dry time is determined according to GB/T1728-1979 (1989) determination of the dry time of paint films and putty films.
And (3) testing results: see table 4.
TABLE 4
From table 4 it can be seen that: when the film forming auxiliary agent accounts for 1-4% of the components of the formula, the effect of accelerating the actual drying is good; when the film forming auxiliary agent accounts for less than 1 percent, the effect of accelerating the actual drying is obviously reduced, and the surface drying is not influenced; when the proportion of the film-forming additive is more than 4%, the effect of accelerating the actual drying is better, but the actual drying is too fast and is not matched with the surface drying speed, so that the surface of a dried formed paint film is wrinkled, and the attractiveness is influenced; therefore, the proportion of the film-forming aid in the raw material formula is preferably 1-4%.
Test example 3
Test subjects: the aqueous fire-retardant wood finish paints of examples 1, 8-11 and comparative examples 8-10 were prepared with the compositions shown in the following Table 5 (all units%).
TABLE 5
Test items: and (5) testing the fire resistance.
The test basis is as follows: the water-based fireproof wood paint finish obtained in the examples 1, 8-11 and the comparative examples 8-10 is respectively added with 12wt% of water, uniformly mixed and then coated on the surface of a wood board in a rolling way, and after the paint film is dried, corresponding tests are carried out according to the fire resistance detection indexes in the table 6 (the fuel for the combustion resistance test is industrial pure 100% ethanol).
TABLE 6
And (3) testing results: see table 7.
TABLE 7
As can be seen from Table 7: when the nano bauxite accounts for 10-25% and the flame retardant accounts for 10-20% in the formula components, the fireproof performance is good, and all detection indexes meet the first-class level; when the flame retardant accounts for less than 10% and the nano bauxite accounts for 10% -25%, the flame-resistant time data are obviously reduced, and the data of other detection items are negatively influenced; when the proportion of the flame retardant is more than 20 percent and the proportion of the nano bauxite is less than 10 percent, the flame-retardant time data obviously does not have an equal proportion growth trend along with the increase of the proportion of the flame retardant, but is negatively influenced by the reduction of other detection item data; when the flame retardant ratio is less than 10% and the nano bauxite ratio is more than 25%, the flame resistance time data is reduced obviously, and the negative influence on the data of other detection items is aggravated; therefore, the proportion of the nano bauxite in the raw material formula is preferably 10-25% and the proportion of the flame retardant in the raw material formula is preferably 10-20%.
The foregoing is a preferred embodiment of the present invention, and it should be noted that it would be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the principles of the invention, and such modifications and enhancements are also considered to be within the scope of the invention.
