Description
Technical Field
The invention relates to the technical field of quartz stone plates, in particular to a quartz stone plate for a kitchen table board.
Background
The prior quartz stone plate has the advantages of rich colors, outstanding product performance, high hardness, scratch resistance, pollution resistance, low water absorption, low shrinkage and the like, and is widely used in industrial production and daily life as a decorative material for floor tiles, wall surfaces, window decks, kitchen table tops and the like. When the artificial quartz stone is used in places where the artificial quartz stone is in contact with food or in wet places, bacteria often grow on the surface of the artificial quartz stone. The common artificial quartz stone has no effect of inhibiting or killing bacteria.
Some existing antibacterial quartz stone plates are added with antibacterial ingredients, but the problems of large addition amount of the antibacterial ingredients, uneven dispersion, easy yellowing and aging of the quartz stone plates and the like still exist, the performance and the antibacterial effect of the plates are influenced, and the artificial quartz stone is unfavorable for use and popularization in the field of kitchens. Therefore, it is necessary to provide a quartz stone with good antibacterial and mildewproof effects and stable plate performance, so as to provide a guarantee for the health of users.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides an antibacterial and mildewproof quartz stone and a preparation method thereof. According to the invention, through scientific formula and optimized production process, the prepared quartz stone has excellent antibacterial effect and mildew-proof effect, and the plate has excellent physical properties.
One of the technical schemes adopted by the invention for solving the technical problems is as follows:
the antibacterial and mildewproof quartz stone comprises the following raw materials in parts by weight: 80-95 parts of quartz sand, 5-20 parts of unsaturated polyester resin, 0.08-0.2 part of curing agent, 0.1-0.5 part of coupling agent, 0.1-5 parts of pigment and 0.125-0.5 part of zirconium phosphate silver-zinc composite antibacterial agent; the particle size of the zirconium phosphate silver-zinc-loaded composite antibacterial agent is 400 meshes.
The particle size of 400 meshes means that the zirconium phosphate silver-zinc-loaded composite antibacterial agent is sieved by a 400-mesh sieve to obtain a part which can be sieved by the 400-mesh sieve for use, namely the maximum particle size of the zirconium phosphate silver-zinc-loaded composite antibacterial agent powder is about 38 mu m corresponding to the 400-mesh sieve. Similarly, the object of the present invention that the particle size is 10000 refers to that the zirconium phosphate silver-zinc composite antibacterial powder passes through 10000 meshes of sieve, i.e. the maximum particle size of the powder is about 1.3 μm corresponding to 10000 meshes of sieve.
The particle size of the zirconium phosphate silver-zinc-loaded composite antibacterial agent is 400 meshes. If the particle size of the antibacterial agent powder is too small, the antibacterial agent powder is difficult to disperse uniformly and is distributed unevenly in the quartz stone, so that the physical property and the antibacterial property of the quartz stone material are influenced; if the particle size of the antibacterial agent powder is too large, it is difficult to sufficiently exert antibacterial and antifungal activity.
In one embodiment, the particle size of the quartz sand is 40-100 meshes, that is, the maximum particle size of the quartz sand is about 150-420 μm corresponding to 40-100 meshes. The production cost can be reduced by selecting the raw materials of particles with the conventional particle size and quartz powder.
In one embodiment, the unsaturated polyester resin comprises at least one of an epoxy resin, a phenolic resin, an acrylic resin, or a polyurethane resin. The unsaturated polyester resin has excellent performance and flexible process performance, is used for adhering and curing the raw material quartz sand, and has good mechanical property after curing.

In the raw materials of the antibacterial and mildewproof quartz stone, quartz sand is solid particles or powder, and the zirconium phosphate silver-zinc-carrying composite antibacterial agent is solid powder; the unsaturated polyester resin, the curing agent and the coupling agent are liquid; the pigment may be solid or liquid. Zirconium phosphate carries silver-zinc composite antibacterial agent is solid powder, and the addition is less, if adopt traditional compounding mode, directly mix jointly with liquid components such as unsaturated polyester resin, curing agent, coupling agent, because these liquid components are mostly high molecular polymer, have certain stickness and quantity big, lead to zirconium phosphate to carry silver-zinc composite antibacterial agent to be difficult to the homodisperse, cause antibacterial agent to distribute inhomogeneous in the quartz, and antibacterial property is unstable. By adopting the mixing mode, the solid component and the liquid component are respectively mixed firstly, the zirconium phosphate silver-zinc-loaded composite antibacterial agent is uniformly mixed with the quartz sand which is solid, and the zirconium phosphate silver-zinc-loaded composite antibacterial agent is fully dispersed in the solid component mixing step; then the zirconium phosphate silver-loaded zinc composite antibacterial agent is mixed with liquid components such as unsaturated polyester resin, a curing agent, a coupling agent and the like which are uniformly mixed, so that the possibility that the zirconium phosphate silver-loaded zinc composite antibacterial agent is stuck by the unsaturated polyester resin and the like and is not easy to disperse is reduced, the problem that the antibacterial performance of quartz is unstable due to the fact that the antibacterial agent is not uniformly distributed is solved, and the obtained quartz has uniform antibacterial performance and good stability; and the mixing times are limited, and the process is simple.
When the pigment is solid, uniformly mixing the pigment, the zirconium phosphate silver-zinc-loaded composite antibacterial agent and the quartz sand to obtain a first mixture; and when the pigment is liquid, uniformly mixing the pigment with the unsaturated polyester resin, the curing agent and the coupling agent to obtain a second mixture. I.e. with a solid component if the pigment is solid and with a liquid component if the pigment is liquid, depending on the nature of the pigment used. It is best to adopt color paste and mix it with unsaturated polyester resin, curing agent, coupling agent and other liquid components.
Further, the mixing frequency is 15-55 Hz, and the mixing time is 3-10 min.
Further, the pressing condition is that under the vacuum condition of-0.1 Mpa, the vibration pressing is carried out for forming; the pressure is 50-200T (ton), the vibration frequency is 40-55 Hz, and the vibration time is 60-600 s.
Further, the curing conditions are that the curing temperature is 80-120 ℃ and the curing time is 60-90 min.
The equipment, reagents, processes, parameters and the like related to the invention are conventional equipment, reagents, processes, parameters and the like except for special description, and no embodiment is needed.
All ranges recited herein include all point values within the range.
In the present invention,% is mass% and ratio is mass ratio unless otherwise specified. The units of said mass are for example grams, kilograms or tons.
In the invention, the normal temperature can be 10-50 ℃, and the medium temperature can be 50-120 ℃.
Compared with the background technology, the technical scheme has the following advantages:
1. the zirconium phosphate silver-zinc-loaded composite antibacterial agent is of a porous structure, has a large specific surface area and strong adsorption capacity, can enhance the binding force between a carrier and metal ions, can effectively avoid the color change of silver, has good chemical stability, and is not easy to yellow quartz; and can generate a certain metal ion slow release effect, and the antibacterial and mildewproof capabilities are durable; and the porous structure can also play a role in removing odor and adsorbing organic matters. Under the condition that the addition proportion of the zirconium phosphate silver-zinc-loaded composite antibacterial agent is very low (for example, the addition proportion is 0.125%), the quartz stone has good antibacterial effect (the antibacterial rate is more than 99%) and mildew-proof effect, the cost is saved, and the physical performance of the quartz stone is not influenced.
2. The zirconium phosphate silver-zinc-loaded composite antibacterial agent can achieve good antibacterial and mildewproof effects under the condition of a low addition ratio, but the zirconium phosphate silver-zinc-loaded composite antibacterial agent is difficult to disperse uniformly due to the small addition amount. In order to solve the problems of uneven dispersion or agglomeration of the zirconium phosphate silver-zinc-loaded composite antibacterial agent, quartz sand, unsaturated polyester resin and the like and avoid the problems of white fog, granular sensation, easy color change, uneven antibacterial effect and the like on the surface of the produced quartz stone, the invention ensures that the zirconium phosphate silver-zinc-loaded composite antibacterial agent and the quartz sand are uniformly mixed by controlling the particle size of the zirconium phosphate silver-zinc-loaded composite antibacterial agent and changing the mixing mode in the preparation process, so that the prepared quartz stone has the advantages of uniform dispersion of all components, uniform distribution of antibacterial effect and high antibacterial overall performance, and is favorable for popularization in the field of kitchens.

The antibacterial and mildewproof quartz stone has good antibacterial and mildewproof performance and physical performance through detection.
Example 3: influence of particle size of zirconium phosphate silver-zinc-carrying composite antibacterial agent on dispersibility and antibacterial effect
The zirconium phosphate silver-zinc-loaded composite antibacterial agent with the particle size of 10000 meshes is selected, quartz stone is prepared according to the formula and the method in the example 1, and the antibacterial performance test is carried out according to activity determination of antibacterial agent doped in ASTM E2180-2018 polymeric or hydrophobic material.
Wherein the control sample is quartz without adding the zirconium phosphate silver-zinc composite antibacterial agent. "front", "middle" and "back" refer to parallel sampling locations on the quartz. The calculation formula of the antibacterial rate is as follows: the antibacterial ratio (%) - (the number of viable bacteria in the control sample-the number of viable bacteria in the antibacterial quartzite)/the number of viable bacteria in the control sample ] × 100%, the number of viable bacteria in the control sample is the number of viable bacteria after the bacteria culture on the control sample, and the number of viable bacteria in the antibacterial quartzite is the number of viable bacteria after the bacteria culture on the antibacterial quartzite. The results are shown in Table 3.
TABLE 3 antibacterial Properties of Quartz Crystal prepared with zirconium phosphate silver-zinc composite antibacterial agent of smaller particle size
As can be seen from Table 3, the parallel samples did not work well. The quartz stone prepared by the zirconium phosphate silver-zinc-loaded composite antibacterial agent with the grain diameter of 10000 meshes is explained to have uneven distribution of antibacterial powder and larger difference of antibacterial effects at different parts of the quartz stone.
The zirconium phosphate silver-zinc-loaded composite antibacterial agent with larger particle size and 400 meshes is selected, quartz stone is prepared according to the formula and the method in the example 1, and the antibacterial performance test is carried out according to activity determination of antibacterial agent doped in ASTM E2180-2018 polymeric or hydrophobic material. The results are shown in Table 4.
TABLE 4 antibacterial property of antibacterial mildewproof quartzite prepared with 400 mesh zirconium phosphate silver-zinc composite antibacterial agent
As can be seen from Table 4, the antibacterial properties of the parallel samples were uniform, and the antibacterial rate was not less than 99%. The quartz stone prepared by the zirconium phosphate silver-zinc-loaded composite antibacterial agent with the grain size of 400 meshes is explained to be uniform in distribution of the antibacterial agent, and the antibacterial effects of different parts of the quartz stone are basically kept consistent.
It can be seen from tables 3 and 4 that if the particle size of the zirconium phosphate silver-zinc-loaded composite antibacterial agent is too small, the zirconium phosphate silver-zinc-loaded composite antibacterial agent is difficult to disperse with quartz sand, and is obviously unevenly distributed in a quartz stone system, thereby affecting the physical properties and antibacterial properties of the quartz stone material. The zirconium phosphate silver-zinc-loaded composite antibacterial agent with about 400 meshes can solve the problems.
Example 4: effect of different preparation methods on dispersibility and antibacterial Effect
Under the condition of adding the zirconium phosphate silver-zinc-carrying composite antibacterial agent with the same proportion, preparing quartz stones by adopting different mixing sequences. Scheme 1 in this embodiment refers to the method of example 1 to prepare quartz stone, that is, the zirconium phosphate silver-zinc-loaded composite antibacterial agent is uniformly mixed with quartz sand, and then the mixture is mixed with the mixed unsaturated polyester resin, curing agent, coupling agent, color paste and the like to prepare the antibacterial and mildewproof quartz stone. In the embodiment 2, the zirconium phosphate silver-zinc-loaded composite antibacterial agent is mixed with the unsaturated polyester resin, the curing agent, the coupling agent, the color paste and other high polymer, and then mixed with the quartz sand to prepare the quartz stone.
According to the standard specification of JC/T897-2014 antibacterial ceramic product antibacterial performance appendix A antibacterial performance test method, the antibacterial effect of the scheme 1 and the scheme 2 on common infectious bacteria (such as escherichia coli and staphylococcus aureus) is quantitatively tested. Wherein, the calculation formula of the antibacterial rate is as follows: the antibacterial ratio (%) - (the number of viable bacteria in the control sample-the number of viable bacteria in the antibacterial quartzite)/the number of viable bacteria in the control sample ] × 100%, the number of viable bacteria in the control sample is the number of viable bacteria after the bacteria culture on the control sample, and the number of viable bacteria in the antibacterial quartzite is the number of viable bacteria after the bacteria culture on the antibacterial quartzite. The control sample is quartz without adding zirconium phosphate silver-zinc composite antibacterial agent. The results are shown in Table 5.
TABLE 5 antimicrobial Properties of Quartz Stone prepared under different compounding sequences
As can be seen from table 5, the antibacterial and mildewproof quartz stone prepared by the method of scheme 1 has uniform antibacterial performance and good stability, and solves the problem of uniform dispersibility, thereby ensuring the antibacterial effect. The quartz stone prepared by the method in the scheme 2 has unstable antibacterial performance, and the analysis probably causes that the antibacterial activity factors are not transferred to the surface of the quartz stone in time, so that the antibacterial rate is reduced.
By adopting other mixing methods (such as mixing all raw materials simultaneously and the like), the prepared quartz stone still has the similar problems of unstable antibacterial performance and poor dispersibility.
Example 5: influence of different antibacterial agents on antibacterial and mildewproof effects and physical properties of plates
The antibacterial and mildewproof quartz stone was prepared according to the method of example 1, and the proportions of the zirconium phosphate silver-zinc composite antibacterial agent were 0.125%, 0.25%, and 0.5%, respectively.

TABLE 11 anti-yellowing test results of Quartz Crystal prepared from silver-loaded Zeolite powder
It can be seen from tables 9 to 11 that the silver-loaded zeolite antibacterial powder has a high addition ratio to achieve a good antibacterial effect, and also causes the problems of unqualified aging resistance of quartz stone and the like.
For comparison, referring to the method of example 1 for preparing quartz stone, the zirconium phosphate silver-loaded zinc composite antibacterial agent was replaced with zinc-based antibacterial powder (pure nano zinc oxide) in the proportions of 0.125%, 0.5%, and 1.5%, respectively, and antibacterial tests were performed, with the results shown in table 12.
TABLE 12 antibacterial property of Quartz with Zinc-based antibacterial powder
As is clear from Table 12, the zinc-based antibacterial powder was added at a high ratio to achieve a certain antibacterial effect. And the pure zinc antibacterial powder is easy to agglomerate, and easily causes the problems of uneven dispersion and the like.
The results show that the zirconium phosphate silver-loaded zinc composite antibacterial agent is adopted when the artificial quartz stone is prepared, and compared with the zeolite silver-loaded antibacterial powder and the zinc-based antibacterial powder of pure nano zinc oxide, the zirconium phosphate silver-loaded zinc composite antibacterial agent has the advantages of low addition proportion, obvious antibacterial effect, excellent mildew-proof effect, and the mildew-proof grade reaching 0, and simultaneously ensures that the antibacterial mildew-proof quartz stone has excellent other physical properties.
