Description
Technical Field
The invention relates to the technical field of artificial stone production, in particular to a long-acting antibacterial artificial stone and a preparation process thereof.
Background
In the existing artificial stone process, more than 90 percent of quartz stone filler, a small amount of polyester resin and other auxiliary agents for adjusting bonding, curing agents and the like are generally prepared into the artificial quartz stone under vacuum, high temperature and high pressure. However, at present, the artificial stone products have great hidden dangers to the health of people who use and contact the artificial stone products due to surface pollution and breeding bacteria, so that the research on the antibacterial and bactericidal performance of the artificial quartz stone is concerned widely, and the demand situation that antibacterial material products are more and more vigorous is presented.
The artificial stone in the existing market has a few antibacterial effects, but the antibacterial effect is very different, and the general defects are reflected in the following three aspects:
1. because the existing artificial marble generally only adopts nano silver as an antibacterial agent, in order to ensure that the whole antibacterial effect of the artificial stone is better and the antibacterial time is longer, a large amount of nano silver antibacterial agent can be added in the process of preparing the artificial stone, and the nano silver as the antibacterial agent has certain poisoning risk, especially the amount of the exudates is too large, and the health is also influenced by the excessive exudates of the human body contacted for a long time.
2. In the prior art, the reason that the adding amount of the nano silver antibacterial agent is increased when the nano silver is used for preparing the artificial stone is that the whole antibacterial effect of the prepared artificial stone is poor due to the fact that the existing nano silver antibacterial agent is poor in dispersity and difficult to move and fully mix when the existing nano silver antibacterial agent is added into the raw materials of the artificial stone.
3. In rostone practical application, often can assemble the rostone, and assemble the position and be exactly the position that the bacterium breeds most easily, consequently under the whole not good prerequisite of antibiotic effect of rostone, do not have the help on other antibiotic layers and also hardly let the antibiotic effect of rostone reach long-term.
Disclosure of Invention
Aiming at the defects, the invention aims to provide a preparation process of an effective antibacterial artificial stone, which has an antibacterial structure with better integrity and a long-acting antibacterial effect.
In order to achieve the purpose, the invention adopts the following technical scheme:
a preparation process of a long-acting antibacterial artificial stone comprises the following steps:
A. placing unsaturated polyester resin, modified organic silicon resin and organic nano silver antibacterial agent into a stirrer, keeping the temperature at 30-40 ℃, fully stirring and mixing to obtain mixed resin, and standing for 10-30 minutes to obtain the mixed resin;
B. adding the filler into the mixed resin, and stirring and fully mixing to obtain a filler mixture;
C. fully mixing the curing agent, the curing accelerator and the improver, and then pouring the mixture into a stirrer to be uniformly mixed with the filler mixture to obtain a standby mixture;
D. coating a surface layer antibacterial agent on the bottom and the peripheral side walls of a mold forming cavity, wherein the surface layer antibacterial agent comprises the following components in parts by weight: 0.1-0.5 part of nano titanium dioxide dispersion liquid, 5 parts of polyhydric alcohol, 5 parts of acid anhydride and 5 parts of guanidine hydrochloride; immediately pouring the standby mixture into a mold forming cavity, vibrating the mold until the top surface of the standby mixture is flat, and coating a surface antibacterial agent on the top surface of the standby mixture; preferably, the thickness of the surface layer antibacterial agent is 1-3MM, the too thin antibacterial effect is poor, the too thick antibacterial agent can be fused with the isolation adhesive layer too much, the protection and isolation effects of the isolation adhesive layer are weakened, and the thickness of the artificial stone surface layer antibacterial layer structure formed too thin is possibly damaged incompletely.
E. Sending the mixture after the material is evenly distributed into a press, vacuumizing to 0.08-0.1 MPa, flattening the material by vibration, removing the vacuum environment, and curing and forming at the temperature of 120-140 ℃ to obtain a semi-finished product;
F. coating isolation glue on the surface of the semi-finished product, air-drying at 40-60 ℃ to form an isolation layer, polishing and finish-machining the coating layer to obtain the artificial stone finished product.
Specifically, the preparation process of the organic nano silver antibacterial agent comprises the following steps:
a1. dissolving phenyl ortho-hydroxybenzoate and sulfated castor oil to obtain a first mixed solution;
a2. ethylene glycol and isopropanol were mixed in a molar ratio of 1: 1 mixing to obtain a solution; dissolving one of silver sulfate, silver fluoride and silver nitrate as a silver salt by using the solution to obtain a second mixed solution;
a3. mixing the first mixed solution and the second mixed solution, and then adding sulfide as a modifier to obtain a third mixed solution;
a4. reacting the third mixed solution at 80-120 ℃ to obtain a reaction product;
a5. and cooling the reaction product at the temperature below 15 ℃ to obtain the nano-silver antibacterial agent.
In the preparation of the organic nano silver antibacterial agent, sulfide is added to improve the organic nano silver antibacterial agent, so that the dispersibility of the organic nano silver is better.
Specifically, the preparation process of the surface antibacterial agent comprises the following steps:
b1. adding polyalcohol and acid anhydride into a reaction container with a condenser to react for 3-3.5 hours at the temperature of 120-130 ℃ to obtain a reactant;
b2. adding the reactant and guanidine hydrochloride into a reaction kettle provided with a condenser and a deamination device, gradually heating, and reacting for 2 hours at the temperature of 130 ℃ to obtain a standby mixed solution;
b3. and adding the mixed solution into a stirring barrel at the temperature of 120 ℃, atomizing and spraying the nano titanium dioxide dispersion solution into the mixed solution while stirring, and stirring the mixed solution for 30 minutes by the stirring barrel at the rotating speed of 120-180r/min after the nano titanium dioxide dispersion solution is completely added to obtain the surface antibacterial agent.
Specifically, the preparation process of the isolation adhesive comprises the following steps:
c1. mixing 0.5-1 part of 1, 2-propylene glycol, 4-8 parts of deionized water, 4-5 parts of a binder, 1-2 parts of polymethyl acrylate, 70-80 parts of polyvinyl acetate emulsion, 20-25 parts of cyanuric aldehyde resin, 5-10 parts of barite powder and 1-2 parts of aluminum silicate according to the weight part ratio, stirring for 30 minutes at normal temperature, and preserving heat for 5-10 minutes at 45-55 ℃ to obtain the isolating adhesive. The thickness of the isolation glue is 3-5mm, and too thin the isolation glue can not play a role in protection, and too thick the isolation glue can affect the antibacterial and bacteriostatic effects on the surface of the artificial stone.
More preferably, the sulfide is sodium hydrosulfide or thioacetamide.
