Comparative example 1
The process was essentially the same as in example 1, except that the raw materials for the production of the synthetic stone were devoid of microbial agents.
Comparative example 2
The process was essentially the same as in example 1, except that the starting materials for the production of the artificial stone were devoid of aid A.
Comparative example 3
The production process is basically the same as that of example 1, except that the raw materials for preparing the artificial stone lack the aid B and the aid C.
Comparative example 4
The process was essentially the same as in example 1, except that the starting materials for the production of the artificial stone were devoid of aid B.
Comparative example 5
The process was essentially the same as in example 1, except that the starting materials for the production of the artificial stone were devoid of aid C.
The artificial stone is prepared by adopting the processes of the examples 1-3 and the comparative examples 1-5, the compressive strength, the flexural strength, the water absorption, the linear expansion coefficient and the fragrance condition are detected, and the detection results are as follows:
TABLE 1 Standard index for artificial marble
Remarking: table 1 shows standard indexes of artificial marble in national standard GBT 35157-2017.
TABLE 2 Artificial stone test results of examples 1 to 3 and comparative examples 1 to 5
Remarking: the compressive strength, the flexural strength, the water absorption and the linear expansion coefficient are detected by adopting the national standard GBT 35157-once-used 2017; detecting fragrance at normal temperature; "-" means not detected.
As can be seen from tables 1 and 2: (1) as can be seen from the data of examples 1-3, the artificial stone prepared by the invention has a compressive strength of above 118.9, a flexural strength of above 21.3MPa, and a linear expansion coefficient of 2.2X 10-5℃-1In the following, the following description is given,the artificial stone has fragrance, lasts for more than 1008 days, wherein the compressive strength and the flexural strength are at least 32.1 percent and 77.5 percent higher than the compressive strength and the flexural strength of the standard indexes in the table 1, and the water absorption and the linear expansion coefficient meet the requirements of the standard indexes.
(2) From the fragrance profile of example 2 and comparative examples 1, 2, the absence of microbial preparation and adjuvant a is not conducive to the sustained fragrance retention of the synthetic stone, because: the microbial preparation is prepared by inoculating trehalose to acidophilic chlorella and bacillus subtilis and then centrifuging, and the microbial preparation is added into spice for modification, so that the spice can be fully dispersed in the artificial boulder; in addition, the artificial marble can keep the fragrance for a long time without dispersing under the synergistic cooperation of the ethyl maltol (the auxiliary agent A) with the fragrance increasing effect and the modified spice.
(3) From the compressive strength data of example 2 and comparative example 3, the effect values of compressive strength generated when the aid B and the aid C are used together can be calculated to be 126.1 to 82.5 to 43.6 (MPa); from the compressive strength data of example 2 and comparative example 4, the effect values of compressive strength generated by the aid B alone, 126.1 to 105.7 to 20.4(MPa), can be calculated; from the compressive strength data of example 2 and comparative example 5, the effect values of compressive strength generated by the aid C alone, 126.1-110.3-15.8 (MPa), can be calculated; by combining the data, the effect value of the compressive strength generated by the additive B and the additive C when the additives B and C are respectively used independently can be calculated to be 20.4+ 15.8-36.2 (MPa), in conclusion, the percentage (43.6-36.2) ÷ 36.2 × 100% >, which is more than 10% of the effect value of the compressive strength generated by the additive B and the additive C when the additives B and C are used together, is higher than the effect value of the compressive strength generated by the additive B and the additive C when the additives B and C are respectively used independently, and the value is more than 10%, which indicates that the additives B and C play a synergistic effect in preparing the artificial stone and synergistically improve the compressive strength. In the same way, the percentage (7.4-6.6) ÷ 6.6 × 100% ═ 12.1% > 10% of the improvement of the effect value of the flexural strength generated when the aid B and the aid C are used together can be calculated compared with the effect value of the flexural strength generated by superposition when the aid B and the aid C are used separately, and the value is greater than 10%, which indicates that the aid B and the aid C play a synergistic role in preparing the artificial stone and also synergistically improve the flexural strength. This is because: the auxiliary agent B consists of diethylenetriamine and triethylene tetramine according to the mass ratio of 2: 1; the auxiliary agent C is composed of triethylamine, triethanolamine and pyridine according to the mass ratio of 1.3:3: 1.5. The prepared assistant B has good curing effect and can cure resin, the assistant C has good promoting effect and can accelerate the curing effect of the assistant B and promote the curing of the resin, so that the compressive strength and the flexural strength of the artificial stone are synergistically improved under the mutual matching of the assistant B and the assistant C.
The artificial stone was prepared by the process of examples 1 to 3, and the antibacterial ratio was measured as follows:
TABLE 3 examples 1-3 antibacterial effectiveness of the Artificial stones
Remarking: the antibacterial rate is detected according to antibacterial property JC/T897-2014 of the antibacterial ceramic product.
As can be seen from table 3, the antibacterial rate of the artificial stone products prepared by the processes of examples 1 to 3 far exceeds the standard index of detection, and the products of the present invention have not only excellent antibacterial property but also durable antibacterial property, which may be: the antibacterial agent selected by the invention is nano titanium dioxide, has the effects of ultraviolet resistance and antibiosis, and is favorable for greatly reducing the production cost by selecting the nano titanium dioxide with lower price.
