Comparative example 1
The production process is basically the same as that of example 2, except that polyvinyl chloride fibers, magnesium lignosulfonate and aqueous epoxy resin emulsion are absent in the raw materials for preparing the wood-grain-like inorganic artificial travertine.
Comparative example 2
The production process was substantially the same as that of example 2, except that polyvinyl chloride fibers were absent from the raw materials for preparing the wood grain-imitating inorganic artificial travertine.
Comparative example 3
The process was substantially the same as that of example 2, except that the raw material for producing the wood grain-like inorganic artificial travertine was deficient in magnesium lignosulfonate.
Comparative example 4

The production processes of examples 1-3 and comparative examples 1-4 are adopted to prepare the wood grain-imitated inorganic artificial travertine, the flexural strength, the compression strength and the combustion performance grade are detected, and the detection results are as follows:
remarking: the breaking strength is detected by adopting the national standard GB 35157 and 2017; the breaking strength is detected by adopting the national standard GB 35157 and 2017; the combustion performance grade is detected by using the national standard GB 8624-.
From the above table, it can be seen that:
(1) as can be seen from the indexes of the examples 1-3, the flexural strength of the wood-grain-like inorganic artificial travertine prepared by the invention is more than 9MPa, the compressive strength is more than 80.1MPa, and the combustion performance grade is A1, which shows that the wood-grain-like inorganic artificial travertine prepared by the production process of the invention has excellent performance; by combining the data indexes of examples 1-3, it can be seen that example 2 is the most preferred example.
(2) From the flexural strength data of example 2 and comparative example 1, the effect value of flexural strength generated when polyvinyl chloride fiber, magnesium lignosulfonate, and aqueous epoxy resin emulsion are used together is 9.6-5.7-3.9 (MPa); from the flexural strength data of example 2 and comparative example 2, the effect value of the flexural strength produced when the polyvinyl chloride fiber was used alone was 9.6 to 8.5 to 1.1 (MPa); from the flexural strength data of example 2 and comparative example 3, the effect value of the flexural strength produced when magnesium lignosulfonate was used alone was 9.6 to 8.8 to 0.8 (MPa); from the flexural strength data of example 2 and comparative example 4, the effect value of the flexural strength produced by the aqueous epoxy resin emulsion alone was calculated to be 9.6 to 8.3 to 1.3 (MPa); by combining the data, the effect value of the flexural strength generated by the polyvinyl chloride fiber, the magnesium lignosulfonate and the aqueous epoxy resin emulsion in a superimposed manner when the polyvinyl chloride fiber, the magnesium lignosulfonate and the aqueous epoxy resin emulsion are respectively and independently used is calculated to be 1.1+0.8+1.3 to 3.2(MPa), and in conclusion, the percentage (3.9-3.2) ÷ 3.2 × 100% >, which is more than 10% of the effect value of the flexural strength generated by the polyvinyl chloride fiber, the magnesium lignosulfonate and the aqueous epoxy resin emulsion in a superimposed manner when the polyvinyl chloride fiber, the magnesium lignosulfonate and the aqueous epoxy resin emulsion are respectively and independently used, is higher than the percentage (3.9-3.2) ÷ 3.2 × 100% >, which is higher than 10%, so that the polyvinyl chloride fiber, the magnesium lignosulfonate and the aqueous epoxy resin emulsion play a synergistic effect in the preparation of the wood grain-like inorganic artificial travertine and the flexural strength is synergistically improved. This is because: the polyvinyl chloride fibers are uniformly dispersed in various raw materials to form a staggered net structure, so that cracking is reduced, and the breaking strength of the wood-grain-like inorganic artificial travertine is enhanced; the magnesium lignosulfonate can be used for delaying the cement hydration time, reducing the heat release peak value and avoiding the concentrated formation of cracks by the heat release, thereby improving the breaking strength of the wood-like inorganic artificial travertine; the waterborne epoxy resin emulsion is filled in gaps of raw materials such as polyvinyl chloride fiber, magnesium lignosulfonate and the like, so that the bonding performance of the polyvinyl chloride fiber and the magnesium lignosulfonate is enhanced, and the function is better played.
