Problems solved by technology
[0005] At present, the process of protecting stone is to use a brush to apply the protective agent on the surface of the stone, but this process has many disadvantages: this method of applying the protective agent often has missing areas, such as the bottom surface where the stone board is placed, and secondly , manual operation can never be perfect, there will be parts that are missed, and this method of applying protective agent cannot saturate the stone protective agent, which will obviously affect the protective effect and service life

Embodiment
[0018] Example: Take 200ml of butyltriethoxysilane and propenyltriethoxysilane of the same volume, pour them into a container and mix them, and keep them at a temperature of 60 degrees Celsius for 20 minutes to obtain solution A; then take hexachloro Put 5ml of platinum acid, 10ml of dibutyltin dilaurate and 35ml of p-toluenesulfonic acid into another vessel, and keep it at 50 degrees Celsius for 40 minutes to obtain solution B; then mix the obtained solution A and solution B Mix and dissolve in 300ml of absolute ethanol, stir well, and then keep it at 50 degrees Celsius for 30 minutes; obtain solution C, then put 250ml of water into the obtained solution C, and stir well to obtain the protective agent.
[0019] During configuration, the ratio of the protective agent is as follows:

The invention discloses a preparation method for immersion type protection of a stone material. The preparation method comprises the following steps: mixing butyl-triethoxysilane and allyl-triethoxysilane according to a volume ratio of 1: 1 and maintaining an obtained mixture at a temperature of 60 DEG C for 20 min so as to obtain a solution A (with a volume accounting for 40% of a total solution); mixing hexachloroplatinic acid, dibutyltin dilaurate and p-toluenesulfonic acid according to a volume ratio of 0.5: 1: 3.5 and maintaining an obtained mixture at a temperature of 50 DEG C for 40 min so as to obtain a solution B (with a volume accounting for 5% of the total solution); dissolving the solution A and the solution B in absolute alcohol (with a volume accounting for 30% of the total solution), carrying out full stirring and maintaining an obtained mixture at a temperature of 50 DEG C for 30 min; and adding a proper amount of water (with a volume accounting for 25% of the total solution) into a finally-obtained solution. The protective agent provided in the invention enables comprehensive and saturated protection to be realized, protection effects to be improved and a service life to be prolonged and has high economical efficiency and practicality.
Description
technical field [0001] The invention relates to a preparation method of a stone soaking protective agent. Background technique [0002] At present, the raw materials used for decorative stone are mainly marble and granite. Natural stones have a large number of voids of various sizes. Through capillary phenomena, pollutants on the surface or bottom of the stone can penetrate into the interior of the stone through these voids, forming a difficult Remove water spots, white blooms, rust and stains. In order to deal with this problem, stone protective agents have been used in the stone processing industry in recent years. [0003] The current stone protective agents are mainly organosilanes, which are penetrating protective agents. The principle of penetrating protective agents is to penetrate organic matter into the surface and deep layers of stone through solvents, but do not block the capillary pores of stone. Most of these protective agents use Most of the silicone products ...
