Abstract
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
The present invention relates to a kind of compound method of stone material immersion type protective agent.
Background technology
The starting material that current ornamental stone material uses are mainly marble and grouan, lithotome inside all has that quantity is various, the space of different sizes, pass through capillary phenomenon, the pollutent of stone surface or bottom can be penetrated into stone material inside by these spaces, formation is difficult to water spots, Bai Hua, rusty stain and the spot removed, in order to process this problem, in recent years, in processing of stone industry, brought into use stone protectant.
Current stone protectant is mainly organosilicon alkanes, this is osmosis type protective agent, the principle of osmosis type protective agent is, by solvent, organism is penetrated into stone surface and deep layer, but do not stop up the pore of stone material, this type of protective agent adopts silicone based product mostly, large multipotency and stone surface react, form hydrophobic substance, didirtresistance is good, do not affect again the ventilation property of stone material, can not make dirt be trapped in stone material inside, reduce the probability of generation " pathology ", be convenient to clean, ageing-resistant, anti-ultraviolet property has had large increase, to use in recent years the stone protector product increasing gradually.
The stone surface of processing through organosilicon material, no matter facade and domatic, the globule is all difficult to stop, and when liquid water contact stone surface, the globule is splashed, and produces similar effect on lotus leaf.
At present to stone material do the technique of protecting be with hairbrush by protective agent brushing on stone surface, but this technique has many shortcomings: the mode of this brushing protective agent often has the region of gaps and omissions, such as the bottom surface of stone plate placement, secondly, manual operation always can not be perfect, have Lou the position of brush, and the mode of this brushing protective agent can not make stone protectant saturated, can affect so obviously protection effect and work-ing life.
So in order to address this problem, and developed a kind of new doing, the method for protecting---immersion type protects,
Immersion type protection is by for some time in immersion protective liquid whole slabstone, makes protection without gaps and omissions, and saturated, this means of defence will use a large amount of protective liquids, requires protective liquid to have higher economy, and also higher to the performance requriements of protective liquid.
Summary of the invention
The present invention addresses the above problem provides a kind of collocation method that can make the protection effect height of stone material and the protective agent of long service life, has guaranteed that protection is without gaps and omissions, state of saturation.
For addressing the above problem, the present invention realizes by following scheme: a kind of collocation method of stone material immersion type protective agent, and the key step of its collocation method is as follows,
Step 1, butyl triethoxyl silane and propenyl triethoxyl silane mix for 1: 1 by volume, keep 20 minutes at the temperature of 60 degrees Celsius, obtain solution A;
Step 2, chloroplatinic acid, dibutyl tin laurate and tosic acid mix for 0.5: 1: 3.5 by volume, keep 40 minutes at the temperature of 50 degrees Celsius, obtain solution B;
Step 3, solution A and solution B are dissolved in dehydrated alcohol, fully stir, and then under 50 degree celsius temperature, keep 30 minutes;
The solution obtaining in step 4, above-mentioned steps 3 adds appropriate water, just obtains described protective agent.
Volume ratio between composition and the composition of above-mentioned protective agent is as follows,
In the component content of described protective agent, chloroplatinic acid, the solution B that dibutyl tin laurate and tosic acid are mixed to get for 0.5: 1: 3.5 is by volume a kind of catalyzer, generate silane polymer in conjunction with butyl triethoxyl silane and the reaction of propenyl triethoxyl silane, described dehydrated alcohol is hydrotropy solution.
The stone protectant of the present invention's exploitation, its advantage: stone material is put into protective agent and soaked, makes protection without gaps and omissions, can reach capacity, and improves protection effect and increases the service life, and has higher economy and practicality.
Embodiment
Embodiment: get butyl triethoxyl silane and the each 200ml of propenyl triethoxyl silane of same volume, pour in vessel and mix, be placed at the temperature of 60 degrees Celsius and keep 20 minutes, obtain solution A; Get chloroplatinic acid 5ml, dibutyl tin laurate 10ml and tosic acid 35ml, put into another vessel again, then be placed at the temperature of 50 degrees Celsius and keep 40 minutes, obtains solution B; Again obtained solution A and solution B mixed dissolution in the dehydrated alcohol of 300ml, and fully stir, be then placed under 50 degree celsius temperature and keep 30 minutes; Obtain solution C, then put into 250ml water in gained solution C, after fully stirring, obtain described protective agent.
In layoutprocedure, under the ratio of described protective agent is like this:
The principle of protective agent:
Butyl triethoxyl silane, propenyl triethoxyl silane; under the effect of catalyzer, can produce the macromolecule organic silicon polymkeric substance; the protection of organosilicon material on stone material is to be determined by the chemical relationship between organosilicon material and stone material inorganic materials, because the chemical reaction between the two more easily carries out.Through organosilicon material stone product after treatment, under given conditions, the silanol groups of stone surface and organosilicon molecular radical generation condensation dehydration reaction, make organosilicon molecular linkage be connected to stone product surface and closely combine, be formed with organic siloxane hydrophobic film, hydrophobic film is directed arrangement architecture.
Because alkyl is hydrophobic group, so the organosilicon molecular linkage aligning this just has stronger hydrophobic nature, stop the wicking action of pore for water, and then stop moisture content enter people, and do not stop up capillary gap, but simultaneously steam still can free permeation in siloxanes hydrophobic film district, thereby guarantee the ventilation property of stone material.
