Abstract
The invention discloses a novel protective agent for immersion type protection of a stone material and a preparation method thereof. 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.

Description
Technical field
The present invention relates to a kind of protective agent and compound method of novel stone material immersion type protection.
Background technology
The starting material that present ornamental stone material uses mainly are marble and grouan; Lithotome inside has all that quantity is various, the space of different sizes, and through capillary phenomenon, the pollutent of stone surface or bottom can be penetrated into stone material inside through these spaces; The water spots that formation is difficult to remove, Bai Hua, rusty stain and spot; In order to handle this problem, in recent years, in processing of stone industry, brought into use stone protectant.
Present stone protectant mainly is the organosilicon alkanes, and this is the osmosis type protective agent, and the principle of osmosis type protective agent is through solvent organism to be 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, and big multipotency and stone surface react; Form hydrophobic substance, didirtresistance is good, does not influence the ventilation property of stone material again; Can not make dirt be trapped in stone material inside; Reduced the probability of generation " pathology ", be convenient to clean, ageing-resistant, anti-ultraviolet property has had large increase, is to use the stone material Protection Product that increases gradually in recent years.
The stone surface of handling through organosilicon material, facade and domatic no matter, the globule all is difficult to stop, and during liquid water contact stone surface the globule is splashed, and produces similar effect on lotus leaf.
The technology of at present stone material being done protection be with hairbrush with the protective agent brushing on stone surface; But this technology has many shortcomings: the mode of this brushing protective agent often has the zone of gaps and omissions, such as the bottom surface that the stone material plate is placed, next; 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 influence protection effect and work-ing life so obviously.
So, in order to address this problem, and developed a kind of new method of doing protection---the immersion type protection,
Immersion type protection is for some time in the immersion protective liquid that slabstone is whole, makes the no gaps and omissions of protection, and saturated, this means of defence will use a large amount of protective liquids, requires protective liquid to have higher economical efficiency, and to the performance requriements of protective liquid also than higher.
Summary of the invention
The present invention addresses the above problem provides a kind of protection effect that can make stone material high protective agent with long service life, has guaranteed to protect no gaps and omissions, state of saturation.
For addressing the above problem, the present invention realizes through following scheme: a kind of protective agent and compound method of novel stone material immersion type protection, and the key step of its compound method is following,
Step 1, butyl triethoxyl silane and propenyl triethoxyl silane mixed in 1: 1 by volume, under 60 degrees centigrade temperature, kept 20 minutes, got solution A;
Step 2, chloroplatinic acid, dibutyl tin laurate and tosic acid mixed in 0.5: 1: 3.5 by volume, kept 40 minutes under 50 degrees centigrade the temperature, obtained solution B;
Step 3, solution A and solution B are dissolved in the absolute ethyl alcohol, fully stir, and under 50 degree celsius temperature, keep 30 minutes then;
The solution that obtains in step 4, the above-mentioned steps 3 adds an amount of water, just obtains described protective agent.
The composition and the volume ratio between the composition of above-mentioned protective agent are following,
Water 25%,
Absolute ethyl alcohol 30%,
Butyl triethoxyl silane 20%,
Propenyl triethoxyl silane 20%,
Tosic acid 3.5%,
Dibutyl tin laurate 1%,
Chloroplatinic acid 0.5%.
In the component content of said protective agent; Chloroplatinic acid; It is a kind of catalyzer that dibutyl tin laurate and tosic acid mixed the solution B that obtains in 0.5: 1: 3.5 by volume; Generate silane polymer in conjunction with butyl triethoxyl silane and the reaction of propenyl triethoxyl silane, said absolute ethyl alcohol is that hydrotropy is separated.
The stone protectant of the present invention's exploitation, its advantage: stone material is put into protective agent and is soaked, and makes the no gaps and omissions of protection, can reach capacity, and improves protection effect and increases the service life, and has higher economical efficiency and practicality.
Embodiment
Embodiment: get butyl triethoxyl silane and each 200ml of propenyl triethoxyl silane, pour in the vessel and mix, be placed under 60 degrees centigrade the temperature and kept 20 minutes, obtain solution A with volume; Get chloroplatinic acid 5ml again, dibutyl tin laurate 10ml and tosic acid 35ml put into another vessel, are placed under 50 degrees centigrade the temperature to keep 40 minutes again, obtain solution B; Again resulting solution A and solution B mixed dissolution in the absolute ethyl alcohol of 300ml, and fully stir, be placed on then under 50 degree celsius temperature and kept 30 minutes; Obtain solution C, in the gained solution C, put into 250ml water again, obtain said protective agent after fully stirring.
In process for preparation, the ratio of said protective agent is so following:
Water 25%,
Absolute ethyl alcohol 30%,
Butyl triethoxyl silane 20%,
Propenyl triethoxyl silane 20%,
Tosic acid 3.5%,
Dibutyl tin laurate 1%,
Chloroplatinic acid 0.5%.
The principle of protective agent:
Butyl triethoxyl silane, propenyl triethoxyl silane; Under the effect of catalyzer, can produce the polymer organosilicon polymer; Organosilicon material is to be determined by the chemical relationship between organosilicon material and the stone material inorganic materials in the protection on the stone material, because the chemical reaction between the two is prone to carry out.Stone product after organosilicon material is handled; Under given conditions; The silanol groups of stone surface and organosilicon molecular radical generation condensation dehydration reaction; Make the organosilicon molecular linkage be connected the stone product surface and also closely combine, be formed with the organic siloxane hydrophobic film, hydrophobic film is directed arrangement architecture.
Because alkyl is the hydrophobic group; So this organosilicon molecular linkage that aligns just has stronger hydrophobic nature; Stoped the wicking action of pore, and then stoped the people that advances of moisture content, and do not stopped up capillary gap for water; But simultaneously steam still can free permeation in siloxanes hydrophobic film district, thereby has guaranteed the ventilation property of stone material.
