Abstract
The invention discloses a preparation method for a methyl silanol potassium sodium waterproof agent, which comprises the following steps of: reacting methyl silicate with sodium hydroxide and potassium hydroxide under stirring until heat is released, and adding water with stirring until the mixed solution is transparent. Through the scheme, the pasty high-efficiency methyl silanol potassium sodium waterproof agent is prepared by the simple preparation method of the invention without heating and heat preservation, wherein the active ingredient content of the waterproof agent is high; only a small amount of waterproof agent is required to be added for the waterproofing of inorganic materials; and compared with the conventional products, the waterproof agent is more convenient to transport and use.
Description
Technical field
The present invention relates to a kind of methyl silanol potassium sodium water-resisting agent and preparation method thereof.
Background technology
Single methyl silicon sodium alcoholate or methyl silanol aqueous solutions of potassium (be called for short silicon water) concentration be higher than 30% o'clock unstable, therefore, be used for waterproof, moistureproof methyl silicon sodium alcoholate or methyl silanol potassium at present and can only be made into 30% the aqueous solution, effective ingredient is low.Simultaneously, the currently available products complex manufacturing technology, production material needs through the reaction kettle reacting by heating and be incubated several hours just can obtain finished product, and single methyl silicon sodium alcoholate or methyl silanol potassium aqueous products transportation cost are high, and waterproof, protection against the tide, impervious effect are bad.
Therefore, prior art awaits improving and development.
Summary of the invention
Problem to be solved by this invention is to provide that a kind of technology is simple, the methyl silanol potassium sodium water-resisting agent of high density.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following:
A kind of making method of methyl silanol potassium sodium water-resisting agent may further comprise the steps: methyl siliconic acid and sodium hydroxide, Pottasium Hydroxide stirring reaction to heat release, are added entry to transparence then under agitation condition.
The making method of described methyl silanol potassium sodium water-resisting agent, wherein, wherein the weight part of each component is: methyl siliconic acid 30～50, sodium hydroxide 8～16, Pottasium Hydroxide 4～12, water 4～12.
The making method of described methyl silanol potassium sodium water-resisting agent wherein, also comprises step: cooling.
A kind of methyl silanol potassium sodium water-resisting agent; It is a paste; Contain sodium methyl silicate and methyl siliconic acid potassium; Through methyl siliconic acid 30～50 weight parts and sodium hydroxide 8～16 weight parts, Pottasium Hydroxide 4～12 weight parts are reacted to heat release, add afterwards entry 4～12 weight part mixings, the cooling make.
Described methyl silanol potassium sodium water-resisting agent is used for the waterproof of inorganic materials.
Described methyl silanol potassium sodium water-resisting agent, wherein, said inorganic materials is a cement.
Adopt such scheme, the present invention need not heat tracing through simple manufacturing method; Made a kind of paste methyl silanol potassium sodium water-resisting agent; Wherein active constituent content is high, and the waterproof that is used for inorganic materials only need add amount seldom, and is easier to transport and use than existing products.
Embodiment
Below, further explain is done in preferred embodiment of the present invention.
The present invention can obtain the stable miscible body of high density paste methyl silanol potassium sodium with the mixing solutions reaction of methyl siliconic acid and sodium hydroxide, Pottasium Hydroxide, and the product effective ingredient is high, is convenient to transportation.Utilize solution heat and the acid-base reaction heat of sodium hydroxide, Pottasium Hydroxide to make during production just can to carry out in the reaction several minutes complete, without supplementary heating, naturally cooling can obtain stable paste product.
Concrete technical process is following:
Getting parts by weight and be 30～50 methyl siliconic acid and add in the retort, is 8～16 sodium hydroxide with parts by weight respectively and parts by weight are that 4～12 Pottasium Hydroxide adds in the jar again, rapidly with scoop with the uniform mixing of rolling of material in the jar; Treat that material begins to generate heat when steaming; The adding parts by weight are 4～12 water, stir material fast with stirring rod, become transparent aqua up to the material complete reaction; Then that hydrothermal solution is canned, just the paste finished product behind the hydrothermal solution naturally cooling.
Wherein, stirring means is not limit, can hand mixing, and also can use other mechanical systems to make the rapid mixing of raw material, reaction.
More specifically, can prepare raw material (weight part), prepare according to the method described above, obtain the finished product of paste according to following table:
| Embodiment/raw material | Methyl siliconic acid | Sodium hydroxide | Pottasium Hydroxide | Water |
| 1 | 40 | 12 | 8 | 8 |
| 2 | 30 | 15 | 4 | 6 |
| 3 | 50 | 16 | 10 | 12 |
| 4 | 35 | 10 | 12 | 4 |
| 5 | 45 | 8 | 12 | 10 |
The miscible body of paste methyl silanol potassium sodium that the present invention makes, concentration of active substance can be up to 90%, and product is stable, and manufacture craft is simple, and production unit is simple, does not have energy consumption in the production process, and production rate is fast, and output is big.
Product of the present invention can be used for the for example waterproof of cement of inorganic materials, particularly material of construction.During use, can directly when the cement mixing, mix, also can dilute the back and after theing cement solidifies, be sprayed at the surface.Compare with the silicon water water resistance of selling on the market; Test shows; In cement products, mix the miscible body of paste methyl silanol potassium sodium of cement weight 1%, its waterproof, moisture effect are equivalent in cement products, mix the silicon water of cement weight 10%, at the miscible body aqueous solution of paste methyl silanol potassium sodium of cement products outside surface spraying 2%; Its waterproof, moisture effect are equivalent to the silicon water in cement products surface spraying 4%, and every square metre of consumption is 1/10th of a silicon water consumption.
The methyl silanol potassium sodium solution infiltrates inorganic material particles and hole; Dehydration produces one deck hydrophobic nature alkyl sodium-potassium silicate molecular film with Carbon Dioxide in Air reaction back at the particle and the cavity surface of inorganic materials goods such as cement; Surface tension to water can stop inorganic materials suction, the moisture absorption layer by layer, and increases its impermeability to water.Test shows that the hydrophobic stability of alkyl sodium-potassium silicate molecular film is higher than single sodium alkylsiliconate molecular film or single alkyl potassium silicate molecular film far away.
The present invention can be applicable to fields such as material of construction, mainly solves suction, the moisture absorption problem of inorganic materials such as cement products.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
