Description

Fire prevention gelling agent and preparation method thereof
Technical field
The present invention relates to gelling agent manufacture field, and in particular to one kind fire prevention gelling agent and preparation method thereof.
Background technology
Silicic acid sodium raw materials are easily purchased, cheap, prepare and easy to use, have a wide range of application, and do not burn, be pollution-free, The features such as temperature tolerance and good endurance, now it is widely used in fire-retardant heat-insulation material.But because of its water-fast difference, generally require modified It can use, and addition is less, influences its fire protecting performance.
Publication No. CN1269337A discloses a kind of modified crisis glass fiber reinforced fire-proof decoration door, wherein formula include it is aerobic Change magnesium, Lauxite, sodium metasilicate these three materials, but the content of its magnesia is up to 60%, and the content of sodium metasilicate is only Have 8.3%, this mainly reaches fire prevention using the back-fire relief effect of magnesia.It is and inorganic disclosed in Publication No. CN102167562A Fiberglass strengthens composite, the magnesia in this material is 45-65 parts, Lauxite 1.3-3.1 parts, sodium metasilicate 0.3-0.4 Part, used it can thus be seen that sodium metasilicate therein is also intended only as a small amount of addition, and preparation method is also simply simple mixed Close, be unable to reach the modification of sodium metasilicate.Publication No. CN105399435A discloses a kind of homogeneous fireproof heated board and its making Method, wherein fire resistant flame retardant inorganic material (magnesia, sodium metasilicate etc.) 95-110 parts, fire-resistant binding agent (Lauxite, Phenolic resin etc.) 50-70 parts, this is the improvement of inorganic material.But its preparation method is scattered for simple mixing, is unable to reach Modification to sodium metasilicate, therefore its water resistance is not still high, influences to use.
In summary, it is existing using sodium silicate inorganic material as the technology of fire proofing material in, sodium metasilicate amount largely be present The problems such as very little and modified insufficient, water resistance is bad, influence its purposes in fire proofing material.Therefore, a kind of environmental protection of exploitation The gelling agent that type fire prevention is water-fast is very urgent.
The content of the invention
In order to solve the above problems, the present invention proposes a kind of water-fast gelling agent and preparation method thereof of preventing fires.
To achieve these goals, the present invention is achieved through the following technical solutions:
One kind fire prevention gelling agent, including following components, by mass percentage for:Sodium metasilicate 45-65%, magnesia 15- 35%th, silicon phosphate 1-3%, organic material 5-20%, filler 0.5-5%.
Preferably, prevent fires gelling agent, including following components, by mass percentage for:Sodium metasilicate 50-65%, magnesia 20- 30%th, silicon phosphate 1-2%, organic material 5-15%, 0.5-3%.
Preferably, prevent fires gelling agent, including following components, by mass percentage for:Sodium metasilicate 60-65%, magnesia 25- 30%th, silicon phosphate 1.5-2%, organic material 8-10%, filler 0.5-2%.
Preferably, prevent fires gelling agent, including following components, by mass percentage for:Sodium metasilicate 62%, magnesia 26%, Silicon phosphate 1.5%, organic material 8.5%, filler 2%.
Preferably, the filler is any one in silicate, aluminate, aluminium sulfate, ferrous aluminate, phosphate It is or several.
Preferably, the organic material is the organic polymer containing carboxyl or hydroxyl.Such as polyvinyl alcohol, ethylene glycol, sweet One or more in oil, POLYPROPYLENE GLYCOL, 2,2- dihydromethyl propionic acids, carboxymethyl cellulose salt.
A kind of preparation method for gelling agent of preventing fires, comprises the following steps:
(1) sodium metasilicate, silicon phosphate are added to reactor, adds after water is sufficiently mixed and be gradually heating to 200-300 DEG C, after stirring 30-50min, stand, obtain mixture I;
(2) the mixture I that step (1) obtains is cooled to 100-120 DEG C, adds magnesia mixing, mixed Compound II;
(3) mixtures II in step (2) is cooled to 30-40 DEG C again, and adds organic material and filler, fully Mixing, is produced.
Preferably, the content of the water added described in step (1) is the 10-15% of sodium metasilicate by percentage to the quality.
Preferably, time of repose described in step (1) is 10-20min.
Preferably, mixing time described in step (2) is 30-40min.
Present invention fire prevention gelling agent and preparation method thereof, its advantage is:
(1) silicon phosphate is fully hydrolyzed out silicic acid, phosphate radical and hydrogen ion in the case of 200-300 DEG C, and in sodium metasilicate In sodium ion combined with cation, sodium ion is easily substituted by hydrogen ion under hydrionic attack, formed hydroxyl;And hydrogen The material that oxygen root is combined with silicate carries out autohemagglutination, forms silicic acid network structure.Include ammonium in the Lauxite added simultaneously Root and methylol, and ammonium root and methylol can be condensed with the hydroxyl in silicic acid group simultaneously, three kinds of materials form different Network structure is mutually passed, there is chain pole, also has the structure of pectination, can increase cohesive force, improves adhesive effect.Bubble is applied to during use On card or stalk board or common wood, material internal in plate material can be made to form vitreum, both combine together, greatly The big water-fast effect for improving sodium metasilicate and using.
(2) present invention is due to having used magnesia, sodium metasilicate etc. to have fireproof material, and fire protecting performance is good, in 800- 1000 DEG C of condition was not still burnt as a child persistently to fiery 4-6, and water resistance and intensity also do not change;Raw materials are Convenient source, and toxic and harmful gas will not be decomposed under the high temperature conditions, it is high-efficiency fireproof inorganic material, with existing inorganic material Material compares, and has significant effect.
