Abstract
The invention offer a kind of organo material for fireroofing and its preparation method.. The percentage by weight of the organo material for fireroofing is that china clay is 40%-60%, paraffin is 20%-35% and assemble mmonium is 7%-15%. The bulgy copul, which percentage by weight is that carbamide is 20%-30%, formaldehyde is 65%-75% and ortho phosphoric is 4%-6%, is also used. The preparation method follows this, first, prepare the bulgy copul, second, prepare the organo material for fireroofing. Baneful chlorine hydride gas will not come out because of using chlorinated paraffin wax containing high chlorinity. Using the bulgy copul, the organo material for fireroofing will balloon up rapidly, so, the fire can not diffuse. In a word, the invention has a better effect of fire control.
Description
Technical field
The present invention relates to a kind of fire-retardant material, relate in particular to a kind of organic fire prevention plugging material and preparation method thereof.
Background technology
Fire-proof sealing material is a kind of various various openings that form when thing such as cable, airduct, oil pipe, tracheae etc. pass wall (storehouse) wall, building (first) plate and the fire-resisting division of cable testing bridge, materials of have fire-proof function, being convenient to change of running through of shutoff that are used for.Can be divided into inorganic fireproofing plugging, organic fire prevention calking and back-fire relief bag according to its moiety and performance characteristics.Organic fire prevention calking is because it has certain plasticity-and snappiness, and it is easy to use to construct, and is subjected to user's welcome deeply.The organic fire prevention calking of prior art generally is prepared from china clay, clorafin, silicone oil and chlorinated polyvinyl chloride.Because chlorinity height in its employed clorafin, once can emit deleterious hydrogen chloride gas when meeting fire burns, be detrimental to health, therefore its application is restricted, especially in some occasion, for example Nuclear power plants does not more allow to occur this situation.
Summary of the invention
The present invention discharges the problem of toxic gas and a kind of organic fire prevention plugging material of toxic gas and preparation method thereof that can not discharge when the burning is provided for the organic fire prevention calking that solves prior art exists when burning.
The technical measures that the present invention taked are: a kind of organic fire prevention plugging material is mixed with and is formed by china clay 40-60 weight part, paraffin 25-35 weight part, ammonium polyphosphate 7-15 weight part, swollen resin 7-15 weight part; Described swollen resin is prepared from by urea 20-30 weight part, formaldehyde 65-75 weight part, phosphatase 24-6 weight part.
The granularity of described china clay＞300 orders, water content＜2% (weight).
The softening temperature of described paraffin is at 30-40 ℃.
A kind of preparation method of above-mentioned organic fire prevention plugging material comprises following two steps:
Step 1, preparation swollen resin
In reactor, add the water that is equivalent to used weight of urea 1/2nd, add urea 20-30 weight part again, heat to 50-80 ℃, make the urea dissolving make urea soln, add formaldehyde 65-75 weight part and urea reaction then, keep 80 ℃ of reactions of temperature to reduce to room temperature after 20 minutes, add phosphatase 24-6 weight part again and mix, dewater the Precondensed UreaFormaldehyde Resin cured article, dry, pulverize the swollen resin finished product;
Step 2, preparation organic fire prevention plugging material
Add china clay 40-60 weight part, ammonium polyphosphate 7-15 weight part and the prepared swollen resin 7-15 of step 1 weight part earlier and stir in kneader, add paraffin 25-35 weight part then and stirred 20 minutes, discharging gets organic fire prevention plugging material finished product.
Organic fire prevention plugging material of the present invention has removed the high chlorinated paraffin of chlorinity in filling a prescription at it, thereby can not discharge deleterious hydrogen chloride gas when burning; Owing to adopted swollen resin, it is met can expand rapidly after fire is met heat, prevent intensity of a fire diffusion, thereby its flameproof effect is also better.
