Abstract
The invention relates to a preparation method of a sludge flame-retardant material. The preparation method comprises steps as follows: 1) 6 parts of sludge, 1 part of benzene, methylbenzene and dimethylbenzene, 1 part of trichloro ethylene, 1 part of wood meal, 0.5 parts of zinc stearate, 1 part of calcium carbonate, 0.5 parts of maleic anhydride and 1 part of trimeric nitric amide are weighed and constitute a material A; 2) the material A is added to a beaker and stirred at the high speed, so that the components are evenly dispersed; 3) the beaker containing the material A in step 2) is placed on an electric furnace, and stirring and kneading are performed, so that the material A is evenly heated; 4) the material A is subjected to a polymerization reaction at the temperature of 200-300 DEG C, and the material A is quickly guided into a cavity of a mold when polymerized into a soft substance; 5) the mold is pressurized, and a finished product is prepared after molding and curing. The preparation method has the benefits as follows: 1) the cheap raw material, that is, the sludge, is used, so that the raw material cost is reduced; 2) the polymerization process is simple; 3) the polymeric material is free of pollution, and nitrogen and phosphorus flame retardants are added for enhancing the flame retardance; 4) smoke and poisonous gases are not produced during combustion.
Description
Technical field
The present invention relates to a kind of preparation method of mud fire retardant material, take mud as carrier, obtained pollution-free, the fire retardant material of low cost.
Background technology
Substantially locate in the same horizontal line with external advanced country at the flame-retarded technology of China, the difficulty of various fire-retardant product combustion require also be with reference to developed country similar standard stipulation out.But because China does not also have a comparatively complete fire-retardant Legal Norm at present, make the production of China's fire-retardant product and use still to lag far behind developed country.If the U.S. is in the nineties latter stage in last century, flame retardant plastics goods account for about 40% of the total usage quantity of its plastics, and meanwhile the fire-retardant product of China 1% does not all reach.
China superpolymer (various plastics comprise engineering plastics) fire-retardant in, mainly few based on consumption, flame retarding efficiency is high and the addition type bromide fire retardant of wide adaptability.In bromine system, polybromodiphenyl ether (PBD PO) can produce poisonous carcinogenic many bromos benzo alkane (PBDD) and many bromos cumarone (PBDF) when burning.And halogen flame generates a large amount of cigarettes and poisonous and acrid gas when burning, the corrosion that can cause Circuits System switch and other metal objects that can not be caused by fire merely and the critical defect that human respiratory tract and other organ are worked the mischief.Although so China's fire retardant material research aspect is relatively goodr, fire retardant material is applied in reality also very backward.
Summary of the invention
The present invention be directed to the deficiency that above-mentioned prior art exists, and the preparation method of a kind of low cost, free of contamination mud fire retardant material is provided.
The present invention solves the technical scheme that its technical problem adopts: a kind of preparation method of mud fire retardant material, comprises the following steps:
1) by mass fraction, take 5-7 part mud, 0.5-1.5 part triphen, 0.5-1.5 part trieline, 0.5-1.5 part wood powder, 0.3-0.8 part Zinic stearas, 0.5-1.5 part calcium carbonate, 0.3-0.8 part maleic anhydride, 0.5-1.5 part trimerization nitrogen ammonia, component material A;
2) by step 1) in the material A of gained add in beaker, high-speed stirring, makes component disperses even;
3) by step 2) in material A is housed beaker be placed on electric furnace, stir, mediate, material A is heated evenly;
4) material A is carried out polyreaction, temperature controls at 200 DEG C ~ 300 DEG C, when material A polymerization becomes software shape material, it is imported fast in mold cavity;
5) by mould pressurizing, the rear obtained finished product of shaping and solidification.
The fire retardant material using above aspect to obtain may be used for making fire-retardant flowerpot, flame-retardant panel material etc.
Compared with prior art, the invention has the beneficial effects as follows: the starting material 1) using this cheapness of mud, reduce raw materials cost; 2) polymerization process is simple; 3) polymeric material is pollution-free, adds nitrogen class and phosphorus type flame retardant enhancing flame retardant resistance; 4), during burning, cigarette and toxic gas is not produced.
Embodiment
