Description
Technical Field
The invention relates to the field of mine flame-retardant materials, and mainly relates to a nanometer flame-retardant anti-static air duct cloth and a preparation method thereof.
Background
The flame-retardant antistatic air duct cloth is mainly used for producing dustproof ventilation air ducts of mines, engineering tunnels and underground construction. The flame-retardant air duct cloth in the prior art is made by weaving glass fiber or synthetic fiber into base cloth, adding plasticizer, antistatic agent, flame retardant and other raw materials into PVC resin, mixing, extruding, rolling, fitting and cooling. Glass fibers are brittle, have poor abrasion resistance, and are harmful to human bodies when inhaled. The bonding strength of the synthetic fiber and the PVC calendering film is low, and the covering film is easy to fall off and break the skin after being attached, so that air leakage of the air duct is caused, and the service life of the air duct is influenced. PVC has high chlorine content and good flame retardance, but the addition of flammable plasticizer reduces the flame retardance of the material, so that the addition of expensive flame retardant is increased to meet the flame retardance requirement of mine use, and the production cost is high. The plasticizer in the PVC formula mainly takes phthalic acid plasticizers such as DOP, DBP and the like as main materials, and the plasticizer has high toxicity and is easy to extract, and related products are forbidden to be imported in Europe.
Therefore, the prior art is in need of improvement.
Disclosure of Invention
In view of the defects of the prior art, the invention aims to provide a nanometer flame-retardant antistatic air duct fabric and a preparation method thereof. The environment-friendly nano flame-retardant antistatic air duct cloth is prepared by dipping synthetic fiber base cloth into PVC flame-retardant antistatic plastisol, flattening by a two-roll flattening machine, heating and plasticizing by an oven and cooling. The PVC flame-retardant antistatic plastisol disclosed by the invention is added with a nano penetrating agent, tiny particles can completely penetrate into fiber gaps of synthetic fiber base cloth, a covering film with a smooth and flat surface is prepared by flattening by a flattening machine and heating and plasticizing by a heating oven, and the covering film and the synthetic fiber base cloth are combined into a whole, so that the problem of air leakage of an air duct caused by falling off and skin breaking of the covering film in the prior art is solved, the confidentiality is better, the service life is longerLong. According to the PVC flame-retardant antistatic plastisol, the synthetic vegetable fatty acid ester with flame-retardant and antistatic properties and the stone, tile and artificial stone polishing residues with flame-retardant and smoke-suppression properties are added into the formula at the same time, and the two are matched for use, so that the PVC flame-retardant antistatic plastisol has a good synergistic flame-retardant effect, replaces phthalic acid plasticizers such as DOP, DBP and the like which have high toxicity and are easy to extract and expensive flame retardants in the prior art, can reduce the production cost, and simultaneously provides an environment-friendly new product with better performance. The synthetic plant fatty acid ester is extracted from various plants, has the characteristics of no toxicity, environmental protection, oil bleeding inhibition, high plasticizing efficiency, long thermal stability time and the like, can absorb a large amount of oxygen when heated, and is oxidized and decomposed into CO2And H2O, has good flame retardance. The synthetic vegetable fatty acid ester is used for replacing the micromolecule plasticizer in the prior art, so that the problem of flame retardant performance reduction caused by the reduction of chlorine content of the product due to the addition of a large amount of plasticizer is solved. An antistatic agent is added in the process of synthesizing the vegetable fatty acid ester, and the synthesized vegetable fatty acid ester is added into the PVC flame-retardant antistatic plastisol for preparing the flame-retardant air duct cloth, so that the flame-retardant air duct cloth has permanent antistatic property.
The polishing slag is an industrial waste, is a large amount of waste slag generated by a series of procedures such as grinding, polishing and the like in the surface polishing process of stone, ceramic tiles and artificial stones, and has no toxicity. The main components are about 70 percent of polishing fine powder and about 30 percent of abrasive dust, and the polishing abrasive dust is composed of magnesium oxychloride cement binder accounting for about 10 percent of polishing slag and about 20 percent of Al2O3And SiC, wherein the magnesium oxychloride cement binder mainly comprises materials such as magnesium oxide, magnesium hydroxide, magnesium chloride hexahydrate and the like. PVC air duct cloth burns on flame and can be degraded to release HCI and CO2CO, toluene, etc., with the largest amount being HCI gas. Reacting magnesium oxide with HCI to generate magnesium chloride and water; reacting magnesium hydroxide with HCI to generate magnesium chloride and water; heating magnesium chloride hexahydrate in HCI airflow to react to generate magnesium chloride and water; HCI is dissolved in water to generate hydrochloric acid, and aluminum oxide reacts with the hydrochloric acid to generate aluminum chloride and water. Thus, the magnesium oxide in the polishing abrasive dustThe materials such as magnesium hydroxide and magnesium chloride hexahydrate are degraded during combustion to release HCI for reaction to generate chloride and water, and the flame retardant and smoke suppression performance is achieved. SiO in polishing fines295% of powder, these SiO being incombustible and resistant to pyrolysis2The powder forms a carbonization layer on the surface of the PVC air duct cloth during combustion, and the generation of the carbonization layer prevents heat and oxygen from entering and toxic gas from escaping, thereby improving the flame resistance of the PVC air duct cloth. The polishing slag is filled in the plastisol of the flame-retardant and anti-static PVC air duct cloth, oxides and chlorides in the polishing slag firstly react with HCI gas released by the combustion of the PVC air duct cloth to generate metal chlorides and water, and then a series of reactions are carried out to further exert the flame-retardant and smoke-suppressing performances of the polishing slag. It can be seen that the polishing slag is a composite flame retardant with multiple flame retardant mechanisms.
According to the nano flame-retardant antistatic PVC air duct fabric, the synthetic vegetable fatty acid ester with flame retardance and the polishing residues with flame retardance and smoke suppression are added in the formula, and the synthetic vegetable fatty acid ester with flame retardance and the polishing residues with flame retardance and smoke suppression are used cooperatively to generate better flame-retardant and smoke suppression effects. Solves the problem of the prior art that the chlorine content of the product is reduced and the flame retardant property is reduced due to the addition of a large amount of micromolecule plasticizer. The stone, the ceramic tile and the artificial stone polishing slag are added as inorganic fillers in a large amount, so that the production cost is reduced, the flame retardance and the smoke suppression performance of the product are improved, the problems that the stone, the ceramic tile and the artificial stone polishing slag are difficult to recycle and the waste landfill causes environmental pollution are solved, and waste is changed into valuable.
