Nano flame-retardant antistatic air duct cloth and preparation method thereof

Abstract

The invention discloses a nano flame-retardant antistatic air duct cloth and a preparation method thereof. The nano flame-retardant antistatic air duct cloth is prepared by dipping synthetic fibrous base cloth into PVC flame-retardant antistatic plasticizing paste containing a nano penetrating agent, flattening the synthetic fibrous base cloth by a flattening machine, heating and plasticizing thesynthetic fibrous base cloth in a drying oven to prepare a covering film with a flat and smooth surface, and cooling the covering film to obtain the nano flame-retardant antistatic air duct cloth. Theplasticizing paste completely permeates into the synthetic fibers, and the problem of air leakage of an air duct caused by easy falling and skin breaking of a covering film in the prior art is solved. Synthetic vegetable fatty acid ester with flame-retardant and antistatic properties and stone, ceramic tiles and artificial stone polishing slag with flame-retardant and smoke-suppressing propertiesare added into the formula, so that the problem that the flame-retardant property is weakened due to the addition of a large amount of a small molecular plasticizer in the prior art is solved. A large amount of polishing slag taken as an inorganic filler is added, the production cost is reduced, the flame retardant property and smoke suppressing performance of the product are improved, the problems that the polishing slag is difficult to recycle and environmental pollution is caused by waste landfill are solved, and waste is turned into resources.

Description

technical field [0001] The invention relates to the field of flame retardant materials for mines, and mainly relates to a nano flame retardant and antistatic air duct cloth and a preparation method thereof. Background technique [0002] Flame-retardant and anti-static air duct cloth is mainly used in the production of dust-proof ventilation ducts for mines, engineering tunnels, and underground construction. The prior art flame-retardant air duct cloth is made of glass fiber or synthetic fiber through weaving into a base cloth, which is mixed with PVC resin by adding plasticizer, antistatic agent, flame retardant and other raw materials, through extrusion, calendering, lamination, Cool to make. Glass fiber is brittle, has poor wear resistance, and is harmful to the human body if inhaled. Synthetic fibers and PVC calendered film have low bonding strength, and the covering film is easy to fall off and break after lamination, causing air leakage from the air duct and affecting...

AI Technical Summary

Problems solved by technology

The PVC flame retardant and antistatic plastisol of the present invention is added with a nano penetrant, and the extremely small particles can completely penetrate into the fiber gaps of the synthetic fiber base cloth, and are flattened by a flattening machine and heated and plasticized by a heating oven to form a surface. Flat and smooth cover film, the cover film and synthetic fiber base cloth are combined into one, which solves the problem of air leakage caused by the cover film falling off and broken skin in the prior art, with better confidentiality performance and longer service life
