Embodiment 1

[0065] Into a planetary mixer (capacity 25 liters), 250 wt. Next, slowly add 6 parts by weight of red phosphorus NOVAEXCEL140, ammonium polyphosphate TERRAJU-60 (manufactured by Susu Co., Ltd.) 30 parts by weight, phosphate ester TCP (manufactured by Daihachi Chemical Co., Ltd.) within 5 minutes , and ultraviolet absorber チヌビン 327 (manufactured by Chiba Gaigi Co.) 0.8 parts by weight, antioxidant Ilganox 1010 (manufactured by Chiba Gaigi Co.) 0.8 parts by weight, light stabilizer HALS (manufactured by Chiba Gaigi Co.) 1.0 parts by weight, titanium dioxide 1.0 parts by weight. Next, 10 parts by weight of isopropanol was added. After the addition, stir for an additional 20 minutes. Then, under reduced pressure and 5 mmHg pressure, vacuum degassing for 30 minutes to obtain a flame retardant for mesh with a viscosity of 2,850 cp (BM type viscometer, rotor V-6, 12 rpm, 25° C.). The flame retardant is loaded into a water bath, introduced through a yarn guide, and its total finene...

Embodiment 2

[0069] The ethylene-vinyl acetate copolymer V-200 in Example 1 was replaced by 200 parts by weight of ethylene-vinyl acetate copolymer S-752 (manufactured by Sumitomo Chemical Industries, Ltd., vinyl acetate content 90% by weight, solid content 50% by weight). Except that no isopropanol was added, the flame retardant with a viscosity of 1,530 cp was prepared as in Example 1. Multifilament fibers with a denier of 3,000 were used, and the nozzle of the sizing machine used 0.8 m / mφ for the first time, and 0.9 m / mφ for the second time to obtain a coated yarn with a fineness of 5,676 denier.

[0070] Except that the covering yarn was woven with 30 warp yarns / 10cm and 30 weft yarns / 10cm, the flame-retardant mesh was prepared as in Example 1.

[0071] The composition of the flame retardant is shown in Table 1, and the performance of the flame retardant mesh treated with the flame retardant is measured, and the measurement results are shown in Table 3.

Embodiment 3

[0073] Use 175 parts by weight of ethylene-vinyl acetate copolymer V-200 (manufactured by Mitsui Petrochemical Co., Ltd., vinyl acetate content 19% by weight, solid content 40% by weight), α-olefin copolymer A-100 (manufactured by Mitsui Petrochemical Co., Ltd. Co., Ltd., solid content 40% by weight) 75 parts by weight were substituted for the ethylene-vinyl acetate copolymer in Example 1, and other than that in Example 1, a flame-retardant mesh was prepared.

[0074] The composition of the flame retardant is shown in Table 1, and the performance of the flame retardant mesh treated with the flame retardant is measured, and the measurement results are shown in Table 3.

Abstract

The present invention provides a flame-retardant for anti-flaming mesh sheet which generates no halogen gas and has good gloss and flexibility without raising viscosity during the storage, and an anti-flaming mesh sheet making use thereof. Mesh sheet flame-retardant is so compounded that red phosphorus of 1.4-15 pts.wt., polyphosphoric acid ester ammonium compound of 10-50 pts.wt., and phosphate of 3-30 pts.wt. are compound with solid content 100 pts.wt. of ethylene vinyl acetate copolymer aqueous dispersion of vinyl acetate content 10-95 wt.% and resin solid content 25-75 wt.%, and it also includes a compound using Alpha-olefin copolymer aqueous dispersion or polyurethane aqueous dispersion.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant mesh that can be used in outdoor construction sites and civil engineering construction sites for a long time. Background technique [0002] In recent years, there has been a tendency in the construction industry to increase the number of high-rise buildings. On the other hand, low-level housing is also increasing. In this regard, the relevant parties have stipulated that in the on-site construction of the construction site, the construction unit is obliged to install flame-retardant mesh for safety protection, flame-retardant mesh for ground-floor residences, and flame-retardant mesh for preventing flying objects. The restrictions are getting stricter. [0003] The currently used flame retardant mesh and the flame retardant mesh to prevent flying objects are coated with multifilament fibers such as polyester, nylon and polypropylene with a polyvinyl chloride paste resin composition, and after he...
