Embodiment 1

[0078] Take by weighing 65kg of flame retardant chlorine (diisopropylamino) methoxyphosphine, 250kg of high molecular weight ammonium polyphosphate with a polymerization degree of more than 2000, and 150kg of composite phosphorus-containing flame retardant (wherein: methylphosphonic acid (5-ethyl -2-methyl-2-oxo-1,3,2-dioxaphosphorin-5-yl)methyl methyl ester 121.5kg, flame retardant FRC-1 (CAS No.42595-45- 9) 28.5kg), CelatomMW25 diatomite 100kg, acrylate adhesive 35kg, PEG4K polyethylene glycol 40kg, amino silicone oil 3kg, polyoxyethylene ether wetting agent 5kg, water 800kg. The above materials are dispersed into a milky white suspension through the high-speed rotating impeller on the high-speed disperser, and then added to the padding tank. There is a stirring device in the padding tank, which continuously stirs the added materials to avoid material sedimentation.

Embodiment 2

[0097] The Celatom MW25 diatomite in the above-mentioned Example 1 was replaced with hollow glass microspheres of the same amount, and the rest of the proportions remained unchanged. Stir quickly in the padding tank to prevent the glass beads from floating on the liquid surface and the solid flame retardant powder from settling.

[0098] The fabric was produced by the same process as in Example 1, and tested according to the ISO9150 standard, the number of molten droplets was 21.

Embodiment 3

[0100] The Celatom MW25 diatomaceous earth in the above-mentioned embodiment 1 was replaced with the same amount of mica powder, and the remaining proportions remained unchanged. Stir quickly in the padding tank to prevent the solid flame retardant powder from settling.

[0101] The fabric was produced by the same process as in Example 1, and tested according to the ISO9150 standard, the number of molten droplets was 16.

Abstract

The invention belongs to the technical field of labour insurance protective suit, and particularly relates to a biodegradable flame retardant protective suit fabric. Aiming at the deficiencies of theexisting aramid fiber flame retardant protective suit for nuclear industry that an aramid fiber fabric cannot be dissolved in water, more energy is consumed in incineration, more toxic and harmful substances are generated, and more combustion residue is caused, the following technical scheme is adopted: the biodegradable flame retardant protective suit fabric is prepared by performing after finishing padding on polyvinyl alcohol spunlace non-woven fabric, and an after finishing padding solution contains: chlorine (diisopropylamino) methoxy phosphine, high molecular weight ammonium polyphosphate, a flame retardant, kieselguhr, an acrylic ester binder, polyethylene glycol, amino silicone oil, polyoxyethylene ether wetting agent and water. The protective suit fabric has the following benefits: water solubleness, environment friendliness, high molten metal resistance, and good heat insulation property.

Description

technical field [0001] The invention belongs to the technical field of labor insurance protective clothing, and in particular relates to a biodegradable flame-retardant protective clothing fabric and a padding liquid. Background technique [0002] Special types of work such as welding and cutting are often used in the daily inspection and maintenance of nuclear power plants. Protective products are required for welding. The ISO11611 standard stipulates the safety protection performance that welding protective clothing should have. In the environment of the nuclear industry, the use of reusable protective products is not only expensive for decontamination, but also has cumbersome pipelines, and is prone to the risk of radioactive contamination due to unclean decontamination. It is recommended to use disposable products for internal protection products in the nuclear industry environment for high-demand safety precautions. [0003] Traditional electric welding work clothes, t...
