specific Embodiment 1

[0029] The manufacturing method of the ultra-high molecular weight polyethylene braided hose comprises the following steps:

[0030] (1) Preparation of fluorine-containing silicone modified polyurethane polymer:

[0031] Put polytetrahydrofuran diol and hydroxyl-terminated fluorine-containing polyester polysiloxane in a weight ratio of 4:1 into a stirring tank whose rotation speed is 600 rpm, and simultaneously add ethyl acetate and acetone with a volume ratio of 1:1. Mix the solvent, stir and react for 30 minutes at a temperature of 60°C, add 5% hexamethylene diisocyanate of the weight of the polytetrahydrofuran diol, dropwise add 0.5% of the total weight of the above-mentioned input material Dibutyltin dilaurate Catalyst, equilibrated reaction for 90 minutes to obtain fluorine-containing silicone modified polyurethane prepolymer;

[0032] Add dropwise 1,4-butanediol diacrylate dissolved in a mixed solvent of ethyl acetate and acetone at a volume ratio of 1:1 in the above-me...

Abstract

The invention discloses a novel ultra-high molecular weight polyethylene woven fire-fighting hose and a manufacturing method thereof. The novel ultra-high molecular weight polyethylene woven fire-fighting hose comprises a hose woven layer and a liner coating, wherein a fluorine-containing organic silicon modified polyethylene coating is arranged in the hose woven layer. The manufacturing method of the novel ultra-high molecular weight polyethylene woven fire-fighting hose comprises the steps that warp threads made from ultra-high molecular weight polyethylene filaments and weft threads made from ultra-high molecular weight polyethylene purely-spun staple fiber yarns are first woven into the cylindrical hose through a circular weaving machine, the outer surface of the obtained product is coated with the fluorine-containing organic silicon modified polyethylene coating by using a cylindrical woven bag plastic coating machine, heating is performed for curing after forming, and then the outer surface of the hose is turned inwards to serve as an inner surface by using a hose turning device. The novel ultra-high molecular weight polyethylene woven fire-fighting hose is ultra-light and explosion-proof, is resistant to abrasion, bending, ultrahigh pressure and corrosion and is easy to coil and long in service life.

Description

technical field [0001] The invention belongs to the application field of polymer materials, and relates to a novel ultra-high molecular weight polyethylene braided fire hose and a manufacturing method thereof. Background technique [0002] In recent years, large-scale cities and high-rise residential buildings in my country are a general development trend. There are more and more high-rise buildings and they are getting taller, so the requirements for fire hoses are becoming more and more stringent. The original fire hose used to convey water has low strength, is prone to damage during use, has a heavy weight per unit length, and has low working pressure. It cannot be supplied with high-pressure water source, and cannot meet the fire fighting requirements of high-rise buildings. [0003] Ultra-high molecular weight polyethylene fiber has the characteristics of high strength, corrosion resistance, light weight, and wear resistance. It is currently the commercial high-perform...
