Abstract
The invention discloses a fire hose with long service life. The fire hose comprises a hose blank and an inner-layer rubber coating and an outer-layer rubber coating which are arranged on the inner side and the outer side of the hose blank respectively. The inner-layer rubber coating and the outer-layer rubber coating are both polyurea elastomer coatings. Each polyurea elastomer coating comprises the following components by weight: 45%-50% of polyvinyl chloride (PVC)/ nitrile butadiene rubber (NBR) blending material, 20%-22% of polyvinyl chloride, 10%-12% of acrylic rubber, 1%-2% of light calcium carbonate, 4%-5% of antiager and 2%-4% of sulphur. The fire hose has good abrasion resistance and long service cycle. Safety performances such as abrasion resistance, bending resistance and high temperature resistance of the hose are greatly improved by means of the coatings applied to the fire hose. Due to the fact that the polyurea elastomer coatings are coated on the inner layer and the outer layer and components and contents of the coatings are standard and reasonable, the fire hose is high in adhesion strength, not easy to age and delaminate, high-temperature-resistant, corrosion-resistant, high-pressure-resistant, good in use performance and long in service life.
Description
Technical field
The present invention relates to a kind of fire-extinguisher water hose of long service life, belong to the fire-fighting equipment technical field.
Background technique
The fire extinguishing of the scene of fire too busy to get away fire-extinguisher water hose of speedily carrying out rescue work, existing fire-extinguisher water hose majority are that the internal surface at the fibrage layer increases one deck rubber lining, and this water band wear resistance is relatively poor, easily delamination behind the ageing of rubber, and bursting pressure is lower, and safety reliability is bad.
Innovative product is also arranged recently, increase rubberised layer at the outer surface of water band, but the component of the used material of this rubberised layer and content are lack of standardization, unreasonable, cause the performance such as withstand voltage, wear-resisting of this kind water band still undesirable, working life is not long yet.
Summary of the invention
At the deficiency that prior art exists, the object of the invention provides a kind of fire-extinguisher water hose of safe and reliable, long service life.
To achieve these goals, the present invention realizes by the following technical solutions:
The present invention includes made-up belt and the internal layer rubber-coated layer and the outer layer rubber coating layer that are arranged on made-up belt inboard and the outside, internal layer rubber-coated layer and outer layer rubber coating layer are polyurea elastomer coating; The component of polyurea elastomer coating and weight percentage are PVC/NBR blend composition 45%-50%; PVC 20%-22%; Acrylate rubber 10%-12%; Precipitated calcium carbonate 1%-2%; Age resister 4%-5%; Sulphur 2%-4%.
Above-mentioned made-up belt is made of warp and parallel braiding.
Above-mentioned warp adopts polyester thread, and described parallel adopts the polypropylene fibre line.It is low to have cost, advantages such as long service life.
The materials weight ratio of PVC and NBR is 1:2.4 to 1:2.8 in the above-mentioned PVC/NBR blend composition.
Water band of the present invention has good wear resistance, insulating properties and aging quality resistance and long life cycle, the coating layer that is applied to fire-extinguisher water hose can improve Safety performances such as the resistance to wearing of water band, counter-bending, high temperature resistance greatly, prolong the working life of water band, especially in the places such as glass window of water band through cement turning easy to wear, easy scuffing, can farthest protect the water band, avoid wearing and tearing, improve the working efficiency that fire-fighting is speedily carried out rescue work; The present invention is because internal and external layer all applies polyurea elastomer coating, and its component and content standard, reasonable, thereby the bond strength height, is difficult for aging delamination, can be high temperature resistant, corrosion-resistant, high pressure resistant, and usability is good, and the life-span is long.
