Abstract
The present invention relates to a rubber plastic type fire fighting hose. A lining made of rubber plastic has the characteristics that unit length weight is light, the present invention is light and convenient and has good ageing performance and wide range adapting to temperature during the use, particularly, low temperature performance is good, the rubber plastic type fire fighting hose is soft as usual under the environment of 40 DEG below zero and can be repaired, etc. The manufacture method of the fire fighting hose has the step that the rubber plastic melted by heating is directly extruded on a blank hose under the condition of extrusion force at certain temperature. The present invention has the characteristics of simple technology, few process steps, no need of vulcanization, short production period, little energy consumption, investment saving, etc. Product cost can be reduced, labour intensity is lightened, and production efficiency is enhanced.
Description
The present invention relates to a kind of fire-fighting water delivery pipe racks and manufacture method thereof.
Must use conduit pipe when fire-extinguisher water hose is given first aid to as fire-fighting, its skin is fibers material tubular shape fabrics such as terylene and polyester-cotton blend, and the pipe racks lining is the sulfuric horizon or the coating of anti-seep water, and requires to have certain withstand voltage, wear-resisting property.Existing fire-extinguisher water hose lining has rubber-type and latex type, and rubber-type water band is heavier because of the big unit weight of rubber proportion, and use, inconvenient operation, especially poor performance at low temperatures influence use because of rubber lining hardens under the environment of subzero 40 degree.Latex type water band ductility is poor.
The manufacture method of existing rubber-type fire-extinguisher water hose is: at first with terylene or the polyester-cotton blend material tubular base band of rounding that weaves on looms, and be cut into 20 meters long one.Next is that natural rubber is plasticated, and filters behind the slitting, adds vulcanzing agent after-ripening refining, and slitting is extruded into the tubular shape sebific duct with Rubber Extruder again, and sebific duct is cut into and the corresponding length of base band.Then, on the sulfuration platform, manually sebific duct is introduced in the base band, in sebific duct, led to steam and pressurized gas after the relative fixed, progressively heat up, pressurize and vulcanize, surplus water in the artificial thereafter discharge tube, after baking, aeration-drying.The manufacture method of existing latex type water band has: the base band is cut into 20 meters one, hang on the pylon of rice surplus in the of 20, utilize piston motion repeatedly up and down in base band pipe, make latex stick to base band pipe inside to form thin layer, vulcanize then, sulfuration process is with above-mentioned rubber-type water band.The manufacture method of existing rubber-type and latex type water band, many, the complex process of operation, the manufacture cycle is long.Especially need to vulcanize, cause that required plant area is big, investment is many, energy consumption is big, and the gas leak phenomenon that occurs when secondly being sulfuration can't be remedied, the natural resources deficiency, and raw material supply is limited, and labor intensity is big.
The purpose of this invention is to provide fire-extinguisher water hose that a kind of unit weight is light, cryogenic property is good, ductility is good and the manufacture method of directly squeezing attached lining thereof.
The technological scheme of finishing the work is: make the fire-extinguisher water hose lining with rubber-plastics material, its manufacture method is: the rubber and plastic that will heat and dissolve, under certain temperature condition, directly squeeze the base band outer tube layer that is attached to after preheating, cooling back flange.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the enlarged view of fire-extinguisher water hose cross section partial structurtes of the present invention;
Fig. 2 directly squeezes the outer field process schematic representation of attached base band for dissolving rubber and plastic, and is appointed as the specification digest accompanying drawing.
The embodiment of fire-extinguisher water hose of the present invention is by structure fabrication shown in Figure 1.Tubular shape base band (1) is with terylene and the polyester-cotton blend material system of weaving on looms.Lining (2) squeezes attached forming with rubber-plastics material, the rubber and plastic Main Ingredients and Appearance is butadiene and vinyl benzene, have the characteristic of rubber and plastics concurrently, the elasticity that has rubber under the normal temperature, can resemble again under the high temperature that dissolving the plastics flows becomes plastic material, at present, being mainly used in and making sole and vamp, secondly is the modifier as plastics and pitch.Rubber and plastic lining on every meter water band weighs 50～160 grams, and the water band diameter of present embodiment is 50 millimeters, and the rubber and plastic lining weight on every meter length is 80 grams.
The manufacture method of described invention fire-extinguisher water hose further specifies and is the tubular base band of the rounding that at first weaves on looms, and the base band is inserted on the tringle, and with the pulling equipment traction, hauling speed is that per minute enters the roasting chamber preheating for 1～2.5 meter, and roasting temperature is 150～170 ℃; Then, the base band enters die head (3), sees Fig. 2, and is enclosed within on the core rod (4), and the crowded enclosure temperature that squeezes attached mould is 190～250 ℃; Rubber and plastic dissolves through the heating equipment heating of extruder, and heating-up temperature is 190 ℃～250 ℃, 45 millimeters of extruder screw diameters, and per minute 7-20 changes.Enter the rubber and plastic that squeezes attached chamber (5) through clamp-oning mouth, under the effect of extruding force, dissolve rubber and plastic and squeezed the skin that is attached to base band (6).The traction pipe racks squeezes attached rubber layer simultaneously continuously.Be cut into Len req after the pipe racks cooling with rubber layer, then flange.Embodiment's base band baking preheating temperature is 160 ℃, and crowded enclosure temperature is 210 ℃, and base band hauling speed is 1.5 meters of per minutes, and the rubber and plastic extrusion temperature is 210 ℃, and with the pipe racks employing water-cooled of rubber layer, Duan Houtong pressurized air flange is cut in cooling.
It is light that fire-extinguisher water hose of the present invention has a unit weight, and light and handy during use, convenient, aging quality is good, the adaptive temperature wide ranges, and especially cryogenic property is good, and is soft as usual under the environment of subzero 40 degree, and can realize repairing.The manufacture method of described fire-extinguisher water hose is simple, and operation is few, need not sulfuration, and with short production cycle, less energy consumption is reduced investment outlay, and reduces product cost, reduces labor intensity, and enhances productivity.
