Abstract
The invention discloses a method for manufacturing an inorganic mineral paper rope, which has the following steps: first respectively crushing slag wool and waste paper by a crusher; adding 30 to 37% of water and 7 to 9.5% of waste paper scrap in a mixer, after mixing, adding 7 to 9.5% of MgO, 7 to 9.5% of Al2O3 and 15 to 19% of SiO2 to the mixer in turn, after stirring for 10 to 50 minutes, adding 25 to 30% of ethyl vinyl acetate ethylene copolymerized emulsion, then stirring for 10 to 50 minutes, preparing paper pulp; evenly mixing slag wool powder and the paper pulp in weight ratio of 1:1, and using a plastic extruding machine to prepare original yarn with the diameter of about 2 mm through heating, compressing, kneading and squeezing; keeping the heating temperature to be from 100 to 220 DEG C, and then manufacturing the original yarn into an inorganic mineral paper rope. The invention has scientific material selection and matching and simple and reasonable process. The inorganic mineral filler paper rope can be filled in a cable, increases load flow by about 10%, and reduces current loss in the cable.
Description
Technical field
The present invention relates to a kind of inorganic mineral paper rope, relate in particular to a kind of inorganic mineral paper rope that cable is filled that is used for, belong to the cable filler technical field.
Background technology
Electric power resource is the basis of national economy, is the bases of the normal operation of all electronic equipments, it be the means of livelihood also be the means of production.Along with electrical network begins to sunken cord into ground, the cable heat-dissipating space is narrow relatively in the ground, has also just limited with the circuit transmission capacity under the uiform section to a certain extent, and the circuit loss increases substantially, thereby cable is proposed higher requirement.The line loss of electrical network is inseparable with the transmission capacity of cable, and the transmission capacity of cable depends mainly on the difference of structural design and Material Used, and " filling " is that unique back of changing is to cable electrical property, the minimum link of influence.
The thermal resistance value of packing material is big more, and the external heat radiation of conductor wire core just has some setbacks more, the circumscribed edge that most heat can only be through mask tape and oversheath to around distribute, the effective section that distributes is narrow.With the core in cross section, when the amount of damming is identical, use thermal resistance value big its conductor temperature of packing material and jacket surface temperature all higher, the raising of temperature rise has limited the transmittability of cable, has increased the loss of rated current in cable.
Existing cable filler, like the rope made of hemp, glass fibre gasket for packing, fan-shaped packing, polypropylene mesh tear-strap, inorganic paper string etc., their thermal resistance value is all greater than 1 ℃/w.The effect of using is unsatisfactory, causes a large amount of losses, can not really satisfy the demand in market.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned cable filler, for meeting the need of market, provides a kind of thermal resistance value little, can reduce the manufacturing approach of the inorganic mineral paper rope of cable electricity damage.
The present invention is achieved in that the manufacturing approach of inorganic mineral paper rope, it is characterized in that comprising the steps:
The first step: mineral wool is ground into the mineral wool powder of particle diameter 0.5-3mm with pulverizer, waste paper is pulverized the waste paper scrap below the 1mm of footpath in flakes with pulverizer;
Second step: in mixer, adding percentage by weight earlier is 30-37% water, 7-9.5% waste paper scrap, stirs after 1-2 hour, and adding percentage by weight successively is that 7-9.5%MgO, percentage by weight are 7-9.5%Al
2O
3, percentage by weight is 15-19%SiO
2, stir after 10-50 minute, adding percentage by weight again is 25-30% vinyl acetate ethylene copolymerization emulsions, stirs once more 10-50 minute, processes paper pulp;
The 3rd step: with weight portion is that 1: 1 mineral wool powder and paper pulp mixes; The employing screw slenderness ratio is 34: 1 a extruding machine; Through heating, compress, integrate, extrude diameter is the 2-4mm raw yarn, describedly is heated to be the multistage heating in subregion from high to low, and temperature is 100-230 ℃;
The 4th step: adopt strand system machine strand to process inorganic mineral paper rope the raw yarn of extruding, through after the assay was approved, the packing warehouse-in.
Described subregion is multistage to be heated to be: a district 220-230 ℃, and two district 200-210 ℃, three district 150-160 ℃, four district 100-110 ℃;
Described pulverizer is a cintrifugal disintegrator.
Described waste paper is white industrial waste paper.
Described mixer is that adjustable speed, impeller are the mixer of machinable rotation.
Selection scientific mixing of the present invention, the technology advantages of simple.Inorganic mineral paper rope replaces traditional rock wool with mineral wool in the raw yarn pulling process, add MgO, Al
2O
3, SiO
2In mineral matter, successfully solved mineral and be difficult for adding and disperseing inhomogeneous these two big technological difficulties.Replaced traditional rock wool with mineral wool; Mineral wool have tension, thermal insulation, sound absorption, corrosion-resistant, do not fire and inexpensive, sharp characteristics such as useless; Simultaneously; Mineralogical composition in the inorganic mineral paper rope can keep the construction of cable stable in the inner calculus that forms of cable when meeting accident breaking out of fire, avoids alternate short circuit.The MgO through surface-active-treatment, the Al that in raw yarn, have added market purchasing
2O
3, SiO
2In mineral matter; Strengthen the compatibility at itself and mineral wool interface; Do not have dust from flying when inorganic mineral paper rope is filled in cable in the assurance, meet environment protection requirement, utilize the noninflammability of mineral matter to improve oxygen index (OI) and the flame retardant effect and the flame retardant rating thereof of inorganic mineral paper rope.The mineral matter molecular structure has special sponginess, makes an addition to the effect that can strengthen its heat absorption, heat radiation in the inorganic paper string, has reduced inorganic paper string thermal resistance value; The heat that makes conductor wire core more equably to around distribute; Reduce the temperature of conductor wire core, improved and appraised and decided current-carrying capacity, reduced line loss; Play energy-saving and cost-reducing effect, also prolonged the service life of cable insulation and sheath simultaneously.
This inorganic mineral paper rope is through experimental test, combustibility: oxygen index (OI) 100%; Calcination loss rate :≤22%; Moisture percentage :≤0.05%; Hinder hot: thermal resistance value≤1 ℃/w.Be filled in the cable current-carrying capacity that reality is improved cable, compare, make current-carrying capacity improve about 10%, reduced electric current loss in cable, improved the cost performance of cable with the cross section cable with existing stuffing.It is the desirable stuffing that a kind of electric wire is produced.
