Description

The preparation method of insulating materials is taken in a kind of power equipment maintaining protection
Technical field
The invention belongs to power domain, it is related to the preparation method that insulating materials is taken in a kind of power equipment maintaining protection.
Background technology
For certain industries, insulating protection clothes are often used.Such as power equipment maintaining personnel are to outdoor electricity Line repairs, fire fighter is when scene of fire is puted out a fire to save life and property indoors, all to wear insulating protection clothes.It is existing Insulating protection takes in addition to most important insulation function, being generally also provided with fire-retardant, acid-proof, alkali prevention and other effects, but wearing ten Divide inconvenience.
Existing oiliness insulating varnished silk product generally uses natural silk, that is, silk fabric（Silk fabric, band, cloth）For ground, uniformly Ground be coated with oiliness insulating varnish, drying and be made.
The class of insulation of oiliness insulating varnished silk, mechanical performance, anti-mildew, moisture resistance, anti-chemistry are the items skills such as acid-fast alkali-proof performance Art index, by ground and coating both surface layer performance is independent and interaction is influenced and restriction.Therefore, the product oil of prior art Property insulating varnished silk due to using low mechanical performance and very poor anti-mildew, moisture resistance, the natural silk fabrics of chemical resistance as ground, So that it generally has significant deficiency below：Heatproof, anti-mildew, moisture resistance, chemical resistance are poor.In this way, the electricians such as motor, electric appliance There is higher environmental requirement in product（Such as heatproof）Thin layer liner insulation and wrapping insulation, prior art production insulating varnished silk Obviously not competent；And common insulation is then connected due to its low anti-mildew, moisture resistance, chemical resistance for the torrid zone, warm torrid areas Also clearly forbidden, such as China ministry standard JB/Z91-75《The selection of tropical electric product insulating materials》Just clearly advise It is fixed：" humid tropics electric product must not use the material of the classes hygroscopicity and fungus resistance difference such as cotton yarn, silk, paper, cardboard and bamboo ".
Invention content
The purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of not only to have superior isolation performance but also have The electric insulation fabric of excellent anti-mildew, moisture resistance, chemical resistance.
The technical scheme is that so realize：A kind of preparation side for the insulating materials that power equipment maintaining protection is taken Method, including：
1）Warping process technique
The insulating materials is polyester terephthalate fabric, including warp thread and weft yarn, and there is 15-30g/m2Matter It measures, its danier number of any one of warp thread and weft yarn in the polyester terephthalate fabric yarn is the stock of 90 or bigger Line, and it is coarser than another yarn, it is less than in other yarn strand unit lengths compared with the yarn density setting in rove strand unit length Yarn density；Polyester terephthalate silvalin is successively placed on warping creel, all yarns are glued after sequencing with adhesive tape, winding In warp beam, warp beam breadth 1300mm, warp beam winding tension 2500N, 40~50CN of single yarn tension in creel, warping speed 150m/min；
2）, sizing operation technique
Slurry formula：It is composed of the following components：Vinyl trichlorosilane, methylvinyldichlorosilane, Amino resin, Epoxy resin, cumyl peroxide, curing agent, film forming agent, filler, ferrochrome are black, cosolvent, radiate reinforcing agent and organic solvent Deng；Wherein, the dosage of the vinyl trichlorosilane relative to 100 parts by weight, the methylvinyldichlorosilane is 60-140 The dosage of parts by weight, the Amino resin is 40-66 parts by weight, and the dosage of the epoxy resin is 20-70 parts by weight, The dosage of the cumyl peroxide is 3-5 parts by weight, and the dosage of the organic solvent is 150-230 parts by weight, described solid The dosage of agent is 1-5 parts by weight, and the dosage of the film forming agent is 1-5 parts by weight, and the dosage of the filler is 10-15 weight Part, the black dosage of the ferrochrome is 8-12 parts by weight；The dosage of the cosolvent is 3-5 parts by weight；The heat dissipation reinforcing agent Dosage is 10-15 parts by weight；The organic solvent is the mixed solvent of the dimethylbenzene, toluene and the n-butanol that centainly match；It is described Curing agent is one kind or several in peroxidized t-butyl perbenzoate, dibenzoyl peroxide and cumyl peroxide Kind；The film forming agent is one or more of dimethyl silicone rubber, methyl vinyl silicone rubber and dimethyl silicone polymer； The filler is that mass ratio is 2:1 talcum and china clay mixture；
Four warp beams are successively placed on creel, row's hook read, expansion reed is by the excessively each deflector roll of yarn band, then is involved in sky axis On, winding tension 3200N when driving, cylinder exports tension 1500N, beam of a loom breadth 1530mm, sizing speed 80m/min；
3）Knitting process technique
Using air-jet loom weaving, the warp beam after slurry is gaited successively by plain weave, plugs in reed, upper axis, woven fabric, thread count is 10.3 × 13.2/cm；
4）Postprocessing working procedures
Pre- destarch uses electrical heating method to pre-process this cloth with the speed of about 80m/min；Smoldering thermal-insulating phase temperature 410 ± 5 DEG C, soaking time 36h；Surface treatment is with the speed coated with coupling agent of about 60m/min, through being carried out at a temperature of 220 DEG C Drying, trimming are batched, are examined and packaging process.
Preferably, the weight compared with rove strand unit length is 1.5-2.5 times of other yarn strands.
Preferably, it is described compared with rove strand be weft yarn.
The present invention as ground, therefore is obtained as a result of the polyester terephthalate fabric Jing Guo special braiding Practical function outstanding：
1, excellent insulation performance：Two grades can be improved in the class of insulation, reach B-class insulation, to be wanted in competent electric product Ask the thin layer insulation compared with high temperature tolerance energy and wrapping insulation.
2, excellent anti-mildew, moisture resistance, chemical resistance, the insulation being applicable in the extensive electrician's product of humid tropical zone Demand.
3, using polyester terephthalate fabric, product cost can be made to reduce by 20~40%.
4, polyester terephthalate fiber raw material source is wide, stable, reliable.
Crucially, weathering impregnated insulating paint of the present invention in dispensing by introducing 2:1 talcum and china clay mixture improves The weatherability of insulated paint；The adhesive force for improving subbing and base material by introducing Amino resin lotion in dispensing； The anticorrosive property and vapor-proof penetration of coating are improved by introducing heat dissipation reinforcing agent in dispensing.By adding two in coating Methyl silicone rubber, methyl vinyl silicone rubber and dimethyl silicone polymer make coating volatilization when being sintered film forming is left away to be produced Raw capillary effect can tense the gap of molten particles, and improve the thermal conductivity of insulated paint.
The advantage of the invention is that the preparation method is scientific and reasonable, simple and practicable, convenient to carry out, the insulation of acquisition is poly- to benzene Dicarboxylic acid esters fabric not only has good mechanical property, high temperature resistant also resistance to instead of existing common insulating fabrics Mill, heat conduction, asepsis environment-protecting, be more in line with current international environment tissue and country proposed " it is safe and healthy, energy saving, green, The requirement of environmental protection ".
