Abstract
An integral molding epoxy glass fiber laminating insulation joint gasket manufacturing process relates to the improvement of an epoxy glass fiber laminating cloth plate manufacturing process; the method comprises the following steps: 1) manufacturing a mould: 2) shearing the fibers of each layer; 3) coating a release agent; 4) laying each layer of fiber in a mould: 5) mixing epoxy resin and curing agent and degassing: 6) injecting glue: 7) pressure forming and curing: the advantages are that: because the mold is adopted for forming, if the size of the gasket can be ensured by the size of the mold, the gasket does not need to be lapped; because the degassing process is adopted, the micro air gap of the final product is reduced; the requirements of electrical insulation, mechanical strength, surface form and position tolerance and leakage resistance are met.
Description
Technical field:
The invention relates to the improvement of epoxy glass fiber lamination insulating joint pad manufacturing process.
Background technology:
Common lamination epoxy glass fiber fabric swatch (as 3240 epoxy glass fiber fabric swatch) manufacturing process, the fabric swatch of making is 1200 * 2000mm, utilizing the fabric swatch of this specification to make packing ring class part needs machining and packing to handle, the complex procedures of handling, the cost height, greater than 1200mm,, cause the requirement that to satisfy electric insulating quality, mechanical strength, surperficial form and position tolerance and anti-leakage property at overlapping part for the packing ring diameter because the restriction of the plate width of cloth needs overlap joint; Common lamination epoxy glass fiber lamination fabric swatch manufacturing process adopts traditional pre-impregnating process production, contain a large amount of little air gaps in the material, the impervious reduction under the high pressure operating mode produces seal failure owing to above reason makes product when the water pressure test, and insulating washer has also been lost insulation.
Summary of the invention:
The purpose of the invention provides a kind of process for manufacturing integral molding epoxy glass fibre laminated insulating joint pad that improves electric insulating quality, mechanical strength, surperficial form and position tolerance and anti-leakage; The purpose of the invention is to realize by following technical scheme:
Process for manufacturing integral molding epoxy glass fibre laminated insulating joint pad, its step is as follows:
1), mfg. moulding die: mould is made of positioning guide column, patrix, middle mould, counterdie, on middle mould upper surface, be shaped on resin overflow launder, exhaust hole and resin injection paths, positioning guide column is installed in the mesopore of counterdie, middle mould is installed on the counterdie, patrix is installed on middle mould and the positioning guide column;
2), shear each layer fiber: press the dies cavity size and shear;
3), coating release agent: adopt polyvinyl alcohol and silica gel oil, when mould is warming up to 100～120 ℃, on mould inner surface, be coated with polyvinyl alcohol twice, after the drying, be coated with last layer silica gel oil again;
4), at each layer of mould middle berth fiber: shop layer order: A, thickness 0.3mm surface, shop felt are 5 layers from lower to upper; 1 layer on B, shop thickness 0.2mm continuous fiber felt; 1 layer of C, the cotton-shaped chopped mat in shop; 1 layer of D, shop thickness 0.2mm glass fibre woven roving; Repeat B to D 1.2 times until part thickness; 5 layers on E, thickness 0.3mm surface, shop felt; Glass layer laying total height is 1.2～1.3 times of part thickness; Patrix is contained in the middle mould;
5) blending epoxy and curing agent and the degassing: blending epoxy and curing agent in the vacuum reaction still, ratio are 7:1;
6), injecting glue: inject mould, injecting glue pressure 100～300PSI with injection jar epoxy resin that will mix and outgas and curing agent;
7), pressure forming and curing: mould heated to be imposed 10Mpa pressure to 95-100 ℃ and exerts pressure and solidified 1 hour in forcing press.
The advantage of the invention: owing to adopted die forming, can guarantee by die size, not need to overlap again as the packing ring size; Owing to adopted degassing process, the little air gap of final product reduced; Electric insulating quality, mechanical strength, surperficial form and position tolerance and anti-leakage performance demands have been satisfied.
Description of drawings:
Fig. 1 is an integral molding epoxy glass fibre laminated insulating joint pad mould structure schematic diagram;
Among the figure: 1, positioning guide column 2, patrix 3, resin overflow launder 4, exhaust hole 5, middle mould 6, resin injection paths 7, counterdie 8, product
The specific embodiment:
Process for manufacturing integral molding epoxy glass fibre laminated insulating joint pad, its step is as follows:
1), mfg. moulding die: mould is made of positioning guide column, patrix, middle mould, counterdie, on middle mould upper surface, be shaped on resin overflow launder and 8 equally distributed exhaust holes, and 16 resin injection paths, positioning guide column is installed in the mesopore of counterdie, middle mould is installed on the counterdie, patrix is installed on middle mould and the positioning guide column; 16 resin injection paths and resin ester storage tank and injection device form the resin injection system; Mould is pressed the design of insulating joint shim size;
2), shear each layer fiber: press the dies cavity size and shear;
3), coating release agent: adopt polyvinyl alcohol and silica gel oil, when mould is warming up to 100～120 ℃, on mould inner surface, be coated with polyvinyl alcohol twice, after the drying, be coated with last layer silica gel oil again;
4), at each layer of mould middle berth fiber: shop layer order: A, thickness 0.3mm surface, shop felt are 5 layers from lower to upper; 1 layer on B, shop thickness 0.2mm continuous fiber felt; 1 layer of C, the cotton-shaped chopped mat in shop; 1 layer of D, shop thickness 0.2mm glass fibre woven roving; Repeat B to D 1.2 times until part thickness; 5 layers on E, thickness 0.3mm surface, shop felt; Glass layer laying total height is 1.2～1.3 times of part thickness; Patrix is contained in the middle mould; Surface felt, continuous fiber felt, cotton-shaped chopped mat and glass fibre woven roving are commercial product;
5), blending epoxy and curing agent and the degassing: blending epoxy and curing agent in the vacuum reaction still, ratio are 7:1; And the degassing, solve the technical problem that contains a large amount of little air gaps in the material, eliminate the internal stress that forms in the forming process, guarantee the plasticity and the intensity of finished product; Adopt CJ-50 vacuum reaction still;
6), injecting glue: inject mould with injection jar epoxy resin that will mix and outgas and curing agent; Injection speed is directly proportional with injection pressure, and the gel time of resin is regulated by the consumption of curing agent, guarantee that the gel of resin fully soaks into each layer fiber before; Injecting glue pressure 100～300PSI; Adopt MIX-126 injection jar
7), pressure forming and curing: mould heated to be imposed 10Mpa pressure to 95-100 ℃ and exerts pressure and solidified 1 hour in forcing press.Slowly carry out when exerting pressure, help to get rid of gas and make gasket surface not produce bubble, naturally cool to room temperature, the demoulding in about 10 hours.
The employing mould is made, and has solved effectively in the pad process, the technical problem that the little air gap that produces in particularly big knowledge, the large-diameter workpiece forming process and incidental compressive strength are low, surface wrinkling and form and position tolerance exceed standard.
Owing to adopted die forming, can guarantee by die size as the packing ring size, do not need to overlap again; Owing to adopted degassing process, the little air gap of final product reduced; Electric insulating quality, mechanical strength, surperficial form and position tolerance and anti-leakage performance demands have been satisfied.
The comparison of the fabric swatch of this explained hereafter and common fabric swatch beneficial effect:
