Abstract

The invention discloses an intermediate temperature resisting vacuum bag sealing adhesive tape which is characterized by being prepared by adopting butyl rubber, polyisobutene and nano calcium carbonate as main matrixes and assisting to add a recessive high temperature vulcanized agent through steps of stirring and mixing, extruding and forming. The intermediate temperature resisting vacuum bag sealing adhesive tape does not leak gas during vacuumizing, has no residual glue after demoulding, and has good high temperature resistance, and the maximum high temperature limit can reach 150 DEG C.

Description

Warm vacuum bag sealing adhesive tape in anti-
Technical field
The present invention relates to a kind of sealant tape, particularly a kind of high temperature resistant vacuum bag sealing adhesive tape technical field.
Background technology
Along with rapid development of economy, new forms of energy, spationautics have also entered a high-speed development period in China.In recent years, country greatly develops wind energy power technology and big aircraft manufacturing technology, but much technology is all monopolized by western developed country, especially in wind-power electricity generation industry and space industry, in the manufacturing processed of fan blade and aircraft, need sealing between vacuum bag and the making mould.Vacuum bag also claims the decompression packing, carry out according to the normal atmosphere principle, the main effect of vacuum bag is deoxygenation, promptly in the manufacturing processed of fan blade and aircraft, need between vacuum bag and the grinding tool to seal when vacuumizing, this seals with regard to the adhesive tape that needs favorable sealing property.
In the manufacturing processed of fan blade and aircraft, all be to use resin, as unsaturated polyester or Resins, epoxy and fiber, pass through mould molding as glass fibre or carbon fiber, to use the vacuum bag sealing to vacuumize in the manufacturing processed, be vacuum bag and make between the mould and need adhesive tape to seal between vacuum bag and the vacuum bag, can there be some problems in the sealant tape of prior art: (1) high thermal resistance is poor: because of material resin is to vacuumize while heating in moulding process, so to the high temperature resistant of sealant tape is that very high requirement is arranged, the sealant tape resistance to elevated temperatures of prior art is low; (2) spatter property of the demoulding: construction for convenience, many manufacturerss require the sealant tape demoulding to make things convenient for, and do not allow any cull and stay on the mould, and this also is prior art can't satisfy a bit.Gas leakage when existing sealant tape vacuumizes in addition, shortcoming such as separate-type paper and glue disengaging during construction.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of high temperature resistant vacuum bag seal gum, the highest high temperature resistant temperature can reach 150 ℃, does not have cull when breaking away from the making mould and is trapped on the mould.
The present invention realizes by following technical scheme:
A kind of high temperature resistant vacuum bag sealing adhesive tape, be to be main matrix with isoprene-isobutylene rubber, chloroprene rubber, polyisobutene and nano-calcium carbonate, auxiliary recessiveness high temperature vulcanized dose and other substance of adding, extrusion moulding after mixing, its component content parts by weight are as follows:
Main matrix: isoprene-isobutylene rubber 10-15 part, polyisobutene 15-20 part, nano-calcium carbonate 25-35 part;
Recessive high temperature vulcanized dose: 1.5-2.0 part;
Other substance: superfine talcum powder 25-35 part, zinc oxide 1.5-2.0 part, stearic acid 0.5-1.5 part, tackifying resin 1-2 part, carbon black 2-2.5 part, softening agent 1.5-3 part.
Described recessiveness is resol for high temperature vulcanized dose, and its component content parts by weight are 1.5-2.5 part.
Described softening agent is a dioctyl phthalate (DOP).
Beneficial effect of the present invention is: air tight when vacuumizing in the manufacturing processed of fan blade and aircraft, the high energy of high thermal resistance reaches 150 ℃, does not have cull to stay on the mould, and separate-type paper can not break away from seal gum etc. during construction.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
The present invention is to be main matrix with isoprene-isobutylene rubber, polyisobutene and nano-calcium carbonate, auxiliaryly adds recessive high temperature vulcanized dose and other substance, extrusion moulding after mixing.Its action principle is to utilize the resistance to air loss of isoprene-isobutylene rubber, adds the chloroprene rubber high thermal resistance, as the recessive vulcanizing agent of high temperature, plays due effect with resol.Chloroprene rubber, glass fibre and resol in its prescription can make the leading prior art of performances such as high thermal resistance of the present invention and release property a lot.
