Abstract
The invention discloses a high-temperature-resistant vacuum bag sealing adhesive tape, which is formed by stirring, mixing and extruding butyl rubber, chloroprene rubber, cardanol modified phenol-formaldehyde resin, nano calcium carbonate, glass fiber, superfine talcum powder, zinc oxide, stearic acid, tackifying resin, titanium dioxide and dioctyl phthalate. The high-temperature-resistant vacuum bag sealing adhesive tape has the beneficial effects that no air leakage is caused during vacuuming in a manufacturing process of a fan blade and an airplane, the maximum service temperature can reach 425 DEG C, and meanwhile, no residual adhesive is remained on a mold when the high-temperature-resistant vacuum bag sealing adhesive tape is separated from the manufacturing mold.
Description
Technical field
The present invention relates to a kind of sealant tape, particularly a kind of high temperature resistant vacuum bag sealing adhesive tape.
Background technology
In the manufacturing processed of fan blade and aircraft, between vacuum bag and making mould, need sealing.Vacuum bag also claims decompression packing, according to atmosphere principle, carry out, the Main Function of vacuum bag is deoxygenation, in the manufacturing processed of fan blade and aircraft, between vacuum bag and mould, need when vacuumizing, seal, this just needs the adhesive tape of favorable sealing property to seal.
In the manufacturing processed of fan blade and aircraft, all to use resin, as unsaturated polyester or epoxy resin and fiber, as glass fibre or carbon fiber pass through mould molding, manufacturing processed will be used vacuum bag sealing to vacuumize, be vacuum bag and make between mould and need adhesive tape to seal between vacuum bag and vacuum bag, can there are some problems in the sealant tape of prior art: (1) high thermal resistance is poor: because material resin is to vacuumize while heating in moulding process, so be to have very high requirement to the high temperature resistant of sealant tape, the sealant tape resistance to elevated temperatures of prior art is low, (2) spatter property of the demoulding: for convenient construction, many manufacturerss require the sealant tape demoulding to facilitate, and have not allowed any cull to stay on mould, and this is also prior art cannot meet a bit.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high temperature resistant vacuum bag sealing adhesive tape for the existing problem of prior art, and its maximum operation (service) temperature can reach 180 ℃, and depart from making mould is not have cull to be trapped on mould simultaneously.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A high temperature resistant vacuum bag sealing adhesive tape, is characterized in that, by raw material extrusion moulding after being uniformly mixed of following weight part:
Isoprene-isobutylene rubber: 8-10 part;
Chloroprene rubber: 10-12 part;
Cardanol Modified PF Resin: 1.5-2.5 part;
Nano-calcium carbonate: 30-35 part;
Glass fibre 3-6 part, length is 5-6mm;
Superfine talcum powder 25-30 part;
Zinc oxide 1.6-2.0 part;
Stearic acid 0.5-1.2 part;
Tackifying resin 2.0-2.5 part;
Titanium dioxide: 1.0-1.5 part;
Dioctyl phthalate (DOP) 1.0-1.4 part.
Beneficial effect of the present invention is: in the manufacturing processed of fan blade and aircraft, air tight while vacuumizing, maximum operation (service) temperature can reach 180 ℃, and depart from making mould is not have cull to be trapped on mould simultaneously.
