Description
Technical field
The present invention relates to a kind of glue paste and compound method, relate in particular to a kind of glue paste and compound method that cork is bonding and repair that be used for, be mainly used in cork and paste with launch vehicle satellite fairing, two or three grades of inter-stage shells, booster rocket nose cone shells.
Background technology
Cork has heat-proof quality preferably, is widely used in civil area as lagging material, as thermos cork, is used for soft thin plate of process furnace, well heater and heat-insulating.Advantages such as cork has that thermal conductivity is low, light specific gravity, good manufacturability, cheap, wide material sources have also obtained application in space product.All post heat insulation cork shavings on Europe " Arian " launch vehicle satellite fairing and the three grade low-temp tanks; The CZ-3C of China, CZ-2E launch vehicle satellite fairing, two or three grades of inter-stage shells, booster rocket nose cone shells are covered with vegetable cork.CZ-2D instrument compartment thermofin was once imagined the employing vegetable cork.
The development of domestic miniaturization bullet is reflected in the requirement in the body solar heat protection of cabin, adopts certain thickness cork to replace coating, occurs in use that the cork top coat comes off and defective such as bulge unsticking.The major cause that produces these problems is: original tackiness agent (717 glue) that adopts is a polyurethane tackifier, belong to the moisture curing type tackiness agent, behind the product export with the increase of ambient relative humidity, 717 tackiness agent continue to solidify, 717 adhesive curings of cork periphery, inner 717 glue are in semi-cured state, and have micro-bubble because aqueous vapor can't enter.After dispatching from the factory, owing to envrionment temperature, pressure change, the small bubbles expansion causes back cork generation bulge, the unsticking problem of pasting.Analyzed the reason that causes matrix material cabin body cork sticking Quality problem in " stickup of matrix material cabin body cork " delivered on the 5th phase of calendar year 2001 " aerospace material technology ", and the technical qualification of pressing GD414 and 717 glue, HYJ-51, J-48 glue and GD414,717 glue are compared, select for use HYJ-51 glue to carry out the technology suitability and improve glue paste bonding as cork and that repair, disclose the present invention in the literary composition and developed the roughly prescription and the content at initial stage, introduce the performance and the purposes of this type tackiness agent, unexposed concrete formulation content and compound method.
Summary of the invention
Technology of the present invention is dealt with problems: overcome the deficiencies in the prior art, a kind of glue paste and compound method that cork is bonding and repair that be used for is provided, the present invention can use in wide temperature range-40 ℃～250 ℃, all can obtain higher bonding strength, and the influence of back with ambient relative humidity, pressure of not dispatched from the factory, can make cork and paste glue, can make the cork repair sheets again, has extensive applicability, and bonding, repair technology is easy, and compound method of the present invention is simple, workable.
Technical solution of the present invention is: a kind ofly be used for the glue paste that cork is bonding and repair, its component and weight percent are:
Resol mixture: 28%～77%
Silicon powder: 16%～59%
Solidifying agent: 7%～13%
Wherein: the resol mixture is made up of 50%～70% F-51 novolac epoxy, 23%～32% ethylene glycol diglycidylether, 6%～10% random carboxyl liquid acrylonitrile butadiene rubber and 1%～8% KH-550;
Solidifying agent is made up of 40%～55% dehydrated alcohol, 25%～35% imidazoles and 20%～25% tetraethylene pentamine.
Above-mentioned silicon powder is an active micro silicon powder, and wherein the grain particle diameter is 15～125 μ m.
A kind of bonding compound method with the glue paste of repairing of cork that is used for may further comprise the steps:
(1) getting F-51 novolac epoxy and random carboxyl liquid acrylonitrile butadiene rubber earlier places the interior preheating 30 ± 5min of 60 ± 5 ℃ of baking ovens to be used to reduce viscosity;
(2) will reduce random carboxyl liquid acrylonitrile butadiene rubber, KH-550 after F-51 novolac epoxy after the viscosity, ethylene glycol diglycidylether, the reduction viscosity by the described formulation content of claim 1 then adds in the container successively and stirs, mixing speed is 50～300r/min, forward and backward respectively stirs 1.5～10min, move up and down agitator arm simultaneously, form the resol mixture; Equally, by the described formulation content of claim 1 imidazoles, dehydrated alcohol are added in the container successively, and stir, be dissolved in fully in the dehydrated alcohol, add tetraethylene pentamine again and stir, form solidifying agent until imidazoles;
(3) add resol mixture, solidifying agent, silicon powder in the container successively by the described formulation content of claim 1 at last and stir, the rotating speed that stirs is 50～300r/min, forward and backward respectively stirs 1.5～10min, move up and down agitator arm simultaneously, become tackiness agent bonding or that repair.
The present invention's advantage compared with prior art is:
(1) because present 717 used glue belongs to the moisture curing type tackiness agent, and the present invention is a phenolic aldehyde epoxies tackiness agent, prescription itself has the solidifying agent of enough content, guarantee that tackiness agent prepares back completely solidified in the time that requires, the problem that does not have semicure, the influence of back of not dispatched from the factory with ambient relative humidity, pressure; The micro-bubble that tackiness agent of the present invention in addition produces seldom can be ignored, even there is micro-bubble, also can not cause back cork generation bulge, the unsticking problem of pasting owing to envrionment temperature, pressure change expansion; After adding this polar solvent of resol mixture, improved tackiness agent and cut intensity drawing of room temperature and 250 ℃.
(2) compound method of the present invention is very simple, need under particular surroundings, not carry out, process for preparation only need change stir speed (S.S.) and churning time can realize by purposes, tackiness agent by this compound method preparation can use in wide temperature range (40 ℃～250 ℃), all can obtain higher bonding strength, both can realize bonding at normal temperatures, 60 ℃～100 ℃ curing of the condition of can under situation about being pressed for time, heating again, improve bonding strength with this, the present invention can make cork and paste glue, can make the cork repair sheets again, has extensive applicability, bonding, the repairing implementing process is easy, and technology is workable.
