Amount is 1000-5000；The inorganic filler is the inert filler of low oil absorption；
(2) polyisobutene is added in kneader with antioxidant and is mediated, kneading time controls in 20-40min；
(3) after polyisobutene and antioxidant are mediated completely, inorganic filler is added into kneader and continues to mediate, kneading time control
System is in 50-80min；
(4) after being sufficiently mixed, plasticizer, Sodium Polyacrylate are added, continues to discharge after mediating 20-40min；
(5) by the filling glue inlet tube of filling apparatus.
As a preferred embodiment, the raw material components include: polyisobutene 30-50wt%, inorganic filler 35-50wt%,
Plasticizer 7-12wt%, Sodium Polyacrylate 7-15wt%, antioxidant 0.2-0.5wt%, pigment 0.0002wt%；The pigment waits gathering different
Butylene, inorganic filler, antioxidant after mixing, are added together with Sodium Polyacrylate, plasticizer.
As a preferred embodiment, the inorganic filler is the one or two of barium sulfate, talcum powder.
As a preferred embodiment, the plasticizer is naphthenic oil.
As a preferred embodiment, the antioxidant is antioxidant 1010.
As a kind of more preferable scheme, the pigment is that titanium cyanines are blue or titanium cyanines are green.
As a preferred embodiment, the kneader temperature control is at 100-130 DEG C.
The beneficial technical effect of the present invention lies in:
(1) present invention is more soft dilute compared to conventional viscoelastic body cream, carries out suitable for special-shaped equipment or tube surface hole
Anti-corrosion filling, can bring great convenience to anticorrosive construction, since the invention belongs to a kind of never cured viscoplasticity polymerizations
Object is not limited by void shape, and powerful cold flow characteristic can generate further infiltration over time, has been reached
Full packing corrosion-resistant effect.
(2) anti-corrosion effect of the present invention is splendid, due to using polyisobutene and inert filler as raw material completely, not only fills out
Fill that effect is good, improve the leakproofness of entire erosion resistant coating, itself have it is excellent block water, it is resistant to chemical etching and resist microorganism
The performances such as corrosion, can greatly improve the service life of equipment.
(3) present invention is good to multiple material adhesion strength, and 85 DEG C without dripping phenomenon of hanging down, long-term test without cathodic protection removing with
Chemical mediator corrosion phenomenon, therefore it is very suitable to the long-term anti-corrosion protection of metal equipment.
