Abstract
The invention relates to a polymeric flexible graphite composite pressure leak stopping sealant, which adopts flexible graphite as the main material and other components: organic silicon material, carbon black, organic montmorillonite, graphite, silica, titanium dioxide, talcum powder, carbon fiber and aramid fiber; the weight percent of the components is as follows: 28.5 to 18.42 percent of organic silicon material, 57 to 55.25 percent of flexible graphite, 0 to 7.36 percent of organic montmorillonite, 5.7 to 7.36 percent of silica, 0 to 7.36 percent of talcum powder, 0 to 7.36 percent of titanium dioxide, 2.85 to 1.84 percent of carbon black, 2.85 to 5.52 percent of carbon fiber, and 2.85 to 2.72 percent of aramid fiber. The invention is characterized by high temperature resistance, good mobility, high elasticity, corrosion resistance and long storage time.
Description
Technical field
The present invention relates to a kind of pressure sealing sealing agent, particularly a kind of composite high molecular-flexible graphitic leakage blocking sealants with pressure.
Background technology
Though lay-by temperate zone means of press seals technology is not started late in China, develop rapider.Great majority are to be material of main part with synthetic rubber or synthetic resins in the market, and special these materials are easy to wear out under the environment of High Temperature High Pressure, and the pyritous rebound resilience is very poor, has caused the failure of plugging operations.And the self lubricity of these sealing agents is also not ideal enough, is difficult to accomplish the leak band means of press seals of valve packing letter.Be the sealing agent of material of main part with the synthetic rubber particularly, when deposit summer, be easy to bin cure, the shelf lives is shorter.
Summary of the invention
In view of the problem of above existence, the invention provides a kind of composite high molecular-flexible graphitic leakage blocking sealants with pressure, the storage time is long, can work under the environment of 200～800 degree, and can be with means of press seals to the leak of valve packing letter.
Concrete scheme is, a kind of composite high molecular-flexible graphitic leakage blocking sealants with pressure, it is characterized in that: the employing soft graphite is a material of main part, all the other components include, organosilicon material, carbon black, organo montmorillonite, graphite, white carbon black, titanium dioxide, talcum powder, carbon fibre, aramid fiber, the concrete weight proportion of its component is:
Organosilicon material: 28.5%～18.42%; Soft graphite: 57%～55.25%;
Organo montmorillonite: 0～7.36%; White carbon black: 5.7%～7.36%;
Talcum powder: 0～7.36%; Titanium dioxide: 0～7.36%;
Carbon black: 2.85%～1.84%; Carbon fibre: 2.85%～5.52%;
Aramid fiber: 2.85%～2.72%.
Characteristics of the present invention are: have high temperature resistant, good fluidity, high resilience, corrosion-resistant, the storage time is long.
Embodiment
Organosilicon material: select for use viscosity at 4000～8000 centistokes, hydroxy-end capped;
Organo montmorillonite: select X ray diffracting characteristic X-ray d 001nm 2.2～2.6 for use;
Soft graphite: content is more than 99%, and expansion multiple is 200%;
Concrete proportioning is an organosilicon material: 100, and soft graphite: 300, organo montmorillonite: 40, white carbon black: 15, talcum powder: 20, titanium dioxide: 40, carbon black: 5, the carbon fibre: 15, aramid fiber: 8.
Complete processing is:
1, earlier stirring in the adding of all material except that the organosilicon material colter formula stirrer, churning time was at 1 hour;
2, organosilicon material is poured in shutdown into, carries out the stirring of half hour again;
3, with the sizing material of blend, add in the forcing machine and extrude, extrude diameter and be the pole about 20MM, length is at 1.5M.
