Abstract
The high-temp. anti-sticking anticorrosive paint for rubber mould and reactor contains polyphenyl thioether (70-90%), graphite (4-20%), teflon (4-20%), Co2O3 (0.5-5%) and MoS2 (0.5-5%), and has better thermal stability and anti-ageing nature.
Description
The invention belongs to the technical field of coating, be specifically related to a kind of high temperature antisticking corrosion-proof paint.
At present, the coating effect of metal material surface is all more single, lack and possess chemical resistance simultaneously, thermotolerance, ageing resistance, tack, mechanical property, dimensional stability, the coating that over-all propertieies such as security are all good, Chinese patent 91103301.7 discloses a kind of by novolac epoxy, paracril, Resins, epoxy, tetrafluoroethylene, the melamine cyanurea complex compound, cupric oxide or aluminum oxide or Cadmium oxide, Tetra hydro Phthalic anhydride or diamines, organic mixed solvent (acetone 30-50%, butanone 8-20%, propyl carbinol 20-40%, toluene 0-26%) anticorrosive antisticking and wear proof lubricating painting materials of Zu Chenging, this coating has concurrently anticorrosion, antiseized, effect such as wear-resistant, but its thermostability, ageing resistance is relatively poor.
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of protection against corrosion at high temperature, antiseized is provided, thermostability and ageing resistance all are better than the high temperature antisticking corrosion-proof paint of existing coating.
The objective of the invention is such realization:
High temperature antisticking corrosion-proof paint of the present invention is by polyphenylene sulfide, graphite, poly-tetrem alkene, Co
2O
3And MoS
2Form.
Specifically the consisting of of high temperature antisticking corrosion-proof paint of the present invention (weight ratio): polyphenylene sulfide 70-90%, graphite 4-20%, tetrafluoroethylene 4-20%, Co
