Description
Technical field
The present invention relates to a kind of fast repairing agent, the two quick tackiness agent of component response type of especially a kind of epoxide modified ambient cure.
Background technology
Surface Engineering is paid much attention to day by day as the important means of maintenance.As Surface Engineering subject important component part n9 sufacing, the surface recovery technique comprises that platings, brush plating, thermospray, bonding gluing are coated with etc., these restorative procedures replenish mutually, become the means emergency schedule of maintenance of equipment necessity, repair scrapped parts, old part is come back to life, and for enterprise retrieves the tremendous economic loss, maintenance of equipment has become the organic component of productivity.
The surface cohering technology in recent years, has been brought into play significant role and has been obtained good social benefit and huge economic benefit as representing one of surface technology in the maintenance of equipment field.
The surface cohering technology is compared with built-up welding, thermospray, brush plating, its technology is easy, do not need Special Equipment, need not to consume heat energy and electric energy, only need the face of repairing watch of waiting that it is good that the healant for preparing is coated on cleaning is got final product, solidify the back as hard as the metal, can carry out various mechanical workouts, satisfy that part is wear-resisting, anti-corrosion, maintenance needs such as resizing, defective are filled up, sealing and plugging.General ambient temperature curable does not have heat affected zone and thermal distortion to part, but and site work, reduce stop time.Its time and labour saving, save energy and substantial contribution are a kind of quick and inexpensive repairing techniques, are the effective means of maintenance of equipment, will develop into important one of the surface technology of representing.
Metal repairing agent is the gordian technique of surface cohering and splicing in the maintenance of equipment; it is by high molecular polymer and metal-powder; ceramic powder and fibrous pair of component (or many components) clay shape matrix material; it is wear-resistant to be widely used in part; corrosion-resistant reparation is with pre-supercoat and be used for repairing the various defectives of part (as crackle; scratch; dimension overproof; blow hole; sand holes) and sealing and plugging etc.; its technology is simple and easy to do; only need two components are mixed in proportion; be coated on through rust cleaning; the surface of oil removing; solidifying the back finishing gets final product; be a kind of saving of labor; save time; economical; durable; flexibly; convenient; desirable novel patching material is one of matrix material at present with fastest developing speed.
This patching material abroad just begins one's study from the fifties end, U.S. Belzona high polymer alloy healant for example, Germany Diamant product is also world-famous, can be used to repair various materials, can be used for repairing metal, rubber, pottery etc., can select the healant of the different trades mark according to conditions such as different use temperatures, pressure, media for use.The MEcATeC product of Switzerland Castolin company also has tens kinds, has obtained using widely in the maintenance of equipment of multiple industries such as casting, cement, sugaring, railway, electronics.In addition, fill up agent, wear-resisting glue though more domestic units develop some metals, performance can't satisfy the service requirements of maintenance of equipment.The patching material of above-mentioned external development, though performance is higher than home products, China's the eighties was just once used German Diamant product to tank track kiss-coating plate, but intensity, heat resistance still are difficult to reach the requirement of the equipment of repairing performance requriements harshnesses such as war industry equipment or intensity, and the price of import healant and costliness thereof, consume a large amount of foreign exchanges, cause enterprise aspect maintenance of equipment, to consume a huge sum of money.
The serial fast repairing agent of the present invention's development is the two component response type healants of ambient cure, has than epoxy, and glue kind commonly used such as anaerobism is excellent comprehensive performances more, cured glue layer gray, and bonding strength reaches 43MPa, 60～180 ℃ of use temperatures.Be mainly used in fuel tank, water tank, air delivering pipeline sealing and leak stopping.
Summary of the invention
The composition of healant can be divided into sizing, solidifying agent, toughner, particular fillers, thinner, coupling agent, anti-aging agent, thixotropic agent, defoamer, promotor etc.Sizing is selected Resins, epoxy, resol, unsaturated polyester, urethane, silicone resin etc. for use, and filler can be divided into metal-powder (as iron powder, aluminium powder, copper powder, lead powder etc.), ceramic powder (WC, SiC, A1
2O
3, BC, Cr
2O
3, SiO
2, quartz sand etc.) and graphite, MoS
2, polytetrafluoroethylenes etc. are material fast.Two two component healants, two components are mixed use by a certain percentage during coating, generally are made up of sizing, solidifying agent and filler (abbreviation particular fillers) and subsidiary material with certain characteristic (wear-resisting, against corrosion, insulation, conduction etc.).
1, sizing
Or the title base-material, as thermosetting resin, synthetic rubber etc.Thermosetting resin such as epoxy, phenolic aldehyde, urethane, unsaturated polyester, acrylic acid ester etc. have the three-dimensional crosslinking structure, and are heat-resisting, water-fast, resistance to medium is good, use more in healant.The effect of sizing is the various materials in the healant to be contained and stick to matrix surface securely to form coating, therefore, and for the sizing of adhesive coating layer should have following performance:
(1) coated matrix and filler there is higher binding strength.
(2) cured article should have higher physical strength and good heatproof, oil resistant, chemically-resistant and ageing resistance, and its Young's modulus and stability want high.
(3) the cured article shrinking percentage is little.
2, solidifying agent
The effect of solidifying agent is and sizing generation chemical reaction, forms netted space polymer, and the filler envelope in the body of dictyosome, is formed the crosslinked combination of three-dimensional.
Requirement with solidifying agent is generally to healant:
(1) cured article hardness height, good toughness, wear resistance is good, and solidity to corrosion, medium-resistance are good etc.
(2) preferably can self-vulcanizing, set time is short.
Healant of the present invention is generally amine curing agent with solidifying agent, adopts aminated compounds as solidifying agent, makes healant that higher degree of cure and outstanding resistance toheat be arranged.
3, particular fillers
Particular fillers plays important effect in healant, as wear-resistant quick, anti-corrosion, insulation, conduction etc.Therefore the selection of particular fillers is most important to the performance of coating, needs and the chemical terms consideration from maintenance, filler is required be:
(1) filler should be neutral or weakly alkaline, does not contain in conjunction with water, and is good with the sizing affinity, and liquid is not had adsorptivity or adsorptivity is seldom arranged.
(2) filler absorption impurity enough thermotolerances and certain purity will be arranged, if can cause the resin degraded.
(3) require particle or grain density little, scattered, sedimentation is little in resin.
The healant filler comprises powder or the fiber with a certain size; as hard particles such as metal-powder, oxide compound, carbide, nitride even diamond, boride or fiber, graphite, molybdenumdisulphide, polytetrafluoroethylene etc., according to the wear-resistant filler of the optional hard of different coatings.
4, subsidiary material
Subsidiary material comprise toughner, plasticity, thinner, curing catalyst (as tertiary amines altax P-30 etc.), coupling agent, defoamer, anti-aging agent etc., its effect be improve coating performance such as toughness, resistance to deterioration etc. and reduce glue viscosity, improve coating quality etc.
According to above-mentioned four kinds of component roles, according to different working conditionss and performance requriements, through testing preferred suitable material and proportioning, the healant of preparation various requirement.
In addition, the present invention also provides the production method of above-mentioned fast repairing agent.
