The adhesive is composed of one component comprising by weight 25-35 parts of bisphenol A diglycidyl ether, 0.3-0.7 part of organic polysiloxane,48-65 parts of a metal powder, 2-12 parts of gaseous phase white carbon black, 30-50 parts of a curing agent, 25-45 parts of a low-molecular polyamide resin and 15-25 parts of gaseous phase silica. Compared with the prior art, the invention has the following advantages: 1, the metal repair adhesive has high bond strength and hardness; 2, after curing, the hardness and strength can meet the requirements of machining; and 3, the repair adhesive provided by the invention can be bonded to a metal surface with oil or water, and can cure in oil or water.
Description
Technical field
The present invention relates to the metallic prosthetic caking agent that mechanical workout is used, belong to the Machining Technology field.
Background technology
At chemical industry, machinery, water supply, heating, air feed, in the industries such as oil, weldering knot to metal tube or device is generally to adopt the hot weldings such as electric welding, gas welding to complete, the basic functional principle of electric welding is us by the 220V voltage of commonly using or the commercial power of 380V, reduced voltage by the pressure reducer in welding machine, strengthened electric current, and made electric energy produce huge electric arc heat thawing iron and steel.And welding rod to incorporate the amalgamation that makes between iron and steel higher, the flame that utilizes inflammable gas and combustion-supporting gas mixed firing to generate is thermal source, fusing weldment and welding material make it to reach a kind of welding process of interatomic bond, but heat weldable shortcoming one is to use in the occasion such as inflammable, explosive, the 2nd, need to use power supply or fuel source etc., working conditions has been subject to certain restriction.And existing tackiness agent majority is for various non-metallic material such as bonding timber, plastics, glass, and its cohesive strength is generally lower, and various metallic substance are unsuitable for boning.The binding agent that also has minority to be made for Main Components by phenolic aldehyde one ethene, Polyurethane and epoxy resin etc. can be used for matrix metal, but the shortcoming of these binding agents mainly contains following four. and the one, its hardness is less, generally at l 7kg/cm.Below the left and right, and its intensity is lower, general intensity far below metal parts, the 2nd, find and can not bond on the surface with oil or water through using, and during practical application most bonded metal material surfaces all in various degree be stained with oil or water, like this or must carry out cleaning, drying to the material surface of bonding, bring very large trouble to use, or can not clean or be difficult for cleaning up the effect that has limited its use range or affected bonding because of the material surface of bonding; The 3rd, because the physical strength after its bonding is less, especially because hardness is lower, can not meet the requirement of mechanical workout; The 4th, generally can only be used for the bonding between material, can not be used for the reparation on textural defect.
Summary of the invention
In order to overcome above-mentioned deficiency, the metallic prosthetic caking agent that the object of the present invention is to provide mechanical workout to use can satisfy the requirement of mechanical workout, can carry out the metal-repairing binder of mechanical workout.
The technical scheme that the present invention takes: the invention provides a kind of metal-repairing binder that carries out mechanical workout, this binding agent is made of a component, and its weight percent consists of.
Bisphenol A diglycidyl ether class 25～35
Organopolysiloxane 0.3～0.7
Metal-powder 48～65
Gas phase White Carbon black 2～12
Solidifying agent 30～50
Low molecule pa resin 25～45
Aerosil 1 5～25
bisphenol A diglycidyl ether class described in the present invention is the parent tackiness agent of this binding agent, polymerization in main rising, it can be bisphenol A diglycidyl ether, can be also its derivative, for example. methylol dihydroxyphenyl propane glycidyl ether, dihydroxyphenyl propane side group epoxy resin etc., described organosilane is the metal affinity agent in this binding agent, and its Main Function is surface tension and the surface energy that changes metal-powder and matrix material, improves the cohesive strength of binding agent and the cohesive strength of metallic substance, can adopt various organosilanes, described metal-powder uses as the additive of binding agent, can select aluminium powder according to the difference of matrix material, titanium valve, iron powder, Stainless Steel Powder, alloy powder, copper powder etc., also can come the Substitute For Partial metal powder with ceramic powder, its role is to improve the hardness after binding agent bonds, intensity and machinable, for matrix material provides molecular source, so that under the effect of metal affinity agent, be diffused in matrix material, the formation molecular linkage connects, reach the purpose of secure bond, described aerosil uses as thixotropic agent in this binding agent, prevent caking agent layering and mummification, the solidifying agent that described solidifying agent is the bisphenol A diglycidyl ether class as the parent tackiness agent uses, its role is to impel parent tackiness agent polymerizing curable, can adopt the various aliphatics amines that can impel the very fast polymerizing curable of parent tackiness agent, alicyclic amine, the aromatic amine solidifying agent, as commercially available solidifying agent JA-I, solidifying agent 881, solidifying agent TW-34 etc., know through test, with solidifying agent 881, 34 two kinds of solidifying agent of solidifying agent TW-are take 1: the ratio of ~ 6～6:1 is carried out mixed mixed curing agent effect as better, the effect of Versamid mainly has been plastification and the bisphenol A diglycidyl ether class has been carried out modification, to change the fragility after its polymerization.
Embodiment
The formula of three specific embodiment weight percents of the present invention is composed as follows.
