Abstract
The present invention relates to a bonding agent based on epoxy or epoxy derivative, mainly solving the disadvantages of the the existent bonding agent used for bonding metal material are low in strength and hardness, and after having been bonded it cann't meet the requirements for mechanical machining, and is not applicable to bonding greasy and wet surface. Said bonding agent consists of both constitutents of A and B, and A constituent consists of bisphenol-A diglycidyl ethers, organic silicane, metal powder and gas-phase silicon dioxide, and B constituent consists of solidifying agent, low-molecular polyamide resin, gas-phase silicon dioxide and organic silicane. It is suitable for repairing and binding various metal materials.
Description
The present invention relates to a kind of tackiness agent based on Resins, epoxy or epoxy resin derivant.
In industries such as chemical industry, machinery, water supply, heating, air feed, oil, weldering knot to metal tube or device generally is to adopt hot weldings such as electric welding, gas welding to finish, but heat weldable shortcoming one is to use in occasion such as inflammable, explosive, the 2nd, need to use power supply or fuel source etc., make working conditions be subjected to certain restriction.And existing tackiness agent majority is to be used to bond various non-metallic material such as timber, plastics, glass, rubber, 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 component by phenolic aldehyde-ethene, Polyurethane and Resins, epoxy etc. can be used for matrix metal, but the shortcoming of these binding agents mainly contains following four: the one, and its hardness is less, generally at 17kg/cm
2About below, and its intensity is lower, generally far below the intensity of metal parts; The 2nd, find and can not bond through using on the surface that has oil or water, 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 agglutinating material surface, bring very big trouble to use, or can not clean or be difficult for cleaning up and limited its use range or influenced the agglutinating effect because of the agglutinating material surface; The 3rd, less because of the physical strength after its bonding, especially because of hardness is lower, do not satisfy the requirement of mechanical workout; The 4th, generally can only be used for the bonding between the material, can not be used for the reparation on the textural defect.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art and a kind of cohesive strength is provided and hardness is higher, can satisfy mechanical workout requirement, can carry out the metal-repairing binder of mechanical workout.
For finishing above-mentioned purpose, the invention provides a kind of metal-repairing binder that carries out mechanical workout, this binding agent is made of the two components of A, B, and special character of the present invention is that the weight percent of A, B two components consists of:
The A component
Bisphenol A diglycidyl ether class 20～45
Organosilane 0.2～0.9
Metal-powder 50～75
Aerosil 1～14
The B component
Solidifying agent 25～60
Low molecule pa resin 20～50
Aerosil 15～25
Organosilane 1.5～3
Bisphenol A diglycidyl ether class described in the present invention is the parent tackiness agent of this binding agent, polymerization in main the rising, it can be a bisphenol A diglycidyl ether, also can be its derivative, for example: methylol bisphenol A diglycidyl ether, dihydroxyphenyl propane side links epoxy resins etc.; Described organosilane is the metal affinity agent in this binding agent, and it mainly acts on 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, difference according to matrix material can be selected aluminium powder, titanium valve, iron powder, Stainless Steel Powder, alloy powder, copper powder etc. for use, also can use ceramic powder to substitute the part metals powder, its role is to improve hardness, intensity and machinable after binding agent bonds, for matrix material provides molecular source,, be diffused in the matrix material so that under the effect of metal affinity agent, the formation molecular linkage connects, and reaches the purpose of secure bond; Described aerosil uses as thixotropic agent in this binding agent, prevents caking agent layering and mummification; Described solidifying agent is the solidifying agent use of bisphenol A diglycidyl ether class as the parent tackiness agent, its role is to impel parent tackiness agent polymerizing curable, can adopt and variously can impel the aliphatics amine of the very fast polymerizing curable of parent tackiness agent, alicyclic amine, aromatic amine solidifying agent, as commercially available solidifying agent JA-1, solidifying agent 881, solidifying agent TW-34 etc., know that through test it serves as better carrying out mixed mixed curing agent effect with solidifying agent 881, two kinds of solidifying agent of solidifying agent TW-34 with 1: 7～7: 1 ratio; The effect of Versamid mainly has been plastification and the bisphenol A diglycidyl ether class carried out modification, to change the fragility after its polymerization.
The prescription of three specific embodiment weight percents of the present invention is composed as follows:
Embodiment 1:
The A component
Bisphenol A diglycidyl ether 22.3
Organosilane 0.3
Aerosil 13.4
