Description
Technical field
Product of the present invention belongs to chemical field, particularly relates to a kind of preparation method of resol electro-conductive adhesive.
Background technology
Electro-conductive adhesive is that one can glued joint various material effectively, there is again the tackiness agent of conductivity, electro-conductive adhesive can be divided into structure-type and the large class of filled-type two, and structure-type refers to that namely the macromolecular material itself as conductive resin matrix has the conductive resin of electroconductibility; Filled-type refers to that usual tackiness agent is as matrix, and rely on interpolation electroconductive stuffing to make glue have the conductive resin of electric action, the preparation of current conducting polymer composite is very complicated, also have larger distance from practical application, is therefore widely usedly filled conductive glue.The electroconductive stuffing that filled conductive glue stick adds, is metal-powder usually.Electro-conductive adhesive is usually used in microelectronics assembling, comprise thin wire to be connected with printed wiring, plated board, the metal level of ceramic adherend, metal chassis, bonding wire and base, bonding element with through the plane hole of printed wiring, the tuning and hole of bonding waveguide is repaired.The complex material that electro-conductive adhesive is made up of the electroconductive stuffing such as metal powder or graphite and synthetic resins, it is main moiety with matrix resin and conductive filler material and conducting particles usually, by the bonding effect of matrix resin, conducting particles is combined, form conductive path, the conduction realized by gluing material connects.The metallics that electro-conductive adhesive uses has: the powder of gold and silver, copper, aluminium, zinc, iron, nickel and graphite and some conductive compounds; The body material that uses has conventional as adhesive systems such as epoxy resin, silicone resin, polyimide resin, resol, urethane, acrylic resins.These tackiness agent define the molecular skeleton knot of electro-conductive adhesive after hardening, provide mechanical property and adhesiveproperties guarantee, and make conductive filler particles form passage.The present invention selects resol and copper powder to be that main raw material is to produce resol electro-conductive adhesive.The major advantage of use resol is: resol has excellent thermotolerance, flame resistivity, water tolerance, acid resistance better, mechanical and electric property is good, especially cheap, add different auxiliary materials when making tackiness agent, the synvaren of Various Functions can be obtained.The present invention with liquid phenolic resin, epoxy resin, epoxy resin diluent, paracril, polyvinyl butyral acetal, silane coupling agent, diphenylmethanediamiand, copper powder for raw material, and be aided with certain processing condition to produce resol electro-conductive adhesive, the advantage of this preparation method is: use general-purpose equipment, production technique simple, end-use is extensive.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of method producing resol electro-conductive adhesive in batches, the method is with liquid phenolic resin, epoxy resin, epoxy resin diluent, paracril, polyvinyl butyral acetal, silane coupling agent, diphenylmethanediamiand, copper powder is raw material, and be aided with certain processing condition to produce resol electro-conductive adhesive, the raw material weight proportioning of producing the use of this product is: liquid phenolic resin 32-34%, epoxy resin 4-6%, epoxy resin diluent 12%, liquid nitrile rubber 2%, polyvinyl butyral acetal 2%, silane coupling agent 2%, diphenylmethanediamiand 1%, copper powder 43%.
The present invention can be achieved through the following technical solutions:
A preparation method for resol electro-conductive adhesive, its feature is made up of following steps:
1. the liquid phenolic resin of formula ratio is sent into the first agitator tank, start stirrer, rotating speed is 20 revs/min, after temperature being elevated to 35-40 DEG C, the liquid nitrile rubber of formula ratio is sent into the first agitator tank, is cooled to normal temperature after stirring.
2. the epoxy resin diluent of formula ratio is sent into the second agitator tank, start stirrer, rotating speed is 25 revs/min, add epoxy resin, polyvinyl butyral acetal, silane coupling agent, the diphenylmethanediamiand of formula ratio at normal temperatures successively, after stirring reaction 0.5-0.7 hour, the mixture of liquid phenolic resin and liquid nitrile rubber is added the second agitator tank, adds the copper powder of formula ratio after stirring reaction 0.3-0.4 hour, stir and get product.
Temperature of reaction in the first agitator tank described in step (1) is 37.5 DEG C.
Normal temperature in the second agitator tank described in step (2) is 5-30 DEG C.
The invention has the beneficial effects as follows: the preparation method providing a kind of resol electro-conductive adhesive, this preparation method uses that general-purpose equipment, production technique are simple, product price is cheap, and product can at room temperature solidify, of many uses, and has extremely low resistivity.
