Abstract
The invention discloses a preparation method of a spot-weld adhesive and belongs to the field of chemical industry. According to the method, E-44 epoxy resin, 501 epoxy diluent, a KH-550 coupling reagent, hydroxyl alkylene oxide, liquid polyamide resin, maleic anhydride, m-xylylenediamine and asbestos powder are used as raw materials, and a chemical reaction kettle is taken as a reaction container to prepare the spot-weld adhesive. The preparation method has the advantages that the production technology is simple, universal equipment is adopted, the spot-weld adhesive has the advantages of good connection strength, good sealing performance, good fatigue durability, uniformly distributed stress, light structural weight, capability of performing anodic oxidation, high productivity and the like, and the spot-weld adhesive can be applied to the spot weld-bonding of metal materials, such as aluminum and aluminum alloy, and fiber glass reinforced plastics.
Description
Technical field
Product of the present invention belongs to chemical field, relates in particular to a kind of preparation method of spot-weld adhesive.
Background technology
Spot welding is weld-bond joint, it is a kind of advanced material composite joint form of novelty, the strength of joint of weld-bond joint is high, good airproof performance, as the adhesive spots weldment is carried out anodic oxidation, then can be in weld seam residual acid, alkali lye and produce corrosion, and structural part weight saving, stress distribution is even, spot welding place good looking appearance.The adhesive spots welding method can be divided into first glue backward welding according to the gluing condition of construction, elder generation's glue backward welding is the workpiece with weld-bond joint, elder generation's gluing, rear spot welding, the method that is cured at last, when adopting this method, spot welding must tackiness agent not yet gel carry out before crosslinked, the method is comparatively harsh to the requirement of spot welding, should not adopt the welding of capacitive battery welding machine and electromagnetic type welding machine, the pulse of welding current can not be really up to the mark, can not be excessively soft, meeting really up to the mark loose and pore occur around making solder joint, and is excessively soft, can make workpiece overheated, and tackiness agent viscosity is sharply reduced, cause gummosis.Elder generation's postwelding glue method, it is the workpiece with spot-weld bonding, elder generation's spot welding, and then with glue injection machine or colloid-injecting gun glue is injected and to glued joint the slit and go the method that is cured at last, elder generation's postwelding glue method, spot welding there is not particular requirement, but very harsh to the requirement of tackiness agent: 1 tackiness agent should have good flowability, in order to successfully be full of the slit on junction surface; 2. tackiness agent should not contain solvent; 3. the glue-line after solidifying should have enough toughness and shock-resistance; 4. the solidification value of glue and pressure are unsuitable too high.The present invention is weldering single-component spot-weld adhesive behind a kind of first glue take Resins, epoxy as main material production, the raw material of producing this product use has: E-44 Resins, epoxy, 501 epoxide diluents, KH one 550 coupling agents, antelope base oxirane, liquid polyamide resin, MALEIC ANHYDRIDE, m-xylene diamine, asbestos powder, prepare spot-weld adhesive take chemical reaction kettle as reaction vessel, this preparation method's advantage is: production technique is simple, use general-purpose equipment, product has the linking intensity height, good airproof performance, resistance to fatigue is good, stress distribution is even, lightweight construction, can carry out anodic oxidation, the advantages such as productivity height can be used for aluminium, the spot-weld bonding of the metallic substance such as aluminium alloy and glass reinforced plastic.
Summary of the invention
The problem to be solved in the present invention provides the method that a kind of batch prepares spot-weld adhesive, this spot-weld adhesive is take E-44 Resins, epoxy as main raw material, take raw materials such as tackifying resin, softening agent, solidifying agent as auxiliary material, produce spot-weld adhesive take chemical reaction kettle as reaction vessel, this agent has linking intensity height, good airproof performance, resistance to fatigue is good, stress distribution is even, lightweight construction, can carry out the advantages such as anodic oxidation, productivity height.The raw material of producing this product use has: liquid E-44 Resins, epoxy 50%-52%, 501 epoxide diluent 15%-17%, KH one 550 coupling agents 2%, antelope base oxirane 3%, liquid polyamide resin 8%, MALEIC ANHYDRIDE 3%, m-xylene diamine 2%, asbestos powder 15%.
The present invention can be achieved through the following technical solutions:
A kind of preparation method of spot-weld adhesive, its feature is made of following steps:
1. liquid E-44 Resins, epoxy is sent into chemical reaction kettle, start stirrer, rotating speed is 15 rev/mins, adds slowly while stirring 501 epoxide diluents, stirs to add KH one 550 coupling agents, stirring reaction 0.5 hour after 0.2 hour.
2. continue to stir, successively antelope base oxirane, liquid polyamide resin, MALEIC ANHYDRIDE, m-xylene diamine are added chemical reaction kettle, be 0.2 hour the pitch time of adding, stir, then asbestos powder is added agitator tank, stop after stirring stirring, packing gets product.
The invention has the beneficial effects as follows: the preparation method that a kind of spot-weld adhesive is provided, this preparation method's technique is simple, the use general-purpose equipment, product has linking intensity height, good airproof performance, resistance to fatigue is good, stress distribution is even, lightweight construction, can carry out the advantages such as anodic oxidation, productivity height, can be used for the spot-weld bonding of the metallic substance such as aluminium, aluminium alloy and glass reinforced plastic.
