Abstract
The present invention relates to adhesive, and is especially one kind of tough adhesive composition for connecting edge folding parts in automobile. The tough adhesive consists of thermoplastic resin, thermosetting resin, curing agent, promoter, diluent, oil absorbing assistant, synthetic rubber, rustproof agent, thixotropic agent, anti-ageer and stuffing in certain proportion. The preparation process includes the mixing of the components and rolling in a three-roller rolling machine to form paste. The tough adhesive has high adhesion strength and may be used in connecting thin steel sheet, etc.
Description
Technical field
The present invention relates to a kind of tackiness agent, particularly relate to a kind of toughened adhesive composition, be mainly used in automobile system
Make the bonding of middle car door, case lid, roof drainage tray flanging position.
Background technology
Body of a motor car is affected at present mostly is epoxyn with bonded adhesives, bonding stability, stopping property, stripper-resistance and environmental compatibility have much room for improvement with becoming all, all relate to the problems referred to above as Chinese patent application 99815167-X and 98802708.9 files, but it is undesirable, the spot welding that can not replace body of a motor car sheet metal material flanging and docking site as its bonding strength fully is connected, and is difficult for making the about surfacing of vehicle body smooth, attractive in appearance and suitable.
Summary of the invention
The objective of the invention is provides a kind of toughened adhesive composition both to need not welding behind the adhesive member in vehicle body is made at the above-mentioned problems in the prior art, and shearing resistance and peel strength height, plate is indeformable, tolerate P-levels liquid and water flushing, high-low temperature resistant.
Technical scheme of the present invention is characterized in that comprising as being scattered in thermoplastic resin polyvinyl chloride or the heat-curable urethane modified bisphenol A type Resins, epoxy of vinyl chloride-vinyl acetate copolymer weight proportion 30-40% and the composition of poly ethyldiol modified bisphenol A epoxide resin and bisphenol A type epoxy resin that fusing point in the Resins, epoxy is lower than the weight proportion 15-20% of resin solidification temperature after the heat, the curing agent dicyandiamide of weight proportion 4-5% or sebacic dihydrazide, the curing catalyst alkyl substituted imidazole of weight proportion 1-2% or modification guanylurea, the synthetic rubber nitrile (HTBN) of weight proportion 3-4%, oil suction auxiliary agent glycol ether or the polyglycol type epoxy resins of weight proportion 3-4%, the thinner dioctyl phthalate (DOP) of weight proportion 15-20% or dibutyl phthalate or benzyl glycidyl ether, weight proportion 0.07% anti-aging agent 2,6 ditertiary butyl p cresol, weight proportion 15-20% weighting agent is through the glass microballon of coupling agent surface-treated lime carbonate and granularity 0.25-0.3mm, the rust-preventive agent zinc chromate of the thixotropic agent aerosil of weight proportion 1-2% or hydrogenated castor oil or organobentonite and weight proportion 0.2-05%.
Above-mentioned materials are commodity, and the domestic market is in stockit is available.
The heating of above-mentioned thermoplastic resin can plastify during approximately to 160 ℃, dissolves each other with above-mentioned other component, forms through the tough gonosome of glue, and glue hardness is reduced, and toughness and bonding strength increase, but if proportioning greater than 20%, its bonding strength can reduce; If be lower than 15%, then easily crisp after the adhesive curing, poor toughness can not be born big external stress effect.
Above-mentioned thermosetting epoxy resin can provide fabulous bonding strength and thermotolerance for this product.
Above-mentioned solidifying agent materials are hot active material, help above-mentioned epoxy resin thermosetting.Proportioning is lower than 4%, and its bonding strength can fully not solidified and influence to this product, if be higher than 5%, then is unfavorable for its package stability.
Above-mentioned oil suction auxiliary agent can decompose and absorbs the slushing oil treat on the sticking thing, to improve bonding strength.
Above-mentioned filler loading is lower than 15%, and then its toughness and manufacturability are poor, is higher than 20%, and then poor toughness is easily split.Glass granules wherein such as has at phasic property, can make unstressed high concentration phenomenon in this product, prevents stress cracking and makes its flowability, good manufacturability.
Get the raw materials ready by said ratio, earlier thermosetting epoxy resin, thinner, synthetic rubber are mixed by proportioning, again by proportioning adding other component except that granulated glass sphere, be mixed to no pulverulence, roll into even paste at three-roller then, add above-mentioned granulated glass sphere by said ratio, de-bubbled is 30 minutes in a vacuum, just can be made into product.
Beneficial effect of the present invention, as mentioned above, its parameter is after 160 ℃ heating was solidified in 30 minutes down, and measured shearing resistance is washed greater than 100N/25mm, hardness 80 ± 5A, tolerate P-levels liquid and water greater than 15Mpa, peel strength and do not influence practicality under-30 ℃～80 ℃.
