Description
Technical field
The invention belongs to technical field of adhesive, relate to a kind of Solvent Adhesive (adhesive) of use heat reacting resin, be applied to automobile especially; Motorcycle, the brake(-holder) block of industrial machinery (brake facing), clutch coupling; Comprise metal and metal, the matrix material of metal and fortifying fibre and resin, metal and resin or matrix material and matrix material; Especially the short period of time of liner (motor, the drum brake sheet of industrial machinery) that is applicable to aluminum casting is bonding.
Background technology
Liner and friction materials, such as, the drum-type brake pad of motorcycle is generally by liner (aluminium; Duraluminum), adhesive linkage and friction materials constitute, friction materials; In the liner method, the Solvent Adhesive of heat reactivity resin sprays or is coated in friction materials or liner, after the oven dry through adhesive; Through the mode of heating and pressurizing, make friction materials be fixed on the method (the Japanese documentation spy opens 2011-231875) on the liner.Tackiness agent can be expanded in bond locations comprehensively for this method, brings into play strong bond strength.
On the other hand, in aluminium liner bonding, beyond the bonding intensity of force, also elasticity of demand.Particularly the drum-type brake pad of motorcycle if elasticity is too little, can cause the problem that reduces bounding force.To such problem, the tackiness agent that the drum-type brake pad of motorcycle is used generally has elasticity, and after the surface of aluminium handles with phosphoric acid salt etc., sprays or applies with primer.The adhesive power with aluminium is strengthened in such processing.
The above-mentioned friction materials and the fixing means of liner use Solvent Adhesive, such as the method as liner and the friction materials of bonding brake facing, are coated in after the processing such as phosphoric acid salt by tackiness agent with jet pipe or atomizer, scribble the steel plate of primer.Afterwards, adopt seasoning or the furnace drying method of short period of time, let the solvent evaporates of tackiness agent.Afterwards, under the condition of heating and pressurizing, be bonded together liner and friction materials forcefully.
Brake facing tackiness agent has till now all used to comprise toluene the solvent that YLENE etc. are harmful.Perhaps the heating and pressurizing condition is more than 40 minutes.
Summary of the invention
The objective of the invention is for addressing the above problem, and short period of time adherent tackiness agent of a kind of liner (motor, the drum brake sheet of industrial machinery) that is specially adapted to aluminum casting that proposes and using method thereof.The present invention does not use hazardous solvent, and shortens in heating and pressurizing time to 20 minute.
Main technical schemes of the present invention: a kind of tackiness agent; It is characterized in that this tackiness agent is the Solvent Adhesive constituent; Comprise: the paracril of 8-20 weight part or styrene-butadiene rubber(SBR), the resol liquid of 10-35 weight part, and the reagent of 2-6 weight part.
Usually, like aforesaid adhesive compsns, wherein, the solids content of resol liquid is 0.3-1.6 with the ratio of the weight part of paracril or styrene-butadiene rubber(SBR).
Like aforesaid adhesive compsns, reagent wherein comprises silica gel, carbon black, silane coupling agent, the flowers of zinc, lime carbonate, permanent white, DPPD, BHT, BF
9-MEA, or above-mentioned combination.
Like aforesaid adhesive compsns, further comprise the solvent that is less than or equal to 160 weight parts.
Like aforesaid adhesive compsns, solvent wherein comprises butanone, vinyl acetic monomer, dimethylcarbinol, or above-mentioned combination.
Adhesive compsns of the present invention is used in and contains aluminium, duraluminum, and perhaps bond properties requires the material near aluminium.
Adhesive compsns of the present invention, bonding through the mode of heating and pressurizing.
Usually, said tackiness agent is before bonding
,Dry.
Said tackiness agent through the heating and pressurizing more than 200 degrees centigrade reaction, can guarantee bond strength and bond area with interior in 20 minutes.
Tackiness agent of the present invention utilizes flowing of Solvent Adhesive can let tackiness agent be coated in bond locations comprehensively, reaches the equalization of bond area and the performance of the bounding force of brute force.And, the toluene that Solvent Adhesive contained that does not have existing brake facing to use, YLENE.Do not have the glue-line of powder adhesive blocked up, inhomogeneous yet, perhaps can not be coated in liner comprehensively, can not be bonding, and the gas that produces during high temperature sclerous reaction in advance can not discharge and the bubble that brings can not reach problems such as requirement effect by bounding force.Use the aforesaid method of Solvent Adhesive, can satisfy bond area and high-intensity specification simultaneously, be applicable to clutch coupling, the application of brake facing.
The present invention uses harmless solvents such as butanone and vinyl acetic monomer, shortens in heating and pressurizing time to 20 minute.
The mode of practical implementation
Below, through implementing example the present invention is described, but the present invention is not confined to implement example.
Brake facing liner used herein comprises, as long as, the friction materials of being stated below ability is bonding, not special restriction.
The material of liner can be, aluminium contains the sintering metal of aluminium, duraluminum, and bond properties requires the resin near aluminium, the matrix material of metal and resin or fortifying fibre and resin.
The tackiness agent that brake facing is used (binder solution), be coated in friction materials or liner after, need the oven dry.Because the boiling point of solvent is the 50-120 degree, so bake out temperature is normal temperature (15-35 degree), perhaps 70-120 degree.
Liner, friction materials can sprayed or be coated in to the coating of tackiness agent.
Tackiness agent after the coating, because tackiness agent has comprised solvent, than being easier to be penetrated in the friction materials, perhaps is penetrated into primer, and perhaps the processing layer of steel plate can be guaranteed original bond strength more.
Friction materials used in the present invention, as long as can let the brake system of automobile, the material of the damping force of bringing into normal play, not special restriction.
Concrete, as to generally know that except use material, such as the semi-metal fiber, the copper fiber; Brass fiber, polypropylene fibre, fibrous matters such as carbon fibre also have; Resol, epoxy, the matrix material that the thermosetting resin of melamine resin etc. forms.
And the cooperation ratio of above-mentioned materials according to the difference of rubbing characteristics, is suitably regulated.
