Abstract
The invention is a kind of magnetic damp board and the manufacturing method, which belongs to compound material technique field. It is used for resolve the prefabrication problem of automobile coating damp glue line. The technique project is: it is made up of asphalt, regenerative rubber powder, random polypropylene, solvent naphtha, ferromagnet, and fillers. The shape of the board like a flake, one surface is smooth, the other surface has diamond shallow slots. The invention overcomes the default of traditional high pressure painting method. The thickness of the damp board can be controlled precisely, the board combines with the metal base board tightly, the method is simple and easy to realize. The product can decreases the vibration and noise when the car in moving greatly.
Description
Technical field
The present invention relates to a kind of vibration proof material and preparation method, damping sheet and preparation method especially for Motor vehicles minimizing covering vibration and noise belong to technical field of composite materials.
Background technology
Automobile is when advancing, because factors such as the work of engine, Uneven road all can cause vibration, vibrate the metal skin that is delivered to vehicle body by vehicle frame, metal skin changes this vibrational energy into noise, and noise can make the passenger feel very ill, and the situation of motorbus is particularly serious.On structure, the steel plate that automobile skin uses is very thin, about about 1mm, needs the place of covering a lot of again on the automobile, and the ratio of covering area and covering thickness of slab is very big, and this structure is easy to produce and transmitting vibrations.For eliminating this disadvantage, people weaken by every possible means or block this vibration transfer chain.In numerous solutions, a kind of scheme is to adopt matrix material to come the alternative metals covering, discloses a kind of material that can be used as automobile skin for No. 92114241 as Chinese patent, and it is the multilayer materials of a kind of wire, band reinforced plastics.Even another scheme then is to allow metal skin be shaken also be difficult for producing noise, we can say that this is to solve the effective preferred plan of sound pollution.At present, general terms of settlement is the physical properties that changes covering, and it is the composite material skin of base material that the covering that is about to pure metal is changed into the metal, and concrete way is the internal surface composite damping glue-line at metal skin.This way is not only and is allowed the covering thickening, the most important thing is that its physical property produces very big change thus.Because the damping glue-line contains a large amount of viscoelastic materials, these visco-elastic materials are under the condition of external force vibration, and the continuous displacement of its molecule also is converted into heat energy by this internal friction with vibrational energy, and at this moment, noise will reduce significantly.The method of high pressure painting is generally used in the construction of damping glue-line, and the heavy-gravity damping glue is sprayed on the automobile skin.But the problem that exists is, this heavy-gravity damping glue construction is to be difficult to its thickness of control, and the thickness of composite bed directly influences its damping capacity, on metal skin, how to obtain thickness accurately, in conjunction with firm damping glue-line, be the key of whole problem.
Summary of the invention
Technical problem to be solved by this invention is: overcome the defective of above-mentioned prior art and a kind of ready-formed magnetic damping plate be provided, it can more easily on the motor vehicle covering, realize thickness accurately controlled, in conjunction with firm damping glue-line.Another technical problem to be solved by this invention provides the preparation method of magnetic damping plate.
The alleged problem of the present invention is solved by following technical scheme:
A kind of magnetic damping plate, its special feature is: it adopts damping material to be prefabricated into the sheet damping sheet, and described damping material is formed (weight percent) by following raw material:
Petroleum pitch 25～35%
Regnerated rubber powder 3～8%
Atactic Polypropelene 3～8%
Solvent oil 2～4%
Magnetic iron powder 25～35%
The filler surplus.
Above-mentioned magnetic damping plate, described filler are the mixed fillers of talcum powder, asbestos powder, wollastonite powder, mica powder composition.
Above-mentioned magnetic damping plate, its profile are slick planes simultaneously in the form of sheets, and another side has the rhombus shallow trench, and thickness of slab is 1.5～3 millimeters, 0.5 millimeter of gash depth.
Described magnetic damping plate adopts following operation preparation:
A. prepare burden, take by weighing the raw material following (weight percent) of magnetic damping plate:
Petroleum pitch 25～35%
Regnerated rubber powder 3～8%
Atactic Polypropelene 3～8%
Solvent oil 2～4%
Magnetic iron powder 25～35%
The filler surplus;
B. heating mixes: be heated to 180～200 ℃ of fusing petroleum pitch, drop into regnerated rubber powder, Atactic Polypropelene, throw in while stirring, three kinds of raw materials are mixed, and cooling then is when temperature reduces to 100～120 when spending, drop into solvent oil, magnetic iron powder, mixed fillers, continue to stir, mix, become micelle until each raw material;
C. compressing tablet: the damping micelle that makes is inserted tabletting machine, and to be pressed into one side with mould be the light face by setting thickness, and another wears the sheet damping sheet of diamond pattern shallow trench;
D. cutting: the irregular magneticdamping workprint of profile is cut into the specified shape and size of user.
E. magnetize: magnetic damping plate is magnetized on magnet charger.
Magnetic damping plate of the present invention, the high pressure painting that has overcome the traditional technology use carries out the drawback that the damping glue-line is constructed to vehicle skin, it can utilize the magnetic of damping sheet that it is attached to the metal skin internal surface easily, when being heated (as baking vanish) along with covering, offset plate and the steel plate formation composite bed that tightly bonds.Adopt the constructional method of this damping sheet simple and easy to do, the accurately control in batch is prefabricated of damping sheet thickness, damping sheet combine firmly with metal substrate.The results showed, the noise and vibration that the damping glue-line that adopts magnetic damping plate to constitute can reduce vehicle significantly to be produced when advancing, every performance index meet or exceed the level of former spraying coating process.In addition, preparation method's technology of magnetic damping plate is simple, the equipment input cost is low, easily realizes producing in batches, for promoting the use of of magnetic damping plate created advantageous conditions.
