Description
Technical field
The present invention relates to car damping technical field more particularly to a kind of magnetic attraction damping sheets and its magnetizer.
Background technology
Shock material is widely used in weakening in automobile application vibration and the sound of road noise and engine.
For damping material, viscoelastic material is preferred.With the relevant damping effect of energy that is consumed in viscoelastic material with
It the increase of the Young amount of touching and the loss factor of viscoelastic material and increases.Certainly, it also as the deformation that material is born and
Increase.Some materials have high loss factor but the low Young amount of touching, and provide metallic plate limited damping, other materials
Equally it is not very good as damped part with the high Young amount of touching but relatively low loss factor (for example, rubber).It is good
Good damping material provides the compromise between the Young amount of touching and loss factor.
At present, most of automobiles use traditional pitch damping sheet, and pitch is a kind of organic substance as a form of gel of brownish black, bag
Include four kinds of bitumen, asphalt, shale tar pitch and coal tar asphalt etc..In pitch and its flue gas main component for phenols,
Main component is phenols, compound, anthracene, naphthalene, pyridine etc. to mucocutaneous tool irritation, drip in compound, pitch and its flue gas
Blue or green damping sheet has stronger carcinogenesis to people, this can endanger the health of personnel, therefore how reduce these harmful components
Influence is the eternal problem that technical staff faces.
Through retrieval, Chinese patent application, publication number：CN105602233A, publication date：2016.05.25, one kind is disclosed
Economic and environment-friendly high damping properties damping sheet, including following raw material：Polyurethane elastomer, flyash, mica, hydrogenation C5 oil trees
Fat, glass fibre, carbon black, antiaging agent, antioxidant, mass ratio are：200-250；410-500；400-475； 40-80；
4-10；20-100；5；5, which, as functional damping filler, is turned waste into wealth using waste coal ash, and uses environmental protection
Polyurethane replace harmful pitch, energy-saving and emission-reduction, ecological, environmental protective, production cost is low, and the cycle is short, production technology science, makes
Convenient, product has good damping, deadening, and damped coefficient is high, and ageing resistance ability is strong.But polyurethane, which is block, to be total to
Polymers and other materials such as mica (hard section), Petropols (soft segment) etc. combine force difference, are easily layered and cause effectively to use
Short life.
The content of the invention
1. technical problems to be solved by the inivention
For existing in the prior art, pitch class damping sheet is although at low cost but pernicious gas is more, substitute is of high cost, has
The problem of effect service life is poor and is dehydrated not in time, the present invention provides a kind of magnetic attraction damping sheet and its magnetizers.It
It is set by pressing plate and damping sheet surface moisture is squeezed into water outlet, and reduce asphalt content, optimization in damping board mixture in batches
Other dispensing processing methods achieve the purpose that reduce damping sheet application risk.

Asphalt modifier and/or softening agent can add respectively in blend step and step (2), to play its effect as far as possible, keep away
Exempt from after all being applied in certain step, decreased effectiveness.
Embodiment 8
The magnetic attraction damping sheet of the present embodiment, basic ingredients are different and the improvement is that with embodiment 5：
The making step of ultra-fine light calcium carbonate powder is：
Step 1: reactant generates：Sodium carbonate and calcium chloride are subjected to metathesis reaction generation precipitation of calcium carbonate, filtered
Calcium carbonate coarse powder；
Step 2: mixing：Calcium carbonate coarse powder, friction oil and water are sufficiently mixed as lyophilized presoma；The water consumption is added to be
3 times of coarse powder gross weight；
It is Step 3: quick-frozen：Lyophilized presoma is tiled into mold, thickness 5.0cm, inserts -40 DEG C or so quick freezing repository speed
It is frozen into bulk；
It is Step 4: lyophilized：Lump material push-in dry storehouse is carried out being lyophilized into cellular block of material；The same mica of lyophilized technique
Powder；
Step 5: fine grinding：Cellular block of material is sent into grinder to carry out being finely ground to ultra-fine light calcium carbonate powder.
The processing method of the present embodiment magnetic attraction damping sheet, step are：
(1) pitch softens：AH-80 pitches input kneader is warming up to 100 DEG C or so softenings, stirs into fluid；
(2) stir：By remaining EVA input kneader stirrings；
(3) fiber crushes：In step (1) whipping process, input kneader continues to stir after flaxen fiber is crushed to 10 mesh
20 minutes；
(4) calcium powder adds in：Magnetic powder, mica powder and lyophilized ultra-fine light calcium carbonate powder input kneader obtained are continued into 5 points of stirring
Clock or so；
(5) squeeze out：After stirring, it is transferred to extruder and squeezes out and generate damping fin with to roll tablet.
Magnetic attraction damping sheet made from the present embodiment, entire lyophilized technique process only 2 it is small when or so, production cost will not
How much is raising, moreover, after pitch infiltration into microporous, matches the mica powder greatly improved, light calcium carbonate powder also has one to the smell of pitch
The slow releasing function (pitch part infiltration into microporous and Wei Keng) of kind avoids batch in the pernicious gas short time from generating and generated to human body
Harm.
Schematically the present invention and embodiments thereof are described above, this describes no restricted, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited thereto.So if common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
