Description
Technical field
The invention belongs to technical field of polymer materials, and in particular to a kind of economic and environment-friendly high damping properties damping sheet and
Preparation method.
Background technology
Flyash is larger one of the industrial residue of the current discharge capacity in China, and China's year bed drain purge is up to 30,000,000 t at this stage,
With the development of power industry, the flyash discharge capacity of coal-burning power plant increases year by year.If a large amount of flyash is untreated, just
Airborne dust is will produce, air is polluted；River can be caused to silt up if being discharged into water system, and toxic chemical substance therein can also to human body and
Biology causes damages.Therefore, the processing of flyash and Utilizing question cause people widely to pay attention to.Therefore state key is from following
5 aspects clearly encourage support policy, include mainly:It encourages to carry out high added value to flyash and large dosage utilizes；Support hair
Open up aluminous fly-ash extraction aluminium oxide and Related product；Support the flyash in great mixed amount novel wall material of Development Technology maturation；
It encourages to substitute clay progress dispensing using flyash as cement mixture and in raw material；Encouragement is made commodity using flyash and is mixed
Solidifying soil admixture etc..
Currently, most of automobiles use traditional pitch damping sheet, pitch is a kind of organic substance as a form of gel of brownish black, packet
Include four kinds of bitumen, asphalt, shale tar pitch and coal tar asphalt etc..In pitch and its flue gas main component be phenols,
Main component is phenols, compound, anthracene, naphthalene, pyridine etc. to mucocutaneous tool irritation, drip in compound, pitch and its flue gas
Green damping sheet has stronger carcinogenesis to people, this can endanger the health of personnel, it is therefore desirable to develop it is a kind of without using pitch,
Flyash can be used for the damping sheet of damping.
Invention content
To solve the above problems, the invention discloses a kind of economic and environment-friendly high damping properties damping sheets and its preparation side
Method, bituminous material, damping damping be not good.
In order to achieve the above objectives, technical scheme is as follows：
A kind of economic and environment-friendly high damping properties damping sheet, it is characterised in that：Including following raw material：Polyurethane elastomer,
Flyash, mica plus hydrogen C5 Petropols, glass fibre, carbon black, antiaging agent, antioxidant.
Preferably, the polyurethane elastomer, flyash, mica plus hydrogen C5 Petropols, glass fibre, carbon black, anti-old
Agent, antioxidant mass ratio be：200-250；410-500；400-475；40-80；4-10；20-100；5；5.
A kind of preparation method of economic and environment-friendly high damping properties damping sheet, includes the following steps：
（1）Vacuum kneader is opened, is warming up to 160-200 DEG C,
（2）Start vacuum kneader, adds polyurethane elastomer, antioxidant, age resister plus hydrogen C5 Petropols, stir
It mixes 25-30 minutes,
（3）Temperature is reduced to 140-155 DEG C, and flyash is added, and stirs 10-20 minutes,
（4）Mica, carbon black, glass fibre are added, 55-60min is stirred, keeps pressure 4.5-5MPa,
（5）It is squeezed out using screw extruder, opens calendering, cross cutting, obtain high damping properties damping sheet.
A kind of economic and environment-friendly high damping properties damping sheet of the present invention, using the high performance polyurethane elasticity of environmental protection
Body as functional filler, adds hydrogen C5 Petropols as tackifier as function matrix, flyash and mica, glass fibre and
Carbon black is as supporting material, and conduction oil is as softening medium, and the feature of environmental protection is good, damping is strong.
Petropols are a kind of chemical products newly developed in recent years, and since it has, cheap, compatibility is good, fusing point
The advantages that low, water-fast, resistance to ethyl alcohol and chemicals, can be widely used for a variety of industries such as rubber, adhesive, coating, papermaking, ink and
Field, Petropols production application are preferably at most C9 Petropols and C5 Petropols, and wherein C5 Petropols are bonded with its stripping
Intensity is high, fast viscosity is good, adhesive property is stable, melt viscosity is appropriate, heat-resist, good with the compatibility of high polymer matrix, and
The features such as price is low starts gradually to replace natural resin tackifiers（Rosin and terpene resin）, C5 Petropols are due to containing not
It is saturated double bond, it is heated to aoxidize, there is certain smell, adds feature of the hydrogen C5 Petropols in hot melt adhesive, due to not depositing
In unsaturated double-bond, there is no smell after heated, it is more environmentally-friendly, and good fluidity, the wetability of material of main part can be improved, viscosity
It is good, there are initial cohesiveness outstanding, excellent ageing resistance of light color, transparent, low smelly, low volatile.
Flyash is larger one of the industrial residue of the current discharge capacity in China, and a large amount of flyash is untreated, just will produce
Airborne dust pollutes air；River can be caused to silt up if being discharged into water system, and toxic chemical substance therein can also make human body and biology
At harm.Therefore, the processing of flyash and Utilizing question cause people extensive note that the present invention is during making damping sheet
Flyash is added, using the special honeycomb structure of flyash, when by extraneous stress, can phase mutual friction, disappear
Energy consumption improves damping capacity, to realize waste recycling, damping sheet used by automobile factory at present, it is common to use carbon
For sour calcium as filler, flyash is in contrast, more economic benefit, the feature of environmental protection, damping.
Polyurethane elastomer be reacted with isocyanates by polyalcohol generate using carbamate as its feature chain link
A major class compound, polyurethane elastomer is block copolymer, it is made of flexible soft segment and rigid hard section, and flexible soft segment can
To be polyether polyol, polyester polyol, polyolefin polyhydric alcohol etc., rigid hard section is carbamate, urea groups, phenyl ring, contracting
The rigid radicals such as two ureas result in microphase-separated since the thermodynamics of soft segment and hard section is incompatible, and polyurethane is because its is unique
Structure can be used as best one of damping material, when it is by external alternate stress, by between macromolecular chain and inside chain
Friction convert vibrational energy to thermal energy and consume, to reach good damping.
Age resister of the present invention is benzotriazole ultraviolet absorber aqueous dispersion, salicylic acid esters, hindered amine
The one of which of class light stabilizer aqueous dispersion, antioxidant are four (methylene-(3,5- di-t-butyl -4- hydrogen cinnamates))
Methane.
The present invention is in preparation process, step（4）Stirring is sealed to mixture, can stir evenly, without dead angle, pinch
Efficient, raising damping capacity is closed, damping sheet is fuses when heated without solidification, and the performance requirement of general damping plate, which is 20 DEG C, is
0.13, the damped coefficient of economic and environment-friendly high damping properties damping sheet of the present invention can reach 0.25, improve by about one time.
The beneficial effects of the invention are as follows
A kind of economic and environment-friendly high damping properties damping sheet of the present invention, using waste coal ash as functional
Damping filler, turns waste into wealth, and replaces harmful pitch, energy-saving and emission-reduction, ecological, environmental protective, production cost using the polyurethane of environmental protection
Low, the period is short, and production technology science, choice materials are easy to make, and product has good damping, deadening, damped coefficient
Height, ageing resistance ability is strong, and service life is long, and applicability is wide, is conducive to large-scale industrial production.
