Description
Technical field
The invention belongs to technical field of polymer materials, be specifically related to high damping properties damping sheet of a kind of economic environmental protection and preparation method thereof.
Background technology
Flyash is one of industrial residue that the current discharge capacity of China is larger, and China present stage, bed drain purge year has reached 3,000 ten thousand t, and along 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 does not add processing, will produce airborne dust, atmosphere pollution; Can cause river to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology. Therefore, the disposal and utilization problem of flyash causes that people note widely. Therefore state key is clearly encouraged support policy from following 5 aspects, mainly comprises: encourage flyash to carry out high added value and large volume utilization; Support development aluminous fly-ash to extract aluminium oxide and Related product; Support the flyash in great mixed amount novel wall material of Development Technology maturation; Encouragement utilizes flyash to substitute clay as cement mixture and in raw material and prepares burden; Encouragement utilizes flyash to make commerical ready-mixed concrete admixture etc.
At present, most of automobiles adopt traditional pitch damping sheet, and pitch is the organic material as a form of gel of a kind of brownish black, comprises four kinds of bitumen, asphalt, shale tar pitch and coal tar asphaltes etc. In pitch and flue gas thereof, main component is that in phenols, compound, pitch and flue gas thereof, main component is that phenols, compound, anthracene, naphthalene, pyridine etc. are to mucocutaneous tool excitant, pitch damping sheet has stronger carcinogenesis to people, this can endanger personnel's health, therefore need to develop a kind of do not use pitch, can be by flyash the damping sheet for damping.
Summary of the invention
For addressing the above problem, the invention discloses high damping properties damping sheet of a kind of economic environmental protection and preparation method thereof, not bituminous material, damping damping is good.
For achieving the above object, technical scheme of the present invention is as follows:
A high damping properties damping sheet for economic environmental protection, is characterized in that: comprise following raw material: polyurethane elastomer, flyash, mica, hydrogenation C5 Petropols, glass fibre, carbon black, antiaging agent, antioxidant.
Preferably, the mass ratio of described polyurethane elastomer, flyash, mica, hydrogenation C5 Petropols, glass fibre, carbon black, antiaging agent, antioxidant is: 200-250; 410-500; 400-475; 40-80; 4-10; 20-100; 5; 5.
A preparation method for the high damping properties damping sheet of economic environmental protection, comprises the following steps:
(1) open vacuum kneader, be warmed up to 160-200 DEG C,
(2) start vacuum kneader, add polyurethane elastomer, antioxidant, age resister, hydrogenation C5 Petropols, stir 25-30 minute,
(3) temperature is reduced to 140-155 DEG C, adds flyash, stirs 10-20 minute,
(4) add again mica, carbon black, glass fibre, stir 55-60min, keep pressure 4.5-5MPa,
(5) utilize screw extruder to extrude, open calendering, cross cutting, obtain high damping properties damping sheet.
The high damping properties damping sheet of a kind of economic environmental protection of the present invention, adopt the high-performance polyurethane elastomer of environmental protection as function matrix, flyash and mica are as functional filler, hydrogenation C5 Petropols are as tackifier, glass fibre and carbon black are as supporting material, 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, because it has cheap, compatibility is good, fusing point is low, water-fast, the advantages such as resistance to ethanol and chemicals, can be widely used in rubber, adhesive, coating, papermaking, the multiple industry such as ink and field, Petropols production application is at most C9 Petropols and C5 Petropols, wherein to peel off adhesive strength with it high for C5 Petropols, fast viscosity is good, adhesive property is stable, melt viscosity appropriateness, good heat resistance, good with the compatibility of high polymer matrix, and the feature such as price is low, start progressively to replace natural resin tackifier (rosin and terpene resin), C5 Petropols are owing to containing unsaturated double-bond, be heated and can be oxidized, have certain smell, the feature of hydrogenation C5 Petropols in PUR, owing to there not being unsaturated double-bond, after being heated, there is no smell, environmental protection more, and good fluidity, can improve the wetability of material of main part, viscosity is good, has outstanding initial cohesiveness, good ageing resistance, of light color, transparent, low smelly, low volatile.
Flyash is one of industrial residue that the current discharge capacity of China is larger, and a large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; Can cause river to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology. Therefore, the disposal and utilization problem of flyash causes that people note widely, and the present invention adds flyash in making damping sheet process, utilize the special alveolate texture of flyash, in being subject to extraneous stress, can phase mutual friction, consumed energy, improve damping capacity, thereby realize waste recycling, the damping sheet that automobile factory adopts at present, generally uses calcium carbonate as filler, flyash and its contrast, have more economic benefit, the feature of environmental protection, damping.
Polyurethane elastomer is the large compounds using carbamate as its feature chain link being generated by polyalcohol and isocyanate reaction, polyurethane elastomer is block copolymer, it is made up of soft section of flexibility and the hard section of rigidity, flexible soft section can be PPG, PEPA, polyolefin polyhydric alcohol etc., the hard section of rigidity is carbamate, urea groups, phenyl ring, the rigid radicals such as biuret, due to the incompatible microphase-separated that caused of thermodynamics of soft section and hard section, polyurethane is because its unique structure, can be used as one of best damping material, in the time that it is subject to outside alternate stress, by the friction of between macromolecular chain and chain inside, vibrational energy being converted into heat energy consumes, thereby reach good damping.
Age resister of the present invention is the wherein one of benzotriazole ultraviolet absorber aqueous dispersion, salicylate class, hindered amine light stabilizer aqueous dispersion, antioxidant is four (methylene-(3,5-di-t-butyl-4-hydrogen cinnamate)) methane.
The present invention is in preparation process, step (4) seals stirring to mixture, can stir, without dead angle, mediate efficiency high, improve damping capacity, when damping sheet is heated, melt and do not solidify, it is 0.13 that the performance requirement of general damping plate is 20 DEG C, and the damped coefficient of the high damping properties damping sheet of economic environmental protection of the present invention can reach 0.25, improves nearly one times.
The invention has the beneficial effects as follows
The high damping properties damping sheet of a kind of economic environmental protection of the present invention, adopts discarded object flyash as functional damping filler, turns waste into wealth, and the polyurethane that uses environmental protection replaces harmful pitch, energy-saving and emission-reduction, ecological, environmental protective, production cost is low, and the cycle is short, production technology science, choice materials, easy to make, product has good damping, deadening, damped coefficient is high, and ageing resistance ability is strong, long service life, applicability is wide, is conducive to mass industrialized production.
