Abstract
The invention relates to a modified asphalt hot-melt damping material for vehicles. Modified asphalt and rubber are blended; tackifying resin is added for strengthening the adhesive property of the damping material; the damping material comprises the following components in portion by weight: 100 to 200 portions of the modified asphalt, 5 to 60 portions of the rubber, 50 to 200 portions of the resin, and 250 to 800 portions of filler; and the materials are subjected to modification, rubber refining, kneading, extrusion and tabletting molding to produce the modified asphalt hot-melt damping material for the vehicles. When the modified asphalt hot-melt damping material is used on a vehicle, the modified asphalt hot-melt damping material for the vehicles is paved on a vehicle body to achieve thermal lamination by only directly using the enamel paint heating process of the vehicle body. The damping material is an excellent vibration-damping noise-reduction material and has the characteristics of wide temperature range and high damping, and the damping loss factor can reach 0.8 at a temperature of between 20 and 40 DEG C.
Description
Technical field
The present invention relates to a kind of vibration damping and noise reducing material and preparation and constructional method that is used for vehicle interior, refer in particular to a kind of modified asphalt hot-melt damping material and preparation and constructional method that is used for vehicle.This damping material has the characteristic in high damping, wide temperature territory, and hot melt adhesion can reduce noise at vehicle interior, suppresses vibration, improves vehicle riding comfort.
Background technology
Along with the develop rapidly of track traffic industry and automobile industry, in order to create a comfortable space, vibration and noise reducing has been applied to the car body and the floor of the vehicles such as automobile, train more and more with polymer damping material.Polymer damping material mainly is to utilize the visco-elasticity of macromolecular material owing to intermolecular internal friction kinetic energy to be converted to heat energy in vibration processes, thereby the amplitude of vibration is reduced.
The modified asphalt hot-melt damping material of vehicles in the market, be main organic composition mainly with high-polymer modified pitch, and improved bituminous perception temperature with this, make damping material have good high and low temperature resistance, and good toughness, ageing-resistant performance and corrosion resistance nature, have excellent sound insulation and damping capacity, vibration and noise reducing, acoustical and thermal are played in the fields such as automobile, train, aircraft, engineering machinery that can be applicable to.
The damping loss factor of general good damping material should be more than 0.4, so just has the effect of better damping noise reduction, but the hot-melt damping material that present vehicle is adopted is owing to internal friction between the molecular chain of modifying asphalt is still less than normal, still there is damping loss factor problem on the low side (generally about 0.4), the finger that just touched the mark, so the vibration and noise reducing effect is still not very good.Chinese patent (patent No. is ZL85104749.1) discloses a kind of wide temperature zone high damping hot-melt damping material that is used for automobile industry, but above-mentioned damping material shrinking percentage is 5%, damping loss factor only is about 0.3, so the vibration and noise reducing effect is not very good.Chinese patent (patent No. is 200410035402.1) discloses the another kind of SBS modified asphalt hot-melt damping material of automobile industry and preparation method thereof that is used for, the hot melt shrinking percentage of this material only is 1%, damping loss factor also only is about 0.4, and the vibration and noise reducing effect is not very good yet.Therefore necessary this is further studied.
Summary of the invention
The objective of the invention is the deficiency that exists at present modified asphalt hot-melt damping material for vehicles, research and propose a kind of high and low temperature resistance excellence, the wide temperature of high damping territory, low-shrinkage, damping material and preparation and constructional method that the hot melt bonding strength is strong.The heat-processed of this material use carbody directly is attached on car body inside, has tangible vibration and noise reducing effect.
The present invention realizes purpose of the present invention by following technology implementation scheme.A kind of modified asphalt hot-melt damping material for vehicles adopts modifying asphalt and blend rubber, adds tackifying resin again and strengthens adhesiveproperties, and the composition and the proportioning of its damping material are as follows:
100～200 parts of modifying asphalts; 5～60 parts of rubber; 50～200 parts of resins; 250～800 parts of fillers;
With above-mentioned materials through modification, refining glue, mediate, extrude, compression molding, make modified asphalt hot-melt damping material for vehicles.
Above-mentioned modifying asphalt can be one or two or more kinds a mixture of 10#, 40#, 70#, 110# bituminous, formed modifying asphalt after being one or two or more kinds the modification of mixture among SBS, EVA, APP, the CPE through asphalt modifier;
Above-mentioned resin is one or two or more kinds the mixture in petroleum resin, Gum Rosin, terpine resin, resol, the coumarone indene resin;
Above-mentioned filler is one or two or more kinds the mixture in aluminium hydroxide, barium sulfate, lime carbonate, magnesium oxide, zinc oxide, mica, the silica.
Preparation technology of the present invention may further comprise the steps:
The first step: in 160 ℃～230 ℃ asphalt modification stove, add pitch and properties-correcting agent, stir insulation and treated that properties-correcting agent was uniformly dispersed fully in 2～4 hours;
Second step: with rubber and part filler in mill mixing evenly, slice then;
The 3rd step: above-mentioned mixing rubber, modifying asphalt, resin and residue filler added together in 60 ℃～100 ℃ the kneader even discharging afterwards to be mixed;
The 4th goes on foot: the compound that stirs is sent in the forcing machine extruded, moulding is prolonged in two then roll-ins.
This modified asphalt hot-melt damping material for vehicles is directly to utilize the heating baking vanish process of car body realization heat posted to close to be laid on the car body in the use on the vehicle.
Modified asphalt hot-melt damping material of the present invention is compared over-all properties have been had and has significantly improved with other hot-melt damping material.Owing to adopted rubber and modifying asphalt blend, because it is big to have polarity in the rubber, bulky side group, increased the internal friction of molecule segment motion after the adding, improve the damping capacity of damping material, widened the use temperature territory of damping material, increased the sterically hindered of material, its damping loss factor is up to 0.8, and the use temperature scope is between-30 ℃～70 ℃; And, improved the adhesiveproperties of damping material owing to added tackifying resin.This damping material can be bonding with the car body inner tight of vehicle by hot melting way, has excellent vibration and noise reducing performance.
