Abstract
The invention relates to a preparation method of a damping material used for installing a draught fan. The preparation method comprises the following steps: 1, putting nanometer carbon black, silica sol and addition agents into waterborne polyurethane latex, conducting ultrasonic treatment, and obtaining composite emulsion for standby application; 2, conducting mixing, grinding and dispersing on expanded vermiculite, cristobalite, bentonite and 3-phenyl-2-propyl acrylate for 2-2.5 h, mixing the obtained materials with other residual materials, stirring the mixture evenly and sufficiently, putting the mixture into a twin-screw extruder, conducting prilling by fusing and extrusion at the temperature ranging from 180 DEG C to 190 DEG C, and obtaining modified master batches; 3, putting the modified master batches into a screw extruder for being fused, spraying the flux out through a melting-spraying die head spinning orifice at the temperature ranging from 230 DEG C to 250 DEG C, stretching the flux under the effect of high-speed hot air flow, putting the flux into a receiving device, and after the composite emulsion is solidified and dried completely, obtaining the finished damping material. The phenolic resin damping material wrapped by expanded vermiculite-polyurethane composite emulsion which is obtained through preparation is low in mass, small in thickness and quite good in damping effect.

Background technology
Now, along with the continuous acceleration of urbanization, a large amount of construction of Highrise buildings, supporting change the noise pollution that wind exhaust system brings and also become more and more serious.Fixing blower fan operationally can vibrate, thus causes low frequency noise, and long term operation is lived in the environment of low-frequency noise, can bring adverse influence to the health of human body, the mental status and mood.Simultaneously long-term vibration can bring fatigue damage to building, has a strong impact on the structural safety of buildings.In order to effectively reduce vibration, cut off noise, common settling mode uses damping material.Existing damping material is generally cement concrete, rubber etc.The practical effect of these damping materials is not very well, and therefore common terms of settlement strengthens the thickness of damping material, and make vibration-proof structure complicated.The problem caused like this is that damping material quality is overweight, high cost, and installation process is very inconvenient.
Summary of the invention
For the deficiency of current material, the object of the present invention is to provide the coated resol damping material of a kind of expanded vermiculite-urethane composite emulsion.This material has larger specific surface area, and in structure, comparatively traditional material is more tight, and noise reduction is obvious.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of preparation method of assembling damping material, described damping material is made up of the raw material of following weight part: resol 52-62 part, expanded vermiculite 20-25 part, polystyrene foamed plastics 6-8 part, cinnamic acid propyl ester 4-6 part, nano carbon black 1-2 part, Bornyl acetate 8-16 part, 2-Natvosol 2-5 part, diazolones 0.2-0.6 part, cristobalite 2-5 part, solid content is silicon dioxide gel 2-3 part of 10-15%, 100-200 order wilkinite 20-24 part, solid content is aqueous polyurethane emulsion 10-12 part of 8-10%, collegen filament 10-20 part, waste wool felt 20-30 part, auxiliary agent 2-5 part etc.,
Described expanded vermiculite doubly forms through 1000-1200 DEG C of high-temperature roasting enlarged volume 15-25 the particulate matter that inside has countless tiny thin layer hole after being pulverized by vermiculite;
Described collegen filament prepare through pretreated useless leather by finite concentration defibrination in paste roller mill;
Described auxiliary agent is made up of the raw material of following weight part: 400-500 order fine hair powder 1-2, sodium cetanesulfonate 0.5-0.6, propylene glycol 3-5, solid content are zirconia sol 4-5, nano zine oxide 0.6-0.8, the water 10-12 of 15-20%, preparation method is: first drop in water by propylene glycol, sodium cetanesulfonate, be stirred to after material dissolves dispersion completely, add other leftover materials again, high-speed stirring is dispersed in the solution to fine hair powder, nano zine oxide, to obtain final product;
The preparation method of this damping material is as follows:
(1) first nanometer carbon black, silicon dioxide gel, auxiliary agent are dropped into together in aqueous polyurethane emulsion, supersound process 50-60min, make material dispersed in emulsion, gained composite emulsion is for subsequent use;
(2) expanded vermiculite, cristobalite and wilkinite and cinnamic acid propyl ester mixed grinding are disperseed 2-2.5h, gained material mixes with other leftover materials, stir in rear input twin screw extruder and melt extrude granulation at 180-190 DEG C of temperature, obtain modified master batch;
(3) modified master batch of step (2) gained is dropped into melting at 180-200 DEG C in screw extrusion press, melt is the meltblown beam orifice ejection of 230-250 DEG C through temperature, and stretch under the high velocity, hot air stream effect of 250-280 DEG C laggard enter receiving trap, being gathered on the reception device after net until fiber yarn uniformly sprays in silk screen by composite emulsion prepared by step (1), and emulsion to be composite gets product after solidifying drying completely damping material.
Preferably, the solid content of described zirconia sol is 19%.
Preferably, the solid content of described aqueous polyurethane emulsion is 9%.
Beneficial effect of the present invention:
