Abstract
The invention discloses a soundproof wax for an automobile. The soundproof wax is composed of the following components in percentage by weight: 15-40% of petroleum asphalt, 25-45% of a solvent, 15-40% of filler, 2-15% of polymeric wax, 2-10% of a thixotropic agent and 0.01-0.1% of carbon black. The environment-friendly solvent is adopted in the soundproof wax, so that little odor is generated, a solidified wax layer does not easily drop or is not easily embrittled, and the soundproof wax is favorable in soundproof effect and can be sprayed on a chassis of the automobile.
Description
Technical field
The present invention relates to sound-proof material, particularly relate to a kind of automobile sound insulation wax, be applicable to the sound insulation of automobile chassis.
Background technology
When automobile fast running is on road, the friction on wheel and road surface, also has road surface stone that the shock sound of vehicle chassis very greatly, can be affected to the comfortableness of passenger on car, therefore need to carry out sound insulation and noise reduction process to vehicle.
Chassis armor glue is mostly used to process automobile chassis in the market, to reach anticorrosion, the object of sound insulation, but there is following shortcoming in pitch class chassis armor glue: containing a large amount of noxious solvent, the smell is awful, temperature Gao Shiyi drippage, easily embrittlement come off.
Summary of the invention
For the deficiency that prior art exists, the invention provides a kind of automobile sound insulation wax.
The technical scheme that the present invention takes is: a kind of automobile sound insulation wax, it is characterized in that, be made up of following compositions in weight percentage: petroleum pitch 15%-40%, solvent 25%-45%, filler 15%-40%, micro mist wax 2%-15%, thixotropic agent 2%-10%, carbon black 0.01%-0.1%.
Petroleum pitch of the present invention is one or both mixing in No. 10 petroleum pitch and No. 70 petroleum pitch.
Solvent of the present invention is one or both mixing in No. 200 solvent oils and kerosene.
Filler of the present invention is one or more mixing in talcum powder, process white, mica powder, nano-calcium carbonate.
Micro mist wax of the present invention is one or more mixing in Microcrystalline Wax micro mist, polyethylene wax micro mist, polytetrafluoroethylmodified modified polyethylene wax micro mist, tetrafluoroethylene wax micro mist.
Thixotropic agent of the present invention is one or both mixing in aerosil, organobentonite.
Carbon black of the present invention is oil-soluble pigment carbon black.
The preparation method of a kind of automobile sound insulation wax of the present invention is as follows: be first broken into Powdered by 10# pitch, by 70# asphalt heating to 80-90 DEG C; In reactor, add solvent, stirring at low speed limit, limit adds pitch, regulates moderate-speed mixer to dissolve completely to pitch; After pitch dissolves completely, then stirring at low speed limit, limit adds filler, micro mist wax, thixotropic agent and carbon black successively; After all adding, high speed dispersion 20 minutes; Finally be ground to fineness and be less than 50 microns.
The pitch that the present invention selects is mainly filmogen, strengthens sticking power.Filler mainly plays sound insulation, sound-absorbing.The Main Function of thixotropic agent makes sound insulation wax have thixotropy, is conducive to construction in spraying process, and after spraying, wet film does not trickle.
Feature of the present invention and beneficial effect are: this sound insulation wax uses environmentally friendly solvent, smell little, and the wax layer after solidification not easily drips or embrittlement; Soundproof effect is excellent, and under frequency 400Hz condition, measure oise insulation factor is 15dB-35dB; This sound insulation wax can be sprayed at automobile chassis.
Embodiment
Below in conjunction with embodiment, the present invention will be further described:
Embodiment 1:
Embodiment 2:
Embodiment 3:
Automobile sound insulation wax prepared by above embodiment, the technical indicator is after testing as follows:
