Description

A kind of decoration interior sound insulation material
Technical field
The present invention relates to a kind of nonwoven acoustic insulator material, be specifically related to a kind of decoration interior trim expanded vermiculite-urethane composite emulsion coating thermoplastic phenolic resin nonwoven acoustic insulator material.
Background technology
Now, along with the continuous acceleration of urbanization, noise pollution also becomes more and more serious.In order to effectively cut off noise, common settling mode uses sound-proof material.Existing sound-proof material is generally cement concrete, sheet glass etc., these sound insulations etc.The soundproof effect of these sound-proof materials is not very well, and therefore common terms of settlement strengthens the thickness of sound-proof material.The problem caused like this is that sound-proof material quality is overweight, high cost, and installation process is very inconvenient.
The polypropylene-base composite nonwoven material obtained with meltblown is with its ultra-fine fibrous texture, produce simple efficient, the feature such as nontoxic becomes the sound-proof material of class widespread use in automotive trim, the most short texture of these materials, smooth fibrous outer reduces the specific surface area of material, thus sound wave oscillatory extinction transformation time is in the material shortened, do not reach gratifying soundproof effect, noise reduction is promoted often through increase material thickness when reality uses, finished product exists yielding simultaneously, anti-rebound resilience is poor, easy generation electrostatic, the shortcomings such as poor heat resistance.
Summary of the invention
For the deficiency of current material, the object of the present invention is to provide a kind of expanded vermiculite-urethane composite emulsion coating thermoplastic phenolic resin nonwoven acoustic insulator material.This material has larger specific surface area, and in structure, comparatively traditional non-woven materials 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 decoration interior sound insulation material, described sound-proof material is made up of the raw material of following weight part: thermoplastic phenol's resin 42-56, expanded vermiculite 20-25, polystyrene foamed plastics 4-6, silane coupling agent 2-3, nano carbon black 1-1.5, polymethylmethacrylate 8-10, oxidation inhibitor 0.1-0.2, whipping agent 0.1-0.2, magnesite 0.2-0.3, solid content is the silicon dioxide gel 2-3 of 10-15%, 100-200 order polynite 20-24, solid content is the aqueous polyurethane emulsion 10-12 of 8-10%, collegen filament 10-20, waste wool felt 20-30, auxiliary agent 2-5, described expanded vermiculite doubly forms the particulate matter by inside with countless tiny thin layer hole through 1000-1200 DEG C of high-temperature roasting enlarged volume 15-25 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 lauryl sulphate 0.5-0.6, propylene glycol 3-5, solid content are zirconia sol 4-5, nano-nickel oxide 0.6-0.8, the water 10-12 of 15-20%, preparation method is: first drop in water by propylene glycol, sodium lauryl sulphate, 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-nickel oxide, to obtain final product.
Preferably, described defibrination rotating speed is that 4000-6000 turns.
Preferably, the solid content of described zirconia sol is 18%.
Preferably, the solid content of described aqueous polyurethane emulsion is 9%.
Preferably, the consumption of described expanded vermiculite is 23 parts.
Usefulness of the present invention is: a kind of expanded vermiculite prepared by the present invention-urethane composite emulsion coating thermoplastic phenolic resin nonwoven acoustic insulator quality of materials is light, and thickness is little, and soundproof effect is very good, has good market outlook.The advantage of conventional polypropylene nonwoven material has been acted on through the fibre web material that obtains of composite modified master batch spray silk, and its mechanical property improves, possesses excellent weatherable, long-time use is indeformable, and the urethane composite emulsion of preparation is after the coated solidification of fiber surface, the material wherein adulterated makes fibre web intensity improve, and damping is strengthened, and effect of vibration and noise reduction is obvious; Sound-proof material light weight environmental protection prepared by the present invention, noise reduction is lasting, and not polluting environment inside car, is a kind of Soundproof material for vehicle of novel practical.
