Description
Technical field
The invention discloses a kind of noise reducing type glass fiber compound materials, belong to building material technical field.
Background technique
In a broad sense, noise, which refers to, allows the uncomfortable sound of the mankind, belongs to a major class of environmental pollution, with air
Pollution, water pollution together, are listed in the three overall situation pollution sources in the present age.With modern industry, construction industry and transportation
Deng development, the problem of noise pollution also becomes increasingly conspicuous, it has also become influences people's quality of life and is detrimental to health main
One of factor.Therefore, the noise pollution for how reducing environment, arouses widespread concern.
Make a general survey of the work done in terms of reducing pollution from environmental noise, it can be seen that mainly at two aspects: being on the one hand
Noise source is controlled and is administered, i.e., the big scrap build of noise is become into the small or even mute equipment of noise；Second is that making an uproar
Noise reduction is carried out in the Acoustic Wave Propagation approach of sound, mainly develops various partitions or the sound insulation of absorption noise or sound-absorbing material.
In order to effectively separate noise, traditional acoustic material is mostly thick and heavy type, the range limited its application.With room rate rising and
Increase of the people to space requirement, the requirement to thin light Acoustic barrier plate are higher and higher.Xin Feng is first equal theoretically to be had studied
The sound insulation property of light-weight metal sandwich boards shows that the plate of sandwich structure has good sound insulation value.Yu Laiming etc. is ground
Influence of the spread pattern of reinforcing material to composite material sound insulation value is studied carefully.Yang Tianbing etc. has studied honeycomb weave fabric enhancing polychlorostyrene
The sound insulation value of ethylene composite material.There is a company, has developed a kind of novel soundproof construction composition, this soundproof construction
Material is and the fire-retardant soundproof plate enhanced with glass fibre foaming body using the old glass of recycling as foaming body.Though
These right acoustic materials have good sound insulation value, but are difficult to meet the multiple requirements that people separate premises.It passes at present
System noise reducing type glass fiber compound material the problem of can not being promoted simultaneously there is also sound insulation value and mechanical property, therefore also need pair
It is studied.
Summary of the invention
The present invention solves the technical problem of: for traditional noise reducing type glass fiber compound material sound insulation value and power
The problem of performance can not be promoted simultaneously is learned, a kind of noise reducing type glass fiber compound material is provided.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:

Glass fiber powder, according to parts by weight, by 20~30 parts of single treatment glass fiber powders, 2~3 parts of biogas slurries, 1~2 portion of sucrose, 30
~40 parts of sodium alginate solution mixed fermentations are subsequently added into the ferric chloride solution of 0.1~0.2 times of single treatment glass fiber powder quality
It with 0.1~0.2 times of Fluorinse of single treatment glass fiber powder quality, is stirred, filters, wash, charing rises step by step
Temperature, pyroreaction cool down to get modified glass-fiber powder.
The low-melting alloy powder is bismuth tin alloy powder, and wherein bismuth accounts for 50%(ω), tin accounts for 31%(ω), lead accounts for 10%(ω),
Indium accounts for 9%(ω).
The preparation process of the modified micro-capsule are as follows: by linseed oil and gelatin solution be in mass ratio 1:10~1:15 mix point
It dissipates, obtains lotion, add the metabisulfite solution of quality of the emulsion 8~10%, after heating stirring mixing, cooling, and quality of the emulsion is added dropwise
5~7% formalin, then pH to 9.6~9.8 is adjusted, it is then cured, it filters, washing and drying are to get modified micro-capsule.
The phosphatide is soybean lecithin, any one in yolk phospholipid or milk phosphatide.
The beneficial effects of the present invention are:
The present invention is by addition modified glass-fiber powder, calcium bicarbonate and low-melting alloy, during the preparation process, firstly, glass
Fiber powder is impregnated by sodium hydroxide solution, using sodium hydroxide etching glass fiber, so that the roughness of fiberglass surfacing
It is promoted, then by fermentation, bacterium is enabled to adhere to and breed in fiberglass surfacing, then pass through addition iron chloride
Solution, bacterial cell wall surface is negatively charged, and the iron ion in system can be adsorbed by bacteria cell wall, so that a large amount of iron ion
It is enriched in bacterium surface, then, in carbonization process, the organic matter of fiberglass surfacing is carbonized, meanwhile, iron ion is reduced into
Fe, and fiberglass surfacing is fixed on by carbonaceous layer, in high-temperature reaction process, make in the catalysis of fe and sodium fluoride
Under, the silica of fiberglass surfacing and the charcoal qualitative response on its surface generate silicon carbide, so that the mechanical property of system obtains
To promotion, in use, calcium bicarbonate is thermally decomposed, and generates a large amount of carbon dioxide gas, so that being formed in system big
The through-hole of amount has just melted, alloy simultaneously as low-melting alloy has lower fusing point before branch is fully cured
It can be very good to disperse and surround fe after ion fusing, after alloy graining, may make and form metallurgical bonding between glass fibre,
So that the mechanical property of system gets a promotion, meanwhile, the formation of metallurgical bonding is formed a large amount of so that the through-hole in system separates
Closed pore so that the sound insulation value of system is further promoted.
