Description
Technical field
The present invention relates to a kind of sound insulation and noise reducing engineering materials, be specifically related to a kind of particulate soundproofing lagging and preparation method thereof.
Background technology
Modern society's sound pollution has become a subject matter of environmental pollution, and soundproofing lagging is the comparatively normal product used in noise control engineering just.Soundproofing lagging, as the term suggests, refer to a kind of can by propagate in air the isolation of noise, partition, separation sheet material.Generally speaking, the material with certain mass all has certain sound insulation property, and soundproofing lagging will weaken transmission acoustic energy, the propagation of block sound, and its material should weigh and closely knit, requires its closely knit imporosity or gap, and has larger weight.Noise reduction engineering generally adopts metallic substance (as iron and steel, aluminium etc.) and non-metallic material (as cement soundproofing lagging etc.) do soundproof material, but in use there is many problems in it.Metal sound insulation material not only price, because its rigidity is also relatively weak, its sound insulation property is not ideal enough, and its antiseptic property can not meet service requirements.
Cement fibre soundproofing lagging is with a kind of sheet material of the inorganic hydraulic gelling material such as wood fibre mixed cement, sand through extrusion forming, because wherein containing wood fibre, water resistance is poor, dry indoor environment can only be used for, run into its sound insulation property moist will greatly reduce, its visual appearance is not good enough simultaneously, generally directly can not use as exterior wall.And cementitious materials can form micropore when evaporation coagulation is shaping, the existence of micropore not only reduces the water-repellancy of Cement fibre soundproofing lagging, also have impact on its sound insulation property.
Summary of the invention
Object of the present invention is just for above-mentioned the deficiencies in the prior art, a kind of novel soundproof material is provided, it take particulate as raw material, not only there is good sound insulation property, but also there is good anticorrosion and water resistance, can directly use as exterior wall, it possesses the color (such as colored sand grains) of particulate itself simultaneously, and the combination by different colours particulate meets the requirement of client to aesthetic appearance.
The invention provides a kind of novel particulate soundproofing lagging, it is using particulate as soundproofing lagging base material, and its structure comprises skeleton and stopping composition, and stopping composition fills up skeleton gap; Described skeleton is formed by skeleton particulate is bonding, and described stopping composition comprises fills particulate, binding agent and coupling agent.
The particle diameter of above-mentioned skeleton particulate is 2-8 times that fills diameter of particle.
Further, described skeleton particulate comprises large skeleton particulate and little skeleton particulate, and large skeleton diameter of particle is 2 times of little skeleton diameter of particle.
Preferably, the median size of described large skeleton particulate is 0.8mm, and the median size of little skeleton particulate is 0.4mm.
Further, described skeleton comprises the little skeleton that the large skeleton that formed by large skeleton particulate and little skeleton particulate are formed.Preferably, between adjacent two-layer large skeleton, two-layer little skeleton is set.
The preferred version of skeleton particulate and filling diameter of particle is: the median size of described skeleton particulate comprises 0.8mm and 0.4mm, and the median size of filling particulate comprises 0.2mm and 0.1mm.
Further, the weight part of described skeleton particulate and filling particulate consists of: φ 0.8mm particulate 40-45 part, φ 0.4mm particulate 40-45 part, φ 0.2mm particulate 3.5-7 part, φ 0.1mm particulate 7-14 part.
In order to ensure that soundproofing lagging is closely knit seamless, the dihedral coefficient of sound insulation particulate is selected to be greater than 1.5.
Preferably, above-mentioned sound insulation particulate is selected from the particulate that sand grains, haydite and regenerated building waste material are formed, and these raw material light weights are inexpensive, wide material sources, thus the production cost reducing soundproofing lagging of the present invention.
Simultaneously in order to ensure cohesive strength and the cohesive force of particulate, described binding agent is selected from epoxy resin, resol, urea-formaldehyde resin and furfuryl alcohol resin, and the add-on of binding agent counts 4-6% with the particulate weight that insulates against sound, ensure that all bonded dose of the gap that in soundproofing lagging, particulate is formed also prevents binding agent from overflowing and causes waste while of filling up.
Add silane coupling agent and the coupling agent containing isobutyl functionality in a binder, add-on counts 1-5% with weight of binder, adding of coupling agent can form water-repellent layer on soundproofing lagging, suppresses moisture to enter into particle board inside, thus makes soundproofing lagging have waterproof, antiseptic property.
Soundproofing lagging prepared by the employing particulate of novelty of the present invention, has good weathering resistance and visual appearance.The soundproof material that existing exterior wall uses, such as color steel, by strict rotproofing, must could meet the preliminary use of engineering.Because expose steel in an atmosphere, to be easy to corrode by acid rain.But particulate soundproofing lagging of the present invention adopts hard particulate (as quartzy sand grains, haydite etc.) to be raw material, and its main mineral constituent is SiO
2have the advantages such as hard, wear-resisting, stable chemical performance, the present invention simultaneously makes caking agent with epoxy resin, resol, urea-formaldehyde resin and furfuryl alcohol resin, thus the particulate soundproofing lagging that the present invention is obtained has good weathering resistance, not easily be corroded, can directly use as exterior wall.Soundproofing lagging of the present invention possesses the color of particulate itself simultaneously, and the combination by different colours sand grains meets the various demands of client to outward appearance.Therefore soundproofing lagging advantage of lower cost of the present invention, sound insulation property is good, directly can use as exterior wall, have good market outlook.
As everyone knows, space must be formed in the middle of particulate and asperity contact, and the requirement of soundproofing lagging is closely knit seamless, therefore in order to ensure that the space between particulate is all closed, thus reach the requirement of soundproofing lagging, completely intercept sound wave penetrate, the present invention determines following technical proposals: by add different-grain diameter fill up compared with small particle and excessive binding agent the space formed between Large stone particulate.
And the selection of diameter of particle and composition are worthy of careful study, through the repetition test of contriver, finally determine that particulate composition is optimum with following: φ 0.8mm particulate 40-45 part, φ 0.4mm particulate 40-45 part, φ 0.2mm particulate 3.5-7 part, φ 0.1mm particulate 7-14 part.
This is because, in theory, as long as filled up completely in the gap of particulate, just can good sound insulation property be obtained.But consider from the angle of Practical, first this soundproofing lagging must have enough physical strengths, it should be lower for becoming simultaneously.
According to the particulate of small particle size as skeleton, fill less particulate, also good defening effect can be obtained, but because the soundproofing lagging of small particle composition is under the prerequisite of same volume, the total surface area of particulate is greater than the total surface area of large particulate formation, therefore the consumption of binding agent is large, and economy is bad.Meanwhile, we know, the bond area between particulate is and square being directly proportional of particle radius, therefore the physical strength of large particulate is better than small particle.
Adopting particulate to be that soundproofing lagging prepared by raw material is closely knit seamless to ensure further simultaneously, the present invention proposes a kind of layering method of forming.This is because according to the mode that the particulate of different-grain diameter is directly mixed, its uniformity coefficient not easily ensures, the present invention adopts the skeleton of particulate as soundproofing lagging of 0.8mm and 0.4mm two kinds of particle diameters, when shaping, first lay one deck 0.8mm particle, at the two-layer 0.4mm particle of laying, the gap can staggered very well each other like this, thus ensure that the small particle size of 0.2mm and 0.1mm is filled particulate and put into the space that can enter smoothly and fill between skeleton, be beneficial to gap to be completely filled, thus improve the sound insulation property of soundproofing lagging.Its preparation method comprises the following steps:
(1) particulate of the binding agent and different-grain diameter that add coupling agent is in advance uniformly mixed respectively, places 0.2-0.5 hour; Particulate consists of φ 0.8mm particulate 40-45 part, φ 0.4mm particulate 40-45 part, φ 0.2mm particulate 3.5-7 part, φ 0.1mm particulate 7-14 part; The add-on of binding agent counts 4-6% with particulate weight, and the add-on of coupling agent counts 1-5% with weight of binder;
(2) in mould, lay one deck φ 0.8mm particulate vibratory compaction;
(3) in the mould of step (2), two-layer φ 0.4mm particulate vibratory compaction is laid;
(4) in the mould of step (3), constantly vibration adds φ 0.2mm particulate and φ 0.1mm particulate until stop adding of particulate when particulate no longer falls in mould;
(5) compressed by the particulate in step (4) mould, the demoulding is dried and be get final product.
Simultaneously can according to the thickness of required soundproofing lagging, constantly repeat (2) to (4) step until compress the demoulding after reaching desired thickness and dry.As shown in Figure 2, the thickness of soundproofing lagging is thicker, and sound insulation property is better.
The present invention is by the preparation method of layering, substep jolt ramming, staggered in the gap of particulate, and the particulate of small particle size is added by gradation, make to enter in the space formed between Large stone particulate compared with the particulate of small particle size to play filling effect, thus ensure that particulate soundproofing lagging is closely knit seamless.
