Abstract
The invention relates to a damping vibration reduction material and a damping vibration reduction board used in a noise treatment part of a large noise device. The material components and weight portions of the damping vibration reduction material are as follows: 70 to 90 portions of asphaltum; 3 to 10 portions of salamander wool; 5 to 15 portions of talcum powder; 1 to 3 portions of castor oil; and 2 to 4 portions of boiled wood oil. The material has the excellent technical performances of high damping factor, broad damping temperature domain, innocuity, high sticking force, vibration and noise reduction, flame resistance and heat isolation, good seal effect and the like. The vibration reduction performance of the material can achieve 13 decibels which is higher than the performance of the products of the same category by 15 to 35 percent, the pressing resistance intensity is improved by 1.5 times, and the invention has normal temperature reaction solidification, is convenient to be constructed and can be used for various complex curves; moreover, the construction thickness can be adjusted.
Description
Technical field
The present invention relates to a kind of in the noise abatement parts of big noise equipment this damping material of employed resistance and damping vibration attenuation plate.
Background technology
The metal constructions such as housing of hood, airduct and the machinery equipment made from metal sheet, regular meeting gives off stronger noise because the conduction of vibration makes these sheet metal shell that vibration tempestuously take place.The effect of damping vibration attenuation material is vibrational energy to be converted into thermal dissipation fall, and makes the big lossy of vibrational energy that produces noise, promptly controls vibration and noise effectively from sound (shaking) source.Therefore damping vibration attenuation material is mainly used in vibration and generating noise position, and its main products of damping vibration attenuation material has in the market: damping cream, damping sheet material, damping paint, selfadhesive damping sheet material, flame-retardant hot-melt type damping sheet material, flame retardant type magneticdamping sheet material, basic unit's dressing etc.
Overall targets such as the damping property of existing damping vibration attenuation material, withstand voltage properties, damping factor and damping temperature domain are difficult to satisfy the vibration damping requirement of some big noise equipment; Existing damping vibration attenuation material is generally by linking to each other damping vibration attenuation material by self-adhesive with object, promptly apply the very thin pressure-sensitive non-setting adhesive of one deck at body surface, though can paste temporarily, but environment and temperature all can produce a very large impact work-ing life, not water-fastly do not prevent fires yet, wire drawing and obscission should occur, in general 1～3 year of work-ing life, severe cold or high temperature area life-span are shorter.
Summary of the invention
Technical problem to be solved by this invention is, provide a kind of damping factor height, damping temp field width, nontoxic, bonding force is strong, damping property good, the damping vibration attenuation material and the damping vibration attenuation plate of anti-flaming thermal-insulation, sealing effectiveness, easy construction on equipment.
The raw material composition and the weight part of damping vibration attenuation material of the present invention are: pitch 70-90 part; Asbestos wool 3-10 part; Talcum powder 5-15 part; Viscotrol C 1-3 part; Boiled wood oil 2-4 part.
The manufacture method of damping vibration attenuation plate of the present invention is the raw material of above-mentioned damping vibration attenuation material to be merged down at 250-400 ℃ according to ratio of components make macromolecule polymer material, and 170-185 ℃ down with insulating board bonding formation damping vibration attenuation sheet material.
Damping vibration attenuation material of the present invention itself has the characteristic of fire protection flame retarding, water-tight corrosion-proof, it is convenient to construction, ability is temperature more than 110 ℃, existing stronger sticking power, good snappiness is arranged again, can play the effect of damping vibration attenuation, sound insulating and absorbing effectively, in the normal temperature environment for use, can use more than 15 years.Through actual detected, material of the present invention has damping factor height, damping temp field width, nontoxic, good technical features such as bonding force strong, vibration and noise reducing, anti-flaming thermal-insulation, good sealing effect, its damping property can reach 13 decibels, be higher than like product performance 15-35%, compressive strength improves 1.5 times, and normal-temperature reaction is solidified, easy construction, the curved surface that can be used for various complexity, construction thickness is adjustable.
Embodiment
Embodiments of the invention are as follows:
With pitch, asbestos wool, talcum powder, Viscotrol C, boiled wood oil weight ratio according to 80:4:11:2:3, merge down at 320 ℃ and to make macromolecule polymer material, and in the time of 180 ℃ with the insulating board bonding, lean on self permanent stickiness and insulating board to fit tightly.
The actual performance index of the damping vibration attenuation material of the embodiment of the invention is as follows:
1. heat resistance is better, and yield does not appear in subzero 40 ℃ of degree bendings to be split, and trickling and obscission do not appear in 110 ℃ of degree above freezing;
2. material self damping factor 0.6----1.95
3. flame retardant resistance (V/V%) 〉=32
4. density≤1600kg/m
