Description
Technical field
The present invention relates to field of adhesive technology, more particularly to sound insulation is built in a kind of high one-component epoxy resin capital construction of toughness
Glue and preparation method thereof.
Background technology
With the fast development of China's building trade, New Building Materials are also continually developed and are applied, in order to meet stone material,
The bonding of most of construction materials such as timber, concrete, metal, pottery and glass is required, gluing based on epoxy resin
Agent is widely used in building field, and the application development especially as structure glue is very rapid, and its range of application is from home
Finishing, the reparation of building and reinforce and extend to the construction of new building, and from common buildings develop into highway, bridge, high ferro,
The numerous areas such as water conservancy, airport, become the new important chemical building material of a class.
With the development of China's architectural engineering, existing commercialization epoxy resin architecture adhesion agent can not still be fully achieved newly
Technical requirements, the adhesive for developing all kinds of technical requirements of new architectural engineering become the active demand in market.Building work
Journey epoxyn is mainly used in " integrated engineering " of concrete, the repairing of bonding building, the repairing of cement products, dress
Repairing of bonding and architectural pottery of decorations and finishing material etc..But after traditional epoxy resin cure, toughness is poor, therefore exists
While keeping higher-strength, toughening modifying is carried out to epoxy resin imperative.Again as epoxy resin belongs to combustible material,
Its oxygen index (OI) only has 19.5 or so, applies so as to limit which.The characteristics of based on above epoxy resin, it is necessary to which which is modified
Fire-retardant toughened adhesive is made in process, it is ensured that human life and composition of estate is not threatened during use, to reach architectural engineering
Need.
《The development of fire-retardant building structure adhesive》Based on polyurethane (PU) Toughening Modification of Epoxy, with inflatable
Graphite (EG)/APP (APP) is synergistic flame retardant, is prepared for a kind of fire-retardant building structure adhesive.As a result show, through changing
Property after this epoxyn impact strength improve 63.4%, reach good toughening effect, shear strength reaches 24.9MPa,
Oxygen index (OI) can be used as fire-retardant building structure adhesive up to 28%.
But with expansible graphite as fire proofing in text, high cost is unfavorable for producing in batches, and with application
Expand, the requirement more and more higher to architecture adhesion agent, in addition to mechanical property, adhesive property, fire resistance etc. are required, the side of being
Just construct, user more welcomes monocomponent adhesive, it is not necessary to the operation such as scene weighs, configuration, mixing, work efficiency can be improved；In addition,
With raising of the people to quality of life, in addition to requiring that the long weatherability of building equivalent life is good, people are required to living environment
Also more and more higher especially build sound insulation and noise reduction demand stricter so that in addition modified to existing building adhesive,
On the basis of its combination property is ensured, add the sound insulation property that corresponding additive improves adhesive, therefore utilize industrial production
The waste residue of generation is in addition modified, and optimization of C/C composites improves existing production technology, develops a kind of one pack system ring with sound insulation function
Epoxy resin-based building acoustic mastic is necessary.
Content of the invention
The object of the invention is exactly the defect in order to make up prior art, there is provided a kind of high one-component epoxy resin base of toughness
Building acoustic mastic and preparation method thereof.
The present invention is achieved by the following technical solutions：
Acoustic mastic is built in a kind of high one-component epoxy resin capital construction of toughness, is prepared by the raw materials in：E-44 asphalt mixtures modified by epoxy resin
Fat 58-61, polyurethane 19-21, carbide slag 13-15, aluminium powder 0.02-0.03, nano barium sulfate 0.8-0.9, potassium sulfate 0.2-
0.4th, dimethicone 1.2-1.5, ball-shaped silicon micro powder 4-6, carbon fiber 2-3, polyetheramine 6-7, maltodextrin 9-10, vinyl three
Methoxy silane 2.5-2.8, mixed solvent 80-83, suitable quantity of water, the mixed solvent are according to mass ratio 8 by ethanol, n-butanol
: 2 are compounded.
The preparation method that acoustic mastic is built in a kind of high one-component epoxy resin capital construction of described toughness, comprises the following steps：
（1）90 DEG C of -98 DEG C of boiling water are added toward maltodextrin, pre-gelatinized is stirred well to, room temperature is cooled to and is added vinyl three
Methoxy silane, nano barium sulfate ultrasonic disperse grinding 10-15 minutes obtain modified maltodextrin；
（2）By carbide slag in 825-865 DEG C of high-temperature calcination 20-30 minute, it is cooled to room temperature and is crushed to 180-200 mesh, add step
Suddenly（1）Material stirring is mixed, and is added aluminium powder, ball-shaped silicon micro powder, carbon fiber and suitable quantity of water to stir into and starch and granulate, is then placed in quiet
In 55-65 DEG C of sealing thermal insulation, 2-2.5 hours of resting are dried for foster room；
（3）E-44 epoxy resin, polyurethane are put in reactor, is added mixed solvent to stir and evenly mix, is heated to 80-90
DEG C, instill dimethicone keeping temperature stirring reaction 2-3 hour；
（4）By step（3）Material is cooled to 45-55 DEG C, adds step（2）Reaction mass, polyetheramine and other residual components, permanent
Temperature stirring 1-2 hours, stop heating, are cooled to room temperature under agitation, discharge.
It is an advantage of the invention that：The present invention based on polyurethane-modified epoxy resin, both can in system shape
Into certain network structure, it is to avoid larger internal stress in system, fragility reduced, improve the anti-cracking ability of system,
The effect of activeness and quietness is reached；Carbide slag is carried out there is after physical and chemical modified process pore structure and porosity is uniform,
Product sound-adsorbing sound-insulating hung performance is not only improved, also so that product is when high temperature is subject to moment, due to the chemical combination being occluded in hole
Thing decomposes, and pore expands rapidly, and when fire occurs by the expansion of volume moment by fray-out of flame, flame retardant effect is excellent and environmental protection
Pollution-free；Last other effective auxiliary agents of compatibility again are mutually combined high obtained building acoustic mastic toughness, shock resistance and shear strength
Height, for multiple material all has good caking property and permeability, adhesion strength is high, and bonding gap is closely knit firm.
