Description
Technical field
The invention belongs to building material technical field, specifically relate to a kind of modified waste tire rubber powder thermal insulation mortar and preparation method thereof.
Background technology
Along with the develop rapidly of automotive industry, produce a large amount of waste and used rubber tyres, " black pollution " that caused thus caused global concern.These tires greatly heap are abandoned together, not only severe contamination the environment of our life, and be the waste of a kind of serious physical resources and land resources, go back utmost point fire hazardous, its incomplete combustion can be emitted hydrocarbon polymer and toxic gas, and its flame is also difficult to put out.Therefore, the processing of junked tire is own through becoming serious social concern.
For the recycling of waste and used rubber tyre, conventional method has both at home and abroad: (1) damaged tire is broken into rubber powder or fiber uses in sand-cement slurry and concrete; (2) as fuel and manufacture the energy; (3) reclaimed rubber is produced in desulfurization; (4) some special purposes, such as manufacturing carbon black, artificial reef etc.These recovery methods still can not utilize all junked tires of China fully, in view of junked tire is by the present situation being doubled and redoubled, should actively improve existing various recovery method, and open up the recovery method making new advances, as far as possible fully recycle junked tire.
At present, in order to meet the requirement of Building Energy Saving, need to do thermal insulation separation thermosphere at existing building construction outer wall body material surface or internal surface, these wall heat insulation materials still exist that heat insulating effect is bad, weight is large, resistance to cleavage, toughness, anti-freezing property, anti-permeability performance and the problem such as anti-vibration noise reducing performance is bad.
Summary of the invention
The invention provides a kind of modified waste tire rubber powder thermal insulation mortar, not only lightweight, and there is splendid temperature stability and chemical stability.Can overcome metope hollowing that traditional mortar in use produces, ftracture, peel off and the problem such as insulation, can also realize the comprehensive utilization of waste old, there is good economic benefit and environmental benefit.
A kind of modified waste tire rubber powder thermal insulation mortar, described thermal insulation mortar comprises the component of following weight parts: 100 parts of cement, 50 parts, water, 56～168 parts of sands, 112～224 parts of using rubber powder of waste tire, 1.12～4.48 parts of silane coupling agents.
As preferably, described using rubber powder of waste tire is fineness through the surperficial mechanical force modification using rubber powder of waste tire between 40 order～80 orders.
As preferably, described using rubber powder of waste tire surface mechanical force modification processing method is mechanical ball milling processing, and Ball-milling Time is no more than 0.5 hour.
It is due to the result of grinding element to its impact and grinding that material is pulverized in mechanical milling process.But its crushing process is but very complicated.If taking a certain independent particle as research object, in mechanical milling process, it may be subject to grinding the effect of stress repeatedly, causes and is present in crack propagation intrinsic or newly-generated on this particle surface, and then be directed at that it is broken or produce viscous deformation.In the time that this particle is constantly pulverized. the new particle of certain one-level of generation is just difficult to further levigate, and this is because the lip-deep crackle of new grain is thinner, and the cause that also reduced of the crackle probability that occurs a certain minimum rupture stress.In the time that shattering process is proceeded, required finished breaking stress may increase to and make particle produce the degree of viscous deformation.Now, along with the generation of viscous deformation, particle just can be by not levigate.Therefore, have a granularity ultimate value when grinding material.This limit depends on that grinding product particle produces the tendency of again building up mainly, and the physical equilibrium of setting up between accumulation and fragmentation.Therefore, long prolongation Ball-milling Time is skimble-skamble, only can cause the increase of energy consumption, because meticulous particle cannot store the elastic energy that makes crack propagation required effectively.
As preferably, described silane coupling agent is silane coupling agent KH560.Improve the cohesive force of using rubber powder of waste tire and sand-cement slurry.
As preferably, described silane coupling agent KH560 presses 1.5%～2% of using rubber powder of waste tire quality and adds.
As preferably, described thermal insulation mortar comprises the component of following weight parts: cement 100 weight parts, water 50 weight parts, sand 90 weight parts, fineness are 65 object using rubber powder of waste tire 200 weight parts, silane coupling agent KH560 4.0 weight parts.
A preparation method for modified waste tire rubber powder thermal insulation mortar, comprises the steps:
