Description
Technical field
The present invention relates to PET reclaiming and utilizing waste plastics method, be made into the plastics mortar, can be used for repairing damaged concrete road surface fast, also relate to the preparation method of this mortar, belong to the recycling and the building material technical field of plastics.
Background technology
Along with the continuous increase of beverage quantity and kind, the usage quantity of PET bottle constantly increases, and is applied to pure water at present, mineral water, tea drink, beer, and the packing of beverage such as milk.At present the whole world uses pet container quantity to reach 1,500 hundred million, and only in range of Beijing, the waste PET bottle total amount of 2009 contracts has reached 150,000 tons, is about 6,000,000,000 waste PET bottles in China, and is existing still with annual 20% speed increase.Owing to there is not an effective biodegradation method, the rapid growth that the PET Plastic Bottle uses and the environmental problem brought highlights is day by day deposited so many Plastic Bottle and also can be occupied a large amount of land resources.Unsuitable processing also can pollute environment like burning, so the regenerated using of waste PET carafe is for economizing the land resource, and material resources and protection environment are significant.The concrete road surface in use owing to factor affecting such as load, environment, design, constructions, the road surface local damage can occur.If these local diseases among a small circle can not get repairing effectively and timely, will cause damaged scope further to enlarge, disease is further aggravated, and finally causes even more serious destruction.When repairing, the gain in strength speed of material is restricting the time of open to traffic.Early strong, competent fast repairing material can shorten the road closed time, significantly reduces the influence to traffic, has good social effect and economic implications.
Domestic also have a lot of materials about road quick patching open, and for example, patent 201010186653.5 discloses a kind of road quick patching material, is by 1 part of special cement; 0.14～0.13 part of Portland cement; 0.05～0.08 part of high molecular polymer; 0～0.01 part of construction auxiliary agent; 0～0.05 part of swelling agent; 0.05 part of adulterant; 1.18～1.12 parts in sand is formulated, has quick repairing road surface and open to traffic at short notice, advantage.Patent 200510061384.9 discloses a kind of filling material for repairing road surface at quick speed, by 70～80 parts of pitches, and 60～80 parts in tar, 450～500 parts of silicon-dioxide, 350～450 parts in sandstone material.The stone weight content is 40～60% in the described sandstone material, and the sand weight content is 40～60% to form, have simple to operate fast, repair the advantage that the back can be open to traffic in 2～3 minutes.Patent 201010183541.4 discloses a kind of super early strength polymer rapid-patching motar material; Form by rapid hardening cement 36%～50%, silica sand 42%～54%, polymeric viscosifiers 2%～10%, thickening material 0.1%～0.5%, hardening accelerator 0.1%～0.8%, adjustable solidification agent 0.15～0.9%, water reducer 0.1%～0.6%, skimmer 0.02%～0.1%, staple fibre 0.01%～0.08%, have soon advantages such as rapid hardening firmly and not, waterproof impervious characteristic is good, the cracking resistance ability is strong and easy to use.Though these materials all can be realized the quick repairing of road, its moity is many, and prescription is complicated, and does not all have to disclose with waste or used plastics as moity.
People such as the Niji Khoury of Oklahoma university mention PET and soil or sand heating and melting under 275 ℃ condition at " Soil Fused with Recycled Plastic Bottles for Various Geo-Engineering Application "; Form the plasticine material of homogeneous, the PET consumption that is adopted is PET: sand=1:1.At optimum PET consumption; The grating of sand and pitch interpolation aspect, Khoury does not conduct a research, and the made plasticine of Khoury mainly is used as the sticker that open gradation gathers materials; Be used for making water-permeable pavement, the plastics mortar be not used for the quick repairing of road.
Summary of the invention
The present invention provides a kind of recoverying and utilizing method of PET plastics according to the problem of existing plastic material recovery and the big difficult treatment of usage quantity, and this method has been practiced thrift resource, protected environment, has good social effect and economic implications.
It is strong plastics mortar morning of one of raw material that the present invention also provides with the PET plastics, and this mortar strength increases fast, useful as concrete repairing road surface at quick speed mortar, and 3h ~ 6h can be open to traffic, and can satisfy the requirement of Rapid Road Patching Material.
The present invention also provides the preparation method of this morning of strong plastics mortar, and present method technology is simple, and easy handling is implemented.
According to the content of prior art, the contriver has carried out further research to the waste PET plastics in the application in the morning strength mortar, and research shows, if control the add-on of PET plastics well, this recovery method is feasible.According to the described test technology of Khoury, the contriver has carried out further research, and the result adopts the sand of optimizing grating, and uses domestic PET plastics, and plastics mortar ultimate compression strength made under the condition of PET: sand=1:1 is 19.6MPa.And the addition content of change PET, the resistance to compression of gained mortar, folding strength have all had significant raising, and embodiment is following:
