Description
Technical field
The invention belongs to building material technical field, be specifically related to waste or used plastics, sepiolite fibre composite asphalt modifier and preparation method thereof.
Background technology
It is master's New Times that Chinese at present highway cause has got into to build high-grade highways such as motorway, Class I highway, and the flourish pavement quality to motorway of motorway is had higher requirement.The problem of motorway ubiquity weathering resistance difference is mainly reflected in the bituminous high request at present.Traditional pitch exists wax content high when directly using, temperature sensitivity is big, and shortcomings such as thermostability and crack resistance at low-temperature difference are easy to crack, stability to aging is poor.In order to improve the bituminous pavement quality; Often to carry out modification to pitch as required; At present methods of the various interpolation properties-correcting agent of interpolation in pitch that adopt are carried out modification to pitch more; Improve bituminous thermostability, cohesive force, cracking resistance seam ability and weather resistance etc., in the hope of satisfying high-grade highway to the bituminous request for utilization.
Chinese patent 200610017564.1 discloses a kind of pitch filler compsn that improves asphalt performance, and it is in pitch, to add sepiolite, wollastonite, talcum and bar compsn, mainly improves bituminous cementability and anti-cold(ing)crack property.Chinese patent 201010155339.0 discloses a kind of asphalt combined fiber filler of being made up of pitch, sepiolite fibre, brucite fiber, has advantages such as the bituminous of raising cementability, anti-cold(ing)crack property and minimizing pavement track displacement disease.Adopt mineral grain or mineral fibre filled bitumen; Bituminous cementability and anti-cold(ing)crack property have been improved to a certain extent; But segregation and deposition take place in bituminous processing, transportation and storage process easily, cause the inhomogeneous even destruction bituminous physicals of modification.
Reclaiming and utilizing waste plastics comes into one's own as the measure of a save energy, protection environment just day by day in the rubbish, and especially developed country's work starting has early been received tangible benefit.Rubbish is screened, reclaim useful plastics, both can effectively reduce the rubbish total amount, significantly reduce the composition of difficult degradation in the rubbish, again for plastic molding and processing plant has solved the insufficient problem of waste or used plastics supply and demand, for producer provides cost savings.Waste or used plastics can be widely used in Wood-plastic material, material of construction, coating and tackiness agent etc. through modification regeneration.Patent CN101225237B discloses a kind of with modifying waste plastic bituminous method, can improve bituminous softening temperature and road surface high-temperature stability.Modifying waste plastic pitch there is more deep research both at home and abroad; But most waste or used plastics is difficult to form stable system during blend in pitch; Can not standing storage, stability is bad, on the problem that solves the pitch stability to aging, still has bigger difficulty.
Summary of the invention
The object of the present invention is to provide a kind of waste or used plastics to be applied to the technical scheme of modified asphalt material, through effective proportioning of raw material of the present invention, the material modified bituminous cementability and the anti-cold(ing)crack property improved preferably of gained.And the present invention can make full use of the waste or used plastics resource, turns waste into wealth; Provide a kind of waste and old resources effective to utilize approach.
A kind of waste or used plastics/sepiolite fibre composite asphalt modifier that the present invention proposes is made by raw material sepiolite fibre, trimeric cyanamide, polyolefine, coupling agent and expanding material.
Composition of raw materials is following:
The granularity of said sepiolite fibre is 0.2-5mm, and porosity is the sepiolite fibre of 32-48%.
