Description
Technical field
The present invention relates to a kind of Compositional type SBS modified pitch steady heat storage agent, belong to Fine Organic Chemical product field.
Technical background
Colophonium is the raw material that road traffic, buildings waterproof and industrial antisepsis are conventional.Along with road traffic is to Colophonium serviceability
Requirement improves constantly, and the inherent defect of matrix pitch restricts its development and application, and asphalt modification technology is arisen at the historic moment.Colophonium at present
The kind of modifying agent and method of modifying are a lot, the most especially with the application of SBS modified pitch and with the fastest developing speed, account for whole world Colophonium
The 60% more than of usage amount.
SBS is a kind of non-polar polymeric material, and relative density is less than 0.9, and Colophonium is the mixture that a kind of composition is extremely complex,
Containing polar component, relative density is more than 0.9；Both cause segregation phenomenon occur when thermmal storage at qualitative difference, have impact on
The serviceability of SBS modified pitch.In order to obtain the modification that hot storage stability is good, can meet road traffic serviceability needs
Colophonium, it is necessary to add modified pitch compatibility stabilizer.
The modified asphalt stabilizer of reported in literature mainly has mediation type and the big class of chemical reaction type two at present.Mediation type stabilizer is usual
The polarity difference between SBS and matrix pitch and relative density difference can only be changed, and obtain the storage stability of short-term, be in harmonious proportion in a large number
The membership that adds of agent affects the original serviceability of modified pitch.Chemical reaction type stabilizer is to send out between matrix pitch and modifying agent
Biochemical reaction, makes matrix pitch and modifying agent organically combine, and then obtains permanent hot storage stability.Chemistry is anti-
The type stabilizer of answering can be divided into again sulphur-containing stabilizer and without sulfur stabilizer, and what current reported in literature was more is sulphur-containing stabilizer.Sulfur-bearing is steady
The host determining agent is Cosan, by the crosslinking between sulfur and rubber, it is achieved the network interpenetrating between matrix pitch and modifying agent,
And then the hot storage stability of acquisition modified pitch, but sulphur-containing stabilizer is difficult to solve modified pitch usability during thermmal storage
The problem of adhesion difference between loss of energy, and modified pitch and mix.
Summary of the invention
The present invention provides a kind of compound SBS modified pitch steady heat storage agent, uses this stabilizer, can not only prevent SBS from changing
Segregation phenomenon is there is in property Colophonium during thermmal storage, and modified pitch usability loss of energy during thermmal storage can be reduced,
Improve the Adhesion property between SBS modified pitch and mix.
In order to achieve the above object, the present invention by the following technical solutions: a kind of Compositional type SBS modified pitch steady heat storage agent,
Its component and percentage composition thereof are as follows: the polyethylene polyamine salt 50～80 containing a chain alkyl and one or more thiazolinyl and aryl
%, antioxidant 5～20%, accelerator 10～30%.
By such scheme, described chain alkyl is C12～C20Alkyl.
By such scheme, described thiazolinyl is any one in vinyl, acrylic and pi-allyl, described aryl be phenyl,
Any one in benzyl and p-methoxyphenyl.
By such scheme, described polyethylene polyamine salt is ethylenediamine, diethylenetriamine, triethylene tetramine, TEPA
Any one in hydrochlorate, phosphate and sulfate.
By such scheme, described antioxidant is any one in antioxidant 264,1010 and 1076, fineness >=
300 mesh.
By such scheme, described accelerator is any one or the combination of two kinds in sierozem power, montmorillonite powder and flyash.
The concrete preparation method of above-mentioned Compositional type SBS modified pitch steady heat storage agent a: chain alkyl and one or many will be contained
The polyethylene polyamine salt of individual thiazolinyl and aryl is heated to flowable state, then antioxidant and accelerator is added thereto, stirring mixing
Uniformly, pulverize after being cooled to room temperature, i.e. obtain product more than 300 mesh.
Beneficial effects of the present invention is as follows:
1. the present invention employing polyethylene polyamine salt containing a chain alkyl and one or more thiazolinyl and aryl is as host, many
Amido in amine at high temperature reacts with the oxygen-content active point of polar compound in Colophonium, it is achieved stabilizer and the change of matrix pitch
Learning and combine, the carbon-carbon double bond in thiazolinyl crosslinks with the carbon-carbon double bond in SBS, it is achieved the chemistry knot between stabilizer and SBS
Close.Make matrix pitch and SBS organically combine by stabilizer, make modified pitch have lasting hot storage stability.
Chain alkyl and aryl in polyethylene polyamine salt improve the compatibility between matrix pitch and SBS；
2. change length or the content of aryl of polyethylene polyamine salt chain alkyl, make the substrate drip that stabilizer is different to arene content
Green grass or young crops has good adaptability；
3. the addition of accelerator accelerates stabilizer and SBS and the interaction of matrix pitch, beneficially modified asphalt cross-linking structure
Formation；
4. the formation of cross-linked structure and the addition of antioxidant, during significantly reducing preparation and the thermmal storage of modified pitch
Aging and degraded；
5. the formation of cross-linked structure improves the homogeneity of modified pitch, improves the serviceability of modified pitch；
6. between polar group and the metal-oxide of absorption and the mix in amine salt more than, there is good affinity, improve and change
Property Colophonium and mix and stir the Adhesion property between material or between modified pitch and roadbed.
