Abstract
The invention discloses a modifier of pitch for road and water-proofing material, which comprises the following steps: allocating with mass percent as 20-30% polypropylene, 3-10% epoxide resin, 8-10% polyethylene, 8-10% geoceric acid and 40-60% ethylene distearamide; mixing; stirring for 10-15 min; getting the product. This product possesses good stability and predominant water resistance, which can be fit for all of asphalt.
Description
Technical field
The present invention relates to a kind of asphalt modifier, specifically be used for road and water-proof material.
Background technology
At present, bituminous pavement mainly exists softening, the bellding in road surface in summer, and rut is serious and wave is arranged, gather around bag, winter problem such as cold cracking.In order to improve the quality of bituminous pavement, along with the development of highway communication cause, the notion of asphalt modifier is accepted by people, and modifying asphalt obtains application more and more widely.In prior art, the maximum asphalt modifier of domestic employing is SBS and PE, it is compatible with pitch that but the two all is difficult in use, need special shearing device and higher energy consumption, and construction workability is poor, produce a lot of useless cigarettes, waste gas during construction, cause environmental pollution, the harm operator is healthy, and speed of cooling is slow simultaneously, prolonged the time that is open to traffic, totally unfavorable to transport development.
Consider certain modified effect that Trinidad lake pitch (TLA) has as properties-correcting agent from modification ability aspect.But lake pitch (TLA) flavor is smelly, influences environmental protection, and is subjected to the restriction of resource, and price is higher, and use range is restricted.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of asphalt modifier is provided, can significantly improve asphalt performance, have good stability, softening temperature height, penetration degree are low; Easily mix and stir, do not emanate, dispersing property is good, and is acidproof, alkaline-resisting, water resistance is very superior; Help the recovery and the regeneration of bituminous concrete, be used for simultaneously the road surface safeguard also save time, laborsaving, easily and fast.
Main solution of the present invention is achieved in that
It forms proportioning by weight percentage asphalt modifier of the present invention:
Polypropylene is 20%～30% among the present invention, and Resins, epoxy is 3%～10%, and polyethylene is 8%～10%, and stearic acid is 8%～10%, and ethylene bis stearamide is 40%～60%, and said components is mixed at normal temperatures, stirs to be finished product in 10～15 minutes.
Compared with the prior art the present invention has the following advantages:
1, be applicable to all petroleum pitch, incorporation is low, adds 2%～3% of pitch amount and just can play excellent viscosity reduction modified effect; 2, easily mix and stir, do not emanate, need not specific installation, dispersing property is good, and is acidproof, alkaline-resisting, water resistance is very superior; 3, can obviously improve the bituminous softening temperature, reduce penetration degree, stop wave, gather around the bag phenomenon, can the high temperature resistance rut, can prevent cold cracking again; 4, construction workability is good, can reduce about 30 ℃ of the temperature of paving, and it is very convenient to construct, and can improve sticking power to gathering materials, and reduce and poison soot emissions, environmental, and improve operator's Working environment, and reduce labour intensity, it is healthy to help operator; 5, properties-correcting agent is scattered in the pitch with reticulated structure, so good stability is arranged, can also help the recovery and the regeneration of bituminous concrete, be used for simultaneously the road surface safeguard also save time, laborsaving, easily and fast; 6, obviously reduce energy expenditure, improve work efficiency, significantly improve the bituminous resistance of aging, prolong road work-ing life, reduce compared with similar products and comprehensively make road cost about 30%; 7, because the good flowing properties and the binding property of gathering materials are strong, can obviously improve the compactness of compound, strengthen consolidation effect, reduce voidage, eliminate the potential rut; 8, can significantly improve the viscosity of pitch under 60 ℃, reduce its viscosity under 135 ℃ simultaneously, anti-stick, the agglomeration resistance effect is splendid.
Embodiment
Following the present invention will be further described in conjunction with the embodiments:
Its set of dispense is than (percentage ratio meter by weight) in the embodiment of the invention:
