Description
Technical field：
The invention belongs to asphalt additive production fields, and in particular to a kind of SMC pitches cold-patch agent and preparation method thereof.
Background technology：
SMC pitch cold-patch agent is the methyl styrene based block copolymer to be extracted from waste plastic, rubber etc.
(Styrenic Methyl Copolymers abbreviation SMC) be primary raw material, add certain type and quantity surfactant,
Resin etc., miscible manufactured organic solution, as asphalt cold repairing modifying agent.Asphalt modifier when cold-repairing material production can be regarded
It uses, is suitable for the pit repairing of each standard highway bituminous paving.The pavement performance of SMC cold-repairing materials is suitable with traditional hot-patch material,
The repairing and maintenance on the various road surfaces such as highway, ordinary highway, town road, airport, bridge and tunnel are can be widely used for, it is real
Border service life is durable, can make up the previous undesirable technological deficiency of cold mixing material pavement performance.
About 100 DEG C lower than hot-mix asphalt mixture or so of mixture temperature when cold repairing asphalt mixture produces, not only
Producing cost is low, it is important that reduces the aging of pitch, can extend the service life of cold-repairing material.It is said from work progress, heat drip
Green mixture construction is by temperature limiting, it is desirable that temperature is not less than 5 DEG C, and otherwise asphalt Forming Quality will reduce, and cold
The construction of feed supplement then is not influenced to construct under subzero 15 DEG C of temperature by temperature, and quality can still ensure that cold-repairing material has simultaneously
Standby good water resistance, in rain and snow with can construct under the conditions of the ponding hole punished, when bottom condition is good
Even without spread adhesion coating pitch, thus bring great convenience to the maintenance on road surface, in addition, cold-patch agent be it is a kind of at
Product can be stored, on-demand.There is the cold asphalt mixture for meeting high-quality raw material requirement good adhesion property, material to match
System can be adjusted according to various regions varying environment condition and purposes, be bituminous concrete, coagulating cement for repaired object
Without apparent selectivity when soil, bridge floor material, all kinds of base materials.
When repairing bituminous paving pit-hole using cold asphalt mixture, without large-scale mixture laying and compacting equipment, only rely on small
The simple construction equipment of type, when unconditional even available artificial process pave molding by Construction traffic and road by vehicle
Can complete compacting link, stock with take with, it is not high to working space and personnel requirement, work progress have greatly flexibly
Property.
Invention content：
The present invention provides a kind of SMC pitches cold-patch agent and preparation method thereof, and preparation method is simple, superior performance, bond
Property it is good, intensity is high.
A kind of composition of raw materials of SMC pitches cold-patch agent, including methyl styrene based block copolymer, reinforcing agent, surface work
Property agent and resin, wherein the mass fraction of various raw materials be 75-82 parts of methyl styrene based block copolymer, 2-3 parts of reinforcing agent,
15-20 parts of 1-2 parts of surfactant and resin；Wherein reinforcing agent is lignin, polyester, one kind in polyacrylonitrile three, two
Kind or three kinds of mixture, surfactant are ethylene oxide polymerization surfactant and AB type block macromolecular surface-actives
One or both of both agent mixture, resin are epoxy resin, phenolic resin, one kind in polyamide three, two
Kind or three kinds of mixtures.
Preferably, the mass fraction of various raw materials is methyl styrene class in a kind of composition of raw materials of SMC pitches cold-patch agent
17 parts of 79 parts of block copolymer, 2.5 parts of reinforcing agent, 1.5 parts of surfactant and resin.
A kind of production technology of SMC pitches cold-patch agent, it is characterised in that：
The first step：It weighs, methyl styrene based block copolymer 75-82 is weighed according to the raw material proportioning in claim 1
Part, 2-3 parts of reinforcing agent, 1-2 parts of surfactant and 15-20 parts of resin；
Second step：Stirring, by after above-mentioned weigh methyl styrene based block copolymer, reinforcing agent, surfactant and
Resin pours into same blender, stirs 1-5 minutes at normal temperatures.
Simple production process of the present invention is not necessarily to special process and equipment, can be complete using the original equipment of cold and hot feed supplement
At production, and production process is easy, quick.SMC cold-repairing material storage periods, are long, on-demand, not by weather and hole size
Limitation, surplus material can be continuing in repairing next time, not cause the waste of mixture.SMC cold-repairing material adhesion strengths are strong, with drip
Green concrete, cement concrete, metal, wooden road surface is combined preferable cohesive force, and the hole after repairing is not likely to produce
The bad phenomenons such as fall off, be cracked, and is not required to repeat to repair.SMC cold-repairing materials are improving pavement performance and are making compared with traditional cold-repairing material
With suitable with traditional cold mixing feed supplement price in the case of the service life, compared with traditional hot-patch material and temperature compensation material, the energy of consumption is released
The pernicious gas put is less.
