Description
Technical field
The invention belongs to paint field, and in particular to a kind of sprayable uncured rubber-asphalt waterproof of high temperature resistant resist sagging is applied
Material and preparation method thereof.
Background technology
Uncured rubber asphalt waterproof coating is that a kind of heat molten type polymer rubber modified asphalt waterproof of high solids content is applied
Material.With not solidifying for a long time, there is vis medicatrix naturae, touch and glue, it is difficult to peel off, the features such as low temperature bonding performance is good.Tradition can be solved
It is coating material solidified cann't be solved because basic unit's STRESS VARIATION passes to waterproof layer and caused by waterproof layer cracking, fatigue rupture or place
The problems such as premature aging under high-stress state.Meanwhile, can be multiple with the use of constituting with waterproof roll as bottom attachment coating
Waterproof layer is closed, this waterproof layer can solve that the insoluble string water problems of waterproof roll institute is used alone.
The main component of traditional uncured rubber asphalt waterproof coating is by pitch, regnerated rubber powder, plasticizer, rubber
Oil, modified rubber, tackifying resin etc. are made.For the ease of construction, traditional uncured rubber asphalt waterproof coating can typically set
Counting under high temperature has larger trickling property, and this is easy for causing product heat resistance poor, and high temperature easily slides, trickles, construction at high temperature
The problems such as easy sagging.Particularly this phenomenon of spary coating type product is more obvious, because spraying application requirement product has than relatively low
Viscosity, so being easily caused elevation construction sagging phenomenon occurs, influences product using effect.In order to solve these problems, tradition
Method be to add fire resistant resin or filler inside product to improve the resistance to elevated temperatures of product, but this method is often
Cause following two problems：1st, product viscosity increase, knife-coat application resistance is big, and spraying application temperature drift easily produces danger,
Rifle is easily filled in spraying；2nd, product cohesive force is big, low temperature flexibility is poor, and base material bad adhesion, wriggling is poor.
The content of the invention
To overcome the deficiencies in the prior art, the present invention to provide a kind of sprayable uncured rubber asphalt of high temperature resistant resist sagging and prevent
Water paint and preparation method thereof, using following technical scheme.
A kind of sprayable uncured rubber asphalt waterproof coating of high temperature resistant resist sagging, is calculated by total mass fraction 100%, by
Following material composition：Pitch 15~35%, rubber oil 10~30%, butadiene-styrene rubber 5~10%, random polypropylene 3~10%, increasing
Viscosity resin 5~15%, flyash 15~35% and auxiliary rheological agents 2~11%.
At least one in preferably No. 90 asphalt of above-mentioned pitch or No. 110 asphalt.
At least one in the above-mentioned preferred cycloalkanes rubber oil of rubber oil or aromatic rubber oil, its Main Function is to reduce product
Viscosity, it is easy to production and construction, it helps improve product wriggling and self-healing property.
The styrene-butadiene-styrene (SBS) or random benzene of the above-mentioned preferred linear structure of butadiene-styrene rubber
At least one in ethylene-butadiene copolymer (SBR), its effect is to improve the self-healing property of product, heat resistance, extensibility and low
Temperature flexibility.SBS can select the SBS411 of the LG Corp of South Korea or YH-1401 of Yueyang petrochemical industry；The molecular weight of SBR preferably 20~
300000, combinated styrene content content is preferably 21.5~35, and crude rubber Mooney viscosity is preferably 48~86.
Random polypropylene of the above-mentioned preferred softening point of random polypropylene at 130 DEG C~150 DEG C, its effect is to reduce product life
Viscosity when producing and construct, makes product be readily produced and construct, the interim rigidity that can make the fast quick-recovery of product certain after construction
And be difficult to slide.
Above-mentioned tackifying resin preferably is selected from least one in C 5 petroleum resin or C 9 petroleum resin, by this area public affairs
The material known, its Main Function is the moment caking property and constant adhesion for improving product to base material, and is reduced under the condition of high temperature
The effect of product viscosity.
Above-mentioned flyash material well known in the art, it is cellular structure, and effect is to improve heat resistance.
The above-mentioned preferred organo montmorillonite of auxiliary rheological agents, aerosil, polyamide wax or polyamide modified polyacrylic acid
At least one in ester.Its effect is the shear thixotropy energy for improving product, i.e., be difficult when placing motionless under the condition of high temperature
Trickling, and apply to become prone to the characteristic of trickling after shearing force, product is easy to construction (applying shearing force process), after construction
It is difficult sagging or slides (static process).
The present invention also provides one kind side of preparation of the sprayable uncured rubber asphalt waterproof coating of above-mentioned high temperature resistant resist sagging
Method, is that three-stage feeds intake, and is comprised the following steps：
Pitch under molten condition, rubber oil are pumped into reactor by utilidor, stirring to temperature of charge reaches
After 120 DEG C, stir 10 minutes, put into load weighted butadiene-styrene rubber, random polypropylene and tackifying resin, stirring is warming up to 180 DEG C
Constant temperature is stirred 2 hours afterwards, input load weighted flyash and auxiliary rheological agents, 180 DEG C of constant temperature stir 1 hour after into uniform liquid
Shape, circulating water is cooled to 150 DEG C of filtering and dischargings and gets product.
The present invention has advantages below：
(1) the moment caking property and constant adhesion to various basal planes and coiled material are good, it is possible to achieve repeatedly bond without losing
Effect.
(2) sprayable, knife-coat application, elevation construction is difficult sagging, simple and quick construction.
(3) facade is resistant to 90 DEG C of high temperature without sliding (2mm paste paint film).
(4) low temperature flexibility is good, -35 DEG C of not embrittlements.
(5) without organic solvent, nontoxic pollution-free.
(6) resistance to ag(e)ing is excellent, and 70 DEG C of hot air agings, 168 hours performances are always consistent.
(7) because not using rubber powder in formula, without crossing colloid mill, the energy and thing are saved compared with prior art
Material loss.
(8) three-stage feeding method, production process is simple and easy to control, and the production time is short, can complete within about 5.5 hours in theory
Batch is produced.
Existing product, is generally focused on single or certain several performance indications, and range of application is more single.With existing skill
Art is compared, the best advantage is that, above-mentioned advantage can be simultaneously reached, with good combination property, greatly expand
The scope of application of product.
