Description
Technical field
The present invention relates to a kind of asphalt waterproof paint for building and preparation method thereof, belong to chemical technology field.
Background technology
Architectural waterproof material refers to prevent the material of intrusion buildingss such as rainwater, underground water, plumbing, corrosive liquid and airborne moisture, steam.The position that buildings need carry out WATER REPELLENT mainly is roofing, metope, ground and vault, mainly through coating, sprawl, clog, perfusion, technology such as bonding construct.Domestic water-proof material development so far; Basically form that class is more complete, production and the fairly perfect industrial system of utilisation technology, kind comprises five big series products such as modified bituminous pitch coiled material, polymer membranes, waterproof paint, sealing material, patching materials and rigidity water-proofing material.
Pitch is used for waterproof and has very long history, but remains the important materials of buildings waterproof so far, outstanding features such as it has, and low in raw material cost is abundant, easy construction, water-proof function is strong, the waterproof cycle is long.As the principal mode of water-proof material web form and coating form are arranged with pitch.Wherein asphalt felt is to use material the most widely; Product comprises that mainly SBS, APP etc. make material modified polymer modified bituminous waterproof sheet material, and the tire base is main with polyester blank and glass fiber blank, but its use also has restriction; Comparatively suitable as only to large area region, like roof, ground etc.; Can only can not fill up groove, crackle etc. as surface waterproofing; Relatively poor to basic unit's cohesiveness, the whole regional water-proof function of run-down back influence occurs, can not comply with building displacement and distortion etc.The another kind of form of pitch is to use as coating, and main making method is emulsifying water bituminous composition and solvent-borne type bituminous composition.Wherein emulsifying water pitch is made loaded down with trivial detailsly, and disadvantage is owing to be water-based, and its film forming compactness is poor, thereby water-repellancy and stability to aging are all relatively poor; And solvent-borne type is owing to exist a large amount of deleterious organism, can not wait construction indoor.
In view of the shortcoming of two types of materials of above-mentioned pitch, a kind of novel asphalt waterproofing paint is proposed by the people, promptly with a kind of form of sealer pitch is processed water-proof material, generally is called non-curing bituminous composition.Non-curing bituminous composition is in the market mainly processed with modifying asphalt and non-volatile solvent, and it can be used as fills the sealing material, also can big area apply, and be the thickness attitude that can flow at normal temperatures, need not heating and use.It has excellent antiseepage leak resistance, adhesive property, and is easy to use, so very suitable in some occasion.But still there is shortcoming in it: intensity is too low, can trickle, have certain harmful evaporating into when temperature is high grades.Fusing point is than higher, narrow application range.
Summary of the invention
Technical problem to be solved by this invention provides that a kind of formulating of recipe is reasonable, intensity good, can adapt to the asphalt waterproof paint for building of the cryogenic weather condition of high temperature, safety and environmental protection, constant product quality.
Another technical problem to be solved by this invention provides that a kind of technological design is reasonable, production process is simple to operation, the preparation method of the asphalt waterproof paint for building of constant product quality, excellent performance.
It is this asphalt waterproof paint for building that the present invention solves the problems of the technologies described above the technical scheme that is adopted, and its raw material composition is:
Softening agent: 20-25 weight part, properties-correcting agent: 6-8 weight part, pitch: 25-30 weight part, filler: 20-30 weight part, tackifier: 4-6 weight part, crosslinked coupling agent: 0.2-0.3 weight part, dispersion agent: 0.3-0.5 weight part.
As preferably, softening agent of the present invention is third fractional oil and used oil, and the content of third fractional oil is 8%, and the content of used oil is 92%.
As preferably, properties-correcting agent of the present invention is SBS, rubber powder and PP, and the content of SBS is 30%, and the content of rubber powder is 60%, and the content of PP is 10%, and described rubber powder is 80 order tread reclaimed rubber powder.
As preferably, pitch of the present invention is 10# pitch and the 100# pitch mixture according to the 1:4 mixed.
As preferably, filler of the present invention is talcum powder and asbestos wool, and wherein talcous content is 80%, and the content of asbestos wool is 20%.
As preferably, tackifier of the present invention are Gum Rosin and terpine resin, and the content of Gum Rosin is 80%, and the content of terpine resin is 20%.

As preferably, dispersion agent of the present invention is a trisodium phosphate and increase dewaxing, and the content of trisodium phosphate is 33%, and the content that increases dewaxing is 67%.
Pitch uses as water-proof material, and what at first will solve is the drawback that pitch heat is dropped down cold shortness, improves the heat-resisting and cold-resistant ground performance of pitch.The pitch of different labels has certain difference, and 100# and two kinds of pitches of 10# are adopted in this invention, through experiment find both proportionings use to coating heat-resistingly resist cold, performance such as viscosity is favourable, also is beneficial to the allotment of other component.This kind asphalt waterproofing material modification composition mainly is ground rubber and SBS resin; Ground rubber is the rubber grain that is ground into after damaged tire reclaims; Comparatively cheap, pitch heat dropped down cold short to improve effect better, and bituminous aging resistance and physical strength are also had bigger improvement; 5% above SBS makes pitch have island structure, has strengthened the heat-resisting winter hardiness of pitch greatly, and gives pitch excellent intensity; A small amount of PP can increase the thermotolerance of modifying asphalt effectively.Secondly, must be comparatively convenient during bitumen construction.Because the modifying asphalt yield temperature wants more than 180 ℃, the fusion construction is cumbersome, thus with third fractional oil and used oil as softening agent, make it have lower yield temperature, convenient construction; Can make that bituminous composition intensity significantly reduces, not anti-extruding but too much increase third fractional oil, and thermotolerance is reduced.Adding modified rubber is contradiction with adding softening agent heat-resisting and cold-resistant to bituminous, must seek suitable proportioning, and bituminous composition (like 60 ℃ of STs) under weather high temperature is not trickled, and can it melt construction (as being heated to 120 ℃) easily again.Moreover for pitch is bondd with base material better, need to add tackifier, be to add rosin and terpine resin here, owing to both softening temperatures, price, viscosity difference, so need be used, this system can keep viscosity preferably under-10 ℃ of environment.Talcum powder and bitumen compatibility are good, and be beneficial to the pitch thermotolerance; Asbestos wool can strengthen the pitch network structure, increases.Maleic anhydride and aluminic acid ester can make pitch matrix and rubber, mineral filler better combine, thereby increase anti-permeability performance, and strengthen intensity and thermotolerance.The favourable fillers dispersed of trisodium phosphate ability, and wax more is prone to melt after making the asphalt system heating.
This system bituminous composition also has characteristics, and existing bigger intensity has good thixotropic creep effect again.Promptly creep property is preferably arranged, and under less external force effect, can keep intensity preferably again when big (being more than 50% of shearing resistance), do not produce obvious creep stressed.So this coating can well move with building, can discharge internal stress long-term when stressed, it is aging to slow down stress.In addition, this invention coating is stabbed at the figure layer to be split under the situation, can be well self-closing, when temperature is high, can the oneself bond again, and promptly have the ability of self-healing.
The SBS structure is star-like in the above material, the better network structure of favourable formation; Rubber powder is 80 order tread reclaimed rubber powder, in heating easy desulfurization and reacting with pitch during blend; The talcum powder particle diameter is bigger to the oil number influence, and fineness is 100 orders here, and meticulous mistake slightly all is unfavorable for asphalt performance; Asbestos wool length is 2mm, selects easy dispersive kind; The rosin softening temperature is 110 ℃ here, and the terpenes softening temperature is 150 ℃.
The present invention solves the problems of the technologies described above the preparation method of a kind of asphalt waterproof paint for building of technical scheme that is adopted, and its process step is:
A, pour softening agent into reaction kettle heating, and stirring at low speed, stirring velocity is 80 commentaries on classics/min, after 180 ℃, adds properties-correcting agent, increases stirring velocity to 200 commentaries on classics/min simultaneously.Fully stir that 40min is above all to be melted to properties-correcting agent;
