Description

A kind of fiber reinforcement type modified pitch roofing healant and preparation method thereof
Technical field
A kind of roofing healant of the present invention and preparation method thereof, and in particular to a kind of fiber reinforcement type modified pitch roofing is repaiied Tonic and preparation method thereof.
Background technology
Buildings waterproof concerns building safety, building energy conservation and common people's people's livelihood, and the quality of waterproofing quality is directly influenced The service life of building and living and working in peace and contentment for the people, while influenceing the normal operation of production.However, architectural engineering seepage is asked Topic, especially roof leakaging problem remains high always for a long time, to national wealth and people's lives cause very big loss and Unnecessary worry.Investigated according to building waterproofing industry association of China, the new house one of the current country 65% to occurring in two years Different degrees of seepage, 65% construction waterproofing engineering needs renovation after 6~8 years.Leakage of building has become outside structure Two big building problems, the numerous developers of long-standing problem and the people.
At present, roofworks treating seepage mainly includes two schemes, including overall overhaul is administered with local.For entirety Overhaul, it is similar with new roofing of repairing, various waterproof rolls and water-repellent paint can be selected, is substantially more expensive, the cycle is longer, and It is difficult to be applicable in many cases.Therefore, local improvement is carried out to roof leakage, as the first choice side for solving Leakage Problems in Buildings Case, the selection of its waterproof material typically should specifically be selected according to roof leakage scope, leak magnitude, leakage cause and environmental quality etc. Select.However, so far in the market also not dedicated for roofing repair waterproof material, more with various water-repellent paints, sealing or Grouting material is substituted, and some are even directly with hot-melt asphalt as patching material, and these materials are either in workability, application All it is difficult to the requirement for meeting roofing healant in terms of performance and ageing-resistant performance.Therefore, for the leakage problems of building roof, urgently A permeability to be developed is strong, good to basic unit's caking property, and application property and basic unit adapt to, and both can be applied to most basic units (cement, concrete, macromolecule, metal etc.), can also construct in wet base, and the fiber with good ageing-resistant performance Enhanced modified pitch roofing healant.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of with prominent adhesiveness, broad Acclimation temperature model Enclose, good thixotropy, good ageing-resistant performance and the sticky clay shape roofing repairing of the one-component of extensive basic unit's adaptability Agent.
The technical scheme that the present invention solves the use of its technical problem is that a kind of fiber reinforcement type modified pitch roofing is repaired Agent, is made up of the raw material of following mass fraction, wherein, pitch is 20~50%, and tackifying resin is 5~20%, polymer modification Agent is 0.2~10%, and solubilizer is 0.5~5%, and inorganic reinforcing filler is 20~80%, and auxiliary rheological agents are 0.5~2%, enhancing Fiber is 1~10%, and antioxidant is 0.1~1.0%, and organic solvent is 20~30%, and the quality hundred of all raw material components It is 100% to divide than sum.
Further, the pitch is 90# asphalt.
Further, the tackifying resin be coumarone indene resin, terpene resin, rosin resin, Petropols, phenolic resin, Mixture more than one or both of epoxy resin and xylene formaldehyde resin.
Further, the polymer modifiers is nitrile rubber, butadiene-styrene rubber, natural rubber, butadiene rubber, neoprene rubber Glue, styrene-butadiene-styrene (SBS), SIS (SIS), benzene second Alkene-ethylene-butylene, Styrene block copolymer (SEBS) and styrene ethylene-propylene-styrene type block copolymer One or both of (SEPS) mixture more than.
Further, the solubilizer is to subtract third fractional oil and/or aromatic naphtha.
Further, the inorganic reinforcing filler is powdered whiting and/or talcum powder.
Further, the reinforcing fiber is one in cellulose fibre, polyester fiber, polypropylene fibre and lignin fibre Plant or two or more mixtures.
Further, the auxiliary rheological agents be organobentonite, polyamide, aerosil and castor oil in one kind or Two or more mixtures.
Further, organic solvent is gasoline, 120# solvent naphthas, 140# solvent naphthas, dimethylbenzene, trimethylbenzene and Stoddard Mixture more than one or both of solvent.
The present invention further solve its technical problem use technical scheme be, a kind of fiber reinforcement type modified pitch roofing The preparation method of healant, by pitch, tackifying resin, polymer modifiers, solubilizer, in 160~190 DEG C of high speed shears, system The modified pitch obtained, is then cooled to 100~120 DEG C of addition organic solvents, continues to be cooled to room temperature, adds inorganic enhancing and fills out Material, reinforcing fiber, auxiliary rheological agents, antioxidant, are stirred under high speed agitator,.
Compared with the repairing of existing roofing various water-repellent paints, encapsulant used, the present invention has advantages below:
(1) extensive basic unit adaptability:It is each for cement concrete, cement fibrolite plate, high polymer material, asphalt material etc. Planting material all has good adhesiveness, can not only dry basal plane construction, and can be constructed in wet base.
(2) prominent adhesiveness:Adhesion strength for cement concrete basic unit reaches more than 0.6Mpa.
(3) broad Acclimation temperature scope:Modified pitch roofing healant product heat resistance of the present invention reach 170 DEG C with On, the low temperature flexibility limit is below -15 DEG C, with broad temperature application range.
(4) good workability:Modified pitch roofing healant product of the present invention had both been suitable for plane construction, also was adapted for It is once thick to apply 3mm not saggings in elevation construction, with good thixotropy.
The present invention is applied in crack repairing, joint seals such as roofworks, reservoir dam, drainage pipelines (undrinkable water) Deng.
