Description
Technical Field
The invention relates to a roof repairing agent and a preparation method thereof, in particular to a fiber-reinforced modified asphalt roof repairing agent and a preparation method thereof.
Background
The water-proof of the building is related to the safety of the building, the energy conservation of the building and the people's livelihood, and the quality of the water-proof engineering directly influences the service life of the building and the peaceful and happy industry of people and influences the normal operation of production. However, the leakage problem of the building engineering, especially the leakage problem of the roof, is high for a long time, and causes great loss and unnecessary trouble to the national property and the life of people. According to the survey of the national institute of building waterproof industry, 65% of new houses in China can leak in different degrees within one to two years, and 65% of building waterproof projects need to be renovated after 6-8 years. Building leakage has become the second major building problem outside of the structure, and has long plagued the broad masses of developers and people.
At present, the leakage treatment of roof engineering mainly comprises two schemes, including integral renovation and local treatment. For the overall renovation, similar to the newly repaired roof, various waterproof coiled materials and waterproof coatings can be selected, the cost is generally higher, the period is longer, and the method is difficult to be applied under many conditions. Therefore, local treatment is carried out on the roof leakage, the method becomes a preferred scheme for solving the problem of building leakage, and the waterproof material is generally selected according to the specific selection of the roof leakage range, the leakage degree, the leakage reason, the environmental characteristics and the like. However, no waterproof material specially used for roof repair exists in the market, various waterproof coatings, sealing materials or grouting materials are used for replacing the waterproof materials, and hot melt asphalt is even directly used as a repair material for some waterproof materials, so that the waterproof materials cannot meet the requirements of a roof repair agent in the aspects of construction performance, application performance and aging resistance. Therefore, aiming at the leakage problem of the building roof, the development of a fiber reinforced modified asphalt roof repairing agent which has strong permeability, good bonding property to a base layer, good construction performance and good adaptability to the base layer, can be applied to most base layers (cement, concrete, high polymers, metal and the like), can also be constructed on a damp base layer and has good aging resistance is urgently needed.
Disclosure of Invention
The invention aims to solve the technical problem of providing a single-component viscous daub-shaped roof repairing agent which has outstanding adhesion, wide temperature application range, good thixotropy, good aging resistance and wide base layer adaptability.

Further, the asphalt is 90# petroleum asphalt.
Further, the tackifying resin is one or a mixture of more than two of coumarone resin, terpene resin, rosin resin, petroleum resin, phenolic resin, epoxy resin and xylene formaldehyde resin.
Further, the polymer modifier is one or a mixture of more than two of nitrile rubber, styrene-butadiene rubber, natural rubber, butadiene rubber, chloroprene rubber, styrene-butadiene-styrene copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), styrene-ethylene-butylene-styrene block copolymer (SEBS) and styrene-ethylene-propylene-styrene type block copolymer (SEPS).
Further, the solubilizer is trilinear oil and/or aromatic oil.
Further, the inorganic reinforcing filler is heavy calcium carbonate and/or talcum powder.
Further, the reinforcing fiber is one or a mixture of more than two of cellulose fiber, polyester fiber, polypropylene fiber and lignin fiber.
Further, the rheological additive is one or a mixture of more than two of organic bentonite, polyamide, fumed silica and castor oil.
Further, the organic solvent is one or a mixture of more than two of gasoline, 120# solvent oil, 140# solvent oil, dimethylbenzene, trimethylbenzene and Stoddard solvent.
The invention further solves the technical problem by adopting the technical scheme that the preparation method of the fiber reinforced modified asphalt roof repairing agent comprises the steps of shearing asphalt, tackifying resin, polymer modifier and solubilizer at a high speed of 160-190 ℃ to prepare modified asphalt, then cooling to 100-120 ℃, adding an organic solvent, continuously cooling to room temperature, adding inorganic reinforced filler, reinforced fiber, rheological aid and antioxidant, and stirring in a high-speed stirrer to obtain the fiber reinforced modified asphalt roof repairing agent.
Compared with various waterproof coatings and sealing materials used for repairing the existing roof, the invention has the following advantages:
(1) wide base layer adaptability: the adhesive has good adhesion to various materials such as cement concrete, cement fiber boards, high polymer materials, asphalt materials and the like, and can be constructed not only on a dry base surface but also on a wet base layer.
