Abstract
The invention discloses a reactive self-adhesive waterproof roll and a preparation method and application thereof, and relates to the technical field of waterproof rolls. The reactive self-adhesive waterproof coiled material sequentially comprises an upper surface layer, a self-adhesive layer and an anti-sticking layer from top to bottom, wherein the self-adhesive layer comprises the following components in parts by weight: 40-50 parts of asphalt, 7-9 parts of base oil, 3-5 parts of epoxidized SBS, 2-4 parts of styrene butadiene rubber, 7-8 parts of activated rubber powder, 25-30 parts of stone powder and 3-5 parts of coupling agent. The reaction type self-adhesive waterproof roll prepared by the scheme of the invention has good waterproof effect and long service life.
Description
Technical Field
The invention relates to the technical field of waterproof rolls, in particular to a reactive self-adhesive waterproof roll and a preparation method and application thereof.
Background
The self-adhesive waterproof roll has good adhesion and self-healing performance, is widely applied to the waterproofing of roofs of industrial and civil buildings, basements, rooms, municipal works, reservoirs, swimming pools and subway tunnels, and is also suitable for the waterproofing works of roofs of wood structures and metal structures. It is especially suitable for military facilities needing cold construction and re-waterproof engineering of petroleum depot, chemical plant, textile plant, grain depot, etc.
The self-adhesive waterproof coiled material is adhered to the construction surface by the adhesiveness of the self-adhesive layer. The tighter the self-adhesive layer of the self-adhesive waterproof roll is adhered to the construction surface, the better the waterproof effect of the self-adhesive waterproof roll is, and the longer the service life is. Particularly, for some occasions with high water pressure and high waterproof requirements, good bonding is particularly important.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the reaction type self-adhesive waterproof roll as well as the preparation method and the application thereof.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the utility model provides a reaction type self-adhesion waterproofing membrane, reaction type self-adhesion waterproofing membrane is from last to being upper surface layer, self-adhesive layer and antiseized layer down in proper order, the self-adhesive layer contains the composition of following parts by weight: 40-50 parts of asphalt, 7-9 parts of base oil, 3-5 parts of epoxidized SBS, 2-4 parts of styrene butadiene rubber, 7-8 parts of activated rubber powder, 25-30 parts of stone powder and 3-5 parts of coupling agent.
The invention selects the activated rubber powder, enhances the bonding strength of the rubber powder, the asphalt, the epoxidized SBS and the styrene butadiene rubber, and improves the strength and the low-temperature flexibility of the self-adhesive waterproof roll. In addition, the coupling agent is selected to treat the stone powder, an organic layer is formed on the surface of the stone powder, the existence of the organic layer reduces the interface binding force of the stone powder and other components such as asphalt, epoxidized SBS and the like, and the purpose of improving the strength and the thermal stability of the waterproof roll is achieved.
Preferably, the asphalt is 70# asphalt or 90# asphalt; the base oil is at least one of aromatic oil and naphthenic oil; the epoxy value of the epoxidized SBS is 0.15-0.35 mol/100 g; the stone powder comprises at least one of calcium carbonate powder, talcum powder and quartz powder; the coupling agent is an aluminate coupling agent or a titanate coupling agent; the upper surface layer is a PE film or a PET film, and the anti-sticking layer is a silicon-coated isolating film or a composite aluminum film.
The epoxy value of the epoxidized SBS is too low, in the later application process, the number of action points with a construction surface is too small, and the bonding strength of the epoxy SBS and the construction surface is reduced; however, if the epoxy value is too high, the brittleness of the epoxidized SBS is too high, and the bonding strength between the SBS and the construction surface is reduced due to embrittlement of the SBS during use. The inventor proves through experiments that the epoxy value of the epoxidized SBS is 0.15-0.35 mol/100g, the high bonding strength can be ensured, and the service life of the reactive self-adhesive waterproof roll is prolonged.
Preferably, the base oil is a compound of aromatic oil and naphthenic oil, wherein the weight ratio of the aromatic oil to the naphthenic oil is as follows: 1-2: 1.
The aromatic oil is a hydrocarbon compound with an aromatic ring structure in a molecule, wherein the mass percentage of the aromatic hydrocarbon is 70-87%, and the mass percentage of the saturated hydrocarbon is 10-25%; the naphthenic oil is a hydrocarbon with naphthenic hydrocarbon as a main component, wherein the mass percentage of saturated hydrocarbon is 87-93%, and the mass percentage of aromatic hydrocarbon is 5-10%. Aromatic oil and naphthenic oil can be used for improving the processing performance of the self-adhesive waterproof roll, helping the mixing and dispersion of the filler in the asphalt and improving other performances of the self-adhesive waterproof roll, such as low-temperature flexibility and the like. Experiments prove that when the base oil is prepared from aromatic oil and naphthenic oil and compounded according to the proportion, the comprehensive performance of the prepared reactive self-adhesive waterproof coiled material is optimal.
Preferably, the stone powder is calcium carbonate powder, and the calcium carbonate powder can react with an aluminate coupling agent or a titanate coupling agent, so that the dispersion of the stone powder in the asphalt is accelerated, and the strength and the adhesion of the waterproof coiled material are improved.
