Description

Cold bonding non-cured modified asphalt waterproof material, preparation method thereof and waterproof roll containing material
Technical Field
The invention belongs to the technical field of building waterproofing, and particularly relates to a cold bonding non-curing modified asphalt waterproof material, a preparation method thereof and a waterproof roll containing the material.
Background
At present, the waterproof field of buildings usually adopts flexible waterproof materials such as waterproof paint, waterproof coiled materials and the like to be used independently or the flexible waterproof materials and the waterproof coiled materials are used in a composite way to achieve the aim of building waterproofing. According to investigations, the waterproof coatings for buildings can be basically classified into a curing type, a solvent type and an emulsion type. The curing type waterproof building coating is characterized in that after a solvent or water volatilizes to generate chemical crosslinking, the coating is cured into a coating film to play a waterproof role; because the waterproof concrete or mortar base surface is complex (dust, unevenness, large water content and the like), the bonding strength and the waterproof performance of the coating and the base layer are influenced; and the tearing resistance of the coating is poor, when the substrate of the coated object has cracks, the coating film is also damaged, or only has slight extension, but does not have the real capability of resisting the substrate cracking. Once the coated substrate is deformed and cracked, the coating film is cracked to lose the waterproof function. The existing domestic modified asphalt waterproof coatings are mainly solvent-based and water-emulsion, and the waterproof coatings are not ideal in the aspects of mechanical property, waterproof property, durability and the like, creep flow often occurs at high temperature, brittle fracture delamination occurs at low temperature, and the waterproof property of a building is seriously influenced. Meanwhile, the coating contains volatile solvent or water, and is particularly used in kitchens, toilets and buildings with poor ventilation in the construction process, so that the period of construction operation is prolonged, and health influence is caused to operating personnel.
The waterproof coiled material is covered on the base layer by hot melting, welding, anchoring or adopting construction methods such as self-adhesive glue and the like to play a waterproof role. The construction of the waterproof coiled material has the advantages that firstly, the environment is poor, the construction quality is affected, secondly, the overlapping seams are more, and water leakage caused by bulging of the overlapping seams is easy to cause; and thirdly, although the waterproof roll has certain extensibility, the constructed base layer has cracks or the building structure is deformed, and the waterproof roll only has slight extension and does not have the capability of resisting the cracking of the base layer, so that the roll cracks and loses the waterproof effect.
In summary, the waterproof material which is the most ideal waterproof material at present has the following characteristics: 1. the adhesive has the adhesive capacity with the complex base surface condition of concrete or mortar at normal temperature or low temperature; the problem of high requirement on the base layer in the coating construction process is solved. 2. Never cured in use engineering, and has good adhesiveness, extensibility, self-healing property and low-temperature flexibility.
At present, the technical problems are also solved by adopting a non-cured rubber asphalt waterproof coating, and the non-cured rubber asphalt waterproof coating (or called creep type rubber modified asphalt waterproof coating) is taken as one of asphalt coatings and is widely accepted by the market due to the characteristics of no flowing at high temperature, no cracking at low temperature, strong weather resistance, acid resistance, strong crack resistance and the like. The waterproof paint can be used as a film waterproof layer independently, and can also be used with polymer (SBS or APP) modified asphalt waterproof coiled materials, polymer waterproof coiled materials and the like in a composite mode to form two waterproof layer protections, namely a film coating layer and a coiled material layer, and meanwhile, the paint layer is also used as an adhesive of the coiled materials. The non-curing rubber asphalt waterproof coating has the following disadvantages in the practical use engineering: 1. the existing rubber modified asphalt has the advantages that in the modification process, the addition of an elastic material can increase the temperature of the ingredients of the product when the elastic material is dissolved, the time for ingredients is prolonged, the risk of polymerization in the modification process is increased, the viscosity of the modified asphalt is increased when the elastic material is dissolved, the preparation process of the waterproof coating needs more component solvents for dilution and dispersion, and the oil leakage phenomenon occurs in the actual use engineering. 2. The expected waterproof effect can be achieved only by construction with a hot melting method, and during construction, non-renewable fuels such as natural gas and methane are required to be combusted and heated or electric power is used for hot melting construction, so that the operation is complex and energy is seriously wasted. However, the non-cured rubber asphalt waterproof coating has the following defects: 1) the construction can be carried out only by heating to 180 ℃, so that energy waste exists, great inconvenience is brought to the construction, and the application range is limited; the energy consumption of heating construction is large; 2) at 180 ℃, the asphalt smoke also causes certain harm to the environment and constructors; 3) the wet interface has poor adhesion effect and cannot be directly adhered and paved.
The double-sided self-adhesive polymer modified asphalt waterproof coiled material has the advantages of good extensibility, strong cohesiveness, wet operation construction and the like. At present, after the conventional waterproof roll is constructed, once the waterproof layer is damaged, water can flow around along the waterproof roll. The double-sided self-adhesive polymer modified asphalt waterproof coiled material utilizes a special self-adhesive binder layer to form super-strong adhesion with polymer cement slurry; the cement mortar and the flexible double-sided self-adhesive waterproof roll material which are fully maintained are combined rigidly and flexibly to form an upper-insurance type waterproof effect, and defects such as shell forming and hollowing are effectively avoided. Therefore, the water channeling phenomenon of the traditional coiled material is fundamentally solved, the construction quality of the waterproof coiled material is greatly improved, and meanwhile, the cheap binder of cement mortar is utilized, so that the economic and practical effects are achieved.
At present, modified Zheqing waterproof coiled materials are widely used in various building waterproof projects, but due to the adoption of a hot melting construction process, the construction has the problems of environmental pollution, energy waste and potential safety hazards on site, the technical characteristics of cold construction of the self-adhesive modified Zheqing waterproof coiled materials are highly recognized, but due to the defects of the materials, the materials are widely popularized and manufactured with resistance in the market, and the specific expression is that firstly, in order to achieve the self-adhesive performance of the materials, certain performance indexes of the materials have to be reduced, such as heat resistance indexes, so that the materials cannot be adopted in certain high-temperature environments, such as exposed roofs and vertical wall waterproof parts in high-temperature areas; secondly, the technical index of the material is single, and the requirement of the construction industry on the multi-azimuth waterproof material cannot be met; thirdly, no matter the Zhe blue waterproof roll material is modified by a hot melting method, or the Zhe blue waterproof roll material is self-adhered by a pre-paving and re-adhering method or a wet paving method, the phenomenon that the waterproof layer is cracked and water leakage occurs due to external stress damage caused by cracking and deformation of the base layer and the like is mostly existed in the use process of the material.
