Description
Technical Field
The invention relates to the technical field of non-cured waterproof coatings, in particular to a preparation method of a high-viscosity non-cured waterproof coating.
Background
Waterproof coatings are common building materials in the construction field. Commonly used waterproof coatings are polyurethane waterproof coatings and non-curing rubber asphalt waterproof coatings. The polyurethane waterproof coating is a curing type coating, and polyurethane molecules can be cured into a film through moisture in the air or other components after being coated to play a waterproof role; the non-cured rubber asphalt waterproof coating can not be cured into a film after being coated, and can permanently keep self characteristics such as pressure sensitivity, self-healing property, caking property and the like.
The polyurethane waterproof coating is simple, convenient, quick, flexible and convenient to construct. Non-curing rubber asphalt waterproofing paint is generally used in large and large-area places, and the details of melting paint, brushing and the like are involved in the use, so that the operation is relatively difficult. In addition, the non-cured rubber asphalt waterproof coating contains more asphalt, so that the environment pollution is serious in the preparation process.
The non-solidified rubber asphalt waterproof paint (hereinafter referred to as non-solidified paint) is a waterproof paint which is prepared by using rubber, asphalt and softening oil as main components and adding a temperature control agent and a filler to mix and keep a viscous paste body within the service life. The coating can seal base cracks and capillary holes and can adapt to complex construction operation surfaces; the self-healing adhesive does not solidify for a long time after contacting with air, always keeps the characteristics of sticky colloid, has strong self-healing capability, is sticky when being touched and difficult to peel, and still has good adhesive property at the temperature of minus 20 ℃. The waterproof layer can solve the problems of fracture, flexural fatigue or advanced aging in a high stress state and the like of the waterproof layer caused by the fact that the cracking stress of the base layer is transmitted to the waterproof layer; meanwhile, due to the viscosity of the creep material, the capillary holes and cracks of the base layer can be well sealed, the problem of water channeling of the waterproof layer is solved, and the waterproof reliability is greatly improved; can also solve the problem of compatibility when the existing waterproof coiled material and waterproof paint are used in a compounding way.
The non-cured waterproof coating of the rubberized asphalt is a creep deformation type waterproof coating which does not need film forming, can be independently used as a waterproof coating, and can also be used as an adhesive of a waterproof coiled material to form a composite waterproof layer; the rubber asphalt non-curing waterproof coating is widely applied due to the characteristics of durability, corrosion resistance, high and low temperature resistance, strong caking property, good flexibility, strong self-healing property, simple construction and the like, and the existing rubber asphalt waterproof coating has low viscosity, so that the anti-aging and service life of the existing rubber asphalt waterproof coating are low, and needs to be improved.
Therefore, the invention of the high-viscosity non-cured waterproof coating has positive significance in the technical field of preparation of the non-cured waterproof coating.
