Description
[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of waterproof coatings, and particularly relates to a non-cured rubber asphalt waterproof coating and a preparation method thereof.
[ background of the invention ]
The non-cured rubber asphalt waterproof coating (hereinafter referred to as non-cured coating) is a novel waterproof material which takes rubber powder, asphalt and special additives as main raw materials and keeps viscous paste for a long time in an application state and has creep property. 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.
However, the disadvantages and performance inherent in the non-curing rubberized asphalt waterproofing coatings currently used require necessary improvements. 1. High-temperature melting is needed before construction, and in the high-temperature melting process, the non-cured rubber asphalt waterproof coating can release a large amount of asphalt smoke along with the rise of temperature. The smoke contains a large amount of substances harmful to human bodies, seriously affects the health of the human bodies and also destroys the surrounding environment. 2. Contains a certain amount of liquid components such as mineral oil, and the waterproof material has creep state in a short period, insufficient cohesive strength, and the material loses creep property and greatly reduces elongation rate with the time. 3. The material cannot be applied in wet ground conditions.
In order to solve the problems, the Chinese patent with the publication number of CN104789127A discloses an environment-friendly smoke-suppressing non-cured rubber asphalt waterproof coating and a preparation method thereof. The invention inhibits the generation of smoke by adding a physical smoke inhibitor and a polymer smoke inhibitor, which can only reduce the generation to a certain extent, and the added smoke inhibitor has negative effect on the viscosity of the waterproof material. The invention discloses a single-component aqueous non-cured rubber asphalt waterproof coating and a preparation method thereof, wherein the single-component aqueous non-cured rubber asphalt waterproof coating greatly improves the initial viscosity, the lasting viscosity, the permeability, the creep property and the aging resistance of the coating by acrylate emulsion with a glass transition temperature and matching with modified liquid tackifying resin and rubber emulsion, but the invention does not solve the problem of smoke generation, and in addition, the solid content of the coating is only 66-69 percent and does not meet JC/T2428-2017, namely 'non-cured rubber asphalt waterproof coating', which is not the non-cured rubber asphalt waterproof coating in the true sense.
Therefore, the existing non-cured rubber asphalt waterproof coating needs to be studied more deeply to solve the problems of smoke pollution, poor creep property, incapability of being constructed on a wet foundation surface and the like.

Samples 1 to 6 are prepared by the methods of examples 1 to 6 of the invention, samples 7 to 12 are prepared by the methods of comparative examples 1 to 5, and performance tests are respectively carried out on 12 samples, wherein the samples 1 to 6 completely meet the requirements of JC/T2428-2017 'non-cured rubber asphalt waterproof coating', partial performance indexes of the samples 7 to 12 are not met, and the table 1 is the main index condition of the tests.
TABLE 1 Main Performance indices of samples 1-12
As can be seen from the results in Table 1, the samples prepared in examples 1 to 6 of the present invention have excellent properties, high solid content, almost no volatile matter, and long-lasting viscous paste, and satisfy the requirements of normal temperature painting construction, and have stronger viscosity and good water resistance.
