COMPOSITION OF WATER PROOFING MATERIAL FOR REACTION CURING WATERBORNE RUBBER ASPHALT

摘要

The present invention relates to the invention of the method for manufacturing the film having the waterproof agent while having the properties of the water-soluble AR shortening the drying time and the workability of the high efficiency that can substantially increase the thickness of the coating when the coating film once.; The invention is characterized by an implementation of a reduction in air speed and innovative construction to address the fact that the existing water-soluble AR is required much time to dry after coating can not increase thickening of the coating along a long overcoating interval thereto.; Thus the invention flooring crosslinked styrene butadiene copolymer emulsion in the rubberized asphalt per second around the water-soluble and blend the curing agent isocyanate special handling to speed up the drying rate of the coating film was therefore possible that the coating film is applied after as well as the bottom wall in the form of pidomul in courtship it can be used without feedback.; The water resistant agent known in the art is a polyurethane polymer containing isocyanate in Japanese Laid-Open Patent Publication Hei-anion rubberized asphalt emulsion a mixture of SBR latex to St. emulsifier prepared using potassium fatty acid in the oil as asphalt emulsions in No. 4-323215 While this was stirred to curable compositions used as a waterproofing agent known; This product is an existing waterproofing sheets in combination with the case of using the present invention for when laid in a predetermined thickness before the cover sheet not only do not have a separate process to the joint portion of the sheet damp floor, especially in the interior basement waterproofing in an enclosed space We can look forward to excellent effect.; Production method of the water-soluble reaction-curable AR coating film waterproofing agent according to the present invention the composition is mixed with high speed stirring using a special stirrer by introducing parts of the asphalt stock solution maintained at a constant temperature of 40 to 60 parts integer 3-10, 0.1-1.0 parts of an emulsifier the input and keeping the temperature below the specified temperature of styrene butadiene copolymer resin emulsion, and 20 to 40 parts in a test, such as PH, viscosity. While stirring at a low speed defoamer 0.5-2.0 parts of isocyanate stabilizer 2-8 parts of asphalt emulsion stabilizer 2-8 parts flow agent 1-5 In part in sequence and such that complete mixing.; In the case of the cited Japanese Unexamined Patent Publication repellant SBR latex is not a free hydroxyl group reaction with the diisocyanate is to be cured by using an isocyanate mixture was diluted in a part of the solvent and glass some hydroxyl groups in the subject reacted again with an isocyanate It is determined by the structure of.; Solids in the product to reach a given viscosity of 50 to 80 percent weight, the viscosity is adjusted to less than 2500cps, filtered and packaged. Isocyanate is the reaction of the invention, the curable aqueous composition to AR coat Repellent separately packed by 100g-300g a separate vessel by mixing using a stirrer during construction.
