Problems solved by technology

The construction methods are mostly hot-melt construction or oily ointment, oily base oil, and polymer glue bonding, which has high energy consumption, danger, large environmental pollution, and wet base surface construction is not firm; use polyvinyl alcohol latex cement Adhesives and other polymer latex cement adhesives bond waterproof membranes, which have a series of problems such as not being resistant to hydrolysis, not being resistant to aging, and being delaminated with the old base surface.
[0003] Chinese patent ZL 01109850.3 discloses a cold adhesive made of 30-40 parts by weight of asphalt, 2-5 parts by weight of ethylene-propylene copolymer, 20-56 parts by weight of 90# gasoline or 120# solvent oil, which contains a large amount of solvent , can only be used for the construction bonding of modified asphalt waterproofing membrane, and the wet base surface and uneven base surface cannot be constructed
The coiled material disclosed in US Patent SU 383724 is made by mixing melted ethylene propylene rubber particles with asphalt that has been preheated to 160-180°C and added with shale tar. High energy consumption, cumbersome operation and unsafe

Abstract

The present invention discloses one kind of adhesive for composite waterproof rolled sheet product and its production process. The adhesive consists of water-thinned latex or water soluble glue powder, water reducing agent, cellulose and additive. It has high adhesion effect, wide use range, high strength, waterproof function, and may be used in the construction of modified waterproof asphalt rolled sheet and polymer sheet with fabric on the surface of new and old concrete and in the repair and waterproof sealing of concrete.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to an adhesive glue used in the construction of a modified asphalt waterproof coiled material or a polymer sheet product with a fabric layer and a production method thereof. technical background [0002] At present, asphalt waterproof membrane or polymer sheet with fabric layer can be produced in a factory and is easy to use, so it is used more and more in construction, especially in roof construction. The modified asphalt membrane with adhesive One side of the adhesive is directly pasted to the concrete surface to achieve the purpose of waterproofing. However, it is not easy to achieve the effects of good waterproof performance, high bonding strength, aging resistance and motion deformation resistance of the adhesive. The waterproof membranes currently seen are mainly modified asphalt waterproof membranes and polymer sheets. The construction methods are mostly hot-melt constructi...
