Problems solved by technology

[0004] The traditional epoxy resin base treatment agent is brittle after film formation, and it is difficult to maintain continuous and effective bonding with the sprayed polyurea waterproof layer. The bonding between polyurea and concrete is attenuated, especially the peeling strength is greatly reduced, which accelerates polyurea waterproofing. overall layer failure

Abstract

The invention provides an epoxy resin base layer treating agent used for spraying polyurea, comprising the following components in parts by weight: 20-65 parts of epoxy resin, 1-20 parts of reactive diluent, 10-50 parts of modified amine curing agent, 2-50 parts of toughening agent (curing agent), 0.5-5 parts of accelerator, 0.05-5 parts of high-performance assistant, 0-80 parts of mixed solvent and 0-80 parts of filler. The invention also provides a preparation method of the epoxy resin base layer treating agent. The polyurea has better strength and toughness after being cured to form a film and has good reinforcing and strengthening actions on concrete base material; capillary porosities and pinholes on the surface of the surface of the concrete base material can be effectively sealed; adhesive force between the concrete base layer and the polyurea is obviously improved; influence and attenuation on the polyurea and the adhesive force by environmental changes can be lowered; and polyurea prevention effect is improved.

Description

Technical field: [0001] The invention relates to a base treatment agent for concrete surface sprayed with polyurea waterproof paint, a two-component or multi-component epoxy resin base seal treatment agent and a preparation method. Background technique: [0002] Spraying polyurea elastomer technology is a new type of solvent-free developed to meet the needs of environmental protection after the low (no) pollution coating technologies such as high solid coatings, water-based coatings, radiation curing coatings, and powder coatings in the past 10 years abroad. , Pollution-free green construction technology is a major progress and the latest development of structural waterproof technology. Polyurea technology organically combines the excellent performance of polyurea with the construction technology of rapid spraying and on-site curing, so that it shows incomparable advantages in engineering applications. The application of polyurea technology in China's Olympic venues, Beijin...
