Abstract

The invention provides waterproof sealing paste producing chemical crosslinking and physical mortising with cement. The sealing paste is characterized by comprising the following raw materials in parts by weight: 40-60 parts of synthesized rubber latex, 20-30 parts of rubber modified emulsified asphalt, 1-2 parts of a functional additive, 10-30 parts of filler, 0.5-5 parts of plasticizer, 1-3 parts of a thickener and 2-5 parts of water. A principle is that part of molecules in the synthesized rubber and the asphalt are coupled into macromolecules with reactivity under the coupling effect of the functional additive; when the macromolecules are contacted with a basic surface, the non-reactivity molecule sections of the rubber and the asphalt form a physical adsorption effect with the basic surface, and the reactivity molecule sections react with the basic surface to form a chemical bonding effect so as to generate a powerful bonding force; and the bonding effect is difficultly influenced by outside environment factors after the bonding operation is finished. Therefore, the sealing paste is very excellent in waterproof performance.

Description

technical field [0001] The invention relates to a waterproof sealing paste, in particular to a sealing paste capable of chemical adsorption with cement or concrete base surfaces. Background technique [0002] Waterproof sealant is one of the waterproof materials. It is a filling and sealing material for structural joints, construction joints, board joints, door and window joints, and various joints that are intentionally set in design and produced during construction. Waterproof sealant is often used in combination with other waterproof materials such as waterproof membranes and waterproof coatings to achieve excellent waterproof effects for buildings. Waterproof sealants mainly include polyurethane sealant, silicone sealant, polyacrylic resin sealant, polysulfide sealant, synthetic rubber-based sealant, modified asphalt sealant, etc. Polyurethane sealant, silicone sealant and polysulfide sealant have high production costs and are rarely used in large-area projects, and the...
