Abstract

The invention discloses a two-component interfacial agent and a preparation method thereof. The two-component interfacial agent comprises a component A and a component B; the component A comprises n-butyl acrylate, methyl methacrylate, styrene, tertiary vinyl carbonate, epoxy acrylate monomer, acrylic acid and / or methacrylic acid, initiator, composite emulsifier, water, basic pH regulator and bactericide; the composite emulsifier is a mixture of a reactive emulsifier and sodium dodecyl sulfate; the component B comprises silane coupling agent, ethanol, water, acid pH regulator and bactericide.The interfacial agent of the invention can penetrate and bind in two directions, has high softness and toughness, good air permeability, freeze-thaw resistance, water resistance and aging resistance;is non-toxic, tasteless, pollution-free, free of aldehydes, green and environmental protection. The interfacial agent has excellent acidity and alkalinity resistance and weatherability, and good wallaffinity.

Description

technical field [0001] The invention belongs to the field of building waterproofing, and more specifically relates to a two-component interface agent and a preparation method thereof. Background technique [0002] Emulsion-type wall interface agent is an adhesive made of vinyl acetate-ethylene emulsion (VAE emulsion), vinegar-acrylic emulsion, white latex, polyvinyl acetal modified product, etc., supplemented by other fillers and additives . It is mainly used to treat the surface of concrete, aerated concrete, lime-sand bricks and fly ash bricks, etc., to solve the problems such as hollowing, cracking, peeling and shelling of the plastering layer caused by strong water absorption or smooth surface, which causes the interface to be difficult to bond. It is used for the connection of new and old concrete such as reinforcement of construction joints, beams and columns, reconstruction of old foundations, etc., to enhance the bonding force between old and new concrete and betwee...
