Abstract

The invention discloses a hydrophilic epoxy resin binder and a preparation method and an application thereof. The hydrophilic epoxy resin binder consists of the following components according to parts by weight: bisphenol A type epoxy resin, a surface active agent Span, a surface active agent Tween and a catalyst, wherein the catalyst can be tetraethyl ammonium chloride, butyl triphenyl phosphonium bromide, benzyl triethyl ammonium bromide, benzyl triethyl ammonium chloride, 2-methyl imidazole or any combination thereof; the bisphenol A type epoxy resin can be bisphenol A type epoxy resin E-44, E-42, E-35, E-31, E-20, E-14, E-12, E-06, E-03 or any combination thereof; the surface active agent Span can be S-20, S-40, S-60, S-80, S-85 or any combination thereof; and the surface active agent Tween can be T-20, T-40, T-60, T-80, T-85 or any combination thereof. The hydrophilic epoxy resin binder is applied in the preparation process of water permeable pavement materials and high-strength cement products.

Description

technical field [0001] The invention relates to a hydrophilic epoxy resin binder and its preparation method and application. Background technique [0002] At present, due to the needs of the development of the urban ecological environment, the urban ground is gradually covered by impermeable materials such as cement and asphalt to be covered by permeable pavement materials. The traditional method is composed of large particle skeleton and epoxy resin. However, during the use of epoxy resin, due to its lipophilicity and hydrophobicity on the surface, in order to make epoxy resin hydrophilic, it is necessary to try to introduce a hydrophilic molecular segment into its molecular chain or to prepare a complete solution. epoxy resin in water. However, the water-emulsified epoxy resins and hydantoin epoxy resins that are completely soluble in water have the disadvantages of large amount of resin and low wet compressive strength of water-permeable products.
