Abstract

The invention discloses a novel epoxy resin waterproof coating. The waterproof coating comprises a component A and a component B, wherein the component A comprises raw materials in parts by weight as follows: 90-100 parts of epoxy modified polymers, 12-18 parts of a reactive diluent, 3-5 parts of sodium silicate, 1-3 parts of methyl sodium silicate, 2-4 parts of a surfactant, 1-4 parts of a defoaming agent and 300-400 parts of functional filler; the component B comprises raw materials in parts by weight as follows: 22-28 parts of a modified curing agent, 1-4 parts of a cross-linking agent and 2-3 parts of an accelerant. The waterproof coating has a reasonable formula and is simple to construct, high in ageing resistance, good in comprehensive performance, long in service life and capable of being applied to waterproof treatment of roofs, basements, toilets and the like.

Description

technical field [0001] The invention relates to a novel epoxy resin waterproof paint, which belongs to the technical field of concrete building waterproof materials. Background technique [0002] Modern buildings generally use concrete structures when they are constructed. This is because concrete structures have the following advantages: good integrity, and can be poured into a whole; good moldability, and can be poured into various shapes and sizes. Structure; good durability and fire resistance, can resist long-term damage from external factors; low engineering cost and maintenance cost, can reduce building construction costs. Therefore, concrete structures are placed with high hopes, but their own shortcomings are ignored. In fact, concrete is a multiphase composite brittle material. When the tensile stress of concrete is greater than its tensile strength, or the tensile deformation of concrete is greater than its ultimate tensile deformation, cracks will occur in concr...
