Problems solved by technology

[0003] However, the existing epoxy asphalt cement generally uses acid anhydride or organic polybasic acid as the curing agent, so it needs a relatively high temperature to cure. Even if a large amount of accelerator is added, it takes a long time under heating conditions to prepare thermosetting. Epoxy asphalt mastic material

Abstract

The invention relates to room-temperature curing type epoxy asphalt mortar, a preparation method and application thereof, and belongs to the field of green chemical building materials. The room-temperature curing type epoxy asphalt mortar is prepared from a component A, a component B, petroleum asphalt and adsorption powder which are uniformly mixed, wherein the uniformly mixed materials are cured for 7-12 days at the normal temperature of 25-35 DEG C to obtain the room-temperature curing type epoxy asphalt mortar, the component A is composed of the following components in parts by weight: 40-60 parts by mass of bisphenol A epoxy resin, 3-10 parts by mass of dimeric epoxy eleostearate, 4-8 parts by mass of an epoxy diluent and 0-5 parts by mass of a compatilizer, and the component B comprises 28-60 parts by mass of an organic amine curing agent. The prepared epoxy asphalt mortar material capable of being cured at the room temperature has the advantages of being environmentally friendly, safe, wide in application range, capable of saving energy, resistant to deformation, resistant to abrasion, resistant to acid and alkali, waterproof, resistant to corrosion, resistant to deformation and long in service life, can be cured at room temperature to reduce emission of toxic substances and solvent volatilization in asphalt and smoke thereof, and is safe and environment-friendly.

Description

technical field [0001] The invention relates to the field of building materials, in particular to the preparation of room temperature curing epoxy asphalt cement. Background technique [0002] Epoxy asphalt cement is a polymer anti-corrosion and waterproof material. It can be used as a commonly used waterproof and anti-corrosion material for civil building waterproofing, cement-based buildings, foundation pits, foundations, ground, bridge piers, railways, ports, docks, coal mines, oil field drilling and other anti-corrosion and waterproof projects. It has the advantages of wide application range, long service life, weather resistance, deformation resistance, high tensile strength, large elongation, etc., and is convenient for construction. Epoxy asphalt mastic is a finished product, which can be used directly. It can be used at the construction site, and it can be painted and scratched. After curing, it will form a complete layer of rubber-like elastic body, which is a co...
