A kind of creep type epoxy asphalt and preparation method thereof

Abstract

The invention discloses a creep type epoxy asphalt. The epoxy asphalt comprises epoxy asphalt resin, epoxy resin, filler and curing agent. The epoxy asphalt resin comprises asphalt, active agent and epoxy diluent. , this kind can be constructed under normal temperature conditions without high temperature heating, and still has strong creep performance after curing, self-healing, anti-channeling, anti-cracking performance, can repair damaged waterproof layer or fill cracks, To repair concrete cracks, the viscosity of the creeping material enables it to well seal the capillary pores and cracks of the base layer, and solve the problem of water channeling in the waterproof layer; No running water, no dripping, and other physical performance indicators and construction application performance are fully qualified.

Description

technical field [0001] The invention relates to the field of asphalt, in particular to a creep type epoxy asphalt and a preparation method thereof. Background technique [0002] Non-curing rubber asphalt waterproof coating was originally a new type of waterproof material product introduced from abroad at the beginning of this century. It is mainly prepared from raw and auxiliary materials such as rubber powder, asphalt, and additives. There are two main types: one is a product with a high solid content, up to 99%, which is mainly applied by hot-melt spraying; the other is a product containing a high-boiling solvent, with a solid content above 80%, which can be scraped at room temperature. After years of market expansion and application and construction verification, non-curing rubber asphalt waterproof coatings are more and more recognized and relied on by waterproof engineering designers, project construction parties and users due to their unique technical performance and w...

Problems solved by technology

[0003] However, the existing asphalt construction temperature exceeds 150°C, and only the construction method of thermal coating can cause harm and pollution to construction workers and the atmospheric environment.

Moreover, although the non-curing asphalt waterproof coating has certain elongation performance, its elongation performance is limited. Therefore, a creep type that can be applied under normal temperature conditions without high temperature heating, and still has strong creep performance after curing Epoxy asphalt is particularly important
