Abstract

The invention discloses a heat-solidity epoxy tar material, preparing method and specific dissolving-reinforcing agent, which comprises the following steps: allocating the raw material with 100% tar, 20-40% epoxy resin, 20-40% hardener and 20-60% heat-solidity epoxy tar; blending evenly; heating to 80-90 deg.c; stirring evenly; solidifying under 100-120 deg.c for 0.5-7h; obtaining the product. The invention provides a specific dissolving-reinforcing agent of heat-solidity epoxy tar material, which contains weak-polarity high-grade fat carbon chain and strong-polarity Mannish alkaline or compound of epoxy resin and polyol.

Description

technical field [0001] The invention relates to an asphalt material, a preparation method and an additive thereof, and is a building material, in particular to a thermosetting epoxy asphalt material, a preparation method and a special compatibilizer thereof. Background technique [0002] Asphalt is a construction material used for paving roads or bridges, waterproofing buildings, and other purposes. Bitumen is a natural thermoplastic and is inexpensive compared to other synthetic thermoplastics. It is precisely because of the thermoplasticity of asphalt that its performance at high and low temperatures is not ideal. Asphalt tends to flow at high temperatures, but is brittle and prone to cracks at low temperatures. For example, in the high temperature season, the asphalt pavement is prone to rutting under heavy load; in the low temperature season, the asphalt pavement is prone to cracks. If cheap asphalt could be transformed into a thermoset material that does not melt or ...
