Abstract

The invention relates to a waterproof hard asphalt material and a preparation method thereof. The waterproof hard asphalt material consists of the following components in parts by weight: 26-33 parts of coal tar asphalt, 22-29 parts of urea resin, 12-17 parts of 1-hexene, 6-9 parts of methyl methanesulfonate, 7-11 parts of dimethyl sulfate, 5-8 parts of allyl isothiocyanate and 6-8 parts of acetone. The preparation method of the waterproof hard asphalt material comprises the steps of heating, dissolving, stirring and reacting. The prepared asphalt material not only has excellent waterproofness but also has good hardness and can be widely applied to a waterproof material as an asphalt material and the like.

Description

technical field [0001] The invention relates to an asphalt material and a preparation method thereof, in particular to a waterproof hard asphalt material and a preparation method thereof. Background technique [0002] Asphalt materials have a relatively broad space for use, such as in-depth applications in ground, houses, and coatings. Asphalt materials are mainly divided into coal tar pitch and petroleum pitch. When the asphalt material is applied, it needs to have relatively good waterproof properties. The waterproof performance is poor, and there will be water seepage after the asphalt material is used for a long time. The performance of the asphalt material will also change after water seepage. Not only that, but in some grounds and areas that may involve pressure, if the hardness of the asphalt material is low, the asphalt material will be easily deformed, which will affect the long-term use of the asphalt material. The invention patent with the publication number of...
