Problems solved by technology

However, the biggest disadvantage of asphalt hot mix is: the whole construction process is carried out at high temperature, ready to use after mixing, the hot mix can not be reused after cooling, poor production arrangement plan may cause great waste and equipment usage Low rate and other issues
Although this normal temperature cold mixing process has been greatly improved compared with the hot mixing process, the graded aggregate is composed of many different stones and mineral powders. The performance of the product has a great influence, and special equipment is required for mixing. Moreover, the product starts to react immediately after the A / B components are mixed, so the mixing of the product still needs to be mixed according to the construction dosage plan, and the excess mixing The material cannot be stored, which causes waste and increases the cost, and also limits the scope of use of the cold-mix process. This is an aspect that needs to be improved in cold-mix epoxy asphalt, so that this environmentally friendly construction method can be better promoted and used

Abstract

The invention discloses epoxy asphalt mortar and application. Resin mortar is composed of resin, adsorptive powder and filler and comprises, by weight percentage, 10-40% of resin, 5-50% of adsorptive powder and 0-85% of filler, and the sum of the resin, the adsorptive powder and the filler is 100%. The epoxy asphalt mortar is composed of epoxy asphalt resin, adsorptive powder and filler and comprises, by weight percentage, 10-40% of resin, 5-50% of adsorptive powder and 0-85% of filler, and the sum of the resin, the adsorptive powder and the filler is 100%. Application of the epoxy asphalt mortar in preparing a cold mixng type epoxy asphalt concrete mixture is provided. Application of the epoxy asphalt mortar serving as a coating, a waterproof material or a binding material is provided. The resin mortar product or the epoxy asphalt mortar product is stable in property, is in a loose solid state, does not need to be barreled or sealed, and is low in transportation cost, convenient to use and good in performance.

Description

technical field [0001] The invention relates to an epoxy asphalt cement and its application. Background technique [0002] Resin mastic in the prior art usually refers to a paste or viscous liquid mastic, which is a mixture of resins such as epoxy resin and fillers or other additives. It has a wide range of uses and is used as a coating or adhesive Anticorrosion coatings for steel structure workshops, parts, steel pipes (petroleum oil pipelines), etc., anticorrosion and waterproof coatings for buildings; however, the products in the prior art are usually products with high viscosity and thixotropic liquids, which must be Sealed in barrels, the transportation cost is high, and it is inconvenient to use. The present invention changes the form of the cement by adopting a high specific surface adsorption material, so that most of the liquid components in the product composition are adsorbed and stored in the adsorption material to form loose particles, thereby greatly reducing ...
