Problems solved by technology

After the former is mixed and cured with the curing agent, it has the disadvantages of poor aging resistance, high embrittlement temperature, and brittleness when cold
The latter has the disadvantages of poor compatibility between epoxy resin and asphalt, and the resin is easy to separate from the asphalt. A curing agent is added to the mixture of the two for curing, and the cured product obtained is uneven due to the condensation of the resin.

Abstract

The invention relates to the technical field of using epoxy resin thin layer materials for paving pavements directly, in particular to a pavement abrasion-resistant layer based on the epoxy resin. The pavement abrasion-resistant layer is composed of materials of, by weight, 65 parts to 85 parts of epoxy resin, 10 parts to 27 parts of modified epoxy resin, 4 parts to 12 parts of dioctyl phthalate, 14 parts to 28 parts of amino-terminated polyether (for short, ATPE), 15 parts to 35 parts of alicyclic amine hardeners, 10 parts to 25 parts of modified amine hardeners and 30 parts to 50 parts of curing accelerators. The invention relates to a method for preparing the pavement abrasion-resistant layer based on the epoxy resin simultaneously. The method has the advantages of being high in strength, good in toughness, high in shock-resistant strength, good in chemical corrosion resistant, abrasion-resistant, water-proof and anti-freeze performances, and capable of being widely used in construction industries of bridges, roads, buildings and the like, and having broad development prospect.

Description

technical field [0001] The invention relates to the technical field of directly paving road surfaces with epoxy resin thin-layer materials, and more specifically relates to an epoxy resin-based pavement wear-resistant layer and a preparation method thereof. Background technique [0002] In foreign countries, epoxy resin (EP) pavement materials are mature products, and epoxy resin pavement materials have long been used in high-grade highways, airstrips and other places. Compared with traditional materials, roads built with epoxy resin pavement materials have the advantages of high strength, durability, and convenient construction and maintenance. In the last two years, epoxy resin has developed vigorously in my country. According to data reports, most of the epoxy resin and tar mixtures, or epoxy resin and asphalt mixtures are used at present. After the former is mixed and cured with a curing agent, it has the disadvantages of poor aging resistance, high embrittlement temper...
