Pavement cooling material

Abstract

The invention discloses a pavement cooling material which is formed by mixing the following raw materials in part by weight: 45-55 parts of film forming matters, 35-45 parts of tourmaline and 4-8 parts of aids. Each film forming matter is prepared by mixing epoxy resin, polyamide curing agent and methanol diluent according to the mass ratio of 1:(0.3-0.5):(0.05-0.2); the tourmaline is tourmaline powder and / or tourmaline negative ion powder; and each aid is prepared by dispersing agent, defoaming agent and flatting agent according to the mass ratio of (0.5-1.5):(0.5-1.5):1. The pavement cooling material has the advantages that the tourmaline is taken as a main raw material, the excellent characteristics of the tourmaline is reasonably utilized, and the material converts heat energy into electric energy and other energies through a energy conversion principle, not only has a remarkable cooling effect, but also is low in cost, simple in process and convenient in construction and has the most prominent advantages of intelligence and environmental friendliness.

Description

technical field [0001] The invention belongs to the technical field of road materials, and in particular relates to a road surface cooling material. Background technique [0002] In recent years, my country's expressway construction has developed rapidly, and more than 90% of high-grade pavements use asphalt pavement. However, after the completion and operation of many expressway asphalt pavements in my country, the early damage phenomenon is relatively serious, mainly manifested as: rutting, cracks, loose , oil flooding, subsidence, etc., the appearance of these early diseases greatly shortened the service life of the road surface, causing many expressways to enter the overhaul or renovation period ahead of time, causing a lot of economic losses. Rutting is an important disease of asphalt pavement. Studies have found that high temperature is the most direct cause of rutting. High temperature causes the rheological properties of asphalt to change from viscoelasticity to plast...

Problems solved by technology

In recent years, some scholars have carried out research on pavement cooling materials. By coating a cooling material on the road surface, the heat absorption of the road surface can be reduced, thereby reducing the temperature of the road surface. However, the development of materials is mainly limited to heat reflective cooling materials or Insulation materials, although these materials can achieve certain effects, there are still many problems, such as: (1) The materials used are often of high cost, which will increase the engineering investment; (2) There are many chemical raw materials in the material formula, and they are relatively Most of them are toxic materials, which are easy to cause pollution to the surrounding environment; (3) The formulation process is complicated, causing inconvenience in construction; (4) The durability is poor, which affects the performance of asphalt pavement and slows down the service life of asphalt pavement; (5) The reuse rate is low, Not recyclable, not recyclable, less sustainable
