Cementing material for durable colored pavement and preparation method thereof

Abstract

The invention discloses a cementing material for a durable colored pavement and a preparation method thereof. The cementing material consists of a component A, a component B and a filling agent, wherein the component A comprises 72-75 parts of epoxy resin, 18-20 parts of an active diluent, 10-15 parts of a toughening agent, 3 parts of a silane coupling agent, 0.5-0.7 part of an antioxidant and 0.5-1 part of an ultraviolet light absorber; the component B comprises 18-20 parts of a type A curing agent, 23-25 parts of a type B curing agent, 7-10 parts of a tough curing agent, 2-5 parts of an accelerant and 15-30 parts of white carbon black; the filling agent comprises 0.3-0.5 part of aramid fiber and 0.2-3 parts of an inorganic pigment; the parts refer to parts by weight, and the weight ratio of the component A to the component B is 100:50. The cementing material has the advantages of convenience in processing and use, high cementing capability, capability of meeting the requirement of pavement stability, appropriate flexibility, resistance to water damage and fatigue, high weather resistance of color, long service life and stable character.

Description

Technical field [0001] The invention relates to a cementing material for roads, in particular to a cementing material for durable colored pavement. Background technique [0002] Generally, the color of urban roads is relatively single or cement pavement (white) or asphalt pavement (black). The appearance of colored pavement is more and more widely accepted. Today's people prefer a colorful world. What is needed when paving a colored pavement is one A brand-new cementing material. [0003] In recent years, there have been attempts to apply polymer materials to color pavement, but there are always defects of this kind. There are three main types of common defects. One is the problem of adhesion: the main manifestation is that the gravel is often taken away by the wheels, and more What's more, it is peeled off from the original ground, which directly leads to the failure of the colorful pavement. The second is the problem of flexibility: because the cement is too hard, the color pav...

AI Technical Summary

Problems solved by technology

[0003] In recent years, there have been attempts to apply polymer materials to colored pavement pavement, but there are always defects of one kind or another. The common defects mainly fall into three categories. What's more, it is stripped from the original ground, which directly leads to the failure of colored pavement paving

The second is the problem of flexibility: because the cementing material is too hard, the colored pavement will often crack and age prematurely due to insufficient deformation, which will affect the durability of the colored pavement; Water damage and other requirements

The third is the problem of fading: due to the good coloring of organic pigments, there are many users, but the weather resistance is poor, and the problem of fading within a short period of time is inevitable
