Abstract

The invention discloses an adhesive for a road antiskid layer. The adhesive is formed by mixing 7-10 parts of modified epoxy resin, 3-5 parts of a modified epoxy curing agent and 10-14 parts of talcum powder in parts by weight, wherein the modified epoxy resin is prepared by dissolving a toughening agent, a coupling agent and an anti-aging agent into 80-120 parts of Bisphenol-A epoxy resin and 40-100 parts of soft epoxy resin; the modified epoxy curing agent is prepared by adding a dispersing agent and a defoaming agent into an epoxy curing agent which is 4-8% of the total volume of the Bisphenol-A epoxy resin and the parts of soft epoxy resin. In the prepared method disclosed by the invention, the preparation technology and operation are very simple and convenient and each step is finished at normal temperatures and pressures, so as to bring convenience to industrial production; the prepared adhesive has excellent mechanical property, deformation property, durability and anti-pollution property and can be well bonded with the original road; the adhesive can be well bonded with stones so that the stones are not easy to come off; and the adhesive has low temperature flexibility and does not crack after extrusion.

Description

technical field [0001] The invention relates to a bonding material for an anti-skid layer for road surfaces and a preparation method thereof, in particular to a bonding material for a colored anti-skid layer for road surface engineering and traffic safety and a preparation method thereof. Background technique [0002] In recent years, my country's road construction, especially expressways, has developed rapidly. The improvement of road grade, the increase of traffic volume and the acceleration of vehicle speed put forward higher requirements for the anti-skid performance of highway pavement. The "Technical Standards for Highway Engineering" (JTJ01-88) promulgated and implemented by the Ministry of Communications stipulates that the road surface should have good stability and sufficient strength, and its surface should meet the requirements of smoothness, compactness and anti-skid. There is a certain gap in the skid resistance index of existing highways, especially highway p...
