Adhesive for road antiskid layer and preparation method of adhesive

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.
