Preparation method of waterproof crack pouring adhesive

The invention belongs to the technical field of road repair material preparation, and particularly relates to a preparation method of a waterproof crack pouring adhesive. The preparation method comprises the steps that diatomite and basalt are taken as raw materials to obtain inorganic matter powder, then orange peels are taken as a raw material to prepare orange peel essential oil, the inorganicmatter powder and the orange peel essential oil are mixed for heating, modified inorganic matter is obtained, the modified inorganic matter has hydrophobicity and a bacteriostatic effect, and silanolgroups on the surfaces of glass fibers and silanol groups in cement concrete are subjected to dehydration cross-linking, so that the waterproof performance of the crack pouring adhesive is greatly enhanced. The preparation method of the waterproof crack pouring adhesive has the advantages that the addition of siloxane can make the contact angles between water molecules and the crack pouring adhesive increased, so that the
