Embodiment 1

[0023] At room temperature, add 14.4 parts by weight and 5.8 parts by weight of furfural acetone into the reactor, stir continuously at room temperature or 40°C, add 0.08 parts by weight, 40% sodium oxide solution, stir until boiling, and cool for later use. The obtained product is furfurone resin prepolymer solution.

Embodiment 2

[0025] Add 20 parts by weight of bisphenol A epoxy resin into the reaction kettle, heat to 40°C, add 7 parts by weight of furfurone resin prepolymer under constant stirring, and then add 27 parts by weight of Ground calcium carbonate and 40.5 parts by weight of chemically treated SiO 2 , Stir evenly and cool down, then the first component of Zorlipin is obtained.

Embodiment 3

[0027] Add 20 parts by weight of compound amine in the reactor, add 20 parts by weight of heavy calcium carbonate and 47.5 parts by weight of SiO through chemical treatment under stirring 2 , after stirring evenly, the B component of Tsolipin is obtained.

Abstract

A pavement repairing material 'Cuoliping' for the pavement of express way is composed of two components, which are proportionally mixed before them are applied. After it is applied to pavement, it can be solidified within tens min and quickly reach high strength (10-80 MPa).

Description

technical field [0001] The invention belongs to the field of polymer functional materials. It relates to a simple and fast cement concrete repair material-tsolipin, its preparation method and application. Background technique [0002] Concrete pavement staggering on expressways is a very common phenomenon. It makes driving jump, "nods", and causes road surface breakage and sinking, endangering the safety of driving and operation. It is a major problem in expressway maintenance and management. Using quick cement or asphalt concrete or polymer materials (including epoxy resin and polyurethane) is a common method for repairing misalignment. The main problem that above method exists is that 1) construction time is long, and the cohesive force to original pavement concrete is low, can not carry out thin-layer repair on original concrete, needs to knock down original concrete layer, pours leveling staggered platform again. Therefore, at present, for the concrete pavement that ha...
