Ultra-thin layer repairing agent and construction technology thereof

Abstract

The invention discloses an ultra-thin layer repairing agent, which comprises a polymer modified polymer liquid material and cement powder according to a mass ratio of 1: 4, wherein the polymer modified polymer liquid material comprises the following raw materials in percentage by weight: 40-65% of modified polymer building emulsion, 30-55% of clean water, 1-5% of a film forming additive, 0.1-0.5%of butyl citrate, 0.1-0.5% of a bactericidal preservative, 0.1-1% of a dispersant and 0.2% of a defoaming agent; the cement powder comprises the following raw materials in percentage by weight: 30-50%of ultra-high strength low alkalinity sulphoaluminate cement, 10-30% of ordinary portland cement, 5-20% of heavy calcium, 1-10% of an expansion agent, 20-40% of refined high wear-resistant graded stones, 0.1-1.5% of a high-performance polycarboxylate water reducer, 0.01-0.5% of a high-efficiency setting accelerator/retarding material, 0.1-5% of redispersible latex powder and 0.01-0.07% of a powder defoamer. The ultra-thin layer repairing agent has the advantages of high strength, high adhesion, good wear resistance, noise reduction, low shrinkage rate, no crack, etc.

Description

technical field [0001] The invention relates to an ultra-thin layer repairing agent and its construction technology. Background technique [0002] In the laying of traffic road bridge decks and building construction, including shopping malls, garages, basements, warehouses, etc., concrete is usually used for operations, but the setting time of concrete is slow, the maintenance cost is high, and it is prone to pitting, hollowing, peeling, Hulling, cracks, exposed tendons and other diseases. The existing repairing technology has the following disadvantages: large shrinkage, poor bonding performance, poor construction workability, low wear resistance, poor durability, and low later strength. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultra-thin layer repair agent with high strength, good wear resistance and low drying shrinkage and its construction process. [0004] In order to solve the problems of the te...
